Title: Automatic winding of metallised or bare strips on core tubes - using swivelling rolls for pressing strips against core tube
Inventor: FETH JOSEF ING GRAD
IPC: H01G13/02
Filed: 1980-06-20

Title: Technique to determine max. deflection angle of coal excavator - using electrical signal produced by sensor in response to rotating field of transducer
Inventor: RADOSZ DIPL-EL-ING
IPC: G01C9/14
Filed: 1980-07-26
Abstract: A method and device for determining the direction of greatest inclination of an excavator are esp. applicable in brown coal mining. They enable continuous indication to be given to the driver for safety purposes. The rotation about a vertical shaft (6) of an arm (1) carrying a loading wt.

Title: Washing machine with vertical drum - operated by circulation of compressed air produced by impeller in lid
Inventor: KLOESTERS ALBERT
IPC: D06F17/12
Filed: 1980-11-13
Abstract: A top-loading washing machine with a vertical, rotating drum, which washes, rinses spins and tumble-dries, is operated solely by means of an air current circulated by an impeller mounted in the lid of the machine. The air passes along tubes around the outside of the drum and is inected into the liquor eccentrically from beneath the drum, thereby causing the drum to rotate, agitating the liquor and circulating the soiled articles within the liquor. The base of the machine incorporates a heater element. This is a more efficient process than that employed in conventional machines, requiring up to 60% less detergent, and only two hot rnses, giving considerable econoes in water, power consumption and in time.

Title: Back-up ring
Inventor: LUX FRANZ
IPC: B21D53/02
Filed: 1981-01-23
Abstract: With flat radiators made of sheet-metal half shells having connection pieces welded on by the pressure welding method, the half shells must be supported on one another at the welding point by a back-up ring. This back-up ring is located in the interior of the radiator and needs radial openings to allow through the heating water. These rings have hitherto been produced by turning and drilling. According to the invention, these rings are composed of two annular parts which are formed rather than machined, thereby reducing the expense involved in the production of this ring. <IMAGE>

Title: Sheet-holding system in sheet-conveying cylinders of sheet-fed printing machines
Inventor: RUDOLPH OTFRIED DIPL ING
IPC: B41F21/04

Abstract: The invention relates to a sheet-holding system in sheet-conveying cylinders of sheet-fed printing machines. The sheet-fed printing machines can be switched over selectively from face printing to perfecting and the sheet is turned by the principle of turning the trailing edge of the sheet. The object of providing a sheet-holding system which can receive the sheet at the trailing edge from a closed cylinder surface during perfecting and on which no conversion manipulations are required, in particular for the sheet rest when changing the mode of operation, is achieved in that the sheet rest of the sheet-holding system interacting with the suction device is arranged fixedly on the sheet-conveying cylinder in face printing and in perfecting. <IMAGE>

Title: Radial rolling-contact bearing with oil-bath lubrication
Inventor: FUEHRMANN JOERG DIPL ING
IPC: F16C33/66
Filed: 1981-04-15
Abstract: In the case of a radial rolling-contact bearing with oil-bath lubrication, in particular for the mounting of rotating drums, in the case of a rotating outer ring (3) problems occur since the oil is distributed due to the centrifugal force over the bearing periphery as a thin oil ring (28) and sufficient lubrication is hence not ensured. To avoid these shortcomings, use is made of the oil's static pressure occurring in the oil ring (28) to pass the said oil into a chamber (10) which is adjacent to the rolling-contact bearing and does not rotate, where it flows off downwards and provides the bearing with the required level. <IMAGE>

Title: Process and system for operating a platen press in the course of the production of chipboards, fibre boards and the like
IPC: B27N3/20
Filed: 1981-05-16
Abstract: The invention relates principally to a process for operating a platen press with one fixed press platen (2) and one press platen (3) moved by means of working cylinder/piston arrangements in the course of the production of chipboards, fibre boards and similar pressed boards. A mat (4) of material to be pressed is introduced into the open platen press and deposited on the fixed press platen (2). Then the moving press platen (3) is moved onto the mat (4) of material to be pressed by rapid traverse (S) as far as a changeover position (U), then at creep speed (s) until it makes contact with the mat (4) of material to be pressed and in order to build up the press-moulding pressure. In the process, the thickness (D) of each mat (4) of material to be pressed is measured, the changeover position (U) is set governed by the thickness (D) of the mat (4) of material to be pressed and then the rapid traverse is initiated which changes to the creep-speed traverse after the changeover position is reached. A minimisation of the time for closing the platen press is thus achieved without portions of material to be pressed being blown out by the air displaced during closing. The invention also relates to a system for carrying out the process described. <IMAGE>

Abstract: The invention relates to a tool for mounting locking clips on the end area of a pin or the like, in which a housing (2) has guide rails (7) spaced apart at its underside (2) for receiving the locking clip (10, 11). The housing (2), in its top wall located opposite the guide rails (7), has a recess (23) at one of its ends, one edge of which facing the one end forms a stop (17) for a lobe (13) projecting up at an angle from the top leg (10) of the locking clip (10, 11), and a bearing block (3) is fastened in the housing (2) in its other end area, which bearing block (3) has in the area of the guide rails (7) a bearing surface (8) for the area (14) of the locking clip (10, 11) in which the top leg (10) and the bottom leg (11) of the locking clip are connected to one another. In this arrangement, the distance between the bottom end of the stop (17) and the guide rails (7) is dimensioned in such a way that the locking clip can slide through under the stop (17) on the guide rails if the top leg (10) of the locking clip is not lifted beyond the spreading brought about by the guide rail (7) and that the lobe (13) of the top leg (10) of the locking clip acts on the stop (17) if the top leg of the locking clip, when being put onto the end area of the pin (32), is lifted beyond the spreading brought about by the guide rails (7). <IMAGE>

Title: Method and device for producing objects with a surface of second order
Inventor: KOBAYASHI HIROSHI
IPC: B24B13/015
Filed: 1981-06-25
Abstract: A working tool with a rectilinear working edge is fastened to a tool-holding arm which is arranged so as to be rotatable about a focussing shaft which extends parallel to a Z axis. The holding arm can slide rectilinearly parallel to an XY plane. A workpiece is fastened to a work holder in such a way that its centre axis runs in an X' direction which is inclined at an angle ( PI /2- THETA ) to the X-axis. The longitudinal direction of the working edge is inclined at an angle  THETA  with respect to a line which results from projection of a sliding direction of the holding arm. When the working tool and the workpiece are moved relative to one another, the workpiece is cut into a surface of second order, in accordance with a surface of second order which is formed by the working edge as an envelope of tangents.

Abstract: 1. Method for the non-destructive determination of the thickness of the iron-tin intermediate layer on electrolytically-tinned sheet steel by means of X-ray or gamma-ray radiation, wherein the radiation issuing from the sheet is measured on the same side of the sheet as the one which is irradiated, characterized in that, in the measurement, an energy is selected for the incident radiation which is higher than 7.111 keV which has a constant magnitude and the measuring is effected at an angle which lies between 6 to 20 degrees for the incident beam and for the beam issuing at the same side of the sheet, wherein the angle lies between the beam and the sheet surface or, with a curved surface, between the tangent and the beam, and moreover the measured values are taken simultaneously in the energydispersive mode from the fluorescence radiation of the iron and from one or more of the other enery regions of the diffracted beam, so that the measured values of the fluorescence radiation are representative of the thickness of the tin layer and the values of the iron-tin intermediate layer are computed from the other measured values with reference to the values for the thickness of the tin layer.
