Abstract: 216,312. Parsons, G., and Middlebrook, J. A. May 4, 1923. Colorimeters.- Colour display apparatus consists of a rotating disc E, having a number of coloured sectors mounted to rotate in unison with a plate or mask E having an opening through which one of the sectors may be viewed. Means are provided whereby the relative position of the disc and plate may be adjusted during rotation. The disc E and plate F are mounted on co-axial shafts C, D respectively, the shaft C being rotated at a high speed. On the shaft D is keyed a sliding collar G connected by rods H to a similar collar K on the shaft C. Pivoted to an extension of the collar G is, a pawl L engaging a ratchet M driving through a worm the wheel P fixed on the shaft C. Movement of the collar G by the handle Q causes the relative positions of the shaft C, D to be altered and thus to expose in the opening of the plate F portions of two adjacent sectors of the disc E. The plate F is coloured a dead black and the result, when the shafts are rotating, is to display a complete disc of substantially the colour resulting from a mixture of the colours in the proportions exposed in the aperture in the plate F.

Abstract: 1,191,014. Luminescent materials. THORN LIGHTING Ltd. 10 May, 1967, No. 21676/67. Heading C4S. A phosphor consists of a compound of trivalent cerium oxide and aluminium oxide having the #-alumina crystal structure; divalent manganese oxide may also be included. Preferred phosphors may be expressed as xCe 2 O 3 .yAl 2 O 3 , where x: y is is 1: 8 to 1: 13, preferably 1: 10.5 to 1: 12.5 and xCe 2 O 3 .zMnO.- yAl 2 O 3 , where (x+<SP>1</SP>/ 3 z): y is from 1: 8 to 1: 13, preferably 1: 10.5 to 1: 12.5 and x: z is 1: 0.125 to 1: 1À25, preferably 1.025 to 1:1. The preferred cerium aluminium oxide phosphors have a blue emission from 3000 A to 6000 A peaking at 4600  under 2537 A while the inclusion of divalent manganese oxide suppresses the 4600 A peak producing a peak at 5200 A, increasing content causing a shift to 4800 to 6000 A emission peaking at 5200 . Excitation by 3650 A and cathode-rays is mentioned. In the preparation, the constituent oxides or materials which yield oxides onfiring, Al 2 O 3  and cerous oxalate, for instance are mixed and heated together in a reducing or inert atmosphere, e.g. hydrogen, at 1200 to 1700 C., e.g. 1580 to 1680 C. to produce the cerous manganese aluminium oxide phosphor. Divalent manganese oxide or manganese carbonate for instance may be added and refired in a reducing or inert atmosphere at 1200 to 1400 C. Use in fluorescent lamps is instanced. The phosphor should be cooled in reducing or. inert conditions to maintain the trivalent state (e.g. in hydrogen or hydrogen/ nitrogen).

Abstract: 680,060. Injection-moulding sliding-clasp fasteners. PLASCO, Ltd. Sept. 6, 1950 [March 20, 1950], No. 21935/50. Class 87 (ii). [Also in Group XXII] In a machine for casting groups of the elements of a sliding clasp fastener on to a tape which is intermittently fed through the machine control means are provided so that, the feed of the tape at a point between separate fastener lengths may be reduced if desired, as when some elements have been omitted from the last casting of the length. The tape is fed by grippers 14 which are opened and closed by compressed air supplied to a pipe 17 under the control of timing mechanism. Positive downward feed movement of the grippers is effected by a rod 23 and a return idle movement is effected by a spring 20. The lower end of the rod 23 is adjustably connected with one end of a bell-crank 27 which is connected at 28 with a lever 29 fixed to a rod 30 to which is also keyed a lever 31 bearing against a cam 33. The other end of the bell-crank carries a roller 36 projecting into a segmental grooved cam 37 normally held by a spring 45 against a stop screw 50 so that the segment is concentric with the rod 30. A pin 39 mounted in the machine frame carries the segment 37 at one end and at the other end a lever 41 carrying a rounded extension adapted to be engaged by a plunger 47. If it is desired to reduce the feed of the tape, the plunger 47 is actuated to move the lever 41 into engagement with an adjustable stop 51, thus turning the segment 47 so that it is no longer concentric with the rod 30. Actuation of the lever 31 by the cam 33 then effects a smaller movement of the rod 23 and grippers 14. Specifications 605,203 and 611,702 are referred to.

