IPC: A47L15/48
Filed: 1976-12-08
Abstract: The machine (1) has two input dorrs (2,2') and two sides, one (A) for dirty articles, and the other (B) for purified articles, thereby separating clean from bacteria-laden items. The cleaning compartment (4) is connected by a ventilation pipe (5) with the external atmosphere; and the dirty side (A), and incorporates a microbe filter (). The ventilation pipe (5) opens out into a handle (7) on the unpurified side (A) which incorporates the microbe filter (6) by means of a coupling (9). The handle (7) is situated in a switch plate (8) on the unpurified side (A), and is detachably mounted in the housing of the machine, so that the handle (7) together with the microbe filter (6) can easily be removed to change the microbe filter (6). Any excess pressure in the washing compartment of the machine (1) can be adjusted by the ventilation pipe (5).

Title: Heat conservation system in heated building - extracts heat from external cooling path and has heat pump for circulation
Inventor: ROSEN GOERAN
IPC: F24D11/02
Filed: 1976-12-17
Abstract: The system is for the conservation of heat in a heated building during cold periods. The larger part of the external walls of the building have a path, separate from the ambient atmos. for a cooling medium flow. The medium is at a temp. considerably lower than the internal of the building. The heat taken in by the medium is subsequently moved by a heat pump, and returned into the building. The cooling medium consists of air, and is returned cooled into the path at a temp. which is the same as that of the ambient atmosphere, or considerably below it.

Title: Domestic gas explosion preventive fitting - comprises sensors positioned at top of rooms and opening flaps to allow gas escape
Inventor: EICKMANN BODO DR ING
IPC: E04B1/98

Title: Liquid crystal display device - with orienting layers of germanium oxide
Inventor: SEVOSTJANOV VLADIMIR PETROVITS
IPC: G02F1/1337
Filed: 1977-06-15
Abstract: Device comprises a layer of nematic liq. crystals sandwiched between two transparent multilayer blocks. Each block comprises the following layers, listed in order of increasing distance from the liq.-crystal layer: (1) a Ge oxide layer which orients the liq.-crystal mols. so that the major axes of the mols. adjacent to one block are parallel to the block and to each other and are at right angles to the major axes of the mols. adjacent to the other block; (2) a current-conducting layer; (3) a dielectric layer; (4) a polarising layer. Stable and reproducible orientation is achieved with thinner Ge oxide layers compared with Si monoxide; this allows the excitation voltage to be reduced to 1.8V.

Title: Solar type room heating system - has heat exchange liq. circulated between window panes with glass which darkens in sunlight
Inventor: WACK OSKAR DR
IPC: F24J2/04
Filed: 1977-11-03
Abstract: The room heating system using a form of solar heating, has an inner glass pane (3) and an outer glass pane (5) with a space (23) between them for circulating a heat exchange fluid. This is forced by a pump (17) through a bottom opening 7) for discharge through a tap opening (9) to a room heating unit (15). Both glass panes incorporate a substance which becomes dark when subjected to sunshine, so that a large amount of heat is absorbed from the sunshine. In an alternative design, a third glass pane (25) is mounted outside and the space (27) between it and the outer pane (5) subjected to vacuum or filler with an inert gas. This gives better insulation.

Title: Thin-film circuit mfr. - uses tantalum layer on glass substrate with only one heating stage for stabilisation
Inventor: KETTERER GERHARD DIPL PHYS DR
IPC: H01L27/01
Filed: 1977-12-07
Abstract: The manufacturing method for thin-film circuits reduces the number of heating cycles and uses a different type of base material which is not damaged by the stabilisation process. The formation of capacitors is simplified and higher stability is obtained. A high-purity glass or ceramic substrate is used as the supporting structure for a nitrogen-dosed tantalum layer. The 0,3 mu m to 0,5 mu m tantalum layer is etched by a photographic process. Further photo-etching and anodising processes and vacuum deposition follow and a resistor window is etched. A tantalum nitrude resistance layer is deposited, Ni-Cr and gold layers are vacuum deposited. Finally, a temperature stabilisation stage is employed.

Title: Throttle for external ignition IC engine - has profiled section to produce supersonic velocities at low loads to improve combustion
Inventor: MAY MICHAEL G DIPL ING
IPC: F02D9/10
Filed: 1978-02-07
Abstract: The engine is controlled by a throttle (1) in a suction manifold (4) which can be part of a carburetter. Fuel is added to the air stream upstream of the throttle. One side (41) of the throttle blade has a profiled cap (11) placed over it. The profile is such that when the throttle is partly closed the cap and the side of the manifold form a convergent divergent nozzle (8, 12). The fuel air mixture passing through this reaches supersonic velocities in the convergent section. The supersonic velocity breaks up unvapourised fuel particles thus improves the homogeneity of the mixture at low loads.

Title: Pipe joints having a low friction coated short pipe length - bridging the belled ends of the pipe sections to be joined
Inventor: HIRSCH HORST
IPC: F16L27/10
Filed: 1978-03-23
Abstract: Pipe sections, each having belled ends, are joined by a short length of low friction coated pipe the ends of which are supported within the belled ends by sealing rings. The pipe length is sufficiently short to allow axial sliding movement relative to the belled ends. Quoted low friction coatings are of PTFE. enamel or even chromium, and a pref. material for the sealing ring is an ethylene/propylene rubber. The joint accommodates relative longitudinal movements of adjacent pipe sections and also slight relative angular movement without failure. Pipelines including the joints are of particular use in coveying heated media or even water, partic. underground.

Title: Oscillating piston IC engine - has oscillating plate acting as both piston and flywheel to balance output
Inventor: JACKSCHT EBERHARD
IPC: F02B75/28
Filed: 1978-03-30
Abstract: A pipe closed at both ends contains two oscillating plates, fixed to a crank pin of the output shaft. Revolving discs control inlet and exhaust ports to a pair of combustion chambers at the periphery of the closed pipe. The force of the gases expanding after combustion sets the plate into oscillation. The plate acts as a piston to transmit energy to the output shaft and also as a flywheel. The energy stored in the flywheel is in direct relation to the stroke of the oscillating plate and the load on the engine.
