Patent DE-2709177-A1 (DE)
Inventor: KOCH WILHELM ING GRAD
IPC: B61C9/44
Filed: 1977-03-03
Abstract: Newly developed locomotives are equipped with rotary current short circuit rotor travel motors which are supplied via converters from the contact line fed with single-phase alternating current. In converters with variable frequency, when realised in practice, a certain harmonic content in the motor current cannot be avoided when taking into account expenditure, which harmonic content leads to oscillating moments of the drive motor. These oscillating moments lead, in the case of a drive via a hollow cardan shaft with articulated lever couplings arranged on both sides to axial vibrations of the cardan shaft. These vibrations are avoided in that an additional rubber ring spring coupling (25) is arranged at least parallel to one of the articulated lever couplings (21 to 23). <IMAGE>

Title: Automatic camera flash exposure setting - uses distance setting to adjust internal linkages and select correct aperture on electromagnetically-controlled shutter and aperture
Inventor: ETTISCHER HELMUT
IPC: G03B7/16
Filed: 1977-05-24
Abstract: Photographic camera has an automatic exposure control which adjusts the aperture and shutter speed setting by using a single electromagnet. A focussing adjustment is coupled to the aperture for correct flash exposure. The flash unit is inserted in a socket and operates distance setting mechanisms and 'flash' warning lights. The aperture setting is operated by a setting blade linked to an anchor lever and the electromagnet. By linking aperture and distance mechanisms the aperture can be adjusted for correct exposure by flash. The camera shutter release control is also linked to the focus and aperture and additionally operates the shutter blades. Linkage of shutter release to aperture and focus is effected by the rocking armature between release control bar and electromagnet contacts, to cause the correct aperture blade to move into position.

Title: Determining elasticity constant of automobile tyre - by calculation from forces exerted as tyre moves a measured distance
Inventor: GRAHAM ROBERT PETER SAMUEL
IPC: G01M17/02
Filed: 1979-03-01
Abstract: In the first phase of the measurement of the elasticity constant of an automobile tyre, a wheel with its tyre is lifted from a weighing machine. The lifting is effected by a fork or other suitable arrangement linked to a jacking device. In the second phase the tyre is lowered on to the weighing plate and means are provided of recording the force exerted by the tyre against the plate. Means are also provided by which a first value (P1) and a second value (P2) of the force which the wheel exerts against the weighing machine, can be recorded, as the wheel passes two points spaced apart at a distance (a). The elasticity constant of the tyre is then calculated by a microprocessor according to the formula K=(P2-P1)/a. The device is for use with the testing of the shock damping function of an automobile. The measurement of the damping function is to a certain degree dependent upon the elasticity constant of the tyre, and this simple device determines this contant.
