Title: Improvements in or relating to doctor devices for photogravure printing machines
IPC: B41F9/10
Filed: 1954-06-17
Abstract: 751,549. Printing-machines. MASCHINENFABRIK AUGSBURG - NURNBERG AKT.- GES. June 17, 1954 [June 17, 1953], No. 17861/54. Class 100 (2). Inking-apparatus.-In a rotary intaglio printing machine wherein the doctor shaft 3 is substantially below the axis of the forme cylinder 13, Fig. 4, and a rocking lever 11 fixed to the shaft 3 for moving the doctor quickly to or from the forme cylinder has its movement limited by stops, at least that stop 10, Fig. 1, or 17, Fig. 4, which is operative when the doctor is applied to the forme cylinder is secured to, a second lever 9 connected via a slide block 8 to the wormwheel 5 of a fine adjustment means 6, the second lever 9 being mounted freely on the doctor shaft and being so engaged with the slide block 8 as to slide thereon when the doctor and its shaft are reciprocated but to be rotated therewith under control of the fine adjustment means 6. As shown, the lever 9 is forked at its lower end to embrace the block 8. In Fig. 1 the lever 11 is manually operated and the stop 10 comprises a capstan-head screw which contacts the ends of a slot 12 in the lever 11 in the limit positions of the latter, and by which the levers 9, 11 are clamped together. In Fig. 4 the lever 11 is hydraulically or pneumatically operated by a motor 16 mounted on the lever 9; on admission of pressure fluid thereto under control of a manual valve (e.g. a single valve in a multicolour photogravure machine) the piston 15 through a plunger 14 forces the lever 11 against the stop 17, and in this state the fine adjustment is made by the worm means 6; when the pressure is relieved a spring 18 retracts the doctor until the piston 15 abuts the motor cover. Electromagnetic means may replace the motor 16.

Title: Method of making knife blades and the like
IPC: B21H7/10
Filed: 1924-07-30
Abstract: 231,378. Marks, E. C. R., (Wade & Butcher Corporation). July 30, 1924. Cutlery and like blades.- Articles having relatively thick and thin edges, such as table knife blades are made by shaping a blank to a form in which it has approximately the width of the finished article, has relatively thick and thin edges and has excess metal adjacent the thick edge. The blank is then rolled longitudinally to lengthen it and to crowd the excess metal along the thick edge to lengthen the latter in compensation for the natural differential elongation of the thick and thin edges. A cylindrical blank is heated and forged by a hammer and dies or by a rolling- mill, to produce the blank 10 in which excess metal 14 is located near the thick edge. Transverse ribs 16 may also be formed on the blank. The work is reduced to final dimensions in a subsequent longitudinal rolling operation.

Title: Improvements in Variable Speed Gear.
IPC: F16H3/72
Filed: 1918-11-06
Abstract: 124,159. Crossley Motors, Ltd., Wishart, T. D., and Harrop, T. N. Nov. 6, 1918. Variable-speed and reversing epicyclic gearing, applicable to motor-vehicles, may be arranged to employ the power of the engine to brake a vehicle. In the form shown in Fig. 1, a sun-wheel B on a motor-shaft A gears with planet wheels C carried by a disk D, and the planet wheels engage an annular wheel J fixed on a casing H, K' on the driven shaft K. The disk D is keyed to a sleeve DS loose on the shaft A and provided with a brake drum 0, and also carries a number of rollers E adapted to work against plungers F in different phases in the end of the casing H. The plungers F are in communication through passages f, f and a central chamber g filled with liquid, and in the chamber g is a valve G connected with a lever W, by which communication between the plungers can be varied or entirely cut off. When the valve G is fully open, the plungers F are free and the disk D and planet pinions are unrestrained, and no drive is transmitted to the shaft K, and when the valve is fully closed, the plungers are immovable and the shaft K is driven at the same speed as the engine shaft A; intermediate speeds are obtained by varying the opening of the valve. Reverse speeds are obtained by applying the brake P to the drum O and thus controlling the disk D. Adjustable plungers M may be provided to cause the liquid to fill the passages f, f and chamber g. A car may be braked by applying the brake P to check the planet-carrier D.

