Patent DE-2416915-A1 (DE)
Title: Chromium plated cylinder bores for internal combustion engine - with microcrazed surface polished after heat treatment or mechanical treatment
Inventor: RETOLAZA IBARGUENGOITIA JUAN
IPC: F02F1/00
Filed: 1974-04-08
Abstract: A Cr plated surface is improved by subjecting a hard flat chromium-plated surface to a thermal treatment at 100-300 degrees C for several hours to develop or alter a microcrack pattern, followed by subjecting the microcracked surface to an abrasive polishing process. Used for polishing internal combustion engine cylinder linings. The lubrication properties of the linings are improved since oil can adhere to a roughened surface with depressions better than to a flat surface. The surface can be roughened with a more regular pattern than by simple grinding. Instead of heat-treating, tre microcracking can be produced mechanically by a grinding process. Both mechanical and heat microcracking can be used in combination.
Patent DE-2420170-A1 (DE)
Title: Ink droplet character printing synchronisation mechanism - synchronises droplet frequency with droplet deflection field
Inventor: GENSTHALER EDMUND DIPL ING
IPC: H04N1/23
Filed: 1974-04-25
Abstract: The writing speed is fixed by the drop frequency. Circuitry is provided to synchronise the droplet deflection system with the frequency in order to provide improved character definition and consistency. A bistable element is set by a character jump instruction signal and is reset by a signal indicating when no droplet is in the deflection system. Two NAND gates control the state of a 4-bit bidirectional counter with the outputs coupled in a NAND gate. The bistable and counter circuitry is coupled to NOR gates used to inhibit the transmission of drive pulses to the output. An additional bistable provides pulse shortening of pulses controlled by a conditioning signal. The circuit operation is such that a character jump signal produces a controlled delay in the transmission of pulses dependent upon counter state.

Title: Switching matrix with magnetically controlled contacts - has alternating source supplying winding rows and direct source supplying columns
Inventor: MISULOWIN LEONID YAKOWLEWITSCH
IPC: H01H67/24
Filed: 1974-07-22
Abstract: Switching matrix has magnetically controlled contacts for use in telephone exchange installations. It can function as the commutator system for the circuit incorporating the speech channel and transmission path for a discrete information signal. The matrix consists of rows and columns of electro magnets each with two coils operating a contact. There is a common input for each row and one for each column each derived from its own source. The first source (8) supplying the rows produces alternating current and the second source (10) supplying the columns produces direct current. The selected windings (2, 3) for the rows and columns on the particular magnetic rail (1) will be excited simultaneously by an alternating and a direct field.

Title: Plastic wrapped two-ply section of prepared chimney liner - insulation layer expands to fill chimney when plastic stripped off
IPC: F23J13/02
Filed: 1975-01-09
Abstract: The liner consists of a refractory tube (1) surrounded by an elastic layer of heat-insulating material (2) which is compressed down to half its volume by a plastic foil wrapper (4). The outer layer is displaced a little along the inner so that the finished joints will be staggered. The ends of the heat-insulating layer (2) are damp-proofed, and this, with the plastic wrapping, protects the unit sufficiently in transit. As the building work of forming the chimney progresses, the liner is inserted, section by section; the compression of the outer layer by the wrapping provides some clearance, so that it fits easily. When the section is in position, the plastic wrapper (5) is stripped off and the insulation expands into place.

Title: Pneumatically operated swimming-pool partitioning folding wall - with cavities flooded or air-filled for folding downwards or upwards
Inventor: BOEHM HANS-JOACHIM DIPL ING
IPC: E04H4/14
Filed: 1975-04-19
Abstract: The power-operated folding wall is for use in swimming pools, being utilised as a pool divider, and as a below-surface guard for adjustable elevating bottom sections. The folding, trap-opening, wall is made with hollow spaces at suitable points, and these can be either floorded with water or blown out with air. By this means flooding can bring about folding of the wall onto the pool bottom, while filling with air causes it to fold upwards into the vertical position. The air can emerge from nozzles in the bottom of the pool, and rise freely in the water to be conducted through correspondingly sited openings into the cavities in the wall. Valves can be opening for re-flooding.

Title: Portable folding tool for joining sheet metal - has grooves of unequal width on edges for clamping and folding
Inventor: PUSCH KARL-HEINZ
IPC: B21D5/16
