Title: Power erected accumulating conveyor
IPC: B65G47/26
Filed: 1963-04-22
Abstract: 1,036,466. Endless conveyers; roller conveyers. RAPIDS-STANDARD CO. Inc. April 22, 1963 [June 26, 1962], No. 15774/63. Heading B8A. Figs. 1, 2, 3 and 6 show an accumulating conveyer 10 comprising article supporting wheels 13 mounted on shafts 12 with an endless belt 15 continuously driven and carried by support assemblies 20 which may be raised to bring the belt 15 into article engaging position or retracted to disengage the belt 15 from the articles (not shown). Each support assembly 20 has a sprocket 28 engaged with teeth 29 on the underside of the belt 15, the sprocket 28 being mounted on an arm 25 pivoted about a shaft 24 and is provided with a ratchet 26 connected by a rod 35 to a sensing unit 43. Each sensing unit 43 is normally biased by a spring into a raised position so that the connecting rod 35 pulls the ratchet 26 into engagement with the teeth on the sprocket 28 preventing it from rotating freely so that movement of the belt 15 drags the support unit 20 from its retracted position (Fig. 3) into its raised position (Fig. 6) whereby the belt 15 is brought into driving engagement with articles (not shown) supported on the wheels 13. When a sensing unit 43 is depressed by an article the connecting rod 35 moves the arm 25 carrying the sprocket 28 counterclockwise so that the support assembly 20 is retracted and the belt 15 drops out of engagement with any article on the associated part of the conveyer so that if any article is obstructed the appropriate sensing unit 43 disengages the drive of the belt 15 from a following article. As the sensing units 43 are spaced along the conveyer with associated support assemblies 20 for the belt 15 articles successively come to a halt on the conveyer until the obstruction is cleared, release of a sensing unit 43 elevating the associated support assembly 20 so that conveying is recommenced. Figs. 10, 13 and 14 show an accumulating conveyer 80 with solid rollers 81 normally driven by engagement of an endless belt 15a raised by support units 20a. The support units 20a are raised and lowered by a rachet arrangement controlled by a sensing unit 43a in a similar fashion to that described above.

Title: Improvements in Carburetters for Internal Combustion Engines.
Inventor: FAGARD JULES
IPC: F02M3/12
Filed: 1916-11-04
Abstract: 103,627. Fagard, J. Nov. 4, 1916. Spray carburettors.-In a carburettor wherein a pilot or slow-running jet is fed from a separate open well through a depending tube, the fuel is admitted to the well at a point above the lower end of the depending tube. The pilot-jet a is fed through a tube b from the well c open to the atmosphere at d. Fuel from the passage e enters the well through a tube g, the outlet of which is above the lower end of the tube b. To facilitate starting, the tube b should descend as far as possible below the normal fuel level. During slow running, the supply of fuel to the well and to the pilot-jet depends upon the head H between the normal fuel level and the top of the tube g, by suitably reducing which, the comparatively large passage g gives the same effect as a restricted opening which is liable to become choked, although a restricted orifice may be placed in the passage e. In a modification, the passage g and tube bare formed in the walls of the well c. In a further modification, the tube g is replaced by an opening in the wall separating the well from the float chamber.

Title: Method of removing colloidal silver from a photographic element containing both colloidal silver and a developed silver sound image
IPC: G03C7/24
Filed: 1954-05-31
Abstract: 746,569. Photographic sound films;colour photography. KODAK, Ltd. May 31, 1954 [June 18, 1953], No. 16004/54. Drawings to Specification. Class 98 (2). Colloidal silver as of a light-filter or antihalation layer but not the developed silver of a silver sound track is removed from an element containing both of these by impregnation thereof with a fixing solution, subjection to the action of a silver bleaching agent until the colloidal silver but not the sound track has been bleached, and then immediately washing out the silver bleaching agent and subsequently removing the bleached silver. Colloidalsilver may be so removed from an image layer or a separate layer and the element may be of multilayer or mixed grain type. The process is particularly directed to the removal of a colloidal silver -filter layer without affecting a developed silver sound track in a multilayer colour film and so avoiding sound-distortion resulting from the use of a silver sulphide or silver plus dye sound track, thus a detailed example directed to the reversal processing of a conventional red, green and blue-sensitive film with a colloidal silver filter layer beneath the blue-sensitive layer specifies, after exposure of the sound and picture areas, with the latent sound track image in the top layer only or in the other sensitive layers as well; (1) black and white development and washing; (2) fixation in the sound track area only by edge application of aqueous hypo solution; (3) reversal re-exposure, colour development and washing; (4) saturation in the sound track area only or preferably throughout the film with aqueous hypo or an aqueous methanol solution of ammonia hypo for 15 or more seconds to render colloidal silver and very fine grained silver existing in the film as fog selectively bleachable; (5) application to the sound track area only but preferably throughout the film of a specified ferricyanide-bromide or a quinonehydrochloric acid bleaching solution for 15 Seconds or until the colloidal silver but not the image silver has bleached and washing; (6) fixation for 10 seconds or until the bleached colloidal silver has been removed; (7) bleaching as with the above bleaching solutions to convert the sound track silver and image silver to a silver salt such as silver halide; (8) treatment in the sound track area only by edge application of a specified fogging developer composition to convert the sound image back to silver and washing; (9) hypo treatment to remove silver salt from the picture areas and leave a silver sound track and dye picture images. In addition to this detailed example the Specification outlines the procedure in accordance with the invention when used in conjunction with methods involving the application of a resist material to the sound area of a film and refers to the use of such procedure in negativepositive processing. Specifications 488,108, 507,841, 524,154, 524,554, 524,555, 541,589 and 647,093 are referred to.

Title: Improvements in and relating to abrasive smoothing or polishing cloths, paper and the like, and methods of manufacturing the same
Filed: 1933-06-06
Abstract: Flexible abrading materials such as smoothing or polishing cloths, paper, or the like comprise abrasive material secured to a support by a layer of rubber-like materials, including rubber, latex, the form of latex known under the Registered Trade Mark "Revertex." or that known as "Revultex," guttapercha, balata, substitutes for rubber for example of a cellulose basis, and treated natural or artificial resins, this layer having a porous, for example, a spongy, structure. Aqueous rubber suspensions or dispersions such as latex may contain vulcanizing agents, and agents for accelerating vulcanization, or may be ready vulcanized. Previously coagulated products may be used alone or with the suspensions.  For rendering the material porous, known methods such as the addition of ammonium carbonate or hydrogen peroxide may be employed, and catalysts such as pyrolusite may be added. Modifying agents are ground quartz, chalk, heavy spar, and magnesium.  The porous layer may be applied over a non-porous rubber layer.  A method of producing an article comprises stirring into "Revultex" a mixture of quartz powder and silicon dioxide. To this hydrogen peroxide and an aqueous suspension of pyrolusite are added, the active mass then being poured on the support, dried, and if necessary hardened by heat.  Quantities of the materials are specified.  In another example, corundum and quartz are mixed with a mixture of cellulosetripropionate and methyl-ethyl-polyacrylic acid ester dissolved in benzene, alcohol and acetone.  Finely divided urea hydrogen peroxide and pyrolusite are then stirred in, and the mass is spread on the fabric.
