Title: Improvements in luminescent materials
IPC: C09K11/08
Filed: 1942-06-17
Abstract: 578,272. Luminescent materials. GENERAL ELECTRIC CO., Ltd., McKEAG, A. H., and RANBY, P. W. June 17, 1942, No. 8309. [Class 39 (i)] A luminescent material for use in discharge lamps such as mercury vapour or neon lamps, cathode-ray tubes and X-ray screens, consists of calcium pyrophosphate and an inorganic activator; this may be antimony, tin or samarium, or mixtures of these activators, with or without addition of manganese. Proportion of activator and wave-lengths of exciting energy are given with resulting colour of luminescence. In one process of manufacture, calcium phosphate is obtained from phosphoric acid and calcium carbonate, the filtrate being washed, dried at 150‹ C. and ground ; to this phosphate is added the activating metal preferably as chloride and the paste again dried at 150‹ C. To samples of this dried paste is added ammonium phosphate (NH4)2HPO4 to increase the P2O5 content by 2, 4, 6 and 8 per cent respectively and these samples together with one without ammonium phosphate are heated in air for about 1 hour at 1050-1100‹ C. and then ground. The samples are then tested for luminescence. Specification 512,154 is referred to.

Title: Improvements in or relating to the pelleting of carbon black
IPC: C09C1/60
Filed: 1949-03-29
Abstract: <PICT:0670980/III/1> Flocculent chain structure carbon black is pelleted by continuously introducing the dry black into one end of an elongated unobstructed cylindrical mill at above 175 DEG  F, rotating the mill about its longitudinal axis to form pellets by cascading the black over the bed in the mill, continuously returning one portion of the pellets to the mill inlet and removing the other portion as product.  Carbon black enters pellet mill 11 through spaced openings 33 in fixed central tube 12 by action of helical screw 13 mounted on shaft 14 driven by power unit 15.  The black builds up on the charge of recycled pellets and the resulting pellets are discharged through openings 27, adjustable by slide covers 31, on to large mesh cloth 21 which removes scale discarded at 30.  The pellets passing through cloth 21 are divided into the two portions by mechanism 23, the recycle portion being returned by conveyer 26, hopper 28 and pipe 29 to the mill and the product passing from pipe 25.  The ratio of recycle material to product may vary from 1/2 : 1 to 2 : 1.  Blower 55 forces hot gases at 300 DEG -600 DEG F from heater chamber 52, having burner 53, through pipe 56 into the mill, and gases are returned by pipes 57, 59 or vented through damper 58.  Air is admitted through damper 54 to adjust the gas temperature to 200 DEG -225 DEG F. End plates 34, 34d rigidly fixed on central tube 12 and segment plates 47 on the discharge end of the mill prevent hot gas leakage.  The mill is driven through tyred wheels 36 by power unit 37 at 5-12.5 r.p.m. and is provided with spring-loaded scrapers rigidly attached to the central tube.  The product pellets may be passed to a hardening mill of similar construction to the pellet mill, but without the central feed tube, and rotated at 13.5-16 r.p.m.

Title: Improvements in mechanism for periodically changing displayed matter, in show-cases and the like
IPC: A47F3/08
Filed: 1934-03-19
Abstract: 436,858. Changing signs. TRIPP, E. J., Hillcroft, Stonehill, Hanham, Bristol. March 19, 1934, No. 8516. [Class 3 (i)] In rotating-prism display apparatus in which the prism is retracted from a viewing window to enable it to turn and be brought back to the window to expose another side a torque is applied to the prism which torque effects the retraction of the prism against the tension of a spring by the bearing of a part of the prism against an abutment. The prism b is pivoted at g to an arm e pivoted to a framework at k. A tension spring f connects the arm e to a crank o on a rigid 3-crank assembly j, l, o also pivoted at k. The crank j is coupled by a rod i to a crank m pivoted about the axis g and carrying a pawl h<1> engaging a ratchet h on the prism. The crank l is coupled by a rod j<1> to a bell-crank m<1> actuated by a rotating cam p, the rotation of which is thus transmitted as intermittent impulses to the prism b. The cam p strikes a roller p<2> on the bell-crank ml to initiate the return movement of the crank. The prism b carries at its lower corners rollers d which abut against a rail c on the enclosing cabinet. This rail may be on one side only of the roller d when the action of the spring f is relied upon to bring back the prism to the window, but a rail enclosing the roller front and rear may be provided to effect positive return of the prism. A dash-pot may be introduced to soften the return effect of the spring f. Two prisms may be actuated by the one rod j<1>, a coupling device consisting of two arms with pin and slot engagement being employed to ensure symmetrical and synchronous working.

