Patent DE-3301076-A1 (DE)
Title: Diaphragm shutter designed as a programmed shutter
Inventor: BRIXEL ALFRED
IPC: G03B9/24
Filed: 1983-01-14
Abstract: The invention relates to a diaphragm shutter designed as a programmed shutter. Use of the diaphragm shutter as a programmed shutter is rendered possible by subjecting the opening ring of the shutter to the action of a retarding mechanism as it operates. For space-saving reasons, this retarding mechanism is specially designed as a pivotable fork whose fork tines are in each case provided on the insides with a row of teeth which are offset with respect to one another by half an increment. As the opening ring operates, an anchor connected to the opening ring slides through between the teeth and in so doing continually pivots the fork to and fro. The operation of the opening ring is slowed down in this way. It is also possible for the purpose of disconnecting the retarding mechanism for the fork tines to be spread so far apart that the anchor passes freely between the teeth.

Title: Electric washing machine
Inventor: SCHEER ERICH DIPL ING
IPC: D06F34/18
Filed: 1983-03-15
Abstract: The invention relates to an electric washing machine having a device for the automatic control of its fresh-water inflow. Provision is made, in this, for previously determining the float height for the washing liquor in dependence on the weight load on the washing drum or tub by the dry laundry introduced. This weight parameter can be supplemented by the manual input of further parameters, such as the type of fabric and the degree of soiling. The various parameters are converted into, among another other things, a corresponding float height by means of a microcomputer. The float height of the washing liquor itself is, in turn, also determined by the weight of the tub. There is provided between the housing and the tub a weight-sensor device which determines electrically the respective weight load both with the dry laundry introduced and with fresh water flowing in.

Title: Method and device for the operation of an internal combustion engine
Inventor: BAUMGARTNER HANS DIPL ING
IPC: F02D9/02
Filed: 1983-04-15
Abstract: In a method for the operation of an aspirated internal combustion engine with a gas engine driven by the combustion air, the efficiency of the gas engine, particularly in the lower load ranges of the internal combustion engine, is improved in that the combustion air is increasingly heated upstream of the gas engine as the load demand on the internal combustion engine decreases. A gas engine driven by the combustion air drawn in by the internal combustion engine has a control element, operated together with a charging governor of the internal combustion engine, for mixing combustion air drawn directly from the atmosphere with warmed combustion air drawn through a heat exchanger heated by the exhaust gas of the internal combustion engine.
Patent DE-3316842-A1 (DE)
Title: Method for transferring heat, and device for carrying out the method
Inventor: FRIEDRICH HANS GUENTER DIPL IN
IPC: F25B1/04
Filed: 1983-05-07
Abstract: The transfer of heat between two heat exchangers (2, 3) is served by a circulating refrigerant which can change its aggregate state. A conveying device (4) in the closed-circuit pipeline (1) for the refrigerant consists of a rotating drum (6) having dampers (7) which bear against an external cylinder (8). Owing to a slightly eccentric position, the annular gap (11) between the drum (6) and the cylinder (8) firstly increases slightly towards the outflow end (10), and subsequently decreases. This leads firstly to a slight expansion of the incoming mixture of liquid and vapourous refrigerant and to evaporation of the liquid part owing to heat absorption from the surroundings and from the kinetic energy released by the conveying device, and subsequently to a slight compression. <IMAGE>

