Abstract: 384,293. Coating webs. DU PONT DE NEMOURS & CO., E. I., Wilmington, Delaware, U.S.A. Feb. 25, 1931, No. 5944. Convention date, Feb. 25, 1930. Void [Published under Sect. 91 of the Acts]. [Class 140.] A method of applying stripes of colouring material to sheets or webs of paper or fabric comprises feeding a thin ribbon of liquid coating material on to a travelling band of paper &c. The ribbon of coating material is fed from an aperture in a member in contact with the travelling web, the aperture being on the forward side of the line of contact, and the inclination of the member to the web being variable to control the amount of material applied. Apparatus for carrying out the method comprises a metal trough consisting of walls 1, 2, Fig. 2, having one or more holes 3 formed at the lower angle. The general arrangement is shown in Fig. 1. The web is drawn from the roll 13, passes over a roll 14 and under the trough 2. The trough is secured to a bar 6 to which is secured at each end a bracket 7. The brackets 7 are pivotally connected to brackets 8 which are fixed to the framework of the machine, a limited angular adjustment of the trough being permitted by the pivots and by means of bolts passing through holes in one bracket and through arcuate slots in the other bracket. The colouring matter is confined in the trough by means of rubber bulkheads 5. After passing under the trough the web passes through a heated drying chamber 17 and is then received on a roll 15. Different colours may be applied by different apertures by suitably dividing up the trough by means of a number of bulkheads 5, or, in a modification, the trough may be divided by a longitudinal partition 20, Fig. 5, some of the apertures 24 leading to one side of the partition, while other apertures 23 lead to the other side, different colours being disposed on each side of the partition.

Title: Improvements in or relating to change-speed transmission control system
IPC: F16H61/00
Filed: 1956-02-28
Abstract: 801,787. Change-speed control. STUDEBAKER-PACKARD CORPORATION. Feb. 28, 1956 [Aug. 3, 1955], No. 6146/56. Class 80 (2). A relay switch 106, closure of which opens a solenoid valve 88 to supply pressure fluid 76 to a piston 60 for upshifting an auxiliary two-speed gear on a vehicle, has two similar windings W in branch circuits including switches SW4, SW3 respectively closed by an output-driven governor above a predetermined vehicle speed, and by release of the usual accelerator pedal 34, the windings W being such that both must be energized together to actuate the relay switch 106, which latter then remains actuated by continued energization of either winding alone. Thus, upshift to direct- (or over-) drive requires accelerator release above the predetermined closure speed of the governor switch SW4, whilst return downshift does not occur on decelerating below the governor-switch opening speed unless the accelerator is partly depressed from its full release position to open the switch SW3. Accelerator kickdown shift is possible at any time by opening a kickdown switch SW5 in the common feed of both windings W, such feed also including the usual engine ignition switch SW1, and an upshift lock-out switch SW2. The two-speed planetary gear and its hydraulic control are the same as those in Specification 801,549.

Filed: 1941-05-14
Abstract: 549,991. Cellulose derivatives. DISTILLERS CO., Ltd., STAUDINGER, H. P., and HUTCHINSON, H. M. May 14, 1941, No. 6246. [Class 2 (ii)] A cellulose hydroxyalkyl ether containing 1-6 hydroxyalkyl groups to each three glucose units is homogeneously esterified by reacting it with a higher fatty acid chloride containing not less than 10 carbon atoms in the molecule, in presence of a tertiary organic base as catalyst. Esterification may be carried out at 80-135‹C. The organic base may be pyridine, methyl or ethyl or a methyl ethyl pyridine, e.g. 2-methyl-5- ethyl pyridine (aldehyde-collidine). At the end of the esterification, the reaction mixture may be treated so as to cause the reaction product to separate as a gel. This may be effected by raising the temperature to 150‹C. for a short time, or by adding a small amount of ferric or zinc chloride, or by hydrolysing a small portion of the residual acid chloride by the addition of water. The gel is removed and then the product is precipitated by or extracted with alcohol until free from the other constituents of the reaction mixture. In an example, cellulose hydroxyethyl ether is esterified with a mixture of lauric acid chloride, aldehydecollidine, and chlorobenzene. The product is soluble in carbon tetrachloride or benzene. The cellulose ether-esters obtained by the process are suitable for making films, foils, or sheets, or for impregnating or coating fabrics or other textile materials. Specification 358,510 is referred to.

