Title: Improvements in pasting-mechanism, particularly for continuous-rod cigarette-making machines
IPC: A24C5/24
Filed: 1930-02-05
Abstract: 350,489. Pasting-mechanism for cigarette machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co. ; 511, Fifth Avenue, New York, U.S.A.) Feb. 5, 1930, No. 3923. [Class 130.] In a continuous-rod machine, the edge of the paper wrapper P, Fig. 7, is pasted by the lower flange of a grooved wheel 25 taking up paste from a recessed portion of a rotating drum 42, and the tobacco is impelled forward in the paper tube prior to pasting by a rotating disc 60, Fig. 1, operating through a longitudinal slot in the folding- tongue 63 of the rod-forming mechanism. The lower flange of the paste wheel 25 is of greater diameter than the upper, and is bevelled to form a vertical surface with the wheel inclined as shown in Fig. 7. The paste-supplying drum 42 is rotated. within a container 34 by means of a coupling 41 and worm gearing 35 driven from a shaft 13, and the wheel 25 is driven by spiral gearing from a shaft 20 geared at 27, 28 to the shaft 13. An adjustable slide 44 regulates the flow of paste in the recess of the drum 42. This drum is adjusted relatively to the wheel 25 by angular movement of the housing 31 carrying the drum, about the shaft 13. Vertical adjustment of the pasting- mechanism is effected by a hand-wheel 69, and the horizontal position of the wheel 25 may be adjusted by a screw 81. By means of a hand-wheel 73, the pasting-mechanism may be unlocked so that it can be swung aside from the cigarette rod. The periphery and sides of the drum 42 are wiped by blades rotating within the container 34, these blades serving also to agitate the paste. An electric heater may be fitted to the container. The impeller disc 60 is driven from the shaft 13 through worm gearing 53, 54 and gear wheels 61, 62, and is adjusted vertically by a set screw 65.

IPC: F16K31/53
Filed: 1923-02-10
Abstract: .202,588. Edwards, E. Feb. 10, 1923. Rotary disc valves.-A valve for preventing the unauthorized use of liquid, as for example petrol in a motor vehicle, consists of superposed rotary discs F each rotated by a gear wheel L meshing with the toothed periphery of the disc. The discs each have one aperture and must be adjusted separately until all the apertures are in register before fluid can be obtained. The discs are pressed into contact with each other by a plate J and a spring H, and are mounted within a cylinder integral with the valve casing, or inserted and held therein in any suitable manner.

Patent GB-1029511-A (GB)
Title: Improvements relating to porous sheet material
Inventor: CROFTS HARRY
IPC: C08J9/26
Filed: 1964-01-31
Abstract: Porous sheet material is made by melt-coating a free-flowing powder composition of a thermoplastic resin and a leachable powder with or without other constituents onto a porous carrier web, the leachable powder thereafter being leached out, and constituting 45-75% of the total composition by weight and being infusible at the melt-coating temperature.  The carrier web may be a woven, non-woven or laminated woven and non-woven, material and may be impregnated with a polyvinyl chloride composition.  The preferred thermoplastic resin is polyvinyl chloride or a copolymer of vinyl acetate.  The preferred amount of leachable powder is 50-65% by weight.  The powder particles should be between 50 and 240 B.S.S. mesh, preferably between 120 and 200 B.S.S. mesh. Another thermoplastic resin, for example, polyurethane elastomer, may be included to improve the abrasion resistance of the product. The leachable material may be sodium chloride, sodium carbonate, a surface active agent or dispersing agent such as sodium salt of an aromatic sulphonic acid, or hydrolysed starch.  A small amount of a blowing agent, such as sodium bicarbonate, may be added. Plasticizers, stabilizers, pigments and any other desired additives may also be incorporated.

Title: Improvements in decorated objects and methods of obtaining same
IPC: B44F1/04
Filed: 1937-02-15
Abstract: 486,906. Ornamenting. LATROBE, P. M. L. Feb. 15, 1937, No. 4411. Convention date, Aug. 17, 1936. [Class 93] [Also in Group XVI] Relates to the method described in Specification 416,350, [Group XVI], for producing iridescent effects on an article having a deformable reflecting surface by successive displaced embossings with a member having a grid-like surface the grooves of which are indistinguishable by the naked eye, and consists in reducing the reflecting power of that part of the reflecting surface which has not been embossed so as to produce a different ornamental effect. In one method, the whole of the surface is first treated to have its reflecting power reduced, the subsequent embossing restoring this power over the areas subjected to the latter operation. Alternatively, the non-embossed areas may be treated after the embossing operation, in which case stencil plates or impervious coatings must be used to protect the embossed areas during the treatment. The reflection-reducing treatment may consist in applying a matt coating of, for example, varnish, wax, an opaque paint, a non-transparent lacquer, or an ink, or may consist in deforming the surface by means of a sand-blast or by compression against a granular surface of greater hardness than the reflecting surface, e.g. emery paper, or by etching. An embossing-surface may be made from the article thus ornamented and used to ornament similarly other articles in one operation. Any part of the article may be coated with a transparent or translucent lacquer, enamel, or paint.

A rotary overhung centrifugal compressor assembly comprises a casing, a stationary section interposed between the inlet and outlet sides of the compressor, a locking ring in a groove in the casing, means on the stationary section abutting the locking ring and preventing movement of the stationary section in one direction longitudinally of the casing, clamping means fastened to the stationary section to engage and hold the locking ring against movement in the opposite direction longitudinally of the casing, and means on the clamping means interchanging with means on the casing for preventing rotational displacement of the section relative to the casing. In a two-stage centrifugal compressor having impellers 26, 28 and an inlet eye 31, an annular member 34 comprises elements 36, 38, 40 and 42 which form interstage and discharge guide passages. The member 34 is secured against axial movement in the casing 12 by a connection 60 and the elements 38 and 42 of the member 34 are similarly connected together by a connection 54. The connection 54, Fig. 5, has a snap-ring 82 located in an annular groove 84 in the element 38, and a clamping ring 88 is bolted to the element 42 by a number of circumferentially arranged bolts 94 to clamp the snap-ring between shoulders 86, 90 and also to retain the snap-ring radially. The ring 88 is secured against rotation by one or more pins 98 each projecting radially into a slot 102 extending laterally from the groove 84. An 0-ring seal 104 is provided. The connection 60 is similar to the connection 54, differing only in the shape of the clamping ring which protrudes from the surface of the element 36 as shown in Fig. 1. For dismantling purposes the end cover 16 may be removed by removing nuts 18 to provide access to the interior of the casing 12, and after removal of the eye 31 and the impeller 26, the clamping ring and snap-ring of the connection 60 may be removed for removal of the member 34 and the remainder of the rotor. The snap-ring is removed by a special tool which locates a hole in the side of the ring at each of its ends and compresses the ends together. A cut-out at the side of the groove containing the snap-ring, preferably at the bottom of the casing, allows easy access for the tool. A single-stage rotor may be substituted in a casing previously utilized in a two-stage machine.
