Patent number: 5118242Abstract: In a loading system for containers, tank vehicles, or other containers that can be flange-mounted to the discharge hopper of a silo, with a tube slide, the inner casing of a double-walled dump pipe that is secured to the discharge hopper is used as a guide for this tube slide. The loading system is arranged beneath this discharge hopper. Apart from the closed position and the dump position, the tube slide can also be locked in a flushing position by means of an operating system. The lower end of the tube slide is configured as an opener for a closing plate of the filler opening of the container or the like that can be closed by the action of a spring.Type: GrantFiled: August 6, 1990Date of Patent: June 2, 1992Assignee: Innoplan-Ingenieurgesellschaft Braas und Co. mbHInventors: Helmut Ebert, Edmund Heschek

Patent number: 5118214Abstract: The invention relates to a connecting assembly for use in the propeller shaft in the driveline of a motor vehicle between the end of a tubular shaft, especially made of a composite material, and a connecting piece positioned coaxially relative to the shaft end. The shaft and connecting piece have connecting structures which inter-fit in the circumferential direction. The tubular shaft is designed to sustain without damage greater impacting force in the longitudinal axial direction than is required to displace the connecting piece relative to the shaft in this direction.Type: GrantFiled: June 25, 1990Date of Patent: June 2, 1992Assignee: GKN Automotive AGInventors: Miloslav Petrzelka, Werner Hoffman

Patent number: 5116423Abstract: The present invention relates to a method and an apparatus for washing pulp according to which method the pulp is supplied onto a movable liquid-pervious support surface to form a substantially continuous layer; and washing liquid is supplied to the pulp layer and passed in several successive washing phases through different areas of the layer in such a way that the washing liquid gradually flows in the opposite direction compared with the flow direction of the pulp layer. According to the invention the washing liquid is divided in two or more partial flows which pass alternately through different washing phases in such a way that the washing liquid which in one phase has passed through the pulp layer flows past at least the washing phase preceding it in the flow direction of the pulp layer. The apparatus of the invention preferably includes a rotating cylinder having a casing surface of which serves as the liquid-pervious support surface for the pulp.Type: GrantFiled: February 26, 1990Date of Patent: May 26, 1992Assignee: A.

Patent number: 5115653Abstract: A method for straightening sheet, strips, sections, girders, etc. The method includes measuring the straightening forces of at least one of the straightening rolls in a straightening machine and adjusting the positions of the straightening rolls in accordance with the measured values. The method further includes individually measuring the straightening force acting perpendicularly on the axes of rotation of the straightening rolls, and/or the roll bearings and/or the frame, and automatically readjusting the straightening rolls in dependence upon these measured values in a range of the occurring varying pressure forces.Type: GrantFiled: March 20, 1991Date of Patent: May 26, 1992Assignee: SMS Schloemann-Siemag AktiengesellschaftInventors: Gerd Beisemann, Klaus Pietsch
-
Patent number: 5115622Abstract: Metal reinforcing members (3) are attached by bonding to a surface in the tension zone (1a) of a concrete structure component (1) for reinforcing the component. To prevent the ends of the reinforcing members (3) from separating from the structural component (1) when the component is subjected to load, attachment elements (4) clamp the ends of the reinforcing members against the surface of the component in addition to the bonding action. The attachment elements (4) apply such high compressive forces to the structural component, so that potentially damaging tension and shear forces can not be effective.Type: GrantFiled: December 21, 1990Date of Patent: May 26, 1992Assignee: Hilti AktiengesellschaftInventors: Walter Ammann, Fritz Muenger, Manfred Hartmann

Patent number: 5116468Abstract: A method is disclosed for the preparation of finely divided, electrically conductive tin(IV) oxide. In a first step tin(IV) oxalate and/or oxalates of polymeric tin(IV) compounds are obtained by electrolysis, in which the anode consists of tin or a tin alloy which contains a doping metal, and the cathode consists of a metal or graphite. The two electrodes are separated by a diaphragm or an organic membrane which is permeable to hydrogen ions and oxalic acid solution is used as electrolyte. Tin(IV) oxide is prepared in the second step by calcining the oxalates obtained from the solution of tin(IV) oxalate and/or oxalates of polymeric tin(IV) compounds, to which known doping agents have been added in conventional amounts.Type: GrantFiled: October 15, 1991Date of Patent: May 26, 1992Assignee: Th.

Patent number: 5114444Abstract: A filter arrangement includes at least one drum-type filter. A suction device is provided for suctioning of the inside of the drum-type filter along a helical line. The suction device includes at least one suction hose and a suction nozzle provided at the free end of the suction hose. The suction nozzle is constructed for contacting the inner side of the drum-type filter. The suction hose is attached to an end portion of a rotatable suction pipe.

Patent number: 5114064Abstract: A powder charge operated setting tool includes a barrel (5) and a closing or breech member (8), both axially displaceable in a housing (1). Tensioning of a tension spring (18) for a firing pin (17) is made possible by means of a disengageable snap-in element (12) acting between housing (1) and closing member (8) by pressing the barrel (5) against the receiving material. The disengagement of the snap-in element (12) occurs only by overcoming a predetermined force acting counter to the setting direction which is generated by the gas pressure after a propellant charge (19) has been ignited.Type: GrantFiled: July 17, 1991Date of Patent: May 19, 1992Assignee: Hilti AktiengesellschaftInventors: Peter Jochum, Martin Muller