Title: Apparatus for splicing cinematograph films
Inventor: CATOZZO LEO
IPC: G03D15/04
Filed: 1958-10-13
Abstract: 876,393. Cinematograph film splicers. COSTRUGIONE INCOLLATRICI RAPIDE S. A. R. L. Oct. 13, 1958, No. 22024/60. Divided out of 855,321. Class 98(2). A device for splicing cinematograph film comprises a base having a die plate 53 in which is a row of perforations 58 corresponding to the film perforations, and also locating pins 55 which can engage in these perforations; a roll of adhesive tape 62 is so mounted that the tape can be unrolled across the join between the pieces of film to be spliced; an arm 73 is mounted so that it can pivot about an axis 70 at right-angles to the length of the die plate, and carries punches in register with the perforations; also mounted on this arm are a pair of cutter blades 79, so disposed, with their cutting edges parallel to the length of the die plate, that they sever the tape flush with the two edges of the die plate. Before splicing, the edge of each piece of film may be trimmed by placing it on a further plate 65 having locating pins 67, and cutting it across with a guillotine blade 68 acting against the edge 66 of the plate 65. The two pieces of film to be spliced are then positioned on the die pla'e by means of the pins 55 so that their ends either abut or overlap. Adhesive tape is unrolled so as to cover the whole width of the die plate 53, and then the arm 73 brought down so that the tape is severed. At the same time holes are punched in the tape where it covers the film perforations. The arm has a lower plate 75 which is used to keep the film pressed down while allowing the arm to be raised sufficiently for the punches to be disengaged from the film. The severed portion of the tape is wider than the film 57, and can therefore be folded underneath to reinforce the join. This modification of the splicer described in Specification 855,321 is particularly suitable for sub-standard film having perforations along one edge only.

Abstract: 1282352 Radio navigation TOKYO KEIKI KK 7 May 1970 [14 May 1969] 22087/70 Heading H4D [Also in Division G4] In apparatus for measuring the time interval between two signals, e.g. Loran A and B pulses, Fig. 2A, each of repetition period T, a counter 7 is coupled to a clock pulse source 5 via a gate 6, a clock pulse source 10 is coupled to a reversible counter 9 and a detector 8 generates a pulse PQ when the counters agree, pulse PQ controlling a gate generator 4 and being utilized to determine whether counter 9 stops counting or counts upwardly or counts downwardly. A known Loran synchronizer 3 produces inter alia the B pulses, Fig. 2E, and S pulses, Fig. 2D; the time interval measured is #T, the time interval between A and B pulses being (T/2+#T). Gate generator 4 produces a pulse G between the end of pulse S and the beginning of a pulse PQ (see below); the apparatus operates to make the duration Td of pulse G equal to #T. Pulse G gates counting pulses CP1<SP>1</SP> from clock pulse generator 5 and the output of counter 7 is compared in detector 8 with that of reversible counter 9 to produce pulse PQ. The counting in counter 9 of clock pulses CP2 from a source 10 is controlled from a unit 11 as follows. Manual operation.-Switch 18 is placed in position m. A pedestal pulse PB, derived from pulse PQ, is indicated on cathode-ray tube display 2 and if for example the B Loran pulse indicated thereon follows pulse PB an "addition command" is produced and applied to reversible counter 9; when pulse PQ gradually moves to the right until, when the pulse PB is seen on the display to coincide with the B pulse, a "stop command" is made; a Nixie (Registered Trade Mark) display 12 then shows the time interval #T. Automatic operation.-Switch 18 is placed in position o, after the manual lining-up of pulses PB and PQ on the cathode-ray tube display has been effected. Generator 16 derives the appropriate command of counter 9 under the control of a circuit 15 which compares the phase (timing) of pulses PB and B.
