Title: An improved filter
IPC: B01D35/14
Filed: 1944-07-07
Abstract: 576,999. Filters. PUYDT, F. A. De. July 7, 1944, No. 13025. [Class 46] A filter for oil or other liquids comprises a casing 12 within which is a receptacle 19 for filter elements 23 of cotton waste or like material separated by discs 24, each element being ejected in turn from the receptacle as it becomes clogged. The elements are ejected by means of a plate 18 on a shaft 16 turned by a handle 17, the shaft being screwed into the cover 15 for the casing 12. The receptacle 19 is supported by a plate 20 which divides the casing 12 into two parts, the lower part receiving the liquid to be filtered and the upper part having an outlet pipe 37 for filtered liquid. The liquid before filtration enters a heat-exchange casing 26 from which it is pumped through a coil 32 and pipe 35 into the casing 12. The coil 32 is placed in a housing 33 containing liquid heated by an electric heater 34. If the oil is at too low a temperature to pass through the filter elements it is returned through pipe 36 and a by-pass valve 29 to the pump for re-circulation. The filtered and heated liquid as it flows out through a coil 38 in the casing 26 gives up heat to the incoming liquid. The casing 12 has a detachable base-plate 14 for the removal of spent filter elements and sludge. Two complete filters may be arranged so that one can be in operation while the elements in the other filter are being replaced.

Title: Improvements in or relating to the manufacture of diaphragm-sealed closures for containers
Inventor: GEE HERBERT LEONARD
IPC: B65B7/01
Filed: 1965-03-29
Abstract: 1,080,184. Container closures. GEE MANUFACTURING CO. Ltd. March 28, 1966 [March 29, 1965], No. 13124/65. Heading B8T. [Also in Division B6] A closure member for a container, comprising a frangible diaphragm sealed on to an open frame X which may be fitted on to the open end of a container, is made in apparatus including a punch 14 which co-operates with a fixed cutting ring 16 to cut a suitably shaped blank Y<SP>1</SP> from a web Y of diaphragm material. The punch 14 is heated electrically, and seals the blank Y<SP>1</SP> on to a positioned frame X by pressing the blank on to the frame and either heatsealing it thereto in the case of heat-sealable material, or activating heat-sensitive adhesive on either the blank Y<SP>1</SP> or frame X and thereby sticking the two parts together. The web Y is fed under a guide plate 26 above the cutting ring 16, prior to cutting, and the frames X are fed into position along a channel 28 by means of a pusher on a rod 54, operated by a cylinder (50), Fig. 4 (not shown). Pins 34, Fig. 2, on a plate 36 locate the frame X below the punch 14, and are retractable by means of a cylinder 38 to enable the finished closure members to be removed. The punch 14, mounted on the upper plate 12 of a press, carries in the centre of its leading face a spring-biased plate 40 on a shaft 42, corresponding in size to a raised portion of the frame X, so that when the punch 14 is operated to cut a blank Y<SP>1</SP> and press it down over the frame X, the central plate 40 yields, Figs. 3, 5 (not shown), to shape the blank Y<SP>1</SP> into contact with the frame. The plate 40, Fig. 2, also prevents a finished closure member from adhering to the punch 14 when the punch is raised again prior to forming the next blank, and it is arranged that the upper end of the shaft 42 carrying the plate 40 receives a downward impulse by contact with a fixed member to displace the closure member therefrom. The completed closure member may then be discharged to a shoot by means of an air blast. Operations of the press and cylinders (50), 38, and the feed of the web Y, are in timed sequence. The diaphragm material may, for example, be of plastics material or coated paper or foil &c., and the frame X may be of metal or plastics material, or a combination thereof. The diaphragm may be sealed to the frame only at selected points, rather than over the whole contact surface.

