Patent number: 4333659Abstract: A shaft seal arrangement for turbochargers comprises a two piece wear washer for preventing passage of bearing lubricant into the turbocharger turbine housing. The two pieces of the wear washer seal respectively with the turbocharger shaft and with the turbocharger bearing housing. The two pieces of the wear washer further cooperate with each other to form a radially displaceable seal arrangement to accommodate radial excursions of the shaft without leakage of bearing lubricant.Type: GrantFiled: July 28, 1980Date of Patent: June 8, 1982Assignee: The Garrett CorporationInventor: Craig A. Gibbs

Patent number: 4312484Abstract: A flow control is provided between an inflatable and a smaller inflatable log which positions the inflatable with respect to the craft to which it is affixed. The flow control permits the inflation of the positioning log through the inflatable but restricts the flow of fluid back from the positioning log to the inflatable.Type: GrantFiled: May 4, 1979Date of Patent: January 26, 1982Assignee: The Garrett CorporationInventor: David J. Meisner

Patent number: 4300587Abstract: An absolute pressure relief valve including a venturi and a diaphragm, for limiting the discharge pressure of an aircraft compressor.Type: GrantFiled: November 30, 1979Date of Patent: November 17, 1981Assignee: The Garrett CorporationInventor: John C. Daeschner
-
Patent number: 4279570Abstract: An energy transfer machine including a stator ring carried in a casing forming a toroidal fluid path between a fluid inlet and a fluid outlet. A rotor has a blade cascade coacting with fluid in the path to transfer energy therebetween. Apparatus and methods are disclosed for controllably unloading the energy exchange between the rotor and the fluid.Type: GrantFiled: July 25, 1979Date of Patent: July 21, 1981Assignee: The Garrett CorporationInventors: Hans Egli, Joe L. Byrne, James H. Nancarrow

Patent number: 4246963Abstract: A plate-fin heat exchanger for transferring heat energy between heated air and relatively cold air, including elongated rounded surface hollow header bars traversing the cold air inlet for passing a portion of the hot air thereacross to prevent excessive ice formation.Type: GrantFiled: October 26, 1978Date of Patent: January 27, 1981Assignee: The Garrett CorporationInventor: Alexander F. Anderson

Patent number: 4215366Abstract: A method and apparatus for encoding and decoding of standard television signals are provided for enabling reception thereof in an intelligible manner only by authorized subscribers. The scrambling of the video signals is effected by inversion of the video signals of some horizontal scan lines on a pseudo-random basis to produce a picture having some video signals inverted and others not inverted which is unpleasant to view and virtually unintelligible. The scrambling of the audio signals is effected by conversion of analog audio signals to coded digital audio signals. A plurality of unique pulse coded control signals consisting of 32-bit binary pulse trains are transmitted separately to identify individual authorized subscribers and to provide information needed to unscramble the scrambled video and audio signals.Type: GrantFiled: April 24, 1979Date of Patent: July 29, 1980Assignee: Feature Film ServicesInventor: Richard A. Davidson

Patent number: 4207681Abstract: An apparatus for reforming and straightening damaged bodies and frames of vehicles whereby corrective forces are applied to the vehicle through one or more elongated force transmission elements. A force is imposed on the elongated elements respectively by means of a uniquely mounted hydraulic ram which is freely pivotable sideways and limitedly pivotable in a backward direction. Each of the hydraulic rams are attached to a frame situated beneath the vehicle to be straightened whereby the frame further supports a measuring bridge coupled to the vehicle so that the progress of a straightening operation can be readily determined. The measuring bridge includes vertical indicators or gauges which are coupled at datum points on the vehicle so that an operator can readily determine the deformity of the vehicle longitudinally, laterally and vertically with respect to its center line.Type: GrantFiled: August 12, 1977Date of Patent: June 17, 1980Assignee: Applied Power Inc.Inventors: Jeffrey T. Bayorgeon, Dirk J. van Dalen, Pierre N. Legrand

Patent number: 4195719Abstract: The fastening of a diaphragm spring to the casing of a clutch is effected by means of a annular piece that acts elastically on the diaphragm independently of the riveting, offering a high degree of resistance to flexion between rivets, which piece is of a hollow and incomplete toroidal shape in a support zone on the diaphragm, which zone presents an angular extension of more than 180.degree., permitting an elastic deformation or a reduction of its height of assembly without exceeding the elastic limit of the material that originates the elastic force necessary for the perfect operation of the device and at the same time absorbing the dimensional differences due to the necessary and admissible tolerances of manufacture, with the special feature that the interior part of the said piece is provided with a flange for increasing the moment of inertia of the section of the piece, increasing resistance to flexion between two consecutive orifices of the said piece.Type: GrantFiled: October 27, 1977Date of Patent: April 1, 1980Assignee: Francisco Montoro MunozInventor: Cecilio Corral Martinez
