Patent DE-3227526-A1 (DE)
Title: Hydrostatic drive
Inventor: HEISER JOACHIM DIPL ING
IPC: F16H61/42
Filed: 1982-07-23
Abstract: The hydrostatic drive according to Figure 1, comprising a variable displacement pump (10) and a hydraulic motor, has a control device with an electromagnetically actuated proportional or servo valve (45) which controls an adjusting device (14) for the pump. Fluid pressures and prestressed springs (18, 19) act on the double-acting piston (13) of the pump. A speed sensor (70) is formed on the hydraulic motor (28), which, in particular, likewise has a variable displacement, and feeds the actual speed value of the hydraulic motor to an amplifier (67), into which the setpoint speed value of the hydraulic motor is also input. In the amplifier (67), the values are compared and, if they do not coincide, appropriate control currents from (I1 and I2) are fed to the control valve (45). This produces control pressures (p1, p2) for the pump and the hydraulic motor. If the hydraulic motor is of variable displacement design, it is only varied if the pump (10) is at the maximum setting. In this way, extremely precise and simple control of the speed of a hydraulic motor in a hydrostatic drive is obtained. <IMAGE>

Title: Vacuum generation for a combustion engine
Inventor: WIELAND ALFRED DIPL ING
IPC: B60T17/02
Filed: 1982-10-21
Abstract: Most passenger motor vehicles are nowadays equipped with vacuum-operated brake boosters. In the case of diesel engines the vacuum required for the brake boosters is generated by special vacuum pumps which are relatively expensive and unnecessarily consume energy for their constant drive. These vacuum pumps are replaced cost-effectively by the invention in that the vacuum required for the brake boosters is generated in the air intake duct of the diesel engine, to which duct the brake booster is connected. For this purpose a throttle valve is arranged in the air intake duct, which valve is closed by means of a vacuum switch when the required vacuum for the brake booster is not sufficient. It is opened when an adequate vacuum is present.

Patent DE-3322654-A1 (DE)
Title: Method for seizing an exchange line in a microprocessor-controlled branch exchange which is not isolated towards the exchange line
Inventor: FORDAN GUENTER
IPC: H04Q3/62
Filed: 1983-06-23
Abstract: In this branch exchange, a keyboard with directory number memory is used as dialling element at the subscriber station for dialling to the exchange system. When dialling outside subscribers with the keyboard, the dialling is immediately continued with the subscriber number after the exchange code has been dialled. If the full loop current is not yet available at this time, the branch exchange detects loop interruption and interrupts the further dialling. This is to be prevented. According to the invention, a holding resistor is connected to the subscriber line in the branch exchange via a holding relay contact directly after exchange line seizure and the dialling of the subscriber number is only continued when the microprocessor of the branch exchange is activated via a contact of the loop relay which is now operated with full loop current. This prevents unwanted interruption of the dialling.

Filed: 1984-03-15
Abstract: The insulating edge tape is provided with a median longitudinal segment (5) of which one face has an ondulated profiling (8). Said median longitudinal segment (5) is edged on one end by a first longitudinal segment (6) flat on both sides and on the other end by a second longitudinal segment (7) flat on both sides. The thickness (9) of the first longitudinal segment (6) flat on both sides is equal to half of the spacing separating the lower face (1) of the insulating edge tape from the top of the receptive ondulation (13). Said spacing (14) is equal to the thickness (11) of the second longitudinal segment (7) flat on both sides. A longitudinal segment (26) is provided between the first longitudinal segment (6) flat on both sides and the median longitudinal segment (5) to facilitate a bending of the insulating edge tape. Since the ondulated profiling (8) is horizontal when the insulating edge tape is mounted, it is impossible to foreign bodies to fall in the ondulating cavities and to affect the flexibility of the insulating edge tape. Furthermore, the fabrication of said insulating edge tape is cost-saving.

Title: Roasting device
Inventor: BIRBAS GEORGIOS
IPC: A47J37/04
Filed: 1984-03-20
Abstract: A roasting device for preparing "gyros" has a roasting spit which can be inserted in a receiving device provided with a rotary drive device and can rotate about a vertical axis and a heating device which extends over part of the range of rotation of the roasting spit, is arranged in the receiving device and is shielded on its side facing away from the roasting spit. In order to improve a roasting device of this type to the effect that the roasting operation leads to moist roasted meat with favourable characteristics in terms of energy consumption, provision is made for the receiving device to have a closure device of transparent construction in that part of the range of rotation of the roasting spit which has no heating device. The roasting device can thus be closed during the roasting operation so that the roasting operation takes place in a (substantially) closed space.
