Title: Hot pressing plate for bonding conveyor belts - has three types of heating zones assuring uniform temp. distribution
Inventor: THIES PETER DIPL ING
IPC: B29C33/02
Filed: 1980-10-25
Abstract: Pressing plate consists of a peripheral rectangular or rhomboidal frame and diagonal ribs or webs (2), a front heated plate, a rear cover plate and tubular heating elements meandering within the web and frame structure. The heating area of the plate is subdivided into central heating zones (MH), edge heating zones (RH), and corner heating zones (EH). Central heating zones (MH) are each elongated parallelograms or rectangles having a rib (2) along their central longitudinal axis (L), and one corner (6) at each end extending as far as the peripheral frame member; the edge heating zone (RH) and corner heating zones (EH) complement the remaining areas. The heating elements in the spaces (A) between adjacent ribs of the central heating zones (MH) each belong to one half of the adjacent zones: the heating elements also run through the intermediate zones between the ribs (2) and the peripheral frame. The specific heating output per unit area is equal in all three types of zone. Used in heating or vulcanising plates for the jointing or repair of conveyor belts. The arrangement assures a very uniform distribution of heat.
Patent DE-3043309-A1 (DE)
Title: Stopping engine of vehicle with automatic transmission - also restarting by electronic circuit controlled by switch on brake pedal
Inventor: OJELID GOERAN
IPC: F02N11/08
Filed: 1980-11-17
Abstract: The circuit gives automatic starting and stopping of the engine when the vehicle is temporarily halted, for example at a traffic light. The restarting of the engine is initiated by operation of the brake pedal to give an impulse to an electronic control circuit. By this means no movement of the ignition switch or other hand operated device is needed, and there is no risk of the vehicle rolling during the restart. In a typical circuit a threshold device (51) turns on a thyristor (50) when, after application of the brake pedal (60), the engine speed falls to the idling level for a set time. By charging a capacitor (37) this thyristor (50) turns off a conducting thyristor (13) thereby interrupting the supply to the ignition system (22), and the engine stops. To restart the brake pedal is momentarily released and then reapplied. The impulse thus set up by a switch (60) on the pedal fires a thyristor (12) in the starter motor (23) circuit. It remains in conduction until the dynamo voltage (25) rises, as the engine runs up, and biases the thyristor (12) off again.

Title: Interference immune connector between transducer and receiver - comprising light guide cable with terminations containing electrical to optical signal converters
Inventor: ROHNER PETER DR RER NAT
IPC: H04B10/25
Filed: 1980-12-22
Abstract: To obtain an interference free connector between a signal transducer and a corresponding receiver the use of an optical cable is proposed. It also overcomes the problem of moisture penetration into an electrical cable. A typical application for the connector is in motor vehicles, for example for transmission of performance data to a microprocessor. The optical cable may be glass or synthetic and multi or single fibre (4), and is terminated at each end by a moulded on plug (S,E). At the transmitting end the plug body (11) contains a converter, for example a luminescent or laser diode (10), for changing an electrical into an optical signal. At the receiving end the plug body (15) also contains a converter, this comprising a photosensitive device (12), for example a phototransistor, an amplifier (13) and an impulse generator (14). At the transmitting end (S) the plug has two electrical contact pins (8). At the receiver end (E) there are normally three pins (9) in order to provide a power supply. Space can be saved at the receiver end by making detector (12) and amplifier (13) as an integrated circuit.

Title: Covering device for open containers of any desired filling
Inventor: MUELLER PAUL
IPC: E04H4/10
Filed: 1981-04-28
Abstract: Covering device for open containers of any desired filling, which is employed in container construction, electroplating or in the field of environmental protection, as well as in swimming-pool construction and storage-container construction, to prevent exhalation, evaporation, cooling or heating, and contamination of the container contents by means of sandwich films and other material. To ensure that no impractical raised parts occur around the container to be covered, the covering device is stationed such that it is sunk on or behind one container side. This covering device consists of a ground-level cover, on the underside of which is mounted a cantilever winding shaft by means of two lateral bearing plates. The cover is opened hydraulically, pneumatically or by means of a toothed rack and the like on one side of the container, in order that the flexible covering material wound on the winding shaft can be drawn, starting above the height level of the container contents and the container edge, onto the container or from it. The essential feature here is that the cover and the winding shaft form one unit and with the opening of the cover the shaft with the wound covering material reaches the corresponding height level. Hitherto, such covering devices have been arranged such that in the surrounding area of the container there were steps and, depending on the size of the container, the view of the container contents was impaired. Thus, a clear view into a swimming pool, laid down officially by the accident prevention regulations, was no longer guaranteed. In the technical sector such as in electroplating, transportation was no longer possible on one container side. In addition, the storage of other materials in other application areas was not possible on the covering side.

