Title: Process for sintering green ceramic sheets
Inventor: LUBITZ KARL DR
IPC: C04B35/64
Filed: 1987-06-02
Abstract: In the sintering of stacks of green ceramic sheets, the separating agent (release agent) used is zirconium oxide whose particle diameters range over a plurality of orders of magnitude. The new process provides for the use of zirconium oxide particles whose particle diameter is the same as or slightly larger than the mean maximum peak-to-valley height of the surface of sintered ceramic sheet. In this way, only the zirconium oxide particles which are absolutely necessary for achieving the separability are used, the surface of the ceramic sheet is damaged less and the amounts used of zirconium oxide can be reduced overall. The zirconium oxide particles (2) are, prior to sintering, brought between each layer of the green ceramic sheets (1). The application can be carried out by dusting, spraying, printing, casting and tapecasting onto zirconium-containing support sheet. <IMAGE>

Patent DE-3727868-A1 (DE)
Title: Flat gasket made of soft material, particularly a cylinder head gasket
Inventor: MAJEWSKI KLAUS-PETER DIPL ING
IPC: F16J15/12
Filed: 1987-08-21
Abstract: In a flat gasket made of soft material, such as, in particular, a cylinder head gasket, with at least one metallically reinforced through opening, metal rings preferably consisting of beaded spring steel bear on one or both sides of the reinforced rim of the opening to increase the sealing pressure and they are connected positively or non-positively to the legs of the surround. By virtue of these measures, the rim of the opening is given special protection by the metallic surround and, by means of the bearing action of the metal rings, a particularly good sealing performance is achieved without the need for a larger installation space. There is thus no negative effect on the sealing performance of through openings arranged adjacent due to the design. <IMAGE>

Filed: 1987-12-22
Abstract: There is described a slay drive for a heavy loom, in which the slay (18) is driven by means of a toggle lever (2) from a complementary cam mechanism (3). The toggle lever (2) is in a folded-together position when the weaving reed (4) comes up against the fabric (impact point 15). The complementary cam mechanism (3) and the toggle lever (2) are preferably arranged underneath the slay support (1) to save space and to reduce the masses to be moved, the toggle lever (2) engaging on the slay support (1) below the centre of rotation (5) of the latter. Furthermore, a quick-acting shut-off device is provided, in that the arm (6) of the toggle lever (2) articulated on the slay support (1) is made foldable. During the weaving operation, the folding point (8) is so guided on a cam (9) that this arm (6) is in its virtually extended position. For the quick-acting shut-off of the slay drive, the folding point (8) is released or, as a result of the pivoting of the cam (9), is positively pressed away upwards, so that this arm (6) folds and force can no longer be transmitted to the slay support (1).

Title: Method and device for the stripping of thin wires insulated with high-temperature-resistant enamel
Inventor: PUTZ WILHELM
IPC: H02G1/12
Filed: 1988-02-26
Abstract: In the case of a known method of this type, through-passage stripping is used, with the wire being drawn through between adjustable rotating tools. According to the invention, the stripping of the thinnest wires is carried out by using abrasive bodies with a transverse extent as tools, these rotating in opposite directions each about one body axis, and by the wire executing a lateral movement between the abrasive bodies when it passes through the rotating tools. In the corresponding device, the tools are roller-type bodies (1, 2; 31, 32) which rotate in opposite directions about their longitudinal axes (I, II), the roller width (B) defining the maximum amplitude (b) of oscillation of the wire (10) passing through or of the wires (10, 20, 30) passing through. <IMAGE>

