Title: Improvements in multi-layer sheets and articles made therefrom
IPC: C25D5/14
Filed: 1950-03-22
Abstract: 667,339. Electrodeposition on aluminium. MOND NICKEL CO., Ltd. March 22, 1950 [April 2, 1949], No. 7205/60. Class 41. [Also in Group XXII]  A composite sheet to be used for the deep drawing of cooking and like vessels is made by electrodepositing nickel on a sheet of aluminium or aluminium alloy to a thickness such that the tensile strength of the composite sheet is about twice that of the aluminium foundation sheet. The aluminium is prepared for coating by dipping in a 5 per cent caustic soda solution at 65 C. for 10 seconds, rinsing in water and dipping in concentrated nitric acid at room temperature for 10 seconds. It is then anodically treated for 10-15 minutes in 35-50 per cent phosphoric acid using a current density of 12 amperes per square foot and again rinsed in water. The nickel plating is started with a current density of about 10 amperes per square foot for 30 seconds after which it is increased to reach 60 amperes per square foot after one minute. If the aluminium was from 0.02- 0.04 inch thick, plating would be continued until each nickel layer was 0.003-0.004 inch thick. After rinsing and polishing a layer of chromium 0.0002 inch thick may be deposited.

Title: Improvements in magnetic snap action electric switches
Inventor: CHINN ARTHUR JOHN
IPC: H01H37/52
Filed: 1959-03-02
Abstract: 889,634. Thermal and partly magnetic switches. RHEOSTATIC CO. Ltd. Feb. 10, 1960 [March 2, 1959], No. 7229/59. Class 38 (5). A bimetal strip 15 is supported on a base 6 by means of a spring strip 16 and carries at its free end a twin armature 13, 14 co-operating with a permanent magnet 12 adjustably mounted on the base 6. An insulating member 18 depends from the free end of strip 15 and has a slot 19 for engagement with the end 20 of a switch blade 1 mounted on base 6 by a tongue 5. Blade 1 carries contacts 3, 4 for alternate engagement with contacts 9, 10 suitably carried on the base 6. Armature 13 is normally closer to magnet 12 than armature 14 and the strip 15 is thereby held down such that member 18 rests on the end 20 of the blade 1 and contact 3 is held against contact 9. A screw 11 serves to adjust this initial contact pressure. When heated strip 15 moves upwardly until armature 14 is closer to magnet 12 than armature 13, whereupon strip 15 snaps into its upper position and, after slight lostmotion due to slot 19, the blade 1 is snapped to bring contact 4 into engagement with contact 10. The switch differential is adjustable by a screw 17 which controls the total gap between the armatures 13 and 14. A knob 22, controlling pressure on a rigid tongue 33 riveted to strip 15, serves to set the operating temperature. The bimetal strip 15 may be replaced by a resilient strip and operation effected by a mechanical or thermal element, such as a rod and tube or bellows or diaphragm, acting on the tongue 33 in place of control 22. Alternatively the resilient strip 15 may be pivoted intermediate its ends and operated mechanically.

Title: Improvements in or relating to Phonographs and the like.
Inventor: PRETTIE RICHARD JAMES
IPC: G11B17/02
Filed: 1916-05-20
Abstract: 107,610. Prettie, R. J. May 20, 1916. Periodic; applied by springs. - In an automatic brake or stop for gramophones &c. of the kind in which a member moving with the tone-arm releases the latch of a spring-controlled brake when the end of the record is reached, the latch-releasing part or rod is adjustably connected to the latch so that, when disconnected, the latch-releasing rod adjusts itself relatively to the latch. Fig. 1 shows the mechanism in plan with part of the turntable removed, and Fig. 6 is a detail view of the brake latch and associated parts. The tone-arm is connected by an arm 10 and link 11 to a lever 12 pivoted on a bracket 14. The lever co-operates with the upturned end 29 of a spring-controlled rod 28, which slides in a bracket 30 attached to the baseplate 8. The other end of the rod 28 is flattened and passes through a vertical bolt 35 mounted in a pivoted arm or a latch 20, a spring 39 normally causing the rod to be gripped against the upper surface of the latch. When, at the completion of a record, the lever 12 engages the rod 28, the latch 20 is swung on its pivot 21 and the notched end 19 of the brake lever 17 is released, the brake block 15 being applied to the turntable rim by a spring 23. To reset the brake, the tone-arm is swung beyond the rim of the turntable until the lever 12 engages the end of a link 24 which disengages the brake and allows the notched arm 19 to be caught by the latch 20. In order to set the rod 28 for varying lengths of record, the rod is released from the latch 20 by pressing a button 38 on a lever 36, and the needle is placed opposite the last groove of the record, the arm 12 thus setting the rod 28 in the required position, in which it is clamped by releasing the lever 36. The other end of the lever 36 lies beneath the bolt 35, which is thus raised out of contact with the rod 28 when the button 38 is depressed. The brake can be applied or released manually by swinging the tone-arm to the extreme positions, and during the playing of a record the brake may be applied by pressing and releasing the button 38. This allows the spring 32 to move the rod 28 until its end 29 engages the lever 12, and the subsequent forward feed of this lever releases the latch 20 and applies the brake.