Title: Improvements relating to the isolation of germanium
IPC: B01J41/04
Filed: 1960-04-13
Abstract: Germanium values are isolated from dilute solutions in hydrochloric acid by passing the solution through a selective ion exchanger which contains as a structural unit a fluorone derivative of the formula:- <FORM:0937414/III/1> p  where R is a hydroxyphenyl with 1 or 2 -OH groups, said ion-exchanges having been prepared by condensation of said fluorone derivative with formaldehyde with or without an admixture of monobasic or dibasic phenols; thereupon treating said ion-exchanger and the adhering germanium with pure concentrated hydrochloric acid to remove the impurities, desorbing said ion-exchanger by washing with distilled water, and removing residual HCl from the solution so obtained, for example by electrolytic anodic oxidation.  By evaporating the HCl solution pure GeO2 is obtained. This electrolysis may be carried out in a cell which has joint anode and cathode chambers, the whole of the chlorine being evolved on the anode, and the germanium partly separating on the cathode in elemental form and partly remaining in solution.  Alternatively the electrolysis may be effected in a cell in which the anode and cathode chambers are separated by a semi-permeable membrane consisting of an anion exchanger, the anode chamber being filled with the desorbate and the cathode chamber with a dilute solution of ammonia, the chlorine being completely evolved at the anode and the whole of the germanium remaining in solution.

Title: Improvements relating to automatic machines for weighing loaves of bread or other like articles or packages
IPC: B07C5/20
Filed: 1932-05-07
Abstract: 395,484. Sorting by weighing. SOUTHALL & SMITH, Ltd., SOUTHALL, C., and WEAVER, F. W., Villa Street Works, Hockley, Birmingham. May 7, 1932, No. 13249. [Class 143.] An automatic machine for checking the weight of loaves of bread, package &c. comprises a conveyer a on which the loaves &c. are carried, a reciprocating slide q by which the loaves are moved individually from the conveyer to the platform c of a weighing machine, a second slide u under the control of the weighbeam b for moving the loaf off the platform in a direction parallel to the conveyer on to a stationary support t, and a third slide x for moving the loaf from the support t back to the conveyer, means being provided to prevent operation of the second slide u when the loaf is of light weight. A barrier n obstructs the loaves to detain them whilst the slide q pushes them on to the scale pan. When the barrier is raised to allow the loaves to be carried forward, an electric contact on the barrier is opened to break the supply circuit and suspend the checkweighing operations. The weighbeam is clamped against movement by any convenient mechanism whilst a loaf is being moved on to or off the weighing platform. If a loaf of light weight is pushed on to the platform, the platform rises and closes the circuit of a solenoid which liberates a catch and prevents the operation of the slide u, the rejected loaf being pushed down a shoot v by the arrival of the next loaf. Loaves of sufficient or over weight prevent the rise of the weighing platform and energization of the solenoid, and are passed in the normal manner to the support t and conveyer. The slide u when not rendered inoperative by the solenoid is operated by a spring and cam mechanism. The arrangements may be duplicated, a weighing device being provided at both sides of the conveyer, the slide q in this arrangement moving the loaves on to each weighing device alternately.
Patent GB-143392-A (GB)
Title: Improvements in and relating to the production of benzoic acid
IPC: C07C51/16
Filed: 1919-05-27
Abstract: 143,392. Thompson, W. P., (Etablissements Poulene FrÞres, Senderens, J. B., and Aboulenc, J.). May 27, 1919. Benzoic acid is prepared by oxidizing toluene with manganese dioxide and sulphuric acid at 60- 70‹ C. The process is carried out in a closed vessel A provided with an agitator K and connected to a gas-meter C. The charge of toluene is placed in the vessel, and the manganese dioxide and sulphuric acid is added gradually, the temperature being carefully regulated by running cold water through the double bottom of the vessel. Too high a temperature causes decomposition of the toluene or benzoic acid, with evolution of carbon dioxide, which is indicated by the meter C; the temperature is accordingly regulated so that the evolution of gas is kept as small as possible. The product is finally run off and suitably purified. Specification 22121/97 is referred to.
