Title: Trash emitting device for tractor-mounted blade
IPC: E02F3/76
Filed: 1969-05-05
Abstract: Material passing over the top of a dozen blade 27 mounted on vertically swingable arms 36 secured to either side of a vehicle 10 is prevented from passing beneath the vehicle body 11 to jam between the arms and the body by guard structures 51 so extending from the top of the blade to either side of the body as to bridge the space between the blade and the front of the body. Each structure consists of an upright, inverted U-shaped frame having a vertical leg 55 that extends in vertical continuation of the blade and an upwardly and rearwardly inclined light portion 52 and a rear leg secured to the associated lift arm to lie to the rear of the front end of the vehicle.

Title: Gear pump with balanced side sealing bushes
IPC: F04C15/00
Filed: 1972-03-14
Abstract: A gear pump for fluids, comprising gears which are laterally sealed by a counter pressure as a function of the delivery pressure. Sealing gaskets pertaining to the counter pressure have cylindrical seats. Counter pressure limiting rings independent of the wall and of the gear sealing bush, yet firmly held against the wall by a mechanical surface seal as a function of the difference in the diameters of the rings, thereby guaranteeing constant adhesion on the part of the contact surfaces between the rings and the wall while the pump is in operation. The rings are placed asymmetrically with respect to the surface of the sealing wall, so as to displace the center of gravity of the counter pressure towards the delivery side and make it coincide with the center of gravity of the internal pressure on the sealing wall.

Title: Trickle irrigation system
IPC: A01G25/02
Filed: 1973-07-21
Abstract: A trickle irrigation system which utilizes a series of irrigating valves and interconnecting tube valves, the irrigating valves assuming open, flushing conditions at pressures below a critical zone, and assuming a restricted or trickle condition at pressures above the critical zone whereas the tube valves assume a constructed flow or closed condition below the critical pressure zone and expand to full flow condition at pressures above the critical zone.
