Title: Overhead projector
IPC: G03B21/132
Filed: 1982-02-17
Abstract: In an overhead projector which consists of a housing having a transilluminated writing table, a projector arm pivoted to the housing such that it can be folded into a working position pointing obliquely upwards and into a transport position extending parallel to the writing table, and a projector head supporting the lens and deflecting mirror, the aim is to achieve the object of improving an overhead projector of the type mentioned at the beginning in the form of a portable appliance in such a way that in the transport position the overhead projector, which is equipped with a rectangular format of writing table, not only has a very low height, but also has a very short length. The invention achieves this object by arranging that the transilluminated writing table is square and that the projector arm can be telescoped to such a length that the projection head is situated directly next to the housing side averted from the joint of the projector arm or bears against it or projects into an inwardly directed bulge of this side wall.

Title: A process for the fixed-bed pressure gasification of lignite
Inventor: SCHOLZ GUENTER DR-ING
IPC: C10J3/16
Filed: 1982-02-26
Abstract: The invention relates to a process for the fixed-bed pressure gasification of raw lignite, in which, when higher water contents are used and higher throughput rates are realised, the features inherent to the basic principle of the process, such as an increase in the specific steam consumption and coal consumption, are compensated. A further object of the invention is to dispense with the pretreatment stages connected with the use of water-rich coals, such as, for example, drying and briquetting, whereby the process sequence is heavily burdened economically. The invention comprises compensating the known disadvantages of fixed-bed gasification, which result at high specific shaft loading, high water content of the feed coal, low cut height of the fixed bed and unduly small specific surface area of the grain mixture, by adaptation of the steam/oxygen ratio and thus applying the process principle in a field of use not hitherto exploited. The process is applicable to the manufacture of gas from coal for the most diverse fields of use, up to a pressure of 5 MPa.
Patent DE-3210340-A1 (DE)
Title: Device for indicating the position of a vehicle on a parking site
Inventor: WEINHOLD KARL DIPL ING
IPC: E04H6/42
Filed: 1982-03-20
Abstract: The invention relates to a device for indicating the position of a vehicle on a parking site, in particular in a garage. If the parking site is only relatively slightly longer than the vehicle to be parked itself, and if the aim is to avoid driving hard against the rear wall of the garage, it is difficult and also time-consuming to park in the site. In order to facilitate parking in the site in such cases, the invention proposes a device which is characterised in that it has a permanently mounted, compressible container filled with liquid, which is arranged at the level of the area of the vehicle which projects furthest, and that the interior of the container is connected in a communicating fashion to a display device which is attached so as to be visible to the driver of the vehicle and on which the liquid level can be read off. Because of the elasticity of the compressible container, not only is damage avoided, but a display which is visible is provided, for the driver of the vehicle which enables parking in the site to be very precise.

Free pistons, on which the initial excitation of some solenoids of the solenoid group (2) acts, and free pistons not so actuated are separated, and the needles corresponding to the free pistons not so actuated are pushed forwards as a result of the advance of the following housing (6) and by the movable stopper (10) thereby actuated. <IMAGE>
Patent DE-3218601-A1 (DE)
Title: Rotary-valve internal combustion engine
Inventor: GRASER MARTIN
IPC: F01C1/344
Filed: 1982-05-18
Abstract: The combination of a special shape of housing and a special sealing strip assembly with a specially constructed control part makes it possible to construct an internal combustion engine in which each component performs several functions. Despite this, its components are of striking simplicity and reduce manufacturing costs to a level far below those of conventional internal combustion engines. At the same time, levels of quality and efficiency are at least equal. If a compressor of the same type of construction is connected ahead of it, the internal combustion engine obtained is of the highest quality and the constructional outlay involved nevertheless remains low.