Patent GB-133096-A (GB)
IPC: F02K9/94
Abstract: 133,096. Goddard, R. H. Feb. 27, 1918. Machine guns.-Relates to rockets embodying an automatic gun by which the rocket is propelled during flight by a succession of explosions produced by blank cartridges fed automatically from a magazine into a rearwardly-directed barrel. According to the present invention, the cartridges 43, Fig. 1, are fed alternately from diametrically opposite ends of the magazine 65 by means of a reciprocating slide 74 with two split tubes 72, 73, which receive the cartridges from the magazine through a pair of tubes 70, 71, and carry them over to the barrel 31. The cartridges are then pushed down gently by a hinged spring arm and finally pushed home by a breech-block 40. The first cartridge is fired by a fuse 64 from a priming ring 62 which also fires initial charges 63. The explosion of the cartridge causes the barrel to recoil slightly against a spring 37, and the breechblock to recoil further to open the breech and actuate the cartridge feed mechanism. The succeeding cartridges are fired by a firing-pin arranged within the breech-block. A shrapnel shell 53 is mounted over the breech-block and adds its weight to it. This shell is exploded by a time fuse adjusted by the rotation of a pin 130 about the axis of the shell by means of a cage 131, with a groove 131<a> for the pin, connected by a bracket 132 to a rotatable cap 133. When the last propellant cartridge is fed into the barrel, the return of the breech-block is slowed down by a dash-pot 136, Fig. 24, which is swung into the path of the breech-block. This slowing down prevents the firing-pin acquiring sufficient energy to fire the cartridge. The cartridge is then fired by the flash from the bursting shell 53 through a hole in the breech-block.

Patent GB-440539-A (GB)
Title: Production of nondecyl oxygenated compounds
IPC: C07C45/72
Filed: 1935-05-04
Abstract: Ethylhexaldehyde is condensed with ethylnonenone to give an unsaturated nondecyl ketol.  This is acidified and heated to yield a nondecyl ketone which is hydrogenated forming a nondecyl secondary alcohol.  A sulphate ester of the latter is obtained by the action of a sulphating agent at low temperature. Ethylhexaldehyde and 5-ethylnonene-3-one-2 are condensed in the presence of alkali, preferably below 40 DEG  C.  The resultant ketol is made acid to phenol phthalein with sulphuric or other inorganic acid, the product filtered and distilled in vacuo to form the ketone, having the apparent formula <FORM:0440539/IV/1> , and to separate unreacted reagents and water.  Hydrogenation is effected, preferably in the liquid phase, at superatmospheric pressures of 1 to 100 atmospheres and at 20--200 DEG  C. in the presence of a catalyst, e.g. active nickel, platinum or copper.  A saturated di (ethylheptyl) ketone is first produced and finally di (ethylheptyl) carbinol, probably <FORM:0440539/IV/2> This is filtered and fractionally distilled at subatmospheric pressure to separate the alcohol.  Treatment with, e.g. concentrated sulphuric acid gives the hydrogen sulphate ester which is neutralized with alkali or alkaline earth metal compounds or nitrogenous bases such as ammonia, alkylamines, or substituted amines such as triethanolamine.  The sodium sulphate ester is used as a detergent and a wetting, foaming, emulsifying and impregnating agent in the textile, leather, and other industries. In an example, the initial condensation is effected by slow addition of a methanolic KOH solution with agitation at about 30--50 DEG  C.  The ketone obtained by distillation, after addition of 5 per cent of its weight of active nickel, is subjected, while agitated, to hydrogen at 900 lbs./sq. in. at about 150 DEG  C.  The nondecyl alcohol may be produced from the undecyl ketone formed by condensing ethylhexaldehyde and acetone for example by adding methanolic KOH to the mixture maintained at 20 DEG C. and agitating for 26 hours, acidifying and fractionally distilling. Sulphonation of the alcohol is effected, according to an example, by addition of chlorsulphonic acid in dichlorethyl ether to the nondecyl alcohol dissolved in the same solvent at about 0 DEG C., nitrogen being blown through.  The product is neutralized with aqueous caustic soda and water added to extract the sodium sulphate ester, the extract being evaporated at a pressure below 100 mm. and at 60 DEG  C.  Concentrated sulphuric acid with or without acetic or other anhydride can be used for sulphating.  For example, equimolecular quantities of the acid and acetic anhydride are mixed at 10--15 DEG  C. and the nondecyl alcohol added slowly at 5--10 DEG C.  The product is poured on cracked ice, neutralized with caustic soda, and made alkaline with solid Na2CO3.  A light froth separates, which is purified, in the same way as the residue obtained by evaporating the aqueous layer, by extracting with methanol, diluting with water and extracting with hexane or like petroleum hydrocarbon.
