Title: Reactive power compensating capacitors control circuit - has triangle-connected thyristor and two diodes linked to capacitors by inductors
Inventor: KNUTH DETLEF DIPL ING
IPC: H02J3/18
Filed: 1979-02-09
Abstract: Simplified three-phase compensating capacitors switching minimising the number of thyristors and featuring inexpensive control uses a polygonal circuit. The latter comprises two diodes (D1, D2) and one thyristor (T1) which are connected to the compensating capacitors through series inductors (L1, L2, L3). The inductors limit the circulating currents during switching, while usage of a single thyristor is made possible by the blocking effect of charged capacitors when switching is carried out. In a two-stage switching version, there are two L-C series elements in parallel, with the star-point ends from one phase (R) connected to a thyristor, and from the other two ends with the common junctions between pairs of diodes connected in series.

Title: Coin accumulator track - has downward sloping track with stepped bottom and side wall for surplus coin overflow
Inventor: BARTH WALTER ING GRAD
IPC: G07F1/04
Filed: 1979-07-13
Abstract: Overflow of coins exceeding the accumulation section of feed channel in a cash register prvents jamming. The excess fed coins are thrown back into the return channel by the design of the feed track. The latter exhibits two inclinations, one in the downward direction for the gravity assisted rolling of the coins and the other one by tilt of the back wall (2). This ensures that the downward rooling coins bear against the wall (2) of the track. The inlet end of the track extends over a length slightly greater than the coin diameter with track bottom (1) featuring a width equal to coin thickness. Side wall step (3) and bottom track step (4) bound a further similar length with double-width track compared to coin thickness. This is followed by track bottom width equal to single coin thickness. The coins assembled up to step (3) are then equal to the number of coins required, any other coins being ejected from the step (4).

Patent DE-2942843-A1 (DE)
Inventor: FAIGLE HEINZ
IPC: F28F25/08
Filed: 1979-10-24
Abstract: The packing for apparatus for heat exchange and/or mass transfer between liquid and gaseous media is formed by individual plates, some of which are corrugated and which are assembled into packs. These packs have so-called standing plates (1''; 3') which protrude downwards and between which the so-called high-position plates (2'') are located. The lower edges of the high-position plates (2'') arranged between the standing plates (1'' and 3') define a substantially V-shaped contour. The predominant number of the lower edges of each high-position plate directly adjacent to a standing plate point away from the latter into the interspace defined by two standing plates. This measure ensures that the downwards-leading channels, which are as a rule very narrow, of the individual packs are reliably emptied and the liquid trickling down from the high-position plates trickles or drips off and is removed and taken away as reliably as possible from the standing plates, in order thus to optimise the transfer effect or cooling effect. Such types of packing can be used in cooling towers. <IMAGE>
