Title: Improvements in and relating to dynamoelectric machines
IPC: H02K1/18
Filed: 1949-06-20
Abstract: 660,942. Cores for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. June 20, 1949 [June 23, 1948], No. 16342/49. Class 35. In order to minimize the vibrations on the support of a dynamo-electric machine caused by the rotating field, stator laminations 14 are secured by longitudinal key-bars 15, the ends of which are in turn supported by longitudinal spring bars 16 through rings 26, the bars 16 are carried by web plates 20, 21, 22 and pass freely through web-plates 24, 25. The spring-bars 16 are arranged in two sets, one for each axial half of the machine, and the ends of each spring-bar are welded to the respective end-plate 19, to the web 20 or 22 and to the centre web 21 which connects the respective inner ends of the bars 16. The bars 16 are preferably made of two diameters as indicated by 16a, 16b to compensate for unequal axial distance spanned by the supporting rings 26. The web plates which serve to support the laminations and to divide the cooling air flow are either split as 20, 22 or cut back at their inner bores as 21, 24, 25, so that they do form a rigid mechanical connection from the casing 18 to the laminations 14. The required resilient mounting of the stator core is achieved by supporting entirely the latter from the centres of the spans of the spring-bars 16 by the webplates 20, 21, 22. Fig. 3 shows how the webplate 24 is holed to allow the spring-bar 16 to pass freely through it. Stop-collars 29 may be welded to the inner surface of the plate 24 so as to separate the bar 16 from the latter by a predetermined clearance. The similar webplate 25 is holed as the plate 24. Air seals 23, 28 of resilient packing material are respectively provided at the splits of the web-plates 20, 22 and at the junction of ring 27 and plate 24 (or 25). An air cooler may be provided below, at the side or on top of the machine.

Abstract: 685,231. Printing surfaces. HOE & CRABTREE, Ltd., R. June 30, 1950 [July 1, 1949], No. 16457/50. Class 100 (ii). [Also in Group XXII] To form a composite printing plate comprising a thin plate of magnesium alloy secured to a semicylindrical support or dummy of rigid material such as steel, one edge of the plate is bent around one straight edge of the dummy, the plate wrapped around the dummy from that edge, tension applied to the free edge which is then clamped to the dummy, tension then being released and the free edge bent around the other straight edge of the dummy to secure the plate thereto. A semicylindrical saddle 3, on a framework 1, has placed against it the dummy plate 4 to which is applied the magnesium alloy plate 5. One edge of the plate 5 is held against the corresponding edge of the dummy 4 by a screwed rod 11 while the edge is bent round the end of the dummy by a wedge shaped wipe bar 14 pivoted about an axis 15 concentric with the rounded edge of the dummy 4, the bar 14 engaging a groove 17 and being rotated by a lever handle 16 through approximately 180 degrees. A roller 24, pivoted at 23 to a framework 20 pivoted on an axis 21 concentric with the saddle 3, is then operated by a handle 27 on the frame 20 to wrap the plate 5 round the dummy, the free edge then being clamped and tensioned by a clamp 36. The clamp 36 is carried by a frame 38 having an angularly disposed member 41 with a slot 40 through which passes a screw 39 joining the clamp 36 to an operating handle 42, rotation of which retracts the clamp 36 to tension the plate 5. The plate 5 is then clamped by a screwed rod 43 and the clamp 36 removed. A wiping bar 32, similar to bar 14, then wipes the edge of the plate over the adjacent edge of the dummy to secure it thereto. The bar 32 is mounted so as to be swung up out of the way of the plate 5 as it is wrapped around the dummy by being pivoted at 33 to the frame 30 which is pivoted at 31 for the wiping operation. A hook 34 and pin 35 prevent clockwise movement of the bar 32 relative to the frame 30.
Patent GB-1601282-A (GB)
Title: Processing of paper fibre webs
IPC: D21H27/30
Filed: 1978-04-26
Abstract: For the treatment of paper webs, starch which does not gel in cold water is used. The starch gives the paper web better strength properties. In the case of multilayer paper webs, it serves as an adhesive for binding the individual layers. The process improves the starch action. This is achieved by the starch, before being applied to the paper web, being warmed to a temperature so close to the gelatinisation temperature that the starch particles, although swelling essentially completely, do not get gelatinised. In this warmed or subsequently re-cooled stage, the starch is then applied to the web. The heat energy during subsequent heat treatment of the paper web is then no longer partly lost to the swelling process, but serves exclusively for gelatinisation. This allows, for example, the interlaminar strength of multilayer paper to be more than tripled.

