| 141 | Method and system for raising and castrating cattle | US09392695 | 1999-09-09 | US06270507B1 | 2001-08-07 | Michael P. Callicrate |
| An apparatus and method for use in raising cattle, and in particular bulls, wherein bulls are: (a) fed a particularly nutritious liquid having a distinctive odor prior to weaning; (b) fed a combination of this liquid and conventional feed after weaning in a feedlot; (c) castrated using a ligation tool that provides a ligating tension to endless elastomeric ligation bands wherein the tool indicates the tension applied to such ligation bands; and (d) treated for infection prevention at least around the time of castration. Accordingly, cattle growth is accelerated due to enhanced nutrition, reduction in disease and a reduction in the stress upon the cattle. Furthermore, late castration of bulls (at approximately 5 to 14 months) is employed, wherein the tool of (c) provides a substantially stress-free ligation technique. Moreover, the meat produced from the cattle processed using the present invention has superior cutability characteristics. | ||||||

| The invention relates to fire-extinguishing technology, in particular a process for producing aerosol-forming pyrotechnical compositions for extinguishing fires. The process includes the steps of mixing powdery combustible binder, oxidizing agent and dicyandiamide. The combustible binder is a polycondensate of formaldehyde and a organic compound, of a fraction from 70 to 120 &mgr;m. The oxidizing agent is an alkali nitrate of a fraction from 15 to 25 &mgr;m. The dicyandiamide is a fraction from 40 to 80 &mgr;m. Subsequently, there is added to the above, respective fractions of the combustible binder of 10 to 25 &mgr;m of the oxidizing agent of 1 to 7 &mgr;m and of the dicyandiamide of 7 to 15 &mgr;m. The weight ratios of the fractions of combustible binder, oxidizing agent and dicyandiamide are 70:30, 25:75 and 80:20. The resulting mixture is molded while the content of the components is 9 to 20 weight percent dicyandiamide, 6 to 14 weight percent combustible binder, and the balance weight percent oxidizing agent. | ||||||
| 143 | Compound lever activated elastomeric band castration tool | US15337 | 1998-01-29 | US5902309A | 1999-05-11 | LeGrande D. Wadsworth |
| A tool and method for continuous elastomeric band ligation type castration of larger sexually mature animals with an elastic band that must be enlarged by stretching for placement provides an elongate body having a handle at a first rearward end to aid manipulation and an elastic band supporting yoke at a second forward end. The band supporting yoke provides spaced forwardly extending legs for releasable support of the elastic band at two spaced points. Band stretching mechanism carried by the body provides an elongate stretching rod that releasably interconnects one course of the elastic band carried by the yoke at a third point between the two yoke support points to stretch the band rearwardly responsive to motion of an associated compound lever mechanism to enlarge the medial orifice defined by the elastic band sufficiently to allow the band to pass over the scrotal pouch and contained testicular structure of a large animal. The elastic band is stretched rearwardly through an annular support carrying a fastening clip that is deformed about the band to maintain tension in the band portion extending about the neck of the animal scrotal pouch. Release mechanism disassociates the tool from the elastic band to leave the tensioned band portion about the neck of the animal scrotal pouch at the ligation site. | ||||||
| 144 | Ligature tool to tension and fasten clips on surgical tubing | US149623 | 1993-11-09 | US5425736A | 1995-06-20 | LeGrand D. Wadsworth |
| A ligature tool, of the type having a handle carrying an elongate body defining a fastening clip chamber in its forward part with ligature tubing holding and tensioning means carried on the body, provides improved crimping and tubing holding means. The crimping element provides a single pivotally mounted crimping dog that contacts a slit portion of an annular ligation tube clip carried in the fastening clip chamber and is movable into that chamber to crimp the sides defining the slit toward the adjacent inner surfaces of the annular clip body to fasten ligation material therebetween. The tubing holding means provide a body supporting similar laterally opposed tubing holders each having a headed vertical post about which the end portion of tubing is wound under tension before placement in an adjacent wedge-shaped slot for releasable fastening. The tubing holding body also provides tubing cutting structure. | ||||||