Title: Improvements in and relating to curable organopolysiloxanes
Filed: 1955-03-11
Abstract: A composition comprises a curable organopolysiloxane and, as curing catalyst therefor, stannous gluconate in amount, e.g. so as to provide 0.1 to 20 per cent of stannous tin ion by weight of the siloxane.  The siloxanes used may be liquid or resinous, in solution in organic solvents, e.g. toluene, xylene and butanol, or in aqueous solution or emulsion.  The siloxanes disclosed contain hydrocarbon radicals, which may be saturated or unsaturated aliphatic, aromatic or halogenated aromatic, may contain Si-H groups, may contain Si-Si bonds where silane mixtures, obtained by reacting methyl chloride with silicon, are used in making the siloxanes, or may contain terminal trimethylsilyl or methyldihydrogen silyl groups.  In examples are given (1) comparative curing rates of the cohydrolysate of methyltrichloro-, dimethyldichloro- and diphenyl dichloro-silane with stannous and stannic gluconates and metal carboxylates; (2,3,4) comparative durability tests on fabrics rendered water-repellent by application of siloxane emulsions per se or containing water - soluble urea - formaldehyde resins and containing different curing catalysts.  Other aminoplasts, e.g. trimethylol and hexamethylol melamines and dimethylol urea may also be incorporated in the emulsions, e.g. in amount of 3 to 35 per cent by weight of the emulsion.  Preferably the emulsions comprise (by weight) 0.1 to 50 per cent of the siloxane, 50 to 99.5 per cent water, and stannous gluconate in amount to provide 0.1 to 20 per cent of stannous tin ion by weight of the siloxane.  The compositions may also be used for coating and insulating conductors, for protecting surfaces in high temperature applications when heat-resistant fillers, e.g. finely-divided aluminium pigment, are incorporated.  Specifications 542,655, 548,911, 575,667, 597,834, [all in Group IV], 630,911, 632,954, 632,955, 745,154 are referred to.ALSO:Stannous gluconate of the probable formula: <FORM:0783302/IV (a)/1> may be made by reacting 1 mol. of stannous hydroxide with 1 to 3 mols. of gluconic acid or a derivative thereof, e.g. a metal salt thereof (Ba, Ca, Pb, Fe, Zn, Na or K) or glucono-delta-lactone; instead of the hydroxide, the chloride, sulphate or nitrate may be used.  Stannous gluconate is very hygroscopic.  The stannous gluconate used as a siloxane curing agent in the examples was made by adding the flocculent precipitate of stannous hydroxide, obtained by interacting 1 mol. of SnCl2 with 2 mols. of aqueous ammonia, to a 50 per cent aqueous solution of gluconic acid.

Title: Method of and apparatus for determining the density of a  cigarette rod or other rod of tobacco or filter material
IPC: A24C5/34
Filed: 1973-02-14
Abstract: 1422991 Testing cigarettes HAUNI-WERKE KORBER & CO KG 14 Feb 1973 [25 Feb 1972] 7298/73 Heading A2C [Also in Divisions G1 and G3] The density of a cigarette rod or other rod of tobacco or filter material is determined by two detectors 26, 27, one in which the rod is subjected to radio active radiation and the transmitted radiation is detected, and the other in which the rod is subjected to a stream of air which causes elastic deformation of the rod and the deformation is determined, e.g. by photo-electronic means. In a continuous rod cigarette manufacturing machine, Fig. 1 (not shown), the continuously produced rod 18 first passes through capacitor plates 57, 58 connected to a generator 59 which provides a signal dependent upon the moisture content of the tobacco. The rod then passes the first density detector 27 which comprises nozzles 36, 37 for directing air at the rod, a pulsed gallium-arsenide semiconductor diode 43, a silicon photo-electric element 44, lenses 49, 51 and diaphragms 47, 48. In place of one photoelectric device, a plurality of photo-electric devices may be provided in order to reduce the effect provided by small irregularities of the rod. Finally, the rod passes through the second detector 26 which comprises a #-ray source 31 and an ionisation detector 32. As shown in Fig. 3, the output of detector 26 is amplified and applied to a comparator 34 which also receives a nominal value signal from a source 35. The amplified output of detector 27 is corrected by the moisture signal in a device 53 whose output is applied to a comparator 54 which also receives a nominal value signal from a source 56. The outputs of the two comparators are applied to an amplifier 66 whose output controls the height of the rotary circular cutter 62 of the tobacco feed mechanism. The output of device 53 is also applied to a threshold value device 67 which is connected through a delay device 68 to the valve 69 of a pneumatic ejector. The rod is cut into cigarettes after passing through detector 26, and the ejector is operated to eject cigarettes which when tested by detector 27 produced signals which didn't reach the threshold value of device 67.

