Abstract: 780,937. Assembling can heads and bodies; seamed joints. BARNES CO., W. F. & J. Feb. 21, 1956, No. 5414/56. Class 83 (4). A can end seamer comprises a stationary frame, a circular bar fixed to said frame and arranged concentrically to a central axis and along a continuous arc, said bar having a seaming edge capable of initiating and completing the seam formation of a can cover and can body, rotary chuck means mounted to rotate about said central axis and also for movement towards and away from said seaming edge and means resiliently urging said chuck means towards said seaming edge and holding it in operative relation to said seaming edge throughout the entire seaming operation. A double seamer 10 comprises a frame 11 including posts 12 and a central drive shaft 13 carrying upper and lower spiders 17 and 14 respectively. The upper spider 17 is adjustable along the shaft 13 by rack and pinion gearing and carries adjustable seaming chucks 18 and the lower spider 14 carries can lifters 16. Rectangular can bodies 36 and corresponding can ends 37 are fed to the seamer at position A from a can body shoot 38 and a conventional can end feeder 39 respectively. The first seaming operation (Fig. 10) is effected by a seaming bar 42 and a second seaming bar 43 completes the double seam (Fig. 11) and at position B on the seamer the assembly is discharged on to a conveyer 45. At position A each can body is deposited on a lifter 16 comprising a pad 50 (Fig. 2) yieldably mounted on a shaft 51 slidably and rotatably mounted on the lower spider 14. A cam follower roller 55 on the shaft 51 rides on a circular cam 58 clamped to the frame 11. The cam 58 has a high-dwell 62, a low-dwell 63, a rise 64 and a recede (not shown). The rise is located at position A to elevate each lifter 16 to clamp the can end and body between the lifter and a chuck. The recede is located at position B. Each seaming chuck 18 is carried by a collar 75 on the upper spider 17 and comprises a tubular spindle 77 to the lower end of which is threaded a rectangular elliptical or hexagonal chuck 7. Each chuck is urged radially outwardly for holding the assembly against the seaming bars by springs 88 mounted on screws 87. A spring- loaded can ejector rod 99 engages a cam (not shown) at position B to knock the seamed can free from the chuck. The seaming chucks are rotated by a pinion 105 fitted on the spindle 77 and engaging with a ring gear 111 fixed to the machine frame. The stationary seaming bars 42 and 43 are adjustable to provide a warp or bias and each have an undulating contour including high points 122, low points 123 and transition points 124.

Title: An improved method of producing photographic dyestuff images
IPC: G03C5/40
Filed: 1933-06-23
Abstract: 426,260. Colour photography. GASPAR, B., 59, Rue de Jenbosch, Brussels. June 23, 1933, No. 5788 /35. Convention date, June 23, 1932. Divided out of 424,563. [Class 98 (ii)] Photographic dyestuff images are produced in photographic layers containing a silver image and a dyestuff forming substance or components by converting the metallic silver image into a chemical compound which locally nullifies the effect of a subsequently applied dyestuff forming bath. Reactions similar to those described in Specification 424,563 may be employed, e.g. the silver image is converted into a reducing compound, e.g. silver ferrocyanide, when employing an oxidizing agent to form the dyestuff; or into an oxidizing compound when employing a reducing agent. Thus, the silver may be converted into a reducing compound to prevent locally the oxidation of a leuco body on the diazotization or coupling of an amine. The dyestuff forming substances may be incorporated in the emulsion or subsequently and may be applied to a plurality of layers arranged on one or both sides of a support, or particles of different dyestuff forming substances may be juxtaposed in one or more layers. Specifications 298,979, [Class 98 (ii)], 395,718, 397,159, 416,566, and 416,660 also are referred to. The Specification as open to inspection under Sect. 91 includes the following examples : (1) a photographic layer has diffusely incorporated therein a leuco-ester &c., e.g. oftetrabromindigo or thioindigo pink, thioindoxyl, &c., either before or after development; after development, the silver is reduced with ferricyanide and the dyestuff is then formed at the non-silver portions by an oxidizing bath of sodium nitrite and hydrochloric acid; (2) an amine, e.g. p-nitraniline, p-aminophenylamine or dianisidine, is incorporated and, after converting the silver into a reducing compound, diazotization is effected by a nitrite solution and coupling effected with naphthol etc.; a self-coupling amine, e.g. m-phenylenediamine may be employed ; (3) salts of S or G acids are incorporated and are subsequently coupled with 2-diazo-5- dimethylamino-4<1>-methylphenylsulphone, the silver being converted into a reducing compound by sodium sulphide or a selenium toning bath ; a two-colour picture may be obtained by employing two layers suitably arranged on a support; (4) diacetylindigotine or di-isatogene, or other substance capable of reduction to a dyestuff, is incorporated, and the silver is converted into lead chromate or lead superoxide as described in Specification 379,679, the dyestuff being subsequently formed by a bath of pyrogallic acid or sodium hydrosulphite. Reference is also made to the formation of indamines, indophenols or quinonimine dyestuffs. This subject-matter does not appear in the Specification as accepted.

Title: Improved process for the manufacture of indiarubber articles
IPC: B29D99/00
Filed: 1932-02-26
Abstract: 386,464. Making goods from rubber dispersions. AUMARECHAL, J., 94, Rue du ChÔteau, Boulogne-sur-Seine, and ROBRIEUX, G., 24, Rue du ChÔteaudun, Paris, both in France. Feb. 26, 1932, No. 5796. [Class 70.] In the formation of articles from rubber dispersions, coagulation is accelerated by submitting the latex paste to the action of an intense electric current which increases the surface tension of the latex. The current may be supplied from a transformer or dynamo, or may be induced in the latex by high-frequency currents. The conductivity of the latex may be increased by the addition of such substances as sodium fluoride or zinc hyposulphite, or substances such as quinoline salts which decompose on the passage of a current to yield products which affect the surface tension, may be added. Colloidal metals may be added when induced currents are employed. The coagulation may also be facilitated by the addition to the latex of casein and a lactic ferment, or of sensitizers such as barium tungstate, sodium sulphate, lead tungstate or lead sulphate, which after being added to the latex, are irradiated with X-rays. For making sheets, a belt 1 on drums 2, 3, and being provided with current through brushes 6, 7 from a transformer 5, receives a layer 9 of latex paste from a hopper 8. The current may be passed directly through the latex by an alternative connection to the hopper. Radiators 14 and ventilator 15 assist the drying of the sheet. Dipped articles may be set by passing non- metallic moulds coated with latex paste (60-65 per cent rubber), into the interior of a coil through which is passed a high-frequency current of 15000-100,000 periods per sec. Suitable current density is 5000-10000 amps. per sq. dm.

The other grid 30 has its voltage varied so that it falls with increase .of voltage of the machine 2 thereby raising the potential of the grid 38 of the valve 35 and increasing the bucking field of the exciter. A potentiometer contact 52 provides a wide range of control of the regulated voltage. A potentiometer contact A provides adjustable compounding of the voltage regulation. If the grid 31 be connected to a point in resistance 45 the effect of variations in the voltage of source 25, 26 may be compensated. Specification 539,835 is referred to.
