Patent DE-2713553-A1 (DE)
Title: Light weight cable for heavy pulse currents - consists of insulated seamless conducting tubes arranged around central support wire
Inventor: VORREITER LEOPOLD DR
IPC: H01B7/00
Filed: 1977-03-28
Abstract: Equipment is used for gathering electrical energy from the atmosphere and from lightning strokes. The cable forming the conductor between the gathering point, for example a balloon, and the ground should be as light as possible to limit the weight which the balloon has to lift. A satisfactory cable can be constructed by substituting tubes for the normally solid wires forming the conductor. Seamless tubes are employed which are either drawn or rolled. These tubes are coated both internally and externally with an insulating varnish. The tube material is pref. a light metal e.g. aluminium or magnesium. Support and tensile strength is provided by a solid core consisting of a steel or copper wire around which the tubes are arranged. In comparison with a solid stranded cable of the same dimensions a tubular one can have 75% more conducting area and 56% less mass.

Title: Two stage high pressure compressor - has stepped free piston with spring assisted linear electric motor drive
Inventor: BARTHALON MAURICE
IPC: F04B7/04
Filed: 1977-04-04
Abstract: The compressor provides high pressure delivery of fluid for refrigeration and similar uses. It comprises a piston, freely operating in a cylinder and powered by a linear electric motor on end. This is spring assisted and, if required, two linear motors can be used one at each end and operating alternately. The piston is stepped, providing two stage compression. The larger dia. section (8a) takes the fluid and delivered this under low pressure to the smaller diameter piston (8), for discharge as high pressure fluid. Spring loaded disc valves (9, 13, 14) are used and the fluid on the low pressure side forms a cushion (5) to absorb stresses.

Patent DE-2751956-A1 (DE)
Inventor: LAROCHE RENE-VICTOR
IPC: G05D21/00
Filed: 1977-11-21
Abstract: In an open chamber (1), in particular intended for the continuous surface treatment of aluminium cans, which chamber has a treatment and evaporation part, a liquid (7), composed of the two poorly miscible components water and for example perchloroethylene, is evaporated and the composition of the vapour mixture is controlled by addition of water in relation to the vapour temperature measured in such a way that the steam content is always less than that of the azeotropic vapour mixture and is preferably 2 to 2.2 % by weight, which corresponds to a vapour temperature of about 112 DEG C. For this purpose, the vapour mixture is condensed at the outlet of the chamber (1), fed to a water separator (14) and the condensate water is collected in an intermediate store (16) from which it is returned in portions into the liquid (7) via a metering device (18). As a function of the temperature measured in the chamber (1) and of the likewise measured level of the condensate water in the intermediate store (16), fresh water treated with an additionally added ammonia solution is added in portions to make up the water losses. The condensed perchloroethylene constantly flows back into the liquid (7), which, moreover, is supplemented by fresh perchloroethylene. <IMAGE>

Title: Preserved image electrostatic copier - uses control grid and cleaner cut=off to preserve latent image on drum for up to 200 good quality copies
Inventor: SUZUKI YOSHIRO
IPC: G03G15/16
Filed: 1978-03-02
Abstract: An electrostatic copier of the drum transfer type is such that the electrostatic latent image is not destroyed., by choice, so that several prints may be made from it at high speed and of high quality. The latent image on the drum surface passes through a magnetic brush developer so that a picture is formed on the drum surface which can be transferred to the copy material. Between the conducting rollers there is an electrically conducting grid mesh situated between drum and corona discharge electrode. Controlling the potential applied to this grid and the conducting rollers from two potential sources determines whether the copier produces single or up to 200 good quality copies and whether the latent image cleaning brush and electrode removes the image ready for another exposure.

Title: Reciprocating internal combustion engine - has gases transferred between cylinders of different sizes to increase effective compression ratio
Inventor: HUEBNER HANS-JUERGEN ING GRAD
IPC: F02B41/06
Filed: 1978-03-20
Abstract: The engine has pistons reciprocating in cylinders of two different sizes within a common cylinder block. The cranks of the smaller dia. pistons are displaced by 180 degrees from those of the larger ones. Air is initially compressed in a large dia. cylinder and then transferred to a small dia. cylinder for further compression and combustion. After initial expansion in the smaller cylinder the gases are transferred to a different large dia. cylinder for a further stage of expansion. The transfer passages are short and thermally insulated. The timing and transfer system enable a higher overall compression ratio and therefore efficiency to be obtained.

Title: Sterilisation chamber lid closure - by hand-wheel turning wedging levers between flanged recess and lid
Inventor: HERZ HELMUT DIPL ING
IPC: F16J13/24
Filed: 1978-04-13
Abstract: A pressurised treatment chamber esp. for sterilisation plant, is closed by a lid which is pressed against a sealing strip around the chamber opening. Several thrust levers are wedged between the recess of a flange and the outside rim of the lid. The pressure to the levers is applied by a handwheel which can be screwed up on a central boss of the lid and moves the inside ends of the thrust levers in ball joints attached to the outer race of a double-row self-aligning ball bearing. This ensures that all areas of the lid periphery are pressed with the same force against the seal ring and that only little force is needed to tighten the lid.