Title: Improvements in or relating to optical projecting arrangements
IPC: G02B27/10
Filed: 1952-03-11
Abstract: 737,459. Kinematograph apparatus. COOK, G. H., and TAYLOR, TAYLOR & HOBSON. Ltd. March 9, 1953 [March 11, 1952], No, 6288/52. Class 97 (1). [Also in Group XL (b)] A double interlaced raster on a cathode-ray tube A, Fig. 1, is imaged on to a continuously moving film B by means of an objective C and a beam-splitting means H<SP>1</SP>, H<SP>2</SP> which provides light paths D<SP>1</SP>, D<SP>2</SP> displaced by the height of the raster and which are rendered operative alternately at picture rate by a shutter system F whereby the second interlaced scan is displaced with respect to the first in the direction of film movement so as to superimpose correctly on the same area of the film. The beam-splitting device is arranged to permit the whole aperture of the objective to be used and is constructed of an arrangement of prisms H<SP>1</SP>, H<SP>2</SP> with a semi-transparent reflecter H (preferably of the interference multi-layer film type) at the contacting surface of the prisms. An additional body of glass is provided on prism H<SP>1</SP> in order to provide equal length optical paths for the divided beams. The film moves through one frame height during the time of scan of one complete raster, and the height of the raster on the cathode-ray tube is reduced to one half normal whereby the area scanned on the film is restored to normal due to the film movement. The film and shutter system are driven in synchronism with the raster by circuit A<SP>1</SP> controlling motors F<SP>4</SP> and B<SP>2</SP>. The raster may be modulated by image signals so as to record television images on the film. Alternatively the raster may be unmodulated and serve to scan an exposed film for the purpose of generating signals in a photo-cell located beyond the film. A second embodiment, Fig. 4, utilizes a rotating disc J having half of its surface silvered and the other half transparent. The disc rotates in its own plane which is at 45 degrees to the objective axis. With this arrangement the shutter system may be omitted. The shutter F shown in Fig. 1 is in the form of a drum with slits F<SP>1</SP>, F2 ... which traverse the optical path in synchronism with the raster scan and are spaced apart the distance between axes D<SP>1</SP>, D2. An alternative arrangement, Fig. 3 (not shown), comprises an apertured cone with a vertex angle of 90 degrees rotating about an axis at 45 degrees to the objective axis. Other arrangements, Figs. 6-9 (not shown), comprise disc shutters. To ensure accuracy in the spacing of axes D<SP>1</SP>, D<SP>2</SP>, a parallel-sided plate which can be tilted to any suitable angle may be disposed in the path of one of the divided beams, Fig. 5 (not shown). Such a tilting plate can be utilized to compensate for any irregularity in the frame pitch of the film due to shrinkage. Specification 681,701 is referred to.

Abstract: 329,965. Colas Products, Ltd., Gabriel, L. G., and Blott, J. F. Feb. 27, 1929. Emulsions, making.-Aqueous emulsions comprising bitumen or oil and indiarubber are prepared by subjecting to agitation in a mixer, preferably a colloid mill, a mixture of molten or liquid bitumen and rubber latex, or oil and rubber latex, the emulsification being effected solely by the action of the latex, i.e., without addition of the usual dispersing agents. In an example, a stable emulsion of bitumen is formed by mixing in a colloid mill rubber latex having 33 <1>/3 per cent rubber content and molten bitumen of the type artificially produced from petroleum. The temperature of the latex is 50‹C and of the bitumen 130‹C. In another example, linseed oil is run through a colloid mill together with rubber latex containing about 33 per cent rubber. A small quantity of a stabilizing agent such as alkali caseinate may be added subsequently to the emulsification, or the emulsion may be coagulated by the well known methods to give a mass which is capable of being vulcanized. Specification 254,004 is referred to.
