Title: Improvements in or relating to methods of distilling and/or purifying fatty acids and the products resulting therefrom
IPC: C11C1/10
Filed: 1933-06-29
Abstract: <PICT:0408117/III/1> Higher fatty acids, e.g. oleic, stearic acids &c. are distilled from stock containing them, e.g. palm oil or greases split by the Twitchel process by passing the stock while warm through a line 1, condenser 2, heater 4, and line 5 into a pool of acid on the upper plate 7<a> of a vacuum tower 6 heated by superheated steam supplied from a heater 14 through a pipe 15.  The plates 7 are maintained covered by pools of fatty acid so that the stock flows downwardly through pools of fatty acid successively higher in temperature and lower in fatty acid content.  The vaporized fatty acids pass off through a line 10 and the condenser 2 to a separator 28 where part of the vapours are condensed by water sprayed through a pipe 27 and separated, while the residual vapours are condensed in a condenser 43 and collected in a receiver 32.  Residual stock is removed to a pitch pot 13.  The condensates from the receivers 28, 32 are drawn off through lines 29, 35 by a pump 37. The stock is preheated to 250--400 DEG  F. in the condenser 2, and to 440--500 DEG  F. in the heater 4 while the still 6 is maintained at 590--660 DEG  F. under a vacuum of 20--24 inches.

Title: An improvement in or relating to the preparation of material for making bricks and the like
IPC: B28C9/00
Filed: 1933-07-01
Abstract: A reservoir or blending chamber is interposed between the grinding apparatus and a mixing machine or pug mill in plant for the manufacture of bricks and the like from shale.  This chamber is of such cubic capacity in relation to the flow of material and contains stirring or mixing devices of such a character that, under ordinary working conditions, material entering the chamber is reduced to uniform condition before leaving it and a uniform product is obtained.  The chamber may comprise an open-topped circular pan of suitable size having mounted axially therein a shaft provided with two spaced series of radial arms with radial or curved blades, the blades of the upper series being disposed at opposite angles or reversely curved to those of the lower series. The shaft between the blades may be provided with short blades to form an interrupted screw-thread to raise the material into the path of the upper series of blades.  The inlet and outlet are arranged circumferentially so that the material is continually traversed towards and away from the centre of the pan and at the same time is carried slowly around it. The supply of water to the pan may be regulated in accordance with any desired moisture content.  In an alternative construction, one series of blades may be mounted on a sleeve in which a shaft carrying the other series of blades rotates, either in the same or in an opposite direction to the others.  In a further form, a single set of arms and blades only may be provided, an inlet being arranged near the periphery and an outlet near the centre, or vice versa.

Title: Improvements in methods of and means for controlling the discharge of sludge from rotary centrifugal separator bowls
IPC: B04B1/16
Filed: 1963-05-13
Abstract: 969,179. Centrifugal separators. M. BARAM, May 13, 1963 [May 17, 1962], No. 18779/63. Heading B2P. A centrifugal separator bowl having a peripheral sludge discharge slot 3 is provided with at least one annular flexible sealing member 4 or 4a arranged wholly or partially in an annular groove 8 or 8a communicating with the slot so that it can be caused by fluid pressure to change its shape for opening or closing of the slot. The sealing member may be made of rubber or synthetic plastic. The annular groove 8 or 8a communicates with vents 7. In Fig. 1, the sealing member 4, when not subjected to centrifugal force, does not seal the slot 3 ; when subjected to centrifugal force it closes the slot and when the pressure of the liquid acting on the sealing member due to centrifugal force rises sufficiently, the sealing member is deformed and allows the sludge to escape. In Fig. 2, a U-shaped member 4a is sealingly anchored at an angle in the groove 8a and liquid injected into a recess 10 is led through passages 9 to the groove 8a to expand the member 4a so as to close the slot 3. When the supply of liquid is stopped, the liquid present in the groove is evacuated through the vents 7 and the member is deformed to open the slot. In Fig. 3a, a channel-shaped member 4A is provided with a protective cover R lying freely on, or secured to, the top of the member and the supply of liquid to the passages 9 may be effected through a boring in the spindle 6 of the bowl. The sealing members of Figs. 1 and 2 may also be provided with a protective cover.