Patent DE-3233596-A1 (DE)
Title: Switch-on device for ignition systems of internal combustion engines
Inventor: KUGLER KARL-HEINZ
IPC: F02P9/00
Filed: 1982-09-10
Abstract: A switch-on device for ignition systems of internal combustion engines is proposed, a delay apparatus (18, 20, 31) serving for the delayed switching-on of the ignition system after actuation of the starting device (17) of the internal combustion engine. The delay time can be constant, dependent on the speed of revolution, temperature-dependent or dependent on the oil pressure. As a result, the initial phase of the starting process which is critical in terms of technical faults is bypassed and ignition misfirings which are caused either mechanically due to impact processes or electromagnetically due to voltage glitches on the vehicle electrical system are avoided. <IMAGE>
Patent DE-3237277-A1 (DE)
Title: Process for removing organic solvent residues from an aqueous washing bath
Inventor: FUEHRING HEINRICH
IPC: C02F9/00
Filed: 1982-10-08
Abstract: The invention relates to a process for removing organic solvents dissolved in an aqueous washing bath. Thorough removal of such solvents as far as an officially prescribed minimum value has not been possible hitherto even by stripping. In order to solve this problem, the invention provides that solvent-binding substances situated in the bath are initially precipitated out from the bath by addition of a sedimentation agent and that the residual solvent dissolved in the washing bath is then removed therefrom in a manner known per se by stripping. An additional improvement is achieved by filtering the bath after the precipitation and before the stripping.
Patent DE-3237995-A1 (DE)
Title: Electrical cigarette lighter
Inventor: ODA AKIRA
IPC: H01H37/76
Filed: 1982-10-13
Abstract: An electrical cigarette lighter, for example for a vehicle, has a circuit breaker in the form of an elongate fusible system which consists of a fusible element and a tube surrounding it. The melting point of the tube is slightly lower than that of the fusible element. If, in the event of the heating element arranged on the igniting part of the lighter becoming overheated, the fusible system melts and divides into two parts, the mutually separated ends of the fusible element are enveloped by the mutually separated ends of the tube. In this way a short circuit or flashover is prevented whenever the melted ends of the fusible system come into contact with adjacent parts of the lighter or other parts. <IMAGE>
Patent DE-3238592-A1 (DE)
Title: Device for the rotor-free agitation and pumping of liquids
Inventor: HEIMES HORST-PETER DR ING
IPC: F04B43/00
Filed: 1982-10-19
Abstract: The invention presented here of a device for the agitation and pumping of liquids in an open and closed chamber is based on the principle of transmitting the mechanical energy necessary for the agitation or pumping process through a diaphragm. This method has the advantage that the actual working chamber is free of mechanical elements of any type and can be fully encapsulated. Shaft through-leads and shaft seals or the like can also be dispensed with and the working chamber can to a great extent be designed freely so that, for example, no dead spaces of any kind are produced. Since the energy introduced into the working chamber is rotation energy, an hermetically sealed centrifugal pump in which the working liquid is not in contact with a rotor can be achieved by simple means.
Patent DE-3240707-A1 (DE)
Title: Circuit arrangement for monitoring electronic computing chips
Inventor: FISCHER WERNER
IPC: G06F11/00
Filed: 1982-11-04
Abstract: A circuit arrangement for monitoring electronic computing chips is proposed which output periodic signals at one of their outputs when operating correctly. To monitor the permitted minimum signal spacing of these periodic signals and the permitted maximum signal spacing of these periodic signals, a capacitor (14) having a continuously variable state of charge is provided which can be traced into a fixed state of charge in each case by the periodic signals (U10). The voltage surge at the capacitor (14) is then in each case transmitted to a second capacitor (23), the state of charge of which is again continuously variable. When a fixed voltage value (Us) is reached at the second capacitor (23), a reset signal (U28) is triggered. In this manner, signal spacings outside a predetermined time window are detected by means of a simple and inexpensive circuit and when these are detected, corresponding reset signals are generated for the computing chip (10). If the disturbance remains, new reset signals are continuously generated. <IMAGE>
Patent DE-3241813-A1 (DE)
Inventor: DOEMER JOSEF ING GRAD
IPC: H04L25/04
Filed: 1982-11-11
Abstract: The invention involves a self-adjusting equalizer configuration which automatically adjusts to the cable length. The equalizer configuration has band limitation for the transmission of digital signals and consists of an equalizing amplifier, a correction filter, and an amplitude control loop with a comparison of actual and nominal values. The object of the invention is to specify a circuit in which the correction filter is not located in the signal path. This object is achieved in such a way that the equalizing amplifier is located in the signal path, and the correction filter is placed in the amplitude control loop so that the output signal of this correction filter represents the actual value for the amplitude control loop.
Patent DE-3243012-A1 (DE)
Title: Method of producing oxygen
Inventor: HAGEL RAINER DIPL CHEM DR
IPC: C01B13/02
Filed: 1982-11-20
Abstract: The present invention relates to a method of producing oxygen from zinc peroxide. A zinc peroxide which is prepared both in known manner and in previously unknown manner by reaction of an ammoniacal solution of zinc salts with H2O2 is used. With this method of manufacture a zinc peroxide having at most 14% active oxygen is obtained. This oxygen is liberated either by heating the zinc peroxide or by reaction with acids or acid compounds, obtaining as intermediate stage hydrogen peroxide which is decomposed already in situ. The thermal decomposition can be effected either by external feeding of heat or by reacting the zinc peroxide with powdered metals which are mixed in the zinc peroxide. In this embodiment, the mixture of zinc peroxide and powdered metal need be ignited only at one point; once the reaction has been initiated, it then continues by itself. In the case of the decomposition of the zinc peroxide by acids or acid compounds, a decomposition catalyst for hydrogen peroxide is preferably mixed in the zinc peroxide.

