Abstract: 695,486. Filters. BRITISH FILTERS. Ltd., and HOBSON, A. G. Jan. 3, 1952 [Jan. 3, 1951], No. 259/51. Class 46 A filter, particularly for liquid fuel, comprising a head or support 1, Fig. 1, for mounting on a structure and a casing 8 enclosing a filtering element 7 in which securing means extending through the interior of the casing and through the head or support comprises two or more members 12, 14, engaged by screw-threaded connections, two of the members having operable parts such as bolt heads or nuts accessible from outside the casing and head respectively, at least one of the threaded elements is held against rotation so that release of either of the means enables the casing 6 to be removed from the head or support 1. The bolt 12 having a head 13 bearing against a block 10 secured to the base of the casing 6 is engaged in the extension 15 of a nut 14 which bears against a flat surface 16 of the head 1. Either or both of the members 13, 14 may be prevented from rotating by locking, caps 30 secured by screws 30a. Liquid entering the filter passes from annular chamber 5 through the element 7 to the central perforated tube 21 and leaves through channel 4. A resilient seal 25 enclosed by cover 26 is seated in the lower end of tube 21 by the spring 27 bearing thereon. A liquid retaining ring 19 surrounds the bolt shank. In a modification, Fig. 2, a long bolt 31 and a short one 32, having their heads engaging the block 36 at the base of casing 6, and the upper end of head 1 respectively, are engaged in a nut 33 which may slide without rotating by the co-operation of key-way grooves thereon with projections or splines on the head. The nut is rectangular in cross-section allowing liquid to flow to the outlet 4. Locking devices may be provided for the heads of the bolts as in Fig. 1. In a further form, Fig. 6 (not shown), a by-pass port in head 1 connecting the inlet to the outlet and normally closed by a spring-pressed ball valve may be opened when the differential pressure across the filter rises due to clogging of element 7. In another modification, the bolt heads are replaced by nuts and means are provided for preventing rotation of the bolt or bolts and two or more securing members may be provided. The filter element 7 comprises a spiral roll consisting of a metallic former 20 attached to the tube 21 and completely enveloped by felt 22, or a star section filter element of gauze or other material may be employed.

Abstract: 1,106,606. Endless conveyers. CONTINENTAL CAN CO. Inc. 3 Jan., 1967 [18 April, 1966], No. 354/67. Headings B8A and B8H A device for supporting cans 11 and like cylindrical articles for conveyance by a chain conveyer 20 comprises a support rod 23 attached at one end to the conveyer and having a plurality of radially extending fine resilient wires 45 axially and angularly spaced about the rod 23 to engage the internal surface of the cans. The wires are corrugated (Fig. 11, not shown) and are of a length to produce an interference fit with the cans and are thereby bowed in the direction of motion of the cans being placed thereover. The support rod is formed of two portions, a solid portion 33 with one end thereof acting as a pivot pin of the chain conveyer and the other end being attached to a twisted wire portion 42, the wires 45 are in mechanical interlock in the twists of the twisted wire portion.

Title: Improved process and apparatus for operating rotary kilns
IPC: F27B7/14
Filed: 1925-01-07
Abstract: 240,049. Fasting, J. S. Jan. 7, 1925. Rotary kilns.-In rotay kilns having internal plates, helical surfaces, worms, chains, ribs, or like projecting elements for lifting, conveying, or increasing the surface area of the material under treatment, a cooling medium is introduced to lower the temperature of the gases before they reach these members, thus saving them from rapid deterioration. The kiln 1 is provided between the calcining zone and the drying zone, with a transversely disposed pipe 2 open at its ends and having an aperture 3 facing the charging end of the kiln and closed by a valve 4 reguated by an external ring 6. A regulable flow of air into the kiln is thus caused which lowers the temperature of the gases before they reach the lifting plates 1<1>, 1<11>. The cooling medium may consist of cooled combustion gases from the chimney 11 or air which has been heated by radiation from the hot portions of the kiln; the ends of the transverse pipe 2 in these modifications opening into a stationary jacket surrounding the kiln and connected with a fan drawing gases from the chimney 11, or with a jacket surrounding the calcining zone and supplied with air. Pores, leakages and joints in the kiln lining may afford access for the cooling air. Specification 149,764 is referred to.

Patent GB-630892-A (GB)
Title: Improvements in the manufacture of siloxane resins
IPC: C08G77/00
Filed: 1947-01-07
Abstract: A siloxane is formed by co-hydrolysing and condensing a mixture of monomethyl-, monophenyl-, and methyl phenyl silicon derivatives, the other valencies of the silicon atom being satisfied by alkoxy, aroxy and amino radicals and halogens.  A solvent such as benzene or toluene, and an alcohol are preferably present in the hydrolysis step, together with a catalyst such as hydrochloric or oxalic acid. The mixture may then be heated to cause resinification.  Fillers such as metal, metal oxide or silicate, pigments and fibres may be incorporated, or the products may be dissolved in toluene or acyclic hydrocarbons.  In examples (1) five mixtures each containing different proportions of methyl tri-ethoxy silicon, phenyl triethoxy silicon and phenyl methyl diethoxy silicon are added to alcohol containing a small amount of benzol and aqueous oxalic acid, followed after heating at 60 DEG  C. by concentrated hydrochloric acid and after further heating by toluene; (2) mixtures containing different proportions of methyl-, phenyl, and methyl phenyl silicon chlorides are hydrolysed with water containing isopropyl alcohol and toluene. The product after removal of acid and solvents is heated with more isopropyl alcohol in toluene solution.  The products of both examples are moulded with asbestos as filler and a little calcium stearate, and heat cured for use, e.g. as brake blocks.

The roller and brake are mounted on a slidable part 19 which is initially displaced in a guide 18 on depressing the pedal to bring the roller 20 into engagement with the cable on two support rollers 16, stronger pressure on the pedal compressing the spring 24 to bring the brake 21 into contact with the roller 20 to lock the latter thereby causing the cable to move the trolley. The pedal 26 may be replaced by a screw device. For use on slight slopes the skids which engage the rails may be replaced by rollers or wheels. The trolley may be coupled to other trolleys for combined movement. The platform 11 is set at an angle to the skids equal to the mean angle of the track so that the platform will be substantially horizontal in use.

[Also in Division G4] In order to determine the angular position of a moving member a polygonal reflector having a number of peripheral outwardly-facing reflective faces disposed round its axis of rotation in a regular manner is coupled to the moving member so as to rotate about the same axis with it. A ruled grating 3 having a line separation d is illuminated by lamp 1 through lens 2. Light from the slots of the grating is made parallel by lens 8 and directed on to the polygonal reflector from whence it is returned through the lens to form an image in the plane of grating sections 4. There are four of these short grating sections each placed over a pair of photo-cells 16, 17 and located with a phase shift of 90‹ relative to their neighbours. The outputs of the photo-cell pairs are fed to a position indicating device 20. The number of faces on the polygonal reflector is made large (in a practical embodiment 360) and the grating line separation d corresponds to where f is the focal length of lens 8 and n the number of reflector faces.
