Patent DE-2637725-A1 (DE)
Title: Prodn. of unattached zones in plastic coated substrates - by air cooling the extruded plastic at pre-selected positions
Inventor: HONKANEN ARTO DIPL ING
IPC: B32B7/04
Filed: 1976-08-21
Abstract: Extrusion coating of base material(s) e.g. paper, car board, forming a coherent strip, by means of a molten thermoplastic material in such a way that at specific positions in the resulting laminate, the coating material is not attached to the base material(s). For this purpose the thermoplastic material is cooled to such a low temp. at the desired positions prior to bending with the base material, that the coating material at these cooled positions is not bended to the base material during the coating process. Permits packing materials to be produced with free edges which can be bonded later to form a sealed package.

Title: Seamless, capillary, thin walled palladium alloy pipe mfr. - by drawing in stages to critical size with intermediate anneal
Inventor: GOLCOV VIKTOR A
IPC: B21C1/00
Filed: 1977-03-07
Abstract: Seamless capillary thin-walled vacuum-tight pipes are mfd. from Pd-based alloys by drawing and reducing a pipe billet by stages so that each time the cross sectional area of the billet walls decreases by 60-80%. Each drawing stage is followed by an anneal at 830 plus-or-minus 30 degrees C. After decreasing the thickness of the pipe walls to 0.24-0.30 mm the billet is agains drawn and reduced by stages, each time decreasing the cross section area of the walls by 28-50% and then annealing at 750 + 20 degrees C after each drawing stage. The pipes are employed as diffusion membranes, selectively permeable to hydrogen (isotopes) and serve as the working elements of diffusion filters for superfine purification of hydrogen isotopes. The pipes will withstand a vacuum of 10-3-10-4 mm Hg and remain vacuum-tight after 1000 hrs. of operation in hydrogen-contg. media.

Title: Time-controlled thermostat for radiator valve - has time block between thermostat head and valve to regulate operation
Inventor: SCHULTZ JOHANNES
IPC: F16K31/48
Filed: 1977-03-26
Abstract: The time controlled thermostat valve has a defined ideal temp. value which for a certain preselected time can be brought to a new level and readjusted to its original value after expiration of this time. A time block is interposed between the thermostat head and the e.g. radiator valve. By rotating the cap the threaded core is moved. Axial movement of the cap causes the follower pins to engage in the boreholes of the timing mechanism cam disc. After a preadjustable rotational angle a catch on the threaded ring drops into a recess of the threaded core during release of the ring relative to the housing.

Title: Security alarm for fence - has switch tripped by movement of spring supported Y=shaped top rail
Inventor: BLASER ERNST
IPC: G08B13/12
Filed: 1977-04-22
Abstract: The security alarm for a fencing system is designed to be triggered by any additional loading on a top rail. The Y shaped top rail (1) is supported on pins with associated coil springs (2). When weight is placed on the top rail e.g. by an intruder attempting to scale the fence, the rail deflects to allow an actuator (3) to trip a microswitch (6). The switch may be positioned to respond to a differential extension of the springs caused by sideways movement of the top rail.

Title: Gyroscope surveying compass with optical read=out - has compensation networks giving accurate performance with mirror, collimator and photosensitive detector array
Inventor: BALS EWALD ING GRAD
IPC: G01C19/38
Filed: 1977-07-29
Abstract: A number of signal compensation techniques are used with corresponding electronic logic and analogue networks. They are for use with an optically read out gyroscope survey compass. The optical readout of the gyroscope package, and thus of the compass, is via a mirror and collimator and a photosensitive detector array (D1, D2, D3, D4). The signals derived from this are combined by addition and subtraction, connected to digital format (18) encoded (20) and fed to a local computer (12). This contains a programmed algorithm designed to reduce disturbance effects by averaging the signal outputs over a predetermined period, taking into account temperature variations detected by a suitable transducer, amplifier (28) and the same digitising and encoding network.
