Title: Hydraulic disc brake for automobile - uses plate piston sliding on fixed axle sleeve behind piston face housing sleeve flange to form ram cylinder
Inventor: LUCHIER JEAN-JACQUES
IPC: F16D65/847
Filed: 1979-12-29
Abstract: The hydraulic disc brake may be used on a free automobile wheel, using an axially displaceable circular plate (16) as a piston to push the brake lining (17) onto an inboard radial face (10) of the hub (2). A flanged (11) sleeve (9) houses the inboard end of the fixed axle (1) and also locates the piston (16) slidably on its barrel. An axial flange (21) projects from the rear piston face (15) to house the sleeve flange (11) and define a closed volume which constitutes the ram cylinder. Piston plate bore grooves (19, 22) locate sealing rings (18, 23) the hydraulic fluid being introduced through an internally threaded bore (25).

Title: Sterilisation of surfaces esp. hospital equipment - by application of a low temp. gas plasma contg. an aldehyde under sub-atmospheric pressure
Inventor: BOUCHER RAMOND MARCEL GUT
IPC: A61L2/14
Filed: 1980-01-10
Abstract: Surfaces are sterilised by contact with a low. temp. gas plasma contg. >=10 mg/l of an aldehyde (I) under sub-atmospheric pressure, esp. 0.1-10 mm Hg. The gas plasma is produced eg. by electromagnetic excitation using a discharge in the high frequency range of 1-100 MHz or the microwave range 100-300,000 MHz. The gas used is eg. O2, argon, He, N2, CO2, N2O or a mixt. of these. (I) is eg. formaldehyde, acetaldehyde, glyoxal, malonaldehyde, propionaldehyde, succinaldehyde, butyraldehyde, glutaraldehyde, 2-hydoroxyadipaldehyde, acrolein, crotonaldehyde, benzaldehyde or furfural. The process is esp. useful for sterilisation of hospital equipment. The process gives rapid sporicidal action, leaves no toxic residues on the surface and is not environmentally harmful.
Patent DE-3003618-A1 (DE)
Title: Cooling bed for tubes - with reciprocating beams and intermittently moving chains with roller flights
Inventor: SCHULZ ALFRED
IPC: B21B43/10
Filed: 1980-02-01
Abstract: A cooling bed for tubes consists of parallel beams which lie at a slight ascending angle and are reciprocated. The tubes which lie across these beams are moved forward by intermittently moving chains which rest through rollers on guide rails. Flights on the chains protrude above the beams and separate each tube from the next by a roller. The combinations of the two movements have the result that the tubes are not only moved forward along the cooling bed, but also turned so that no tube distortion is caused by un-uniform cooling.

IPC: C01B11/16
Filed: 1980-10-29
Abstract: Sulphuric acid or sulphates are added to nitric and/or perchloric acids so that Pb present in the latter is pptd. as lead sulphate, and is then removed. Barium ions are next added to ppte. any residual sulphate in the acids as barium sulphate, which is also removed te leave purified HNO3 and/or HC104. The residual sulphate is pref. pptd. by adding solid barium cpds., esp. barium carbenate. The process is used esp. to remove Pb from acid employed to dissolve Pb solder used in mfg. TV tubes. TV tubes have an image screen which is bonded to a conical bulb by a Pb solder. When the tubes are faulty, the screen is remeved by dissolving the solder in HNO3 and/or HC104.

Title: Method for the extraction, transportation and distribution of fodder and apparatus for carrying out this method
Inventor: WEICHEL ERNST
IPC: A01F25/20
Filed: 1981-07-23
Abstract: In a method for the extraction of fodder from haystacks, mobile silos or the like, cuboid blocks are cut out from the fodder deposit by means of a tractor-mounted appliance and these are transported to the feed points in the stables and set down there. So that the fodder table or the like to be negotiated by the tractor or by other appliances remains free and is not obstructed by the fodder blocks, it is proposed, according to the invention, that the blocks be pivoted through approximately 90 DEG  on a fodder table and set down in such a way that their longitudinal axis is approximately parallel to the longitudinal axis of the tractor. It is also beneficial, here, if the blocks are displaced laterally into a position outside the tractor track.

Title: Method for splitting a flowing gas/liquid mixture into a plurality of component flows
Inventor: REDDEMANN BERNHARD DIPL PHYS D
IPC: F25B39/02
Filed: 1981-08-08
Abstract: It is known for the purpose of splitting a flowing gas/liquid mixture into a plurality of component flows firstly to separate the flowing mixture at a substantially reduced rate of flow with the use of the gravity field into a lower lying liquid phase and a gaseous phase situated thereabove, and to extract and unite gaseous and liquid component flows, respectively. The known methods are, however, still relatively complicated and, in particular, very expensive in terms of design. It is proposed for the purpose of overcoming these disadvantages to extract component flows in a "liquid-gaseous" fashion in the region of the interface which is produced. Suitable for carrying out the method is a shell-and-tube (tube-shell) heat exchanger which is characterised in that the tubes (1) project outwards from the tube plate (sheet) (2) into the inlet header (3) (i.e. are lengthened), and in that all the inlet ends (7) of the tubes (1) are arranged in a horizontal plane, taking account of the operating setup of the tube-and-shell heat exchanger. <IMAGE>
