Title: Process for the production of engine parts capable of high loading, particularly internal combustion engine parts
Inventor: SOMMER RICHARD
IPC: F02B77/02
Filed: 1982-04-02
Abstract: In a process for the production of engine parts capable of high loading, particularly internal combustion engine parts, with a tough, high-strength core and a skin which is still hard and highly wear-resistant and corrosion-resistant even at high operating temperatures, the engine parts are produced from a steel which has, as a carbide and carbonitride former, vanadium with an alloying proportion up to about 0.3 per cent by weight. The engine parts produced from this steel are subjected to a boron treatment process with a process temperature above the conversion temperature of the basic material in the  gamma -phase of about 860-1000 DEG C; during the duration of this process, on the one hand the vanadium goes into solution in the basic material which is in the  gamma -phase and on the other hand the boron diffusing into the surface of the engine parts forms a Fe2B skin up to several tenths of a millimetre thick. The engine parts are thereafter subjected to a cooling process which takes place at a cooling rate of about 2-50 DEG C per minute, resulting in a fine-grained structure in the basic material and also precipitation hardening with a consequently high-strength, tough engine part core. Engine parts produced according to this process are very vibration-resistant because of their high-strength, tough core, and apart from this, because of their borided skin with a hardness of about 2000 HV at room temperature, are also highly wear-resistant and corrosion-resistant, even at severely elevated temperatures.

Title: Rear ventilation arrangement
Inventor: PFEIFER JOHANN B
IPC: F24D11/02
Filed: 1982-05-24
Abstract: Rear ventilation arrangement for exterior surfaces (1) of buildings, with a lining (4 or 6) spaced from them, the exterior surface being provided with a layer of insulating material (2 or 7), between which and the lining (4 or 6) an air channel (11 or 12; 23, 23' or 22, 22') is formed, in which the evaporator (5 or 8, 9 or 25, 26) of a heat pump is located. For optimum extraction of heat from the atmospheric air, the air channel (11 or 12; 23, 23' or 22, 22') is connected to the external atmosphere via an air inlet (3; 16; 20) and air outlet (29, 29' or 30). The evaporator (5 or 8, 9) is preferably arranged immediately before or in the air outlet, in particular when a finned evaporator is concerned. If the evaporator is formed by spaced-apart evaporator tubes (25), this evaporator extends substantially through the whole air channel. The air inlets and outlets are respectively arranged such that they are protected from the weather. Reliable operation is thus ensured even in snowy or icing conditions, etc. <IMAGE>

Patent DE-3229756-A1 (DE)
Inventor: VOEHRINGER GERHARD FRIEDRICH
IPC: B05B14/48
Filed: 1982-08-10
Abstract: A powder spray booth wherein the workpieces are moved through a coating space and coated by powder coming from an electrostatic spray gun at a spray opening. An aspiration blower is used for forcing the air coming in through the spray opening through a cyclone unit with a battery of cyclone separators and through a filter unit with a filter bag. The air is moved upwards along upwards sloping lines of flow to the aspiration duct, and the powder is moved downwardly under the effect of gravity. Only a part of the powder reaches the cyclone separators and is removed from them through airlocks. The part of the powder not separated in this way deposits in the filter space, a part of it only after cleaning the filter. This part of the powder is removed on opening an outlet door and is taken up on the screen of the powder car and then mixed with the powder from the cyclone separators or, by opening the outlet door, run into a space, where a second powder car may be placed. By designing the cyclone units as part of the booth or booths the overall structure is made simpler and the time needed for cleaning down on changing the color of the powder is decreased.
Patent DE-3233099-A1 (DE)
Title: Feeding station for feeding pourable conveying material into the pipe of a pneumatic conveyor system by means of compressed air
Inventor: KRAMER KARLHEINZ
IPC: B65G53/36
Filed: 1982-09-07
Abstract: The invention comprises two feeding containers which are set for intermittent compressed air pressure and are connected to the same pipe by means of branch sockets. A control device for a separate flow of compressed air is connected to both branch sockets. A separate compressed air line leads from the control device to the pipe. The control device is transferred from open to closed position for the flow of compressed air by the flows of conveyed material intermittently exerting pressure on the two branch sockets, and automatically returns to the open position in the intervals when there is no flow of conveyed material, with the constantly present compressed air being released as an additional carrying medium for the conveyed material as it flows into the pipe. In this way, a continuous flow of conveyed material is achieved even when the feeding station operates in a discontinuous manner. The conveying power is reduced and the danger of blockages avoided as a result of this. <IMAGE>
Patent DE-3233243-A1 (DE)
Title: Motor and accessories, especially coal-fuelled motor
Inventor: EICKMANN KARL
IPC: F02B1/04
Filed: 1982-09-08
Abstract: The invention relates especially to means for making the pressure and the temperature in the external combustion chamber of a combustion space fed by a compressor set so high between compressors and decompressors, while keeping the whole motor or the combustion plant safe in operation, that at the high temperature even solid fuel, for example in rod form, can be combusted with a given pushing speed of the fuel rod. The temperature can be raised sufficiently for the fuel rod being pushed in to ignite spontaneously and to burn. Gas which is too hot after the combustion may be efficiently cooled by spraying in water and used for the performance of work. In carrying out the invention it was found that such motors with external combustion chambers can also operate, because of good compressors, valves and design of the combustion space, as petrol engines with degrees of efficiencies, not inferior to those of conventional spark-ignition engines. Fuel powder can also be combusted and the parts for completion of the motor can find further applications in hydraulics and pneumatics and also in aircraft construction and in the vertical take-off of fixed wing aircraft. Because the decompressors in such motors give out work in each downward stroke, the motors are especially compact or they give increased power per weight and dimensions.

