Title: Improvements in the manufacture and application of halogenated stearic acid esters
IPC: C07C69/63
Filed: 1935-07-08
Abstract: Dihalogenated esters of stearic acid are prepared (1) from an ester derived from stearic acid and an alkyl alcohol containing up to 18 carbon atoms, by treating the ester with chlorine or bromine in an amount sufficient to introduce two halogen atoms into the molecule, or (2) by chlorinating stearic acid to yield a dichlorostearic acid, and esterifying this with an alkyl alcohol containing up to 18 carbon atoms, or (3) by chlorinating an alkyl alcohol containing 5--18 carbon atoms to yield a dichloro derivative, and esterifying this with stearic acid.  Pure or commercial stearic acid may be used.  The products may be washed with dilute alkali, and may be stabilized by treatment with an oxidizing or reducing agent, preferably in alkaline solution; if a reducing agent such as sodium sulphite is used, the products should first be blown with air, to remove free halogen. Addition of a salt solution to the alkali used in washing or stabilizing is advantageous, to avoid emulsification.  The purified and stabilized products may then be washed with water, dried and, if necessary, clarified by treatment with fuller's earth, kieselguhr, active carbon or silica gel.  The products are useful as lubricants and as additions to hydrocarbon lubricating oils. Specified products are methyl, ethyl, propyl, butyl and octadecyl dichlorostearate. Specification 422,956, [Group III], is referred to.ALSO:Dihalogenated esters of stearic acid, useful as lubricants and as additions to hydrocarbon lubricating oils, are prepared (1) from an ester derived from stearic acid and an alkyl alcohol containing up to 18 carbon atoms, by treating the ester with chlorine or bromine in an amount sufficient to introduce two halogen atoms into the molecule, (2) by clorinating stearic acid to yield a dichlorostearic acid, and esterifying this with an alkyl alcohol containing up to 18 carbon atoms, or (3) by chlorinating an alkyl alcohol containing 5--18 carbon atoms to yield a dichloro derivative, and esterifying this with stearic acid.

Title: Cellular thermoplastics tubes
Inventor: EDNEY GEOFFREY JOHN
IPC: B29C44/22
Filed: 1968-04-25
Abstract: 1,270,263. Plastics pipes. BAKELITE XYLONITE Ltd. 22 April, 1969 [25 April, 1968], No. 19629/68. Heading F2P. A tube of cellular thermoplastics material such as low-density polystyrene, has at least a part of the material of the outer wall portion b of a lower density than that of an inner portion a of annular cross-section. Preferably the lowdensity cellular polystyrene has a density of from 3À5-5À5 lbs. per cubic foot. As shown, the cellular plastics material of density a is heated on its outer surface to provide the less dense layer b which serves as a cushioning layer. Further applied heat provides a weaker tube in that the layer b becomes thicker and the layer a narrower. Still greater application of heat gives cell collapse at the outer tube surface to provide a high density outer skin (c), Fig. 4 (not shown). The heating, which may be carried out imniediately following, or at some time later than, the extrusion of the thermoplastic plastics tube, may be carried out by passing a hot zone along the tube or by passing the tube through a hot zone, the tube being cooled, if necessary, after the extrusion process. Exterior profiles, such as fluting, can be provided on the tube, by printing a polarizable coating on the tube and then placing it in an oscillating magnetic field to produce localized expansion beneath the coating. Alternatively, the printed coating may be an infra-red absorbtive coating. The profiles may, instead, be formed by heating the tube in a suitably shaped mould.

Title: Improvements in or relating to servers for icecream and the like
IPC: A23G9/28
Filed: 1936-07-15
Abstract: 477,622. Ice - cream servers. NEWTON, T. H. July 15, 1936, No. 19636. [Class 28 (i)] [Also in Group V] A device for making ice-cream wafers comprises a mould 10 the base of which is apertured at 12 for the passage of end flanges 15 of a member 13 which supports the bottom plate 18 of the mould, the side flanges 16 of the member 13 being arranged to slide externally of the mould. The base of the member 13 has a central opening which slides over the handle 11 of the mould 10. The member 13 is retained in a position of adjustment, according to the thickness of the ice-cream wafer to be produced, by a ring 20 having an inwardly projecting pin engaging in interconnected grooves in the handle, a ring 21, likewise associated with the grooves, being brought to bear against the ring 20 to lock it in position. The ejection of the finished wafer is effected by sliding the member 13 upward over the handle. The plate 18, as shown, is slidably removable from the member 13, or alternatively, is hinged thereto, to permit the device to be disassembled for cleaning. Instead of interconnected grooves in the handle, series of rigid studs, each series being spaced along the handle, may be provided. The ring 20 is slotted to corresponding with the stud arrangement, so that when the slots and studs are aligned, the ring is movable longitudinally on the handle. Alternatively, instead of fixed studs, spring-pressed studs or balls may be provided. A number of upstanding elements on the member 13 may be arranged to pass through corresponding openings in the mould base, in which case the biscuit rests upon the elements, the plate 18 being dispensed with. Fig. 9 shows a device for moulding ice - cream for insertion into a wafer cone. The bottom plate 27 of the mould 25 is carried by rods 33 passing through holes in the mould base and releasably connected to an annular disc 34 having keyhole slots in which the ends of the rods are engaged. One rod 33 is surrounded by a sleeve 35 having a helical groove which is engaged by a projection 37 on the base of the mould or on the handle 26. Longitudinal motion of the ring 34 on the handle produces corresponding movements of the rods 33 and plate 27, and a rotation of the sleeve 35 which is transmitted by gearing 38, 39 to a scraping blade 41 journalled at 40 in the plate 27. Sticking of the ice-cream to the plate, during ejection, is thereby prevented. The blade 41 and its operating mechanism may be dispensed with, and the rods 33 may be screwed to enable the disc 34 to be secured thereto between nuts. The . effective depth of the mould may be varied by selecting from a number of subsidiary discs having central stems of different lengths, the selected subsidiary disc being placed on the disc 27 so that its stem projects through, and is held in, a keyhole slot in the disc 27. The inward movement of the disc 27 is thus limited by the stem abutting against the floor of the mould.
