Inventor: WEBER MANFRED DIPL ING DR
IPC: B22F7/06
Filed: 1992-02-19
Abstract: Sintered components consisting of at least two individual parts are produced by a process in which the component is pressed from powder, sintered, cooled and separated into its individual parts. Such a component may especially be a connecting rod with a divided big end for vehicle engines. It is the basic purpose of the invention to propose a process in which a high-grade product consisting of accurately fitting individual parts can be made with as few processing stages as possible. This purpose is achieved by the invention in that the component (16) has at least one separating slot (11) at the point of separation between two individual parts and, after cooling, is separated into its individual parts by breaking at the point of separation. The component (16) is preferably cooled immediately after emerging from the sintering furnace and then provided with at least one separating (11) or limiting slot (18) by mechanical machining. In an alternative embodiment the component (16) is partly cooled after sintering, calibrated, heat-treated and finally cooled.

Title: Stacking system for corrugated card panels - has two stacking positions operated in sequence for uninterrupted work-flow
Inventor: RUELKER THOMAS
IPC: B65H31/32
Filed: 1992-03-17
Abstract: The card sections are stacking into a programmed stack height under a feed system. When the stack is full the feed is directed to another stacking position upstream of the supply while the main stack is removed. When the main stacking position is empty the stacking resumes. The smaller stacks prepared in the alternative stacking position are moved to intermediate positions when a main stack is removed. Prior to restacking into the main stack the small stack is moved into place to start the main stack. In this way the supply of card sections is constant. USE/ADVANTAGE - Preparation of card sections for packaging. Constant stacking rate, maximum throughput rate.

Title: Vibration control for IC engine - monitors rate of change of engine speed and loading and corrects for changes by varying ignition timing
Inventor: KUGLER KARL-HEINZ
IPC: F02D45/00
Filed: 1992-07-08
Abstract: The control system monitors engine speed (n) and loading ( rho ) on the engine to provide rate of change of speed/load signals ( DELTA n/ DELTA  rho ). These are compared with programmed values in a range of programs to generate correction signals for the timing. For increases in loading the timing is retarded and vice versa for decreases in loading. The adjustment to the timing is progressive. The timing adjustment is in discrete steps to provide a smooth control. Changes in the throttle setting are taken into account in the derivation of the correction signals. An ignition timing counter provides a simple control. ADVANTAGE - Smoother running engine, simple correction control for ignition.

Title: Increasing wet strength of mouldings based on cellulose@ paper etc. - by impregnation with a soln. of oil-in-water emulsion contg. water-insol. (co)polymers, prepolymers, oligomers or monomers
Inventor: MUELLER-SCHULTE DETLEF DR
IPC: D21H21/20
Filed: 1992-07-17
Abstract: A process for increasing the wet strength of moulded or pressed prods. made of cellulose, paper, straw or derivs. thereof (I) comprises impregnation with a soln. of one or more water-insol. polymers, copolymers, oligomers, prepolymers or monomers (II) in organic solvent (III), or with an oil-in water emulsion contg. (II) dissolved in the organic phase. USE/ADVANTAGE - Impregnation with water-insol. polymer etc. renders the cellulose water-repellent and prevents penetration of water into moulded fibre composites etc. This greatly increases the wet strength of the prod. and considerably extends the range of application of such prods., e.g. as substitutes for plastic mouldings in the automobile industry. The process does not suffer from the disadvantages and high costs of prior-art resin-impregnation processes associated with the use of toxic and environmentally harmful chemicals such as formaldehyde and epichlorhydrin.

Light from the source is coupled into the polarising fibre so that both polarisation directions are equally strongly stimulated. The retarder is arranged in the light path between the polarising fibre and the sensor fibre, which is mirrored at its free end. The light produced by the source has a coherence length shorter than the optical path difference between the two optical axes in the polarising fibre. ADVANTAGE - Simplified construction.

Title: Appts for sputter coating substrates - using microwave resonator to improve coating
Inventor: BEISSWENGER SIEGFRIED DR
IPC: H01J37/34
Filed: 1992-11-27
Abstract: Appts for plasma sputter coating consists of a hollow resonator (28) into which microwave energy is fed; a chamber (3) in which a plasma is produced; a separation wall (15) between the resonator and chamber; a coupling device (24,27) which transfers the electromagnetic energy from the resonator into the chamber; and at least one set of permanent magnets (20,21) which creates a magnetic field in the chamber with a target (7) between them which is connected to the negative pole of an electrical DC source (72). The appts. has pref. several permanent magnets with targets between two magnets forming a pair. The coupling element (24) for the microwave energy is located between two targets. Each target has a holder (8,8") which is connected to the negative pole of the energy source and has a chamber for coolant flow. The field strength of the permanent magnets and the microwave source are adjusted so that an electron-cyclotron-resonance is produced. ADVANTAGE - Due to the combination of the antenna coupling and sputter magnetron, high plasma densities are created leading to high sputter rates. Very uniform coatings can be produced at relative low sputter voltages.

IPC: B63H11/08
Filed: 1993-02-20
Abstract: The subject matter of the invention is a water-jet propulsion device for ships which are intended for use in shallow waters. A semiaxially bladed rotor (3) with a vertical axis of rotation is rotatably arranged in a well-shaped housing (1). The drive (4) for the rotor (3) is inserted into the housing from above through a cover plate, and the housing is closed at the bottom by a base plate (6) which has a water inlet (7) arranged in the centre for the axial flow towards the rotor (3) and has at least one water outlet (8, 9, 10) inclined at a small angle. Arranged between the discharge end of the feed passages of the rotor (3) and the at least one water outlet is a distributor (5) in which the water delivered by the rotor (3) is fed to the at least one outlet nozzle without the conversion of flow energy into pressure energy. The distributor forms an annular passage without blading. The water inlet (7) is of asymmetrical design. The base plate with water inlet (7) integrated in it and the at least one water outlet (8-10) is endlessly rotatable about the longitudinal axis of the housing (1) in both peripheral directions, either as part of the housing, rotatable as a unit, or relative to the housing, which in the latter case can be part of the supporting structure of the ship. <IMAGE>

Title: Deformable mirror
Inventor: BAER KLAUS
IPC: G02B26/08
Filed: 1993-03-16
Abstract: A deformable mirror in accordance with German Patent 4138557 is given a particularly maintenance-friendly construction in conjunction with an extremely reproducible controllability of the curvature of its mirror surface (17) in that the individual parts of its translator (23) are clamped in, without a force-fitting or a positive connection, in a self-centring manner axially between an adjustable rear abutment (22) and the rear side of the mirror board (mirror plate) (13) as elastic abutment. The jam-free force transfer from the piezoelectric actuator (23) into the rear side of the mirror board (13) is ensured by a long sliding sleeve (21) between the open end, at the front side, of a casing tube (casing duct) (20) and a piston (21) which projects therefrom and in turn presses with its blunt, ball-shaped end surface (139) against a flat rear projection (118) of the mirror board (113). A hermetic, but flexible sealing is ensured between the front-side tube end (130) and the piston (21) emerging therefrom by a sleeve-shaped bellows (129) which at the same time can serve to seal the passage through a division wall (partition wall) (136) which subdivides the space behind the mirror board (13) into a decoupling space (135) statically filled with heat-transfer medium and a coolant space (134), separated therefrom in a pressure-resistant manner, for the purpose of heat dissipation by means of cooling medium (132) flowing through. <IMAGE>
