Title: Time-multiplexed data transmission system - handles various subscriber data rates using one fast channel
Inventor: SCHULZ HARRY
IPC: H04J3/16
Filed: 1980-11-08
Abstract: The data transmission system has at least one transmit channel circuit designed to handle a higher data rate than the first subscriber data rate. A channel transmit call clock signal for transferring the transit data (SD2) to the subscriber concerned is passed to the multiplexer central part and relates specifically the higher data rate but is based on the first subscriber data rate. The channel transmit call clock signals generated by the multiplexer central part and coincident with a channel transmit call clock signal (KST2) cause no transfer of data from the transmit channel circuit designed for the first subscriber data rate to the multiplexer central part.

Title: Optical heat sensitive monitor circuit - has heat sensitive element coupled to relay to extend control and monitoring facilities
Inventor: WOLF OTTO DR ING
IPC: H02H7/08
Filed: 1980-12-12
Abstract: The optical monitor is coupled to a heat monitoring circuit on electrical equipment. The optical unit indicates that an excessively high operating temperature has been reached and causes a control circuit to reduce the revolutions of a motor for a degree of cooling to take place. The monitor is associated with temperature sensitive operating circuitry in the proximity of a heat producing equipment, e.g. an electric motor, and is used to reduce heat output to protect the sensitive circuitry. The heat sensitive element (4) controls a switch (19) which is in the control circuit (11) of a thyristor or triac (9) in the regulatory electronic control circuit (8) to a motor (1). Triggering the thyristor or triac (9) either switches a potentiometer (14) into circuit for control purposes or switches the motor from a maximum voltage to a reduced voltage supply. The heat sensitive element (4) may be a bimetal unit and the coupled switch (19) a relay or antiparallel thyristor/triac circuit.
Patent DE-3049307-A1 (DE)
Title: Supervisory circuit for generator cyclic loads - measuring rate of load change and initiating trip if rate and frequency are above set limits
Inventor: MEUSEL WOLFGANG ING GRAD
IPC: H02H7/06
Filed: 1980-12-29
Abstract: The application of the proposed circuit is principally to generators which can be subjected to cyclic loads of a magnitude lower than that detectable by normal protection circuits. Generators connected to an HVDC transmission system can be subjected to such loads. A wattmetric transducer (2) connected to the generator output passes signals to two asymmetrical level detectors (3,4), one being the opposite of the other. The level detectors drive integrators (5,6) with feedback to the detector input. These two channels follow load increase (5,AB) and load decrease (6,AUF) respectively. If the proportion of change to actual power (7,8) exceeds a limiting value (9,10) a bistable circuit (11) is tripped, and its output applied to a counter (Z). This initiates a trip (AS) after a set number of impulses in a time given by a monostable (13). With the circuit dangerous power oscillations can be detected and the machine unloaded when the magnitude of the change is within the normal overload protection limits.

Title: Circuit arrangement for testing functional units of a data-processing system controlled by binary signals
Inventor: MARINGER ALBERT ING GRAD
IPC: G06F11/00
Filed: 1981-02-05
Abstract: A first current monitoring arrangement (STU1, STU3, STU5) is connected between a first functional element (FEL1, FEL3, FEL5) and a second functional element (FEL2, FEL4, FEL6) controlled by the output current of the first. A series circuit comprising a second current monitoring circuit (STU2, STU4, STU6) and a resistor is impressed with the voltage which is fed to the first current monitoring arrangement. The output signals of the two current monitoring arrangements (STU1, STU2) and the control signals for the first functional element (FEL1, FEL3, FEL5) are fed to a logic circuit (LG) which derives signals therefrom which identify any faults in the functional elements. The invention is used for the automatic testing of functional units (FEH1, FEH2) contained in data-processing systems. <IMAGE>

Title: Hydraulic motor for pneumatic-hydraulic energy converter
Inventor: WILLIG KURT
IPC: F03C2/30
Filed: 1981-02-27
Abstract: This hydraulic motor is primarily designed for installation in the pneumatic-hydraulic energy converter Ref. P 2940191.0. This energy converter functions with a fluid circuit and would be usable as a drive in virtually all spheres, power generation, vehicles etc. The fact that the oil circulation can be greatly reduced by fitting this hydraulic motor into the energy converter is to be seen as its most important advantage. According to the invention this is achieved by shifting the swept volume from the circumference to the inside of the rotor. The spaces between the blades pressed inwards can be kept much smaller. A further tendency is the special embodiment with flywheel (drawing, fig. 4 + 5). The blades no longer have to be forced with the antifriction bearing into the swept volume, that is on an inclined plane, which means a great loss of torque, but rotate on the anti-friction bearing or a sliding ring without any significant resistance until they are caught by the flywheel and forced into the swept volume. <IMAGE>

Title: Angle profile for terminating floor or wall coverings consisting of ceramic material or the like
Inventor: SCHLUETER WERNER
IPC: E04F19/06
Filed: 1981-06-02
Abstract: The aim of the invention is to propose an angle profile for terminating floor or wall coverings consisting of ceramic material or the like which can be produced more cost-effectively than known profiles of this type and by means of which high loadings occurring in the border region of the ceramic plates can be largely avoided. Such an angle profile has a very thin fastening leg (1) having a thickness of less than 1.5 mm and in which through-passages (11) are provided. The shorter, terminating leg (2) is designed with approximately the same thickness and its outer flank (21) encloses an angle of less than 90 DEG , preferably 80-89 DEG , with the fastening leg (1). The inner transition between the fastening leg (1) and the terminating leg (2) is designed with a concave moulding. On the free end of the terminating leg (2) there is integrally formed an inwardly directed widening (3) which is essentially rectangular in cross-section and the thickness of which is at least double the thickness of the rest of the terminating leg. <IMAGE>

Title: Autofocusing device for lenses
Inventor: FELLE KARL DIPL PHYS
IPC: G03F7/207
Filed: 1981-06-03
Abstract: The method according to the invention is used to determine the displacement of the focal plane (9) which is caused by changes in air pressure or by changes in temperature in the case of lenses for high-resolution aerial photographic systems. The displacement can then be corrected by an adjusting movement of a lens element (2a). For this purpose, between the exposure operations a grid (7) arranged in the lens is exposed and projected in autocollimation via a partially mirrored surface (1) on the front side of the lens onto a detector (5) arranged in the film plane. This detector consists of a detector array which is inclined relative to the film plane (4) and comprises approx. 2000 elements. The output signal of the detector is modulated by the periodicity of the grid (7). The maximum of the modulation amplitude determines the point of intersection of the detector array (5) with the focal plane (9). Its offset (deviation) from the centre position is used to perform microprocessor-controlled fine adjustment of the adjustable lens element (2a). <IMAGE>
