Patent DE-2358762-A1 (DE)
Title: Jointing ceramic tiles with plastic cements - having high filler to resin ratio and used as crumbly solids
Inventor: MUEHLBERG HEINZ-JOACHIM DR
IPC: E04F15/08
Filed: 1973-11-26
Abstract: Ceramic tiles are jointed with cementing compsn., based on organic plastic cements of acid-proof building, by introducing crumbly cement compsns., having a filler: resin binder mixing ratio 5:1 to 8:1, into the joints and compacting mechanically inside the joints. Consumption of plastic and labour-time are reduced. Use of crumbly solid jointing material, avoids deposition of soiling material on tile surfaces by the strongly adhesive plastic cements.
Patent DE-2405082-A1 (DE)
Title: Pressure cooker with extra safety lock - has movable bolt which splits up sealing surfaces to allow excess pressure to escape
Inventor: PULFRICH HORST
IPC: A47J27/092
Filed: 1974-02-02
Abstract: The pressure cooker is provided with an extra locking device between the lid handle and the pot handle which initially prevents the cooker from being opened. Undoing the locking device automatically results in the reduction in the excess pressure prevailing inside the cooker so that no harm can result. The locking device preferably comprises a locking bolt or hook which is displaceably mounted inside the lid handle and engages with a counter-member in the pot handle so that to undo the lock the bolt is moved in the direction of the seal between the pot and lid whereby a gap is formed between the two sealing surfaces allowing the pressure inside the pot to be reduced. A spring is preferably provided to ensure that the locking bolt cannot be accidentally moved.

Title: Arrgmt. for transformation of wave energy - into electrical energy by using a floating buoy with turbo generator
Inventor: BABINTSEW IWAN ANDREEWITSCH
IPC: F03B13/18
Filed: 1974-04-03
Abstract: The arrangement consists of a floating buoy which has a central tube of large diameter and which extends to well below the buoy. Weights are mounted at the bottom end of the tube to make the buoy stable. A piston moves up and down in this tube when the buoy rises and falls. The piston alternately pushes and sucks air through a turbine. A row of stationary guide vanes is mounted at either side of the turbine wheel. The guide vanes are shaped so that the air pumped by the piston is directed against the turbine in its direction of rotation irrespective of which direction the air flows. The turbine drives a generator which charges a battery via a rectifier and stabiliser.

Title: Piston type container filling machine - has pistons actuated by slides working between endless tilting tracks
Inventor: BUICK DOUGLAS STEWART
IPC: B65B3/32
Filed: 1974-08-23
Abstract: The substance to be inserted is contained in a reservoir, surrounded by parallel cylinders connected to it and outlets and containing pistons. Top and bottom endless tracks enclose the central reservoir, and the angle between their plane and the cylinder axes can be varied, thus causing the reservoir and the cylinders to rotate about the vertical reservoir axis. The machine is particularly for handling semiliquid commodities such as jam. Each piston is connected to the end of a pin protruding radially between top and bottom tracks, and which carries a sleeve sliding axially on it to a position in which it can be locked. Each sleeve carries slides working against the tracks.

Title: Connector between rigid and collapsible pipes - has cylindrical end tapering outward to avoid sharp bends in collapsible pipe
Inventor: DRUDE BURKHARD CARL
IPC: F16L11/12
Filed: 1975-03-17
Abstract: The connector is used to connect a collapsible pipe line to a rigid pipe. The collapsible pipeline is used e.g. to transport a fluid across the sea bed. The connector is made from metal and has longitudinal throughlet openings for the fluid. It is shaped so that at one end the connector fits tightly in the full dia. of the collapsible pipe, while the other end is tapered in such a way that the collapsible pipe cannot bend sharply. The connector is able to withstand the high hydrostatic pressures occurring on deep pipelines. By avoiding sharp bends the possibility of buckling occuring is reduced.

Title: Radar station with A-D converter in reception circuit - has threshold circuit for noise signals, and amplifiers with gain controlled by integrator
Inventor: SIEGEL HARALD ING GRAD
IPC: G01S7/32
Filed: 1975-07-10
Abstract: The radar station has at least one amplifier whose gain is controlled by an integrator in a branch circuit. Noise is converted in accordance with amplitude into multiple bit code word and applied to a threshold circuit (12) in the branch circuit. This circuit delivers for code words above a certain level a binary '1', and a binary '0' for code words below this level. These binary values (0, 1) are integrated in the integrator (13) provided and used for gain control. In many cases it can be serviceable to switch the branch circuit on as required instead of having a permanent connection. The switch (15) is provided expressly for this purpose.

Title: Molybdenum truing tool for diamond grinding wheel - has wheel mounted normally on machine and tool mechanically guided along required path
Inventor: KISH ISTVAN T
IPC: B24B53/00
Filed: 1975-09-11
Abstract: The process for turning a resin bonded diamond grinding wheel comprises turning the wheel (6) about its normal rotational axis (22) and holding a molybdenum tool (8) against its friction surface. The tool is of at least 95% purity molybdenum, which is produced by cold rolling. The tool is moved back and forth over a curved path (12) around the wheel periphery. This produces a curved work surface on the wheel edge. The molybdenum tool is pref. in tangential line contact with the periphery of the wheel. The tool produces less dust each heat than a rapidly wearing silicon carbide or aluminium oxide dressing tool.
Patent DE-2603012-A1 (DE)
Title: Ski safety harness with shoe spaced from sole plate - has central fixed peg and side cheeks held so that sole plate slides forward to free during frontal collision
Inventor: BIERMANN PETER DR ING
IPC: A63C9/085
Filed: 1976-01-27
Abstract: Safety ski harness has the boot fitted by a toe grip and releasable heel grip to a sole plate (11) which sits on support pieces (25) fixed to the ski (12). Side cheeks (13) grip the sides of the sole plate which side projections fit into grooves in the cheeks (13). A fixed peg (15) on the central support projects upwards to grip into a slot (14) in the sole plate (11). The side cheeks are pivoted so that in the event of a frontal collision the sole plate can slide forward. The fixed peg slides along the slot which widens and continues to the back of the sole plate to free the sole plate (11) from the ski. This lessens the possibility of the skier tumbling forwards off the ski through the toe being held in the harness after the release of the heel.

Abstract: A bottle vending machine has several dispensing positions for cylindrical bottles which can be of different sizes. Each dispensing position has an inclined support plate (5) sloping down to the actual dispensing point and carrying bottles lying two high on their sides. A transfer mechanism at the lower end of the plate receives the bottles as they roll into it one at a time. The transfer mechanism is pref. a half-shell which normally holds a bottle ready for sale. On insertion of a coin a motor is energized to rotate the half-shell and drop the bottle into a compartment from which it can be taken by the purchaser.
Patent DE-2604459-A1 (DE)
Title: Selection control circuit for telephones - is for PBX switchboard and delays disconnection in order to prevent trunk call interruption by local call
Inventor: BIRKL ALOIS
IPC: H04Q3/62
Filed: 1976-02-05
Abstract: Groups of extensions in the PBX are generally excluded from taking part in trunk calls. Any attempted by such extensions trunk calls are broken by corresponding disconnecting means controlled by at least one of charge pulses during conversation. The disconnection is delayed in order to allow connection to the calling extension of a message or signal. After the message or signal is applied, marking a trunk call, it prevents the disconnecting device from becoming operative. The logical circuit includes a NAND gate (G1) which receives one signal from the timing control unit (MK) and the other direct from the switchboard.
