Patent DE-2604399-A1 (DE)
Title: Sheet steel and concrete composite ceiling - has anchoring bars through holes in sheet sloping double stems
Inventor: MUESS HANS ING GRAD
IPC: E04B5/40
Filed: 1976-02-05
Abstract: In storeyed buildings of steel or reinforced concrete construction, the end anchorage for shaped sheet steel plate composite ceilings is independent of the substructure, and is used for laminar adhesion between steel sheet and concrete above a support. For this purpose anchoring irons, in the form of round steel bars of any shape, are led through holes (3) in the sloping double cross arm stems of steel sheets (1), one behind another, in numbers dependent on structural demands, before concreting. The steel sheets are effectively anchored in the concrete (2) independently of the substructure. The holes may be drilled after laying the sheets and before concreting, or mechanically, electrically or hydraulically pressed in by pointed punches made of a harder material.

Title: Treating effluents contg. fats, polysaccharide(s) and/or protein(s) - to improve their sedimentation rate and filterability by adding specific enzymes to cause degradation
Inventor: CARLSSON CARL-GOERAN HERBERT
IPC: C02F3/34
Filed: 1976-07-26
Abstract: The filterability and tendency to settle of slurries of fats, polysaccharides and/or proteins. is increased by adding to the slurry and enzyme which strongly degrades the macromolecular substance(s) present. The enzyme used depends on the effluent's content (e.g. lipases for fats, amylases and/or celluloses for polysaccharide and proteinases for proteins). The addn. of 0.001-5 wt.% pref. 0.1-1 wt.%, (based on dry wt.) gives marked improvement. Biological treatment is at 5-70 degrees C, pref. 20-60 degrees C. Used in the treatment of effluent from the paper and foodstuff industries as well as in treating household refuse. The method is cheap and rapid.

Patent DE-2641177-A1 (DE)
Title: Antivibration lock for threaded fastener - has raised teeth on underside of bolt head or clamping face of nut
Inventor: RIEBLING WOLF DIPL ING
IPC: F16B39/282
Filed: 1976-09-13
Abstract: To secure screw heads and nuts against unwanted unscrewing due to vibration, a number of raised teeth (5) are provided in the axial contact areas (4). The teeth, which are located all around the bolt shaft (1) on the bolt head and around the screw hole of the nut, are formed out from the solid material. When the screw bolt or nut is installed, the teeth dig into the material they come in contact with, thus securing it against unscrewing due to greatly increased friction resistance against torque.
Patent DE-2643191-A1 (DE)
Title: Commutator for electrical machine - has skewed laminations to provide smoother commutation and mechanical running
Inventor: KUHLOW JUERGEN DIPL ING
IPC: H02K13/10
Filed: 1976-09-22
Abstract: The laminations (2) of the commutator (1) are skewed relative to the rotational axis (3), the laminations remaining parallel to each other. This skewing, which is typically two commutator bar pitches, ensures that the current flow between the segment leaving the brush and the brush trailing edge is not suddenly interrupted but broken gradually. This has the effect to reducing leaving edge sparking at the brushes. It may also have beneficial effects mechanically. If there is unevenness between laminations, or if the insulation between bars is not even the brushes do not rise or drop so abruptly and thus quieter and less damaging running follows.
Patent DE-2647284-A1 (DE)
Title: Magnetic record disc for density records - consists of tape-wound pancake disc giving automatic mechanical tracking of reading head
Inventor: IRMLER RUDOLF
IPC: G11B5/74
Filed: 1976-10-20
Abstract: A disc record is used for magnetically recorded signals. It gives a high ratio of storage surface to total surface. It permits high storage density while using the normal arrangement to guide the recording and reading heads. The recording element is in the form of a tape (4) with a magnetic coating, wound together with a narrower spacer tape (6) around a central core to form a flat disc (3) which may be supported on a metal disc for stability. The tape is flexible, and yields to the passage of the recording/reproducing head (5) by bending aside to allow reading of the face of the strip (7). This action also serves to give mechanical guidance to the head to assure tracking.

Title: Filtration plant for sepg. oil particles from effluents - has plates of reconstituted synthetic foam with broken cell walls (SW 19.12.77)
Inventor: ABRAHAMSSON TAGE
IPC: B01D39/16
Filed: 1977-10-22
Abstract: Oil particles are sepd. out of effluents by a filter arrangement comprising a housing with inlet and outlet between which a self-supporting body forms the filter element. The filter element consists of small pieces of a soft, foamed, synthetic material, with open cells. The cell walls are broken down by subjecting the material to a mechanical, non-disintegration pressing action. The small pieces of foam are afterwards bonded together by a adhesive under pressure. Fully effective means of sepg. oil from effluents is provided much more efficiently than by scattering absorbent material on the surface of the water on floors, etc. which in any case is impractical with, e.g. the swilling water from ships oil tanks. The filter(s) bind the oil particles which expel the water from the filter material so that the filter becomes practically satd. with oil without allowing any to pass through.

Title: Caged ball bearing for linear and rotating shaft - has transfer zone in outer track with elastic deflection pad at turning point
Inventor: HOFFMANN ALFRED DIPL ING
IPC: F16C29/06
Filed: 1978-04-04
Abstract: The ball bearing permits axial movement of a rotating shaft and comprises a cage with a series of oval guide tracks for the ball bearings and an outer casing with cylindrical tracks parallel to the shaft axis. At each end, transfer sections are at a greater radial distance from the axis than the parallel sections. These transfer sections permit the balls to pass from one axial guide path to the other whilst following the cylindrical contour of the shaft. In order to reduce the frictional stress on the balls and the tracks in the transfer zone, the outer casing has an elastic weak point which permits some deflection of the balls from their path. The weak point is in the form of a cross-sectional reduction, pref. a slot or groove in the outer surface of the outer casing extending over the entire width of the transfer zone. The bearing permits linear movement of a rotating shaft whilst guaranteeing an even loading of the bearings and a reduction of frictional stress. The life of the bearings is consequently extended.

Abstract: Hydroisomerisation of specified gasoline fraction is carried out a 320-400 degrees C and 20-60 atm. with a space velocity of 1.0-1.5 hr-1 using a catalyst comprising an amorphous Ni aluminosilicate and a NiCaHY zeolite in a wt. ratio of 60-90:40-10. The catalyst contains 7-10 wt.% Ni, 5-6 wt.% Al2O3, 80-86 wt.% SiO2, 1-2 wt.% Ca and 1-2 wt.% H. Specifically, the feed is a straight-run gasoline fraction boiling in the 85-160 degrees C or 160-195 degrees C range or a coker gasoline fraction boiling in the 35-85 degrees C or 43-170 degrees C range (N.B., the used of 35-85 degrees C coker gasoline is not claimed). The process gives high-octane products (MON clear 87-90) useful as motor fuel blending stocks, from low-octane feeds under mild conditions. The catalyst has high activity and stability.
