Patent CA-2080723-A1 (CA)
Title: Method and apparatus for defining a template for assembling a structure
Inventor: PETTA GABRIEL
IPC: B25H7/00
Filed: 1992-10-16
Abstract: A method and apparatus for generating a template for use in assembling a structure such as a truss. One or more laser scanners mounted above a work surface are controlled by a computer to generate a scanning laser image of all or a portion of the structure. The computer receives data describing the relative location of the individual work pieces in their assembled positions and the position of the laser scanner relative to the work surface. The computer generates a set of template defining data which is converted to a control signal and transmitted to the laser scanner.

Patent CA-2088146-A1 (CA)
Inventor: MUNGER JOSEPH H
IPC: C08K5/00
Filed: 1991-07-19
Abstract: A preferred embodiment of the process and apparatus for recycling used automobile rubber tires is described in which small pieces of rubber tires are progressively fed into a vertical reactor of the counter-flow type in which the material progressively descends downward through the reactor with process gases passing upward through the downwardly descending material to decompose and volatilize the rubber material. At the lower portion of the vessel, oxygen-bearing gas is injected into the reactor to burn a portion of the rubber carbon to generate hot combustion gases that ascend upwardly to pyrolitically decompose the rubber pieces, and to volatilize such material.      The amount of oxygen is controlled in an oxygen-deficient manner to maintain the temperature in the combustion zone at a temperature of less than 500 °F. The gases and volatilized rubber materials and oils are removed from the reactor at a temperature of approximately 350 °F at an elevation below the top layer of the rubber pieces in a high velocity stream to maintain the oils entrained in the air stream. The air stream is directed into condensers for condensing the rubber process oils. The raw rubber process oils are subdivided to obtain a residue heavy fraction rubber oil material having a flash point of greater than 340 °F and greater at one atmosphere and a boiling point of greater than 450 °F at 20 mm Hg for use as an extender/plasticizing agent in rubber compounding in which such agent has shown to exhibit unusual and unexpected results. The oxygen-baring gas is initially maintained at a temperature of between 40 and 60 °F and is then passed through the condenser as the cooling agent before it is passed into the reactor. Consequently, the air-bearing gas serves as the cooling agent in the condenser and also as the oxidizing agent for burning a portion of the carbon in the reactor to generate the desired temperatures.

Abstract: The invention relates to an applicator beam in a size press comprising a nip formed by a pair of press rolls between which a paper or board web is passed. The press rolls are provided with coating devices for spreading films of coating agent onto the faces of the rolls. The coating devices are mounted on applicator beams placed in the transverse direction of the machine. The applicator beams are linked pivotally on the frame of the size press or on the loading arms of a displaceable roll by means of a pivot shaft arranged transverse to the machine direction. The applicator beams are also provided with pivot cylinders by whose means the applica-for beams can be pivoted between a closed position, i.e. the operating position, and an opened position, i.e. the service position. In accordance with the invention, in its cross section taken in a vertical plane in the longitudinal direction of the machine, the applicator beam is shaped so that at least the curved outer face of the applicator beam that is facing away from the corresponding press roll is curved. Moreover, the pivot shaft of the applicator beam is arranged so that when the applicator beam is pivoted around its pivot shaft, the distance from the curved outer face of the applicator beam to the other constructions of the machine placed close to the applicator beam, such as the tending bridge, remains substantially unchanged.

Abstract: ABSTRACT OF THE DISCLOSURE      In electrostatic imaging utilizing a silent electric discharge, nitrogen or other controlled gas is supplied to the discharge region.  First and second control fingers each having first and second ends and a number of active openings along their lengths, provide electrodes at the discharge region. The controlled gas is supplied to the discharge regions through first and second gas input channels each connected to either the first ends or second ends of both the control fingers.  The charge output associated with the active openings in the control fingers is stabilized so that there is a substantially even distribution of charge output along the length of each control finger by providing first and second bleed holes associated with each of the control fingers, and closer to the gas input channel than are the active openings in the control fingers.  Each bleed hole has a surface area of approximately three times that of a single active opening if each control finger has sixteen active openings, and the bleed holes are preferably formed in a screen electrode overlying the control fingers.

Title: Ester polymer compatibilizers
Inventor: SATO KYOSAKU
IPC: C08L23/08
Filed: 1993-11-12
Abstract: Ester Polymer Compatibilizers Polyethylene has a number of desirable properties. However, for some thin film applications it is desirable to increase the stiffness of the film. This may be accomplished by incorporating a polymer of a vinyl aromatic monomer into the alloy. Such two-component blends have a low impact and low tear resistance. These deficient properties of the alloy may be significantly increased, without any significant loss of stiffness by further incorporating into the alloy a polymer based on a copolymer of ethylene and an alkyl ester of an ethylenically unsaturated carboxylic acid.

Patent CA-2110720-A1 (CA)
Title: Filtration process and apparatus
Inventor: LARSSON HANS F
IPC: B01D24/30
Filed: 1992-06-03
Abstract: It is known to filter a suspension or emulsion in a filter bed of particulate filter medium (1) by allowing the suspension to flow upwards through the filter bed simultaneously as the medium (1) flows downwards through a filtering tank (2) wherein filtration takes place. Filtration thus takes place during counterflow between suspension and filter medium. The supply of suspension takes place in the lower part (4) of the filter bed and the filtered liquid phase is taken away from a zone (8) above the filter bed. The polluted filter medium close to the bottom of the filter tank is taken out for conveyance to a washing apparatus (13) above the filter bed and after washing is returned to the upper side of the filter bed. For providing a filter which has a considerably lower construction height than previously for a given and unchanged volume of the filter medium, the washing apparatus (13) is now lowered so that its lower part is at a level below the upper surface of the filter bed.

Title: Air separation process and apparatus for the production of high purity nitrogen
Inventor: SWEENEY PAUL A
IPC: F25J3/04
Filed: 1994-06-16
Abstract: ABSTRACT     A process and apparatus for producing a high purity nitrogen vapor product from the rectification of air within high and low pressure columns operatively associated with one another by a condenser-reboiler. The high pressure column incorporates a sufficient number of theoretical stages to produce a high purity nitrogen vapor which after being condensed by the condenser-reboiler, serves to partially condense a lower purity nitrogen vapor tower overhead produced in the low pressure column through indirect heat exchanger. In such service, the condensed, high purity nitrogen vapor is at least partially vaporized and utilized as a product stream. Since there is no direct heat exchange with the high purity nitrogen produced within the high pressure column and the lower purity nitrogen vapor produced in the low pressure column, the low pressure column can incorporate fewer theoretical stages and therefore can be built at less expense than similar air separation plants of the prior art.
