Patent SE-7905966-L (SE)
IPC: F01D1/02
Filed: 1979-07-09
Abstract: A continuous cycle dual rotor propulsion system wherein Freon R12 with synthetic motor oil added to it circulates through a closed circuit conduit in which a pump-compressor 32, heat generator 36, propulsion unit 12 and condenser 30 are connected in series. The fluid is super-heated in the heat generator and the gas so generated is directed through a narrow, generally rectangular flow duct through the propulsion unit where it impinges upon the blades of a pair of rotors 14, 16 rotatably mounted therein. The flow duct is tangential to each of the rotors and the rotor blades conform in outline to the cross-sectional shape of the flow duct. The rotors are geared to a common drive output which, inter alia, drives the pump-compressor. <IMAGE>

Abstract: A closure device for a bottle or the like wherein the closure device which, in its closed condition, comprises a pressure ring and a claw cap is fabricated of one-piece in that the pressure ring is connected with the claw cap by means of webs which are disposed between its engagement portions and the roof wall of the claw cap. By pressing the pressure ring downwardly over arms and claws of the closure cap, while tearing the webs, the claws are pressed against the underside of a mouth bead of the neck of the bottle and are pressed into a constricted portion of the bottle neck. By rotating the pressure ring such that its engagement portions or parts depart from the U-shaped claws and by lifting the same it is possible to remove the closure cap from the dispensing or pour opening of the bottle neck, since the engagement parts upwardly raise the claw cap at a lower edge of the roof wall of such claw cap.

Abstract: When painting lines or the like on roads, for example, the surface is first freed from water and dirt either mechanically or by means of compressed air. Compressed air is then directed toward the surface one or more times with control of the compressed air's speed over the surface, its vapour pressure and its temperature in such a way that optimal moisture emission is achieved while the surface temperature is kept at a low value. The surface layer is then warmed to such a temperature and depth that moisture travel turns inward. The paint or coating is then applied before the temperature has decreased to such a value that moisture travel once again turns outward.

Abstract: The effects of vertical perturbations of a gramophone disc record surface resulting from e.g. record warp and rumble are reduced by sensing the perturbations and compensating therefor by closed loop or open loop means. Thus a reference path adjacent the groove tracked by the main stylus may be tracked, e.g. by a supplementary stylus riding on the lands of the disc surface or photoelectrically. A reference path signal may then be derived by a reference path sensor 104, and this signal is then applied to a preferably closed loop servo 95, 98, 100, 112, 114, 97 which moves the disc 9 itself up and down to tend to null out the reference path signal. Alternatively the compensation is applied by causing the tone arm to track the reference path by a servo technique or by mechanical coupling within the cartridge or electrically by subtracting the reference path signal from the main stylus signal, or by a combination of such techniques. <IMAGE>

Abstract: Modern Yankee machines for thin paper qualities give the possibilities at present to approach machine speeds of 200 m/min with a specific weight of about 17 g/m<2>. The machine consists of a forming section (often called a twin wire former), a web transfer section (in which the formed sheet is transferred to the press felt), and a suction press roll over which the press felt with the web is turned so that the web presses against the warm Yankee cylinder. In order to increase line speed without encountering problems, the web is now formed between a felt (2) - or a press fabric - and a forming fabric (3). The forming unit, consisting of the felt and fabric is placed in such a position in relation to the press roll (8) that the web (10), when it is separated from the forming fabric (3), is transported by the felt (2) and can be led into a press nip against a Yankee cylinder (7) surface along a straight path.

These filters simultaneously filter out from the signals from the film a frequency band of 0.1-3HZ for passage to a respiratory recording appts. and a frequency band of 10-30 Hz for passage to a ballistocardiographic recording appts. Alarms are a part of the euipment, and function when the frequencies filtered out for respiration and pulse are below predetermined levels.