Title: Head switching circuit for a video signal replay device
Inventor: IWAFUNE KASUKE
IPC: G11B5/55
Filed: 1982-09-15
Abstract: A head switching circuit for a video signal replay device effects the switching-over of a normal and of a special replay head for scanning a helical-track magnetic tape which can be switched to a different speed than with a normal-replay operating mode for a special-replay operating mode. To reduce picture disturbances during the operating-mode switching, the head switching circuit contains a normal-speed detector circuit (20) generating a normal-speed detection signal when the normal tape speed is reached during the operating-mode switching; a system control circuit (19) which generates a normal- or special-replay operating-mode signal during the operating-mode switching, and a head switching control circuit (21) which, during the operating-mode switching from a higher special replay tape speed, keeps the tape scanning switched to the special replay head (18a, 18b) until the normal-replay operating-mode signal and the normal speed detection signal are generated at the same time, and then switches the scanning to the normal replay head (17a, 17b). <IMAGE>

Title: Process for optimising and producing ordered axial HGMS filters
Inventor: GREINER HORST
IPC: B03C1/034
Filed: 1983-02-14
Abstract: The invention relates to a method for optimising the geometry of so-called axial HGMS filters (high gradient magnetic separation) with respect to their efficiency and a corresponding construction process for such filters. In an axial HGMS filter, weakly magnetic particles suspended in a liquid flow parallel to thin ferromagnetic wires which are magnetised in an external magnetic field applied perpendicularly to them. As a result of the high magnetic field gradients resulting in the vicinity of the wires, the particles are deposited on the wires and a separation of particles and liquid is thus achieved. The invention provides a method for discovering the most optimal arrangement of the wires with regard to filter efficiency. For a given space filling of the filter volume by the wires, the optimal arrangement of the wires is given. A production process is also described for correspondingly optimised filter matrices.

IPC: E04C2/34
Filed: 1983-03-04
Abstract: Profiled building element made of plastic material for walls and roofs and subdivided into longitudinally directed parallel channels, partly by curved partition walls (3 and 4) running transversely to the longitudinal axis, which partition walls are joined and act as beams between the two walls (1 and 2) which form the outside and inside of the element, and partly by an intermediate wall (7) lying between the outer wall (1) and inner wall (2). The transversely running partition walls (3 and 4) are curved, with the curves alternately facing one another and opposing one another. The partition walls (3, 4) can, in pairs, have the shape of joined-together circular cylinders which are tangent to the outer wall and inner wall or project beyond these. The partition walls (3 and 4) can additionally be joined to the outer wall and inner wall at a mutual distance and can be cylindrical surfaces of any desired suitable shape. The partition walls (3, 4) are attached in each profiled element in such a way that, on connecting two or more profiled elements by means of assembly members (5, 6) along the lateral edges, they continue in the same sequence from element to element with alternate curvature to one side and the other, and possibly in pairs if each partition wall (3 and 4) is constructed as a double beam. <IMAGE>

Title: Drive control device for a motor vehicle
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: B60T13/68
Filed: 1983-05-26
Abstract: A drive control device for a motor vehicle with rear axle drive is described, which for each driven rear wheel comprises an auxiliary brake, by admission of the correct control brake pressure to which the respective drive wheel tending to spin is slowed down. The auxiliary brakes are designed as low pressure disc brakes which are incorporated into the housing of the differential gear. They are capable of being acted upon by the outlet pressure of the engine oil pump by way of an electro-hydraulic control element which can be triggered by output signals of an electronic control unit responding to the dynamic behaviour of the driven vehicle wheels. The control device can be switched on and off selectively. When it is switched on the auxiliary brakes are subjected to a basic pressure, by means of which the idle movement in an axial direction of displaceably arranged rotor and stator plates is compensated for and a rapid response behaviour of the drive control device is obtained.
