Title: Agricultural seeder control system - blocks selected seed tubes by controlled shutter plates to leave non-planted furrows at specific lateral intervals
Inventor: KIRCHBERGER FRANZ
IPC: A01C7/08
Filed: 1980-09-03
Abstract: The control system allows selected parallel seed tubes to be blocked by hydraulic or electric shutter plates so that the corresponding furrows are left unseeded to provide circulation paths for subsequent plant treatment operations. The movement of the shutter plates is initiated by a counted sequence of changes in the control signal, where two different control signals are provided successively as a function of the measured distance along a furrow and the turning angle of the tractor steering wheels. Pref. a pulse generator is coupled to one of the wheels of the seeder supplying pulses to a counter operating as a distance recorder, with one of the control signals supplied each time a given distance has been traversed. The measurement of the turning angle of the tractor wheels may be effected via a switch allowing the second control signal to be provided each time they are turned through a given angle. The system ensures a constant spacing between the furrows left unplanted.

Abstract: Brake booster with increased stroke, which has a power piston arranged in a housing and actuated by the pressure differential on its opposing sides, a control piston, which includes a control valve for controlling the pressure differential and which is fitted coaxially into a central bore of the power piston so that it can move relative to the latter, and a reaction lever, on which an output element bears on an output section in its middle and which receives the output force of the power piston or the output force of the transmission mechanism as an input force on a first input section and a second input section, which are arranged on both sides of the output section, by means of which a greater stroke can be obtained on the output element than the stroke applied to an input element. Balls and a ball retainer are arranged between the control piston and the power piston. The ball is accommodated in a ball-receiving depression, which is formed on the outer circumference of the control piston with a bottom surface inclined forwards. The ball is moved by a steeply inclined drive face which is formed on the inner circumference of the power piston in order to move the ball retainer which strikes the first input section of the reaction lever. When the power piston has reached the foremost position a gently inclined surface formed on the rear side of the drive face touches the ball. In this state the reaction force of the reaction lever is partially transmitted to the control piston. <IMAGE>

Filed: 1981-03-07
Abstract: A remotely controlled automotive transmission shifting mechanism for effecting engagement of the respective gears with a force that varies in accordance with the gear selected. Pneumatic pressure from a compressed air storage tank is connected via a choke to a pneumatic actuating cylinder that effects gear engagement. A signal corresponding to the instantaneous pressure effective at the actuating cylinder is compared in an evaluating circuit with a reference value assigned to the gear selected. When the compared signals match, a solenoid valve is actuated to cut off further pressurization of the actuating cylinder and thereby modulate the gear actuating force in accordance with the gear selected. Following gear engagement, the gear actuating pressure is released.

Title: Lubricating device for pneumatically operated appliances
Inventor: FRIEDRICH WILLI
IPC: F16N7/32
Filed: 1981-03-19
Abstract: The invention relates to a device for passing lubricating and de-icing oil into the feed line of pneumatically operated appliances, such as pneumatic hammers or the like, with a line lubricator. Such a line lubricator (11) contains a lubricator head (10) for the connection of the feed line, a suction device, e.g. a Venturi tube, and a supply reservoir (17) fastened to the underside of the lubricator head (10). At the compressor system, the compressed air generated for the recovery of the injected lubricating and cooling oil is passed through an oil/compressed air reservoir (1) in which an essentially hollow-cylindrical filter element (6) is contained. Hitherto, devices independent of one another have been used for lubricating the pneumatically operated appliances and the compressor. The invention proposes to combine these devices in one unit. Such a combined device can be particularly advantageously configured by the supply reservoir (17) of the line lubricator (11) being arranged in the interior of the hollow-cylindrical filter element (6), the lubricator head (10) at the same time being designed as a lid for the pressure-tight closure of the oil/compressed air reservoir (1). <IMAGE>
