Title: Multistage roll stamping machine for continuous metal strip - where pairs of rolls are fitted with mating punches and dies, and are used instead of transfer press
Inventor: WEIHMAYR JUN JOSEF ING GRAD
IPC: B21D28/36
Filed: 1979-01-05
Abstract: The strip travels through a row of pairs of rolls producing profiled strip and/or stamping holes in the strip; and the last pair of rolls is driven at a higher speed than the preceding pairs of rolls in order to compensate for the stretching of the strip which occurs during the forming and stamping operations. The stamping rolls pref. contain circular rows of holes in their periphery in which stamping punches with radial axes are located. Each stamping roll is used with a roll contg. holes corresp. with the punches and also fitted with ejector pins so the strip does not adhere to the rolls. This machine replaces a press or a transfer press; it can be operated at higher speeds than presses, and requires neither feeder nor straightening units; and it creates less noise than a press.
Patent DE-2900966-A1 (DE)
Title: Mineral e.g. uranium extraction from liquid body e.g. sea - by passing flow through flexible sheet of permeable adsorbing material
Inventor: LESSER RICHARD DIPL CHEM DR RE
IPC: B01D15/00
Filed: 1979-01-11
Abstract: Mineral (e.g. uranium) is extracted from a liquid (e.g. sea) by passing flow through a bed comprising thin flexible sheets of permeable adsorbing material. A sheet may be held with its surface horizontal or moved relative to the sea by an attached line which may be secured to a buoy. The line may pass through the sheet to an anchor on the sea-bed allowing the sheet to sink under its own weight. Retrieval of a sheet is achieved by attaching to it a line from a boat or other object, (possibly the same line) at the central region of the sheet, in such a way that the operation first produces an umbrella-style folding of the sheet. Using a titanium hydroxide adsorber, the method is partially suited to the extraction of uranium from the sea as carbonate. Assuming a uranium concentration of 3 mg/m3, and a sheet radius of 56 m, a single sinking to 1000m depth could produce a maximum yield of 30 Kg of uranium.

Title: Distribution bus=bar system contained in channel section carrier - with movable adaptors for power supply and load connection and with plate used to screen adaptor prior to full insertion
Inventor: NAWRATH PETER
IPC: H01R25/14
Filed: 1979-03-06
Abstract: The versatility of a distribution busbar system can be increased if the point of power input to the busbar is as readily movable as the tapping positions for power outlets. To enable this specific safety rules have to be observed in order to protect users. The input adaptor has terminals which are screened against contact until the unit is fully inserted into the busbar trunking. To achieve this, the adaptor has a base and a movable plate. With the adaptor free, the plate moves such that the live contacts are screened. Inserting the adaptor into the trunking and turning the plate gives rise to a mechanical interaction with lands in the trunking. The adaptor can then be pushed fully home, the contacts released, and connection made to the live bus rails.

Title: Three=dimensional carpet sections, etc. for vehicle interiors - formed simultaneously with curing of pile-securing adhesive backing
Inventor: VERMEULEN JOHANNES
IPC: D06N3/14
Filed: 1980-11-25
Abstract: Sections of, e.g., tufted carpet material having a three-dimensional form for cladding vehicle interiors, etc. are produced by coating the underside of the material with a binding layer of polyurethane and heating it to 80 deg. C. Whilst the material is still warm, and before the polycuts out sections polyurethane has cured, the material is passed through a cutting machine which cuts out sections of the required shape, and then through a press which imparts the required three-dimensional form, in which condition the polyurethane is allowed to set. Alternatively, the sections may be cut out and formed before being coated with polyurethane. The forming operation is concurrent with the curing of the polyir polyurethane, instead of a separate process requiring re-heating of the material, giving economies in time and power consumption.

Patent DE-3100318-A1 (DE)
Title: Measuring wheel
IPC: G01B3/12
Filed: 1981-01-08
Abstract: The measuring wheel can be used for accurately measuring distances on maps. Walkers frequently use pedometers in order to determine the distance travelled by them. However, this method is quite inaccurate. Since walkers almost always have a map of trails which they follow, they can use the measuring wheel to determine the accurate length of the path afterwards or even in advance. Similarly, the measuring wheel can be used by motorists. It can also be used in geometry. The special feature of the measuring wheel is the adjustability of the scale as a result of which it can be used in many ways. In principle, the measuring wheel can also be manufactured with a mechanical counting mechanism but due to the advance in digital counting mechanisms, it is advisable to use these.

Title: Pressure vessel for storing and transporting gases and gas mixtures at high pressure and method of producing it
Inventor: WAGNER ALFRED
IPC: F17C1/14
Filed: 1981-02-04
Abstract: Pressure vessels for storing and transporting gases and gas mixtures at high pressure having a tubular metal body, said pressure vessels being formed into a dome-shaped end cap at least at one end, are to be produced for any types of gas in any state of aggregation at a high internal pressure of about 200 bar and over in such a manner that they have as low a weight as possible and consequently result, all in all, in a higher working load. It should also be possible to manufacture them cheaply. This is achieved by a pressure vessel in which the wall thickness of the tubular section of the aluminium or aluminium-alloy body is reduced compared with the wall thickness of the dome-shaped cap(s) and is surrounded by a jacket of fibre-reinforced, in particular glass-, carbon-, aramid- or boron-fibre-reinforced plastic. The fibres of the jacket should be wound around the aluminium body and produce, at least partially, helical lines on the latter. <IMAGE>
