Patent DE-2037382-A1 (DE)
Title: Double walled heat exchanger - with continuous cooling flow through wall space at hot end
IPC: F28D7/16
Filed: 1970-07-23
Abstract: A heat exchanger, comprising a rotationally shaped housing and a tube bundle, with the first heat exchange medium (dropping in temperature) passing through the housing around the tubes and the second (rising in temperature) passing through the tubes, and with a double wall at the inlet end of the housing wigh its internal space connected to the main chamber of the housing, has this double wall space connected to the main chamber at two different positions, so that different pressures obtain in the first medium and these two positions, thus ensuring continuous circulation of relatively cool first fluid through the double wall space, and so limiting the maximum temperature of the heat exchanger wall at the hot end.

Title: Plastic packaging bag prodn - by transversely welding molecularly orien-tated thermoplastic tube using infra-red heater
Inventor: SEIBERT WILHELM
IPC: B29C65/78
Filed: 1973-02-22
Abstract: A molecularly orientated continuous flattened plastic (e.g. polyester) film is passed between pref. circular resilient clamping plates which can be moved together by associated rams and one of which can be cooled, and an infra-red heater is lowered intermittently (by e.g. a ram) so that infra red rays can be focussed (e.g. by a reflector on the film adjacent the clamping plates) to form a pref. arcuate weld line across the tube. Pref. the tube is cut adjacent the weld line by a cutter blade or biting about the centre of the clamping plates to produce individual bags which are stacked. The bags are used for packaging food (e.g. chickens) and the plastic is molecularly orientated and therefore stronger and the single weld line which is produced is also stronger.

Patent DE-2404217-A1 (DE)
Title: Vibration stabiliser for high-speed rotor - has damping ring revolving with rotor without any contact with surroundings, for use in centrifuges
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: B04B9/12
Filed: 1974-01-30
Abstract: The Parent Patent describes a stabiliser for high-speed rotors, e.g. centrifuges, spinning machine spindles, or revolving wheels in satellites, in which >=1 bearing is a magnetic bearing without any contact with the surroundings. The stabiliser consists of a damping system revolving together with the rotor and without contact with the surroundings, and in particular of a damping ring revolving with the rotor and connected to it elastically by wire or spring systems, so that it can execute relative movement to the rotor (transversely and optionally also longitudinally), these movements being damped hydraulically, pneumatically or by eddy currents. In this addn. the damping ring is also capable of executing movements relative to the rotor which are rotational movements about its axis. As in the Parent Patent, a positive damping effect is obtained by the mechanical connection of the damping ring to the rotor, and the damping does not rely merely upon magnetic forces, which are normally inadequate. The addn. provides the additional advantage of permitting very high damping at low rotor speeds, where both the rotor and also the damping system may have a resonance frequency giving rise to vibrations quite different from those at high speeds. At higher speeds, the damping coefft. is again reduced to its lower value as in the Parent Patent. The apparatus is thus partic. suitable for ultra high speed or supercritical centrifuges.

Title: Manipulator esp for reactor pressure vessel inspection - has folding cable tray which adjusts to position of outrigger
Inventor: FIGLHUBER DIETGAR DIPL ING
IPC: G21C17/01
Filed: 1974-04-11
Abstract: A manipulator, esp. for a nuclear reactor, comprises a mast with a movable arm mounted on it; the free end of the arm carries test equipment, esp. an ultrasonic inspection head, connected to flexible cables or tubes. A folding bridge is connected to the mast and the other end of the arm, supports the cables and tubes, and adjusts its shape to accommodate the position of the arm. This bridge may consist of three bars, hinged to one another and the arm and mast, the central bar being guided on the arm; or of two bars, attached at their outer ends to transverse out-riggers projecting from the arm. The bridge may be of ladder-type construction. The manipulator is used for regular inspection e.g. of the internal surfaces of open-topped nuclear pressure vessels. The folding bridge protects the cables and tubes and results in long life without maintenance.

Abstract: Mononitrate esters of diols (e.g., 11, 18-dihydroxy-pregna-1, 4-diene-3, 20-dione 18-nitrate) are produced by subjecting a nitrite ester of an alcohol having an H-atom which is conformationally adjacent to the OH gp. or is capable of so being and in which the atoms linking the H-atom and the OH gp. comprise >=2 adjacent atoms which form part of a ring (e.g., pregna-1, 4-dien-11 -ol-3, 20-dione 11-nitrite) to photolysis is the presence of molecular oxygen, forming a corresp. cpd. in which the specified H-atom is replaced by a nitroxy gp. The diol mononitrate prodts. are useful as inters., partic. in the steroid field. The reaction can be used in the prepn. of 19-hydroxy-steroids from 6-hydroxy-steroids, 18-hydroxy-steroids from 11- and 20-hydroxy-steroids, and 32-hydroxy-steroids from 7-hydroxy-steroids. 18-Hydroxy-steroids are useful as inters. for aldosterone derivs. and aldosterone antagonists, and are also effective in hypertension. DELTA1-18-Hydroxy-steroids are useful in the prepn. of tritium-labelled 18-hydroxy-steroids such as 18-hydroxycorticosterone and 18-hydroxy-11-deoxy-corticosterone which are of use in metabolic and diagnostic studies.

Title: Press safety clutch with actuating handle - has combined hydraulic and pneumatic element in the actuating linkage
Inventor: PEDDINGHAUS CARL ULRICH DR
IPC: B23Q5/54
Filed: 1974-06-11
Abstract: The press clutch is engaged by a lever system in conjunction with the safety device which ensures that the drive is coupled with the machine only during machining. A rod of the linkage is replaced by a damping cylinder with a piston which has axial openings. The piston rod passes through one end of the cylinder and it is connected to a spring loaded manually actuated handle. The cylinder is filled with a damping liquid. The cylinder has also an additional floating piston which separates the liquid in the cylinder from a gas filling in the cylinder. This damping element ensures that the actuation movement is carried out at a given speed for engaging the clutch and only one movement of the actuating handle is needed.

Title: Concentrating trace components in gases, e.g. air etc. - by low temp. cooling, followed by controlled evapn. through analysis equipment
Inventor: ANGERER JUERGEN DR
IPC: G01N33/00
Filed: 1974-07-01
Abstract: In the expansion of trace components enriched by condensn. in the low temp. field, in which liq. N2 is regarded as the max. b.pt., all matls. of higher b.pt. than that of N2 are condensed and simultaneously enriched since a greater amt. of sample can be taken up. The sample enriched as above has a rising characteristic pressure with rising temp. and produces, in metering to a suitable sepg. system, a vapour-pressure dependent gradient; and the pressure gradient favours the sepn. of the whole mixt. with careful treatment of the matl. since the total process corresponds to the natural state of the matl. and is to be carried out without the aid of matl.-changing agents.

Inventor: SCHULLER HERI DIPL-ING
IPC: A62B1/14
Filed: 1974-07-08
Abstract: A lowering cable (2) is taken up by the user after each stage of lifting using a braking post (9) a disc brake (11, 15, 17) and cable lock (22, 23). A lifting cable (5) with pulley (6) is braked by clamps (30), guided by laterally open eyelets (31) and belayed by a cleat (3) in intervals.

In the case of entering a shaft from above, the lifting cable is guided upwards over a second pulley (49) behind which it is attached so that the device may be pulled up out of the shaft by the cable end (50) by another person in case of emergency.