Abstract: 665,940. Photo-mechanical printing surfaces. FRANK, L. July 20, 1950 [July 18, 1949], No. 18823/49. Class 98 (ii). A machine for photographic reproduction of patterns or designs on rollers as of copper comprises jacks supporting the ends of a mandrel carrying the roller at an adjustable height, a transparent cover to pass over the roller and hold a transparency of the pattern or design thereon, clamps beneath the roller for holding the ends of the transparent cover, and means for simultaneously raising the jacks to apply resilient pressure to the roller for tensioning the cover. The mandrel ends may be carried on rollers in the jacks to allow free turning and prevent uneven tensioning of the cover; and the jacks may be raised by rack and pinion mechanism acting through springs or by hydraulic means giving equality of tension. As shown, the mandrel ends b of roller c are carried by rollers d at the tops of jacks a; the transparent cover is clamped by a pair of bars in channel members, the front one of the pair being shown at m; hand wheels o on columns p are provided to give a preliminary tightening of the cover by raising jacks a and then the latter are further raised under uniform tension by operation of handle x to turn shaft w and hence a pinion v for each jack which raises racks u acting through springs (not shown) on the lower ends of the jacks. Ratchet mechanism y, z releasable by foot pedal 2 is provided to hold the jacks in the positions they have attained by manipulation of handle x. The Provisional Specification indicates, also, a method of raising the jacks simultaneously by use of two cams on a common shaft turned by a handle.

Abstract: A rubbery copolymer of an isoolefin and a multiolefin with or without an aromatic olefin is reacted with a minor proportion of one or more non-metallic aromatic selenenyl halides or nonmetallic aromatic sulphenyl halides, the reaction product containing up to 1 molecule of the combined halide per double bond in the copolymer.  The sulphenyl halide may be benzenesulphenyl, biphenylsulphenyl, naphthalene sulphenyl, anthracenesulphenyl, anthraquinone sulphenyl, benzothiazolesulphenyl or triphenylmethane sulphenyl chlorides or bromides and the aromatic nucleus may also contain the following groups: nitro, halogen, hydroxy, nitroso, chlorosulphone, alkyl, carboxyl, acetamido or amino groups.  The selenenyl halide may be a nitro-substituted benzene-or anthraceneselenenyl chloride or bromide.

The rubbery copolymer may be butyl rubber and may be a copolymer of isobutylene or 2-methyl-1-butene with isoprene, butadiene, piperylene, dimethylbutadiene, dimethallyl, cyclopentadiene, cyclohexadiene or allo-ocymene.  The copolymer may also comprise a third aromatic monomer component such as styrene, alpha-methyl styrene, p-methyl styrene, indene, dihydronaphthalene, p-chlorostyrene, dichlorostyrene or mixtures thereof.  The halidemodified copolymer may be vulcanized by forming a composition for example with stearic acid, zinc oxide, sulphur, fillers such as carbon black, accelerators such as thiuram sulphides and dithiocarbamates and other curing agents such as quinone dioximes, nitrosobenzenes, polyamines, guanidine derivatives, glycols, isocyanates and diisothiocyanates.  Cements may be prepared by forming an aqueous latex of the halide-modified copolymers and diluting with a polymer solvent such as hexane, beptane, benzene, naphtha, mineral spirits, or mixtures.  The cements may also comprise zinc oxide, carbon black, hydrated silica, sulphur, accelerators, oxidising agents, phenolic aldehyde resins, hydrocarbon plasticizer oils, esters and tars.  The cements may be used to form rubber-rubber and rubber-metal bonds.
