Title: Automat ensuring release of only single tray per coin stack - has interlock unit controlled by permanent magnet and armature coupled to counter-balanced sensor arm
Inventor: PFEIFER ADAM
IPC: G07F5/04
Filed: 1978-12-02
Abstract: A coin-operated dispensing machine incorporates an automatic interlock to prevent operation of the dispenser tray unless the correct coin has been inserted. Operation of the machine is effected by insertion into a slot within a carriage (2) that is then pulled forward far enough for the coin (3) to drop through a slot. In this position the dispenser tray is effectively blocked from being accessible by an interlock mechanism (6). The interlock unit is controlled by a permanent magnet (11) and armature (12) coupled to a counter balanced (14) sensor arm (7). In the interlocked position the sensor arm is held high. Only when the correct coin is inserted is the sensor arm caused to swing downwards. This releases the interlock mechanism and allows the dispenser tray to be pulled forward to the access position.

Title: Altering the width of slabs during continuous casting - where chill frame possessing the new width required is placed in mould, so narrow mould walls can be adjusted to new width
Inventor: HASHIO MORIO
IPC: B22D11/08
Filed: 1979-01-29
Abstract: The mould consists of two long side walls between which two narrow walls can be moved to vary the slab width. When a change in width is required, the feeding of molten metal via a casting pipe into the mould is stopped, and the slab is drawn out of the mould until only a small amt. of the melt remains in the mould; drawing is then stopped. A frame is then located in the mould to form a chill in the remaining melt, and molten metal is fed into the frame, the width of which corresponds with the new slab width required. After a solid skin has formed inside the frame, the narrow mould walls are moved inwards or outwards so they butt against the outside of the frame; and casting with the new slab width can then be continued. The width of the slab can be increased or reduced without the danger of a run-out, and within a min. amt. of time.

Title: Paper-making stock inlet - has a tube segment to adjust build=up level
Inventor: BINTER KARL
IPC: D21F1/02
Filed: 1979-02-03
Abstract: To control the height of the material build-up in the stock inlet of a papermaking machine, a tube segment is rotated to adjust the level. Pref. by rotating the tube segment, the height, volume and flow speed can be varied between the perforated rollers. The overflow runs over a narrow edge of the tube segment, and back across the whole width of the stock inlet. A thin scraper blade is pressed against the tube segment as a seal, with a higher pressure than the pressure in the stock inlet. The design prevents fibre build-up which would affect the appearance of the finished paper, and allows an overflow.

Title: Space wave error free radio direction finder - switches frame aerials in coaxial or coplanar configuration to give desired null points
Inventor: DONATH BERNHARD
IPC: G01S3/08
Filed: 1979-11-15
Abstract: The direction finder consists of a horizontal beam (2), rotatable about a vertical axis (1) at the ends of which are mounted the cross frame aerials (3,4: 3',4'). Switching the frame aerials (3,4: 3'4') together in one circuit arrangement, results in a coaxial double frame configuration and in another circuit arrangement a coplanar double frame configuration, both formed from the virtually one surface frame aerials (5,5' 6,6') respectively. By the opposite switching of two frames in either the coaxial or coplanar double frame arrangement, sharp null positions displaced by 180 degrees are obtained, (in contrast to the differential switching of two rotary beam aerials, as with an Adcock), and also additional null points, which arise from the null points of the individual frame aerials. The desired null points can be displayed on an oscillograph in polar or Cartesian coordinates- pref. the latter - ensuring that the unambiguous determination of both sharp null positions can be obtained using the most suitable double frame aerial arrangement independent of the polarization.
