Title: Improvements in or relating to lathes
IPC: B23B3/28
Filed: 1953-03-02
Abstract: 755,935. Lathes. PROGRES INDUSTRIEL. March 2, 1953 [Jan. 8, 1953], No. 5744/53. Class 83 (3). Work feed-and-discharge apparatus for a lathe comprises' a rotatable cradle to receive workpieces from a feed ramp and to deposit machined workpieces on a discharge ramp, including a pusher operable to move each workpiece in turn into a centred position in the lathe for machining and thereafter return it to the cradle member, means being provided to reciprocate the pusher and to effect intermittent rotation of the cradle. The workpieces 16, Fig. 11, which may be shells, are fed down an inclined ramp 36 to a lift 40 operated by a hydraulic piston-and-cylinder 43, 44. The lift raises each workpiece to a delivery device 41, from whence it rolls on to a cradle 39 which rotates, due to the weight of the work, when a pawl 68, Fig. 9, is withdrawn from a ratchet 66 on the end of the shaft carrying the cradle. The pawl 68 is released by a trip on the lower end of the lift. The workpiece is brought, by rotation of the cradle, into position for feeding to a turret 2, Figs. 1 and 2, the turret axis being offset from the lathe centre but parallel thereto. A hydraulically-operated feed rod 4, Fig. 4, passes through the centre axis of the turret and a feed member 15, rotatable between collars secured to the rod 4, has projections 14, 15, which enter the passage 3 and engage the work. The turret is automatically rotated to bring the work into line with a gripping-device (see below), on the lathe spindle, the rod 4 then moving to slide the work into position for turning. The work is now free of the turret which continues intermittent rotation, firstly to bring a centre-drill 30, Fig. 7, and facing-tool 31, on the turret, into working operation, and secondly to bring up a centre 34, Fig. 2, also on the turret, to support the work during the outside turning operations. On completion these operations are reversed, the work after release from the gripping device being retracted through the passage 3 to the cradle 39 where it falls to the lower discharge ramp 37, Fig. 11. Chucks; gauging-devices. The gripping-device comprises interval jaws 17, 18, Fig. 3, operated by wedges 26, 23, moved in opposite directions by members 27, 22 respectively. The latter are hydraulically-operated and may operate automatically when the work is pressed against a stop 19 connected to a valve. The stop is adjustable and may act as a dead stop only.

Title: Improvements in helicopters
IPC: B64C27/59
Filed: 1944-03-29
Abstract: 580,109. Helicopters. CIERVA AUTOGIRO CO., Ltd., and PULLIN, C. G. March 29, 1944, No. 5789. [Class 4] A helicopter provided with a " torsional flapping " lifting rotor, i.e. one in which the blades are mounted for flapping movements and the pitch angle varies with and is uniquely dependent on the flapping angle, comprises a rotor mounting and control mechanism including a non-rotary, rotor hub-supporting member which is bodily displaceable without tilting relatively to the airframe, in one or more directions substantially perpendicular to its axis, and a control circuit for displacing the said member in one or more of said directions. In the form shown in Fig. 1, the rotor hub 31 is supported by a non-rotary tubular member 68 provided at its lower end with a flange 69 engaging a slot in a ring member 72, and displaceable in any direction by means of a universally mounted control member 77. The transmission includes an intermediate telescopic shaft 98 connected to the output shaft 95 and drive shaft 100 by universal joints. Fig. 4 shows an embodiment in which the rotor hub is bodily displaceable only in the fore-and-aft direction by a screw jack 103 operated by the control member 77 through a sprocket 106 and pulleys 108. The hub 31 is mounted on the displaceable member 33 by gimbals, and is tiltable in any direction by the control 77, the tilting and displacement effects being additive in the pitching plane. Fore-and-aft trimming is effected by the mechanism shown in Fig. 6, interposed between the sprocket 106 and a bell-crank 118 in the hub tilting mechanism, to vary the datum setting of the sprocket' 106 and screw jack 103 in relation to the control member 77 and lever 118. The mechanism comprises coaxial shafts 120, 121, connected through bevel pinions 125, 126, 127, mounted in a cage 122. Normally, the bevel pinions operate as a simple reversing gear, but by pressing a hand wheel 137 towards the cage a dog-coupling 135 is disengaged enabling the cage and pinions 126, 127 to be rotated by the hand wheel to vary the datum setting. According to a third embodiment, Figs. 7 and 8 (not shown), the rotor hub is mounted on parallel links permitting bodily displacement in any direction under the control of a main control member, and tilting of the hub is also permitted under the control of an auxiliary trimming lever. Specifications 393,976, 471,820, 567,989, 569,724, and 572,909 and U.S.A. Specification 2,004,310 are referred to.

Title: Automatic control apparatus
IPC: G05D1/04
Filed: 1945-03-09
Abstract: 617,240. Automatic control systems. SMITH & SONS (ENGLAND), Ltd., S., and MEREDITH, F. W. March 9, 1945, No. 6004. Drawings to Specification. [Class 38 (iv)] In an automatic control system for aircraft in which deviations from an existing course are counteracted by a rate-of-turn gyro, the course is changed by selecting an angle of bank and controlling the rudder by a signal which is the difference between signals proportional respectively to the rate of turn and to the tangent of the angle of bank. The signal becomes zero when the craft is turning at the correct rate at the cruising speed. At other speeds, side-slip takes place and a device responsive to such slip corrects the turning rate. Alternatively, the signal proportional to the tangent of the angle of bank may be adjustable in accordance with the actual airspeed. Means are provided also for automatically correcting roll and pitch, for selecting a desired normal pitch angle and for controlling the course by a compass jointly with the rate-of-turn gyro. The gyro may be replaced by the rate-of-turn devices described in Specification 611,005, [Group XX]. Specifications 576,248, 576,249 and 576,351 also are referred to.
