Patent DE-3001205-A1 (DE)
Inventor: MELCHIOR BERND
IPC: C08L33/12
Filed: 1980-01-15
Abstract: PCT No. PCT/DE81/00012 Sec. 371 Date Jul. 30, 1981 Sec. 102(e) Date Jul. 30, 1981 PCT Filed Jan. 14, 1981 PCT Pub. No. WO81/02018 PCT Pub. Date Jul. 23, 1981.The present invention relates to processes of producing transparent foamed plastics, particularly foamed acrylate and methacrylate materials, in the form of e.g. panels, molded articles, or as cores for laminate bodies. Solid beads of transparent polymer material and containing a blowing agent are mixed with a reaction resin, softened by heating or swelling, and expanded to large pore size. During the blowing the beads may be displaced relative to one another. Subsequently the reaction resin is completely polymerized. The so obtained foamed plastics panels, which have large closed cells with contiguous faces and a smooth, non-porous surface, are particularly useful as insulating and building material exhibiting good transparency and protection against loss of heat, especially for greenhouses.

Patent DE-3011949-A1 (DE)
Title: Motor vehicle control for fuel economy - is by having flywheel to restart engine after stopping caused traffic delay esp. in urban driving
Inventor: ZOCHE MICHAEL
IPC: F02N5/04
Filed: 1980-03-27
Abstract: The engine starting system allows frequent starts without drain on the battery or overheating of the starter motor. The system comprises a flywheel, or part of a composite flywheel assembly (S), which remains in motion when the engine has been stopped, by disengaging a clutch (K). When the engine has to be restarted the clutch is energised to engage, and the stored energy in the flywheel turns the engine (M) in order to start it. Clutch and flywheel may form part of the normal drive train or be attached to the opposite end of the engine. The flywheel is typically designed to run for 1 to 2 minutes with sufficient stored energy remaining at the end of this time to turn the engine. With the new arrangement the engine can be stopped whenever it is judged that a traffic hold up will last longer than a few seconds. Fuel economies in urban driving can be achieved by this method.
Patent DE-3013005-A1 (DE)
Title: Stereo signal interference suppressor for community tv appts. - has additional filter and modulator stage converting pilot signal to stereo signal
Inventor: SCHUMANN ALFRED H G
IPC: H04B1/16
Filed: 1980-04-03
Abstract: The interference suppression system for a frequency modulated UHF stereo signal from which a pilot signal is filtered out, is used for a common aerial system for community television. The filtered pilot signal is passed to a further filter system using a narrow band filter and a phase corrector to reduce the remaining interference. The interference force signal then enters a modulator stage in the path of the earlier filter system to obtain the required stereo signal. In an alternative system, the filter system uses a phase-locked loop oscillator with a narrow band filter, the output of the oscillator being modulated to obtain the stereo signal. An automatic level control stage is used to control the oscillator when the pilot signal is not converted into the stereo signal.

Title: Large vertical hot water storage tank - is pressurised to enable water to be stored at temp. above 100 centigrade
Inventor: HERTEL WILHELM DIPL ING
IPC: F24D3/04
Filed: 1980-05-14
Abstract: The tank storing large quantities of hot water is in the form of an upright cylinder with a domed roof. The cylinder is divided into several compartments (1,2) by several partitions(3). The uppermost compartment is pressurised by an inert gas, such as nitrogen supplied through a pipe (14). With several compartments there is a connection between the space near the floor of each compartment, using a pipe (14). This arrangement ensures that there is no pressure difference across any of the partitions. The upper compartment is then pressurised so that the boiling point of the water is raised, thus enabling heat to be stored at higher temperatures than is usual with hot water storage. The tank is preferably made of concrete with a sheet metal liner.
Patent DE-3023552-A1 (DE)
Title: Circuitry for DC supply to monitoring system in armoured vehicle - uses potential-free coupling to on-board power supply for short circuit-to-tank body prevention
Inventor: KRATZENBERG WOLFGANG DIPL ING
IPC: H02M7/06
Filed: 1980-06-24
Abstract: The circuit for supplying power to the tank monitoring system consists of three inverters connected to the on-board quality power supply network which delivers from 18 to 32 volts. The first inverter delivers an alternating voltage of 18 volts which, via rectifiers and L.C. filters is connected through additional D.C. voltage converters to the T.V. cameras, data fade-in and monitoring system. The second inverter, supplying 36 volts, is connected via an L.C. filter and a second converter, to the input of the telemetry transmitter. The third inverter feeds 12 volts to an L.C. filter (27) from where it supplies the picture mixer. The transition from the on-board power supply to the system supply network is thus potential free at the D.C. voltage converter outputs the filters preventing harmonics etc. from reaching the equipment. The monitoring system, whose individual casings are in electrical contact with the vehicle, is in this way, isolated from system disturbances.

Title: Temp. rise and/or pressure redn. reverse changes - in reacted liq. and solid components of heat storage system
Inventor: ABERSFELDER GUENTER DR RER NAT
IPC: F02N19/02
Filed: 1980-08-09
Abstract: A chemical storage system for delivering heat to a consumer unit through a heat exchanger and forced convection liq., with controlled starting of the heat storage and discharge phases, has one reaction component permanently held in a gas-tight reaction vessel, with the other component(s) added during heat discharge or removed during heat storage. The component is liq. in normal temp./pressure conditions, and the other(s) when mixed with the first liberate heat and form a solvate or adsorbate which at increased temp. and/or reduced pressure will revert to its components. The liq. component may be water, alone or mixed with alcohol, e.g. methanol. The solid component may be silica gel, a zeolite, or active carbon. Various aspects of the appts. are also claimed. System is used for preliminary warming of IC engines in cold weather, to reduce fuel consumption and fume-emission on starting. The system is much lighter than known units based on metal hydrides, esp. if one component is vaporised mainly by pressure redn., obviating one heat exchange circuit.

