Patent DE-2403085-A1 (DE)
Title: Bottle washing plant label remover - bottles carried between sprays by belts having different speeds, causing rotation
Inventor: OBMANN GEORG
IPC: B08B9/08
Filed: 1974-01-23
Abstract: A bottle washing installation includes a label removal section where the bottles are carried by belts between tangential sprays, the bottles supported by the edges of two different belts with a gap between. One belt of each pair travels at a speed different from the other, thus rotating the bottles as they travel on. The sprays are directed tangentially in opposite directions, directed to assist the rotation, and the spray boxes are raised and lowered during the movement. spray slots may be used as well as spray holes, and chemical additives can be included in the water supply to assist removal. The speed of the belts can be altered independently.

Title: Etching semiconductor slices before doping - with mixt. of metaperiodic and hydrofluoric acids
Inventor: HUSZKA ZOLTAN DIPL ING
IPC: H01L21/306
Filed: 1974-02-06
Abstract: In addn. to surface treatment with or without degreasants, wetting agents, acids, alkalis, organic solvents, or water, the semiconductors are immersed for 5 seconds to 5 minutes in a soln. contg. 25-1000g HIO4, 25-200ml HF and 1 litre H2O, followed by rinsing and drying. The treated substrate is then subjected to mfg. operations consisting of heat- or vacuum-treatments. The substrate can be an element of gp. IV or a cpd. of elements in gp. III or V. After the above etching and before mfg. operations, the substrate may be heated 10-120 minutes in vacuum, H2, or inert gas at 100-800 degrees C. The substrates are atomically clean and the iodine layer is easily removed. The layer of iodine produced in this process protects the substrate from oxidn. until the next stage of mfg. is undertaken.

Title: Anchored buoy with keeling compensation - has flat buoyancy section of half the complete buoy displacement volume
Inventor: ROHDE JOACHIM DR RER NAT
IPC: B63B22/18
Filed: 1974-05-07
Abstract: The buoyancy section of the buoy, has a displacement vol. of about half the complete buoy displacement vol. The section is flat, so that the complete normal depth of immersion of the buoy, is not larger than the approx. value of its largest horizontal dia. which coincides roughly with the cross sectional diameter at the normal water line. The displacement section of the buoy is completely below the water line, rigidly connected to the buoyancy section, and consists of long bodies with horizontal longitudinal axis, positioned sidewards from its centre of gravity. A corresponding high position of the total centre of gravity causes the static bias return momentum during keeling-over to be only as large, as is necessary due to the wind- and flow resistance.

Title: Tailgate hoist with rear crash bar - is hinged on linkage to pull into position on struts
Inventor: FRITZ MATHIAS
IPC: B60P1/44
Filed: 1974-05-31
Abstract: The rear of the lorry is fitted with a tailgate operated by two sets of hydraulic rams. Special support arms (15) are hinged on the linkage support and are suspended from the upper linkage by chains. When the tailgate is raised for transport the support arms are pulled up. A crash bar is raised for transport the support arms are pulled up. A crash bar is attached across the ends of the support arms, extending across the width of the lorry, and this is pulled up against special stops (18) at the ends of rigid arms (26) under rear of the lorry. When the tailgate is dropped the crash bar drops to the ground. For normall road use the crash bar prevents cars from running under the rear of the lorry, while its hinged design does not impede the operation of the tailgate lift.

Title: Slit strip edge trimmer - has cutter between guide rollers to deburr and descale coated surface before longitudinal seam welding
Inventor: REUTHER FRANZ-JOSEF
IPC: B23D1/26
Filed: 1974-12-05
Abstract: The coated slitted strip is profiled and seam welded. For a satisfactory longitudinal weld the strip edges are deburred and descaled before forming, with min. metal removal and reduced cutter wear. A raised slitting burr is flattened outwards, then removed by descaling. A cutter between the guiding rollers finishes the edge square at constant strip width. Rollers flatten the continuously fed strip burred edges. An adjustably angled descaler removes the deformed burring. V grooved rollers guide the strip edge whilst cutter finishes the edge. Symmetrical guides and cutters trim both edges, with screw adjustment for strip width.

Title: Exposure meter for SLR camera - measuring at top and bottom of image without increasing pentaprism exit surface area
Inventor: OKUNO YOUICHI
IPC: G03B7/099
Filed: 1975-05-30
Abstract: Exposure meter comprises a measuring element (11) which measures the light beam portion leaving the upper section of the exit surface (8) of a pentaprism which forms part of the finder, after this light beam portion has been reflected by the two sloping roof surfaces (5, 6) and the front surfaces (7) of the pentaprism. An optical device (9) comprising a transparent body with a refractive index at least equal to that of the pentaprism has one surface in contact with part of the exit surface, so that the light beam portion, which after reflection by the two roof surfaces, the front surface, and the roof surfaces again, is the object of total reflection by the exit surface portion, leaves the exist surface. The light beam portion is then measured via the optical device by a second measuring element (12).

Title: Motor cycle disc brake assembly - has permanent magnets inside pistons for retention of brake pads
Inventor: ROHRBACH WALTER
IPC: F16D65/14
Filed: 1975-07-26
Abstract: The disc brake assembly for a motor cycle includes two brakes pads (14) and a brake disc (12). When the wheel together with the brake disc (12) is removed, the brake pads (14) tend to fall away from the brake pistons (6). To avoid this permanent magnets are placed inside the pistons (6) so that they keep the brake pads (14) in position. This is possible because the friction pads (14) are mounted onto ferro-magnetic backing plates (15) such as steel. A radial lug on the backing plate which fits into a location slot on the body (2, 3) secures the brake pad assembly against rotation.
