Patent DE-3724077-A1 (DE)
Title: Rotary pump or motor with external rotor
Inventor: STURM KARL
IPC: F01C1/46
Filed: 1987-07-06
Abstract: This invention concerns an additional invention to P 3638022.9 and P3724076.5 wherein, contrary to these inventions, the stator is the inner casing and the rotor the outer casing. This means that the semicylindrical elements are fitted into the outer casing, and must always be run along the inner casing at one edge. Inlet and outlet branches must also run into the inner casing. However, the possibilities for restricted guidance of the swivelling motion of the semicylindrical element are more restricted than if the semicylindrical elements are bedded in the inner part. <IMAGE>

Title: Extinguishing thyristors of railway or industrial power converter - using self-commutating rectifier across AC voltage terminals of main rectifier
Inventor: WALDEN PETER DIPL ING
IPC: H02M1/00
Filed: 1987-07-29
Abstract: Static power converter main branch thyristor extinction is based on using a circuit configuration including a self-commutating rectifier (2) in parallel with the a.c. voltage terminals of the main static power rectifier. The self-commutating rectifier (2) is modulated with d.c. voltage (giving a reactive power rectifier) and connected across the main rectifier a.c. voltage terminals in order to compensate the reactive (wattless) power. The polarity of the common a.c. input voltage is then determined by the reactive power rectifier bridge (2) and functions as the commutation voltage for the main rectifier's thyristors (T1-T4). ADVANTAGE - Optimum power factor in feeding d.c. intermediate circuit (d.c. link reactor) from a.c. voltage mains.

Title: Coin insertion device
Inventor: CERRET CLAUDE
IPC: G07F1/04
Filed: 1988-03-02
Abstract: A coin insertion device for automatic service machines has a lock (1) for a coin (6). A slide (4) can assume a working position or a rest position (R). In the rest position (R), the slide (4) exposes an insertion slot (5) and simultaneously closes the lock (1) with respect to a money duct (10) by means of a bottom (8). In the working position, a plate (7) prevents foreign bodies penetrating the automatic machine as it covers the insertion slot (5). Simultaneously, the lock (1) is emptied towards the money duct (10) by means of a slot. If a coin (6) is inserted into the automatic machine and the presence of the coin (6) is detected by a detector (12), the slide (4) is moved into the working position. The inserted coin (6) falls into the money duct (10). As soon as the coin (6) is recognised in the money duct (10), the slide (4) returns into the rest position (R). Foreign bodies are removed by means of an expeller (3). <IMAGE>
Patent DE-3809139-A1 (DE)
Inventor: BALTZ MICHAEL
IPC: C23C14/06
Filed: 1988-03-18
Abstract: An interlayer between a metallic substrate material of little or no corrosion resistance and a coating applied by the PVD process comprises palladium-nickel alloy containing 30-90 wt.% preferably 60-85 wt.% of palladium deposited from an aqueous electrolyte containing palladium and nickel ammines at a palladium concentration in thge range 2-20 g/l and a nickel concentration in the range 5-30 g/l, together with optional conductivity salts and organic additives which can contain sulphur, wherein the electrolyte components are selected so that any sulphur precipitated with the alloy has a valency exceeding two. The presence of the Pd-Ni alloy improves the corrosion reisitance and mechanical tenacity of PVD coatings in finishes where the substrate has little or no corrosion resistance, by avoiding a single PVD layer which would commonly be in the thickness range of .3-1 micron, and the coating defects of porosity characteristic therewith. The coating applied by PVD may be a boride, carbide, nitride, oxide or a silicide of elements in subgroups 4 to 6 of the periodic system, eg TiN, TiC optionally containing aluminium, cobalt, gold, carbon, copper, nickel, palladium, titanium, zirconium or tantalum. The substrate may be aluminium, lead, copper, magnesium, nickel, silver, steel, zinc or an alloy material based thereon which may further by provided with a layer of copper, copper alloy, nickel, nickel alloy, silver or tin alloy. The metallic substrate may itself be an electroplate coating on a galvanisable material such as coatings of copper, copper alloy, nickel, nickel alloy, silver or tin alloy.
