Title: Improvements in the Extraction of Oil by Volatile Solvents.
Inventor: MACILWAINE ALFRED WILLIAM
IPC: C11B1/10
Filed: 1918-12-09
Abstract: 136,870. MacIlwaine, A. W., and Holdcroft, G. F. Dec. 9, 1918. Fatty oils, extracting by volatile solvents. The exhausted seed or meal is submitted to hydraulic pressure in a separate vessel to remove as much oil-bearing solvent as possible before steaming and drying. In the apparatus shown, the seed is run from the extractor A to an intermediate container B and fed through the funnel C and reciprocated feed-box C' to an hydraulic oil-press D. When the press is full, a plate D<1> is slid so that its solid portion closes the press, and the plunger D<2> is raised, the expressed oil escaping by the pipe d. The cake is removed by sliding the plate D' so that its orifice is in line with the barrel, and raising the plunger sufficiently to lift the cake into line with the feed-box C<1>, which, on its next reciprocation, pushes the cake on to breaking- rollers E. The meal is carried through a perforated steamer F', provided with a steam-jacket, by a conveyer and agitator F<2>, and through a steam-jacketed drier G by a conveyer G<1>. The container B, steamer F<1>, and drier G are connected to an exhauster and a solvent condenser. The container B may be dispensed with.

Title: Improvements relating to the conditioning of fibres for spinning
Inventor: STOREY JOHN BENNETT
IPC: D06M13/224
Filed: 1948-08-03
Abstract: Cotton, rayon staple fibres and other fibres spun by methods analogous to cotton spinning are treated, to facilitate spinning, with an emulsion of a colloidal solution of silica and an oil, the emulsion containing 7 to 25 per cent by weight of oil.  Preferably a vegetable oil (arachis or olive oil) is used, though a mineral oil or sulphonated mineral oil may be employed.  The colloidal solution of silica is preferably aqueous, and may contain between 5 and 20 per cent of silica by weight.  The preferred solution contains 15 per cent, and the quantity used may be such that from 0.1 to 5 per cent of silica by weight is deposited on the fibres. An emulsifying agent may also be added to the solution.  The emulsion may be applied at the carding stage, as the fibres leave the card as a sliver, at the drawing stage or elsewhere prior to spinning, and it may be sprayed on to the fibres.  In an example (all parts by weight), an emulsion is prepared from 100 parts of a 15 per cent colloidal solution of silica, 18 parts arachis oil, 32 parts water and 1.8 parts of an emulsifying agent.  The emulsifying agent is dissolved in the arachis oil, which is slightly warmed, and the solution slowly added to a mixture of the colloidal solution and water with vigorous stirring, giving a stable solution containing about 12 per cent of oil.  The emulsion is applied to a cotton sliver in the carding operation. Specifications 607,696, 634,125, 649,897 and 654,850, [both in Group III], are referred to.ALSO:Cotton, rayon staple fibres and other fibres spun by methods analogous to cotton spinning are treated, to facilitate spinning, with an emulsion of a colloidal solution of silica and an oil, the emulsion containing 7 to 25 per cent by weight of oil.

Title: Improvements in thermally-operated electric switches
IPC: H01H43/30
Filed: 1944-10-31
Abstract: 585,762. Automatic circuit-breakers ; thermal switches. OLSSON, G. D. Oct. 31, 1944, No. 21265. [Class 38 (v)] A time switch, especially for use on staircases and operated by short electric impulses, comprises a contact-operating spring restrained by a thin filament which is extended by electric heating to operate contacts which maintain a circuit energized whilst a bimetallic strip heats up and cools again. When a button 35 is pressed, a filament 32 is energized through the normallyclosed contact 9 and heats up rapidly thus allowing the spring blade 25 to move the lever 3 so as to release a blade 6 which then moves down to engage contacts 12 and break contacts 9, thus de-energizing the filament which rapidly cools. The contacts 12 light the lamps 34 and also energize, through contacts 10, a heater 40 for the bimetallic strip 7. At a predetermined temperature the strip 7 snaps upwards; owing to engagement of a roller 19 with the hump 20 on a spring- biassed lever 4, opening contacts 10 thus deenergizing the heater 40 and carrying the blade 6 into engagement with contact 9. The slot 17 thus allows the lever 3 to return to its original position. The strip 7 then cools and snaps back to its datum position breaking the lamp circuit at 12. If the button 35 is pressed again when the strip 7 is in its deflected position, the element is again energized and the lever 3 is moved to a greater extent until the strip 5 is freed from its detent surface 18. Subsequent cooling of the strip 7 pulls strip 5 down into the notch 17, strip 6 still engaging the side of the lever 3 and the heater operates again as above, so that the light remains energized for twice as long as before. The apparatus may also be operated by alternating current or a separate operating source.
