Patent DE-3012075-A1 (DE)
Title: Receiving circuit for data bits with jitter - has multiple pre-sampling circuit to select mid-bit clock pulse timing
Inventor: WINKELMANN HEINZ ING GRAD
IPC: H04L7/033
Filed: 1980-03-28
Abstract: The circuit is used in a data block system and employs a feedback loop between the bit phase and the clock pulse generator. In cases where the bit phase is unstable and produces jitter in the presence of noise, an arrangement is required in the detection system identifying the bit pulse midpoint reliably. This is achieved by presenting differentiated bit edges obtained from circuit group (8) to a divider-counter (10) having e.g. eight stages. At the count output of AND gates (9a-9h) there will be several output spikes if there is no jitter, only one output will show a spike. The result of the count is fed into eight counters (11a-11b) which count pulses in each time segment. The count is subsequently continued at the bit rate until the first output pulse (carry pulse) appears at the multiple OR-gate (13) and stops the control circuit (14). The line where the output appeared represents the bit mid period. The spatial position is decoded in a decoder (16), stored (in 17) and converted in a corresp. clock pulse in a pulse selector unit (18).

Patent DE-3105849-A1 (DE)
Title: Electronic control circuit
Inventor: MOORTGAT-PICK WALDEMAR DIPL PH
IPC: A63C9/088
Filed: 1981-02-18
Abstract: The object of the invention is to control the electromagnetic tripping of a safety ski binding, subject to particularly critical limit conditions, such as the minimum possible risk of failure, the elimination of temperature influences, low cost and negligible power consumption even in the activated state. In the case of the mechanically locked ski binding on which the invention is based, the deflection (which occurs in the event of an overload) of a retaining bolt controls two mechanical switches or reed contacts as a function of defined values of deflection in such a manner that the locking of the retaining bolt is released by an electromagnet at the desired moment. The supply to the electromagnet is effected by means of a power transistor which acts as a current amplifier and to whose base electrode a current pulse is applied, via the previously mentioned mechanical switch, from a storage capacitor, the amplitude of such current pulse being so high that the transistor is operated in the saturation state for a defined period of time.

Patent DE-3113443-A1 (DE)
Title: Washing or rinsing machine
Inventor: ELLERMANN HERMANN
IPC: D06F17/00
Filed: 1981-04-03
Abstract: The washing or rinsing machine is equipped with a washing or rinsing tub, with a circulating device for the heated water and with a housing preferably having a high degree of sealing relative to the atmosphere. So that a sudden pressure rise does not occur inside the machine when the circulating device is switched on, the circulating device is operated discontinuously in the start-up range by means of a control device, the respective switch-on time of the circulating device being small in relation to the subsequent intermission time, at least in the first part of the start-up range. As a result, an interval-like swirling of the cold air cushion located above the hot water together with hot water takes place, so that, with a rising temperature of the air, a steam/air mixture is obtained. As a result of the interval-like switch-ons of the circulating device in the start-up range preceding continuous operation, a sudden pressure rise inside the machine is prevented.

Inventor: GROEBER JOSEF
IPC: B29C65/00
Filed: 1981-07-07
Abstract: The invention relates to a device and a process for producing tubular articles from flexible textile tubes. The stretchable textile tube is drawn onto a mandrel (10, 31) by means of a drawing-off device (7, 27) and tensioned until the contact angle of the textile filaments (9, 29) corresponds to the desired contact angle on the mandrel. For the production of multilayer tubular articles, the flexible textile tube may be introduced into the free inner space of the mandrel (31) by means of a shell sleeve (34), as a result of which, with each working stroke of the shell sleeve, two additional textile layers are built up. These textile layers are enlarged to the desired diameter of the tubular body by means of an expansion mandrel (36) and pressed. By means of the invention, in particular relatively small tubular bodies can be produced economically in relatively large quantities. <IMAGE>
