Title: Improvements in and relating to the manufacture of receptacles for organic liquids
IPC: B64D37/02
Filed: 1943-01-04
Abstract: Receptacles for organic liquids such as petrol tanks, pipes or transparent display receptacles for lubricating oil, are formed from a composition consisting of a cellulose ester and a plasticiser therefor, and have their inner surfaces saponified to such a degree that the walls are capable of resisting swelling and removal of the plasticiser when in contact with said liquid. Cellulose acetate is preferably used, but esters such as cellulose propionate, butyrate, acetate-butyrate, acetate-propionate or ether acetates may also be used; the plasticiser may comprise dimethyl phthalate, diethyl phthalate, dimethoxyethyl phthalate, dibutyl phthalate, methyl and ethyl phthalylethyl-glycollates, dimethyl or diethyl tartrate, triphenyl or tricresyl phosphate, diacetin, triacetin, glyceryl monolactate triacetate, trichlorethyl phosphate or mixtures thereof, 10 to 150 parts by weight of plasticiser to 100 parts of cellulose ester being preferably employed.  The saponifier used may be caustic soda or potash, alkaline vapours such as methylamine and ammonia, or aqueous solutions thereof, with or without, say, up to 25 per cent of a swelling agent for the esters, such as ethyl alcohol, or a solvent, such as acetone; after saponifying, the inner surfaces are preferably washed first with dilute acid such as HCl, and then with water, and finally dried as by warm air currents, or stoving at about 40 to 60 DEG  C.  The material may be backed or reinforced with one or more layers of fabric, such as cotton, rayon, wire, &c. and/or selfsealing layers of bullet-proofing material.  The receptacle may be built up of cellulose ester sheet or foil, or moulded from powder or granules. Examples are given. Specifications 20672/10, [Class 2], 391,669 and 541,371, and U.S.A.

Title: Improvements in sheet feeding mechanism
IPC: B65H1/18
Filed: 1945-01-04
Abstract: 581,829. Feeding sheets &c. AMERICAN TYPE FOUNDERS, Inc. Jan. 4, 1945, No. 338. Convention date, Jan. 4, 1944. [Class 100 (i)] Sheets are fed from a pile P to a machine by means of an oscillating suction separator F which transfers the sheets to grippers C on a feed chain c, and the pile board 20 is raised automatically when required by means controlled by the downward movement of the suction cup 114 towards the pile. The pile support is raised by means of a cord 25, Fig. 1, wound on a shaft 27 geared to shaft 32 which is operated by a ratchet 35 and pawl 41 on an arm 40 which is oscillated by a cam 45 when the arm is permitted to move towards the cam. Normally the arm 40 is held away from the cam by a link 125 and lever 126 connected to a piston in a cylinder 131 connected to a vacuum. When however, the suction cup 114 has to descend to a predetermined extent to contact with the top of the pile the vacuum is broken by means of a vent hole 140, Fig. 9, in the cylinder 75 of the separating device. A holding-device keeps the pile-raising means operative during'subsequent feeding operations until the maximum height of the pile is restored. The cylinder 75 is connected by a pipe 76 clamped to a tube 70 connected by a tube 83 to a box 84 which is connected to a suction pump and which can be vented by an aperture controlled by a valve 87 on a lever oscillated by a cam 90. The tube 70 and the cylinder 75 are carried by a spring-controlled quadric link system 64, 98, 96, Fig. 4, operated by a cam 101 acting on a roller 100 on an arm 99 attached to link 64. The suction cup is attached to a differential piston 110, 112, which is normally raised by a spring 116, the piston being moved against the action of the spring when the cup 114a contacts with the pile. The part 112 of the piston at its upper end has a flange 120 which is formed with an aperture 121, and an aperture 122 is provided at the top of the annular part of the piston. The downward movement of the piston is limited by a stop 123, and when this is reached the vent hole 140 releases the pile-raising gear described above. by causing withdrawal of a piston 145 from the position shown in Fig. 7 due to reduction of air pressure in cylinder 142 owing to opening of vent 140. A value 150, Fig. 7, is thus opened to connect cylinder 131 to atmosphere with consequent release of lever 40. A catch 158 on a lever 161 oscillated by a cam maintains the valve 151 open long enough to permit of adequate action of the pile-raising gear. In a modification, Fig. 14, the suction cup 114 is adjustably connected to a rod 167 which can separate electrical contacts 171, 172, 173, 174 when the pile is low and thus cause de-energisation of an electro-magnet which normally holds the pile raising pawl out of action. An auxiliary switch prevents energisation of the electromagnet until the pile is restored adequately. The invention is applicable to feeds in which the pile is advanced substantially horizontally on a conveyer band.