Title: Improvements relating to track switch (point) indicators for railway traffic control system display panels
IPC: B61L25/08
Filed: 1958-03-17
Abstract: 871,694. Electromagnets. GENERAL RAILWAY SIGNAL CO. March 17, 1958 [March 21, 1957], No. 8551/58. Class 35. [Also in Groups XI, XXX and XXXVI] In a railway points position indicator on a control panel track diagram (see Group XXX), the electromagnetic structure consists of two selectivelyexcitable polepieces which co-operate respectively with peripheral armature portions so shaped as to define, in one limiting armature position, and in the other limiting armature position, a maximum airgap which decreases to a minimum on rotation of the armature towards its alternative limiting position on energization of the polepiece in said alternative limiting position. In Fig. 3, the armature 28, shown in its clockwise limiting position, is formed with two arcuate shaped peripheral portions 36, each of which terminates in an abrupt change of radial dimension adjacent its co-operating polepiece 20, so that on excitation of the right-hand polepiece 20, where the gap between the polepiece and armature portion 36 is a maximum, in order to bring the leading edge of this right-hand portion 36 from the maximum gap position located on one side of the line 33 joining the minimum airgap psiotion with the armature rotation axis, to a position beyond said line 33, the movement of the armature from one limiting position is initially relatively rapid but is reduced in speed as it approaches its other limiting position. The circular polepieces 20 are mounted eccentrically on cores 19, Fig. 4, mounted on respective legs 16 of a yoke 15, and each core carries an energizing coil 23. The polepiece 20 can be rotated, on slackening screws 22, by a tool inserted into one of the cross-drilled holes 39 in the piece 20. The armature 28 is secured on a hollow shaft 27, Fig. 3, mounted in two spaced nylon or " Teflon " (Registered Trade Mark) bushings provided in the side walls of an upturned angular bracket 25 secured on the front plate 17 between the polepieces 20 and cores 19. The armature 28 may be clamped by a set-screw 32 and has an upper arcuate surface 35, Fig. 3, for co-operation with an arcuate portion in a groove 37 cut in the yoke plate 15, a very small air-gap being formed therebetween and is such that during rotation of the armature, does not vary.

Title: Improvements in or relating to electronic storage and switching arrangements
Inventor: PERRY GERALD HORACE
IPC: H03K23/76
Filed: 1956-03-21
Abstract: 844,849. Circuits employing bi-stable magnetic elements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 13, 1957 [March 21, 1956], No. 8827/56. Class 40 (9). An arrangement comprising a magnetic storage core CA, Fig. 2, which provides a single output signal in response to two successive input signals and functions as a binary counter, has each input signal applied in the form of separate coincident current and voltage pulses to windings " 1 " and y respectively. The current input drives the core to the " one " remanent state, and if the core is initially in the " zero " remanent state a voltage is induced in winding y which disables a transistor gate TA in the voltage input circuit. A diode UA connected across coil y ensures that the voltage input is blocked by the gate for the duration of the input signal. The current input during the succeeding input signal is without effect as the core is already in state " one." No voltage is therefore induced in coil y, and the voltage input is effective over the transistor gate and a coil 2 X " 0 " to produce a current output, the latter coil having a sufficiently high m.m.f. to override coil " 1 " and drive the core back to the " zero " remanent state. The operative input signal also develops an output across a resistor RA, while voltage outputs are developed in a coil x without discrimination each time an input signal is applied. A number of the counters shown in Fig. 2 may be connected in cascade, in which case the cumulative effect of output pulse lengthening is minimized by the inclusion, at intervals, of the circuit shown in Fig. 3. In the latter arrangement a further core CB is used which is permanently biased in the " one " remanent state by a reset potential applied to a coil " I." The circuit output from CA is applied to CB by a 2X" 0 " overriding coil, and output voltage pulses of predetermined length are thereby obtained during the time periods when the core flux is changing. Specification 844,850 is referred to.