IPC: C10B1/10
Filed: 1983-06-03
Abstract: The subject of the invention is a rotary drum for the treatment of bulk material with at least one revolving portion of which projects into a stationary housing, a support frame or a similar component, and which is sealed with respect to the latter by at least one sealing arrangement. To ensure a secure sealing even in the event of positional changes of a sealing element which are to be attributed to changes in operating conditions, according to the invention the sealing arrangement is embodied as a slide ring seal (41,42) with radial sealing faces (43), one slide ring (41) of which is connected to the revolving rotary drum part (45) and the other (42) is connected to the stationary housing part (53), one of the slide rings (42) being articulately coupled via two lever rods (55) having a universal joint (47, 56, 57) to two pressing force generators (60) and connected via a support ring (46) to a bellows (50). <IMAGE>
Patent DE-3325885-A1 (DE)
Title: Method for serial polling of radio channels
Inventor: HANSEN JENS DIPL ING
IPC: H04W74/00
Filed: 1983-07-19
Abstract: A method is proposed for serial polling of n staggered-frequency radio channels in a cyclical sequence. With the method, an occupied radio channel is intended to be identified within a permissible identification time which is at least equal to the time required for the identification of n occupied radio channels. An electronic polling device is used for polling and identification. In order to reduce power consumption for the polling device, it is proposed according to the invention that, if a polling cycle (Z3) ends before half of the permissible identification time (tF zul) has elapsed, a waiting time (tW) begins. During this waiting time, modules associated with the polling device which have a high power consumption are de-activated. When the waiting time has elapsed or at the end of the permissible identification time, the next polling cycle (Z4) begins. If, however, a polling cycle (Z6) requires an identification time which is longer than half of the permissible identification time, the subsequent polling cycle (Z4) follows on immediately after the preceding polling cycle. <IMAGE>
Patent DE-3326591-A1 (DE)
Title: Rotary tool
Inventor: ROLF PETER
IPC: B25B23/145
Filed: 1983-07-23
Abstract: A rotary tool for tightening or loosening screws has a gear part (16) whose input shaft (29) is driven by a hydraulic motor (15). The input shaft can be connected to the output shaft (30) via a first clutch (31, 33). A hydraulic piston (53), which is actuated as a function of the load moment, displaces the input shaft (29) via a plate (38), as a result of which the first clutch (30, 31) is disengaged and a second clutch (38, 39) is engaged. On the output side, the second clutch (38, 39) drives two planetary gear stages (42, 42') connected in series, of which the last drives the output shaft (30). If the load moment exceeds a limit value, the power no longer flows from the input shaft (29) via the first clutch (31, 33) to the output shaft (30) but from the input shaft (29) to the second clutch (38, 39) and via the two gear stages (42 and 42') to the output shaft (30), which is thereby driven at a lower speed and with a higher torque. <IMAGE>

Title: Continuously adjustable heat-pump heating installation with continuously working operating systems
Inventor: VINZ PETER DR ING
IPC: F24D11/02
Filed: 1983-11-30
Abstract: An economical heat-pump heating installation is presented, which can be operated continuously in the partial-load range between 0 and 100%. It consists of a continuously working heat pump driven by an internal combustion engine or an electric motor, a small heat reservoir and one or two peak-load boilers which work in modulating fashion. The continuous heat-pump operation is achieved by an improved refrigerant compressor which contains, in addition to its continuously working volume-controlling device, a device for adapting the compression ratio to the saturation pressures, reduced in the partial-load range, in the refrigerant condenser. In addition, the heat pump works with an improved thermodynamic cyclic process, since it utilises extended condensate undercooling to heat the domestic water.

Title: Electrical vacuum switch
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/66
Filed: 1983-12-30
Abstract: As an essential precondition for a considerable spatial reduction in size of metal-encapsulated, gas-insulated, medium-voltage switching installations, the insulating material components of the vacuum switches which are to be inserted therein are dimensioned in accordance with the electrical breakdown strength of the surrounding insulating gas. In the case of vacuum switches having metallic switch housings (1) and (15) and insulating bushings (2, 3) and (2a, 3a), or (16) and (16a) respectively, in different insulating media, the dimensions of the switch housings remain unchanged. In contrast, the insulating bushings have different lengths: for the same operating voltages they are dependent on the electrical breakdown strength of the surrounding insulating media, for example atmospheric air or SF6. Particularly in the case of vacuum switches having one insulating bushing (16) or (16a) respectively per switch housing (15), the insulating bushing (16b) expands to a body (16c) which encloses the switch housing like a cap. <IMAGE>

Title: Circuit arrangement for controlling the brake pressure in antilock-protected vehicle brake systems
IPC: B60T8/173
Filed: 1984-01-27
Abstract: A circuit arrangement for controlling the brake pressure in antilock-protected vehicle brake systems is described. In known systems of this type the brake pressure, following a fall in pressure, is first increased by a large pressure pulse and thereafter by smaller pressure pulses. By contrast the pressure build-up in the invention occurs firstly by means of a small and thereafter by means of a large and finally by means of further small pressure pulses. This pressure control avoids axle vibrations and unnecessary pressure reduction phases. <IMAGE>
