Albertson
-
Patent number: 4146666Abstract: An expansible panel capable of deforming and absorbing stresses caused by thermal expansion and contraction comprising a single sheet formed of a plurality of frusto-pyramids of different sizes, each having a base, a top and depending sides and whose dimensions are such that any combination of frusto-pyramids will not produce a straight line longer than 1.5 times the base of the largest pyramid.Type: GrantFiled: August 8, 1977Date of Patent: March 27, 1979Assignee: Borg-Warner CorporationInventor: Wim J. Houtlosser
-
Patent number: 4141932Abstract: A method of preparing a graft ABS polymer comprising first preparing a rubbery graft ABS polymer by emulsion polymerizing acrylonitrile and styrene in the presence of a rubber, coagulating the emulsion and then polymerizing a mixture of acrylonitrile and styrene in the presence of the coagulant and an organic or inorganic suspending agent to form bead-like particles of ABS.Type: GrantFiled: October 3, 1977Date of Patent: February 27, 1979Assignee: Borg-Warner CorporationInventor: James M. Butler
-
Patent number: 4132748Abstract: Disclosed are flame-retardant thermoplastic resins such as graft ABS, polystyrene, polypropylene, and the like, containing polyethylene tetrabromophthalate and antimony trioxide.Type: GrantFiled: April 25, 1977Date of Patent: January 2, 1979Assignee: Borg-Warner CorporationInventors: Ralph P. Arthur, Roy M. Turner

Patent number: 4094217Abstract: An automatically retractable slitter for cutting thermoplastic sheet as it exits from the sheet die of an extruder comprising a housing, a cutter blade mounted in a holder, a recess in the housing of a length greater than the length of the holder for slidably and retractably receiving the holder and blade, an elongated slot in said housing having detent means, an elongated pin secured to said holder and extending transversely through the elongated slot, spring means between the holder and the housing adapted to be relaxed when the holder is in its retractable position within the recess, the pin being adapted to rest in the detent when a cutting force is applied to the blade and to disengage from the detent when no force is applied to the blade.Type: GrantFiled: June 28, 1977Date of Patent: June 13, 1978Assignee: Borg-Warner CorporationInventor: Roger Edsel Exline
-
Patent number: 4093945Abstract: A breath testing system for under-supervised or unsupervised alcohol intoxication breath testing. The system includes a breath input unit, a controller which delivers a sample of deep lung breath to an evaluator including an alcohol detector and an output apparatus. The controller includes a breath flow sensing means, e.g., a pressure sensitive switch and timer, to require a predetermined and essentially continuous and uninterrupted breath flow prior to testing to thereby insure that alung breath sample is tested. Means for signaling failing or passing of the test are provided. A passing signal cannot be obtained unless the predetermined continuous nnd uninterrupted flow has occurred and the resulting sample tests below a predetermined alcohol concentration. The system is disclosed in one environment of use: in a motor vehicle, wherein failure to take or pass the test modifies the operation of the vehicle (e.g., prevents it from being driven or governs its maximum speed).Type: GrantFiled: April 23, 1971Date of Patent: June 6, 1978Inventors: Donald W. Collier, Joseph P. Hoppesch, Anthony C. Mamo

Patent number: 4088547Abstract: A solar heat collector comprising a metallic substrate having nodular or dendritic surfaces coated with a black absorber coating, and the method of preparing same.Type: GrantFiled: September 1, 1976Date of Patent: May 9, 1978Assignee: Borg-Warner CorporationInventor: Clarence E. Albertson
-
Patent number: 4060343Abstract: A rotary fluid compressor of the sliding vane type having a housing containing a closed working chamber and a rotor eccentrically mounted in the chamber. A control member is rotatably mounted in the housing and provided with an elongated arcuate aperture in fluid contact with the working chamber and spanning at least one of the vanes to permit fluid to bypass the vanes and thereby change the compression volume in the chamber.Type: GrantFiled: February 19, 1976Date of Patent: November 29, 1977Assignee: Borg-Warner CorporationInventor: Alwin B. Newton
-