Title: Improvements relating to the nitration of tung or other vegetable oils
IPC: C11C3/00
Filed: 1919-07-04
Abstract: The nitration of fatty vegetable, animal, or fish oils, or the fatty acids derived from such oils, is effected in the presence of an inert solvent, and the product either used as such or after separation of the solvent.  According to the Provisional Specifications, the oil or fatty acid may be nitrated in the absence of a solvent.  The oils specially suitable are tung oil, castor oil, lumbang oil, ground-nut oil, cotton-seed oil, soya-bean oil, whale oil, linseed oil, or herring oil; whilst as solvents, white petroleum spirit and the naphthene residue from the nitration of Borneo spirit, are mentioned. The nitration is usually effected under agitation and using pure nitric acid with the application of heat, but dilute nitric acid may be employed and the reaction may take place under increased or reduced pressure or in the presence of an inert gas.  During nitration, ammonium nitrate, picric acid or nitrated benzol may be added; after nitration the excess of acid is neutralized by the addition of a nitratable solvent or of a base such as lime. Resin may be added before or after nitration, whilst pigments or filling materials may be added to the products, which may be employed in the manufacture of paints, varnishes, lacquers, cements, insulating compositions, and rubber substitutes.

Title: Improvements in and relating to offset lithographic printing machines
Inventor: KING CARL GUSTAVE
IPC: B41F13/36
Filed: 1951-07-16
Abstract: 728,737. Printing-machines. KAYE'S ROTAPRINT AGENCY, Ltd. June 24, 1952 [July 16, 1951], No. 16853/51. Class 100 (2). Offset machines, cylinder trips.- In an offset lithographic printing machine of the kind in which the offset cylinder is rotatably mounted on a shaft having eccentric end portions adapted to be rotated by lever means to displace the offset cylinder into and out of engagement with the forme and impression cylinders, there is provided an adjustable abutment to be engaged by a part carried by the lever means so that the final printing position of the offset cylinder relative to the forme and impression cylinders can be adjusted. The eccentric end portion 4 carries a bracket 5 to which are pivoted a pair of links 6, 7 connected by a third link 8. To link 7 is fixed an operating lever 9 having a handle 11 at one end and a roller 10 at the other. The roller is adapted to co-operate with abutment surfaces 13, 15 on a fixed bracket 12. The surface 13 is fixed while the surface 15 is adjustable being formed on a slide 14 which is spring loaded towards a helical cam 16 rotatable by a shaft 17 to move the slide. At its upper end the shaft 17 has an operating head 20 and an indicating arm co-operating with a dial 22. In operation, the lever 9 is first rotated into the position shown in Fig. 3 bringing the roller 10 into contact with the surface 13. The bracket 5 is held in this position, against the action of a spring 23 tending to turn it in an anticlockwise position, by a claw A pivoted to a fixed point A<SP>1</SP> and having an abutment a<SP>1</SP> engaging a stud 5a projecting from the bracket. When the machine is started the claw is automatically withdrawn to allow the stud 5a to move into engagement with the second abutment a<SP>2</SP> on the claw. This causes the roller to move along the surface 13 a short distance and the bracket 5 rotates in consequence to bring the offset cylinder 2 into contact with the forme cylinder 1. This is the inking position. After a further predetermined time the claw is withdrawn again so that the bracket rotates to the position shown in Fig. 4 and the roller 10 moves into abutment with the surface 15. In this position the link 7 abuts a face 5b of the cut-away in the bracket 5. The engagement between the roller 10 and the surface 15 therefore determines the extent of rotation of the bracket 5 and consequently the engaging pressure between the offset cylinder and the impression cylinder 3. This pressure is varied by rotation of shaft 17 and indicated on scale 22, adjustment being made for printing sheets of different thicknesses. If desired a gauge may be provided on the machine to indicate the thickness of the sheets being printed, the indicia of the gauge corresponding to those on the scale 22.

Abstract: 501,186. Typewriters. SMITH & CORONA TYPEWRITERS, Inc., L. C. June 10, 1938, No. 17281. Convention date, Jan. 29. [Class 100 (iv)] Paper feeding and guiding arrangements. -The paper-bail is positively arrested in an intermediate offposition by a stopdevice so arranged that the paper-bail, after a slight return movement, can be moved from the intermediate to the full off-position. A latch may be provided for holding the paper-bail in the intermediate off-position. The bail shown in Figs. 1 and 5 consists of a rod 14 carrying feed-rollers 17 and provided with arms 15, 16 which are pivoted at 19, 20 to the carriage 10. Thearm 15 is provided with a pin 23 for co-operation with a V-part 30 on a latch 22 pivoted on the carriage. The arm 16 carries, on a pivot 33, a stop-link 31 formed with a slot 32 which receives a pin 34 on the carriage and has rounded and sharp projections 35, 36 for co-operation with the pin. When the bail is pulled forward, the projection 35 and pin cause the link to swing, and the projection 36 co-operates with the pin to arrest the bail. On release of the bail it is moved slightly rearwards by the bail-spring 21, the link drops to release the projection 36, and the bail is retained in the intermediate off-position by the latch 22. The bail can be restored by rearward pressure thereon or by lifting the latch. If the bail is pulled further forward it is arrested in the full off-position by cooperation of the pin 34 with the end of the slot 32. On release of the bail, it is restored by the bail-spring, the projections 35, 36 riding over the pin 34, and the pin 23 riding over the V-part 30. Since the bail is not latched in the full off-position, it cannot be accidentally left in the path of the type-lever 13.
