Abstract: 1,011,584. Radar displays. DECCA Ltd. Feb. 28, 1963 [Nov. 30, 1961], No. 42959/61. Heading M4D. In radar P.P.I. display apparatus of the type wherein the rotating radial scan is produced by a rotating coil 13, additional, orthogonal deflection coils 20 and 21 are provided, fed with repetitively varying signals between successive radar display scans or whilst the normal radar display scans are suppressed, to produce a marker trace on the screen of the C.R.T. 12. The repetitive signals are sinusoidal and are produced by the secondary windings 22 and 23 of a magslip 24, having a rotatable primary winding 25 fed with an A.C. signal from generators 27 via potentiometer 26. The arrangement is such, as to produce in-phase A.C. signals in the two coils 20 and 21, of relative amplitudes dependent on the angular position of winding 25, resulting in a straight line marker trace of an angular position corresponding to that of winding 25. The start of the marker may be off-centred by biasing D.C. currents supplied by means 29 and 30, which means may be under the control of joystick type control means. When used on a ship it is usual for part of the azimuth scan to be blocked by masts &c. and means are provided comprising a gate control 32, controlled by signals from an antenna bearing data means 14, and operating gates 33, when the blocked off region is reached, to suppress the normal radar signal and supply to scanning coil 13, and to pass the A.C. supplies to the coils 20 and 21, to produce the marker trace. In order that a radial trace and not a diametric trace shall be produced the trace is brightened by the rectified output of source 27 from brightness control means 28. In alternative embodiments the signals feeding coils 20 and 21 may be sawtooth, or manually operated switch means may be provided to display the marker trace in between successive radar scans or to suppress the radar display and replace it by the marker trace. The marker trace may be used to show the relative motion of one target relative to another on a true motion display, on the true motion of a target on a relative motion display. Specification 1,011,583 is referred to.

Abstract: 976,246. Making boxes. INTERNATIONAL PAPER BOX MACHINE CO. Dec. 16, 1960 [May 27, 1960], No. 43315/60. Heading B5D. [Also in Division B6] In a machine for making boxes, such as is described in Specifications 863,346, 876,331 and 888,215, wherein parallel longitudinal creaser bars crease the blanks along the centre lines of outer pairs of slits, the blanks are fed from a stack towards the creasing zone with their slits deliberately disposed in misalignment with the creaser elements, and the centre pair of slits is engaged by registration elements which are moved transversely towards the feed centre line to move the blanks into true registration without stopping the feed of the blanks. The blanks 43, after separation from the stack at 24, are gripped between opposed friction belts 35, 36 and moved towards the creasers 37, 38 beneath the lower run 83 of an endless chain 80. The chain 80 is mounted on drive sprockets 81, and is formed of links 84 to which are pivoted members 85 having lugs with inclined faces. The lower run 83 rests on a blank 43 and travels at the same speed and the same direction, and is supported laterally by side guides: further, the lower run 83 has a portion which is arranged to be displaced bodily by a spring 103 when a push rod 102 is reciprocated longitudinally by a rotating cam 111. The rod 102, which comprises several sections joined together by universal joints, is connected by bell-crank levers 100 to pivoted links on the lateral guides for the lower run 83 of the chain 80, so that the spring 103 can cause lateral movement of the run 83. When this occurs, some of the members 85 move across the blank 43, enter the centre slits of the blank, and move the blank transversely into registered position. The blank is then creased longitudinally along the lines of the outer pairs of slits by the creasers 37, 38.

Abstract: 1,023,739. Hydrodynamic torque converters; change-speed control. FORD MOTOR CO. Ltd. Oct. 28, 1964 [Dec. 6, 1963], No. 43891/64. Headings F2C and F2D. In a hydrodynamic torque converter 96 having an engine-driven impeller 100, a turbine 112 which drives an output shaft through a planet gear (not shown) and a reactor 130, the turbine 112 and/or reactor 130 are axially movable and the blading arranged so that the axial thrust produced is proportional to the converter ratio and engine torque. The axial movement of the turbine 112 and/or reactor 130 acts on a pilot valve 148 to throttle the converter supply and produce a back pressure in the duct 172 which is used to effect ratio shift in the planet gear. As shown, both the turbine 112 and reactor 130 are axially movable. The turbine 112 is splined at 122 to a shaft 124 which drives the planet gear whilst the reactor 130 is splined at 132 to the outer race 134 of a one-way detent, the inner race 136 of which is splined to a stationary sleeve 140. The axial movement of the turbine 112 and reactor 130 act through a bearing 156 on an annular piston 154 which controls the flow of fluid through an orifice 164 in the converter supply. The back pressure developed in the duct 172 acts on a pressure regulator valve 194 and shift valves 190, 192 to effect ratio shift in the planet gear and to regulate the pressure supplied to the ratio establishing servos. Pressure fluid is supplied from a pump 180 through a restrictor 186, ducts 184, 172 and orifices 166, 164 to the working circuit of the converter. To prevent overheating of the converter fluid when the orifice 164 is restricted, a by-pass supply may be provided from a converter pressure regulator 202 through ducts 178, 162. In Fig. 1 (not shown), only the reactor is movable axially. In Figs. 1, 3, 4 and 5 (not shown) the converter by-pass supply is omitted. In Fig. 4 (not shown) the back pressure line which acts on the shift valves and also supplies the pressure fluid for operating the ratio establishing servos. In Fig. 5 (not shown) only the turbine is movable axially. Fig. 6 (not shown) is a graph of the axial thrust produced by the turbine and reactor against engine speed under converter stall conditions and Fig. 7 (not shown) is a graph of turbine or turbine and reactor thrust against converter ratio at full throttle.

