Title: Improvements in or relating to automatic or semi-automatic telephone or like systems
IPC: H04Q3/00
Filed: 1933-11-24
Abstract: 429,130. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., HARTLEY, G. C., and BRAY, F. H., 63, Aldwych, London. Nov. 24, 1933, No. 13487/34. Divided out of 418,787. [Class 40 (iv)] At an incoming selector stage, an idle bypath control circuit is seized over additional wipers of the selector itself by a preliminary hunting operation. The bypaths are multipled as many times as possible in the selector banks in order to minimize the hunting time. Hunting is initiated when line relay LS energizes over the incoming junction, and TS energizes in series with BT in an idle bypath and connects up KS which extends the loop to line relay A in the bypath. Relays B, D, BE pull up and BT falls back. The first numerical digit sets the switch IR1 and IR2 moves to the position marked thereby and hunts for an idle bypath of the next stage. Relay H energizes and extends the loop, a discriminating signal being sent forward if the received digit is even. Relay X operates, seizing the common marking multiple and releasing TS. The switch IR1 hunts for the selector IS, whereupon T, TT, GS pull up, and the selector then advances to the position marked by IR2. Relays M, G pull up and switching relay HS extends the loop to the normal line wipers. The bypath remains held until the subsequent bypath becomes associated with the seized selector of the next stage. If all the incoming bypaths are busy, the first impulse received by line relay LS connects up GS which sends back a busy signal.

Abstract: 1308768 Cathode-ray tubes MOTOROLA Inc 6 May 1971 [22 June 1970] 13522/71 Heading H1D A luminescent screen for a CRT is formed by settling phosphor particles from a solution and rotating the tube about an axis parallel to and spaced from the tube axis whilst decanting the supernatant liquid using relatively vibration free tilting means so that the liquid washes the entire coated area to redistribute the settled particles. A phosphor suspension is formed by mixing CaMg silicate containing Ce, deionized or distilled water and a gelling agent, e.g. Ba acetate or nitrate, Na bicarbonate or NH 4  carbonate. The suspension is elutriated twice to obtain particles within a desired range. Na or K silicate binder is added and the mixture again elutriated A C.R.T. is covered with the resultant suspension and a phosphor layer settles out, the screen being kept 10-20‹ F. warmer than the suspension. The screen is tilted to remove the supernatant liquid and rotated. Particles and small aggregates are thereby moved into spaces between large aggregates resulting in a more uniform deposition. The screen may be rectangular; the phosphor particles less than 5 Á.

Abstract: 164,950. Eddy, E. D. May 17, 1920. Wet - separating. - Stock comprising different qualities of grain or mixed with weed, seeds, chaff, smut, &c. is separated in a liquid such as a solution of sodium nitrate subjected to centrifugal pressure the density being fixed according to the separation desided. A solution of 40-50 parts by weight to 100 parts water is stated to be suitable for seeds weighing about 601b. per bushel. The container, which is mounted on a tripod, comprises parts 11, 12, with flanged edges bolted together embracing a spider 14 having a centre-bearing 15. A rotor C with an annular flange 21 is journalled on the bearing, and its upper portion projecting beyond the nut 16 which engages with the shoulder 18 is provided with bevelled gear 17. The rotor may be driven by moans of a belt pulley or a hand crank. The conduit 19 has peripheral outlets 20, the size of which may be varied (by inserts 33) to suit different grains. Vanes 22 and baffle walls 23 are arranged as shown in horizontal cross-section in Fig. 4. The inlet conduit 25 has a valve 26 and guide plate 27 and when the rotor is rotating at a predetermined speed sufficient liquid is introduced to maintain a flow from the discharge conduit 24 whilst the valve 32 is open. The stock with a proportion of liquid is delivered to the conduit 19 and discharged through the openings 20, any air enveloping the seed being liberated owing to the centrifugal agitation of the liquid which assumes the form of a hollow cylinder. The heavier grain is carried outward to the casing and then forced downward under the influence of gravity and the current to the outlet 32. The lighter grain is forced to the inner surface of the liquid cylinder and is discharged through the outlet 24.

Filed: 1963-04-05
Abstract: 1,032,804. Torsional vibration dampers. HOUDAILLE INDUSTRIES Inc. April 5, 1963, No. 13712/63. Heading F2S. A torsional vibration-damper comprises a rotatable hub having radially outwardlydirected surfaces, at least one inertia member, extending radially from the hub and having an arcuate surface in rocking engagement with the hub, spring means urging the inertia member radially inwards against the hub and into a radially erect position and means carried by one of the foregoing to damp the rocking of the inertia member. Fig. 2 shows an embodiment in which the surfaces 31 of the hub 21 are in the form of a right prism upon which four convex elliptical surfaces 22a to 25a (part in Fig. 2, not shown) of the inertia members 22 to 25 rock. The spring consists of metal cables 33, 34 which are retained in a channel formed between spaced flanges 32 around the outer arcuate surfaces 22b to 25b of the inertia members by fittings 35, 36 melted on to anchors 38 on the inertia member 22. Balls 50 locate the centres of the surfaces 22a to 25a on the surfaces 31. An arcuate plate 40 with a number of friction elements 41, 42 secured to it by rivets is urged against the underlying inertia members by springs 46. The damper is attached by bolts 29, to a rotating shaft 30. Oscillations of the shaft 30 are imposed on the damper whose inertia members with the spring 26 will attempt to oscillate with it but will, due to the frictional drag of the elements 41, 42, rock out of the radially erect position with a lag which opposes the angular vibrations of the shaft 30. Other embodiments are illustrated in Figs. 8 to 18 (not shown).

