Title: Transformer having secondary voltage addition in accordance with the binary and value (significance) system
Inventor: ERZMONEIT HORST
IPC: H01F29/02
Filed: 1981-07-21
Abstract: Small transformers exist - as is already known - having various taps on the primary and secondary. As is already known and in accordance with the technical prior art, transformers exist having any desired number of taps for voltages on the secondary. The novelty of the transformer described is that the windings for the voltage on the secondary are arranged in terms of magnitude in accordance with the binary system. Using this system it is possible to pick off 31 different voltages, stepped down to the smallest base voltage, from only six taps by switching over; for example: Binary system          Winding          Tap 0 V       1  base voltage =      1 V              1 V       2 2 V              3 V       4                      4 V              7 V       8                      8 V             15 V      16           16 V             31 V   The arrangement of the sequence of the secondary windings can be varied in accordance with the requirements, for example 4-1-16-2-8. As a result of arranging the secondary windings in terms of magnitude in accordance with the binary system, transformers can be used more flexibly and can be produced more economically, for general production.

Patent DE-3214121-A1 (DE)
Title: Counter dispensing-pump
Inventor: ALBERT THEO
IPC: B67D1/06
Filed: 1982-04-16
Abstract: The invention relates to a counter dispensing-pump and is suitable in particular for a bar counter. The previous space utilisation of the overall arrangement of a counter and of a counter dispensing-pump brought considerable disadvantages both for the upper work surface on the counter and for the internal space utilisation of the counter. These disadvantages are overcome in that on the one hand the dispensing pump is no longer arranged on the previously usual fastening region but is displaced to the outermost front region of the work surface of the counter. Inside the counter, the dispensing pipes are guided on the front delimiting wall of the counter so that the counter interior remains essentially without an inconvenient transverse running of the dispensing pipe. In the upper region, the dispensing pump is shaped with a short pump bend so that the entire dispensing pump projects only slightly beyond any bar board and subsequently has a horizontally aligned pump end towards the dispensing point.
Patent DE-3220164-A1 (DE)
Title: Variable multi-purpose profile system
Inventor: BARTEL WIELAND
IPC: E04F13/08
Filed: 1982-05-28
Abstract: By choosing a simple profile shape, a versatile system can be built up, for example as a wall covering, flat-roof edge profile, curtain rail or handrail. The system consists of an edge profile and a connection profile. The fastening part is integrated into the edge profile in such a way that it can be packed in a space-saving manner. A special rotation-locking mechanism permits efficient mounting. The fastening part can be equipped with a force-dependent detachable connection. The connection profiles can be suspended from one another in an endless sequence starting from the edge profile, it being possible for the parts to be fixed folded at 90 degrees. In this position, a forced rear ventilation is maintained. The entire system is movable per se so as to compensate for thermal movements and thus fulfils an important requirement of DIN 18339. The edge profile itself is a single part, whereas comparable commercially available profiles have to be put together from a plurality of individual parts during mounting. The specially designed profile loop in the edge profile produces, together with the coupled connection belonging to the system, a labyrinth which is secure against automatic uncoupling while retaining free mobility in accordance with DIN 18339.

Title: Hydraulic control device with at least two way-valves for controlling two pressure medium flows
Inventor: OLBRICH GOTTFRIED DIPL ING
IPC: F15B11/17
Filed: 1982-06-11
Abstract: A hydraulic control device (10) for controlling two pressure medium flows to a common, single-acting servomotor (26) is proposed, the control slide valve (28) being of short construction. A motor chamber (57) lies between a first circulation chamber (59), assigned to a first neutral circulation duct (16), and a feed chamber (56), which both have a connection to a first pump (15), whilst a second circulation chamber (55) and a return chamber (54) lie in a second neutral circulation chamber (22), into which the second pump (21) delivers. The pressure sides of both pumps (15, 21) are connected to one another by way of a cross connection (23) with non-return valve (24). A second piston section (65) of the control slide valve (28), in the lifting position immersing into the feed chamber (56), enables the flows of the two pumps (15, 21) and their control to the motor connection (27), which when lowering can be relieved by way of a longitudinal duct (68) lying in the control slide valve (28), to be combined. The first directional control valve (11) processes two flows with just five controlled chambers (54, 55, 56, 57, 59) and is of compact construction, it being being possible to use existing housings (51). <IMAGE>

Title: Drive arrangement for a motor vehicle
Inventor: HEIDEMEYER PAULUS DIPL ING
IPC: H02K7/00
Filed: 1982-11-25
Abstract: The drive arrangement for a motor vehicle has an internal combustion engine, essentially without flywheel, a flywheel held freely rotatable in a bearing and connectable, in each case by way of a controllable clutch, to the combustion engine and an output leading by way of a transmission to the drive wheels, which flywheel comprises the pressure plates of the controllable clutches, and an electrical machine for driving the motor vehicle and/or starting of the internal combustion engine, which machine has a stator connectable to fixed housing parts of the internal combustion engine and a rotor connected to the rotating flywheel. In order to achieve a compact and as far as possible space saving arrangement of the rotor of the electrical machine, the rotor (33, 34, 35) of the electrical machine (3) is to form an integral component of an axially fixed pressure plate part (21) of one of the controllable clutches, preferably of the clutch (6) on the internal combustion engine side. At the same time it is advisable to arrange the electrical machine essentially in the radial plane of the bearing (16) assigned to the flywheel (4). <IMAGE>
Patent DE-3244920-A1 (DE)
Inventor: GOETTLING HELMUT
IPC: F15B15/02
Filed: 1982-12-04
Abstract: A force transmitting fluid actuator for use with a control device wherein an actuator member, movable within an actuator housing, actuates the control device due to the urging force of a plurality of pistons which can be selectively pressurized in unitary increments. The plurality of pistons are disposed within pressure chambers formed in the actuator housing in a symmetrical ring-shaped arrangement concentric to a single pressure chamber disposed on the vertical axis of the housing. A number of passageways interconnect the plurality of pressure chambers to form groupings of pressure chambers which act simultaneously in response to operation of a solenoid valve associated with each passageway. In addition to the symmetrical arrangement of the pressure chambers, the valve and passageway arrangement provide for a symmetric pressurization of the pressure chambers thereby resulting in a balanced force being exerted on the actuator. The amount of force each piston can exert on the actuator is limited by a piston stop designed to contact a portion of the housing while the actual piston force is transmitted by a spring disposed between each piston and the actuator. In this manner, fluctuations in the pressurizing force are not transmitted from the piston to the actuator.
