Patent DE-2653942-A1 (DE)
Title: High pressure fuel injection pump - has regulator rack expansion rate calculated to compensate for fuel viscosity difference
Inventor: HEBERLE HANSJOERG DIPL ING
IPC: F02M59/44
Filed: 1976-11-27
Abstract: The fuel pump regulator rack metal is selected for its linear expansion properties in comparison with the pump housing expansion to provide an increased fuel injection volume to compensate for volume loss due to decreased fuel viscosity when the fuel temp. rises. This provides simplified pump exchange. The fuel temp. increases by about 3 deg.C on leaving from pump to pump and its viscosity drops 0.25% each time. The same delivery volume of each pump gives an injection difference of 0.25% between two cylinders.

Title: Malt kiln drying floor spreading system - has feed screw discharging into travelling hopper with distributor screw underneath
Inventor: METZGER HERMANN
IPC: F26B25/00
Filed: 1976-12-03
Abstract: A malt kiln has the green malt spread over a floor by means of a spreader which is supported on a wheeled carriage travelling on rails supported above the floor. The carriage supports a funnel which allows the malt to fall onto a distributor screw below, at right angles to the rails. This funnel is fed in turn by a delivery screw inside a housing at right angles to the lower screw. As the funnel travels along, it opens in turn a set of flaps under the housing. In another design, the upper screw is divided in two parts connected by a hinge so that it can swing about an end pivot to discharge continuously into the funnel without using the flap system.

Title: Rhodium sepn. from iridium and or ruthenium - by extraction of iridium and ruthenium from acid soln. into solvent contg. quat. ammonium salt
Inventor: BALTZ JOHN
IPC: C22B3/28
Filed: 1977-01-17
Abstract: Process consists of treating the aq. soln. with an H2O-immiscible organic solvent contg. a cpd. of formula R1R2R3R4N+ where R1-R4 are opt. branched alkyl or aromatic hydrocarbon (I) (sufficiently sol. to give a 1% soln.). The contact is effected at emf-500 to -1000 mV, then the org. extract (A) (contg. Ir and R1) is sepd. from the aq. phase (B) (contg. Rh) and treated with is not the stoichiometric amt. of an aq. alkali stripping agent (ASA) required for neutralising the organic phase. The treatment affords an aq. phase loaded with Ir and Ru (as ppts. of alkaline salts), and a stripped organic phase, and both phases are then treated with a soln. of an acidified reducing agent (RA) ( is not  the stoichiometric amt. ASA) to redissolve the Ir and Ru ppts.). Highly selective economical process rapidly and easily separates Rh from Ir and Ru in aq. mineral acid solns. Process is partic. suitable for operations on a continuous basis. Prefd. (I) have at least one of R1-R4 = fatty alkyl. Initial extraction is pref. effected at 20-40 degrees esp. 25 degrees and at -900 mv (maintained e.g. by addn. of NACL).

Title: Scraper conveyor with chains sliding in troughs - has lower bar edges clear of trough bottom to reduce noise generation
IPC: B65G19/24
Filed: 1977-04-12
Abstract: The scraper conveyor has one or more chains sliding over the bottom of a trough, with bars fixed to it to push the material before them. To reduce noise, the bars (21) are so shaped or mounted on the chain links that their lower edges are slightly clear of the trough bottom (18) or of cladding material (43) covering it. One or more of the bars may be so shaped or mounted that the lower edge (22) does scrape over the bottom. The bars can be of flat steel, their lower edges being set back below the side of the chain links, while their upper ones are flush with the top side. On the return run, only the chain itself can be arranged to run along a guide rail (42) below, the bars being clear of the housing on all sides.
Patent DE-2717901-A1 (DE)
Inventor: ARNSTEINER ANTON
IPC: A63C5/04
Filed: 1977-04-22
Abstract: The intention pursued by this climbing aid for cross-country skiing is the maintaining of a high degree of slip with optimum adhesion under downward pressure, and adequate lateral stability. To this end, a profiled section is provided with a step-like formation which has a section (5) dropping in a wedge-shaped manner and a section (6), immediately adjacent thereto, which is parallel to the running sole of the ski. The formations are approximately equally spaced. These formations are defined by an edge of arcuate shape which is formed in the manner of a corrugated line (7) and in each case extends at an acute angle towards the edge of the ski. <IMAGE>

Title: Double filter with automatic cleansing for dishwashers - has finer filter swivel mounted for thorough or surface flushing
Inventor: SCHAEFER ERHARD
IPC: A47L15/42
Filed: 1977-06-27
Abstract: In the dishwasher there is a fine filter (7) at the bottom of the wash container (1) connected into the circulating system. A coarse mesh filter (6) which covers the fine mesh filter is connected into the drainage system. The fine filter can rotate about a horizontal axis from the filter position into a position which alters the flow conditions at or in the fine filter. The fine filter can thus either be brought into a steep flow position leading to the drainage system which allows a good cleaning of the surface through the water flow or it can be turned into a position in which the pumped-out soap solution passes right through so that after pumping it can be moved back practically free of residue into its original position. This means that even with few intermediate rinsing processes the danger of smearing through dirt particles in the fine filter is considerably reduced if not completely ruled out.

Title: Fluid atomiser suitable for engine fuel supply - has flow channel for fluid jet, and sonic beam at right angles to flow
Inventor: PROELSS HANS DIPL ING
IPC: B05B17/06
Filed: 1977-09-17
Abstract: The atomization process for fluid jects or drops, using a sound generator and converter, is suitable for the fuel supply for an engine. The fluid jets (4) are moved through a flow channel (2). The generator (6) and/or converter produce a level relatively thin sound field for level expansion, which extends almost at right angles to the flow channel. The sound converter is positioned in the flow channel, so that the majority of the particles to be atomized strike it. The converter is excited with a frequency so as to oscillate at such an amplitude that the particles are atomized. The fluid jets/drops flow through a gas, or are moved by it.

Title: High yield hydrolysis of acrylonitrile to acrylamide - using a catalyst obtd. by cooling volatilised copper and organic solvent
Inventor: MARTON MICHAEL
IPC: B01J37/02
Filed: 1978-01-16
Abstract: A finely divided metallic Cu catalyst obtd. by volatilising Cu, cooling the vapour in contact with an organic solvent and heating to ambient temp. is used for the prodn. of acrylamide from acrylonitrile and water. In an example acrylonitrile is reacted with water at 120 degrees C under nitrogen (up to 70 psi) for 6 hrs. using a catalyst obtd. by vaporising Cu on a liq. N2 temp. controlled wall on which THF is also condensed, heating the prod. to room temp. and removing the THF in vacuo. Conversion to acrylamide = 40%. Acrylamide is a flocculent, paper strengthening agent and additive for tert. oil recovery. Improved yields of acrylamide are obtd. without the attendant worry of disposal of unwanted side prods. or undesirable separation steps. The catalyst is not rapidly poisoned by polyacrylamide formation.

Title: Low pressure casting of light metal and alloys etc. - using furnace with separate melting and holding zones
Inventor: BUESCHER ULRICH
IPC: B22D18/04
Filed: 1978-02-10
Abstract: The raw material is fed into a furnace zone (a) held at a much higher temp. than the m.pt. of the material, whereas the molten material is held in a separate furnace zone (b) at a lower temp. suitable for casting.
