Patent DE-3240224-A1 (DE)
Title: Piston for internal combustion engines
Inventor: DUERSCH VOLKER
IPC: F02F7/00
Filed: 1982-10-29
Abstract: The invention relates to a piston for internal combustion engines, having a top plate composed of a high-temperature-resistant material with low thermal conductivity and secured on the main body of the piston. In order to keep the mass of such a piston as low as possible while keeping the design as simple as possible, the join between the top plate and the main body of the piston is, according to the invention, of essentially spherical design, such that the top plate has a smaller height at the lateral surface of the piston or in the region of the ring zone of the piston than in the region of the piston axis. Between the top plate and the main body of the piston there is expediently a compensating layer composed of a material which reduces locally excessive pressures in the boundary layers of the two parts. <IMAGE>
Patent DE-3247722-A1 (DE)
Title: Polarographic pO2 test probe
Inventor: GRISARD KLAUS DR
IPC: G01N27/49
Filed: 1982-12-23
Abstract: A polarographic pO2 probe having a small active surface has, over the electrolyte space, an O2-permeable membrane which encloses the surface and is screened on its inner side from the electrolyte space in an O2-diffusion-tight manner, with one or more small holes being left free. In the vicinity of the holes, a large-area cathode is mounted on the membrane. The diffusion geometry consequently becomes independent of movements of the membrane, so that the probe becomes insensitive to mechanical disturbances or pressure disturbances.
Patent DE-3300908-A1 (DE)
Title: Marking system for cables and lines
Inventor: SCHAEFER HELMUT DR ING
IPC: H01B7/36
Filed: 1983-01-13
Abstract: For the clear functional marking, differentiation and grouping of electrical cables and of lines for electrical signals, for gases and fluids, according to the invention, tags are used which can be clipped on, may carry an inscription and - fitted together in various basic colours - form colour-combined tag groups which allow simple visual designation of the cables and lines. The marking tags may be connected to one another by means of brackets for uniform alignment of the tags themselves and, if required, their cables/lines. The marking system is supplemented by rings which can be clipped on and can be fitted together in the same way as the inscribed tags to form colour combinations. However, they differ therefrom in that they are not provided for an inscription. Instead, they carry information only by means of colours and, if required, by simple characters and symbols. They may therefore be of smaller and cheaper design, which favours their use in cable/line ducts. The marking rings may - as described - also be used for length marking of cables/lines. In addition, they support the reliability of the overall marking system, since their colour combination must be identical to that of the marking tags, and accidental incorrect fitment can thus be detected quickly.
Patent DE-3300945-A1 (DE)
Title: Ignition device for an internal combustion engine
Inventor: BREUSER ERICH DIPL ING
IPC: H01T13/54
Filed: 1983-01-13
Abstract: The ignition device (2) has an ignition chamber (21, 22) of rotationally symmetrical design, a first end of which lying in an axial direction is intended for immersion in a main combustion chamber (12) of an internal combustion engine. On the first end shot ducts (13) open into the ignition chamber (21, 22) so that a mixture of fuel and air forced out of the main combustion chamber (12) into the ignition chamber flows in the peripheral direction of the ignition chamber and also in the direction of the second end. An ignition spark gap (17) proceeding from a peripheral zone (16) of the ignition chamber is arranged between the two ends of the ignition chamber (21, 22). At different distances, which are shorter than the distance from the shot ducts (13) to the spark gap (17), connecting apertures (23) and passages (24) emanate from the ignition chamber (21). They connect this to a cavity (19) which receives fuel passing in the liquid state into the ignition chamber (21) following a cold start of the internal combustion engine and thus keeps it away from the ignition spark gap (17). In this way misfiring, which would otherwise occur when the internal combustion engine is not yet at full operating temperature, is prevented. <IMAGE>

Title: Process and device for controlling the profile of the quantity of plastic present before the first roll nip of a calender
Inventor: KUETTNER KEINZ DIPL PHYS DR
IPC: B29C43/24
Filed: 1983-01-29
Abstract: Plastic in the form of lumps (3, 8) or strips is fed batchwise to a calender via a transport belt (1), which is pivotable along the first roll nip. In order to control the quantity of the plastic distributed along the first roll nip, the height of the profile (24) over the roll nip is measured at fixed points along the filling nip (20). The measurements are subject to a filtering with limited memory. The filtered measurements, in relation to the sum of all measurements, as actual profile values of filling nip zones (A, B, C, D), are combined with predetermined setpoint values to form control deviation signals. The transversal movement of the transport belt (1) in the zones (A, B, C, D) is determined by the control deviation signals for the filling nip zones. <IMAGE>

