Abstract: Arranged in the housing (1) of the lock latch is a circuit (17) of an access monitoring device with two switches (18, 19) connected in series. The first switch (18) is opened in response to the displacement of a slide (11) by means of an electromagnet (15) or by means of a key-actuated cylinder lock (16) during entry from the outside. When the door is opened as a result of key actuation, the access monitoring device does not detect authorised access and triggers the alarm. So that exit from inside takes place without the alarm being triggered, when the lock latch (3) is retracted by means of the pusher located on the inside the second switch (19) is closed, with the result that a signal for authorised exit is transmitted to the access monitoring device. By means of this arrangement, unauthorised access from outside cannot take place unnoticed via the key-actuated cylinder lock (16). <IMAGE>

IPC: G11B19/28
Filed: 1988-04-05
Abstract: A read apparatus for reading a record carrier (1) having a concentric track pattern comprises a scanning device (2, 3) for reading the information, and a separator circuit (4) for extracting a periodic synchro­nising signal (Ps) from the information read. By means of a servo system, which  inter   alia  includes a drive motor (9) for driving the disc 1 and a control circuit (5), the rotational speed of the disc is controlled so as to maintain the periodic synchronising signal (Ps) in synchronism with a reference signal (Pr). The circuit (9a) rejects those signal components in the control signal (U) for the motor (9) which are caused by an eccentric position of the centre of rotation of the disc relative to the track pattern. This prevents these signal components from causing an unnecessary dissipation of electric power in the motor, yielding a substantial improvement in motor efficiency.

Inventor: MICHIE MICHAEL M
IPC: C03B37/018
Filed: 1988-07-26
Abstract: An improved multimode optical fiber having substantially higher bandwidth and lower loss is made by varying the volume of the silica which is deposited in passes of a torch assembly (41) along a substrate tube (31) to form a preform tube which is collapsed to provide a preform (80) from which the optical fiber is drawn. As a result, the thicknesses of the outermost deposited glassy layers in the preform tube are greater and those of the innermost layers are less than those of layers in a preform tube made by prior art MCVD processes. This causes the difference in the index of refraction across each glassy layer to be reduced thereby enhancing the bandwidth and reducing the loss of the drawn optical fiber over those properties of optical fiber drawn from preforms made by prior art MCVD processes. Inasmuch as the inventive process also allows a higher deposition rate than before, it may be used to produce single-mode optical fiber at lower costs than before achieved.
