Abstract: A method of and apparatus for drying stored fibrous materials is disclosed. Dry air is injected into a stack of fibrous materials via delivery tube means, and air is withdrawn from the stack via suction tube means. The air withdrawn is then treated so as to remove moisture and cool the air. The cool dried air is then returned to the stack.

Abstract: A buckle for a safety harness consists of two identical parts. Each part comprises a plate 10 having a D-shaped aperture 12 in one end, for receiving a harness, and a portion 14 at the other end folded at right angles to the rest of the plate 10 along an oblique fold line 16. A slot 18 extends half way along the fold line 16. A second plate 20 has a tab 22 welded to the portion 14 of the plate 10 at the side thereof adjacent to the slot 18. The two parts interlock with the upstanding portions 14 and 22 of one part projecting through the slot 18 in the other and vice versa. Tension applied to a harness connected to the apertures 12 tends to draw the ends 24 of the slots 18 into abutment with each other.

Abstract: The invention relates to a folding wheeled chair/luggage carrier of the kind having a pair of side frames which can be folded between an erected, spaced side-by-side position and a stowage position via releasable locking means, and thereafter collapsed fan-wise into a stowage bundle, each side frame comprising pivotally connected back and base support and bracing bars and one or more struts which are pivotally connected between the free ends of said back and base support and bracing bars.A pair of seat bars are pivotally connected at corresponding intermediate positions to respective back support bars of said side frames for pivoting between a stowage position substantially in alignment with said back support bars to a use position in which their free ends extend forwardly, a fabric seat panel being fixed between the seat bars.

Abstract: A clutch or brake assembly in which a hub and reaction member are, in the operative condition of the clutch or brake, coupled together through coupling discs, has one or a plurality of first coupling discs restrained against rotation relative to the reaction member and displaceable relatively thereto axially of the hub, so that it or they can be moved into engagement with one or more second coupling discs, e.g. friction discs, mounted for rotation with the hub to render the clutch or brake operative. The or each first coupling disc is located axially relatively to the reaction member in the inoperative condition of the clutch or brake by a set of spring members mounted directly on the coupling disc through a frictional gripping engagement. Where a plurality of the first coupling discs and a corresponding number of spring sets are used, the spring members of one set interconnect with the spring members of the adjacent set.

Abstract: A simple, relatively low cost system for sealing an ordinary roller shade with respect to the window frame sides, top and bottom is provided. The roller shade seal system essentially comprises a pair of edge seal assemblies in the form of elongate mounting strip members adapted to be permanently mounted to opposite vertical faces of the window frame trim, and a pair of sealing strip members in the form of elongate, generally U-shaped channels adapted to sealably engage the latter edges of the shade, releasably mounted to an associated mounting strip. The window shade sealing system is completed by a shade bottom edge seal comprising a rigid bottom strip reinforcing member, a sill sealing strip and a shade top sealing member.

Abstract: An electrical jumper cable comprising a plurality of spaced metallic conductors is formed from a rigid metallic sheet by selectively reducing the sheet in cross-section so as to define conductor patterns and integral terminal ends, and to render flexible areas of the conductors. The metallic conductors are laminated to flexible insulating films which support the conductors and maintain the conductors in spaced relation to one another.

Abstract: The present disclosure relates to a trimming and/or fin cutting tool for removing ridges, burrs and casting seams of the kind having interchangeable cutting edges, preferably made of hard metal, in which one or more cutting lines of the tool is or are formed by a number of cutting plates (1) detachably mounted on the vertical side (3) of a tool body (2). The tool enables the rational use of the detachable cutting plates and is characterized mainly in that the cutting plates are reversible and are attached to the tool body (2) in a plane directed in the working direction of the tool, the cutting plates having spaces between them to form gaps (6) for the passage of chips. Preferably, the cutting plates along the or each cutting line are attached to the tool body (2) in rows at different heights relative to a base, the separate effective cutting edges of the cutting plates (1) along a common cutting line being arranged to overlap each other.

Abstract: Relatively monochromatic soft X-rays at 4.5 m.mu. is used to induce auger electrons from the silver-halide crystal to sensitize the photosensitive grain, and the exposed crystal is developed into a fine silver grain. The pattern of the silver grains with sizes of about 0.02.mu. can be used as a photoresist with a resolution of about 0.1.mu.. The silver grains can also be used to initiate certain organic compounds for the resist, also with a resolution of the order of 0.1.mu..

Abstract: The present invention concerns a miniature stepping motor 10 for a watch movement comprising a rotor 12 and a stator 11 pierced with a circular opening in which the rotor is located. A reinforcing band 18 surrounds the rotor concentrically and is pressed into the circular opening of the stator. This band 18 consists of a hollow cylindrical part 19 and an annular part 20 which closes at least partially the tubular piece constituting the band 18. A central opening in the annular part 20 provides a housing for the bearing 16 of the rotor axle.This band ensures a double function: that of making the stator rigid and that of centering the rotor.

Abstract: Hollow fiber fluid fractionation cells such as used in artificial kidney machines are manufactured by placing a series of half sections of the longitudinal walls of the cell on the periphery of a winding wheel; winding fluid-filled permeable hollow fibers thereabout until the section is full or slightly over-full; placing another mating half shell over each fiber-filled section on the wheel and assembling the cell core; cutting the courses between each section and draining the fluid therefrom; putting an initial fluid potting compound about the courses of fibers and centrifugally casting the potting compound about the fibers at each end of the cell; cutting the fibers at each end within the area of the potting compound to re-expose the hollow cores thereof and placing end caps on and affixing them to each end of the cell to complete the assembly of the cell.

Abstract: An adjustable card box to hold a multiplicity of the slide-type bingo cards in an upright viewing position and in a manner such that they can be rapidly flipped through comprises two trays, one of which fits and telescopes within the other. A finger-operable locking means serves to lock the position of one tray with respect to the other to permit expanding and collapsing of the space encompassed by the trays to facilitate storage of the box and to permit a player to accommodate the number of cards he wishes to play. The card box has front and rear upward extending flaps pivotedly mounted to the sidewalls, which in the open position serve to support the cards in the viewing position. The flaps can be folded down into the box flat to permit storage of the box and carrying of a vertical stack of playing cards on the box.

Abstract: A method and device are described for measuring a change in the mechanical state aiming at detecting the disturbance the change in state has on a magnetic flux (.phi.). This flux is brought to flow through at least a part of the body (1) under the influence of a driving magnetizing force (H.sub.0).In order to achieve an unambiguous measuring result the average length (l) of the magnetic circuit is kept constant and independent of the change in the mechanical state. The flux (.phi.) consists partly of a main flux (.phi..sub.0) having a definite direction and being of such a magnitude that the magnetic properties of the body depart from the region of irreversibility and partly of an alternating, gradually vanishing flux (.phi..sub.v) superimposed upon the main flux. The alternating flux must have such an initial magnitude that saturation is obtained in both directions of the alternating flux (.phi..sub.v). After the vanishing of the alternating flux (.phi..sub.
