Patent DE-2456351-A1 (DE)
Title: Microwave module substrate holder - has clamp or bolt holding substrate onto flat spring contact plate on earthed housings base
Inventor: HENZE WINFRIED ING GRAD
IPC: F16B5/06
Filed: 1974-11-28
Abstract: The microwave module substrate holder clamps the ceramic or glass substrate (4) onto the base of the microwave module housing by the overhang of a retaining block (2) or screw head. A spring contact plate (5) is located between the base and the underside of the substrate and pushes the latter upwards against the overhang. The retaining block is linked to a recessed bolt or nut (6) which pulls it down onto the substrate. Alternatively, a simple bolt may be used to clamp the substrate down onto the base. The advantage of the assembly lies in its giving a robust earth conection to the substrate ground plane and in easy dismantling.

Title: Exhaust gas from e.g. IC engine purifcn. - by contacting with fast moving liq. mist and decelerating mixt.
Inventor: STEIN HEINRICH
IPC: F02B1/04
Filed: 1974-12-03
Abstract: In a process for purification or neutralisation of gases contg. harmful contaminants, a liq. mist is formed which is accelerated in a preferred direction and brought into contact with the gas to be purified. The mixt. of liq. and gas is then sharply decelerated to bring about at least, partial absorption of the gas or the contaminant by conversion of kinetic into potential energy. The liq. is finally collected. The process provides a simple method of gas purification, having low construction costs and minimum maintenance requirements.

Title: Continuous lamination of thermoplastic foils - by looping foil and substrate under longitudinal tension around heated roll
Inventor: SCHWINGES KURT
IPC: B29C43/30
Filed: 1975-01-30
Abstract: The foil and the substrate or fabric strip used to produce the laminated product are united under the influence of longitudinal tension and the action of heat, bonding taking place at a temp. at which tensile stress is produced. The components of the laminate pref. encircle the heated bonding roller for >=270 degrees C and the bonded laminated is drawn off the bonding roller onto a smaller take-off roller which has a higher circumferential rate of rotation so that the components are subjected to the same tensional forces. The bonded material is only withdrawn from the take-off roller which rotates in the opposite direction to the heated roller when it has cooled down. Minimal attention during bonding by the operator is required.

Title: Mortice lock with double turn actuation - has additional locking element which becomes active only on second turn
Inventor: EICKEN HEINZ TEN
IPC: E05B63/00
Filed: 1975-02-13
Abstract: The lock especially a mortice lock is used for doors with frames made from hollow profiles. The lock has latch actuated by a number of turns. The first turn does not actuate an additional locking mechanism and this reduces wear of the lock. The lock becomes more difficult to pick when it is rotated twice on locking. The additional locking element (41) is pivoted on the latch (8) and, on rotating the key twice, it is moved from its spring loaded rest position into the locked position. This element is also held in the locked position by a spring. The locking element (41) is provided with two locking surfaces which are angled to each other.

Title: Axial bearing arrangement for pump motor - has ceramic journal ring which provides thrust arrangement with carbon bearing
Inventor: HALM RICHARD
IPC: H02K5/167
Filed: 1975-03-20
Abstract: An axial bearing arrangement for small motors, for example as used on circulating pumps in central heating systems. The bearing between pump and motor comprises a hard ceramic journal ring (6) which works in conjunction with a carbon bearing on the pump housing to give a thrust arrangement. A face (10) is machined on the end core punching perpendicular to the shaft to give a true seat for the ring (6). The outer surface of the ring has a groove into which the metal at the bore of the short circuiting ring (3) is deformed by swaging or riveting. The ceramic ring is thus located axially and also runs true axially.

Title: Extensible cylindrical silo sheath panel insertion - has spirally wound cover lift and rolled on slope
Inventor: KOLLER HANS
IPC: E04H7/06
Filed: 1975-05-15
Abstract: The process is used in construction of a cylindrical sheath for an upright storage tank, silo or other container made up from interconnectable panels. It has a base component, with a ring attached which has a top helically lined edge, and a cover with a ring with a corresponding bottom edge. Space for added panels can be provided by staged displacement of the cover along the helical line. This displacement of the cover component is carried out by a process of linear lifting and simultaneous rolling motion, effected by virtue of its own weight, on a surface which is inclined relative to the slope of the helical line. This can be done in a rapid rhythmic sequence until enough space has been gained for insertion of a new panel. Less power is needed, and plate edges are better preserved.

Title: Coded character recording and reproduction on TV - using audio frequency coding and reading from character generator into shift register
Inventor: SCHROEDER WOLFGANG DIPL ING
IPC: G11B20/10
Filed: 1975-08-27
Abstract: The recording system is based on conventional tape or cassette recorders as the address memory for the store of a character generator. The address signals of the printed lines of the text are coded in a parallel or serial bit mode depending on their high and low levels, together with the clock signals, in an FM modulator or start-stop oscillator in an a.f., and recorded. They are reproduced in a selection and demodulation circuit as bit-parallel or bit- serial address signals and clock signals. The characters can be read out from the character generator and read into a reproduction shift register. The read-out clock frequency for the mosaic characters of the character generator is synchronised with the line and image deflection pulses of a TV receiver to produce the information as a line at the desired spot.
