Title: Improvements in or relating to lamps
IPC: B60Q3/04
Filed: 1942-06-20
Abstract: 554,183. Lamps for illuminating instrument dials &c. STEVENS. A. H.. (Electronic Laboratories, Inc.). June 20, 1942, No. 8499. [Classes 75 (iii) and 75 (iv)] [Also in Group XXXVII] Instrument dials are illuminated by a fluorescent lamp 6 having a bayonet-slot fitting in a socket 3 secured by a nut 4 to a cup 2 in an opaque cylindrical casing 1. A glass screen 12 only permitting the passage of near ultra-violet rays is mounted in the centre of a cap 10 secured to the front of the casing by screws 11. The cap is formed with a series of openings 13 surrounding the screen 12 and covered by a similarly slotted rotatable shutter 14 to allow the escape of visible rays if desired. Alternatively the screen 12 may be mounted in a cap which is hinged to the casing 1 so that it may be raised if visble rays are desired. A shaft 22 passing. through a cap 18 closing the rear of the casing and operable by a knob 25 carries a crank 34<SP>1</SP> which at the end of its movement in a clockwise direction engages an arm 30 in a casing 27 and moves it against the resistance of a spring 32 about its pivot 31 to cause a pin 29 to bridge contacts 28 to close the lamp-starting circuit which contains a resistance 26. The starting circuit is broken when the knob is released and the intensity of the lamp can then be regulated by rotating the knob in a counter-clockwise direction to cause an arm 21 to sweep over the coils of a rheostat winding 19 in series with the resistance 26. The lamp casing 1 is mounted on a stud 44 rotatable in a socket formed by arms 42 pivoted to a base 39, the arms 42 being clamped together by a bolt 45 and wing nut 46.

Title: Improvements in and relating to grinding and abrading mechanism
IPC: B24B49/04
Filed: 1936-03-23
Abstract: 465,683. Grinding and abrading machines. NORTON CO. March 23, 1936, No. 8595. Convention date, April 3, 1935. [Class 60] As a work-piece W is ground by a wheel G, a calipering member 18 is moved upwardly by a spring 16 and a lever 21 is operated by a spring 51 to depress a rubber diaphragm 29 covering a box 27 containing mercury or other liquid. The mercury is thereby forced upwards in a tube 34 having an internally tapered upper portion 36 formed of insulating material. When the work-piece has reached a predetermined size the mercury completes a circuit from an electrode 35 to an electrode 41 and stops the feed-mechanism of the wheel G. Grinding continues by reason of the strain set up in the machine parts and when the work has reached the required size another circuit is completed from the electrode 35 to an electrode 43 and energizes a solenoid as described in Specification 363,695 to cause the wheel G to move away from the work. The electrodes 41, 43 are threaded in metal insets 39, 40 in the upper portion of the tube 34, the electrode 41 being adjusted by rotation of a knurled head 47 acting through gearing 45, 42 and the electrode being adjusted by rotation of a knurled head 44. The mechanism may be mounted in a hollow base 5 mounted on the grinding machine table 1.

Abstract: 632,223. Moulding filled capsules. SALFISBERG, L. L. March 31, 1947, No. 8692. [Class 87 (ii)] [Also in Groups II and XVII] Strips of packaging material 1 and 2, e.g. thermoplastic material such as material having the registered trade mark " Cellophane " or " Pliofilm " or material, e.g. paper, having a thermoplastic coating, are drawn from supply rolls by rollers 5 and 6 which have corresponding recesses 17 providing a clearance space for the tablets A between the strips 1 and 2. Surfaces 18 of the rollers 5, having e.g. circumferential and transverse grooves, crimp or seal and press together the strips 1 and 2, as at 19, between two adjacent tablets. The longitudinal edges of the strips 1 and 2 are pressed together and crimped or sealed by the roughened parts of the rollers 5, which may be heated for heat-sealing. After each transverse sealed zone is formed, a tablet is pushed from the chute 7 between said strips. Preferably the plunger 9 follows the tablet to hold it in position until the strips close around the tablet and is then withdrawn. As the longitudinal edges of the strips 1 and 2 are being sealed, the studs 24 crush the tablet within the two corresponding recesses 17. The strip passes on to a severing mechanism. Specifications 441,315 and 632,230, [both in Group XVII], and U.S.A. Specification 2,180,966 are referred to.

