Patent CA-1117363-A (CA)

Abstract: Abstract of the Disclosure A print head for a serial dot matrix printer comprising a sandwich structure including a base plate, a segmented-ring magnet, a print hammer disc and face plate is disclosed. The segmented-ring magnet comprises a ring formed of a magnetic material having spaced apart, magnetized, regions (segments). The print hammer disc is formed of a magnetically permeable, resilient material and has a plurality of inwardly projecting arms (hammers), each of which is aligned with a magnetized segment. Mounted on the hammers are print blades, which are aligned with radial slots formed in the face plate. Each print blade includes a dot-printing tip that projects orthogonally outwardly from the blade,and lies in a central aperture in the face plate. Mounted on the base plate, in line with each hammer, is a post having a coil mounted thereon. When the coils are de-energized, the magnetic field formed at the tips of the posts is adequateto overcome the spring force of the related hammer, whereby the air gap therebetween is closed and the hammer is cocked. Energization of any coil by a pulse of appropriate polarity and magnitude cancels the magnetic pull created bythe related magnetic segment and allows the related hammer to pull away from the related post. This action creates a dot as the released spring force causes the dot-printing tip of the related print blade to press a print-producing material (e.g., a ribbon) against a print receiving medium (e.g., a sheet of paper). Rather than defining a single column, the dot-printing tips define two or more columns

Abstract: DESCRIPTIF L'invention concerne les câbles pour la transmission numérique constitués d'un certain nombre de quartes torsadées, chaque quarte ayant un pas de tordage particulier, plusieurs quartes étant regroupées en une ou plusieurs couches dans un faisceau, et quatre faisceaux étant regroupés dans le câble. En vue de la réduction de la diaphonie, surtout aux fréquences élevées utilisées pour la transmission numérique, on propose de n'admettre une identité de pas de tordage que sous certaines conditions. On obtient ainsi un câble d'une complexité réduite permettant un remplissage complet des circuits par des signaux numériques.

Abstract: Abstract of the Disclosure In a heat storage device comprising a container which contains a salt hydrate, the heat of fusion of which is utilized to provide high heat capacity in ralation to the volume, oil is circulated by a pump through a number of channels leading to outlet openings dis-tributed in the salt hydrate. A slide valve, the sliding valve body of which is influenced by the pressure on the delivery side of the pump, automatically controls the distribution of oil to the channels in such a manner that solidification of the salt hydrate during heat discharge from the storage takes place in a regu-lar progressive way so that the oil can always find non-blocked outlet openings to flow through.

Abstract: VISUAL MOTION TRACKING SYSTEM          Abstract of the Disclosure The movement of an article such as a product carried by a conveyor is monitored by providing a patterned target, preferably striped with contrasting lines, to move with the object.  A solid state line scan camera views the pattern of the target as it moves relative to the camera and the electronic output of the camera representing the light and dark areas of the target is analyzed by an electronic circuit to determine the movement of the target and therefore of the object being monitored.  The resulting electronic signal representing the motion of the object is useful for coordinating the movement of a robot which is operating upon the object during its movement.

Abstract: (Case No. 7032) ABSTRACT OF THE DISCLOSURE    A low-profile railway car retarder having a pair of braking bars disposed parallel and on opposite sides of a track rail and having an upper and lower pivotal lever carrying a respective one of the pairs of braking bars.          A pneumatic motor pivotally connected to the outer extremi-ties of the upper and lower levers, and the height of the pivotal connection of the upper lever is substantially at the same level as the track rail so that a humped railway vehicle is permitted to freely pass through the car retarder.          The pneumatic motor lifts the upper lever and depresses the lower lever to move the pair of braking bars to a closed braking position wherein pressure is supplied to the pneu-matic motor so that the pair of braking bars engage the opposite side of the wheels of a traversing vehicle at a relatively high point to exert a greater amount of retarda-tion of the vehicle.

The system is comprised of an analog video storage unit which stores a composite video signal having red, blue and green video components and having an associated video information content and provides as a video output signal the composite analog color video signal at a real time video frame rate.  A decoder is connected to the storage unit for receiving the composite analog color video signal and for decoding the signal into the red, blue and green analog video components.  The decoder is capable of providing decoded red, blue and green analog video components as separate red, blue and green analog video output signals at the real time video frame rate.  A real time video processor is connected to the decoder for receiving the red, blue and green video output signals.    The processor includes a digitizer which digitizes the red, blue and green video output signals and digitally processes those signals in a 4:3 aspect ratio configuration of active pixels.  A real time interactive unit is connected to the processor for enabling real time interactive controllable digital processing of the associated video information content of the digitalized red, blue and green signals on an active pixel-by-pixel basis by the processor.

Abstract: ABSTRACT OF THE DISCLOSURE         A fire-safe rotary valve seat assembly for use in pressurized fluid systems subject to fire risk, the seat assembly having both a metal seat ring and an annular resilient non-metallic seal member to provide essentially zero fluid leakage at normal operating temperatures, and the metal seat ring to provide an extremely low rate of fluid leakage in the event high temperature should destroy the flexible seal member.          The metal seat ring includes an annular groove around its radially inward face with a pair of flexible lips forming the walls of the groove, and the annular resilient seal member is mounted in the groove between the lips.  The lips and the annular resilient seal member both engage a sealing surface on the circumference of a metal valve disc to provide a primary seal for the valve.  If the-annular resilient seal member is destroyed, the metal lips continue to provide an undamaged secondary seal.
