Title: Reinforced abrasive wheels and process for making same
IPC: B24D5/04
Filed: 1964-04-27
Abstract: <PICT:1056543/C4-C5/1> An abrasive wheel is edge-hardened by applying to at least one side face of the wheel a thin sheet of a heat-softenable plastic material, heating the wheel and the sheet to a temperature at which the plastic material is softened to a pressure-flowable state and, while the wheel and the sheet are so heated, applying pressure to the sheet to force the plastic material into the wheel face, thereby to provide a plastic-impregnated zone of substantially uniform depth contiguous to the wheel face.  An abrasive wheel 11 having fused alumina grains and vitrified ceramic bond, intended for crank-shaft grinding, is slowly heated to about 350 DEG  F. and placed in a press having heating blocks 15, 16 and platens 17, 18 with a sheet 13 of 0.03 inch thick polyvinyl butyral in contact with each face.  After the sheets become flowable, pressure is applied through compression pads 14 forcing the plastic into the faces to give a zone having a substantially uniform depth of about 1/16 inch.  The wheel is removed from the press, excess plastic removed from the arbor hole and periphery, the wheel placed in an oven at 350 DEG  F. for approximately 16 hours to cure the plastic, and the wheel slowly cooled.  Other plastic may be used, e.g. phenolic resins and modified phenolic resins; polyester resins; polystyrene; polyurethane; acrylic resins; other vinyl resins such as polyvinyl chloride and polyvinyl acetate and copolymers of vinyl chloride and vinyl acetate as well as copolymers of either of them with other vinyl compounds such as vinylidene chloride, and methacrylate resins. Plastics may be used which harden due to loss of plasticizer at raised temperatures.  Where the mass of the wheel is sufficiently large the wheel is heated to somewhat above the required temperature before the plastic sheets are applied, and a heated press is not used.  Local heating, e.g. with heat lamps, may be used to heat a face of the wheel and a sheet thereon.  The compression pads 14 preferably have a Shore durometer hardness of approximately 50 and may be of corkboard, felt or sponge rubber. To prevent the pad from sticking to the sheet, a coating on the pad or a separate intervening sheet of a silicone compound or a fluorocarbon resin may be used.  A number of thin sheets may be used instead of a single sheet.  The thickness of the plastic-impregnated zone on one face may be different from that on the other face and different plastic may be used for the opposite faces.

Abstract: 689,368. Transformers with inductances. BRITISH THOMSON-HOUSTON CO., Ltd. July 25, 1951 [July 28, 1950], No. 17642/51. Class 38 (ii). A high-frequency electric transformer comprises a unitary body 3 of insulating material, having high dielectric strength and a low loss factor, arranged about and between the primary and secondary windings 1, 2, an axially movable metal cylinder 5 being provided close to the insulating body to form an adjustable short circuited winding. The primary winding 1 is formed of a hollow tube through which a cooling fluid may be passed whilst the secondary winding 2 comprises a single turn of sheet metal the insulating body 3 being formed of a material such as polythene by the Schoop gun process, the body being provided with rounded portions 4 to prevent superficial disruptive discharges. An adjustable copper cylinder 5, axially guided through the bore of the insulating body by rods 5a, forms a movable short-circuited turn in order to vary the coupling between the primary and secondary windings. To provide compensation for the alteration in the transformer reactance which takes place when the coupling is varied, and thus to correct the modulation of the circuit in which the transformer is used, a variable indicator is provided, the winding of which is connected in series with the primary winding of the transformer. The variation of the inductor may be occasioned by the use of a movable core which may be caused to move simultaneously with the cylinder 5. In a further embodiment the inductor may be located in an axial extension of the insulating body in which case the variation in the inductor and in the coupling of the transformer may be effected by the short circuited copper cylinder. A further secondary winding may be associated with the inductor winding to form a transformer having a different ratio to that of the transformer 1, 2, the functions of the transformer and inductor then being interchangeable as desired. A cooling member may be attached to the cylinder 5 which cylinder may be made of two telescoping members to afford adjustment in the length thereof.
