Title: Automobile engine fuel injection jet testing device - measures jet opening pressure by using sensor in muzzle to trigger sensor in fuel line
Inventor: KUNZFELD WILHELM
IPC: F02M65/00
Filed: 1980-12-12
Abstract: The device has a pressure sensor (14) in the fuel line (4) connected to the jet (6) for determining the fuel pressure for initiating opening. The jet outlet projects into the pressure chamber (12) of a muzzle (2) incorporating a second pressure sensor (16). The pressure chamber (12) has a restricted outlet channel (13), so that the required opening pressure is obtained from the signal provided by the sensor in the fuel line (4) at the point where a signal is first received from the sensor (16) in the muzzle (2). The device is used for routine testing of mfd. fuel injection valves before incorporating them in an engine.

Title: Paper making pressure roller - has swivel bearings at ends to allow bend adjustment
Inventor: SCHIEL CHRISTIAN
IPC: D21G1/00
Filed: 1980-12-24
Abstract: The mantle of the pressure roller with an adjustable bend, for paper manufacture, is supported at both ends by a swivel bearing at least, through the yoke (7). The hydraulic support mechanism within the roller mantle carries supporting forces from the yoke to the roller mantle. Both ends of the yoke have supporting surfaces resting on pedestals with the space between these surfaces along the vertical centre (m) being equal to or only marginally greater than the gap (I) between the bearings of the counter roller. The gap between the swivel bearings for the roller mantle is approximately equal to the space (I) between the counter roller bearings. A collar piece ranges from the pede pedestal within the roller mantle at each roller end for the yoke support surfaces. The design allows the bend to be applied at the ends of the roller, without increasing roller dimensions, so that the required pressures can be applied along the roller length. It also allows a drive to be fitted easily.

Title: Application of self-adhesive decorative coverings to the inner faces of roller shutters
Inventor: PURUCKER KLAUS
IPC: E06B9/165
Filed: 1981-11-12
Abstract: Self-adhesive decorative coatings are applied to the inner faces of closed roller shutters in front of windows and doors. The appearance of the roller shutters is thereby enhanced and they can be incorporated into the form of the window decorations. Fig. 1 shows closed roller-shutter sections (2) with glued-on decorative covering (1) in the form of plastic film, metal foil, artificial leather or decorative paper. The carrier material (3) used is insulating material to ensure thermally insulating and soundproofing properties when the roller shutter is in the closed state. The self-adhesive coating (6) ensures permanent adhesion to the roller-shutter sections. Prefabricated parting joints (4) are severed upon adhesion. The movements of the roller-shutter sections remain unimpeded. Stamped portions (5) are made along the parting joints (4) on either side. This material compression prevents water from penetrating and the decorative coverings from becoming detached from their base. Fig. 2 shows opened roller-shutter sections (2), provided with decorative covering (1), carrier material (3), self-adhesive coating (6), opened parting joints (4) and a stamped portion (5) on either side. The roller-shutter sections can be moved unimpeded. <IMAGE>

Title: Composite fabric as a covering for the sheet-forming region of a paper machine
Inventor: BOREL GEORG DIPL ING
IPC: D03D11/00
Filed: 1982-06-29
Abstract: A composite fabric serving as a paper-machine wire cloth consists of two fabric layers (1, 2) which each consist of interwoven structural longitudinal yarns (3, 4) and transverse yarns (5, 6) and which are connected to one another by means of binding transverse yarns (7). The structural transverse yarns (5) of the upper fabric layer (1) are also tied into the lower fabric layer (2), in order to connect the two fabric layers (1, 2) to one another as firmly as possible. At those locations where the structural transverse yarns (5) of the upper fabric layer (1) are woven into the lower fabric layer (2), the binding transverse yarns (7) are preferably tied into the upper fabric layer (1) and thereby replace the structural transverse yarns (5) at these locations, with the result that marking problems are avoided. <IMAGE>

Title: Composite slab laying carriage with controllable laying tongs
Inventor: AUMILLER RUDOLF
IPC: E01C19/52
Filed: 1982-07-24
Abstract: The additional application relates to a multi-wheeled laying carriage for composite concrete slabs, which are laid using a power drive with laying tongs. The way of achieving expert laying of individual composite concrete slabs was presented in the main application P 3133661.2. The additional application is a transfer to simple laying carriages. What is essential here is that the laying carriage carries with it a drive as motor or battery and this drive drives oil-hydraulics or an air motor. The oil pressure or air pressure is transferred via pressure hoses to cylinders or valves to the laying tongs. Controlling is performed by means of a hand lever or push buttons. When the laying unit is allowed out by the jaws of the laying tongs on the sand side, the laying unit is once again pushed back and made to enter the sand (see main application). Further claims are a compressed-air storage bottle, as energy dispenser, which is filled outside the laying carriage and is taken along in the laying carriage. The compressed air operates the laying tongs via hoses and valves. Further claims are some improvements of the laying carriage. <IMAGE>

Title: Roundabout with swinging passenger cabins
Inventor: PRZYBILLA HERBERT
IPC: A63G1/28
Filed: 1982-09-16
Abstract: The invention relates to a roundabout with a plurality of swinging passenger cabins which are suspended on extensions via freely swivellable cabin arms and which are moved outwards and upwards by centrifugal forces in dependence on the rotational movement and which are freely swivellable beyond the centrifugal position by means of power generators. The sequence of movement is determined by a momentum converter, whose curve follows a spiral and which consists of a momentum wheel and a momentum disc, forces produced by pneumatic cylinders acting both on the momentum wheel and on the momentum disc. The curve of the two movable converter parts is determined by the fact that the radius of the one rotating part becomes increasingly smaller and the radius of the other becomes increasingly larger. One of the two compressed air cylinders serves solely for compensating the torque determined by the deflection of the cabin. <IMAGE>

Title: Switched-mode power supply
Inventor: RADUCANU DAN CORNELIU
IPC: H02M3/156
Filed: 1982-11-11
Abstract: The invention relates to a switched-mode power supply, especially for the voltage supply of integrated components, having a regulated voltage with a ripple which can be predetermined. The switched-mode power supply has a longitudinal transistor whose base is driven via a further transistor, the base of the further transistor being acted on by a control circuit. The control circuit contains a comparator which compares the regulated output voltage with a reference voltage and opens or closes the further transistor and the longitudinal transistor in a pulsed manner, as a function of said comparison. Field-effect transistors are advantageously used as the transistors, it being possible to provide an additional oscillator in order to limit current surges on the input side, the output signals of which oscillator are linked to the signals emitted by the comparator in an AND or NAND gate and are supplied to the control connection of the further transistor.
