Patent CA-1119065-A (CA)
Inventor: CLAXTON WILLIAM B
IPC: F02M63/00

Granted: 1982-03-02
Abstract: ELECTROMAGNETIC FUEL INJECTOR       A high flow rate electromagnetic injector valve with a rapid response time is disclosed for utilization in a single point fuel injection system.  Centrally bored end caps are fixed at the front and rear ends of a tubular injector body and a coil wound on a bobbin is disposed inside the body chamber between the end caps.  The front end  cap receives  within  its  bore  a  valve  assembly including a valve housing and a needle valve with attached armature  reciprocally movable  against  a  valve  seat  to obturate a metering orifice in the valve housing.   The valve housing contains fuel  inlets for  the pressurized entry of fuel into the injector and the needle valve is ported to provide fluid communication to the armature to relieve pressure build-up.   The rear end cap threadedly mounts within its bore a core member acting as a stator which extends through a central bobbin bore  to form a controllable air gap adjacent the armature, and further contains internally an adjustment screw and ball member. The ball member  and adjustment screw cooperate with a recessed closure spring positioned substantially within the armature to controllably bias the needle valve against the valve seat.   Because of its recessed position,  the force of the closure spring is applied substantially along the central axis of the injector valve and the ball member prevents tortional windup forces from being generated by the spring.  O-ring seals for the bobbin bore are provided in compression between recesses  in  the bobbin and the slower contracting material of the front end cap and core member to produce extended cold temperature operation.

Abstract: ABSTRACT OF THE DISCLOSURE               This invention relates to a method and apparatus for forming glass fibers.  The invention com-prises flowing streams of molten glass from a stream feeder through orificed projections depending from the feeder floor, directing gas upwardly into contact with the streams of molten glass at a velocity and in an amount effective to convey away from the streams sufficient heat to render the glass of the streams attenuable to fibers without appreciably disturbing the ambient gas above the streams in the region between the orificed projections and attenuating fibers from the streams of molten glass.

Abstract: BGD&R                  ABSTRACT            A belt clamp for use in a vehicle passenger restraint belt system comprises a pair of jaws, one of which is movable relative to the other, such as by a lever, is normally held away from the other by a spring, and is moved toward the other in response to an abnormally high pull-out force on the belt to engage a restraint belt guided between the jaws.  A multiplicity of spaced-apart, elongated straight teeth oriented widthwise of the belt and of uniform, smoothly curved cross section frictionally clamp the belt against pulling out by tucking loops of the belt into complementary recesses in the other jaw.  Preferably, both jaws have substantially identical teeth and substantially identical recesses which are generally complementary to the teeth, the shapes of the teeth  and recesses being such as to produce a smoothly corrugated clamping section in which several loops of the belt are formed and by which frictional holding forces are developed without any cutting or abrading of the belt.  Advantageously, small variations in gripping faces of the jaws compensate for variations in the properties of the belt (e.g., thickness, density and elasticity) and for deformation of the jaws.

Abstract: ABSTRACT OF THE DISCLOSURE:           A chain saw guide blade includes a pair of side plates between which an axle is fixedly supported and a sprocket is rotatably supported with respect to the axle.  The sprocket is rotatable about the axle with roller bearings therebetween for guiding a cutter chain for movement around the edge of the guide blade.  A pair of annular seals are respectively disposed between the sprocket and one of the side plates and between the sprocket and the other side plate.  Each of the seals includes an annular lip projecting obliquely into resilient contact with a surface of the sprocket or of one of the side plates.  A grease-supply aperture in each side plate is normally closed off by a flap on the annular seal or resilient valve means placed in a central hole of the axle.  When under the pressure of forced grease through the aperture, the flap or valve means is resiliently yieldable to allow the grease to be introduced for the lubrication of the roller bearings.

Abstract: COLLAPSIBLE SOLUTION CONTAINER               HAVING RECTILINEAR SHOULDER                 Inventors:  Jerry D. Martin Stephen J. Pearson Gary A. Ward David A. Winchell ABSTRACT OF THE DISCLOSURE     A molded collapsible solution container which container defines a chamber-defining body portion wall having an integral neck portion and shoulder portion at one end thereof.  The container defines, in its normal, unstressed state, a transverse cross section which tapers from the shoulder portion progressively along a major portion of its length to a flat, sealed end portion at the end of the container opposite to the one end.  In ac-cordance with this invention, the shoulder portion is rec-tilinear in shape, with the wail circumferences of trans-verse cross sections preferably progressively decreasing in length along the container from adjacent the shoulder portion toward the opposite end.  Opposed triangular gus-set portions are preferably present in which the side of the gusset portion which is parallel to the shoulder edge is positioned directly against the shoulder edge, and the shoulder edge defines the shape of an enlarged, generally cylindrical section for ease of flexing.  Flat areas are defined in the container wall between the gussets.

Abstract: ABSTRACT OF THE DISCLOSURE             A blank and method for its manufacture which blank is useful in the preparation of printed circuit boards. The blank comprises an insulating substrate, typically impregnated with an epoxy resin and with reinfo???? fiber glass.  Superimposed and adhered to at least one surface of the substrate is a high temperature thermoplastic polymer film or sheet having a substantially uniform thickness between about 10 and about 500 microns.  The thermoplastic polymer surface can be chemically treated to activate it and facilitate subsequent deposition of an adherent film of electrolessly deposited metal thereon.  The circuits formed by such deposition are uniform, have excellent adherence of a conductor pattern to the thermoplastic polymer surface, have excellent electrical properties and resist heat in continuous use or when soldered.

One end joke of the joint has a plurality of cir-cular ridges or gear teeth facing the other end yoke with the center line of the gear teeth being coaxial with the axis of rotation of the one yoke. The other end yoke has a plurality of circular ridges or gear teeth facing the one end yoke with the center line of those gear teeth coaxial with the axis of rotation of that yoke. The teeth are positioned so that one tooth extends between two teeth of the other yoke for any position of the end yokes and the drive and driven mem-bers or shafts to which they are attached. One of the end yokes has a gear-tooth shaped projection at the center line and the other has a gear-tooth shaped recess at its center line. The sets of teeth are in patterns of sphere segments so that any longitudinal cross section taken centrally through the gear teeth has the same appear-ance as a spur gear segment. The tooth profile is such that points of contact are always on the pitch radii at the intersection with a line through the center of the sphere segments of the gear teeth.

Alternatively, two opposing and contacting graphite rings (120),(130) are mounted in non-conducting carriers (122),(132), one of the carriers keyed for rotation with the sensor while the other is mounted on the relatively stationary member.  Electrical connections are made directly from the sensor to one of the graphite rings and from the detector to the other of the graphite rings and the rings therefore function as the electrical interconnection between the rotating sensor and the relatively stationary detector.
