  • Patent number: 5582287
    Abstract: A zero-pressure accumulating conveyor including a bed defined by rotatable rollers mounted in parallel sidewalls and powered by an endless drive chain. Pneumatic actuators lift the drive chain into engagement with the rollers to empower same. Sensor rollers divide the bed into distinct zones. Sensor rollers are retained in operative position relative to the conveyor bed by unique sensor brackets. A primary sensor roller bracket includes a bore with a piston movable there within; the cooperating secondary sensor roller bracket is spring biased in a first direction. Valves, and pneumatic circuitry controlled by such valves, extend along the length of the conveyor. Such valves are operated by the primary sensor roller brackets to regulate the flow of air pressure into the bores of the brackets and into the actuators. The actuators, when the pressure therein is bled-off, allow the chain in a particular zone to drop out of contact with the rotatable rollers.

  • Patent number: 5532298
    Abstract: A degradable agricultural ground cover which is composed of high density polyethylene polymer fiber and cellulose pulp which is 100% photo and biodegradable for use in weed control and moisture retention in soil. The unique agricultural mat or cover lasts 8-12 weeks before serious photo and biodegradability occurs, while allowing crop plants sufficient time to mature and produce. The sheet totally disappears with plowing and tilling, becoming a soil extender until complete degradation occurs.

  • Patent number: 5481965
    Abstract: A rack and screen assembly for converting gas grilles into charcoal and/or wood burning stations. The assembly is fabricated from high temperature stainless steel, so that the assembly, when heated to its cooking temperature, retains such elevated temperature for an extended period of time. The rack includes an open frame with runner legs at its lower end, that sit atop the cylindrical tubes of conventional gas grilles. Braces extend transversely across the open frame to reinforce same, and ledges are defined at the upper ends of the open frame. The perforated metal screen is inserted into the upper end of the frame until the screen rests upon the ledges. When the screen is damaged, or wears out, the damaged screen is lifted out of the frame and replaced, manually, in a simple fashion and without resort to manual tools.

  • Patent number: 5287685
    Abstract: An apparatus is disclosed for harvesting seed which includes a frame and a housing defining a seed box and having a rotary brush mounted on a forward portion thereof which is connected to link bars which are in turn connected to the frame. Corresponding pairs of link bars are attached between the frame and housing on opposite sides of the apparatus, the link bars on each side being substantially parallel to each other. Means are provided for varying the angle of the link bars to the frame, the link bars operationally functioning as a parallelogram to raise or lower the housing at a constant angle relative to the frame. A draw bar is pivotably connected to the front of the frame and tilt angle adjustment means are provided to vary the angle between the frame and the draw bar thereby providing an independent means for varying the angle of attack of the rotary brush to the plants from which seed is being collected.

  • Patent number: 5052138
    Abstract: Several embodiments of ammunition supply indicating systems for firearms are disclosed. Each system (1) counts, either automatically or manually, the number of rounds in a magazine introduced into the firearm, (2) detects the movement of a reciprocally movable slide in the firearm to increment a count of "one" for the round entering the firing chamber, and (3) electronically combines the two digits, and (4) displays same on a display panel. The display panel is situated in a thin housing secured to the firearm along the line of sight of the user. A running total of the number of rounds remaining in the firearm is visible to the user. Slide movement may be detected by magnetic, mechanical, optical, or electrical devices, while the number of rounds remaining in the magazine may be monitored by position switches operated by the follower within the magazine.
