Title: Process and apparatus for the precision grinding of screen printing squeegees
Inventor: KUERTEN RUDOLF AUGUST
IPC: B24B1/00
Filed: 1986-04-30
Abstract: In this process the two sides of the working edge of a screen printing squeegee, which at least at this point consists of a soft/resilient material, are no longer ground on the limiting surfaces as before with abrasive paper but high-speed carbide milling cutters. In this case, both surfaces can be ground simultaneously by the use of two milling machines. It is also possible to perform rough grinding and finish-grinding in one operation, again by using two milling machines.
Patent DE-3617282-A1 (DE)
Inventor: STEINMANN DETLEF DIPL ING DR
IPC: C04B35/58
Filed: 1986-05-23
Abstract: Polycrystalline sintered bodies are provided consisting of at least 66% by weight of a crystalline Si3N4 phase, of which at least 90% by weight is in the beta-modification, and of up to 34% by weight of secondary intergranular grain boundary phases of oxide, carbide and/or nitride. At least 25% by weight of the secondary grain boundary phases consists of a quasi-ternary crystalline compound in the E1-E2-E3 triangle of the Ga2O3-La2O3-Al2O3 ternary system called "Gala", the "Gala" compound being prepared from gallium oxide, lanthanum oxide and aluminum oxide prior to producing the sintered bodies. The polycrystalline sintered bodies are produced by sintering with and without application of pressure from silicon nitride powders having a portion of impurities not exceeding 4.0% by weight, sintering additives of oxides and optionally other refractory admixtures of carbides and/or nitrides. Powders of a quasi-ternary crystalline compound (Gala compound) are employed as at least one sintering additive prepared, prior to mixing with the remaining components and to sintering, from gallium oxide, lanthanum oxide and aluminum oxide by heating to temperatures from 1500 DEG  C. to 1850 DEG  C. When using at least 70% by weight of silicon nitride powder, there can be used up to 30% by weight of a crystalline "Gala" compound alone or mixed with other admixtures of oxides, carbides or nitrides, but altogether at least 1% by weight of a crystalline "Gala" compound must be present. The sintered bodies are especially tough and very hard and can be used for the machining of iron materials at high cutting speeds.

Patent DE-3632705-A1 (DE)
Title: Set of forms or paper for office machines
Inventor: BEHRENS HERBERT
IPC: B41L1/22
Filed: 1986-09-26
Abstract: When using sets of forms or paper in office machines, it is a requirement that the individual original sheets (1) or end sheets (3) are not displaced in relation to the carbon sheet (2). In order to prevent this happening, it is known to connect the carbon sheets to the bottom sheet via a lateral adhesive edge. Since the adhesive effect of these adhesive edges is reduced very quickly in the known carbon sheets, the carbon sheets have to be thrown away although they have not yet been used up. These disadvantages are avoided according to the invention in that the carbon papers or the papers producing the copies have self-adhesive adhering surfaces of adhesion glue as adhering edges at their leading edges which pass through the printing station first. These adhering edges exhibiting adhesion glue guarantee a reliable bonding to the original sheets and the end sheets over a prolonged period. It is thus possible to use the carbon papers until they have been used up completely. Due to the fact that the adhering edges consist of self-adhesive partial zones which are not connected to one another and are arranged offset alternately on both sides of the carbon papers, the carbon sheets can easily be removed from a pile in printers with an automatic feed. <IMAGE>

