Patent DE-3000568-A1 (DE)
Title: Plasticising synthetic material with myristic acid ester - with low toxicity, esp. for medical applications
Inventor: SIGDELL JAN-ERIK DR
IPC: B29B13/00
Filed: 1980-01-09
Abstract: Synthetic materials are plasticised by addn. of a myristic acid ester. The claimed synthetic is PVC. The esters include isopropyl myristate (claimed), propyl myristate, and propyl tetradecanoate. The ester may be added to the molten synthetic, to granules of the synthetic before melting, or to a soln. of the synthetic. Alternatively, the ester may be allowed to diffuse into the synthetic after this has become rigid because of extn. of a phthalate plasticser; or, it may be added during polymerisation. The plasticiser has low toxivity, Even with about 20% of plasticiser, PVC remains glass-clear. The plasticised synthetic can be melted and solidified again without loss of flexibility or development of cloudiness. PVC is stronger than when a phthalate plasticiser is used. The synthetic can be used in medical applns. e.g. for infusion tubing, and for tubing and pouches for blood.

Patent DE-3048704-A1 (DE)
Inventor: THIEME HANS DIPL PHYS DR
IPC: G03B27/58
Filed: 1980-12-23
Abstract: In modern high-performance roller copiers, the paper course is frequently monitored by light barriers having an opto-transmitter (6) and an opto-receiver (7), which operate in a radiation range largely outside the sensitivity range of the copying material. In order chiefly in the case of highly sensitive copying materials to avoid the risk of exposing said material by the opto-emitter, the opto-emitter is connected in such a way that it emits radiation only from time to time, and the opto-receiver is connected to an evaluation device which produces a stationary display potential by evaluating the pulses of the power supply (8, 9) applied to the emitter. <IMAGE>
Patent DE-3100143-A1 (DE)
Title: Method for the continuous casting and rolling of metallic workpieces in line
Inventor: OPPERMANN WILLI-FRIEDRICH
IPC: B21B1/46
Filed: 1981-01-07
Abstract: The method is suitable for the economic production of semi-finished products in the form of round, hollow and polygonal sections from metallic materials. The direct succession of melting, horizontal casting and rolling in just one line frees the method from the need for any intermediate transfer facilities, as required hitherto. A transfer channel which consists of thermally insulating materials, is closely matched to the cast section and connects the individual work stages, ensures that the rolling stock retains its primary energy introduced during the melting process sufficiently to ensure that only a little additional energy or none at all is required for the rolling process.

Patent DE-3103335-A1 (DE)
Title: Combustion-steam engine
Inventor: GUSSET WALTER
IPC: F02B41/06
Filed: 1981-01-31
Abstract: The invention relates to an internal combustion engine and a steam engine, which generates driving force by very rapid combustion of a mixture of air and fuel and very rapid vaporisation of a liquid, for example water. The steam engine is fitted to the cylinder head of the internal combustion engine. The pistons of the two engines are connected to one another by a piston valve rod. The piston in the steam engine is located inside an elongated hollow piston, which transmits the force of the water vaporisation by way of the hydraulic fluid to the piston. When the fuel-air mixture is ignited in the internal combustion engine the injected water in the steam engine is simultaneously vaporised by the hot exhaust gases. When the piston slides down and when the piston slides up the fuel-air mixture is blown into the internal combustion engine by a fan. The blown-in fuel-air mixture then expels the hot exhaust gases out of the internal combustion engine through the connecting duct into the steam engine, the cooled exhaust gases and the water vapour from the steam engine being forced through the outlet into the exhaust. When the outlet in the internal combustion engine is closed by the piston sliding up and the outlet in the steam engine by the piston sliding down, the fuel-air mixture in the internal combustion engine and the hot exhaust gases in the steam engine are compressed.
Patent DE-3112499-A1 (DE)
Inventor: ZUCHTRIEGEL ANTON
IPC: H02M7/533
Filed: 1981-03-30
Abstract: A fluorescent lamp control circuit which provides power at high frequency, for example in the order of 35 kHz, includes a push-pull oscillator circuit having two transistors (T1, T2), an inductance element (L1, L1'), and a capacitor (C1, C1') to supply the lamps (3, 3'). To prevent dangerous high voltages upon removal of the lamp load, connected to the oscillatory circuit and to the series resonance circuit, upon removal of failure of a lamp, a protective circuit is provided formed by a thyristor (TH) connected to short-circuit at least one of the transistors (T1) of the oscillatory circuit. Control energy is derived directly from the high-voltage supply by a rectifier (D1, D1') connected to the inductance (L1, L1') of the series resonance circuit, so that sufficient and reliable switching energy for the protective thyristor (TH) is always available, the firing criterion therefor being determined by the breakdown voltage of a breakdown element such as a diac (22) connected to a voltage divider (20, 21) and receiving its control voltage also from the high-voltage connection of the series resonance circuit (4) including the inductance, which also feeds the power supply capacitor (C3) for the thyristor (TH).
Patent DE-3117041-A1 (DE)
Title: Rake tedder
Inventor: ANDERSSON SVEN
IPC: A01D89/00
Filed: 1981-04-29
Abstract: A rake tedder (1), which is intended to be arranged in front of the pick-up device (2) of a self-loading hay truck (3), comprises a plurality of tines (21) which are arranged in groups and which are movable in endless tracks, in order to bring together hay or another crop lying on the ground, to form a relatively narrow swath in front of the pick-up device. So that the rake tedder takes effect within a relatively wide zone, it comprises two rake units (10a, 10b), the tines (21) of which move on elongate paths which each extend essentially at right angles to the direction of travel of the hay truck and which form mutual extensions of one another. The rake tedder thereby acquires a larger extension in the transverse direction than is desirable, and in order to overcome this disadvantage, the two rake units (10a, 10b) are respectively pivotable upwards about essentially horizontal pivot axes (12) which are approximately parallel to the direction of travel of the hay truck. <IMAGE>

