Indexing. - A circular dividing plate for machine tools &c. comprises a number of elements of exactly the same length arranged end to end on a circular plate. The elements may consist of balls 1 located in a groove 2 of a plate 4 having a hub 7 for mounting on the machine. The balls are selected from a large number so as to ensure their being of exactly the same size and the width of the groove is the same as the diameter of the balls, the diameter of the groove being selected to accommodate the required number of balls without clearance. The groove is first formed in a lathe so as to accommodate all the balls except one and the remaining space between the last two balls is measured to determine the final diameter of groove required, the depth of the groove being measured by a micrometer as shown in Fig. 2. The groove is then finished in the lathe and the balls introduced with a slight pressure and retained in place by radial stays engaging the hub 7 while they are being secured by metallic cement, solder or thermal expansion of the plate. The machining of the groove is performed after the other machining operations of the plate, all the operations being performed with the same setting on the lathe face-plate, the latter being removed, if necessary, from the lathe for measurements to be made. Rollers may be used instead of balls and may be cylindrical or frusto-conical, the shape of groove being selected in each case so as to provide generators on the rollers which are parallel for engagement with the dividing finger. The elements may be arranged on the outside of the groove and cuts or recesses may be provided on them for enabling the divisions to be seen.

Filed: 1938-11-05
Abstract: 524,801. Direction and turn indicators for aircraft. KOLLSMAN, P. Nov. 5, 1938, No. 32093. [Class 97 (ii)] A direction indicator for aircraft includes a turn responsive instrument incorporating a vane system mounted on a shaft and so proportioned to a flow director that, during a turn, the vanes are rotated by the flow through an angle bearing a fixed ratio to the turn angle, and the shaft drives, through reduction gearing having a ratio the inverse of the first-mentioned rates, a shaft coupled to the indicator drive unit. For navigation purposes, a magnetic compass co-operates with the direction indicator. As shown, the vane system 25<SP>1</SP> mounted on a shaft 26 is situated in a fluid chamber 10. A rotor 19 maintains a circulation of the fluid through guiding surfaces 24, in a direction radially of the vanes, and along the central axis as indicated by the arrows. If the aeroplane turns, the fluid imparts an amplified rotation to the vanes in one direction or the other according to the direction of turn, and through reduction gearing 56, 57 and a magnetic coupling 74, 75 maintains a driven shaft 71 stationary in space. The shaft 71 acting through gearing 69 rotates a directionindicating pointer 63 as the casing turns relatively to the shaft. The rotor 19 is driven by a turbine rotor 29 through a magnetic coupling 36, 38 acted upon by a fluid jet from a nozzle 31 produced by withdrawing air through a passage 43. To correct for deviation of initial position after long use, a magnetic compass element 80 is provided to bias the gear 57 to central position. The magnet 80, enclosed in a float 81, is coupled to the shaft 71 by magnets 93 in the manner disclosed in Specification 520,431. The instrument may quickly be reset to magnetic north and south by closing the passage 43 by means of a knob 46 and valve 45, thereby stopping the restraining circulation of the fluid. Specification 503,585, [Group XXVI] also is referred to.

A wind power plant with variable-pitch vanes embodying means for increasing the starting moment comprises an initially stressed spring which is adapted to swing the vanes, when at rest, through a small angle about their axes and means operatively associated with said spring for additionally stressing the latter, which means is actuated by the running plant. The vanes 2 of a wind motor are displaced when its normal speed is exceeded by a governor 11 acting against the influence of a spring such as a spring 15, Fig. 1. The spring 15 acts on the vanes through a rod 12, a connecting star 13 and push rods 14. A device 17 for holding the vanes in the starting position comprises a spring 18 which is initially stressed to counteract the force of the spring 15. When the wind motor is rotated it drives an oil pump 23 thereby feeding oil to the device 17 and comprising the spring 18 to permit the vanes to move into the operative position. In the embodiment of Fig. 1 the rod 12 is connected to the piston rod 19 of the device 17 by a lever 16 and a hydraulic relay 26 is incorporated in the pump circuit to permit the spring 18 to turn the blades into the starting position at an accelerated speed. A baffle plate 36 controls a discharge valve 35 in the member 17 thereby permitting the spring 18 to adjust the vanes in accordance with the wind velocity. The wind motor drives an electric generator 9 through the gearing shown. In the embodiment of Fig. 4, an oil outlet is disposed in the supply line of the device 17 and is controlled by a member 40 responsive to the speed of the governor 11; the arrangement being such that the port is uncovered when the normal speed of the motor is exceeded to permit the spring 18 to influence the vanes 2 accordingly. The member 17 has one or more ports 41 which limit the stroke of the piston 20 and communicate with the oil sump 42 feeding the wind wheel bearings. An additional control member responsive to a baffle plate is likewise incorporated in the embodiment of Fig. 4; the baffle plate being actuated by wind pressure, by hand or, in so far as the wind motor of Fig. 4 drives a piston water pump, a float.
