Patent CA-1113178-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE               A method and apparatus for inspecting and sorting geometrically symmetrical stable units such as buttons and the like, having zones containing one or more orifices therethrough such as buttonholes.  The buttons to be inspected are fed to a velocity control system which imparts a uniform velocity to each button and propels it between a light source and detector.  The light from the source is controlled by a mask to limit the light to the central zone of the button.  The amount of light which passes through the central zone of the button is then converted to an electrical signal by the detector electronics.  The electrical signal is then compared to pre-set upper and lower limits.  If the signal falls within the pre-set limits, an accept signal is generated which is used to control a reject mechanism for automatic separation of buttons for collection and use.

Abstract: ABSTRACT OF THE DISCLOSURE A trailer suspension system eliminating jackknifing of the towing tractor and trailer assembly, providing stability to the trailer and more efficient braking especially during emergency stops and materially increasing vehicle maneuverability.  Steering control is provided by a connection with the towing tractor in laterally offset relation to the vertical pivot axis formed by the kingpin and fifth wheel articulate connection between the towing tractor and trailer.  The steerable wheels in the trailer suspension are sup-ported by a generally right angular spindle structure connected to walking beam assemblies for pivotal movement about generally vertical axes which are ori-ented forwardly of the horizontal axis of rotation of the steerable wheels with the spindle assemblies being interconnected by parallel, vertically spaced rods provided with universal connection with the spindle assemblies for main-taining proper orientation of the steerable wheels during their steering move-ment and during relative vertical movement.  The trailer suspension includes independently and resiliently supported axle and spindle assemblies in the form of a two axle or three axle tandem assembly with the resilient independent sup-port for the suspension axles effectively maintaining wheel contact with the ground surface for more effective braking and greater vehicle stability.

Title: High inertia rotor for a dynamoelectric  machine
Inventor: KAY JAMES V
IPC: H02K7/02
Filed: 1979-01-12
Granted: 1982-08-10
Abstract: ABSTRACT OF THE DISCLOSURE       This invention relates to a high inertia rotor for use in a dynamoelectric machine.  The inertia of the rotor is increased over that of standard rotors by providing a plurality of inertia packets secured to the shaft adjacent the ends of magnetic core and the rotor winding.  The inertia packets are enclosed within the stator of the machine.  The added inertia supplied to the rotor from the packets prevents a rapid decrease in rotor speed upon interruption of electrical supply to the machine.  Each inertia packet is comprised of unifrom non-magnetic discs of metallic sheet material having minimal electro-magnetic losses.  In the event of rotor failure leading to the fracture of a disc, some disc fragments would be propelled into the stator winding, resulting in the creation of an electrical fault condition, whereby the motor would trip out before additional damage could occur.          This rotor is particularly suited for use as a pump motor in a nuclear reactor.  Previous practice in providing additional inertia has been to use a solidly forged fly-wheel mounted outside the stator winding.  Such flywheels due to their location and concentrated mass, necessiatated the provision of shielding about them to contain fragments from a fractured flywheel which could otherwise become projectiles in the environment surrounding the flywheel.          The present invention eliminates the need for such a prior art flywheel, with its associated shielding, while reducing the overall size of the high inertia machine.

Abstract: Docket 6460 LAMINATED WEB AND PROCESS OF MANUFACTURING               Abstract of the Disclosure The gas and light barrier properties of a web of thermoplastic bags designed for aseptic packaging are improved by laminating a material of high gas and light imperviousness, such as metal foil, to the thermoplastic bag material during a blown film extrusion process.  In one embodiment a pair of foil laminates are applied to opposite sides of the inflated length of a blown tube between the extruder and a first pair of nip rolls, with the laminates being pressed into opposite sides of the inflated tube by rollers which flatten the tube at their points of contact to provide flat surfaces for the laminates being applied to the tube.  The resulting laminated web has a pair of aligned, uncovered strips running the length of the web along which a slit-seal is made to provide a pair of webs each having a layer of foil or other material laminated to all but one longitudinal edge thereof.  In another embodiment a single sheet of foil is applied to a tube of film using, for example, a conventional tube former, with the foil wrapping less than the full circumference of the tube to provide a single web having an uncovered section running longitudinally thereof.

Abstract: ABSTRACT OF THE DISCLOSURE:           A closing and locking device for a press comprising a stationary plate, a stationary head spaced from the stationary plate, and a mobile plate movable toward and away from the stationary plate.  Movement of the mobile plate is controlled by a double acting piston-cylinder mechanism.  A toggle arrangement is pivotally connected between the mobile plate and the stationary head.  A second double acting piston-cylinder mechanism operates, after the first piston-cylinder mechanism moves the mobile plate toward the stationary plate, to position the toggle arrangement for locking the mobile plate in place.  The entire closing and locking device is arranged within the external contour of the press.  The toggle arrange-ment plays no part in the major portion of the movement of the mobile plate with respect to the stationary plate, but is activated only to lock and unlock the mobile plate.  Provision is made for slowing the flow of fluid to the first piston-cylinder device to permit degassing during compression molding of resins containing expanding agents.

Abstract: RCA 72,669 Abstract of the  Invention Brightness control apparatus for a video signal image reproducing system including a video signal processing channel, a kinescope driver for supplying video signals to an image reproducing kinescope, and a source of sub-stantially fixed potential to which signals processed by the kinescope driver are referenced.  A comparator senses the substantially fixed reference potential and a blanking level which occurs during periodic blanking intervals of the video signal, and provides an output control signal indicative of the voltage difference between the reference potential and the blanking level.  The control voltage is applied to the video channel for translating the blanking level in a direction to minimize the voltage difference, to thereby establish the conduction of the kinescope driver during image intervals of the video signal at a level corresponding to a desired image black level condition when such condition is manifested by the video signal.