Title: Automatic lay-up machine for producing components from fibre-reinforced materials
Inventor: AUER PETER
IPC: B29C70/38
Filed: 1981-05-05
Abstract: The invention relates to automatic lay-up machine for producing components from fibre-reinforced materials. The roving is fed to a component mould via a lay-up head which is pivotable about a spindle. The lay-up head has a plurality of deflector rollers to feed the roving to a lay-up roll. The lay-up roller is mounted on the spindle at one side in such a manner that the spindle is located in the direct vicinity of an edge of the roving fed to the lay-up roller. By means of this design of the lay-up head, rovings may be laid-up even in component moulds having surfaces with alternating inclination. The roving is preferably applied to a carrier film, depending on the type of component shape, either as a continuous roving or in roving sections which are separate from one another on the continuous carrier film. This fibre strand is guided in the roller mechanism of the roller head in such a manner that only the carrier film runs over the rollers, so that these rollers are not soiled by the synthetic resin with which the roving is impregnated. <IMAGE>

Title: Process for the continuous regeneration of chromating solutions for zinc, cadmium and similar metal coatings
Inventor: HUSS RAINER DIPL CHEM DR
IPC: C23C22/86
Filed: 1981-09-28
Abstract: Process for the automatic regeneration of chromating solutions, for example for zinc and cadmium coatings, with the aid of which a predetermined composition, virtually constant as a function of time, of the chromating solution is achieved with regard to Cr<6+>, Cr<3+>, H<+> and the metal ions, such as, for example, Zn<2+> or Cd<2+>, and residual anions and residual cations. For this purpose, a continuous analysis of the Cr<6+>, Cr<3+> and H<+> content of the chromating solution is carried out, and replenishing solution is metered in as a function of a comparison between ideal and actual values, while the Cr<3+> and, if necessary, for example Zn<2+> or Cd<2+> components are removed, for example via a cation exchanger. <IMAGE>
Patent DE-3140766-A1 (DE)
Title: Liquid distributor for mass transfer apparatuses
Inventor: SCHREINER HERMANN PROF DIPL IN
IPC: B01D3/00
Filed: 1981-10-14
Abstract: The invention solves the problem of distributing, uniformly and appropriately for the amount of liquid, a small liquid stream over a larger or smaller cross-section of a gas-liquid contact apparatus with avoidance of some disadvantages of known distributor designs. The distributor is located outside the column, which results in the following advantages: the distributor does not block the gas stream, it can be constructed small always with the same dimensions even when the column cross-section is large, and it is accessible outside the column for controlling and cleaning. The controllability, corresponding to the liquid throughput, is achieved by the individual distributor streams being adjusted by regulating needles and distributor pipes which are fixed to commonly drilled plates and being passed by means of hoses or pipes into the interior of the column.

Title: Clock with a sectionally controllable display
IPC: G04G9/00
Filed: 1981-10-27
Abstract: In a clock (1) with a sectionally controllable display (3), for example for representing various items of information derived from time, or for selectively altering the instantaneous time display, the display information that is altered with respect to the standard display is to be represented in a more obvious and comprehensible fashion. For this purpose, the display (3) is constructed on a display section (2) having an electrically reversible perceived colour display. As a result, it is possible either for individual parts (numerical displays or pointer displays) to have their colour perception altered with respect to the remainder of the display (3) in order to lend visual emphasis to the alteration in the information, or for individual regions of the information background to have their colour reversed when the information representation is not influenced by colour. <IMAGE>