Patent DE-3033748-A1 (DE)
Title: Ground water purification - by distributing oxygen enriched fluid in water bearing strata
Inventor: BRENIK WENZEL DIPL ING
IPC: C02F1/72
Filed: 1980-09-08
Abstract: When ground water is laden with excessive carbon dioxide, heavy metals, ammonium or nitrite, it must be treated before it can be used as a water supply. This is done by distributing in the water bearing strate treated water which has been enriched in oxygen content. For this purpose, pure oxygen or a gas mixture, containing more oxygen than when air is dissolved in the enriched water, can be used. This requires a lesser number of enrichment wells around a pumping well when just air is used for enrichment. If the enrichment well is totally enclosed, the oxygen pressure can be used to accelerate the spread.

Title: Motor-adjustable rear view mirror for vehicles, especially for buses in regular service
Inventor: FLAKE ERICH DIPL ING
IPC: B60R1/06
Filed: 1981-02-05
Abstract: The invention relates to a motor-adjustable rear view mirror for vehicles, especially for buses in regular service, as the frequent exchange of drivers in such buses means that the mirror has to be readjusted relatively frequently, which process is facilitated by means of motor-driven adjustment from the driver's seat. Unlike existing designs of motor-adjustable vehicle rear view mirrors, which mostly require complicated and expensive gears, the object of this invention is to use a wobble plate to transmit movement from the motor to the mirror. A stepping motor which permits step-by-step adjustment can be provided as a drive. If the mirror is held in the casing by means of a soft rubber frame, the mirror is allowed to move in the casing within certain limits. The advantages of the invention are in particular that the wobble plate, which can be produced simply and cheaply, can be used instead of expensive transmission elements (gears etc.).

Patent DE-3119383-A1 (DE)
Inventor: HORN DIETER DIPL CHEM DR
IPC: A23L5/40
Filed: 1981-05-15
Abstract: Finely divided, pulverulent carotinoid or retinoid compositions, in which the carotinoid or retinoid essentially has a particle size of less than 0.5 micron, are prepared by a process wherein a carotinoid or retinoid is dissolved in a volatile, water-miscible, organic solvent at from 50 DEG  C. to 200 DEG  C., if necessary under superatmospheric pressure, within the space of less than 10 seconds. The carotinoid is immediately precipitated, in a colloidally disperse form, from the molecularly disperse solution by rapidly mixing the latter with an aqueous solution of a swellable colloid at from 0 DEG C. to 50 DEG  C., and the resulting dispersion is freed from the solvent and the dispersing medium in a conventional manner.

Title: Device for the fully electrical adjustment of particle spectrometers and imagining systems
Inventor: WOLLNIK HERMANN PROF DR
IPC: H01J37/147
Filed: 1981-07-31
Abstract: The "device for the fully electrical adjustment of particle spectrometers and imaging systems" consists of electromagnetic deflection, focusing and image-error correction elements for ions or electrons, in each case constructed from an arrangement of electrodes or current conductors according to Figure 2. If potentials (V THETA ) are applied to these electrodes, or currents I( theta ) are passed through these current conductors, where; V( theta ) = V10 + V11sin theta  + V12sin2 theta  + ... + V21cos theta  + V22cos theta  + ...; I( theta ) = I10 + I11sin theta  + I12sin2 THETA  + ... + I21cos theta + I22cos2 theta  + ..., then the intensity is adjustable by means of the magnitude of Vij or Iij and the angle  theta  is adjustable by the magnitude of the quotients V1i/V2i or I1i/I2i, where i = 1, 2 ... Fields for the use of the elements described are the adjustment or optimisation of mass spectrometers, ion separators and implantors, electron microscopes or particle accelerators. It appears to be particularly favourable to drive the described elements by means of a process computer - for example by allocating a short-term memory, such as a capacitor, to each electrode - which is charged to the respectively required voltage in accordance with a computation program. <IMAGE>

Title: Air-circulated turning bar, especially for changing the direction of running material webs
Inventor: HANK DIETRICH DR ING
IPC: B65H23/32
Filed: 1981-08-10
Abstract: The invention relates to an air-circulated turning bar, especially for changing the direction of running material webs. In order to avoid having to stop the machine in order to clean turning bars of this type, there is proposed a turning bar, of which the segments soiled by the deposit of dyestuff can be cleaned while the machine is running. This is achieved in that, for the purpose of cleaning, the turning bar mounted rigidly per se can be rotated and locked in the web running direction while the machine is running. Two air-outlet chambers which can be used alternately are arranged in such a way that only the particular air-outlet chamber facing the web is connected to the eccentrically mounted blowing-air conduit. To form the air-outlet chambers, two tube halves having a web and having two end walls joined together respectively from three parts are welded to one another. The proposed turning bars are provided especially for changing the direction of material webs; however, they can also be used, for example, for supporting a web guided in a straight line. They make it possible to use cleaning appliances and are a detail of the plans for automation. <IMAGE>

Title: Method and press for pressing ceramic moulded parts in particular
Inventor: JUNG ROLF DIPL ING
IPC: B30B15/02
Filed: 1981-08-17
Abstract: A method and a press for pressing ceramic moulded parts, which method and press are intended to bring about uniform compression of the moulded parts, even in regions with different cross sections, of a moulded part. To achieve this, the diaphragm base of a pressing stamp is used, which base directly supports a diaphragm and is made of a material which cannot be compressed at the pressures which occur, e.g. with a Shore hardness of between 55 DEG  and 85 DEG , and pressing is carried out by moving the pressing stamp with the membrane support. Thereafter, the deformation of the membrane support occurring during pressing is eliminated owing to the restoring forces of constituent material of the support.