| 145 | Instrument for ligation and castration | US718508 | 1991-06-20 | US5190560A | 1993-03-02 | John B. Woods; Wayne Porter |
| An instrument for castration by ligating and severing blood and seminal vessels. A pistol-shaped tool comprises a hollow body forming a barrel and a hand grip. A yoke pivotally mounted in the cavity of the grip is pivotally connected to a trigger, ligating means and severing means. The vessel to be ligated and severed is positioned in a slotted area at the muzzle of the barrel. The initial pulling of the trigger toward the grip causes blade guards connected to the severing means to surround the vessel or vessels. Further movement of the trigger toward the grip actuates the ligating means to push a ligature from a ligature container and around the vessels. The ligature is forced through ligature compressors which press the locking ligature onto the vessels. Final movement of the trigger toward the grip moves the severing means to force a blade through the vessels. | ||||||
| 146 | Clip for elastomeric ligation tubing | US886141 | 1992-05-21 | US5188637A | 1993-02-23 | Legrand D. Wadsworth |
| A metallic clip, to fasten two ends of latex surgical tubing under tension when used as a ligation element especially as in the castration of animals, provides a cylindrical tubular element defining an axially aligned slit through its periphery, with each side portion adjacent the slit defining angulated slots extending spacedly inwardly from a first end of the clip in a diverging fashion, to receive tubing ends. The clip defines an outwardly extending alignment protuberance inwardly from the second end of the clip in a position diametrically opposed to the peripheral slit. For use two latex surgical tubes are passed through the clip channel and one end portion of the tube is inserted in each slot. After tensioning the tubing, the clip is mechanically deformed, preferably by a tool created for such purpose, to bend each body portion between the slot and the slit inwardly to fasten each adjacent tube portion between that clip portion and the opposite side wall of the clip. | ||||||
| 147 | Electric emasculator and method for castrating | US591064 | 1984-03-19 | US4587968A | 1986-05-13 | David R. Price |
| An electric emasculator for castrating a bull calf or the like having a first scissor member pivotally connected to a second scissor member. The second scissor member has a structure defining a bifurcated fork with a pair of parallel upper edges. A heating element is positioned along one of the parallel upper edges to cauterize as an incident to the severing operation and assists in the blood coagulation to prevent the flow of blood and closure of blood vessels in the area of amputation. A method for castrating the bull calf includes registering the end of an arcuate-L shaped hook of the first scissor member with the bottom structure of the bifurcated fork simultaneously to lodging a crushing block, that is integrally bound to the first scissor member, against the top of a second cutting edge. The method additionally comprises cauterizing the severed tissue therebetween as an incident to the severing operation by releasing and conducting electricity to the heating element in order to assist in the blood coagulation to prevent the flow of blood and closure of blood vessels in the area of amputation. | ||||||

| This invention relates to a surgical tool for use in removing the ovaries from large animals that is characterized by a pair of telescoped tubes, the inner tube of the pair terminating in a pointed end movable from a retracted position recessed inside the outer to an extended position projecting therebeyond. The inner tube is also rotatable within the outer tube so as to bring a pair of oval-shaped openings into registry with one another, so as to receive the ovaries to be removed one at a time. These openings have knife-edged margins effective to excise the ovary inside the tubes upon rotation of the inner tube within the outer. A plunger is also housed within the inner tube effective upon extension from a normally retracted position to push an excised ovary into a storage area behind the point of the inner tube thus clearing the opening therein to receive the second one. The invention also encompasses the novel method for removing the ovaries from large animals which comprises inserting the tool into the vagina, extending the pointed end of the inner tube and puncturing the vaginal wall therewith, retracting the point and inserting the tool into the abdomen with the openings therein in registry with one another, manipulating the first of the two ovaries per rectum into the openings and rotating the inner tube relative to the outer to excise same, and removing the tool. | ||||||
