[Also in Group XXXIII] Light-weight laminated structural materials comprising a core sheet of cellular artificial resin and a cover layer on each side thereof are made by forming, on one or both sides of the core sheet, recesses, coating both faces of the core sheet with a liquid hardenable synthetic resin, and applying heat and pressure or vacuum to the outer surfaces of the cover layers, to combine the cover layers and core sheet and cause the liquid hardenable synthetic resin to penetrate the recesses and harden to form reinforcements rigidly connecting the cover layer or layers and the core sheet. The cellular artificial resin may be made of polymers of styrene, acrylic acid, methacrylic acid, or ethylene, of polyvinyl chloride or vinyl chlorideacetate copolymers, or of cellulose acetate. The cover sheets may be of aluminium, polyvinyl chloride, polystyrene, polyethylene and mixed polymers thereof, cellulose acetate, cardboard or hardenable resins of the same kind as the reinforcements. The hardenable resins may be polyesters, epoxy resins with or without pblyamides or polystyrene. The cover layers and the reinforcements may have embedded in them fibres, fabrics or mats of glass, nylon or asbestos. The recesses may be cylindrical or conical holes or grooves, and may be made on one or both surfaces of the core sheet, and may extend right through it, or only from one-fifth to one-half of the way through. In one embodiment, they form two series of grooves, one on each face, at right angles to each other, and each penetrating halfway through the core sheet. In another embodiment, two core sheets are used, each has recesses on both faces, and they are connected together by an intermediate reinforcing layer of hardenable synthetic resin. Each face of the core sheet may be covered with a fabric or mat sheet provided with holes in register with the recesses in the core sheet, a liquid hardenable synthetic resin is then applied to these fabric or mat sheets to penetrate therethrough, heat and pressure or vacuum are applied to the outer surfaces of the fabric or mat sheets to form the cover layers and cause the liquid hardenable synthetic resin to penetrate the recesses and form the reinforcements. The laminate or its component sheets may be bent or shaped before, during or after lamination. Specification 694,964 is referred to.

Title: Apparatus for heating foundry sand or similar granular material
IPC: B22C5/08
Filed: 1963-11-06
Abstract: 1,018,657. Heating granular material. PETTIBONE MULLIKEN CORPORATION. Nov. 6, 1963 [Feb. 1, 1963], No. 43859/63. Heading F4U. In apparatus for heating pulverulent material, especially foundry sand, scoops arranged on a rotor within a chamber into which the sand &c. is charged continuously pick up the sand &c. from the chamber floor and project it through the flame from a burner. As described, the apparatus comprises a chamber 18, Fig. 2 (not shown), into which the sand &c. to be heated is charged through an opening 34 and screen 64. The chamber has a semicircular base 16. A shaft 70 concentric with the base 16 is supported on bearings on the chamber side walls and carries two spaced discs which on their peripheries carry scoops 20. A burner 22 is mounted to fire downwardly into an offset portion 24 of the chamber 18. In operation the scoops 20 pick up the sand from the base 16 and as the rotor turns some of the sand spills from each scoop and showers down between the discs. The remaining sand is projected through the burner flame into a funnel formed behind a baffle 140 whence it returns to the chamber base to be picked up again by the scoops. Combustion gases are deflected by a baffle 146 into the space between the discs where they further heat the showered sand, whereafter they flow through screens 64, 60 to an outlet 62. When the sand has reached the required temperature a sliding door 130 is opened by a pneumatic actuator 200, 204. This allows a baffle 30 to rise by the action of springs to obstruct the funnel outlet and divert the projected sand through the door opening into a container, not shown. The rotor turns until all the sand has been discharged. The door is then closed, this action automatically retracting the baffle. The actuator may be operated in response to a thermostat sensing the sand temperature.
