  • Heating instrument for treating a deformed nail
    Patent number: 4702246
    Abstract: Pliers are disclosed for the treatment of ingrowing nails on the human body. The pliers comprise first and second jaws. The upper jaw has a support member on which there is mounted an electrical heating wire. A slot in the lower jaw is adapted to receive the support member and wire.In use, the pliers grip are ingrowing toe nail, and an electric heating current is applied to the wire, to cause local heating of the nail. The nail thus softens, and can be bent back into better shape, which shape is retained upon subsequent cooling of the nail. The lower jaw is of a relatively great heat mass, so as to ensure that no undue heating of the nail plate occurs. Control circuitry is provided for controlling the heating current through the heating wire, optionally in dependence upon a detected temperature.

  • Characterizing and handling multi-component substances
    Patent number: 4701838
    Abstract: A method of handling, as bulk material, a substance which is one member of a class of multi-component substances includes subjecting successive test samples of the substance to a series of measurements which provide multiple data points which are influenced by at least one selected parameter and from which are determined the factor loadings for the respective test sample of each of multiple pre-determined abstract factors. Pre-determined regression coefficients are utilized to calculate from the factor loadings a predicted value for the selected parameter for the respective test sample. The predicted value is compared with one or more related set points, and the constitution and/or disposition of the substance is controlled in response to the outcome of the successive comparisons.

  • Chucks
    Patent number: 4700955
    Abstract: A fluid-operated ram, for example comprising a cylinder 10 and piston 12, is provided for actuating a device such as a chuck having jaws 15. When the jaws are moved by the ram to grip a workpiece this constitutes a limiting position which impedes the flow of fluid thus causing a build-up of fluid pressure within the ram. This build-up can be detected to give an indication as to when a workpiece has been securely and safely gripped. To ensure that a false indication is not given if the ram reaches an end of its working stroke before the workpiece is securely gripped, means (22) are provided to relieve pressure within the ram when the ram reaches an end of its working stroke.

  • Automatic transmission for multi-speed bicycle
    Patent number: 4701152
    Abstract: An automatic transmission for a linked chain driven wheel includes a plurality of chain-engaging sprockets disposed coaxially with and spaced apart along the axis of rotation of the wheel. Each of the sprockets has a predetermined diameter which differs from that of the other sprockets. The sprockets are drivingly connected to the wheel. A chain guide, which is axially movable relative to the sprockets, is provided. The chain guide, when aligned with a given sprocket, will guide the drive chain into engagement with that given sprocket. A chain guide actuator is operatively connected to the chain guide for varying the axial position of the chain guide automatically in response to the angular speed of the wheel.
