Title: Composite material for prefabricated house wall finish - provides movable rear ventilating air layer, with support layer with thin cross arms
Inventor: GUELDENPFENNIG ROLF DIPL CHEM
IPC: E04F13/04
Filed: 1976-10-28
Abstract: The composite material has a fissure-bridging effect, and is suitable for imparting a weatherproofing, jointless, noise-insulating, impact-absorbent, and fire-retarding quality to interior and more esp. exterior coating on light-weight or solid walls. A dormant, but freely movable, layer of air is retained between the weatherproof external coating and the base. The external layer is linked to the base by a dimensionally stable, rot-resistant support substance with thin, but freely movable, cross arm pieces. The support material may be made from synthetic organic polymer fibres, esp. polypropylene fibres, pref. bound to cross arm with synthetic latex or similar adhesive. Used esp. in prefabricated wooden housing, this provides all-round protection, and can be applied in a single process.

Title: Liq. movement reversing system in soil strata - uses compressed air injected into soil for bringing liquid to surface
Inventor: STOLPE HARRO
IPC: E02D31/00
Filed: 1976-12-22
Abstract: This arrangement can also be used for replacing previously applied or similar precautions or supplement them. The arrangement can be used for reclaiming ground damaged by oil spillage. Alternatively, it can be used in agriculture to prevent high concentrations of fertilizer or pesticides used in intensive farming from reaching the ground water region. A fluid agent is injected under pressure into the existing or expected movement path of the liquid. This pressure acts in the opposite direction to the movement path or the existing potential difference. The fluid agent is introduced continuously into the ground or rocky strata. Air can be used as the fluid agent and is pumped into the ground through lances. The pressure is distributed in the ground to interfere with the liquid flow and the liquid is forced on surface.

Title: Liquid metal cooled reactor fuel element leak-tested - by wet sipping with continued coolant flow through element
Inventor: FLECK CARL M DR
IPC: G21C17/025
Filed: 1977-01-19
Abstract: Fuel elements are tested which are used for liq. metal-cooled, esp. Na cooled reactors; a vertical tubular shaft is mounted and sealed to the top of the fuel elements, the liq. coolant metal inside the fuel element ascends into this shaft and a noble gas is bubbled into the liq. metal in the shaft and then conducted to a detector which indicates the presence of any fission prods. A controllable flow of the liq. coolant metal is maintained inside the shaft, at least temporarily. For the "wet sipping" of fuel elements in the reactor core. By maintaining a controllable flow of liq. metal coolant inside the shaft itself it is possible, firstly to limit the rise of temp. of the fuel element thus reducing risk of damage and, secondly, to minimise or eliminate thermal shock when the heated fuel element is returned to normal reactor operating temp. by reinstating the full flow of coolant to the element.

Title: Cine camera exposure control system - uses exposure meter which has alternative settings for stills and cine exposures
Inventor: NIEDERHAUSER MARC
IPC: G03B7/085
Filed: 1977-04-05
Abstract: A cinematograph camera fitted with an exposure meter has facilities for determining the optimum aperture setting. The exposure meter (11, 12) has provision for measuring both steady and alternating light, the alternating light being derived from the intermittently operating film transport mechanism (4, 7, 8) operating an intermittent shutter. A circuit (9, T1) controlled by the mode of operation of the camera activates the direct light measurement alternative for still exposures and the interrupted light measurement is in operation in cinematographic exposures. The alternating beam may be generated by a reflecting revolving shutter (4) reflecting light intermittently to the photosensitive element (11).

Title: Adjustable hinge for furniture components - has longitudinal and vertical adjustment using guide profile with flexible key
Inventor: GAUGG JOHANN
IPC: E05D5/02
Filed: 1977-05-04
Abstract: The hinge has two pivoted hinge parts for fastening. One of these is held, for example, on a furniture door and other part is fastened on a mounting block on the furniture frame. The hinge arm can be adjusted longitudinally relative to the mounting block into required position. The fixing of hinge is simplified because the hinge arm can be also moved vertically up and down at right angles to longitudinal direction. The hinge arm (6) with the mounting block (1) has matching key profiles ensuring flexibility across the longitudinal direction of the hinge arm or mouting block. These spring keys (10) project into grooves (3,9) so that they can be moved. The mounting block hence acts as a guide rail for hinge arm.

Title: Burner for crushed raw powder - has closed furnace chamber through which gas current flows under negative pressure
Inventor: BORNER RAOUL
IPC: C04B2/10
Filed: 1978-03-22
Abstract: Assembly for burning crushed raw powder to acidify, sinter or melt mineral in the powder comprises a closed furnace chamber through which a current of gas flows from one end to the other under negative pressure. The raw powder is introduced into the furnace chamber from a silo and burnt in a combustion zone to form a burnt reaction prod. which is sepd. from the current of gas under negative pressure. Because of the negative pressure pptn. of the CO2 takes place quickly and requires less heat for calcination. The direct impact of heat on the solids in the gas current prevents the formation of a burnt skin and speeds up the reaction.

Title: Membrane filter for microorganisms - with cellulose nitrate filter membrane supported by bosses between flat trays
Inventor: ALHAEUSER ERICH
IPC: B01D46/54
Filed: 1978-05-10
Abstract: A membrane filter, esp. for the sepn. of microorganisms from liquids such as fully desalinated water in combination with ion exchange systems, holds the filter membrane between two flat trays. The membrane is supported across its surface by a grid of projecting bosses which face each other on the inside of the flat trays. Trays and bosses are pref. made of plastics. The relatively larger free passage area of this filter results in a smaller and more compact design. The components can be replaced at low cost.

Title: Aerosol and foam generator - with radial blowing agent jets diverted into annular gap with entrained material
Inventor: BISA KARL DR
IPC: B05B7/08
Filed: 1978-05-27
Abstract: A device to produce aerosol or foam consists of an outer tulip-shaped baffle which acts as a deflector for the blowing agent. It forms in combination with a central headpiece an annular slot through which the blowing agent and the atomised material entrained by it must pass. The ratio of entrained liquid or powder to the amount of blowing agent is much increased thereby. The spectrum of the particle size in an aerosol or a bubble size in a foam is narrowed. Materials which are sensitive to shear forces (microoroganism suspensions) are not detrimentally affected.

Title: Barrier layer FET - mfd. by under etching bottom mask layer to cover barrier layer surface
Inventor: KOHN ERHARD DIPL ING DR
IPC: H01L29/812
Filed: 1978-06-01
Abstract: A barrier layer FFT is produced by using a mask over the channel to impart a high impurity concentration to the source and drain regions. The bottom mask layer is underetched until it covers only the surface of the intended barrier layer and the source and drain contacts are applied. The top mask layer is removed and the bottom layer replaced by a mask representing a negative image (window) of the latter in which the barrier layer is deposited. The distance between source/drain and gate contacts can thereby be minimised and extremely low contact resistance between channel area and source/drain contacts can be achieved.
