Title: Means for marking cylindrical articles
Inventor: WEBSTER EDWARD
IPC: B41F17/22
Filed: 1959-12-15
Abstract: 910,380. Embossing. WEBSTER Ltd., EDWARD. May 14, 1961 [Dec. 15, 1959], No. 42543/59. Class 100 (2). [Also in Group XXII] A machine for embossing thinwalled cylindrical articles such as the shells of lipstick containers, comprises a rotatable disc 12 in which are mounted pegs 20, sleeves 21 which are rotatably mounted on the pegs and are of such an external diameter that the articles to be embossed are a close sliding fit on them, and a radially adjustable die 36 mounted at one side of the disc and having an arcuate inner face 35 bearing the design, the radius of curvature of the face 35 being equal to that of a circle touching the outer surfaces of articles on the sleeves so that it engages the articles as the are carried past it by rotation of the disc. The die 36 is carried by a block 38 which is mounted on the machine frame by a pair of bolts 39 passing through slots in the block. The block is accurately positioned in relation to the disc 12 by three pairs of locating screws 41, 42, 43 before being clamped to the machine frame by the bolts 39. A collar 24 is slidably mounted on each sleeve 21 and is carried by rods 25 which are slidable in holes in the disc. The rear ends of each pair of rods 25 are secured together by a plate and the assembly is spring-biased towards a position in which the collar 24 is close to the disc. As each peg 20 leaves the die a pneumaticallyoperated plunger strikes the plate at the rear ends of the corresponding rods 25 so that the collar 24 is urged away from the disc and ejects the embossed article from the peg. The plunger is actuated by means of a valve 30 which is opened intermittently by a pivoted lever 31. The lever 31 is rocked by a boss at the base of each peg 20 as the latter passes a lug on the lever. In use, the disc 12 is rotated continuously in a clockwise direction by an electric motor 15, the articles being placed on the sleeves 21 by hand. A guard 44 is provided to safeguard the operator's hands. Alternatively, the disc may be rotated in a step-bystep fashion in which case the articles are fed to the pegs mechanically.

IPC: D06P3/79
Filed: 1961-12-01
Abstract: Fibres of polyolefins, e.g. stereoregular polypropylene, and of polyacetals, e.g. polyformaldehyde, containing compounds of polyvalent metals are dyed with a metallisable dyestuff which is devoid of -SO3H groups and treated with an aqueous solution of a sequestering agent.  The specified polyvalent metals are Zn, Cu, Ni, Cr, Co, Mg, Al, Ca, Ti, Zr, Pr, Ce and La while the exemplified compounds are zinc, aluminium, nickel and magnesium stearate, chromium oleate, zinc nonanoate and calcium oxide.  The metallisable dyestuffs may be of the anthraquinone, azo, formazan, azamethine or heterocyclic series; they may be water-insoluble or may carry water-solubilizing substituents such as -COOH groups or salts thereof provided that the complex formed between the dye and the metal in the fibre is water-insoluble. Of the suitable azo dyes specified some contain hydroxy, alkoxy, carboxy, carbalkoxy or amino groups in ortho-position to the azo linkage or a heterocyclic N atom adjacent to the azo linkage to form the metallising system whereas in others the azo linkage forms no part of the metallising system, e.g. in azo dyes from 8-hydroxyquinoline, 4-hydroxybenzthiazole, 4-hydroxyacridine, 7-hydroxyindazole, salicylaldoxime, and the like. Numerous dyes from all the above series are specified.  The specified sequestering agents are sorbitol, pyrophosphates, triphosphates, oxalates, citrates, tartrates, gluconates, thioglycollates, aminotriacetic acid, hydroxyethylalkylenediaminetriacetic acid, diethylenetriaminepentaacetic acid and especially ethylenediaminetetraacetic acid and their water-soluble salts. The treatment with sequestering agent may be carried out at 50-150 DEG C. before, after or together with the dyeing.  Preferably the fibre is first scoured with a bath also containing sequestering agent and the dyed from a dyebath containing sequestering agent.  Examples are given.  Specifications 935,125, 966,487 and 966,489 are referred to.

Filed: 1966-09-27
Abstract: 1,161,055. Electric motors. ROCKWELL MFG. CO. 27 Sept., 1966 [28 Sept., 1965], No. 43062/66. Heading H2A. The permanent magnet field 30 of a D.C. motor for a hand-tool is protected from demagnetization by ripple in the supply and direct-on-line energization, by a boosting field coil 32 in shunt or, preferably, in series with the armature and wound round the magnets The invention is particularly applicable to motors fed from half-wave or full-wave rectifiers whose ripple would normally be injurious to the magnets. In reversible motors, Fig. 5, it may be desired to reinforce the flux in the trailing edge of the magnets only, and for this purpose the coils are divided into four, C-1, C-2 C-3, C-4, and the motor casing is apertured to allow one side of each coil to lie outside. The machine may be reversible, and the rectification may be combined with speed control by the use of SCR's. On normal load, the field coils provide about one-fifth of the field produced by the magnets. The magnets are of ferrite to avoid slot-ripple losses in the polefaces.