Title: Clamping device for clamping an elongated, linearly movable component
Inventor: EISTERT THEODOR DIPL ING
IPC: G05G5/22
Filed: 1988-04-11
Abstract: A clamping device for a piston rod (10) of a piston-cylinder arrangement comprises a clamping cylinder (12) in which a clamping piston (13) can be moved to and fro. The clamping cylinder (12) and the clamping piston (13) are passed through by the piston rod (10), the passage openings in the clamping piston (13) being an elongated hole (16). On one side of the clamping piston (13), pressure fluid is introduced and on the other side of the clamping piston (13) there is a compression spring arrangement (18). As long as the pressure in the pressure fluid is sufficiently large, the pressure can overcome the force of the spring arrangement (18); in the event of a pressure drop, e.g. a rapid pressure drop or a slow pressure drop caused by a leak, the force of the spring arrangement (18) overcomes the hydraulic pressure and displaces the clamping piston (13) against the outer surface of the piston rod (10). The device is used especially in hydraulic actuating devices in which secure fixing of the piston rod in a specific desired position must be ensured even in the case of a pressure drop or leakage. <IMAGE>

Title: Device for preparing cappuccino
Inventor: BORGMANN MICHAEL DIPL ING
IPC: A47J31/44
Filed: 1988-08-30
Abstract: The invention relates to a device for preparing cappuccino which can be used as an accessory device for an expresso machine equipped with a superheated-steam nozzle and can be coupled to the superheated-steam pipe of said machine. The superheated-steam nozzle is assigned an air-guiding device in such a way that the lower opening of the air-guiding device is arranged in front of the steam outlet opening for flushing around with superheated steam. The superheated-steam pipe has a hollow extension which is open towards the bottom and into which both the steam outlet opening and the lower opening of the air-guiding device lead. In this arrangement, a steam/air mixture is formed in the hollow space of the extension by sucking in air. This mixture can be led out through an outlet of the extension. To form a milk/steam/air mixture, the outlet of the extension is introduced into an external receptacle filled with milk. The upper opening of the air-guiding device is assigned a regulating device which influences the size of the opening cross-section. This regulating device is formed by the accessory device or by a part of the same. This is done in that the accessory device or one of its parts is detachably connected to the coupling of the superheated-steam pipe of the expresso machine. To form different opening cross-sections of the inlet of the air-guiding device, the parts are transferred into different positions, in particular angular positions.

Title: Sensor arrangement for spatial delimitation of the atmospheres in continuously operated industrial furnaces
Inventor: KLOEBER LOTHAR DIPL ING
IPC: F27B9/30
Filed: 1988-10-31
Abstract: The invention relates to a sensor arrangement for spatial delimitation of the atmospheres in continuously operated industrial furnaces, preferably in tunnel furnaces or continuous furnaces in the ceramics industry. The technical aim of the invention consists in developing a sensor arrangement for spatial delimitation of the atmospheres in continuously operated industrial furnaces which guarantees, irrespective of the changes in the atmospheres caused in terms of flow by the combustion and the car charge, a spatial delimitation, necessary for process management which is suitable for the quality, between oxidising and reducing atmospheres while observing the necessary process parameters, by selectively influencing the supply of the oxygen-containing carrier gas. According to the invention, the technical aim is achieved by known solids sensors being arranged in two cross-sections which spatially delimit the transition region between oxidising and reducing atmospheres. The cross-sections are in this case preferably arranged in the region of the burning zone.

Title: Method and arrangement for continuous location and guidance of a missile
Inventor: KARNING HEINRICH
IPC: G01S17/42
Filed: 1988-12-21
Abstract: Location and guidance methods for a missile which flies under the guidance of a control system, with a position sensor, at the other end of a laser-beam link. In order to enhance the interference immunity of the guidance data, the offset signals of the location system are produced by homodyne reception. Furthermore, the Doppler shift in the laser beam reflected by an on-board retroreflector is measured in order to determine the offset, the radiation emitted to the missile is passed via a scanning element (sampling element) before and after retroreflection, and the frequency and/or amplitude of the transmitted radiation is modulated in the control system. Finally, a portion of the laser transmitter radiation can be supplied via a polarisation filter and a phase retarder to a detector, and another portion can be supplied via a polarisation filter, a further phase retarder (which transforms polarised radiation) and expansion optics to the missile and from there, in the reverse direction, to the detector.