Title: Sensor for sensing changes in the rotational speed of a  rotatable member
IPC: G01P15/02
Filed: 1972-03-24
Abstract: 1330607 Accelerometers TELDIX GmbH 24 March 1972 [25 March 1971] 13970/72 Heading G1K A sensor for sensing changes in the rotational speed of an axle 3 (or wheel hub) comprises a flywheel mass 5 in a housing 1, 2 rigidly connected to the axle 3 and constrained by a force to rotate therewith, but movable relative thereto to a limited extent against the constraining force in response to a change in the rotational speed of the axle 3 and a viscous damping fluid so arranged in the housing that its damping effect is substantially unaffected by changes of temperature. Springs bias two levers 8 to hold a pin 12 in the mass 5 centrally in an opening in a plate 7 secured with a plate 6 to the housing 1 so long as the angular speed of the axle 3 is constant. Upon acceleration or deceleration one or other of the levers 8 actuates one or more contacts in sequence to provide an electric signal through leads 10. To avoid response to changes of short duration, the housing 1 is filled with damping oil and the effect of a change in temperature on the damping quality, of the oil is compensated by providing bi-metal strips 4 upstanding from a base 15 clamped round the cover 2 of the housing 1 by a ring 16. As the oil thins with rise of temperature the gap between the strips 14 and the mass 5 is reduced. The periphery of the mass 5 is rounded to match the curvature of the strips 14 when the gap is very narrow and a disc 18 prevents actual contact. In an alternative embodiment Fig.3 (not shown) the housing is only partially filled with fluid which then forms a ring during rotation. With increase of temperature the damping fluid becomes thinner but the fluid expands to increase the area of the mass dipping therein and the two effects may be balanced by suitably selecting the quantity of the fluid and the configuration of the mass. The sensor could be used in a brake control or anti-skid control system.

Abstract: 878,539. Ignition generators. HALDEX A. B. April 22, 1960 [April 28, 1959], No. 14174/60. Class 35. In a flywheel magneto the stator is provided with separate windings on separate cores for ignition, stop lights, rear lights, and headlights, the tail-light being caused to light when the headlight is used, by an armature reaction effect diverting flux into the tail-light core. Cores 2, 4 carrying windings 3, 5 which supply the headlights and rearlights respectively are adjacent one another, and the former has a larger area and a smaller airgap between the poles of the flywheel than the latter. When the switch 6 in the headlight circuit is " OFF " at 9, core 2 has a much lower reluctance than core 4 and very little flux passes through core 4 and only a small E.M.F. is induced in coil 5. In either the dim-light of full-light position of the switch the increased reluctance of core 2 diverts enough flux into core 4 to light the tail-lamp 8. Two further cores 20, 21 coupled by magnetic pieces 22 carry coils 15, 16 for ignition and braking circuits respectively. The area of core 20 is larger than 21 so that a larger E.M.F. is induced in the ignition circuit than the braking circuit. On depression of switch 19 current is fed to the brake light 18 from coil 16 without affecting the ignition voltage.

Abstract: 135,882. Dawson, Sir A. T., and Buckham, Sir G. T. Sept. 4, 1918. Recoil apparatus for high-angle guns. Consists in means for automaticallyregulating the recoil and run-out, so that the effect of the weight of the recoiling parts is compensated for, and an approximately constant length of recoil is obtained at all elevations. This is effected by the provision of a conduit between the ends of the recoil cylinder, and of another communicating with a recess in which a retarding-ram works, there being a valve in each conduit automatically adjusted according to elevations. In the construction shown in side elevation in Fig. 1, and in vertical section in Fig. 2, as seen from the right-hand side of the gun, the non-recoiling brake cylinder A is provided with the conduit A<2> connecting the two ends of the cylinder. A rotary cock a<2> arranged in the conduit A<2> is connected by an external arm a<3> and link A<3> to a fixed part of the carriage at a point some distance from the trunnion axis, so that as the gun is elevated, the cock is rotated and progressively closes the conduit A<2>, thereby setting up a greater resistance to the flow of liquid. The conduit A<2> is additional to the usual valve-key arrangement a, A<1>. The resistance to the run-out is simultaneously controlled, and reduced with the increase in elevation, by a second rotary cock b<2> located in the passage B<2> through the fixed retarding-ram B. This cock is also actuated by the link A', in a similar manner to the cock a', by the parallel-motion links shown in Fig. 1. The invention is also described as applied to recoil apparatus of the recoiling-cylinder type.