Title: Method for setting a dimensionally accurate penetration path of the top tool of a bending press, in particular a folding press
Inventor: BRAND HEINRICH
IPC: B21D5/02
Filed: 1982-12-10
Abstract: The invention relates to a method for setting a dimensionally accurate penetration distance of the top tool of a bending press for bending sheet-metal workpieces in a bottom tool. After the first bending operation the top tool is relieved of load until it comes to rest under zero load on the workpiece. The relief path is measured as the bending open of the workpiece due to spring back and compared to a setpoint value for the dimensional accuracy. If the actual value deviates from the setpoint value, the top tool is driven back down by a penetration path corresponding at least to the relief path in order to bend the workpiece again, is relieved of load again until it comes to rest under zero load on the workpiece and so on until the required dimensional accuracy is achieved. The working stroke of the top tool is then set to the deepest penetration path. The penetration path is to this extent determined and set as it were automatically. <IMAGE>

Patent DE-3302649-A1 (DE)
Title: Heat exchanger
Inventor: LAING KARSTEN DIPL ING
IPC: F25B1/04
Filed: 1983-01-27
Abstract: Connected between the compressor and condenser of a heat pump, e.g. of a room air conditioner, is a heat exchanger which consists of spirally extending ribs(fins) (41) which feed the heat of the hot gas leaving the compressor to a partition (4) which carries ribs (11). A water current conveyed by the pump (17, 18) flows from the periphery to the centre, while the hot gas flows from the centre to the periphery. The ratio of the area of the heat-exchanging surfaces (41) to the area of the ribs (11) is as the ratio of the heat transfer coefficient of the water to the heat transfer coefficient of the hot gas. The housing (19) on the water side can be removed, so that the heat-dissipating surface of the partition (4) becomes accessible for removing scale. The partition (4) consists of two plates soldered together which enclose between themselves ducts (7) through which the working medium can flow off if a leak is produced in the partition. <IMAGE>
Patent DE-3304168-A1 (DE)
Title: Geared rotor engine
Inventor: WILDANGER ALFRED DIPL ING
IPC: F01C1/18
Filed: 1983-02-08
Abstract: The invention relates to a valveless combustion engine for liquid and gaseous fuels with continuous combustion and with only two intermeshing, contra-rotatable geared rotors (1) in a suitable housing (2) which is equipped with intake openings (3) and outlet openings (4), with a compression chamber (6) and a combustion chamber (7), and with known devices for fuel feed and control, ignition, cooling and lubrication, and which forms a suitable sliding seal for the geared rotors (1) on the lateral faces and on the gear rim peripheries. The geared rotors (1) are each rotatably mounted in this housing (2) by means of a shaft in such a way that at least one tooth of each rotor (1) engages with bilateral profile contact in the corresponding, opposing teeth of the other rotor (1) and a suitable cavity remains between the addendum of the one and the dedendum of the two other teeth. When the rotors (1) are rotating in the appropriate direction, fuel-air mixture is delivered from the intake openings (3) through the tooth interstices into the precompression chamber (6) and compressed, further compressed in the tooth interstices in the engagement area and fed into the combustion chamber (7) where combustion is brought about by means of an ignition device. By virtue of the magnitude of the difference of the tooth profile surfaces of the teeth moving towards the outlet openings compared to the incoming, partially overlapping teeth in the engagement area, the expansion pressure acts as a drive force on the rotors (1) and their shafts in the appropriaste direction of rotation, as a result of which further fresh gas is delivered, compressed and continually burnt. Owing to the virtually constant fresh gas delivery, compression and continuous combustion there is constant drive of the rotors (1) over a wide speed and output range. In Fig.1 the toothed rotor is represented in simplified cross-section without the other known devices. <IMAGE>