Abstract: 1,061,769. Gyroscopic apparatus; measuring angular velocity electrically. SPERRY RAND CORPORATION. Nov. 1, 1963 [Nov. 1, 1962], No.43188/63. Headings G1C and G1N. A rate gyro comprises a rotor 10 adapted to spin about an axis in a gimbal 12 which has rotational freedom about an axis normal to the spin axis constrained by a torsion bar 14, two semi-rounds 18, 20 of magnetic material being mounted on one face of the rotor 10 with a ring 28 of electrically conductive material provided to sandwich the semi-rounds 18, 20 between it and the rotor face, so that at points near the rotor face the reluctance vanes as the rotor rotates, two electromagnets 30, 32 symmetrically arranged so as to produce, when excited, magnetic fields passing through points of varying reluctance whereby the currents in the electromagnets are modulated as'a function of rotor speed, the magnetic fields also passing through the ring 28 so that a torque is exerted tending to rotate the rotor about the axis of rotation of the gimbal 12. The apparatus may thus be used to check rotor speed or the freedom of the gimbal 12. For rotor speed either one of the electromagnets 30, 32 is energized using switches 36 or 38 and the modulated current is fed to a frequency meter 40. For gimbal freedom, first electromagnet 30 is energized causing rotation of the gimbal 12 in one direction, this being sensed by a pickoff 42 coupled to an indicator 44, and secondly the electromagnet 32 is separately energized causing equal rotation of the gimbal in the opposite direction again sensed by the pickoff 42. The semi-rounds 18, 20 of magnetic material may be plated on the rotor 10 and the ring 28 of conductive material plated on top of the semirounds.

Title: Re-ignitable match
IPC: C06F5/00
Filed: 1962-12-05
Abstract: A re-ignitable match comprises a combustible core surrounded by a combustible body coated with a thin film.  The core is a match composition comprising an oxygen source, a fuel, a combustion rate retarder, and a binder, all dispersed in a dense non-porous polymer. The match composition is preferably one of those described in Specification 980,831. The body will usually not contain an oxygen source, and will employ a fuel such as metaldehyde in a polymer such as monomethyl methacrylate, styrene, polysulphide, acrylonitrile or methyl acrylate.  The core and body are simultaneously co-axially extruded and temporarily coated, e.g. with polyethylene, whilst curing is taking place.  After curing is completed and the temporary covering removed, the rod is coated with regenerated cellulose, cellulose acetate, P.V.C., or P.V.A.; this coating helps to prevent the body burning faster than the core.  The rod is finally cut into suitable lengths.

Abstract: 974,420. Door operating appliances. DARLINGTON CHEMICALS Ltd. Dec. 28, 1962 [Dec. 28, 1961], No. 46469/61. Heading E2M. [Also in Divisions G1 and H4] Electrical apparatus for the remote control of mechanical operations comprises radiation detecting means which on receipt of the required signal triggers a relay via a transistor amplifier, a reversible electric motor controlled by the relay to perform the desired operation and limit switches actuable selectively to reset the relay-motor circuit in readiness for the reverse operation on the next actuation of the relay. The preferred embodiment of the invention describes the opening and closing of garage doors when the presence of a car is detected in the driveway. Radiations which may be utilised include acoustic, magnetic fields and electro magnetic waves. Fig. 1 illustrates the use of magnetic fields. A transmitter 10 is mounted on the car and comprises a coil 18 and buzzer reed 16 connected across the battery supply 12 so acting as a buzzer. Alternating magnetic fields are set up in coil 12 and these are picked up by a detecting coil 24 positioned in the driveway. This signal is amplified by transistor 28 and triggers a thyratron 34 thus energizing relay 42. Relay 42 actuates a stepping or changeover switch 48 in the supply to the field coils of a motor 50 so as to reverse their connection each time the relay is actuated. On actuation of switch 48 motor 50 is energized-over the appropriate limit switch, (58 as shown), and is de-energized by opening of this limit switch at the completion of the operation. The other inoperative limit switch closes as the operation in question commences, ready for the next reverse operation. Alternative methods of signalling the presence of the car are described utilizing (a) a long wave e.m. radiation transmitter and a tuned circuit in the receiver and (b) a sonic or ultra sonic radiation transmitter and a microphone or other electro-acoustical device in the receiver.
