Title: Internal combustion engine, especially reciprocating piston internal combustion engine, with compression space adjustable in operation
Inventor: WODICZKA ERNST
IPC: F02D15/04
Filed: 1986-04-16
Abstract: For an internal combustion engine, especially a reciprocating piston internal combustion engine 1 with compression space 10 adjustable in operation by means of a device 13, it is proposed that the device 13 be a wall section of a shape memory alloy, which, owing to its temperature-dependent deformation, automatically adjusts the compression space 10. For reversible deformation of the wall section 13 a reversing temperature is selected through the composition of the alloy in such a way that at low temperature when the internal combustion engine is at partial load a high compression ratio is set and at high temperature at full load a low compression ratio corresponding to the deformation. With the wall section 13 arranged opposite a recess 12 in the head 11 of a piston 9, both load-dependent, automatic control of the compression ratio and load-dependent, automatic adjustment of the combustion space geometry are achieved as a result of which an overall improvement of the engine efficiency and a reduction of the fuel consumption at partial load are obtained. <IMAGE>

Title: Casing for the thread-guide drum of a textile machine producing cross-wound bobbins
Inventor: BENDER HEINZ-GUENTHER
IPC: B65H54/72
Filed: 1986-10-31
Abstract: The casing of the thread-guide drum (2) consists of the casing parts (11) and (12) which form, approximately in front of the middle of the thread-guide drum (2), a wide-surface overlap (17) which, however, leaves a gap free for the passage of the thread. The casing parts (11) and (12) form upper thread-guide contours (22, 22') which guide the thread towards the middle at the start of winding, so that it can be intercepted more easily by the thread-guide groove (3) of the thread-guide drum (2). During the winding operation, the thread traverses underneath the overlap (17) on average along a traversing plane (7), its possibility of movement being restricted at all the critical points by lower thread-guide contours (23, 23'). <IMAGE>

Title: Method for computer-supported representation of test graphics to be investigated, in the form of dot matrix representations with two different target brightness values, by comparing with a stored pattern graphic
Inventor: PETERMANN HANS
IPC: G06T7/00
Filed: 1988-01-14
Abstract: A method is given for computer-supported representation of test graphics to be investigated, in the form of dot matrix representations with two different target brightness values, by comparing with a stored pattern graphic. For a specified section of the surface of the display device to be investigated, a specific binarisation threshold value is determined in each case, and the segments of the display device are correspondingly classified into "light" and "dark". To achieve a reliable evaluation, even if a respective display device to be investigated takes an arbitrary position within a tolerance range, and brightness inhomogeneities occur because of the illumination, for each such section the arithmetic mean of the currently greatest grey value of all stored pattern segments which may be within this section, taking position tolerances into account, and which are classified as dark, and of the correspondingly currently smallest grey value of the pattern segments which are classified as light, is used as the threshold value. <IMAGE>

Title: Use of power station residues as aggregate for mortar, in particular mining mortar
Inventor: RUF HEINZ DIPL PHYS DR
IPC: C04B18/02
Filed: 1988-02-05
Abstract: The invention relates to the use of power station residues such as flue-gas gypsum, fly ash and also products of the spray absorption and the dry-additive process, which are each compacted by themselves or in the form of a mixture and comminuted to the desired particle size, as aggregate for mortar, in particular mining mortar. In the use of such mortar, in the course of the pneumatic transport thereof, there is rapid breakup of the grain formed from the power station residue (mixture), which is a serious disadvantage (high dust formation, rising water demand, falling strengths, etc.). The object of the invention is to structure a grain produced by solidification of finely divided power station residues in such a way that its strength is substantially increased or its wear during pneumatic transport is substantially reduced. This is achieved by treating the compacted power station residues with hot steam.

Title: Water activation device
Inventor: STOG WILHELM DR
IPC: C02F3/10
Filed: 1988-02-09
Abstract: A device provided with an underwater support frame serves to regenerate wastewater by a contact section being arranged at a slight incline to the water surface. In this contact section, care is taken that the wastewater-air mixture delivered via the pump and the air supply unit can flow as slowly as possible with retention of air bubbles which are as small as possible in order to enable optimal contacting of the air bubbles with wastewater and the bacteria contained therein. Both the air bubbles and the bacteria can advantageously collect in the contact section and the latter can also grow and multiply, since the contact section is formed by a, preferably, Plexiglas tube which is filled with mesh spheres. These mesh spheres have a multiplicity of mesh rods which have a rough surface. Moreover, these mesh rods are arranged at a spacing which hinders the water flow as little as possible. This design results in a water activation device of short structure, the particular design, the mesh spheres and the transparent design of the tube significantly promoting the growth of the bacteria. <IMAGE>

IPC: B60K31/00
Filed: 1988-06-06
Abstract: A control centre transmits instructions to the vehicles at selected locations to limit their speed of travel to certain maximum values (Vz). In the vehicles it is verified whether the present speed of travel (Vi) exceeds the predetermined maximum speed. If this is the case, a control unit (R) in the vehicle causes the speed of travel (Vi) to be reduced to the predetermined maximum speed (Vz). The enforced braking commences only after a predetermined time delay (t2-t0), which allows the driver to brake his or her vehicle without the automatic system responding. <IMAGE>

Patent DE-3824038-A1 (DE)
Inventor: HARTMANN UWE
IPC: H04N9/29
Filed: 1988-07-15
Abstract: Circuit arrangements comprising a PTC resistor in series with the degaussing coil are known. The remainder of a current through the degaussing coil, remaining at the end of the degaussing process, is switched off with the aid of a relay. However, the abrupt switching-off causes a residual magnetic field which has a disturbing effect, particularly in large-size picture tubes. 
<??>A bridge rectifier arrangement is inserted with its alternating-voltage terminals into the circuit for the degaussing current. The direct-voltage terminals are connected to one another via a controllable electronic switch. A control circuit gradually drives the base current for the electronic switch down to the value zero. This provides for continuous degaussing.
