  • Patent number: 4413383
    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.

  • Patent number: 4362227
    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.

  • Patent number: 4352309
    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.

  • Patent number: 4342930
    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.

  • Patent number: 4337861
    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.

  • Patent number: 4335918
    Abstract: In a safety seat installation in a vehicle such as a bus or coach, where the seat is one of a longitudinal row of similar forward facing seats, the back is constructed in two portions 4 and 5 which are pivotally mounted at 3 and 6 respectively. In the event of sudden deceleration, for example in an accident, the rearwardly seated occupant's knees push the bottom of the lower seat back portion 4 forwards so that the top of this portion pushes the upper seat back portion 5 backwards into a position to restrain the rearwardly seated occupant's torso.

  • Patent number: 4316146
    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.