Title: Wiping mechanism for rotary plate printing machines
IPC: B41F9/14
Filed: 1923-03-15
Abstract: 215,506. Barker, R. W., (American Bank Note Co.). March 15, 1923. Inking - apparatus. - A wiping- mechanism for rotary plate-printing machines having a supply roll of wiping-cloth, a rewind roller for rewinding the cloth, and an intermediate platen over which the cloth passes so as to be intermittently engaged by and disengaged from the printing-plates, comprises feed-rollers situated between the supply roll and the platen and take-up mechanism situated between the platen and the rewind roller operated simultaneously and intermittently and while the wiping-cloth is disengaged from the printing-plate. The arrangement is such as to feed uniform lengths of fresh inking-cloth over the wiping-platen in the same direction as the movement of the printing-plate, uniform wiping conditions being ensured during the entire, run of the press. A clamp is arranged between the platen and feed-rollers and actuated so as to grip the cloth whilst the plate is being wiped and to release it whilst the cloth is being fed. The wiping-cloth passes from a supply roll 7, over a guide-roller 23, between feed-rollers 8, 9 and clamping-bars 29, 31, over wiping-platens 3, 4 and is rewound on a roller 28 by a take-up roller 24. The feed-roller 9 is actuated intermittently, at a time when no printing-plate on the platecylinder 1 is in engagement with the wiping- platens, by means of a ratchet wheel 11 and a pawl 13 carried by a spring-retracted arm 12 actuated by a link 2 and two-armed lever 19, 20 oscillated by rises 16, 17 of a cam 15 mounted on the shaft 14 of the plate. The take-up roller 24 is driven simultaneously with the feed-rollers 8, 9 but at a higher speed by a chain 26 and sprocket wheels 25, 27. During the feeding of the wiping-cloth, the clamping-bar 31, carried by pivoted levers 32, is lifted away from the bar 29 by a rise on a second cam 39 engaging a roller 38 on a bell crank lever 37 connected by a link 36 to bell crank levers 35 connected by rods 134 to the pivoted levers 32, but, by the time the feeding of the cloth is complete, the rise on the cam 39 passes the roller 38, enabling the springs 42 acting on the connecting-rods 134 to depress the bar 31 against the cloth so as to hold it securely whilst the printing-plate is wiping over the platens 3, 4. A projection on the face of the bar 31 enters a recess in the clamping-bar 29, thus taking up any slack in the wiping-cloth between the platen 3 and the clamp.

Abstract: 350,443. Synchronous movements. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats- Unis, Montrouge, Seine, France. March 7, 1930, No. 7548. Convention date, June 27, 1929. Addition to 345,964. [Classes 40 (iii) and 40 (v).] A brief intense signal (e.g. an interruption of radiation during 0À001 sec.) is sent after each exploration of a picture or after some fraction thereof, and gives rise at the receiver to a synchronizing current of longer duration, such as 0À06 sec. According to the parent Specification a local valve system controlling a synchronous motor is tripped into oscillation by the received synchronizing signals. In the system described in the present Specification the local " oscillator " is adjusted so as to be far from the oscillatory condition, but performs one oscillation for each impulse received. Thus the brief impulses may be applied through a transformer T to break down a discharge tube N. The resistance R and capacity C are so chosen that the resulting discharge and subsequent recharging of condenser C each last for 0À03 sec. By rhythmical repetition of this cycle an alternating voltage is applied to the coupling resistance r1, and an a.c. is applied through the valve L to the winding S of the motor which controls the scanning device at the receiver. The motor described in the parent Specification may be adjusted to run slightly fast and to be stepped back into phase by the arrangement now described.

Abstract: 725,711. Forging and cutting nails. WHEELING STEEL CORPORATION. March 19, 1953 [April 9, 1952], No. 7598/53. Class 83 (4). Apparatus for the manufacture of cut nails from continuous strip comprises means for intermittently advancing a continuous strip of metal, means receiving one end of said strip and cutting nail blanks therefrom in multiples of two lying in opposite directions, said blanks each having a small and a large end, means upsetting the large end of each blank upon completion of the cutting operation, and discharge means ejecting each nail from the apparatus after the upsetting operation. A continuous strip of steel is fed intermittently from a spool 19 to a position between a fixed lower die 18 and a vertically reciprocated upper die 17 and against a face 17c on the die 17 by rolls 20, 21, the roll 21 being driven by a ratchet 22 operated by a dog 23 on a ram 12 carrying the die 17 and reciprocated by a cam 16 on a main drive shaft 14. As the die 17 descends it co-operates with the fixed die 18 to punch two nail blanks from the end of the strip and then halts momentarily to allow spring-urged pushers 26, slidable by camoperated link means in a slot 27 in the base of each die, to push the nail blanks outwards so that their large ends protrude from the dies. The die 17 then continues to descend until the nail blanks are held firmly between the two dies, when it halts and pivoted cam-operated levers 33 swing in to strike the protruding large ends of the nail blanks to upset them to form heads. As the die 17 rises the pushers 26 eject the finished nails into bins 36.
