Title: Friction clutch unit
IPC: F16D13/46
Filed: 1981-04-03
Abstract: A friction clutch unit with two coaxial friction clutches the first of which has a first friction disc driven by the crankshaft of an internal combustion engine and disposed between an axially fixed and an axially movable pressure plate. The second clutch has a second friction disc which drives the input shaft of a change-speed transmission in the vehicle which embodies the engine and is disposed between an axially movable pressure plate and an axially fixed pressure plate. The axially fixed pressure plates of the two clutches are connected to each other by a rotary housing which defines a fulcrum for a common dished spring having an outer region bearing against projections provided on the axially movable pressure plate of the first clutch and an inner region bearing against projections provided on the axially movable pressure plate of the second clutch in engaged condition of the clutches. The bias of the common spring upon the axially movable pressure plate of the first clutch is assisted by a dished second spring which bears against the outer region of the common spring and reacts against an abutment forming part of the housing. The second clutch is disengaged ahead of the first clutch and the first clutch is reengaged ahead of the second clutch by an axially movable shifting plate which is connected with the common spring radially inwardly of the inner region of the common spring. The outer region of the common spring pivots relative to the axially movable pressure plate of the first clutch during disengagement of the second clutch and the common spring pivots relative to the fulcrum during disengagement of the first clutch.

IPC: B21D43/05
Filed: 1981-08-28
Abstract: A power press arrangement including a series of power presses (11) operating synchronously with intervening loader (21), unloader (22) and conveyor mechanisms (23). The various intervening mechanisms are controlled in synchronism with the presses (11) in the press line through numerical control systems which are co-ordinated with press slide positions. For the loader and unloader mechanism (21 and 22), for each axis thereof, a discrete number of desired position locations are loaded into an associated press control memory, and the data is processed into a derived motion table for each loader and unloader axis and followed to effect axis motion in co-ordination with press slide position. During operation of each press, the associated control system continuously derives motion control parameters for the loader and unloader axes based upon the tubular values. Other peripheral devices such as conveyors and turnover mechanisms are also operated by the control systems.

Title: Doppler radar velocity measurement apparatus.
IPC: H01Q19/06
Filed: 1984-04-05
Abstract: Doppler radar apparatus for use in a velocity measuring system for farm tractors and the like. The apparatus includes a dual mode conical horn having a flare angle substantially in excess of 12.5 DEG , and a dielectric lens formed of a glass filled polymer. The doppler output signal provided by the RF transceiver associated with the dual mode horn is high pass filtered to remove low frequency signals therefrom. The horn is mounted in such a way that it is isolated from mechanical vibrations which would induce doppler signal frequencies in excess of the cutoff frequency of the high pass filter. Moreover, the horn assembly (which is aluminum) and a steel housing assembly are coupled together in such a way that thermal expansion and contraction will not loosen the friction fit between the two assemblies. The two assemblies are held together by a single, large diameter annular locking ring.
