| 241 | Low profile, current-driven relay for integrated circuit tester | US09491080 | 2000-01-20 | US06329892B1 | 2001-12-11 | Paul Dana Wohlfarth; Robert R. Hale; Travis Scott Ellis |
| A relay includes contacts residing within a glass tube. A coil surrounding the tube and a switch are connected in parallel between two terminals of the relay. A current source supplies a current to the coil and switch. When the switch is open, substantially all of the current passes through the coil and the coil produces a sufficient amount of magnetic flux to close the relay's contacts. When the switch closes, it shunts a sufficient amount of the current away from the coil to reduce the magnetic flux it produces below the level needed to keep the contacts closed. The current source is sized so that the coil requires relatively few turns, thereby allowing the relay to be relatively thin. The coil is formed by a conductor embedded in an insulating substrate surrounding the tube. | ||||||

| 248 | Electromagnetic relay and method for assembling the same | US930023 | 1992-08-21 | US5289144A | 1994-02-22 | Shangshyan Liao |
| The relay comprises a flat base, a motor unit mounted on the base, an armature arranged on one end of the motor unit to actuate a contact arrangement fastened on the base at the other end of the motor unit. The movement of the armature upon energization or de-energization of the motor unit is transferred to the contact arrangement by means of a pusher arranged above the motor unit. The pusher is clamped to the armature by means of a multi-functional retainer spring which serves also for fastening the armature to a frame and for biasing the armature into its rest position. The motor unit is inserted with terminals and bobbin posts into oblong holes of the base so as to be displaceable in an actuating direction for adjusting a contact gap or overtravel during assembly of the relay and before securing the motor unit to the base. | ||||||

| A relay comprising an electromagnetic coil wound on an insulating bobbin, the central cavity of which encloses a central spring-biased contact actuated by a magnetic armature in response to energization of the coil, to make or break contact with one or more fixed contacts also enclosed. A U-shaped member and a heel plate, both of highly magnetically permeable material, surround the coil and complete the magnetic circuit for flux generated by the coil. The magnetic armature is constructed and arranged such that it is accessible from the exterior of the enclosed relay to adjust the position of the spring-biased contact of the relay after it is assembled to conform with the desired level of voltage required to actuate the relay. | ||||||
| 250 | Method for (prepolarizing and centering) operating a piezoceramic power switching device | US383316 | 1989-07-20 | USRE33587E | 1991-05-14 | John D. Harnden, Jr.; William P. Kornrumpf; George A. Farrall |
| This application describes a number of novel advanced piezoelectric ceramic power switching devices which are mounted within protective gastight enclosures that are either evacuated to a high degree of vacuum or filled with an inert gas protective atmosphere. The devices thus constructed are capable of operating over a range of load voltages extending from about 100 volts to 5000 volts or more with corresponding currents of from a few amperes to hundreds of amperes and wherein it is possible to provide a number of such structures in a single common protective gastight enclosure. For certain circuit applications the devices thus constructed have unpoled portions on which are mounted either passive circuit components such as resistors, capacitors and the like or active semiconductor devices all interconnected in circuit relationship with each other and the switching devices by using printed circuit or integrated circuit fabrication techniques. In these devices, stray circuit impedances whether capacitive, inductive or resistive in nature can be reduced to an absolute minimum by appropriate designs. Such complementary circuit components and active semiconductor devices can be, if desired, mounted within the common protective enclosures in close proximity to the piezoceramic switching devices to which they are connected, or alternatively may be mounted exteriorly of the protective enclosures. | ||||||

| An electrical device, which preferably forms a plug-in relay unit, includes a terminal board assembly most advantageously formed by a pair of insulating plates made of thermoplastic material and between which are clamped the intermediate laterally extending portions of terminal blade members having outer portions projecting transversely beyond the outermost plate constituting a base plate and transversely innermost portions projecting beyond the innermost plate constituting a clamp plate. One or more of the terminal blade members carry stationary contacts on the inner ends thereof. The insulating plates are held secured together and a bobbin assembly having thermoplastic pins are passed through apertures in the base assembly and ultrasonically vibrated to weld the same to the walls of the apertures. A core and heel piece sub-assembly is initially mounted for progressive movement upon the bobbin assembly and anchored in place in a given position thereon where the core section thereof projects beyond a core-receiving aperture of the bobbin assembly a given predetermined distance. The core and heel piece sub-assembly includes a core section adjustably mounted in a predetermined position upon a heel piece section before it is mounted on the bobbin assembly. An armature with a movable contact is pivotally mounted on the end of the heel piece section for movement toward and away from the projecting core section. | ||||||
| 253 | Tool and method for installing flexible tubing in a multi-capsule reed relay switching assembly | US947978 | 1978-10-02 | US4186482A | 1980-02-05 | James V. Koppensteiner; Khaja M. Jameel; Charles K. Kubik; George Len |
| A tool and method for installing a flexible tube between two or more glass encapsulated reed switches of a multi-capsule reed relay switching assembly. The tool includes a rectangular horizontally oriented insertion member with a billhook raised at one end. The rectangular insertion member is arranged to narrow the tubing into a slightly egg-shaped configuration when the tubing is fitted over it. The billhook is adapted to partially penetrate an inside wall of the tubing allowing the tool to essentially drag the tubing into place. During installation the tubing collapses against the insertion member reducing the amount of initial interference between the tubing and the glass reed capsules. | ||||||
