Title: Method for the production of fibre-reinforced metal
Inventor: HINO HARUMICHI
IPC: B22F3/26
Filed: 1988-08-25
Abstract: A method for the production of fibre-reinforced metal by distribution of reinforcing fibres in a metal matrix. For this purpose, a mixture consisting of reinforcing fibres, binder, thickener and water is first of all produced to give a fibre mixture. The fibre mixture is then introduced into a water-absorbent mould, the moulding surface of which is coated with a gelling agent for the fibre mixture, the fibre mixture thus being hardened by the removal of water. The water is absorbed in the water-absorbent mould. The fibre body formed in this way is then introduced into a casting mould. Molten metal is introduced into the casting mould in such a way that the shaped fibre body is impregnated with the molten metal. After solidification of the metal, the body is removed from the casting mould in the form of a fibre-reinforced metal in which the reinforcing fibres are uniformly distributed.

Title: Damping system for an offset printing machine
Inventor: AKAO YOSHIAKI
IPC: B41F7/26
Filed: 1988-09-24
Abstract: A damping system for an offset printing machine eliminates foreign particles on the printing surface to the greatest extent, prevents the occurrence of spots and ghosting, and improves the emulsification of the ink on the surface of the printing plate. The damping system comprises an applicator roller (6) which is driven by a motor (17) by means of a coupling (15). When the coupling is disengaged, the applicator roller (6) is driven by frictional contact with the plate cylinder (5) of the printing machine. A control circuit controls the rotary speed of the motor (17) corresponding to a speed command signal which is based on the circumferential speed of the plate cylinder (5), modified by a desired slip. The coupling (15) is engaged or disengaged in accordance with a signal which corresponds to the difference between the circumferential speed of the plate cylinder (5) and that of the applicator roller (6) and is transmitted by an electrical control circuit. The damping system furthermore comprises a motor circuit to actuate a multiplicity of motors for driving a dipping roller (2), the applicator roller (6), and the plate cylinder (5), and a control circuit to control the rotary speed of the applicator roller (6) with reference to calculations which are carried out on the basis of the rotary speed of the plate cylinder (5) and of a command signal which... by a speed command unit to the motor of the applicator roller (6)...

Abstract: A process for the edge and face grinding of cut blooms (1) to effect chip removal therefrom comprises measuring the bloom contours and coordinates, and the bloom feed speed and feeding distance remaining before it reaches the machining position are also determined. A grinding wheel (5) is adjusted in conformity with these measurement data, and the feed motions of the grinding wheel are controlled during bloom machining in conformity with the measurement data. In this way, the bloom can be passed through the grinding station and machined continuously. This facilitates the fully automatic grinding of edges and flame cut surfaces on longitudinally cut blooms. <IMAGE>

Title: Equipment chassis
Inventor: FEUERLEIN FRIEDRICH
IPC: H05K7/14
Filed: 1988-11-12
Abstract: It is intended to create an equipment chassis whose side walls can be produced from relatively thin profiled sheet metal (sheet-metal sections) and hold the front frame, which is manufactured as a plastic injection-moulded part, at the correct distance from the rear wall. It is intended to be able to use cylinder-headed bolts for connecting the parts without this causing any hindrance during installation of the equipment chassis into a housing, while at the same time making good utilisation of space. The side walls (12) are bent inwards at an angle of approximately 45@, like vanes, along their upper and lower edges so that bent strips (121) are produced. Bearing surfaces onto which the bent strips (121) can be placed are formed on those edges of the rear wall and of the front frame which extend in the insertion direction. The invention can be used for many equipment chassis which are provided for installation in housings, especially for switchboard equipment. <IMAGE>
Patent DE-3910165-A1 (DE)
Title: Adaptable component arrangement
Inventor: BADARAU TEODOR-JOHN DIPL ING
IPC: H05K1/00
Filed: 1989-03-29
Abstract: In electrical circuits, it is often necessary, in the test panel, to determine the optimum values of individual components and then to fit correspondingly matched components into the circuit. Because of the general ban on soldering in test panels and the danger of erroneous fitting, this working procedure often leads to faulty circuits, and automation of the component matching is possible only with comparatively high expenditure. According to the invention, an adaptable component arrangement is proposed, in which a set of components are connected to one another in the manner of a series or parallel circuit, with the component values being selected in powers of two. The components are connected to pins which are arranged in pairs, so that connection by short-circuiting connector is possible, and the individual components can thereby be switched on or off.

Date Aug. 22, 1991.A filter insert having a block-shaped configuration comprises a planar material that is permeable to a medium and is arranged as a plurality of pleats having pleat walls. Each pleat wall has opposing first and second edges. The pleat walls are arranged in a zigzag pattern presenting first and second edge sections wherein a medium to be filtered passes through the filter insert in a direction from the first edge section toward the second edge section. The pleat walls have embossed projections which are parallel to one another and project with a height in a direction toward an adjacent pleat wall. The projections have length in a direction from one edge to an opposite edge of a respective pleat wall and a width perpendicular to the length. The width is essentially constant over the length and the length exceeds the width. Adjacent projections of adjacent pleat walls contact one another for securing, spacing and stiffening the pleats and the filter insert. The first edges of every other pair of adjacent pleat walls and the second edges of a different every other pair of adjacent pleat walls are connected to one another by respective planar intermediate regions of the filter material at least in areas of the pleat walls exterior of the projections. The heights of the adjacent projections of the pairs of adjacent pleat walls connected at the first edge section increase in a direction toward the second edge section and the heights of the adjacent projections of the pairs of adjacent pleat walls connected at the second edge section increase in a direction toward the first edge section.

Title: Ring spinning machine - has surveillance devices on each traveller to detect broken ends or inefficient belt drive
Inventor: SAUERWEIN HEINRICH DIPL ING DR
IPC: D01H13/16
Filed: 1990-04-12
Abstract: A ringspinning frame has automatic surveillance of the travellers. Sensors on each unit send signals via a multiplex device. The analogue output is converted to digital, and transmitted to a central processing unit. The travellers along the frame (1n) are numbered according to the units on the frame. Each unit has a sensor (2n) which produces an analogue signal. The switch (3n) is activated at each unit in turn by the multiplexer (4). The analogue signal produced from each switch is converted to digital in the device (2). Because of the extremely rapid switching, interference patterns may be generated. These have to be filtered out (5) and the essential signal produced in square waveform (6) with an adequate signal over a period of time from each traveller. ADVANTAGE - The information received from each traveller in turn, not only demonstrates the presence of yarn, but the respective speed of yarn flow. This enables detection of a slipping drive-belt, with imperfect yarn prodn. at any partic. unit.
