Abstract: 534,056. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., SCOTT, R. H., GORSE, W. F., and HAYWARD, A. S. Dec. 21, 1939, No. 32673. [Class 100 (iii)] Magazines. - In multimagazine arrangements, in which the removal of a magazine is facilitated by spreading apart of the magazines above the one to be removed, the selection of the magazines to be spread is effected automatically by the adjustment of the magazine column. The spreading may be effected by the movement into operative position of one of the pivoted arms 5, on which the magazine is supported during removal, the selected magazine being at the same time separated from its base-frame, as described in Specification 525,412, or an independent lever &c. may be employed. Links 9. 10, pivoted to the base-frames of the top and lowermost magazines, are pivoted together, so as to form a toggle by which the top magazine is raised. The toggle is operated by a shaft 11, which is in connection with the magazine supporting-arm 5. The magazines below the top one are raised, in known manner, by lifting-hooks 14, 15 depending from the uppermost base-frame and adapted to engage with studs on the base-frames of the second and third magazines. According to the invention, the edges of the lifting-hooks are formed as cam-surfaces, which are engaged by fixed rollers 20, 20a, so as to move the hooks into and out of engagement with the studs on the magazines as the column is raised and lowered. The raising of a magazine before the matrices have been locked therein may be prevented by the engagement of a stud 44 on the arm 5 in a notch in an arm 46, which is held locked until the escapement locking-pawl is released.

Filed: 1948-12-22
Abstract: 668,844. Washing and drying machines. RAND WASHING MACHINE CORPORATION, H. J. Dec. 22, 1948 [Jan. 31, 1948], No. 33031/48. Class 138 (ii). A clothes washing and drying machine comprises a flexible air and water-tight bag 10 within which laundry is processed, and means to collapse the bag upon the laundry by creating a vacuum therein, the bag having a top opening for the laundry and an annular flexible sealing member 27 between the opening and a cover 11, which member is effective merely by placing the cover upon the opening. The bag 10 is contained in a tub 15 and contains a motor driven agitator 17 and, for the purpose of squeeze-drying the clothes, has a pump 20 connected to its base which extracts water and air from the bag to allow atmospheric pressure to collapse the bag. A pressure switch 16 is operated by the wall of the bag to limit the amount of water which enters the bag for washing purposes, this water being supplied through the base opening to which the pump is connected. The cover 11 besides providing an air and water-tight seal when the drying operation is in progress, allows escape of air during the water filling operations. In one construction, Fig. 2, the cover 11 is in two parts, a plate 11a which is connected by a hinge 28 to two pivoted levers 30 so that in its working position the cover remains substantially horizontal, movement of the levers being limited by rubber buffers 33, and a part spherical plate 11b connected to the plate 11a by a stud 25. Between the two plates is an S-section rubber sealing ring 27 sandwiched so that a lip 27a resiliently engages the turned-over top of the bag 10. This lip provides, with the top of the bag, an air-tight joint when a vacuum is produced in the bag but will allow air to escape from the bag. In a modification the sealing ring is of bellows form. In another construction the edge of the bag around the opening is provided with an outwardly directed lip which engages the part spherical part of the cover. The sealing ring is not then required on the cover. An annular shoulder on the cover is arranged to bear on a hard rubber ring surrounding the bag opening to limit downward movement of the cover to prevent jamming. An alternative construction, Fig. 4, has a sealing ring 41 on the underside of the cover which bears on the edge of the bag 10 and a valve 38 is provided in the cover, or, in a modification in the bag, to allow air to escape from the bag. Specifications 640,020 and 661,038 are referred to.

Abstract: 1,133,499. Coking pitch. ESSO RESEARCH & ENG. CO. 22 July, 1966, No. 33131/66. Heading C5E. Coke agglomerates 47 are formed by passing pitch particles (in liquid or solid form) down through a quiescent, non- turbulent fluidized bed 52 of coke, where the pitch first agglomerates the coke and is then cracked and coked. Coke particles, e.g. fluid coke from a reactor (10), Fig. 1 (not shown), is delivered at 42 at a temperature in the range 1100‹ to 1800‹ F. to a vessel 32, and a fluidizing gas (e.g. H 2 , H 2 O, CH 4 , N 2 ) is supplied at 48 to cool the agglomerates and remove fines, the gas velocity being regulated to ensure a non-turbulent bed 52. The pitch, which may be at 70‹ to 600‹ F., is supplied at 34 where the top of the bed is at a temperature in the range 800‹ to 1000‹ F., baffles 46 causing zig-zag passage of the agglomerates. The pitch may be derived from coal tar or from petroleum, and may be treated by oxidation or with chemical additives to promote carbon deposition, and fine carbon, e.g. fluid coke or carbon black, may be added to the pitch in amounts up to 50% b.w. A specific example, which includes particle sizes, gas velocity, and details of the pitch used, is described. Coke may be circulated via 44, 42 through a burner (see Fig. 1), and O 2 -containing gas may be burnt in the reactor 32 to maintain temperatures.

Abstract: 1391308 Finishing leather BARRETT & CO Inc 19 July 1972 [19 July 1971] 33789/72 Heading B5N A method of finishing leather comprises placing a leather substrate between a finish coating on a release layer and a backing layer having a finish-receptive surface in contact with the substrate, transferring the finish coating from the release layer on to the surfaces of the leather substrate and exposed areas of the backing layer opposed to the release layer, separating the release layer from the transferred finish coating, and removing the coated leather substrate from the backing layer. The finish coatings are preferably polyurethane, or acrylic resin in nitrocellulose emulsions, the acrylic resins being polymers of (meth)acrylic acid, alkyl (meth)acrylates, and/or (meth)acrylamides, and are preferably coated onto release papers having a polymethylsiloxane release coating. The leather and the backing sheet, which may be kraft paper, may be pre-coated with an adhesive acrylic coating from aqueous emulsion to promote adhesion of the finish coating. Preferably the backing layer is continuously unrolled and supports leather substrates. The coated relase paper is also continuous and unrolled over the substrate to form a compressed sandwich between a pair of transfer rollers, the roller nearest the release layer being heated. After stripping the relase paper, the supported and coated leather are passed between further rollers similar to those used for the transfer rolls to impart gloss to the coating. Alternatively, the coated release layer and backing layer are joined along one edge to form a finishing assembly and are of a size slightly greater than the substrate, each substrate being inserted into an assembly individually to form a sandwich which is inserted between the transfer rollers and further rollers. The finish layer may be two layers of different resins selected from those mentioned above and preformed on the release layer.
