Title: Metal animal trap for rats and mice - has top and bottom part held together by notch bearing and tension springs and is released by pressing together handles
Inventor: ERMECKE ALBIN
IPC: A01M23/30
Filed: 1976-05-25
Abstract: The animal trap, especially for rats and mice consists of a top and bottom part which are stamped out of sheet metal and held together by a notch bearing (3, 4) and by one or more tension springs. The top and bottom parts can turn with respect to each other, and handles (10) are formed on the catching edges at the opposite ends. The captured animal is easily released without touching the catching edges by easily pressing together the two handles. When the floor is smooth, the trap can be set up so that the catching edges stand downwards and the handles stand upwards.

Title: Board game with football theme - has interconnected dots arrayed in squares on surface to define movement paths for ball and player markers
Inventor: SPEICHERT MARTIN
IPC: A63F3/00
Filed: 1976-10-26
Abstract: A game board which represents a football pitch, is divided up into a regular number of squares. Each square is also provided with the two diagonal lines. Each crossing point of diagonals or square lines denominates a position where a playing marker can be placed. Each player uses eleven markers to represent a football team and the football is also shown as a marker of neutral colour. By throwing a dice, it is detrmined how many spaces a player marker can be moved along the connecting playing lines. When a player marker reaches a position that it occupied by the football, the football marker may be moved the same number of spaces towards the opponents goal.

Title: Shaving method without water, soap, brush or electricity - uses special skin cream and razor is held at correct angle
Inventor: KEMPF WILLY
IPC: A45D27/00
Filed: 1977-04-09
Abstract: A special skin cream known as WIKE 77 (RTM) makes it possible to shave without using water, soap, shaving brush or electricity. The cream is spread over the beard, the amount used depends on the amount of hair. The blade of the special razor known as Gillette Parad (RTM) is set with a hammer so that it will shape without cutting the skin. The razor is then held so that the edge of the blade is inclined at an angle to the direction of the movement of the razor as it is moved downwards over the beard. A second stroke is then made by moving the razor against the direction of growth of the hair. This second stroke gives a very close shave. The surplus cream is then removed with a tissue.

Title: Circular rubber mounting for filter sleeves - having good electrical contact to filter housing to provide earthing with flammable dusts
Inventor: RACHOR ALFRED ERNST ING GRAD
IPC: B01D46/02
Filed: 1977-08-16
Abstract: Mounting is for filter sleeves for filters with round or rectangular construction using pneumatic cleaning and having assembly from the top. The upper seam of the filter sleeve has an elastic ring sewn into it with circular cross section and having a stiffening wire. The mounting serves to compress this to give a dust tight seal. The sleeve contains a steel basket support on a tubular mounting. A plate projecting from this serves to compress the seal. At the same time this is achieved by screwing down a cover from above, which has good electrical contact with the housing. Used esp. with combustible powders. To prevent explosion, the elements have to be earthed. The system allows a simple means for this.

Title: Automatic engine cold starting system - has pull link engaging movable bearing bolt of bimetal spring
Inventor: VOGLER GUENTHER
IPC: F02M1/10
Filed: 1977-10-21
Abstract: The automatic cold-start system is for an engine carburettor, having an emitter reacting to an engine operating temperature. This preloads and adjusts a disc having three or more notch positions and forming an idling stop for the throttle butterfly. This increases the air gap left by the latter with reduced engine operating temp. as compared with normal warm air temp. as soon as a starter lever coupled to the butterfly is moved in the open direction and releases the disc. A pull link reacts to the vacuum in the intake after the butterfly, its stroke being such as to adjust the disc by one notch away from the staring position when the engine fires. The pull link (14) engages with the movable bearing bolt (12) of the bimetal coil spring (11) forming the emitter.
Patent DE-2752856-A1 (DE)
Title: Continuous crystallisation process - has several crystalliser units in series with counterflow through them and rising flow classification in crystal outlet (NO 27.12.77)
Inventor: MUELLER TORE BERNHARD
IPC: B01D9/02
Filed: 1977-11-26
Abstract: Crystallisation process contains a series of stages in each of which partial crystallisation occurs. The mixture enters a separation stage, as it leaves the final stage. There is a separation between fine crystals and the coarser ones required as product by maintaining an upwards velocity of feed liquor in the crystal outlet passage. The coarse crystals from each stage are fed back to the previous stage on that there is a gradual growth of crystals from one end of the process to the other. The crystal product is taken off in equilibrium with the saturated feed liquor while the spent liquor leaves from the other end of the process. Used for industrial crystallisations esp. of Al(OH)3. The process is simple and economic, it gives a uniform product of reasonable size and is not sensitive to other process variations.

Title: Agricultural implement combination with support frame - can be moved into working and transport positions via hydraulic wheel axle lift
Inventor: BARLAGE BRUNO ING GRAD
IPC: A01B63/22
Filed: 1977-12-09
Abstract: The agricultural implement combination has a support frame, which can be suspended on a tractor-vehicle via a towing device at its front end. It is supported on the ground for transport via wheels which are arranged on a camera wheel shaft. In front of the wheels is a soil working implement such as a breaker or packing roller, and this supports the support frame instead of the wheels during operation. There are also connections for further agricultural implements. The wheel shaft (6) can be adjusted in height with respect to the support frame (1) by means of a hydraulic lifting device (12). This height adjustment is used to lift the support frame and the attached implements (15, 18, 19, 22) from a operating position into an upper transport position.

Title: Echo suppressor for long-distance telephone connections - uses computer to calculate compensation echo signals and adder forming residual echo
Inventor: LIST JUERGEN VAN DER DR ING
IPC: H04B3/23
Filed: 1978-04-17
Abstract: The echo suppressor has an A/D and a D/A converter, two shift registers, a correction circuit for the coefficients of a transversal filter, a folding computer to calculate a compensating echo signal and an adder to form a residual echo as the difference between the compensating and actual echo signals. One of the registers stores the filter coefficients and co-operates with a multiplier to form the product between samples of the residual echo and the values of the received signal stored in the second register. An adder sums the second register's contents. A divider forms a weighting factor. Another multiplier forms corrections for the filter coefficients. An adder forms the updated, corrected filter coefficients.
