Title: Lubricating Apparatus for Movable Machine Components Particularly for Agricultural Machines
IPC: A01F15/07
Filed: 1979-10-24
Abstract: Apparatus for lubricating drive elements, such as chains or the like, of machines which have at least one component movable by a hydraulic piston-cylinder unit, the component being actuated intermittently during the operation of the machine, wherein pressurised hydraulic oil supplied in operation by a hydraulic pump is fed not only to the hydraulic piston- cylinder unit 17 but also to an additional pump 22, which can be actuated by the oil and which drives lubricating oil to the lubricating points of the drive elements at each stroke of the pump. The apparatus is particularly intended for agricultural machines. The pump 22 comprises a single acting piston 27 biassed by springs 28, and a valve having a slidable sleeve 32 and a hexagonal member 35 movable in sleeve 32, whereby movement of piston 27 in direction A on pressurisation of the hydraulic system moves the valve in direction B to allow lubricating oil to pass into pipes 23, and return of the piston 27 when the hydraulic system is depressurised draws lubricant into pump chamber 37 from a lubricant reservoir 25 via feed pipe 24. <IMAGE>

Title: Handsfree telephone facility
Inventor: BAHR FRANK
IPC: H04B3/20
Filed: 1982-10-26
Abstract: A handsfree facility in a telephone arrangement has voice-controlled voice-direction identification whose control criteria for changing over from transmitting to receiving operation are derived from the voice voltage levels. A hybrid set (GA) has only one transformer with the transmitting and receiving directions interchanged relative to traditional voice circuits (Fig 2 not shown). Fixed level increases are also provided using only three damping values which are produced by two switching amplifiers (SV1, SV2) in the transmitting amplifier and two damping members (DG1, DG2) in the receiving amplifier. The voice levels are monitored by means of regulating amplifiers (RV1, RV2, RV3) and level detectors (PD1, PD2, PD3) and the change-overs between rest, transmitting and receiving operations, are effected by the level detectors, a subsequent gate circuit (G1-G3) locking the respective operating state. Change-overs from one type of operation into another are influenced by the time constants of the level detectors. <IMAGE>
