Title: Device for measurement of angular velocity of a rotating body
Inventor: STEFFES HELMUT
IPC: G01P3/488
Filed: 1987-02-11
Abstract: A device for measurement of angular velocity of a rotating body comprises a transducer (1) composed of a core (2), an exciting winding (4) and a measuring winding (3). Said transducer (1) is arranged at the periphery of a toothed disc (10) co-rotating with the rotating body. The current flowing through the exciting winding (4) and thus the intensity of the magnetic field in the air gap between the transducer (1) and the toothed disc (10) is controlled in dependence upon the magnitude of the voltage induced in the winding (3) in such a fashion that, in the event of a standstill or a low angular velocity, maximum current flows, which current reduces when the angular velocity increases. In this way the induced signal strength is rendered less variable. An evaluation circuit is also connected to winding (3), the frequency of the signal voltage being a measure of the speed of disc (10). The arrangement may be used for measuring wheel speed in an anti-lock braking system. <IMAGE>

Title: Door latch
Inventor: SUM HO KWOK
IPC: E05B63/06
Filed: 1987-10-14
Abstract: The latch has a handle 21 for rotating a shaft 19 and a curved blade 20 to cause sliding of a first member 7 which retracts a bolt 8 into a housing 1. The curved blade 20 may act directly on the first member 7, thus giving a distance (L1, Figure 1) between the centre line of shaft 19/blade 20 and an end face 21 or the curved blade 20 may act indirectly on the first member via a removable adaptor piece 30 (see Figure 4). In the latter case, the centre line is positioned closer to the end face 2' thereby reducing the distance from L1 to L2. Thus, when the door latch is being fitted to a door, the spacing between the centre line and the side face of the door may be chosen to be either one of two different values (L1 or L2). The adaptor piece 30 has a pair of recesses (31, Figure 5) which locate the adaptor piece 30 through engagement with bosses 40 and shaft 19 and blade 20 project through a central opening 32 in the adaptor piece. <IMAGE>
