| 161 | Weed control in joints of concrete block and other paving stone | US10572246 | 2004-09-17 | US09011855B2 | 2015-04-21 | Jens Sønderberg Frederiksen; Poul Konrad Beck; Steffen Birk Hvorslev |
| The present weed reducing material reduces the necessary weed control work by making joint filling sand a hostile substrate for plant and fungus growth by using an environmentally acceptable slow release mineral additive. The additive, having similar grain size distribution, mechanical and rheological properties, forms an integral part of the joint filling sand. The specific gravity of the additive is lower than quartz sand imparting a tendency for the additive to migrate towards the top part of the joint. The additive leads to pore waters rich in sodium and at high pH, both qualities being maintained over long periods. The mixture of additive and sand is handled and applied using conventional laying techniques and equipment, observing usual precautions for mortar or cement mixes with sand. In the environment, reaction with CO2 in the air or in the soil porosity inactivates the causticity, yielding harmless carbonate salts. | ||||||

| The present invention relates to a device particularly suitable for grooming/shaping various snow terrain features used by recreational snowboarders and/or skiers and includes an adjustable arm assembly (2) attachable at one end to a suitable vehicle and being capable of deployment substantially orthogonally to the direction of movement of said vehicle; said arm being substantially elongated and including two or more articulately connected sections (5, 6, 7) and one or more actuator means (11, 12, 13) capable of changing the orientation at least two of said sections (5, 6, 7) with respect to each other. The invention is also suitable as a means of shaping embankments or features of earth, soil, sand and so forth or for cutting grass or similar undergrowth. | ||||||

| 164 | Vehicle mounted fluid delivery system with retractable arm | US149358 | 1998-09-08 | US6021959A | 2000-02-08 | John M. Mayfield, Jr.; Ted E. Mayfield; Mark L. Natalizia |
| Mobile fluid delivery systems and methods are disclosed. The disclosed embodiments are particularly useful for spraying herbicides on a roadside shoulder. The systems include nozzles mounted upon a movable arm extending from a vehicle. A sensor mounted upon the vehicle detects objects which the extended arm is approaching, such as telephone or other utility poles on the side of the road. The sensor signals a control unit, which directs retraction of the movable arm to avoid collision with the object, and extension of the arm after passing the object. In targeted fluid delivery, the control unit can direct forward fluid spray to the backside of the object as the extended arm approaches, lateral fluid spray as the arm passes the object, and rearward fluid spray to the front side of the object as the arm is extended after passing the object. The system can thus effectively douse the ground surrounding a utility pole, for example, with herbicide and reduce fire hazard. | ||||||
| 165 | Roadside spraying apparatus for minimizing drift | US393076 | 1989-08-09 | US5284297A | 1994-02-08 | Johnny L. Kubacak; Gerald C. Gebheim |
| An apparatus for roadside spraying of herbicides or other liquids in a manner which ensures uniform application of the herbicide without resorting to atomization of the sprayed liquid. The apparatus provides means for uniformly applying the herbicide in a plurality of swaths at different distances from the spraying apparatus. The apparatus uses a means for vibrationally altering the directions of the sprayed liquid streams to ensure uniform coverage. The direction altering means allows the amplitudes of the direction alterations to vary in accordance with the target distance of sprayed liquid stream. | ||||||
| 166 | Street cleaning and herbicide applicator apparatus | US619401 | 1990-11-29 | US5097560A | 1992-03-24 | Bobby C. Lawrence |
| An apparatus wherein a herbicide applicator spray organization is mounted to a self-propelled street cleaning vehicle. The vehicle includes a forward rotary brush and a rear rotary brush, the forward rotary brush and herbicide applicator spray head are mounted to a parallel link support framework. A storage tank delivers the herbicide fluid to the spray head through a pump and valve interconnection. | ||||||
| 167 | Growth-preventing web for ground covering | US629366 | 1990-12-18 | US5090154A | 1992-02-25 | Christian Jacob |
| A ground cover preventing vegetation growth has a polyethylene or polyurethane ground contacting foil and an asphalt/styrene-butadiene-styrene protective and adhesive layer on the foil. The adhesive layer contains 15 to 25% by weight of a meal-fine mineral filler and is applied to the foil in an amount of 1,750 to 2,250 g/m.sup.2. A stone granulate, e.g. of gravel, with a particle size of 2 to 5 millimeters is pressed into the asphalt/SBS layer in an amount of 3,500 to 5,000 g/m.sup.2. | ||||||
| 168 | Growth-preventing web for ground covering | US232608 | 1988-08-15 | US4896453A | 1990-01-30 | Christian Jacob |
| A strip of vegetation-growth-blocking material for use as a ground cover as a polyethylene foil on an upper surface of which a bituminous protective and adhesive layer is applied to block ultraviolet deterioration of the foil. Gravel or a like heavy bulk material is bonded by the adhesive to the foil and a reflective layer can be applied to the gravel layer. | ||||||
