Title: Improvements in mechanism for separating and feeding single sheets of paper, cardboard, or the like material, from a pile of sheets of the said material
IPC: B65H3/08
Filed: 1922-10-24
Abstract: 209,519. Rose, W., and Rose Bros. (Gainsborough), Ltd. Oct. 24, 1922. Sheet-separators; pile supports. - Sheets are separated and fed to wrapping, box-making &c. machines from the bottom of a magazine 1 on which the rear portion of the sheets are supported by a plate 4 and a roller 5, the plate 4 being formed with inclined parts 4<b>, 4<c> between which operates an oscillating sucker member 10 on an arm 8 operated from a cam 65 on a shaft 15. The front edges of the sheets are supported by ledges, on the points 17<a> of screws 17, these screws being arranged in the opposite front sides of the magazine when stiff sheets are being dealt with. The pivot 8<a> of the suction arm is arranged to the rear of the roller 5 so as to cause the front of the separated sheet to be pulled away from the front of the magazine so as to facilitate separation of the sheets, and to cause the sheet to conform to the bent parts 4<b>, 4<c> of the plate 4. The nozzle 10 of the suction device is connected to a pump 12<a> actuated from a crank 14 on shaft 15. and this suction is relieved as the sheet is taken by grippers 19, 44. Gripper mechanism; sheet-carriers.-The sheets are finally conveyed to the desired position by the grippers 19, 44 on an arm 18 which is oscillated by cam-and-lever mechanism from a cam on the shaft 15. The gripper 19 is similarly operated to close on the sheet, and to release the same after it has been advanced.

Title: Production of thermoplastic granulates
IPC: C08K11/00
Filed: 1964-07-15
Abstract: A method of producing fibrous thermoplastic granulates containing thermoplastic materials, fibrous materials and mineral filler materials from industrial waste waters, comprises mixing industrial waste waters containing fibrous materials and mineral filler materials with an aqueous thermoplastic dispersion at a pH of 7 to 8.5, said thermoplastic dispersion being formed by mixing a finely pulverized synthetic thermoplastic resin with a high molecular weight organic acid, and adding to the waste water mixture an aqueous emulsion of a softener and/or swelling agent for the synthetic resin so as to precipitate the thermoplastic synthetic resin, this mixture then being acidified by the addition of an aqueous solution of a polyvalent acid-reacting metal salt, filtered, and the filter cake dried and granulated.  The wastes may be derived from sludge concentrates from paper making and textile industries, and may contain mineral fillers and pigments such as kaolin and titanium dioxide.  Further organic or inorganic material in the form of long or short fibres may be added. Specified resins are polyvinyl chloride, copolymers of vinyl chloride with vinylidene chloride or vinyl acetate, and styrene/butadiene copolymers.  Emulsifiers such as soaps, alkali metal sulphonates and ethylene oxide condensates may be added to the dispersions. The preferred metal salt is aluminium sulphate. The emulsion may comprise dioctyl phthalate and a polyethylene oxide base emulsifier, optionally together with chlorinated paraffin wax.  Examples describe the preparation of mouldable granulates by adding aluminium sulphate solutions to aqueous dispersions comprising (1 and 2) cellulose fibres, kaolin, sodium hydroxide, polyvinyl chloride emulsion, dibasic lead stearate, stearic acid, sodium stearate and dioctyl phthalate emulsified with an ethylene oxide condensate, together with (3) iron oxide and titanium dioxide, (4) chlorinated paraffin wax, and (5 and 6) a butadiene/styrene co-polymer latex and carbon tetrachloride; and comprising (7) cellulose fibres, kaolin, sodium hydroxide, carbon tetrachloride, stearic acid, a butadiene/styrene copolymer latex and dioctyl phthalate emulsified with an ethylene oxide condensate.

Title: Process for the production of sulphur trioxide
IPC: C01B17/765
Filed: 1962-08-03
Abstract: Sulphur trioxide, which may be adsorbed to form sulphuric acid, is produced in a process wherein a sulphur idoxide-containing gas stream is combined with a pre-dried oxygen-containing gas stream, and the combined gas streams are passed through a catalytic conversion means to convert the dioxide to the trioxide, characterized in that the oxygen-containing gas stream is preheated by heat exchange in the catalytic conversion means before being combined with the other stream. In a preferred embodiment a gas stream containing 12-14% sulphur dioxide obtained by burning sulphur in a stream of pre-dried air is cooled from 2100-2300 DEG  F. to 900-1000 DEG  F. in a steam generation means, a second stream of pre-dried air is heated to 300-400 DEG  F. and combined with the sulphur dioxide-containing stream to form a combined stream containing 8-9% sulphur dioxide at 800-850 DEG  F., and this combined stream passes to a multi-stage converter, in the first stage of which the temperature rises to 1050-1120 DEG  F. after which the partly converted stream is cooled to 800-850 DEG  F. in steam generating means and passed to the following stages, where it is cooled by heat exchange with the second stream of pre-dried air.

Title: Preparation of n-acyltryptophan esters
Inventor: HOLLAND DAVID OLIVER
IPC: C07D209/20
Filed: 1951-12-21
Abstract: N-Acyltrotophan esters are prepared by treating an ester of a -acyl-b -(3-indolyl)-propionic acid with hydrazoic acid and sulphuric acid. The esters so produced may then be hydrolysed, preferably in alkaline solution to yield tryptophan.  In examples: (1) ethyl a  - aceto - b - (3 - indolyl) - propionate in chloroform is mixed with hydrazoic acid and added dropwise to a cooled stirred mixture of concentrated sulphuric acid and chloroform to yield N-acetyltryptophan ethyl ester, which upon hydrolysis with aqueous sodium hydroxide gives tryptophan; (2) as in (1) replacing the ethyl ester by the corresponding methyl derivative.  Reference is made to the N-benzoyltryptophan esters.  Methyl a -aceto-b -(3-indolyl)-propionate is prepared from methyl acetoacetate and gramine by condensation using sodium ethoxide, followed by treatment with methyl sulphate.
