Abstract: A fruit collector for hillside orchards, which includes a channel spaced chute formed of inflated tubes, the two sides of the chute being joined by a cross web having a series of fruit receiving openings approximately the spacing between rows of trees, the chute being laid downhill between sloping rows of trees. In a first embodiment, the openings are formed by U-shaped slits to receive fruit, and retarding flaps extend into the chute to retard movement of the fruit. In a second embodiment, the cross web is tubular, but non-inflated, and receives a series of longitudinally extensible and retractable ribbons protruding from the upper margins of the openings and extending into the chute between the openings; the strips serve to retard movement of the fruit and may be in axially overlapping relation, and adjustable to change their retarding effect thereby to compensate for different degrees of slope.

Abstract: A multiple positionable hand tool holder, primarily intended to receive a tool for perforating an irrigation tube for the purpose of installing a drip emitter having a tubular inlet stem; the tool holder having an essentially oval configuration with a peripheral rim and a radial stem provided with a punch or the like, and capable of being held in a multiplicity of positions to permit frequent change in the manner in which the tool holder is held by the user's hand thereby materially reducing fatigue.Between use of the tool to perforate, the tool holder may be retained at the base ends of one or two fingers, permitting the fingers and thumb to pick up and manipulate a drip emitter so as to insert its inlet stem into the irrigation tube. By continued retension of the tool holder in the user's hand, the chance of losing or misplacing the tool holder in the course of installation of drip emitters is materially reduced.

Abstract: An injector for molding machine capable of operation with a simple mold having few cavities at a total cycle of as little as one to five seconds, thereby accomplishing high speed production with a minimum number of mold cavities; the injector having a nozzle structure so arranged as to minimize heat transfer to the mold whereby the mold may be maintained at a temperature to effect rapid cooling and ejection of the molded part, while the molding material in the nozzle is maintained in a fluid condition; the rapid cycle of operation serving to maintain the desired nozzle temperature, also.

Abstract: An irrigation deterrent tube, particularly adapted for drip or trickle irrigation, the tube having, normally, a flat configuration when free of internal pressure, and expansible to an essentially cylindrical configuration, when pressurized, the tube having laterally projecting webs which tend to be the first to be bitten by a rodent while exploring the presence of the irrigation tube; the lateral margins of the webs may be enlarged to contain a concentration of a deterrent or toxic material. In one embodiment, the tube and webs form a single extrusion, in other embodiments, the tube and webs may be separately extruded and subsequently joined together.

Abstract: A continuous flow tube containing a series of emitters arranged to discharge through a wall of the flow tube, each emitter forming a flush flow passage collapsible to form a drip flow passage at a preselected low flow tube pressure; the emitters having side walls of such area with respect to the area of the flow tube, that when exposed transversely to initial flow through the flow tube the emitters form externally a series of flow restricting valves which rapidly raise the flow line pressure to a value at which drip flow occurs, thereby minimizing the number of emitters undergoing flush flow.One embodiment of the emitter is adapted to be installed by forcing the emitter into the flow tube from the exterior thereof. Another embodiment utilizes a flow tube initially in the form of a web which receives the emitters and is then rolled into a tube with the margins of the web circumferentially overlapped and bonded.
