Title: Method of and apparatus for fitting tubes
IPC: A61F13/20
Filed: 1946-06-14
Abstract: 613,175. Telescoping tubes. McLAUGHLIN, J. R. June 14, 1946, No. 17874. [Class 99 (ii)] In an apparatus for assembling pairs of tubes in partially telescoped relation, particularly paper tubes 10, 11, Fig. 15, forming an applicator for a catamenial appliance of the type described in U.S.A. Specification 2,024,218, the ends of the larger tube are nicked to provide friction and a pair of tubes are advanced in tandem along a guideway, the leading tube being temporarily arrested while the following tube is moved independently to effect the telescoping. The tubes 10, 11 are respectively placed in bins 13, 14, removed through openings 17, 18 and placed singly in inclined shoots A, B formed by bent sheet metal members 23a ... 23d, Fig. 10. The discharge ends of the shoots deposit the tubes singly into a V- shaped channel 29 supported at the side of a table 32. A chain 44 passing over sprockets 41, 42, and driven by worm gearing from a shaft 52 has pins 49 extending therefrom, each of which engages behind a pair of tubes on the guide 29. This advances the tubes until the leading larger tube drops into a deeper portion 28a of the guide and thus brings the tubes into axial alignment. The leading tube is then engaged by a stop finger 54 carried on a pivoted lever 63. Spring hold-down fingers prevent dislodgment of the tubes during assembly. When the required telescoping has been effected a pin 49 engages a shoulder on the lever 63 and lifts the stop 54 clear of the leading tube after which continued travel of the pin moves the assembled tubes off the guide. The ends of the smaller tubes are slightly rounded at 69 to facilitate assembly. Before leaving the shoot A the larger tubes 10 are provided with indentations 10<1> to give frictional engagement with the inserted tubes. For this purpose, the shoot A is provided with a fixed blade 72, Fig. 16, and a spring-controlled blade 76, the latter being mounted on a lever 81 which is withdrawn by a pin 49 and then released to cause an impact which nicks both ends of a pair of adjacent tubes, Fig. 19. Reference has been directed by the Comptroller to Specification 603,282.

Abstract: 749,101. Air cleaners. AIR-MAZE CORPORATION. June 18, 1954 [Aug. 25, 1953], No. 17920/54. Class 8(2). An air filter of the oil-bath kind comprises upper and lower vertically aligned units each comprising a cylindrical housing 10 joined together at their contiguous ends e.g. by bolts 26 passing through ears 25 and each including a bowl 15 providing an oil reservoir 13 and an air inlet 11 at the rim, a skirt 17 depending from a cover 16 within the bowl down to the oil level 14, an annular filter element 18 spaced radially inwardly of the skirt 17 and including a baffle 19 extending upwardly from the bottom of the element, the filter including means whereby clean air is discharged from one unit centrally through the other but without traversing the filtering element thereof. As shown, the clean air from the lower unit is discharged through a central tube 22, a collar 31 and a tapered tube 20 of the upper unit where it is joined by clean air from the upper unit being discharged through an annular passage 21 formed by a collar 27 and the tapered end 20a of the tube 20. Each filtering element comprises a coarse mesh oil diffusion layer 18a, the oil baffle 19 and a plurality of fine mesh corrugated screens. In a modification clean air from the upper unit is discharged down a central inwardly tapered tube where it is joined by clean air from the lower unit being discharged through an annular passage formed by the end of the tapered tube and an upstanding collar. Specification 674,468 is referred to.

Title: Improvements in methods of producing photo-mechanical printing plates
IPC: G03F7/11
Filed: 1940-12-23
Abstract: 545,942. Producing photo-mechanical printing surfaces. CARTWRIGHT, H. M., HAIGH, A., and SMITH, F. H. Dec. 23, 1940, No. 18017. [Class 98 (ii)] A gelatine image is produced on a metal support coated with a substratum composed of a bichromated colloid such as bichromated gum arabic which has been hardened by light action, washed and dried, and coated with a silver halide gelatin emulsion by exposure, development in a tanning developer, removal of unhardened colloid by washing, and removal of the hardened colloid of the substratum by the use of an acidic solution of low water content. The support may be of zinc, aluminium, or copper. The exposure may be in a camera or in contact-printing. The gelatine image may be used as an etching resist and may be reinforced by carbonizing by heat, or reinforced with printer's ink or with a resinous or bituminous powder or with both, and the support etched to produce a relief or intaglio printing surface. The surface may be converted into a lithograph printing surface by coating with printer's ink with or without previous treatment with shellac or other varnish, and the gelatine image removed with dilute acid or sodium hypochlorite. The ink image remaining may also be used as an etching resist. The base may be coated with gum arabic sensitized with ammonium bichromate by flowing, whirling, and drying, is exposed to arc light or daylight, and is washed in cold water until the yellow colour is removed. After the substratum has dried, a photographic emulsion is coated thereon. The exposed emulsion may be developed with a tanning developer, containing pyrogallol or hydroquinone, the unhardened gelatine washed away with hot water, and the bare portions of the substratum removed with an aqueous solution of calcium chloride or glycerine, which may contain an acid or other solvent to etch slightly the underlying support, e.g. lactic acid, nitric acid, or ferric chloride. An aqueous or alcoholic solution of nitric acid or ferric or stannous chloride of sufficiently high density not to penetrate the gelatine may be used to etch the support further. The etching liquid may be removed with anhydrous ethyl alcohol. In a modification the emulsion may contain a hardening agent such as chrome alum and development may be effected with a non-tanning developer such as metol-hydroquinone followed by a stop bath. The image is treated with a solution dissolving the gelatine where silver is present, e.g. copper sulphate, potassium bromide, nitric acid, and hydrogen peroxide. The support is then treated as before. In another modification the image is first developed with a non-tanning developer, the emulsion is fogged by exposure to actinic light, and the residual silver halide developed with a tanning developer, followed by solution of the soluble gelatine, and treatment as before.
