Abstract: 1,072,189. Hydrodynamic brakes. WYVERN MACHINES Ltd. Oct. 27, 1965 [Nov. 11, 1964; April 9 1965], Nos. 45885/64 and 15086/65. Heading F2E. In an hydrodynamic braking device for a rotatable member (e.g. of a machine tool), shown in diagrammatic form, an hydraulic vane pump P supplies fluid under pressure from a reservoir F through a fluid passageway controlled by a solenoid operated valve V which is operative to restrict the free flow passageway, a further passageway, in parallel with the first mentioned passageway, being controlled by a restricted flow orifice R and forming an escape passageway between the high-pressure side O and the lowpressure side I of the pump P. When the valve V is shut, the fluid has to pass through the restricted flow orifice R and in doing so a load is applied to the pump which, in turn, applies a braking action to the rotatable member. In an alternative construction no separate restricted flow orifice R is provided and a relief valve is incorporated in the pump P and adjusted to apply a load to the pump when the shut-off valve V is closed.

Abstract: 1277680 Gyroscopic apparatus HONEYWELL Inc 6 Oct 1970 [17 Oct 1969] 47406/70 Heading G1C An attitude sensor comprises a housing 11 defining a spherical chamber in which a spinning body of fluid is maintained in rotation by the injection of fluid through a constant section annular nozzle 20 extending round a great circle of the chamber wall and having diverging walls 22, 23 on opposite sides of the great circle, the injected fluid flowing adjacent the chamber walls as along arrows 33, 32, 39 or 34, 32, 39 before leaving the chamber through one or more annular outlets 35, 36 adjacent the nozzle 20. This drive arrangement is insensitive to rotation of the housing 11 relative to the spin axis of the fluid body about an axis 18 normal to the plane of the great circle. Run-up and initial caging of the fluid body is by injecting fluid through a line 41 to enter the chamber through a portion of the outlet 35. As shown, the spin axis is vertical and initially coincides with the housing axis 16. Inlet nozzle 20 is fed from an annular plenum chamber 13 and includes radial vanes 55 or slots in the walls 22, 23 to prevent precession of the spin axis about the axis 18 if the gyroscope pitches about an orthogonal axis 17. To detect roll angles of the housing relative to the spin axis about the horizontal axis 18, pairs of pressure tappings 50, 51 and (52, 53) Fig. 2 (not shown) are connected to respective differential pressure sensors, the magnitude of the pressure differential between the tappings of a pair being a measure of the roll angle.

Abstract: 1,116,453. Feeding endless conveyers. GREENSIDE MACHINE CO. Ltd. 28 Oct., 1966 [10 Nov., 1965], No. 47607/65. Heading B8A. A loader-conveyer machine comprises a forwardly disposed ramp 2 the lower front edge of which rests on a floor, and an endless chain 14 at each side of the ramp and bearing outwardly projecting flights 19, 20. Each chain is guided at 22, 23, to form a front run along which the chain moves towards the centre of the ramp and an elevating run along which the chain moves up the ramp. As the chains are driven by reversible hydraulic motors 31, material at the front edge of the ramp is moved by the flights 19, 20 to the centre portion 2A thereof and then up the ramp on to a discharge scraper conveyer 3. Pivoted gathering arms 44 at the edges of the ramp are hydraulically oscillated to feed material to passing flights on the chains. The pitches of the flights on the two chains are relatively staggered as they move along the elevating run. The ramp is mounted on beams 37 for pivotal movement by hydraulic ram means between a lowered position in which the ramp front edge engages the floor and an upper position wherein said edge is spaced from the floor. A screw-operated chain tensioning device 33 is associated with each chain guide 23. A shield 11 is provided along the rear edge of each side of the ramp. The outer portions of the ramp are pivoted at 9 to facilitate folding upwardly of the portions after removal of the chains.

Abstract: 1383603 Machine tool control; automatic stop TRAUB GmbH 19 Oct 1972 [26 Nov 1971] 48118/72 Headings B3B and B3T [Also in Division F2] Fluid pressure operated apparatus for adjusting a tool slide of a machine tool, e.g. a lathe, in dependence upon the deviations of a dimension of a workpiece 2 previously machined on the machine tool from a reference dimension comprises, a measuring sensor 1 for determining the deviation of the workpiece, a screw spindle drive incrementally displacing the tool slide and operable in both directions of rotation through a releasable coupling 12 and a pivot mechanism 11, and pressure fluid control valves 4, 5 selectively controlled by a deviation responsive controller 3, 62, 63 to allow pressure fluid flow from a pressure source 6 to the drive 11 and coupling 12 for displacing the tool slide. The controller 3, 62, 63 classifies the dimension of the just machined workpiece 2 relative to the desired rating D. Measurements in C and E rate plus or minus one increment of adjustment of the screw spindle drive, those in B and F rate plus or minus two increments, and those in A and G automatically stop the lathe. A function controller 63 controls the valves 4, 5 accordingly. In the incremental rotary drive of the adjusting screw spindle 21 the coupling 12 includes fluid pressure operated radially movable members 30, 31 that engage on the inner surface of a drum which is attached to the screw spindle 21. The coupling members 30, 31 are mounted on a body attached to a pivot member 47 which is rocked by the fluid pressure operated drive 11. A throttle 10 in the supply lines 8, 9 ensure a delay between the operation of the coupling 12 and rocking drive 11 so that, depending on which is operated first, clockwise or anti-clockwise rotation of the screw spindle 21 is effected. Backlash in the spindle 21 drive is achieved by disc springs 23 and a disc 22 having radial indentations which engage a catch 25 to prevent rotation of the disc 22.