Patent DE-3316229-A1 (DE)
Title: Device for preheating fluid fuel such as oil
Inventor: FUMAROLA JUN WILLIAM STEPHEN
IPC: F23D14/66
Filed: 1983-05-04
Abstract: A preheater is disclosed for fluid fuels which are pumped to a burner or an engine. The preheater is streamlined, and is, for example, a metal tube which is tapered at each end to a relatively small diameter in accordance with the size of the fuel line. The preheater is heated by an induction means or another heating means, which uniformly heats the fuel that has passed through the preheater to a temperature range between 70 DEG C and 300 DEG C. When fuel oil is pumped through the preheater according to the invention to a burner, for purposes of operational readiness the oil is heated in the preheater, with the fuel pump turned off, to a temperature which is close to the flashpoint, but below it. The oil is heated in the preheater to a temperature above the flashpoint when the fuel pump and the burner are operating. The preheater according to the invention renders heavy liquid oils more capable of flowing and burning, and leads to a general improvement in the combustion efficiency of various fluid fuels.

Title: Walking mechanism for hydraulic support assemblies, in particular shield-type support assemblies
Inventor: LAGODKA GUENTER
IPC: E21D23/08
Filed: 1983-05-17
Abstract: The invention relates to a walking mechanism which is arranged between the floor skids of a shield-type support assembly or the like and has a walking cylinder which is mounted in a guide frame and the piston rod of which is connected via a guide linkage to the walking abutment (face conveyor). At the rear end, the guide frame is attached via an articulated connection to a cross piece which lies in the intermediate space between the two floor skids and is connected here to the floor skids. The length of the cross piece is not greater than the lateral distance between the floor skids. The guide linkage conveniently consists of two parallel elastic guide rods which lie below the guide frame and are guided on it so that a small overall width of the walking mechanism is obtained. The connection head connecting the piston rod of the walking cylinder to the guide linkage is conveniently arranged in such a way that it can be shifted on the guide linkage, as a result of which the distance of the support assembly from the working face can be set.

The stop can be set via the setting scale to the corresponding width of the spar of the sectional frame to be machined against the spar rear side opposite the cross-spar.
Patent DE-3325560-A1 (DE)
Title: Adjustment (throttling) on four-stroke engines, in order to save fuel
Inventor: MAMIC ZDRAVKO
IPC: F02B75/02
Filed: 1983-07-15
Abstract: The compression space is reduced in comparison to known engines and the closing of the intake valve is somewhat retarded to the same extent. The compression ratio remains unchanged. By means of this measure the mean working pressure is reduced and there is a reduction in power, but the "power:fuel consumption" ratio is more favourable than hitherto, which is precisely the aim of the invention. In the novel design, the ignition timing is somewhat retarded so that ignition occurs somewhat later than in known engines. This results in addition in a lighter engine construction.

Title: Rise-heading transporter
Inventor: FARKAS LASSLO TIBOR DR ING
IPC: E21F13/00
Filed: 1983-08-27
Abstract: A transport vehicle which consists of a caterpillar truck of low overall height and a drive unit and load-lifting means leading or trailing in the direction of travel serves to produce rise and dip headings in coal mining and also to prepare longwall faces. The caterpillar truck is connected to the drive unit on the one side and to the load-lifting means on the other side via a double articulated joint so that the transport vehicle can readily adapt to upgrade transitions occurring at adequate ground clearance and also has optimum curve-going capacity. The transport vehicle does not depend on rails and in addition can be operated without supply cables, because the drive unit has a battery which at the same time provides for the requisite counterweight for the load-lifting means. <IMAGE>
Patent DE-3331631-A1 (DE)
Title: Semiconductor component
Inventor: INOUE KEIJI
IPC: H01L29/73
Filed: 1983-09-01
Abstract: In a semiconductor component in which a freewheeling diode is formed immediately underneath a terminal solder joint, the diode is insulated from the base region of a power transistor formed at the same time so that no interaction can occur. As a result the freewheeling diode can be incorporated without extending the chip area, and the resistance of the transistor to damage or destruction is increased. The thickness of the main electrode layer of the diode, which uses the same semiconductor layer as the transistor, can be made less than the collector layer of the transistor. Consequently, the surface area required for the diode can be reduced while achieving the same withstand voltage of the transistor and diode, which facilitates miniaturisation of the semiconductor component. <IMAGE>
