摘要： An improved wood patch, in combination with a slot formed in a blemished wooden surface, and apparatus and method of manufacture thereof. The improved wood patch has, where the wooden surface to be repaired is horizontal, three faces: a flat horizontal exterior face, a flat vertical interior face, and an angled arcuate interior face. The patch has both a larger vertical radius of curvature and a larger angle between the flat vertical interior face and the angled arcuate interior face than the slot. Apparatus for manufacture includes a router utilizing a double router bit having a straight cutting edge oriented perpendicular to the axis of rotation of the bit and an angled cutting edge oriented at an angle to the straight cutting edge. Both relative longitudinal and transverse movement between the wood stock and the double router bit are created by the router being installed on a pneumatically actuated pivoting platform attached to a carriage which is engaged to a longitudinal track, with the router having a cam follower which engages a cam having a series of lobes formed in the shape of the curved intersection of the flat interior face and the arcuate interior face of the wood patch. A series of curved scallop-like protrusions are created on the wood stock which protrusions are subsequently removed by a separate cutting blade, mounted on the carriage behind the double router bit. Utilizing the proper cam, an elongated patch may be formed for a longitudinal series of blemishes on a wooden surface.

摘要： A controller for applying sequential compression to a patient's limb includes a variable speed motor connected to a rotary vane pump, and an electronic control circuit to drive the motor at a speed which will in turn drive the pump at a corresponding speed to provide intended output pressure. The controller provides automatic regulation of preset pressure and operates in a fully automatic manner. The controller is contained within a compact housing which can be floor or bed mounted and which has an output connector integral with a unitary manifold assembly for coupling to a tubing set by which sequentially pressurized air is directed to respective compartments of one or more compression sleeves disposed about a patient's limbs.
