Patent DE-2151295-A1 (DE)
Title: Plastics tube extrusion nozzle - with precipitation spaces for impurities restricted to removable nozzle body
Inventor: PIOTROWSKI HEINZ
IPC: B29C48/09
Filed: 1971-10-14
Abstract: An extrusion head for plastic tubing comprises a feed duct which widens out at its end towards the nozzle around the commencement of a central torpedo; the cross-section of this feed duct remains constant over its entire length right up to the commencement of the torpedo. Pref. the nozzle core immediately follows the torpedo in cross-section, then widens out. The overall result of this non-widening of the feed duct and positive taper of the annulus within the nozzle doby around the nozzle core causes the precipitation of impurities to be restricted to the nozzle body, which is easily removable for cleaning.

Patent DE-2229842-A1 (DE)
Title: Bobbin clamp - with sprung sleeve on spindle and gripping segments
Inventor: CZECH MILOSLAV
IPC: B65H54/54
Filed: 1972-06-19
Abstract: An operating handle, in conjunction with a spiral groove, forces the end of a clamping sleeve against its holding spring to loosen the grip of conical segments. When the bobbin sleeve is inserted before the start of cross-winding, the operating handle is returned which allows the segments to reassert themselves and exert a gripping pressure on the inside of the bobbin sleeve. Thus the bobbin is securely held during high-speed winding.

Title: Monotopic di- tri-fluoropolyhaloethanes by rearrangement - using mixt. of mixed aluminium halides as catalyst, with thermodynamic stability, fast reaction and simple cheap catalyst
IPC: C07C17/358
Filed: 1972-09-15
Abstract: Cpds of gen. formula CF2Z.CZ3 or CF3.CZ3 (in which Z is H, Cl, Br or I) are produced by rearrangement of cpds of gen. formula CFZ2.CFZ2 or CF2Z.CFZ2, using as catalyst a mixt. of Al halides of the type AlXY2 and AlX2Y (in which X and Y are Cl, Br or I, which occur in the catalyst mixt. in pairs). Monotopic prods. are obtd., which are more stable thermodynamically than the ditopic isomers. The Al halide mixts. are much more soluble than AlCl3 in the reaction mixt., hence reaction is faster. They also save 50% of expensive bromine cf. AlBr3, whilst retaining all the advantages of AlBr3 over AlCl3. They can be prepd. simply and eliminate the unpleasant manipulation of finished Al halides, whose catalytic efficiency is reduced by atmos. moisture.

Patent DE-2358428-A1 (DE)
Inventor: SUGIMURA NOBUYUKI
IPC: F16K17/38
Filed: 1973-11-23
Abstract: A novel structure of pressure container is disclosed, wherein a safety valve is provided within an air injection valve of said pressure container, whereby even when the ambient atmosphere of said accumulator has been heated up to a high temperature because of a fire and the like, bursting of said pressure container may be prevented. A valve seat is formed inside of a valve casing and a fusible valve member is brought in contact with said valve seat, so that when the ambient temperature of said pressure container has been raised said fusible valve member may fuse to permit the gas pressure in the pressure container to be discharged to the exterior of the container. Said fusible valve member is filled within a hollow space of a cylindrical valve stem and said valve stem is provided with a passageway or passageways communicating with the interior and exterior thereof, so that when the fusible valve has been fused, the gas within the gas pressure container may blow away the fusible member in a fused state through said passageway or passageways to the exterior of the container.

Title: Graphite tubes for flameless atomic absorption spectroscopy - impregnated with coal tar to seal pores and cracks
Inventor: HUBER BERNHARD WERNER
IPC: C04B35/52
Filed: 1974-04-27
Abstract: Graphite tube used in flameless atomic absorption spectroscopy are rendered pore-free by impregnation with coal tar at 100-150 degrees C (pref. 120 degrees C) and heating with exclusion of air. The temp. is slowly raised (pref. 5 degrees C/hr.) to 1000-1500 degrees C (pref. 1200 degrees C), and then the tube is heated at 2200-3000 degrees C (pref. at 2500 degrees C) for about 100 hrs.

