Patent DE-3728809-A1 (DE)
Title: Circuit arrangement for limiting a switching-on current (connection current)
Inventor: SCHUHBAUER ERNST DIPL ING
IPC: H02H9/00
Filed: 1987-08-28
Abstract: In the case of power supply units which produce a DC voltage (U2) from an AC voltage (U1) and in the case of which the DC voltage (U2) is picked off on a capacitor (C) which is charged via a rectifier (G), it is intended to limit the switching-on current when a switch is operated. In order to limit the switching-on current, the capacitor (C) is charged via a resistor (W1) as soon as the unit's mains plug is inserted. When the unit is switched on by means of a switch, the DC voltage (U2) is supplied to the load via a first switching element (S1) of the switch, and the resistor (W1) is at the same time bridged (shorted out) by a second switching element (S2) of the switch. Power supply units in which no transformers are provided. <IMAGE>

Title: Shearer loader equipped with pivotable supporting arms for underground operation
Inventor: WEBER KARL-HEINZ DIPL ING
IPC: E21C31/10
Filed: 1987-09-01
Abstract: Shearer loaders whose cutting drums are equipped with drive motors located in the interior of the drum body require a specially protected arrangement of the sections, leading to the cutting drums, of the power feed line in the supporting-arm area. This arrangement is made more difficult especially in shearer loaders whose cutting drums are arranged on supporting arms variable in length. In both supporting arms (2) of the shearer loader (1), the power feed line (11) running to the drive motors (7) is run through the inner space (15) of the supporting arm (2) and is secured in the entry and exit area of the inner space (15) of the supporting arm. Here, this line section (11a) runs in a loop shape inside the supporting arm (2) in a manner which does not restrict the mobility of the displaceable supporting-arm section (2b). <IMAGE>

Title: Apparatus for stretching a moving web of material
Inventor: STEFFL MANFRED
IPC: D06C3/02
Filed: 1987-12-08
Abstract: With known apparatuses for the simultaneous biaxial stretching of a film web, the longitudinal stretch ratio cannot be readily altered. To be able to produce different plastics materials with different stretch ratios or else the same materials with different stretch ratios, in the run-in region ahead of the stretching zone (B) there is provided a setting device for setting the longitudinal stretch ratio. By this means, with a given length of the scissor chain links (9), the minimum distance between two neighbouring carriages (15) can be set differently, thereby fixing the longitudinal stretch ratio. The apparatus is suitable in particular for the simultaneous biaxial stretching of plastics film webs. <IMAGE>

Patent DE-3825768-A1 (DE)
Title: Compress-gas-operated shooting weapon
Inventor: LUDWIG WALTER
IPC: F41B11/55
Filed: 1988-07-29
Abstract: A multi-shot sport pistol which is operated using CO2 gas or compressed air has a projectile magazine which can be displaced transversely with respect to the firing direction and is acted on by a magazine spring in the feed direction. The positive control of the feed movement of the projectile magazine is effected by a stepping switching mechanism which is driven by the recoil movement of a sear. When the shot is fired, the cocked sear is released by operating the trigger and strikes a valve which is in consequence opened. When the sear is pushed back by hand or automatically by the gas pressure into the cocked position, the locking of the projectile magazine in the firing readiness position is released via the stepping switching mechanism, so that the projectile magazine is automatically moved onwards by the magazine spring by one division of the projectile retaining chambers.

Title: Ice-drilling means with an oxygen-supply device for avoiding fish losses during the frost period, in standing and flowing bodies of water
Inventor: SCHUNKE ANGELIKA
IPC: A01K63/04
Filed: 1988-09-20
Abstract: Device and process serve to prevent fish losses which occur again and again as a result of closed coverings of ice during the frost period.   By virtue of the fact that the ice is drilled and no longer has to be hacked up, stress situations among the fish, which lead to increased oxygen depletion, do not arise. The exchangeability of the ice-drilling means for a water-jet pump makes it possible for the water beneath the covering of ice to be supplied with oxygen via compressed air with an oxygen admixture. Apparatus and process can be used everywhere, irrespective of the thickness of the covering of ice and of the magnitude and depth of standing or flowing bodies of water.

Patent DE-3839637-A1 (DE)
Inventor: HOFMANN KARL DIPL ING
IPC: F02M61/20
Filed: 1988-11-24
Abstract: A fuel injection nozzle for internal combustion engines has a nozzle body (10) fastened to a nozzle holder (13) by an intermediate disk (11), a valve needle (14) which slides in the nozzle body (10), an intermediate bushing (24) which slides axially in the intermediate disk (11) and a closing spring arrangement consisting of two helical pressure springs arranged one behind the other in a spring chamber (19) in the nozzle body (10). The total stroke of the valve needle (14) executed against the closing spring arrangement is divided into a clearance stroke and a residual stroke by limit stops (25, 28) and counter limit stops (26, 27) on the intermediate bushing (24), intermediate disk (11) and valve needle (14). To obtain a short closing spring arrangement and hence an injection nozzle of short overall length, the second closing spring (22) acts on the intermediate bushing (24) via a spring plate (31) and a sliding bushing (30) surrounding the first closing spring (21), while the first closing spring (21) abuts on the spring plate (31) and, via a second spring plate (34) and a pressure pin (23), on the valve needle (14). Each closing spring (21, 22) therefore acts only during a partial stroke and can be simply dimensioned.
Patent DE-3902723-A1 (DE)
Title: Screen mounting on profiled-frame luminaires
IPC: F21V17/10
Filed: 1989-01-31
Abstract: In known designs, the transparent cover screen is placed in four encompassing grooves. To change the lamp, frame parts have to be removed completely from the luminaire. In the design according to the invention, all frame parts remain connected to the luminaire. The displacement of a frame part results in a free space through which the cover screen can be taken out. As a result of this design, a screen can be taken out of circumferentially closed grooves in a very assembly-friendly manner, which is necessary e.g. for changing the lamps.
Patent DE-3908266-A1 (DE)
Inventor: FUHRMANN ERNST DIPL ING
IPC: F28D1/053
Filed: 1989-03-14
Abstract: The invention relates to a heat exchanger comprising a heat exchanger grid having a multiplicity of oval tubes (3), and a baseplate attached to said grid by widening the tubes (3). The ratio of the diameters of the tubes (3) is 2.5 : 1 to 8 : 1 inside the heat exchanger grid, and 1.2 : 1 to 3 : 1 inside the perforations of the baseplate. A process for fixing such heat exchanger grids to a baseplate is also described. This process is characterised in that before being widened the tube ends are deformed from outside by applying pressure with the aid of a special pressure tool (15, 15a,b), with the result that their cross-sections are reduced parallel to the maximum diameter but increased, by contrast, parallel to the minimum diameter. <IMAGE>
