Patent DE-3151381-A1 (DE)
Title: Sheet forming method
Inventor: PECHA JAROSLAV DIPL-ING
IPC: B21D24/04
Filed: 1981-12-24
Abstract: The invention relates to a method for forming sheets, in particular for the hydromechanical deep drawing of sheet metal, the blank being held by a hydraulic blank holder. It is the object of the invention to provide a possibility for making the blank holder force adjustable in accordance with the drawing conditions and to control it in order in this way to optimise the drawing conditions. The invention achieves this object by the fact that the counterpressure acting on the blank holder is measured continuously by tensometry during the entire drawing cycle, the measured values from the measurement are transmitted to the processing and command device and, from here, the blank holder force is changed to appropriate values.

Title: Device for increasing the frictional resistance between the carriage way and the wheels of a vehicle
Inventor: OLLECH AUGUST
IPC: B60B39/06
Filed: 1982-01-20
Abstract: The invention relates to a device for increasing the frictional resistance between the carriage way and the wheels of a vehicle, in particular motor vehicle. In the travel direction of the vehicle (1), a container (7) which can be filled with granulate (6) and has a floor-side outlet opening (8) is arranged in front of at least each motor-driven wheel (3, 4). The outlet opening (8) can be moved into an open or closed state by means of an opening/closing device (9) by actuating a control device (10) arranged on the driver's seat. Each container (7) is built into the vehicle body (24) in such a way that it can be filled with granulate (6) by means of in each case one closeable filling opening (25) which is located on the vehicle body (24). The granulate (6) can consist of normal, coarse sand or similar means. It is also possible to add a thawing salt or the like to the granulate (6) by which means for example starting processes on carriage ways (5) covered with ice can be made easier. <IMAGE>
Patent DE-3207944-A1 (DE)
Title: Frequency divider which can be set to non-integral division numbers
Inventor: BACKES REINER DIPL ING
Filed: 1982-03-05
Abstract: The non-integral division is carried out by means of an integrally adjustable counter (Z) and a digitally adjustable delay line (V) following the former. The division number (a+0, b) contained in decimal-point notation in a division number register (R) is supplied to a first adder (A1) followed by a buffer memory (S) with respect to its non-integral positions (b) and to a second adder (A2) with respect to its integral positions (a). The output of the buffer memory (S) is connected to the adjusting input (Es) of the delay line (V) and to the second input (E2) of the first adder (A1). Thus, the number corresponding to the non-integral positions (b) is continuously incremented by the non-integral positions (b) at the input of the delay line (V), until a signal occurs at the overflow output (AO) of the first adder (A1) which is supplied to the least-significant position (LB) of the first input (E1) of the second adder (A2). Thus, one unit is added to the integral positions (a) and the counter (Z) continues to count by one position for one counter cycle. In the case of arbitrary non-integral division numbers, the maximum phase jitter amplitude is equal to the shortest delay time which can be set, and is thus much smaller than the clock period (T') of the signal (F) to be divided. <IMAGE>

Patent DE-3215043-A1 (DE)
Title: Ceiling and wall covering with suspension device, consisting of beams capable of being fitted together, connection pieces and fillings
Inventor: RUETH JOSEF
IPC: E04F13/10
Filed: 1982-04-22
Abstract: With the subject of the invention - a method of covering ceilings and walls with beams and fillings of wood or wood-like materials in a fitting-together system by means of a suspension device - disadvantages, such as bulky excess lengths or difficult fastening techniques upon erecting the previous, known and, to a large extent, conventional coverings are to be avoided. These disadvantages are avoided by subdividing, for example, a beam in length, fitting it together in a grid system of, for example, 1/8 metre, screwing it together and fastening it to the building member at certain points with the aid of the suspension device. Fillings of any type can be inserted into the lateral grooves of the beams. The beams can also be fitted together crosswise with the aid of connection pieces. The suspension device is characterised in that the beam or the connection piece is set horizontally and/or vertically in all directions, displaceable about a pin or an eye screw or fixing device connected to a holding clamp, and is stabilised by joining together the ceiling or wall covering. <IMAGE>