Patent DE-3701165-A1 (DE)
Title: Mounting bracket
Inventor: AUWAERTER RUDOLF
IPC: B60D1/14
Filed: 1987-01-16
Abstract: Various demands are made on the connection between the drawbar tube and the front transverse part of the trailer. On the one hand, the intention is that all of the moments of load occurring at this point, including adequate reserves, can be absorbed, on the other hand, the intention is that this connection be releasable, that it likewise have a low dead weight and that it be cheap to produce. By virtue of the shaping of the mounting bracket all requirements are achieved in that the mounting bracket can be cut out of sheet metal using a maximum of just five cuts, 3 holes for the bolted fastening are punched in and two ends, which taper to a point, are bent off at right angles. The angled-off, short ends are welded onto the drawbar tube longitudinally with respect to the direction of travel. The flat, long legs which thus protrude at right angles to the drawbar tube and taper to a blunt point are bolted such that they lie flat by means of bolts to the front transverse part of the trailer. The course of the forces along this connection runs with respect to the drawbar tube into the vertical leg of the front transverse part and is distributed in each case to the right and left outwards to the main side members.
Patent DE-3702015-A1 (DE)
Title: Surgical suturing machine
IPC: A61B17/04
Filed: 1987-01-24
Abstract: The surgical suturing machine comprises a housing (10) on whose head piece (14) there are releasably located a needle holder (16) holding a needle (30), a thread catch (18), a rotatable cylindrical body (20), a stationary foot with a plate (70) and a smoothing mechanism (22). The projecting tissue edges to be sutured are clamped between the plate (70) and the cylindrical body (26). During movement of the surgical suturing machine the profiled circumferential surface (78) of the cylindrical body (20) rolls over the outer side of one tissue edge. The circumferential surface (78) of the rotating cylindrical body "grips" the external surface of one tissue edge and guides the two tissue edges toward a clamping zone located in the region of the shortest distance between the plate (70) and the circumference (78) of the cylindrical body (20). The projecting tissue edges are pierced by the needle (30) in the clamping zone and sutured by means of the thread catch (18) and the needle (30). Thereafter, they are flattened by the smoothing mechanism (22), so that the edges of the tissue edges oppose each other in a manner bluntly abutting each other. In a second embodiment, there is an air suction holding device (24) for the tissue edges, which is effective during each suture forming operation, in the suture forming region of the needle (203), which device can be moved up and down in a vertical plane by a drive mechanism (236-239). <IMAGE>

Inventor: BLAUHUT REINHOLD
IPC: F42C11/00
Filed: 1987-02-25
Abstract: Device for target identification and fuze triggering of horizontal mines which are to be fired for anti-tank purposes in a target zone. Two directional microphones which are sensitive to armoured vehicle noise as well as a seismic sensor which is sensitive to seismic waves characteristic of armoured vehicles and an electronic evaluation device are provided. The receiving lines of the directional microphones are directed at the target zone and are at an acute angle with respect to one another, which angle encloses the firing direction of the horizontal mine. The evaluation device initially interrogates the seismic sensor for seismic waves which are characteristic of armoured vehicles, and activates the directional microphones in the event of seismic waves which are characteristic of armoured vehicles. The evaluation device detects the sound waves received by the two directional microphones and/or the received sound energy separately, the phase shift is determined, and fuze triggering is activated when the phase shift is at a minimum. <IMAGE>

Title: Rotation device on a launched (ejected) munition
Inventor: GUNDEL BERND
IPC: F42B10/56
Filed: 1987-06-25
Abstract: A rotation device (16) on a launched munition (11) which falls into a target area braked by a parachute (12), such as, in particular, a submunition (11) with a search fuze, which searches especially the target area while falling in a spiral shape, looking for a target object to be engaged, is intended to be implemented with a small structure and in a structurally simple manner, said implementation allowing design specifications for the rotational movement kinematics within wide limits. For this purpose, the cable (20) by means of which the munition (11) is supported by the parachute (12) is designed to unreel a length of cable from a spool former (22) constructed in the munition structure (23), with a hinge point (24) of the cable (20) pulled off the spool former (22), which hinge point is located eccentrically with respect to the munition axis (15) and rotates in a cross-sectional plane of said munition structure (23). The radial position of the hinge point (24) determines the inclination of the munition axis (14) with respect to the vertical (15), and the support of the hinge point (24) against the friction rotating arm (27) determines the magnitude of the tumbling-rotating movement of the munition (11). The movement of the rotating arm (27) relative to the munition structure (23) can at the same time be used for generating dynamo-electrical energy, as a consequence of the cable (20) unreeling. <IMAGE>

Title: Batches for glassmaking, and process for the preparation thereof
Inventor: PIEPER HELMUT DIPL ING
IPC: C03C1/00
Filed: 1987-08-12
Abstract: Batches for glassmaking comprise principally quartz, soda and calcium carbonate. Of the batch constituents, soda represents the largest cost factor. The novel batch is intended to be significantly less expensive. In the novel batch, at least some of the soda is replaced by sodium hydroxide solution in a concentration of from 10 to 30% by weight of sodium hydroxide in water. Such sodium hydroxide solution is formed in plastics production as a waste product which has hitherto been dumped. In order to prepare the new batch, the dry constituents of the batch are premixed, and the sodium hydroxide solution is added just before the batch is introduced into a glass melting furnace. The novel batch is suitable for the production of conventional glasses, for example for bottles or window panes.
