Title: Improvements in or relating to stabilising apparatus
IPC: G05D1/04
Filed: 1947-05-15
Abstract: 633,500. Automatic control systems for aircraft &c. SMITH & SONS (ENGLAND), Ltd., S., and MEREDITH, F. W. May 15, 1947, No. 13172. [Class 38 (iv)] Attitude &c.-Apparatus for automatically stabilizing a body in an aircraft against rotation of the aircraft about an axis comprises means for measuring the rate of turn of the body about the axis, means exercising a monitoring control on the bodv in accordance with the time integral of the measured rate of turn to reduce this integral to zero, when the aircraft is making a banked turn, and a gravity-responsive device operating as a monitor in straight flight. The monitors add control signals to the signals ensuring stabilization of the body when the aircraft rolls. The body may be an artificial horizon or a stabilized platform. In Fig. 1, a platform is stabilized against roll by an A.C. voltage generated by a rate-of-turn gyroscope 5 applied through, high-gain amplifier 21 to a motor 19 driving through a gear-box the ailerons 6, the motor also driving a generator 22 to produce an opposing A.C. feedback voltage in series with the amplifier input substantially equal to the rate-of-turn voltage so that the rate of actuation of the ailerons is proportional to the rate of roll. A further weaker signal generated by a gravity, say pendulum, control 7, acts as a level monitor. In making a banked turn the switch 23 is closed to isolate the control 7 and the platform rotated by the handle 50, the aircraft banking at a corresponding rate to nullify this rotation. In this case a further monitor control is exercised through rectifying the amplified rate-of-turn voltage in a circuit 102 and applying it to cathode-coupled Miller integrator valves 110, 111 in push-pull so that a D.C. voltage across the anodes, dependent on the time integral of the input from the instant that switch 112 connecting the anodes is opened, is passed to a ring modulator 104 and an A.C. voltage proportional to the value of this integral at each instant added to the amplifier 21 input. The total integral of the rate of roll of the platform being zero if the platform is maintained level, provides a reliable control of the level of the aircraft during prolonged periods of banking, e.g. in circling an airfield, thereby obviating errors due to lateral acceleration if a gravity control was used instead. The motor 19 and generator 22 are of the two-phase hysteresis type described in Specifications 576,248, 576,249 and 576,351. Specification 617,240 also is referred to.

Title: Improvements in or relating to apparatus for use in the production of spherical particles
Inventor: NYBO SIGURD ANDREAS
IPC: B07B13/11
Filed: 1963-04-03
Abstract: 1,026,643. Separating solid materials. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 3, 1964 [April 3,1963], No.13186/63. Heading B2H. Apparatus for separating non-spherical and spherical particles comprises a base 1 inclined to the horizontal in two directions, means 16 for feeding the particles near an upper region adjacent a fixed guide member 15 shaped so as to change the rolling axis of the particles, which are under the action of means imparting a relative motion between the base and particles in a direction such that the resultant paths of the particles terminate at different positions along the edge of the base according to their amount of out-of-roundness. As shown, particles are directed by a retarding spout of a hopper 16 on to an endless belt 1 which is moved by a variable speed motor 4 in the direction of the arrow C, for imparting a motion to the particles so that they move in parabolic paths down to trays 13 below. The more truly spherical particles fall into trays 13b, 13c and the rough ones into trays 13d, 13e. The belt may be made of metal, rubber, textile, synthetic plastic or paper-covered material, vibrated by a vibrator 17 and adjusted to the desired inclination about hinges 8 and 11a. The guide 15 serves to reorientate particles adhering together in pairs ("doublets") so that they can be conveyed together with exceedingly rough particles by the belt into an end shoot 18. When a vibrating member 21 is employed it serves to separate spherical particles from "doublets" which have escaped the influence of the guide 15, the member being vibrated in the direction of the arrow D to direct spherical particles into tray 13a and "doublets" into tray 13b. Both the guide and belt are connected to earth, the latter by whiskers 14a. In a modification, the guide 15 may take the form of a series of parabolic curves in stepped formation.