Title: Integrated field effect transistor oscillator circuit
Inventor: LINGSTAEDT ERNST
IPC: H03L1/00
Filed: 1982-06-23
Abstract: An integrated field effect transistor oscillator circuit with a feedback oscillating transistor (6) which is connected in series with a regulating transistor (7) of the opposite conductivity type is to be designed with reduced power requirement for more stable operation vis-à-vis environmental effects, such as in particular fluctuations in supply voltage. For this purpose, the oscillator circuit is constructed as a CMOS inverter oscillator (1) in which the transistor structure, which is not equipped with oscillating capacitors (19) and which simultaneously acts as an oscillating and regulating transistor (7) with a separate stabilised source bias voltage (Udv), is operated with variable substrate voltage, this substrate voltage being supplied by an oscillation amplitude controller (2). <IMAGE>
Patent DE-3225003-A1 (DE)
Title: Electromagnetically actuated, proportionally operating directional control valve
Inventor: SCHUMACHER WERNER DIPL ING
IPC: F15B21/044
Filed: 1982-07-03
Abstract: An electromagnetically actuated, proportionally operating directional control valve (10) is proposed in which a pulsed switching magnet (22) controls a servo valve spool (17) and hence a quantity of pressure medium proportional to an analogue input signal (43). The armature of the switching magnet (22) is coupled via a pretensioned actuating spring (32) to the servo valve spool (17), on which a restoring spring (26), which is weaker than the actuating spring, acts in the opposite direction. A restrictor (35) in a channel (34) which connects both end control spaces (23, 25) limits the actuating speed of the servo valve spool (17). As a result of the characteristics (46, 47), which run obliquely with respect to one another, of the actuating spring (32) and of the restoring spring (26), the servo valve spool (17) assumes a stable central position as a function of the duty ratio of the input pulses (44) to the switching magnet (22), in which stable central position it carries out small oscillating movements. The directional control valve (10), which is simple and cheap to construct, operates proportionally and with low hysteresis.

Title: Level control device
Inventor: KAECHELE HEINZ DIPL ING
IPC: B60G17/056
Filed: 1982-07-16
Abstract: The invention proposes a level control device which has a level control valve (7) designed as a slide valve which is equipped with a control slide (16) adjustable by an actuating lever (12) as a function of loading. The control slide (16) is sealed off and guided in a valve housing (13) via two ring seals (17, 18). The spacing of the two ring seals (17, 18) is dimensioned such that this spacing is smaller than the length of a slide, control and sliding surface (16'). In this way, comprehensive control is achieved, guaranteeing a certain play around the neutral position of the level control valve (7). Relatively small lever deflections caused by axle jounce do not have any effect on the slide valve. The level control device can be used preferably in motor vehicles. <IMAGE>

Patent DE-3227697-A1 (DE)
Title: Device for changing an orifice plate inserted in a pipe
Inventor: EICHHOLZ ALFRED
IPC: G01F1/42
Filed: 1982-07-24
Abstract: The invention relates to a device for changing an orifice plate inserted in a pipe. A lower housing portion contains the plate and the plate frame. The latter can be moved, to change the orifice plate, into an upper housing portion which is constructed as a lock and which must be able to be sealed with respect to the lower portion in order to be able to open the lock and remove the plate. The blocking elements hitherto used to obtain this sealing required much technical effort. To reduce this, it is proposed according to the invention that the blocking element be a flap pivotably attached to the underside of the plate frame and extending in an at least approximately radial direction relative to the spindle axis when the plate frame is present in the lock, and movable, when the plate frame is moved into the lower housing portion, into a plane parallel to the plane of the plate frame. The flap which is movable together with the plate frame is advantageously controlled by stops and cams so that it assumes the respectively desired pivoting position.

Inventor: LOLACHI HOUSHANG DR
IPC: B04B11/02
Filed: 1982-11-18
Abstract: A centrifugal apparatus, in particular a flow-through centrifugal apparatus for processing biological fluids in continuous fluid communication, has a flexible tube securely fixed to a rotatably processing chamber and a stationary terminal coaxially above said processing chamber, and being formed in a loop around the outer periphery of said processing chamber so as, in operation, to orbit said loop around said processing chamber at half the rotational speed thereof to avoid twisting or drilling of said tube. To guide said loop of tube in its orbital movement, a rotating frame is provided also rotating at half the speed of the processing chamber. The drive trains for said processing chamber and said rotating frame, respectively, each comprise an individual drive shaft each drivingly connected separate from the other to a drive motor. This avoids any necessity of reversal of rotational direction in the drive trains and allows for a compact and simple construction with a minimum of rotating masses.

Patent DE-3304044-A1 (DE)
Title: Method for controlling passenger lifts and device for carrying out the method
Inventor: HUND HELMUT
IPC: B66B1/24
Filed: 1983-02-07
Abstract: The invention relates to controlling passenger lifts in dependence on the number of passengers waiting for the lift at each storey, and in dependence on the existing loading of lift cabin, in lift systems having several lift cabins. In the space in front of the lift door, sensors sensitive to persons and sensing the number of waiting passengers are installed at each storey. The sensors output electrical signals in accordance with the number of persons sensed, which signals are superimposed on the actual lift control circuit. In the same manner, electrical signals which are proportional to the loading of the individual lift cabins are obtained by suitable sensors. These signals, too, are superimposed on the general lift control. In this manner, the individual request commands to the lift are given weights and the lifts or individual lift cabins move to the particular storeys in the order of these weights, taking into consideration the still available accommodation capacities of each cabin. As a result, the larger number of waiting passengers is given priority over the smaller number so that passenger transportation as a whole can be effected more efficiently and quickly.
