Patent CA-2002703-A1 (CA)
Title: Filling nozzle cut-off valve
Inventor: PHALLEN IVER J
IPC: B65B39/00
Filed: 1989-11-10
Abstract: The invention relates to a filling nozzle cut-off valve for use in liquid filling machines and in particular to a valve assembly suitable for use with virtually all fluids.  In general, the valve assembly includes a valve head having an operational surface and a valve body having a smooth surface aligned with the operational surface of the valve head.  Inlet and outlet passageways extend from ports to a plurality of passageway openings in the smooth surface area of the valve body and the operational surface of the valve head has a shallow recessed portion and an annular ramp opposite the passageway openings.   A compressed air line is adapted to receive air under pressure to normally hold the diaphragm against the smooth surface of the valve body.  When the fluid in the inlet passageway is subject to a pressure greater than the air pressure, the diaphragm shifts away from the smooth surface permitting the fluid to flow from the inlet passageway opening to the outlet passageway opening.

Title: Volatile liquid catalyst handling system including distribution cabinet (13516-ca)
Inventor: WEHR CRAIG M
IPC: B22C9/12
Filed: 1990-04-09
Abstract: VOLATILE LIQUID CATALYST HANDLING SYSTEM    INCLUDING DISTRIBUTION CABINET     Abstract of the Disclosure A system for delivering liquid catalyst to a core-making machine includes a single fireproof cabinet in which is located a catalyst storage tank.  The storage tank receives catalyst from catalyst supply drums that are positioned one at a time in a pumping station located in the cabinet beside the tank and emptied into the tank by a barrel pump.  A flash-off station is located in the cabinet beside the pumping station for receiving emptied drums and an exhaust hose, that is coupled to a scrubber system exhaust duct, is positionable within the drum to carry away vapors produced in the drum as residual catalyst flashes off.  A catalyst supply pump is coupled for pumping liquid catalyst from the storage tank to a gassing unit of a core-making machine.  Excess catalyst is returned from the gassing unit to the storage tank by way of a water-cooled heat exchanger which cools the returning catalyst and hence that remaining in the tank so as to keep the catalyst at a temperature low enough to prevent its vaporization and thus the vapor locking of the supply pump.

Title: Manufacture of extruded products
Inventor: HOWELL BARRY G
IPC: C08F291/00
Filed: 1990-06-13
Abstract: ABSTRACT Manufacture of Extruded Products Polymeric material is plastified in an extruder and is then divided into a major part and a minor part. Either the major part or (more often) the minor part is modified by a chemical reaction, such as grafting (any necessary ingredients being added, if not already present). The major and minor parts are then recombined in an extrusion head so that the modified and unmodified materials form distinct parts of the product. In this way, a single extruder can be used to make, for instance, a product with surface characteristics modified by grafting, wire-covering with only a surface layer crosslinked, or heat-sealable crosslinked packaging film.

Abstract: L'invention concerne une méthode de protection et d'aménagement d'un site de disposition de rebuts solides inflammables et/ou désagréables à la vue, telle qu'un amoncellement de pneus.  Selon un premier mode possible de réalisation, la méthode consiste à étendre une membrane de recouvrement capable de couvrir et ponter les espaces vides à même les rebuts sur la totalité de la surface du site ou une portion de cette surface puis à recouvrir cette membrane d'une couche mince de béton ou de terre projeté ou soufflé en place, que l'on peut ultérieurement utiliser comme support pour un aménagement paysager.  Selon un second mode possible de réalisation, la méthode consiste à étendre à même les rebuts sur la totalité de la surface du site ou une partie de cette surface, un matelas mince constitué d'une feuille d'amiante placée en contact avec les rebuts et d'une membrane géotextile ou d'une autre feuille d'amiante disposée parallèlement à la feuille de contact avec les rebuts et reliée à celle-ci à l'aide de fils, puis à remplir le matelas ainsi étanche en soufflant du béton à l'intérieur de celui-ci. Là encore, le matelas une fois installé peut servir de support pour un aménagement paysager.

IPC: C01G28/02
Filed: 1991-04-12
Abstract: ABSTRACT     METHOD FOR FORMING COPPER ARSENATE    The invention provides a method of forming copper arsenate. Copper and arsenic are leached into a treatment solution maintained at a pH level of about 2 to 5 in the presence of at least one impurity.  An oxidant is added to the treatment solution to oxidize the copper and arsenic.  A copper arsenate compound is precipitated from the solution as copper arsenate.  Preferably, the copper arsenate is then releached in a purification solution.  The molar ratio of copper to arsenic is adjusted to a level of at least 2.  The pH of the purification solution is then increased to precipitate copper arsenate having a decreased concentration of said at least one impurity.  Impure copper arsenate may be suspended and reacted in a recrystallization solution preferably having cupric ion.  The pH of recrystallization solution is adjusted to a valve between about 1 and 4.5.
