Title: Torque meter for rotating shaft - compensates for variation in coupling efficiency by using reference signal and chopper
Inventor: GINNS HASKELL
IPC: G01L3/10
Filed: 1975-02-24
Abstract: An excitation signal with periodic electrical markers is coupled to shaft mounted electronics for energizing a strain gauge bridge. An electronic switch is responsive to the periodic markers for alternately biasing and unbiasing the bridge to provide portions of torque representing output signal and torque plus reference representing output signal. The output signal is chopped at a second frequency and coupled back to instrumentation external of the shaft along with a signal representative of the phase of the chopping signal. The chopped output signal is synchronously detected and separated onto first and second paths, in accordance with the amplitude of the detected signal, which respectively represent strain gauge torque and reference. The ratio of the first signal to the difference between these signals represents the shaft torque compensated for variations in circuit performance and coupling efficiencies.
Patent DE-2511161-A1 (DE)
Title: Lorry for bulk-and itemised loads - has discharge funnels for bulk load underneath closed by hinged flaps
Inventor: KRONE BERNARD
IPC: B60P1/56
Filed: 1975-03-14
Abstract: The lorry has rigid sides (12) and a funnel shaped fitting (17) under the centre, between the wheels. The bottom of the funnel is closed off by a slider (23) and the top by hinged flaps (13, 14) which are hinged on either side of the slot above the funnel, to fold over each other and close off the funnel. The flaps lie flush with the floor of the vehicle so that it can be used for itemised loads. When bulk loads are to be carried the flaps are folded up to rest against the sides of the lorry and form sloping hopper sides for the funnel. This enables the bulk load to be completely discharged when the slider is pulled from the funnel. The vehicle is thus dual purpose and requires no complex tipping hydraulics which would also reduce the load carrying capacity.
Patent DE-2512338-A1 (DE)
Title: Circuit breaker light arc shifter - has swivelable flap with form holders abd backing support for plate
Inventor: POHL FELIX
IPC: H01H9/44
Filed: 1975-03-20
Abstract: The light are shifter is intended to increase the drive force exerted onto the light arc. At least one current conducting part of the electrode is made of ferromagnetic material, through which passes a magnetic field transversely to the direction of the light arc current at the foot point of the arc. The magnetic flux in the ferromagnetic part of the electrode moves first the light arc foot point and thus the entire light arc. The movement of the arc provides new current flow surfaces for the foot points and hence the arcing on the electrode surfaces is correspondingly reduced. The electrode is formed by an arc rail (2) whose end is formed of ferromagnetic material (4), secured to a magnetic yoke (12) with a coil (14), whose magnetic field moves the arc (10).
