Patent EP-0421063-A2 (EP)
Inventor: ALLENBERG BERND
IPC: G01G13/24
Filed: 1990-07-14
Abstract: In a process and an apparatus for improving the metering accuracy of a differential metering balance connected to a controller and to an estimator, there is an evaluation device which minimises at least two stochastic disturbance variables by means of a model computation. For this, the evaluation device contains an analyser circuit which scans an estimated-value signal for a specific period of time and which forms the power-density spectrum of this. Those frequencies which exceed the value of an especially high power density are determined from the power-density spectrum in an identifying circuit. These frequencies serve, in a correcting circuit to form a frequency spectrum which corresponds to the actual stochastic disturbances. In a comparator circuit, this spectrum is compared with a model spectrum calculated by a model-computing circuit, and that model coming nearest to the actual spectrum is determined. A controller-setting circuit then determines from the model spectrum obtained the spectrum which corresponds to that of the pick-up disturbances and of the bulk-density disturbances. The controller-setting circuit forms from this a signal which serves for optimising the controller.

Abstract: 2.1 In the transmission of digital signals it is frequently necessary to use pulse stuffing methods. PLL arrangements are necessary in the desynchroniser for smoothing the clock of the recovered signal. 2.2 An arrangement is specified in which an analog PLL arrangement, which needs much space and power, can be omitted. The arrangement exhibits a digital phase-locked loop which consists of a digital filter (F) and a pulse density modulator (PDM) which makes the stuffing decision in dependence on the output value of the digital filter (F). An adder (AD) is provided in which the measure of the mean loading level of the elastic memory of the synchroniser, which was transmitted in the frame of the second digital signal (A) and the measure of the mean loading level of the elastic memory (ES') of the arrangement are added together. 2.3 Transmission of digital signals with pulse stuffing. <IMAGE>

Abstract: In an apparatus (1) for recording information signals (S) on a recording carrier (3) in tape form, an "information signal-controlled recording" operating mode can be switched on. For driving the recording carrier (3), the apparatus (1) has a motor (11) and a drive mechanism (12), which can be driven by the motor (11) and has two non- positively interacting drive parts (15, 16), which are constantly pressed against each other when the "information signal-controlled recording" operating mode is switched on, the motor (11) being switched on by a motor control circuit (43) if an information signal occurs, which is determined by an information signal detector (40), and is switched off after a time delay by the motor control circuit (43) if no information signal (S) occurs. The motor control circuit (43) has a pulse generating device (G) which, with the "information signal-controlled recording" operating mode switched on but no occurrence of information signals (S) for a considerable time, repeatedly generates at predetermined time intervals (T2) short control signal pulses (M1), by which the motor (11) is switched on for a short time, as a result of which the two drive parts (15, 16) are brought one after the other into always different relative positions with respect to each other.

Abstract: A tubular wire housing (10) has at one end, a ring of notches (32), each communicating with a slot (36) for receiving a slotted plate wire connecting portion (64) of a respective contact element (42) of a mating contact housing (12). The wire housing (10) is formed with external half-channels (28). The contact housing (12) has a hood (48) formed with internal half-channels (58). End portions of wires (W) of a shielded cable (C) are inserted through the wire housing (10) and are dressed into the notches (32). The housings (10 and 12) are then mated by capturing the wire housing (10) in the mouth of the hood (48), trimming the radially projecting parts of the wire end portions and then pressing the housings (10 and 12) into full mating relationship. During this operation, the trimmed ends (SP) of the wire end portions become fully enclosed in the half-channels (28 and 58). High contact density is achieved by offsetting the wire connecting portions (64) for reception in corresponding ones of the slots (36) so that some of the contact elements (42) can be positioned radially inwardly of others.
