Patent DE-2345628-A1 (DE)
Title: Wheel rim with deepened groove on one side - having an insert to form support for tyre wall
Inventor: TIEMANN REINHARD DIPL-ING
IPC: B60B21/12
Filed: 1973-09-10
Abstract: The wheel rim has a deeper groove on one side to take the tyre wall when the tyre is changed. During normal use the groove is filled by a special ring which forms a support surface for the tyre wall with a similar profile as the wheel rim on the other side. The groove extends over the width of the tyre wall, or further, with the ring covering the whole groove. The outer edge of the ring is contoured to fit in with the edge of the tyre rim, where it curls over to form a smooth lip. To remove the tyre it is deflated, pressed inwards on one side and the ring removed.

Title: Infinitely adjustable back rest of bed frames - comprises pressure-adjustment rod locked in position by prisms on horizontally movable plates
Inventor: GREINER OTTO
IPC: A47C20/04
Filed: 1974-02-25
Abstract: The bed frame comprises seat and back members which are connected together by a hinge wherein the back rest is infinitely adjustable by increasing the pressure and can be locked in position by means of a rod which is clamped between the edges of two prisms running in the longitudinal direction of the bed. These prisms are attached to plate-like elements which are mounted horizontally displaceable in a housing and are pressed against the rod by means of further elements which are mounted in the same housing and exert pressure in the longitudinal direction of the housing by rotating one of the latter elements. The prisms which clamp the rod are mounted loosely in grooves and are not fixed so that at the beginning of the clamping process the rod tries to draw along the edges of the prisms thereby increasing the clamping effect.

Title: Active filter ccts with amplitude limiting characteristics - designed for receiver ccts where input signals can vary widely
Inventor: SCHNEIDER GERNOT
IPC: H02J13/00
Filed: 1974-05-21
Abstract: Several active filter circuits are described which have certain amplitude limiting characteristics in addition to their filtering ones. These are suited to radio and telecommunications receiver circuits in which a wide variation in input signal amplitude is to be expected. When a very large signal is applied to the filter the output amplitude and duration are both limited so that saturation effects are almost negligible. The feedback network to the inverting input consists of a T configuration of capacitances and resistances. In one case the output is directly limited with parallel zener diodes. The low pass filter has a T configuration network applied directly to the input which is applied via a resistance to the non-inverting input.

Title: Effluent purification plant - incorporating sludge dewatering unit between aeration and sedimentation tanks
Inventor: WEBER WERNER DR ING
IPC: C02F11/121
Filed: 1974-10-04
Abstract: In the two-stage activated sludge purification of effluent by converting dissolved impurities into separable sludge in a first stage and separating this in a second stage, a part of the separated sludge being recycled to the first stage, the sludge separation is achieved at least partly by mechanical partial dewatering, the filtrate so produced being pref. subjected to sedimentation and the resultant sediment then recycled to the mechanical dewatering step.

Title: Cathode ray storage screen tube - has increased storage time from intermittent electron flow and has bistable storage screen with unstable secondary emission curve
Inventor: SCHELLENBERGER KARL
IPC: H01J29/98
Filed: 1975-03-27
Abstract: A method for increasing the storage time of a cathode ray tube with a bistable storage screen involves means to generate flood electrons in which the secondary emission curve shows a point of instability (1) whence the binstable effect derives. The electrons are fed intermittently to the storage layer in such a way that the secondary emission ratio of the part of the target not hit by the recording beam remains below the point of instability. The intermittent feed of electrons can be produced by a circuit in which a barrier electrode shutting off the flood electrons is fed by a keying stage fed from a multivibrator.

Title: Hydrostatic drive electronic control circuit - uses FET as part of circuit to keep product of speed and torque constant
Inventor: FEHN NORBERT ING GRAD
IPC: F03C1/40
Filed: 1975-08-02
Abstract: A constant voltage is applied to the terminal (1). A signal, the voltage of which is proportional to the pressure in the hydraulic transmission system, is applied to the terminal (7). This signal is transmitted through the resistance (R9) and the amplifier (V2) to the gate of the FET (T1). By correct choice of the magnitudes of the resistances (R6, R7, R8) the output from the FET (T1) can be made proportional to the product of the pressure signal voltage and the speed signal voltage. This output is transmitted to the control terminal (6) and controls the speed of the drive so that it varies inversely as the torque. This ensures that the power demand on the engine remains constant.

Title: Servo operated driving mirror - with split threaded sleeve held together by spring to form torque limiter
Inventor: SEBALD WALTER
IPC: B60R1/072
Filed: 1975-10-22
Abstract: The drive between the driving mirror mounting and the electric servo motor is by a torque limitting coupling, to prevent damage to the mirror mounting. The coupling has a threaded sleeve in two halves which are splayed apart when the torque exceeds a set value. The two halves are held together by a spring cage which is either rectangular or circular in cross section. This provides a simple assembly and allows the drive to operate without a large torque drag when reaching the end setting. It is simpler to fit and operate than a slotted sleeve.