Title: Intermittently operating continuous-wash washing machine - ensuring efficient transport of washing from zone to zone
IPC: D06F31/00
Filed: 1974-05-20
Abstract: Intermittently working continuous-wash washingmachine, esp. for loose loads of washing, with a washing drum open on both sides housed horizontally and rotatably divided into washing zones in which the washing it treated separately, has a draw surface of trapezoidal shape formed in one piece with a transport surface in such a way that the level draw surface extends directly into a conventional curved transport surface whereby a part of the draw surface and the whole transport surface at one of their ends join the passage opening of one of the bordering baffle plates, whilst the draw surface and the transport surface are connected at their other end with radical spacing from the sloping opposite end of the passage opening of the other bordering baffle plate to the latter. The draw surface further possesses a baffle, projecting over the curved transport surface on its rear side-bordering on the baffle plate, to which it is joined with radical spacing from the passage opening. The entire load of washing is safely transported quickly from one zone into the other during a rotation of the machine contrary to the direction of rotation during washing. It is thus ensured that during the rotational direction of washing no pieces of washing return to the previous zone.

Title: Variable resistance with actuator producing non-linear characteristics - has cone on spindle engaging second reversed cone with wiper attached
Inventor: NISHIOKA MATSUO
IPC: H01C10/14
Filed: 1974-09-06
Abstract: The variable resistance with an actuator (2) is for changing the value and a mechanism for shifting the wiper (7). Non-linear characteristics are obtained in that when the actuator is adjusted at a constant speed while the wiper is being shifted at a variable speed. A cone (3) with a knurled (4) outer surface is attached to the bottom end of the actuator spindle. This engages a second cone (6) mounted in the reverse manner to the first. The second cone drives the wiper contact which is on the under surface, making frictional contact with the surface of the resistance element which is enclosed in an insulated housing (1).

Title: Elemental sulphur prodn. from gases contg. sulphur dioxide - by thermal reduction with gaseous hydrocarbon partly burnt in air
Inventor: FIEBIG SIEGWARD ING GRAD
IPC: B01D53/74
Filed: 1974-09-30
Abstract: Prodn. of elemental sulphur from SO2-contg. gases, in particular regeneration gases from a desulphurisation plant, by thermal reduction with a gaseous hydrocarbon, esp. CH4, which is partly burnt in an O2-contg. gas, esp. air; cooling to 200-460 degrees C and catalytic conversion of S-contg. cpds. to elemental S, followed by condensation and sepn. of S, is improved in that a regeneration gas contg. 10-100 vol. % SO2 is introduced into a reaction chamber heated to 850-1250 degrees C and reacted with the hydrocarbon and oxygen (the latter in a substoichiometric quantity). Alternatively, the hydrocarbon gas is preliminarily partly burned in absence of SO2, which is subsequently reduced virtually in absence of O2 (0.2 vol. %). Carbon-free sulphur is produced at relatively low temps. Process is economical.

Title: Chain links for necklaces - are of tubular shape and are made from paste which may be hardened and then lacquered
Inventor: SCHUELZKE PETER DIPL ING
IPC: F02D41/08
Filed: 1974-10-23
Abstract: An electronic control unit regulates the opening period of one or more solenoid injection valves and incorporates a multi-vibrator, preferably monostable. The duration of the output impulses from unit vary with one or more engine parameters, particularly the vacuum downstream of the throttle butterfly. An electronic extension stage delivers an extension impulse attached to the multivibrator impulse and whose length depends on that of the latter. Means are included for enrichment of the fuel/air mixture when warming up. The unit has a switch coupled to the throttle butterfly of the engine, and this assumes one of its two positions only when idling, but otherwise is in the other position.
