Patent DE-2519043-A1 (DE)
Title: Safety wheel rim for tubeless tyre - has asymmetrically deeped rim edges for easier steering when deflated
Inventor: MULLER KURT
IPC: B60B19/00
Filed: 1975-04-25
Abstract: The wheel rim for the tubeless tyre has a deep profile to prevent the tyre from being torn off the rim when deflated. One side of the wheel rim has a deeper edge to form a protruding rim if the tyre is deflated (9). In this case the drag of the tyre is confined to a small band so that the steering force is not increased too much. This enables the driver to regain control of the vehicle in the event of a sudden blowout on the front tyre. The rim is set at an angle and can be formed by a bolt-on rim on the inside of the wheel, which reinforces the rim to take the extra weight as the tyre is deflated.

Title: Bolt attachment for mine support frame - has anchor ties spanning frame interval with one end threaded for U-clamps
Inventor: SCHAEFER HEINRICH
IPC: E21D11/28
Filed: 1975-05-02
Abstract: The strutting for I section mine supports is formed from spacer bolts anchored to the support frames on the underneath side with the bolt ends cranked to bridge over the flanges of the respective support members. The anchor ties (6) span the interval between adjoining frames (1), are hooked (7) at one end and at the far end are threaded (8) to accept U clamps (9) for grasping the frame flanges (5), with the aid of locknuts (11). Eyebolts (12) fitted on the anchors or the frames themselves have their shafts (14) run through holes (15), in the spacer bolts (14) and are secured to these through interposed bearing plates (17) with the assistance of locknuts (18). The plates should extend from the spacer bolt location into the cranked end area (3) and thus close to the frame stay members (2).

Title: Adjustable volume supermarket trolley - with height adjustable floor insert and reset control for stacking
Inventor: BERBIG ROLF
IPC: B62B3/14
Filed: 1975-05-09
Abstract: The floor of the basket of the supermarket trolley is formed by a tray insert (13) which is linked to the rest of the basket by vertical guides (11) and springs (17). The relative depth of the tray insert is adjusted by a ratchet (16) on each side of the basket. This enables the operator or user to adjust the basket to take either a large load, or a small load with improved access. The front of the basket is fitted with a control bar (23) linked on each side to a control lever (23) which opens the ratchet when pressure on the front bar is exerted. This releases the ratchet and allows the tray to spring upwards under spring (17) pressure. As the baskets are stacked they are automatically reset to the shallow position.

Title: Convertor for levels of digital signals - is for matching output of one family of switching circuits to inputs of another family
Inventor: HEISS LUDWIG ING GRAD
IPC: H03K19/018
Filed: 1975-09-23
Abstract: The converter is connected to two different potentials, which set its output signal to one or the other potential level, depending on a digital signal applied to its input. The first and second potential (P1, P2) can be applied to the output (A) through a first or a second output transistor (T4, T5). Conducting state of one output transistor (T4, T5) determines the blocked state of the other (T5, T4). Connection of the first potential (P1) and of the second potential (P2) to the output (A) is made through low resistance resistors (R4, R5), and a potential different from (P1, P2) is applied to the convertor input (E).

Title: Hierarchical multiple stage storage system - designed for multiple program processor avoiding multi-paging errors by overflow page buffer
Inventor: SCHNEIDER PETER DR PHIL
IPC: G06F12/0802
Filed: 1975-09-30
Abstract: A hierarchical multiple stage storage system for a data processing system capable of conducting several simultaneous operation sis designed and operated to avoid multiple page errors. Such errors occur when several active processes running simultaneously use a relatively large number of store pages and access several common storage modules. The lowest hierarchical stage is the main store contg. charge coupled devices, the next highest stage being a page buffer contg. page stores corresp. to main storage modules. All store loops in a module are shifted synchronously, their homologous loop position contg. a page store. To avoid multiple page errors the page buffer has an associated overflow buffer which receives pages from locations in the page buffer required for demanded pages not present. Both buffers are accessible in parallel.

Title: Percussion instrument for diagnostic and testing purposes - includes rod which is magnetically retracted against spring pressure and released when current is manually or automatically disconnected
Inventor: GUDAT HORST DR ING
IPC: B06B1/04
Filed: 1976-04-23
Abstract: Well defined, constant mechanical shock pulses are generated singly or periodically, independent from the distance to the tested object. A movable metal rod is magnetically pulled against a helical spring pressure. When magnetising current is switched off, rod is accelerated by the spring and after release from the spring is horizontally guided in nearly free from friction bearings, hits the tested object and bounces off it more or less elastically. The magnetising coil current is automatically reconnected, the bar attracted by it and held at a certain stop until the current is manually or automatically disconnected, controlled by a suitable electronic circuit.

Patent DE-2620582-A1 (DE)
Inventor: HEDLUND BO PAUL SIGVALD
IPC: F01M1/02
Filed: 1976-05-10
Abstract: The device serves for feeding lubricant to a lubrication point in the cylinder wall of a piston engine. A lubricating oil pump (15) feeds a pressure accumulator (16). A control valve (35) is connected to this, which intermittently opens a connection between the pressure accumulator and the lubrication point. A driver (32) limiting the suction stroke of the pump piston (22) is driven by a shoulder (34) of the accumulator piston (30), thereby limiting the pump capacity so that only the volume of lubricant consumed is replaced. A metering unit with a metering valve, which functions with two pressure levels, that is one at which lubrication occurs and one at which the metered amount is recharged, is located between the control valve and the lubrication point. <IMAGE>

Patent DE-2635288-A1 (DE)
Title: Linear inductive armature displacement transducer - has series connected inductances driven from constant frequency source
IPC: G01D5/20
Filed: 1976-08-05
Abstract: The inductive transverse-armature distance measuring circuit comprises an arrangement in which the total inductance is made up from a series-connected pair of inductors. One is constant and independent of the displacement. The second inductance is inversely proportional to the air gap (Lx). The inductors are fed with an alternating waveform so that the voltage across the variable inductor (Ux) is held constant throughout the measuring range. In series with the constant frequency, constant amplitude generator (11) is a capacitor (C) of such value that the series current (I) is essentially determined by the variable inductor. The current is therefore proportional to the armature displacement.