Title: Improvements in or relating to apparatus for determining the metal oxide content of an alkali liquid metal
Inventor: HALL WILLIAM BATEMAN
IPC: G01N33/20
Filed: 1958-04-25
Abstract: <PICT:0883632/III/1> <PICT:0883632/III/2> In apparatus for determining the oxide content of an alkali liquid metal, the rate of flow of the metal through orifices in two barriers is compared, one barrier being resistant to corrosion whilst the other is resistant to corrosion by the metal but corroded by the oxide.  As shown, liquid sodium and/or potassium flows under control of a valve 21 into a chamber 37 and then through a perforated barrier 47 of stainless steel and through a further barrier 48 of niobium.  The outputs from the barriers are taken via pipes 23, 24 to electric flowmeters 74, 75 comprising a permanent magnet 68 having two pairs of pole pieces 71, 72.  The voltage induced in each pair of electrodes 81 brazed to the pipes is proportional to the rate of flow.  The two voltages are fed to a recorder.  The oxide content may be determined from the gradient of a graph plotted against time of the difference between the flows divided by the sum.

IPC: B23G1/32
Abstract: 131,944. Curran, C. J. April 23, 1918. Lathes. - In a milling-lathe having a form-cutter and a thread - cutter, the work spindle has a device which serves to return it automatically after completing a threading operation and which also serves to press the work against the form-cutter when recessing with the lead screw disengaged. The workpiece d, Fig. 1, is placed in a chuck f on the spindle a which is rotated by gear h secured thereon and fed axially by a lead-screw g when this is engaged by a segmental nut k. This nut may be operated by hand-lever n but usually it is raised when the cutter 10, Fig. 4, reaches the right depth as determined by a stop, by levers n, q, Fig. 1, a sliding bar t and a stop w carried by the cutter slide. The saddle w<1> is clamped and at the same time the cross slide 12 is moved to bring the cutter into contact. with the work by a hand-lever not shown. After the work has revolved once in contact with the cutter this is withdrawn and a sping y disengages the nut k so that the work spindle a is free to resume its original position under the influence of spring pins 2 carried by gear h and pressing on a washer 5 with ball bearings 6. If the hole in the work is to be reamered, the profile-milling cutter 11, Fig. 4, is brought into line with and advanced into the work, before threading, by moving the cross slide 12 and saddle w<1>. The stop w, which in the second threading operation acts on the bar t, is arranged to make contact with the work d just before the axial movement of the cutter 11 is arrested by a stop 21 so that the spring pins are forced in slightly and the position of the work to the cutter is accurately determined. After introduction the cutters are moved laterally and clamped by the means already described. An ejector rod is preferably provided and actuated by hand or foot as, for instance, described in Specification 126,419. Specification 132,220 also is referred to.

Title: Improvements in and relating to fluid pressure percussive tools
IPC: B25D9/16
Filed: 1931-05-06
Abstract: 387,357. Percussive tools. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G. and SWEETSER, E. H., Scotswood Works, Newcastle-on-Tyne. May 6, 1931, No. 13410. [Class 122 (ii).] In a fluid-pressure-operated tool, the admission is controlled by a flexible diaphragm held at its centre or circumference and arranged in a chamber so as to divide it into two compartments which are alternately put into communication with the inlet and a cylinder end, the exhaust being controlled by the piston overrunning a port in the cylinder bore. In the tool shown in Fig. 1, the valve-chest comprises two parts 1, 2 arranged between the cylinder and handle. The parts have central bosses between which is housed a diaphragm valve which engages an upper flat seat 10 and a lower conical seat 9. Fluid pressure is supplied by a passage 15 to a chamber 13 between the handle and part 2, which chamber communicates through passages 12 with an annular supply chamber 11. On either side of the diaphragm are arranged the compartments 16, 17. The compartment 16 communicates with an annular recess 22 and the forward end of the cylinder. The compartment 17 communicates with a central bore 20 and the rear end of the cylinder. On the piston passing the exhaust port 25, the fall of pressure resulting in either cylinder end actuates the valve and effects the distribution. The diaphragm may be laminated, or corrugated to give it resiliency. The diaphragm may comprise a strip held at its opposite ends so as to permit slight endwise movement. The chest is then provided with slightly concave recesses to form a chamber between them. The chest is arranged longitudinally of the cylinder, one part integral therewith. In a further construction, the valve-chest is arranged at the end of the cylinder, and is supplied with fluid through a valve of the kind described in Specification 382,585 [Group XXIII]. In a construction of this type shown in Figs. 10, 11, the compartments 78, 79 comprise segmental portions, the compartments 79 communicate with the cylinder ends, but the parts 78 are connected by passages 80, 81 to auxiliary ports 82, 83 arranged symmetrically with respect to the main exhaust 84. Fluid supplied from the cylinder to the parts 78 when the piston passes the ports 82, 83 partly balances the valve and accelerates its action.
