-
Patent number: 4028784Abstract: A preloaded tie rod end assembly for a motor vehicle steering system and the method for making the assembly is disclosed. The tie rod end is made by positioning first and second frangible bearings against the ball of a ball stud and enclosing the ball and bearings in first and second housings each of which has a socket part and a stem part. A plastically deformable element is also situated within the socket formed by the two socket parts. The two housings are held together under a compressive load while their abutting edges are butt welded. The imposition of this load during the welding operation causes the frangible bearings to each fracture into a plurality of self-aligning bearing pieces. The deformable element is plastically deformed by exerting a force on the ball stud whereby a portion of the preload of the joint is relieved. The preload is relieved to the extent necessary to bring the frictional resistance to rotation of the ball stud within a prescribed torque range.Type: GrantFiled: April 12, 1976Date of Patent: June 14, 1977Assignee: Ford Motor CompanyInventor: William D.

Patent number: 4028789Abstract: Method for explosively expanding sleeves into heat exchanger tubes disposed in a tube sheet utilizing shaped charges in conjunction welding and brazing techniques to affectuate tube modifications and repairs including the steps of shaping the sleeve, placing specially shaped inserts into the sleeves, varying the explosive charges within the inserts and varying the confinement of the explosive charge within the insert to explosively weld the sleeve to the tube, expand the sleeve to the tube, and/or expand the tube to engage the tube sheet and welding or brazing one end of the sleeve to the tube to form a seal.Type: GrantFiled: March 29, 1976Date of Patent: June 14, 1977Assignee: Westinghouse Electric CorporationInventor: Emil P. Loch

Patent number: 4028790Abstract: The removal of connector pins from a panel, such as a printed circuit board, in which the pin extends from the panel and is soldered to a circuit member on one or both sides of the panel, is achieved by a tool positioned over the pin and having a main body member which is held in contact with the panel surface and with an axially sliding gripping member having a split gripping portion. The gripping member is moved by a tubular member surrounding the gripping member and which, on axial movement, forces the split gripping portion of the gripping member into firm frictional contact with the pin, further axial movement of the tubular member moving the gripping member and pin axially shearing the solder joint. The tubular member is moved by a pivotally mounted handle, the reaction from the pivoting of the handle and pulling on the pin holding the tool firmly against the panel. The pin is removed without damage to the panel and a new pin can be inserted and resoldered using the remaining solder at the joint.Type: GrantFiled: March 25, 1976Date of Patent: June 14, 1977Assignee: Northern Telecom LimitedInventor: Jean Marcel Dupuis

Patent number: 4028791Abstract: The invention relates to apparatus and a method of conveying, orienting, transferring and debunging empty beverage kegs. The apparatus includes a keg elevator for raising the kegs to the uppermost of a series of superposed endless conveyor belts. The tension of the latter is such that, where they face one another, they engage the periphery of each keg and urge it along the path of travel.Type: GrantFiled: August 10, 1976Date of Patent: June 14, 1977Assignee: The Molson Companies LimitedInventor: Ernest J. Hodgetts

Patent number: 4028792Abstract: A tower crane is erected from a boom assembly, first and second tower sections of different cross section, and a base in a sequence of steps in which the boom assembly is mounted on a hollow climbing section dimensioned to be received in each of the larger second tower sections and defining a cavity dimensioned to receive each of the first tower sections. One of the latter is secured on a base in upright position, and the upright section is received in the cavity of the climbing section which is then raised relative to the first section and enveloped by one of the second sections. The enveloping section is secured to the base and the raised climbing section for supporting the climbing section whereupon the first tower section may be rleased from the base, raised, and secured to the second tower section.Type: GrantFiled: April 29, 1976Date of Patent: June 14, 1977Assignee: Hans TaxInventors: Hans Tax, Klaus Hosler

Patent number: 4028793Abstract: A power resistor including a resistance element of metal ribbon formed into an edgewound helix, and an internal three-point support structure axially disposed within the interior of the helix. The support structure includes three insulating assemblies each having a plurality of insulators secured by longitudinal compression springs to a support bar. The support structure also includes a pair of spreaders located at opposite ends of the helix, each having three radially extending arms. Assembly of the resistor includes the steps of inserting the insulating assemblies into the interior of the helix, radially spreading the insulating assemblies against the interior of the helix, and welding the ends of the support bars to the extending arms of the spreaders.Type: GrantFiled: September 13, 1976Date of Patent: June 14, 1977Assignee: Westinghouse Electric CorporationInventors: Marvin E. Liebler, Eugene J. Lum

Patent number: 4028794Abstract: A connector is disclosed which is made from a plurality of electrical contacts, each of which is a resilient spring, spaced along a continuous web of insulative material which serves to locate the contacts in desired positions and provides an insulation back or cover for the contacts. The method and apparatus for making the subject laminated connector is also disclosed. The plurality of contacts are first formed from a continuous strip of metal, an insulative web is laminated to the metal contacts, and the laminated connector is bent by a continuous roller or die forming operation to desired curvilinear arcuate shapes. Discrete lengths of contacts formed together with the carrier strip are broken away or otherwise separated from the carrier strip either prior to or after the bending operation.Type: GrantFiled: January 7, 1976Date of Patent: June 14, 1977Assignee: AMP IncorporatedInventors: Leon Thomas Ritchie, Robert George Harwood

Patent number: 4028795Abstract: Aluminum or aluminum alloy scraps or wastes are broken into chips and converted into a cylindrical body to be extruded under a temperature suitable to produce extruded structural profiles. The method is characterized by the fact that the interior of the extruder is evacuated prior to or simultaneously with the extrusion step so as to exhaust air entrapped in the cylindrical body.Type: GrantFiled: July 8, 1975Date of Patent: June 14, 1977Assignee: Riken Keikinzoku Kogyo Kabushiki KaishiInventors: Toshiro Takahashi, Toshihiro Nagano, Katsuhiko Nakamura, Masaru Kikuchi