The centrifuge head 120 consists of circular plates 126, 130 fixedly secured to a shaft 128 having a bore 128" for rotatably receiving the end of the driven shaft 154 and a depending extension 128' Which bears on a support 132 secured by a set screw 127 to the shaft 154. The gear 134 is mounted on a collar portion 192 of the support 132 and carries a pin 142 which engages in a circular slot 144 in the plate 126. The tube holders 136 are mounted on shafts 138 passing through openings in the plate 126 and carrying the pinions 140 which mesh with the gear 134. The drive motor 156 is reversible and may be connected to the shaft 154 directly or, as shown in dotted lines in Fig 2, via a belt drive 141. A timer 124 operating through switches 184, 186 and relays 184", 186" automatically controls the rotation of the centrifuge head through a sequence of four cycles, e.g. of 45 seconds duration (during which centrifugal force greater than gravity force is applied to the blood samples) and also controls the reversal of the motor 156 and rotation of the sample tubes 150 for 180 about their own axes between each cycle and application of centrifugal force. The pin and slot 142, 144 also serve to restrict the rotation of the sample tubes about their own axes to periodic during which the centrifuge head is at rest or begins its rotation.

Abstract: 1,197,939. Vibration dampers. GENERAL ELECTRIC CO. 3 Oct., 1967 [9 Dec., 1966], No. 44925/67. Heading F2S. A vibration damper, particularly for use in a gravity-free environment, consists of an inner (preferably generally spherical) assembly 12 connected to means such as a rod 14 attachable to the body to be damped and an outer assembly 22 surrounding the inner assembly and fitted with an array of magnets 24, 26, 28. The inner assembly includes a diamagnetic (e.g. pyrolytic graphite) element 43 and a conductive (e.g. copper) element 42, so that the inner assembly is repelled by the magnets of the outer assembly and at the same time is damped by eddy current effects when there is relative movement between the two assemblies. The conductive element may be anisotropic so that the damping effect is different in different directions. The magnets -as shown in Fig. 2, which is a view from above Fig. 1-are so disposed that they produce a net magnetic field in the direction of arrow 29. Thus, though the magnets uniformly repel the inner assembly, the device as a whole has a net external magnetic moment. The effect of this is that extraneous ferro-magnetic particles will become attached to the exterior of the device and not enter opening 20 in the device to disturb the internal equilibrium. A ring magnet 30 fitted adjacent the opening 20 may be employed as an additional safeguard in this respect.

Abstract: 1,267,709. Shoe drum brakes. NORTH AMERICAN ROCKWELL CORP. 16 Sept., 1969 [12 Nov., 1968], No. 45478/69. Heading F2E. In an automotive vehicle brake assembly including an automatic brake shoe adjustment mechanism having a rotatably mounted actuator member 49 provided with a toothed periphery 56, there is a one-piece retainer 64 having a slotted portion 73 for non-rotatably receiving a brake shoe 14 and opposed arms 68 reversely bent to form substantially U-shaped, resilient clips adapted to extend around the toothed periphery of the member 49, each clip being shaped to provide an internal detent 72 adapted to be interlocked with the toothed periphery, whereby the retainer operatively prevents rotation of the member during automatic adjustment while permitting selective rotation for manual adjustment. As shown, brake shoes 14, 15 are displaced outwardly to engage a brake drum by a fluid-pressure operated reciprocable rod 31 carrying a wedge disposed between rollers 33, 34 extending in the grooved ends 35, 36 of plungers 23, 24. Rotation of the plunger 24 is prevented by a pin 41 coacting in a slot 39 in the plunger, and the plunger 23 slidably mounts a member 46 internally screw-threaded to receive the member 49 and formed with spiral ratchet teeth 51 engaged by ratchet teeth 52 on a spring-loaded pin 53 slidable in a bore 50. During brake operation, plunger assembly 23 is displaced outwardly and member 46 moves relative to pin 53, whereby if the displacement is greater than the pitch of the teeth 51 on the return stroke, ratchet action of the teeth 51, 52 results in rotation of the member 46 and consequent relative rotation between that member and the member 49 to produce automatic length adjustment of the plunger assembly.
