Title: Navigation system for motor cars, lorries, etc. - has electronic compass, filter unit and data processing unit
IPC: G01C22/02
Filed: 1985-08-28
Abstract: The navigation system includes an electronic compass (2) of a conventional flux gate sensor type.

Date Aug. 18, 1994Injection mold comprising at least two mold sections (2, 3) between which a mold cavity is delimited. One (3) of the mold sections is provided with an ejector (42) for removing the product after injection molding. The other mold section (2) is provided with a gate (5). To enable the solidified sprue to be separated from the molded article, a bush (8) is also present in which the gate (6) likewise extends. This bush (8) is constructed to be movable to a limited extent relative to the mold section (2) in which the other part (5) of the gate is made. As a result the sprue can be pulled away from the article in a guaranteed manner. The movement of the bush (8) is controlled by a jack (16, 17). Consequently, controlled breaking of the sprue is possible and the advantage arises that, by releasing the pressure on the jack (16, 17), no force has to be overcome when the mold is closed.

Title: Method of phase-syncronising a transit exchange in a digital telecommunication network
IPC: H04M/
Filed: 1983-07-26
Abstract: The phase-detector (2) generates a signal (p) proportional to the difference between the links and the exchange oscillator. This signal is differentiated (3). The differentiated values are compared with a limiting value, positive or negative, in a respective comparator (7a,7b). If the limit is exceeded, a respective contact is closed (8a,8b) to connect a compensation voltage (delta t) to an addition circuit (9) which receives also the differentiated signal. The signals from the appts. (1) of each transit exchange (F2-F4) are fed to a summing circuit (10), the output of which is fed to an integrator (11) with a memory (12) and an adding circuit (13). The output signal controls the frequency of the oscillator (15) through a regulator (14). The risk of the network swinging, because of phase jumps, is reduced by the process of differentiation, signal compensation and integration, which eliminates the results of the phase jump.
