Title: Clamping ring for roller bearings - has supporting shoulder and sealing lip for inside race
Inventor: BREDEHORN FRIEDRICH ING GRAD
IPC: F16C13/00
Filed: 1978-06-06
Abstract: The holding spring ring is usesd for roller bearings and is fitted into a groove in the bore accommodating the bearing outside race and the ring rests axially against the outside race. These rings are readily fitted and stocked and a relatively narrow range of rings is used. The holding ring has a circumferential shoulder (17) on its outside circumference which is supported axially in a side wall of the groove (14). It has an integrally moulded elastic sealing lip (26) which slides on the end face of the bearing inside the race (20) so that this clamping ring acts also as a sealing ring. The outside region is elastically deformed on axial insertion of the ring into the bearing bore (10).
Patent DE-2825052-A1 (DE)
Inventor: SPIEGEL HUBERT
IPC: H02B13/065
Filed: 1978-06-07
Abstract: The pressure-relief device (2), which is shown in longitudinal section, consists of a cylindrical body (3) (which has a cylindrical hole passing through it), of a piston (5) (which is inserted into said cylindrical body (3) such that it is sealed by means of a seal (4), and of a connecting element (6) which mechanically connects the piston (5) to this cylindrical body (3). The connecting element (6) consists of a metal plate which is provided with a weak point (7) which is formed by circular cut-outs. If the predetermined pressure on the side of the piston (5) carrying the connecting element (6) is exceeded, the weak point (7) of the connecting element (6) tears. The piston (5) is thereafter ejected from the hole in the cylindrical body (3). Pressure relief thus occurs through the hole which has become exposed in the cylindrical body (3). The scatter in the response pressure is low despite a cost-effective type of construction. <IMAGE>

Title: Load cell measuring circuit in electronic scales - uses strain gauge bridge and amplifier and has temp. and nonlinearity compensation
Inventor: LOTZ GERHARD DIPL PHYS
IPC: G01D3/02
Filed: 1978-09-12
Abstract: Strain gauges (DM1, DM2, DM3, DM4) form a bridge and are mounted onto a tube which forms a load all. A voltage supply, the strain gauges and an amplifier (V2, T2, T3) are thermally connected as one module. Temperature dependant resistors (RT1, RT2, RT3) in the supply line and one of the bridge branches supply temp. and zero point temp. error compensation. The amplifier's output (T3) is fed back negatively to a resistor (RG1) in the second bridge branch. This ensures that the amplifier delivers a current proportional to the bridge voltages. Since the strain gauge voltage is not exactly proportional to the load a compensating linearization network (T4, T5) is connected in series with the amplifier.

Patent DE-2849019-A1 (DE)
Title: Centrifugal compacting of fine granules - in rubber lined bowls replacing wheels on motor vehicle differential axle
Inventor: BALSTER HUGO DR
IPC: B04B9/08
Filed: 1978-11-11
Abstract: Fine granules with or without a binder are converted to large lumps of regular size by centrifugal action. Two centrifugal bowls replace the wheels on a conventional differential axle of motor vehicles which is driven by a reversible motor. Each bowl is lined with rubber which has honeycomb cavities to suit the desired shape of the final prod. This a simple and low-cost drive which saves power because the kinetic energy of a spinning bowl can be used to accelerate a stationary bowl after it has been charged. A deflection of the lining towards the centre will remove the final pieces from the cavities of the lining.

Title: Electric vehicle motor regulation unit - monitors amplitude of armature current determined by divider gate set by vehicle switch
Inventor: NIEHAGE HELMUT ING GRAD
IPC: H02P7/298
Filed: 1978-12-15
Abstract: The regulation unit is for a current-controlled vehicle motor supplied by a control current, w.r.t. the motor stray field, the regulated-amplitude of the armature current is fixed via a divider-gate, whose divider stage is set via the vehicle switch. The armature of the vehicle motor is fed from an armature-current regulator via a smoothing choke, while the field winding is connected to a current regulator. Control of the armature-current-regulator is determined by the control angle of the valve and a control voltage, for which the control-amplitude is set via a potential-dividing transformer from the armature-terminal voltage. The lead-amplitude for the armature voltage is provided via a pre-set transmitter. The control deviation in the amplitudes guides the voltage regulator, whose output amplitude corresps. to the current regulation and sets the lead amplitude for the armature current.

Title: Headlight adjustment system for vehicle - sets angle of tilt of headlights according to load carried by vehicle
Inventor: ANDREI-ALEXANDRU MARCEL DIPL I
IPC: B60Q1/115
Filed: 1979-08-17
Abstract: The system has a measuring system measuring the position of the bodywork of the vehicle w.r.t. a fixed plane before the vehicle is loaded. This position is retained in a memory. The measuring system then measures the position of the bodywork when the vehicle is loaded and compares it with the stored position to produce a signal that adjusts the angle of tilt of the headlights. The unloaded measurement is initiated when a door of the vehicle is opened and the loaded measurement is initiated when the last door is closed and the ignition switch operated. The measuring system uses one (or two) pendula (14,15) to determine relative position. The pendulum is mounted on one headlight and its axis of pivot is the same as that of the headlight.

Title: Matrix display with magnetised cylinder elements - which rotate when current is fed to support wires
Inventor: HUBER ERIC DIPL PHYS
IPC: G09F13/04
Filed: 1979-10-19
Abstract: Each element of a matrix display is a short cylinder free to rotate about its axis. A number of cylinders with their axes in line form a row, and a number of rows form the matrix plane. Each row of cylinders is supported by four straight wires (3,4,5,6) parallel to their axis, at the corners of a square enclosing the cylinders. A pair of wires, (3,5 or 6,4) is common to two adjacent rows. The end faces of the cylinders (14,15) are separated by straight wires (1,2) run between them and align the cylinders into columns. Each cylinder is permanently magnetised across a diameter (N,s) Any cylinder can be addressed by applying suitable currents to two of its row wires (3,4,5,6) and its two column wires (1,2). The resultant magnetic field rotates the cylinder into one of four positions, without affecting other cylinders. This brings one of three different coloured areas (21,22,23), or a blank, into the matrix viewing plane to form an element of the display.
