Title: Non-electrical remote control for bath in steam room - sends signal over light guide using source outside room
Inventor: LANG HELMUT DR ING
IPC: A61H33/00
Filed: 1979-10-29
Abstract: In the interests of safety, the electrical equipment for an air-bubble massage bath is remotely operated by light signals sent over light guides. Pref. the light source is outside the room and light is conducted from it over a guide to the operating control. The control may be a selector which sends light back to the equipment over one or more of a number of other light guides. The returned light may be modulated by interrupting it or by interposing a variable density filter or a colour filter. The electrical equipment is controlled by decoding the outputs of opto-electric transducers which detect the returned light signals. No electrical connections into the steam room are needed. The operating control is still effective when full of water.
Patent DE-2946520-A1 (DE)
IPC: B03D1/24
Filed: 1979-11-17
Abstract: In a flotation basin a flotation zone and a pure liquid zone are formed which are separated by filter means. A liquid containing suspended matter is introduced into the flotation zone via an inlet and subjected to pressure release flotation by saturating pure liquid with pressurized gas under a pressure in the range of 3 to 8 bar and injecting the pressurized gas saturated liquid into the flotation zone in the region of the inlet. The flotated mud accumulating at the surface of the liquid is removed laterally by removal means coacting with the filter means or is removed by means of a combined filtering and removing device together with non-flotatable suspended matter on a filter web circulated or passed through the flotation basin. The mud is predried on the filter web and separated therefrom by redirecting its run, if desired, with assistance by a scraper. The mud falls into a collecting container separated from the flotation basin or its contents by a partition. The outlet is disposed in the pure liquid zone downstream from the filter web or between the runs thereof with respect to the direction of liquid flow. The pure liquid is discharged by a pump controlled in dependence on the inflow.

Title: Fluidised material quantity measuring appts. - has venturi restriction in pneumatic conveyor trough and devices for measuring material level and density in front of and in venturi
Inventor: GOLDMANN WOLF DIPL ING
IPC: G01F1/00
Filed: 1979-12-21
Abstract: The appts. measures the volume of fluidised, fine grain material, such as cement clinker, in a pneumatic conveying trough (1). In the latter is provided a lateral Venturi restriction (2). Measuring elements (4-7) determine the height of the material level and/or its density in front and in the Venturi restriction. The measuring elements may be mechanical, optical, capacitive, or of ultrasonic type. Alternately, a gamma radiator may be used for measuring both the material level and the density simultaneously. This measuring system is accurate and reliable, utilising the height- differential process, supplemented by detection of the material density in front and within the Venturi restriction.

Title: Compact carrier bag for neat storage - has strong base with centre fold to reduce folded dimensions by half
Inventor: MUELLER HANS DIETER
IPC: A45C7/00
Filed: 1980-01-21
Abstract: The side walls (1) of the carrier bag which can be made of plastics or a more expensive material e.g. leather are designed to fold down onto the base (3a,3b). The base itself is divided about a central axis of articulation (4) into two folding halves wherein these two halves can be detachably connected together by fastening devices provided round the edges such as a slide fastener (5a,5b,6) which runs round three sides. Thus when the bag is fully collapsed its size only amounts to half the basic outline of the base providing a flat smooth-walled case easily stored in a handbag for example.

Title: Temporary additional pane for double glazing of motorised caravan - is dished plastics panel held to permanent pane by suction
Inventor: FROEHNER NORBERT
IPC: E06B3/28
Filed: 1980-05-06
Abstract: An additional or auxiliary plastics window pane is intended for window openings esp. in motorised caravans. The pane, which is designed for temporary use during the period when the caravan is stationary, or for permanent use, is placed from the inside against the permanent pane and held there by suction. Opt. for permanent attachement, it may be glued to the permanent pane. The pane is pref. dish-shaped so that only its edges bear against the permanent glass pane and may be fitted with a valve for evacuating its pressure slightly to cause it to stick to the pane. In this way double glazing to provide thermal and acoustic insulation is obtained esp. for the windows in the driver's cabin which are normally of single glass. In an emergency, if the permanent glass pane is broken, the temporary pane may be used as a substitute.

Title: Method and device of recovering energy in cyclic processes employing a gaseous or liquid pressurised medium
Inventor: HAMMELMANN PAUL
IPC: B01J19/00
Filed: 1981-01-21
Abstract: In the method for maintaining a chemical reaction process in a reactor (1) in which dissolved constituents react with one another under high pressure (p1) in a carrier liquid, the carrier liquid containing the reacted constituents is drained off from the reactor and used as the driving agent of two pressure converters (6, 48) from which carrier liquid at the pressure (p1) and containing dissolved reaction constituents is fed to the reactor via pipelines (19, 49) in order to replace the carrier liquid drained from the reactor. For the start-up phase of the reactor (1), an oil-hydraulically driven pressure converter (2) is used whose plungers feed carrier liquid containing reaction constituents into the reactor (1) via a pipe (3). The pressure converters (6 and 48) have differential pistons for driving the plungers. The carrier liquid which is fed to the pressure converter (48) as drive medium has a pressure (p2) which is reduced in relation to the effective areas of the differential pistons of the pressure converter (6) and which is applied to the large effective areas of the differential pistons of the pressure converter (48). Arranged between the pressure converters (6 and 48) is a degassing container (46). Furthermore, a degassing container (52) is connected downstream of the pressure converter (48). <IMAGE>

Patent DE-3103281-A1 (DE)
Title: Material cabinet
Inventor: HEUKELBACH ALEXANDER
IPC: A47B88/04
Filed: 1981-01-31
Abstract: The invention sets out from material cabinets in which shelves are placed which are manually adjustable. These shelves lie on shelf supports which, in turn, are suspended in adjusting strips in the housing. Since loose shelves of this type no longer fully satisfy the requirements, a change was made to installing extensible compartments, such as pull-out shelves and drawers, fixedly in the housing from the outset. Individual height-adjustability thus became impossible. According to the invention, the extensible compartments, that is to say pull-out shelves and drawers, are now installed height-adjustably in the housing with the aid of specially designed guide supports. <IMAGE>