Abstract: 112,967. Campbell, D., and Goodyear, C. Jan. 12, 1917. Coke ovens.-The floor of a coke oven rests upon a permeable mass of finely divided material and is formed with uniformly distributed apertures for withdrawal of the distillation gases and with means for trapping and facilitating the remov.al of any dust or solid matter that may pass through the floor apertures. Fig. 1 shows a vertical section of an oven, taken through the centre of the charging aperture 3 and the coke discharging passage 5, and Fig. 4 shows a cross section and perspective view of a part of the oven floor. The floor 6 inclines uniformly towards the passage 5 to facilitate discharge of the coke, and is formed of rows of bricks 20 and 21, Fig. 4 resting upon rows of bricks 16 and 18 respectively; the bricks 16 are bedded upon the lateral parts and the bricks 18 upon the central parts of rows of tiles 15. From a shoulder 7, the inner wall of the oven drops vertically as shown in Fig. 1, and then slopes conically to a central wall 9, covered by a grating 10 and in communication with a gas-withdrawal pipe 12. The conical space is packed with gravel or pieces of rock and the upper part of the packing is covered with a layer cf fire clay upon which the tiles 15 are bedded The central parts of the sides of the bricks 21 are recessed above and bevelled inwards, as shown at 22, in Fig. 4, and the bricks 16 have their central parts recessed to form gas passages 17; the spaces between adjacent rows of bricks 16 are filled with gravel up to the recesses 17. The distillation gases pass through the openings 22 into the channels 19 between the bricks 18 and 16, and then through the passages. 17 and the passages 30 between the adjacent rows of bricks 16, and traverse the gravel packing before finally entering the discharge pipe 2; the sides of the bricks 20 overhang the sides of the bricks 16. Soot &c. is trapped in the channels 19, which are connected in pairs to passages 25, extending to the exterior of the oven and provided with a removable cover 26.

Title: Process for the manufacture of d-glucuronic acid
IPC: C07H7/033
Filed: 1930-01-07
Abstract: d-Glucuronic acid is obtained by subjecting vegetable gums, particularly acacia gum, to hydrolysis in an acid reacting medium. In an example, gum arabic is dissolved in 5 per cent sulphuric acid and maintained at 100 DEG  C. for about 10 hours, the completion of hydrolysis being determined by the absence of further change in the optical activity of the solution containing the operation.  The sulphuric acid is neutralized, first with baryta water and then with barium carbonate and the solution decolourized with carbon if necessary, is filtered and concentrated.  The barium salt of glucuronic acid is then precipitated by adding alcohol, the admixed sugars remaining in solution.

Title: Improvements in or relating to the production of electromagnetic oscillations
IPC: H01J25/74
Filed: 1939-01-09
Abstract: 528,041. Electron oscillators. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Jan. 9, 1939, No. 676. Convention date, Jan. 22, 1938. [Classes 39 (i) and 40 (iii)] In an ultra-short wave oscillator a stream of electrons flows through a single hollow resonator wherein is a field of standing electromagnetic waves ; this field accelerates or retards electrons in the beam according to their time of entry into the resonator relative to the standing waves, and as a consequence bunches them into groups. The bunched electrons are removed from the field; if this is effected as the field tends to retard the electrons then the latter give up energy to the field and maintain its oscillation, but if acceleration of the groups takes place as they leave the field the electrons abstract energy from the field and oscillation is stopped. The electric component of the standing waves is along the line of travel of the beam and is preferably stronger at the point of exit of the beam than at its point of entry into the resonator thereby increasing the efficiency of the oscillator. The resonator 23, Fig. 1, may be conical with grids 24 and 25 at its ends ; a cathode 21 and anode 27 form the stream. Energy may be withdrawn from the system by the loop 13. In a modification the standing waves are contained within the spherical shell 28 which carries at one end the cone 33 with small spherical head 29; the electrons from the cathode 26 pass through the grids 31, 32 to the anode 77 an insulating cylinder 76 restricting their path. The head of the sphere 29 could be solid the anode 77 being dispensed with. Two biasing batteries 22, 35 determine the time of flow of the electrons through the resonator, this time permitting bunching. An alternating bias from the supply 38 may be superposed on the D.C. voltage to vary the flow and the synchronizing of the bunching with the standing waves. It is stated that almost any form of hollow resonator will work according to the invention and simple cylindrical, conical, spherical and part spherical forms are described. In one form the indirectly heated cathode 46, Fig. 8, forms part of the end wall 41 which is insulated from the coned side walls 43 ; the bunched electrons are received by the end wall 42 and power is withdrawn by the loop 48. The Specification explains the working of this " monotron " by a mathematical exposition and shows how it is similar to but different from the " Klystron " described in Specification 523,712. It may be used in an amplifier or detector system as well as in oscillation producing. Specifications 516,750 and 517,264 also are referred to. The Specification as open to inspection under Sect. 91 also mathematically describes the working of the " Klystron." This subject-matter does not appear in the Specification as accepted.
