Patent CA-1115914-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus for making bilaminar sheet material which is eminently suitable for usage in the packaging of goods.  The sheet material is characterized by the presence of raised pockets on a continuous bilaminar planar sheet element or web.  The pockets contain a gas, such as air or a gas lighter than air.  The sheet material is made by extruding of heating elements arranged around the circumference of the annular circular slot to maintain the temperature of the extruded material at various points around the circumference of the annular slot at difference temperatures as it exits said slot.  This circumferential variation of temperature results in the formation of a molten tubular element having a plurality of linear sidewall portions of unequal thicknesses relative to each other upon exit from the nozzle, which subsequently adjust to a uniform thickness prior to being collapsed, thereby resulting in the formation of a uniformly thick bilaminar sheet.  Concomitantly with the extrusion, a slightly pressurized gas such as those mentioned above is discharged into the slotted extruder, typically through a central opening in the extruder, so that the gas fills and expands the tubular hollow element. Then the tubular element containing the gas is passed between two juxtaposed parallel cylindrical rollers which rotate in opposite directions so as to draw the tubular element into the nip between the rollers, and thereby collapse and flatten the tubular element into a continuous bilaminar planar sheet element or web.  At least one of the rollers is characterized by the provision of a plurality of speed apart recesses on its outer surface, e.g. grooves, cavities or apertures, so that the continuous bilaminar planar sheet material or element, i.e. the web, is formed with raised pockets containing the aforementioned gas.  The resulting sheet material possesses desirable attributes, for use in packaging of goods.

Abstract: ABSTRACT OF THE INVENTION         A high current  density cathode capable of operating at current densities to 2A/cm2 to 30A/cm2 in the temperature range of 900 degrees  C to 1125 degrees  C  is prepared by machining a porous high purity tungsten pellet containing copper in its pores and also containing about 0.6 to 2 weight percent of an activator to the desired cathode shape without reducing the pores of the emitter pellet.  The pellet is then fired at 1800 degrees C in a non-oxidizing atmosphere to remove the copper filler material.          The pellet is then impregnated with Ba5Sr(WO6)2 at a temperature or 1900 degrees C in a dry  inert gas atmosphere and the impreg-nated emitter then fired in dry hydrogen atmosphere at about 1840 degrees C for about 2.5 to 5 minutes.

Abstract: CARBON SPACER               Abstract of the Disclosure A spacer is used to set the running clearance bet-ween parts in a power transmitting device.  The power trans-mitting device contains a housing, a shaft rotatably mounted in the housing and a ring gear mounted on the shaft for rotat-ion therewith.  The ring gear is capable of deflecting in an axial direction under load.  A stop member, fixed to the hous-ing, is positioned to have one end adjacent one side of the ring gear.  The stop member is installed to be in abutting contact with the ring gear.  The spacer is formed of a mat-erial capable of wearing away when contacted by the rotating ring gear to produce a gap of a predetermined thickness bet-ween one end of the stop member and the ring gear.  The one end of the stop member will prevent the ring gear from de-flecting axially under load a distance greater than the prede-termined distance.

Abstract: ABSTRACT OF THE DISCLOSURE A flareless tube coupling having screwed together body and nut members provided with oppositely tapered cam surfaces operative upon screwing together of the body and nut members to contract a tapered C-shaped grip ring within the nut cam surface into gripping engagement with a tube therewithin and to urge the axially inner end of a thin tubular sleeve into sealed engagement with the body cam surface and into gripping and sealing engagement with the tube, the large end of the grip ring having a plane end surface in engagement with the plane end surface of a radially enlarged collar at the axially outer end of the sleeve.  In addition, the nut member has a shoulder at the large end of its cam surface which engages the radially outer portion of the plane end surface of the collar to limit contraction of the grip ring and to positively restrain the sleeve from axial outward movement with respect to the body member under the influence of fluid pressure in the coupling assembly or upon imposition of tensile pulling apart forces exerted on the tube and body member. The coupling herein is further characterized in that the C-shaped grip ring is uniformly radially and circumferentially contracted to sub-stantially circular form with the circumferentially extending gripper teeth of saw-tooth configuration terminating in sloping edges which fade out to the crests in spaced relation from the respective ends of the ring to preclude the possibility of circumferential pinching of the tube mate-rial during assembly of the coupling.