Title: Improvements in or relating to the treatment of gaseous products of the decomposition of volatile metallic chlorides
IPC: C01B7/00
Filed: 1949-04-01
Abstract: Chlorine is obtained from gases from the decomposition of volatile metallic chlorides by free oxygen-containing gases by treating the gases with a liquid anhydrous absorbent selective to chlorine and subsequently expelling the chlorine, e.g. by heat. Absorbents may be sulphur monochloride, carbon tetrachloride, metallic chlorides such as titanic chloride or tin tetrachloride, or chlorohydrocarbons such as pentachlorethane, trichlorethylene or hexachlorbutadiene.  Thus titanium chloride vapour is decomposed by an oxygen, carbon monoxide and dioxide gas mixture, and the resulting mixture of chlorine, carbon dioxide, and oxygen, after separation of titanium oxide, is passed to an absorption column counter-current to titanium tetrachloride with cooling to O DEG C.  Chlorine is expelled in a still and rectification column by heating at 230 DEG C. at 8 atmos. and is passed through a dephlegmator, kept at 40 DEG C. to condense remaining absorbent, to a cooler and liquefier.  The residual gases from the absorption column may be passed to a second absorption column wherein water under pressure removes carbon dioxide and residual chlorine, or some 70 per cent of these gases may be recycled with make-up oxygen to the treatment of chloride.  The tetrachloride absorbent is returned from the still through a cooler to the first absorption column.  Specification 12743/08, [Class 90], 641,801, and 661,685 are referred to.

Title: Improvements in prepayment meters for electricity, gas and the like commodities

Abstract: 454,252. Prepayment mechanism for meters. WALL, G., Rhosneir, Stretford Road, Urmston, Manchester, and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd., 1, Kingsway, London. March 26, 1935, No. 9454. [Class 27] In prepayment meter mechanism in which a variable-gear device for obtaining a progressive change of gear ratio is provided between the meter rotor, or the equivalent, and the commodity side of the prepayment differential, an auxiliary motor drives the commodity side of the differential through a variable gear device under the control of the meter rotor. An auxiliary motor, comprising a spring 38 wound by prepayment from the coin receiver mechanism 31 through gearing 40 .. 42, drives a shaft 2 under the control of an escapement 35, 36, the member 36 being driven through gearing 5 from the index spindle 6 which is driven by the meter rotor, and the member 35 having a pin 43 which engages notches 44 in the disc 36. The shaft 2 carries an arm 1 provided with a pawl 7 which during each revolution of the shaft meets a fixed stop 10 to engage it with a ratchet wheel 11 loose on the shaft, the pawl being disengaged by an adjustable stop 15, which is positioned by means of a locating disc 16. The pawl and ratchet constitutes a variable drive which is transmitted through a wheel 13 integral with the ratchet wheel and wheels 20, 21, 22, 23 to the commodity side 24 of a prepayment differential P, the other side 26 of which is set forward by the coin mechanism. As shown, the meter rotor may also be geared from the shaft 6 to one sun-wheel 45 of an auxiliary differential A, the other sun-wheel 46 of which is geared to the wheel 13. The planetary cage 47 of differential A is geared to the commodity side 24 of the differential P. In this case, the movement transmitted to the wheel 24 is the resultant of the movements imparted to the sun-wheel 45, 46 by the meter rotor and by the auxiliary motor, this resultant being the sum or difference of the movements of wheels 45, 46. The mechansm in this case is used to vary the price of the commodity above or below a normal price represented by the movement of the sun-wheel 45. A helical spring 54 may be provided to relieve the meter rotor of the work of driving the mechanism. The spring 38 may be wound by an auxiliary electric motor instead of by the coin-mechanism. Specification 253,997, [Class 27], is referred to.
