Title: Internal construction of automatic selling machine - uses gravity feed for spherical objects eg tennis balls
Inventor: KIEFER JOSEF
IPC: G07F11/34
Filed: 1975-02-14
Abstract: The internal construction of a simple automatic selling machine for spherical wares such as tennis balls, is presented. The mechanism holds the balls in a column so shaped that each ball is fed into the extraction mechanism by gravity and only one ball is extracted at each purchasing operation from the foot of each column. This column tract (5) is shaped in a zig zag fashion. Each tract is spot welded between vertical plates (3), so that magazines of such tracts can be built up, side by side, and a number of tracts can exit into a single drawer at the bottom. In this way, typically three tennis balls can be purchased simultaneously. The drawer mechanism contains a simple latch released by coin insertion.

Title: Warning signal system - has sensors along track sections emitting signal voltages for receivers and sectional logic stage
Inventor: KUECH FRIEDRICH DR RER NAT
IPC: B61L23/06
Filed: 1975-02-22
Abstract: Sensors emit signal voltages for alarm signals within the section to be monitored when vehicles enter their area of response. Two or more sensors are fixed along the track a short distance from each other and they respond to seismic and magnetic effects of the vehicles. The sensors respond in secession and in parallel. With parallel or series operation of sensors independent of vehicles the operating state is tested and test signals emitted by the sensor are characterized by a short response time which does not occur with vehicles. Receivers (R1, R2) and a logic stage (L3) are located in the track section (Fa).

Patent DE-2527886-A1 (DE)
Title: Resin surface impregnation, esp. by vacuum press, of articles - by applying a catalyst (mixt) soln. or dispersion to the article prior to the resin coating
Inventor: LOTTANTI GIUSEPPE DR
IPC: H01F41/00
Filed: 1975-06-23
Abstract: Before articles intended for use in medium and high tension technology, are impregnated, esp. by a vacuum-pressure-impregnation process, with a fluid which polymerises into a synthetic resin, so as to cover their surfaces, and/or fill in any pores and joints; a catalyst or a mixture of catalysts is applied as a solution or a dispersion to the surfaces, pores and joints, in such a quantity, that, at the appropriate temperature, the resin-forming reaction of the impregnating fluid is considerably accelerated. Zones of te objects which are to remain free of resin are masked with a protective lacquer before or after the application of the catalyst, which may be removed before or after impregnation takes place. The polymerisation process takes place primarily and rapidly, only in the zones where it is necessary, and in the zones where a rapid reaction is not desired, takes place slowly. The insulation given is without cavities and air holes, and is proof against leakage up to the predetermined operating and test tensions. Screws and tapped holes remain clean.

Title: Seat belt mounting for two door car - with lever to lift loop above door line if seat tipped
Inventor: SEIFFERT ULRICH DR ING
IPC: B60R22/02
Filed: 1975-07-12
Abstract: The front seat of the two door car has the bottom two mountings of the seat belt fitted to the seat frame to allow adjustment of the seat position. The upper mounting is fitted to the door pillar. The shoulder belt is located at the top of the seat back by a loop fixed to a linkage inside the seat frame. When the seat is tipped forward the loop is raised by the linkage operated by the seat hinge or by a servo motor. This raises the seat belt loop over the level of the door and allows unimpeded access to the rear seats. The belt end slides on a rigid lever which is extended by a crank lever as the seat is tipped, to maintain the belt loop level.

Title: Faultless transmission of binary coded signal words - includes synchronisation word within pulse train frame
Inventor: ERLAND JOHN JONSSON DIPL ING
IPC: H04J3/06
Filed: 1975-09-24
Abstract: At the sender end bits in the synchronisation word (s) are inverted in each pulse train second frame (F') in order to transmit two alternate synchronisation structures (S... S and S ... S), in which the information words (X, Y, Z) are contained and repeated. At the receiving end a number of bits in the transmitted pulse train equal to that of bits in the frame plus the number of bits in the synchronisation word are continuously stored. Bits in the two alternate synchronisation structures are compared, and when a minimum number of bits in the two structures correspond to each other, information words are read out.

Title: Bearing end face grinder for cranks - has grinder advanced to bearing dia. and oscillated between opposed flat faces
Inventor: SCHEMEL ROLAND
IPC: B24B7/16
Filed: 1976-06-23
Abstract: The grinding wheel (11) is fed in at right angles to the axis of rotation of the workpiece (12) to its smallest dia. After this, the grinding wheel is oscillated between the two opposing flat faces, so that the sides of the wheel cut these faces. The side faces of the grinding wheel are dressed for this machining operation. The side faces of the grinding wheel are dressed in such a way that they cut without a clearance angle. The width of the wheel is chosen so that it allows for dressing and grinding-wheel wear. The width after dressing is so that allowance is made for the amount of wear during cutting. During dressing, the wheel is moved axially between two dressing wheels (13).
Patent DE-2629143-A1 (DE)
Title: Synthetic material thermal insulating foil - has light reflecting metallic layer covered by varnish contg. colour to reduce visible reflection
Inventor: PUSCH GUENTER DR ING
IPC: F16L59/08
Filed: 1976-06-29
Abstract: The thermal insulating material comprises a foil of synthetic material to which a reflective metallic layer has been applied by vapour deposition. To avoid oxidation, the metallic layer is protected by a layer of varnish. The varnish contains a soluble colouring agent which is only active in the visible part of the spectrum. The varnish does not absorb radiation in the infrared part of the spectrum and the mirror-like reflectivity of the foil is reduced without affecting the thermal insulating properties of the foil. The foil is then more suitable for surface applications where visible reflection can be disagreeable.

Title: Telephone exchange reversed charges system - uses extra code dialled before called number which transfers charge pulses, with agreement of called party
Inventor: ESSLINGER FRIEDRICH
IPC: H04M15/08
Filed: 1976-10-21
Abstract: The system has the facility for charge transfer to the called subscriber, which is normally the responsibility of the calling subscriber. When the called subscriber accepts the charge transfer, he operates a device allocated to his line, which sends to a signal to a switch in the change bu which transmission of charge pulses to the calling subscriber is stopped and transferred to the called subscriber. The calling subscriber who wishes to make a call charged to the called subscriber dials a special code before dialling the called subscriber number. A device behind the counting pulse generator is looped in. It signals to the called subscriber to wish for charge transfer. Signal transmitted now by the called subscriber to the special device confirms the acceptance of the call, and the charge pulses are now sent to a store located to the called subscriber.

Title: Stereo sound reproduction system - employs three separate transducers with two transducers carrying same channel to give stereo effect in three different positions
Inventor: LEPPER WILHELM DR ING
IPC: H04R5/02
Filed: 1977-02-12
Abstract: In an arrangement of sound transducers for reproduction of stereophonic sound, three loudspeakers are used in place of the usual two. One sound channel is radiated by two of the speakers, (1), the planes of which are arranged at an angle of 90 deg. - 180 deg. (preferably 90 deg.-120 deg.). The second channel is radiated by a loudspeaker (2) placed on the bisector of the angle between the two loudspeakers. The sound transducers may be mechanically linked to oen another and placed around the head of the listener. In another arrangement they may be mounted in or on a table top. The advantage of the three-transducer system over the conventional system is that stereophony may be experienced in three separate listening positions.