Title: Improvements in or relating to two-roll mills
Inventor: MILLS DEREK JOHN
IPC: B29B7/58
Filed: 1958-06-06
Abstract: 854,662. Roller mills for compounding plastic materials. B.X. PLASTICS Ltd. Sept. 3, 1959 [June 6, 1958], No. 18217/58. Class 87(2). Thermoplastic material, e.g. polyvinyl chloride or rubber is fed into the nip between rollers 1, 2 and banded round the roller 1 with which is associated two blades 8, 9, the blade 8 being movable towards the roller 1, by the operation of air cylinders 12, 13, to cut back the greater part of the length of material banded around the roller and extending from one end of the roller and the blade 9 being movable, by the operation of an air cylinder 17, to cut back a narrow strip of material banded around the roller 1 near its other end. The air cylinders 12, 13, 17 are mounted on a composite beam 7, spanning supports 4, 5, so that the blades 8, 9 are parallel to the axis of the roller 1 in a plane about 25 degrees to the vertical, and are slidable on fixed supports. A trimming cutter 20 is pivoted to the blade 8, near its inner end, and biased towards the roller 1 by a spring 24, adjustable by a wing nut 26. Two trimming cutters 21, 22 are pivoted at their ends on a rod 27 and through them is screw-threaded a rod 30 which also passes through links 31. The links 31 are also pivoted on the rod 27 which is mounted in lugs 28, 29 at the ends of the blade 9. The links 31, and therefore the cutters 21, 22 are adjustably biased by springs 35. The rod 30 is screwed with opposite handed threads and so provides means for adjusting the distance between the cutters 21, 22. When the plastic material has been banded around the roller 1, both blades being withdrawn, air is admitted to the cylinders 12, 13 to advance the blade 8 to cut back some of the material which falls into a tray 6, leaving a layer still on the roller. The blade 8 is moved back again and the cut-back material, still connected with the remainder of the band on the roller, is pulled back manually and folded on to itself, and the operation is repeated until thorough mixing has been performed. To remove mixed material air is admitted to the cylinder 17 to advance the blade 9 which cuts back the narrow strip, and a similar process is followed as for the blade 8, except that, after this, the blade 9 is brought momentarily down again to sever the cut-back strip from the material on the roller. The most effective width of the strip, adjustable by the spacing of the blades 21, 22 is found by experiment. In a modification, Fig. 6, the trimming cutters 20, 21, 22 are mounted in holders 38, 39, 40 on the ends of piston rods from air cylinders 44, 45, 46 which are controlled from air valves 49, 51. A roller 54 bridges the gap between the holders 39, 40 and is resiliently pressed against the roller 1 by a spring 55 to prevent untouched material from being pulled off the roller 2. The roller 54 may serve as an endless support of a delivery conveyer belt. Instead of the air cylinder control valve being manually operated control may be automatic according to the needs of the mill.

A counter carried by a vehicle for road or parking toll-charging systems, responds in succession to one or other of a pair of frequencies to allow stepped advance by a spring motor 25 or 25a of an input 37 or 37a to a differential mechanism 40, the inputs being of different magnitude. Each half step of 37, 37a rotates a disc 32 or a flag 32a through 90 degrees to indicate whether the vehicle is in a toll and/or a parking zone. The differential mechanism drives a counter 36 to show the total charge. Detailed modifications are described.

Abstract: A starch derivative has an apparent M.W. of 35,000-350,000 and a ferricyanide reducing number of 14-20 (both terms are defined in the Specification), and may be prepared by treating a starch, preferably which contains at least 5% amylose, in the spark-discharge apparatus described and claimed in Specification 1,122,181. The product is useful for sizing paper (see Division D2).  The apparent M.W. is calculated using I.V. measurements; the ferricyanide reducing number indicates the proportion of reducing groups present, which is higher than normal in the novel derivatives of the invention. Corn and waxy maize starches are exemplified.ALSO:A starch derivative having an apparent M.W. of 35,000-350,000 and a ferricyanide reducing number of 14-20 (both terms are defined in the Specification) is used as a sizing agent in producing paper.
