Title: Stereo record player pickup - scans two 45 deg. stereo recordings and has two flat ceramic flexural transducers
Inventor: SCHAMBERGER JOERG
IPC: H04R17/08
Filed: 1973-06-20
Abstract: The longitudinal axes of the transducers are parallel to the sound groove; they are held by their rear ends in an elastic support, and their front ends are connected to a common stylus through a coupling element. The elastic support is such that each transducer clamping is effective in the transducer length direction over the whole clamped area, but in the transversal direction only over a part of its width. The elastic support consists of a block with hollows forming a V for insertion of the transducer; a further hollow separates the support from the housing in which it is held; this further hollow is such that resetting torque for each transducer when rotated in one direction is 4-5 times higher than in the opposite direction.

Title: Magnetic impulse metal shaper - twin coil concentrator has low inductance terminals
Inventor: FERTIK SAUL MARKOWITSCH
IPC: B21D26/14
Filed: 1973-06-23

Patent DE-2338697-A1 (DE)
Title: Temperature controlled valve for water heater - overloading of input expansion bellows when subjected to temperatures outside range is avoided by slip mechanism
Inventor: REIMERS ERNST
IPC: G05D23/13
Filed: 1973-07-31
Abstract: A flow control valve is actuated by an expansion bellows input stage that responds to variations in temp. In the closed position, when subjected to maximum temp., an outer annular ring seal is held against a seating by a combination of spring action and expansion of the bellows. If the maximum temp. is exceeded a centrap piston moves relative to an intermediate sleeve, thus avoiding any overloading of bellows. When the temp. falls, the annular seal leaves the seating and eventually contacts a stop when the minimum temp. is reached. If for any reasong a temp. lower than the required minimum is encountered, the central piston again begins to slip relative to the sleeve. Again overloading of the expansion bellows is avoided.
Patent DE-2339105-A1 (DE)
Title: Film guide element for roll film camera - has fixed curved outer surface radiused over 90- deg to avoid sharp corners on film
Inventor: SOMMERMEYER FRIEDRICH
IPC: G03B19/04
Filed: 1973-08-02
Abstract: The film guide is designed to turn the film coming from the spool in the camera or cassette through approximately 90 deg. into the exposure plane. The radius of the guide curve is similar to the natural curvature acquired by the film on its spool and approximately four times larger than that of the usually used rotating guide spindles. The curved surface consists of a dense polished low friction plastics material. The guide is movably mounted to allow easy film threading. It has side flanges overlapping the edges of the film for accurate guidance.
Patent DE-2344116-A1 (DE)
Title: Varying pressure range connecting cone for compression fitting - has metallic reinforcement inserts for pressures above 700 lb/sq in
Inventor: SUESS HANS
IPC: F16L19/065
Filed: 1973-08-30
Abstract: A sealing cone made from an elastic material is compressed when a sleeve nut is screwed over the connector fitting. This deflects the tube section under the cone radially inwards without causing permanent deformation since the elastic limit of the tube material is not exceeded. For pipe line pressures above 700 lb/in2 the tapered faces of the sealing cone have supporting metal inserts. For the high pressure range, 1500-6000 lb/in2, the reinforcing element of the sealing cone is an integral coil made from wire with rectangular cross section. All three types of cones are identical in shape and size, thus only one type of pipe line fitting is required.

Title: Procedure for packing goods in foil - packing edges are joined by welded strip before foil is shrunk
Inventor: SCHMIDT KURT
IPC: B65B53/02
Filed: 1973-12-21
Abstract: Procedure for producing packing consisting of packed goods wrapped in shrunk thermoplastic foil by which a right-angular sheet of the foil is folded to form a half of a hose shape and the packed goods placed between its front and back sides. Thereafter the edges of the foil are welded together and the foil hot shrunk round the goods. The longitudinal edges of the packing are joined by overlapping welded strip of thermoplastic foil which when positioned is projecting with its ends over edges of the packing. During heating of the packing to shrink the foil the projecting ends of the strip are pressed on the packing surface and after the heating the completed packing is cooled.

Title: Drink bottle opener - removes metal top seal and collects in container used as handle
Inventor: HAGMEYER SEN MAX
IPC: B67B7/16
Filed: 1974-02-08
Abstract: The bottle opener for beer, lemonade etc. operates in the the customary manner by forcing the metal sealing cap upwards, away from the top of the bottle neck, in one easy hand movement. Normally the top is allowed to fall to the ground, table-top etc. to be collectively removed later. The present opener has an integral container into which the seals are collected. The seals are prevented from falling out when the opener is subsequently used by a one-way pivotable lid at the top of the container. The container is round so that it can conveniently be used as the handle. To remove the collection of seals the deformable container is squeezed to release the confining lid.

Title: Push-on valve cap with locking thread - seals the valve stem without screwing
Inventor: KAUF WALTER
IPC: F16K27/08
Filed: 1974-05-21
Abstract: The valve cap consists of metal or synthetic material, and has four parts, e.g. a valve cap sleeve, a locking part with locking thread, a locking spring, and a rubber seal. For positioning, the cap is held between two fingers. The locking part is pressed into the sleeve, and this causes the two thread halves to be moved away from each other. The locking spring is then positioned in round recesses of the sleeve and the locking part, causing the threaded halves to be pressed against the valve stem.

Title: Milking-machine with purification-device - has spray jets for cows' teats and connections to control and metering unit
Inventor: SCHWEIGER JOHANN
IPC: A01J7/04
Filed: 1974-09-14
Abstract: The cleaning jets are positioned in the milking stall so that the cows stand over them. A programmed circuit is switched on by a press-button. Hot and cold water flow to the purification device and are mixed by a mixing valve to a controlled temperature. The water is then carried through a pipe to the purification jets.

Title: Electronic contact operated by finger touch - has two operating circuits with key transmitting pulses to control circuit via diode
Inventor: BRUNGSBERG HEINRICH-JOSEF
IPC: H03K17/725
Filed: 1974-12-17
Abstract: The electronic contact switch state can be changed by touching shortly a key, resulting in the transmission of a pulse to a relay or reed switch which controls a load circuit switching contacts. Two touch keys (16, 17) in an operating circuit (III or IV) transmit when touched, positive or negative pulses to a control circuit (II), through diodes (14, 15) of opposite polarities. In response to these pulses an electronic power circuit closes or opens a switch, such as reed contacts (3, 4), or a relay with only one winding, transmitting the switching function to the load circuit (I).
