Abstract: A finished transformer core (48) includes a core (2) of wound amorphous transformer core material (4) to which rigidifying bonding material (22) is applied to the ends (12, 14) of the core. The bonding material does not cover the entire ends but leaves gaps (24) to permit fluid flow between the ambient environment and the interlamination voids (16) which exist between the layers (18, 20) of the wound material. The core, rigidified by the bonding material, is housed within a fluid permeable containment assembly (28). The containment assembly typically includes fluid permeable filter material (32, 34, 36, 38) which allows transformer oil and air to pass through the material but will trap solid particles of core material within the containment assembly.

Abstract: The present invention relates to an insulation system for a high temperature reactor in which chlorosilanes and hydrogen gases are present. The system described comprises an inner graphite radiant heat shield and an outer carbon-based, rigid, felt insulation of high density. The inner radient heat shield provides increased chemical stability at the hot face in a chlorosilane and hydrogen reactor. Also, the inner radient heat shield reduces the temperature at the interface with the carbon-based rigid felt, thereby reducing the reactivity of the chlorosilanes with the carbon-based rigid felt. The high density of the carbon-based rigid belt further reduces radiant heat loss. More importantly, the high density of the carbon-based rigid felt excludes the highly heat conductive hydrogen gas from the voids of the flet. The insulation system, as described, allows reactors containing chlorosilanes and hydrogen gases to be operated at higher and more efficient temperatures for longer periods of time.

Abstract: Disclosed is a resin mold clutch facing integrally heat molded out of a resin mold base member and a reinforcement member. The resin mold base member comprises a matrix composed of a glass fiber and an aromatic polyamide fiber, an inorganic filler, a solid lubricant, and a resin. The reinforcement member comprises a matrix composed of a glass strand or yarn and at least one strand or yarn selected from a group of rayon and an aromatic polyamide strand or yarn and a binder adhered to said matrix, and is shaped in a spirally wound configuration. Thus the weight of the resin mold clutch facing has been reduced, and its friction and anti-wear properties have been improved.

Abstract: Disclosed is a resin mold clutch facing integrally heat molded out of a resin mold base member and a backup member. The resin mold base member consists essentially of a matrix composed of from 10 to 20 volume % of a glass fiber, from 5 to 30 volume % of at least one heat resistance organic fiber, and from 5 to 25 volume % of at least one heat resistance inorganic fiber, based on the total volume of the resin mold base member, an inorganic filler, a solid lubricant, and a resin binder. In the resin mold clutch facing, the heat resistance inorganic fiber works to suppress the plastic flow resulting from the softening of the glass fiber at a high temperature and under a high bearing pressure. Thus, the resin mold clutch facing comes to have improved and excellent friction and anti-wear properties at a high temperature, and a long life accordingly.

Abstract: A tree guard mat is made from flexible fiber ropes or fibrous strips arranged in concentric rings to form a mat. For installation around a tree, a selected number of inner rings may be removed until a central hole is equal in diameter to the diameter of the tree. In one embodiment, the ends of the concentric rings are joined along a separation radius so that a gap may be created through which the mat can be installed around a tree trunk. The mat is water and gas permeable, and will suppress plant growth around the base of the tree so that trimming is unnecessary.

Abstract: This invention includes a continuous in-plane spiral of monofilament/metallic ribbon which forms a preform for metal matrix composite fabrication. The purpose is to provide continuous spiral filament reinforcement around a hole or central core. This spiral monolayer is fabricated by co-winding the filament and a ribbon or wire made from the intended composite material around a mandrel. Monolayers so constructed could then be stacked to form cylindrical or torus-shaped components and consolidated in a direction parallel to the axis of the shape.

Abstract: A method of effecting practical, simple and economical production of ore-concentrating pads of numerous configurations and sizes. Nails are employed to secure extruded strips to a backing sheet and an underlying support, following which the strips are pivoted about the nails and progressively secured to the backing sheet. The nails are then removed and the resulting pad is vacuum-applied to a concave bowl and adhesively secured therein. The shapes and positions of the strips are such that there is very close sealing engagement beween adjacent strips, after the pad is made into bowl shape, yet there is great elasticity permitting practical vacuum application to the bowl. In one embodiment, the strip-formed pad is used as a mold over which plaster of paris is molded, and the plaster of paris is used as a guide for a tracing machine adapted to make a mold for the mass-manufacture of large numbers of concentrating pads.

Abstract: A polyurethane gripping material for hand held implements. The material is an adhesive backed polyurethane sheet which includes a plurality of small pores on the surface of the sheet. The pores are formed by sprinkling salt on the surface of the sheet while it is in a softened state. The sheet is then cured and sanded down to expose and remove some of the salt granules. Many small pores are exposed by the removal of the salt. The pores act as suction cups to increase the performance of the grip.