Title: Process for minimising waste gas temperatures in chimney installations and for improving draught conditions
Inventor: RODE WERNER ING GRAD
IPC: F23L17/16
Filed: 1981-05-09
Abstract: The invention relates to a process for controlling waste gas temperatures in chimneys and flue-gas ducts. For this purpose, there is built into the chimney a suction and acceleration section, consisting of an annular channel, for suction of the flue gases, and of, arranged in front of this, an acceleration nozzle, through which the flue gas is guided back into the chimney. A fan connected to the waste gas annular channel conveys the flue gas through a heat exchanger where it is cooled down. A measuring system optimises the heat recovery. As a result of the simultaneous acceleration of the waste gases in the chimney centre, the draught behaviour of the chimney is improved. Drawing "1" shows the system arrangement with the suction channel (1) and the acceleration nozzle (2). <IMAGE>

Title: Pick-up arm mechanism for a record player
Inventor: ADACHI KENGO
IPC: G11B3/085
Filed: 1981-06-16
Abstract: A pick-up arm lifting mechanism (50) with a lifter (2) is arranged in such a way that the pick-up arm (1) of the record player is raised and lowered. A magnet (16) serves as a drive, and there are provided a first swivel lever (9), which can be brought into contact with a section of the lifter, and a second swivel lever (14), which is driven by the armature (17) of the magnet. The second swivel lever is effectively connected to the first swivel lever by means of a flexible element, a helical spring (13), which prevents any impact from being passed on. Consequently, the linear motion of the magnet armature is converted into a rotational motion, in order to effect a gentle and slowed-down raising of the lifter. A viscous retarding material may be provided in the lifter in order to slow down the lowering motion of the lifter when the magnet is switched off. Part of the lifting mechanism may be designed as an electric switch (30) for sensing the raised position of the pick-up arm, while another part may be designed as a further switch for sensing the setting down of the needle onto the record. The information emitted by these switches may be fed to a control circuit, which influences the various operations of the pick-up arm, as a result of which the horizontal motion of the pick-up arm and the antiskating effect can be carried out accurately and precisely. <IMAGE>

Title: Suction box for the extraction of contaminated air which is produced during spraying of adhesive spray
Inventor: SCHAEFER GERHARD
IPC: B05B14/43
Filed: 1981-08-22
Abstract: With the use of spray adhesives, a fine adhesive mist is produced which does not remain completely adhered to the sprayed material. It is deposited in the close vicinity and soon covers the latter with a troublesome adhesive layer. The object was therefore to provide a suction box which completely extracts the adhesive-containing air, discharges the extracted air completely free of adhesives, is movable appropriate to the workplace and is economical in its energy consumption. The suction box presented here has been developed for processing spray adhesives. The switching on/switching off of the device is possible from any side via a foot switch and relay circuit. The material to be sprayed and the adhesive spray are processed within the spray/extraction cone which is open at the top and is made of low-reflection plastic. The contaminated air which is produced in the spray/extraction cone during use of the adhesive spray is transported via two large-surface-area filter levels, in the process is completely cleaned of solids and discharged back into the room. The unit can be used on rollers, appropriate to the workplace. <IMAGE>

Title: Method and arrangement for controlling and regulating the heating power of an electrical heating and/or drying apparatus
Inventor: BAROWSKI KARLHEINZ
IPC: G05D23/19
Filed: 1981-10-02
Abstract: The subject matter of the invention is a method and an arrangement for carrying out the method for controlling and regulating the heating power of an electrical heating and/or drying apparatus, especially an electrical hair-care apparatus. Both the series circuit of a first heating resistor (1) with a fan motor (7) and a rectifier circuit (6), as well as the series circuit of a second heating resistor (2) with a controllable electronic switch (5) and a control and regulation electronics device (4), are connected in parallel with an AC voltage source (U1, U2). The electronic switch (5) comprises a triac and an integrated zero-voltage switch, by means of which the heating power emitted by the second heating resistor (2) is reduced from the full value to zero. The reduction in the heating power is carried out by means of the control and regulating electronics device (4), which comprises a timer or RC element which commences at the start of power emission or commences with a delay. A possible delay is carried out by means of a timer (8) which controls the control and regulating electronics device (4). Both the commencement time of the heating power reduction and the gradient of the heating power reduction can be adjusted in steps or continuously. <IMAGE>

Title: Method for controlling the energy level, especially of the pi electrons, in water by means of a red-light laser in such a way that the water treated in this way can be used for preserving transplants
Inventor: BUDWIG GEB BUDWIG
IPC: C02F1/32
Filed: 1982-01-12
Abstract: Transplants, e.g. human organs, are stored in water. The present state of the art shows that decomposition of the tissue and disinfection are currently a problem. According to the document filed by me about the use of "heavy water", the problem of the toxicity of the bactericidal substances used to date has clearly not yet been solved. According to the invention filed by me it is now possible to solve the problem relatively well biologically in accordance with the natural laws about the function of the electrons in the water located within the hydrogen bonds as pi electrons, in resonance with the fields of the photons of red laser light. The feared decomposition of the tissue in transplants can only take place with the band shift from red to blue as far as U.V. Owing to absorption of introduced electromagnetic fields of the red light, which takes place in the pi electrons of the hydrogen bonds, the energy level in this medium, including the transplants, is pumped to a higher level. This counteracts the entropy in water and in the transplant. Since the nature and number of the microorganisms in their ability to germinate depends greatly on the electric and magnetic fields, this simultaneously makes "disinfection" by means of exogenous toxins unnecessary. The water according to this invention has been treated with red ruby laser in parallel beam or obtained as cooling water in laser irradiation. It is possible by direct irradiation of the glass vessels with transplants to charge the water including the transplants. Subsequent irradiation is recommended every 8 days since a decrease in energy naturally takes place.
