Title: Process of recovering liquid solutes from non-aqueous solutions
IPC: B01D15/00
Filed: 1922-02-22
Abstract: Consists in adsorbing a solute from a non-aqueous solution by means of a porous material having pores of a suitable size.  The substance adsorbed may be afterwards liberated in any manner, as by passing air over the material, subjecting it to reduced pressure, or by heating it.  A suitable porous material is defined as a substance which will adsorb not less than 10 per cent of its initial weight of water at 30 DEG  C. and a partial pressure not exceeding 22 mm. of mercury.  In a system having a number of components, the component most adsorbed is that which exhibits the smallest surface tension towards the adsorbing material.  The extent of the adsorption is also influenced by the difference in density between the components, the smaller this difference, the greater the adsorption of one of the components.  In examples, acetic acid is adsorbed by silica gel from a solution in benzol and butyric acid from a solution in gasoline.  A further example of a suitable absorbent is highly activated cocoa-nut charcoal. Specifications 24667/10 [Class 14 (ii), Beverages &c.], 136,543 [Class 1 (i), Chemical processes &c.] and 163,505 are referred to.

Patent GB-781416-A (GB)
Title: Process for curing polyepoxides
IPC: C08G59/68
Filed: 1956-02-22
Abstract: The curing of polyepoxides with a polycarboxylic acid anhydride is effected in presence of an organo substituted phosphine, arsine stibine, or bismuthine as activator; thereby enabling the polyepoxide to be cured at room temperatures and very quickly at elevated temperatures.  Suitable activators are trioctyl phosphine, diphenyl cyclohexyl phosphine, trihexenyl phosphine, trixylyl phosphine, triethyl phosphine, cyclohexyl phosphine and similarly substituted arsines, stibines and bismuthines.  About 0.8 to 1.5 equivalents of the anhydride are used per polyepoxide and from 0.1-4 per cent of phosphine by weight of resin.  The polyepoxide is liquefied before admixture with the anhydride and phosphine by melting or by solution in acetone, dibutyl phthalate, or liquid monoepoxy compounds, e.g. glycidylallylether or cyano-substituted hydrocarbons, e.g. acetonitrile; mixtures of liquid and solid epoxides may be used. The cure may be effected at 15-20 DEG  C. or rapidly at 50-110 DEG  C., examples of polyepoxides used are epoxidized triglycerides, epoxyethers of polyhydric phenols or alcohols, glycidyl ethers of novolak resins, glycidyl ethers of polyhydricphenols having two hydroaryl groups separated by an aliphatic chain of at least 6 C atoms, e.g. those derived by condensing phenol with cardanol and like phenols having an unsaturated side chain; polyepoxides reacted with polyhydric alcohols, polyepoxides from diglycidyl phthalates and like polybasic acids; polymers of allyl glycidyl ethers.  In examples: 100 parts polyallylglycidyl ether, 100 parts hexahydrophthalic anhydride and 3 parts triphenyl phosphine were poured into a metal cup; after standing 18 hours the mixture set to form a hard casing; on heating to 50 DEG  C. the mixture set in 6 hours.

Patent GB-934019-A (GB)
Title: Die forging press
IPC: B30B1/26
Filed: 1962-02-13
Abstract: 934,019. Forging presses. EUMUCO A.G. FUR MASCHINENBAU. Feb. 13, 1962 [Feb. 13, 1961; July 25, 1961], No. 5568/62. Class 83 (4). In a crank operated die forging press having a ram the mid stroke height of which may be varied, the ram is driven by a driving wedge which slides transversely of the press in an upper portion of the machine frame, the driving wedge being driven by the press crank. As the wedge 17 is moved to the right in Fig. 1 by the crankpin 15 and connecting rod 16, it also moves downward through reaction against a fixed sloping abutment 22 on the press frame 1, thereby forcing the ram 3 vertically down. The sliding face on the ram 3 and fixed abutment 22 are provided with guide rails 28, 27 (see also Fig. 2) which retain the driving wedge 17. Any play between these sliding surfaces due to clearance being taken up by the weight of the punch is obviated by means of a pair of pneumatic or hydraulic units 25, 26 which constantly urge the ram upwards. Drive to the crank is derived from a motor 6 which drives a shaft 8 carrying two flywheels 9 and a clutch 12 through gears 10 and 11. The opposite end of the crankshaft carries a conventional brake 14. Ejectors are provided in both the punch and die. The punch ejector 30 is operated by a cam surface 29 in the driving wedge (Fig. 1) and the die ejector (Fig. 2) is operated by a disc cam 33 mounted on the crankshaft and operating the ejector 32 through a linkage 34, 35. The stroke adjustment enables the height of the stroke above the die to be varied, the stroke itself being of fixed length. An eccentric bearing shell 38 is provided in the connecting rod crank bearing, and for initial setting it is rotated through bevel gearing 43, 44 turning a worm shaft 41. Superimposed on this initial setting movement of the eccentric bearing shell 38 is a second adjustment which causes the ram to be advanced toward the die by a predetermined amount for final sizing of the forging. The initial setting is made with the wedge 47, which carries parts 41 to 46, in its lowest position wherein the eccentric bearing shell is clamped by the abutment of sloping surfaces 53 (Fig. 4) on the wedging members 47, 48. To advance the punch toward the die for final sizing, pressure is relieved on side 50a of the piston 49 and applied to side 50b, thus rotating the eccentric bearing shell by direct axial movement of the worm shaft 42 until clamping of the eccentric bearing shell is caused by the abutment of sloping surfaces 54 (Fig. 3).

Title: Improvements in and relating to Gathering and Cut-off Mechanism for Glass-blowing Machines.
Inventor: WHITE ALFRED ERNEST
IPC: C03B9/24
Filed: 1916-09-12
Abstract: 109,587. White, A. E., (Westlake European Machine Co ). Sept. 12, 1916. Uathering molten metal.-Relates to automatic glass - blowing machines of the type described in Specification 26,222/11 for making electric-lamp bulbs &c., and comprises improvements in the gathering and cut-off mechanisms. T h e gathering-mould has an end-wall, preferably separable, of high heatabsorptive capacity, which is preterably higher than that of the body of the mould. Each blank mould is pivoted loosely on its gathering mechanism and consists of a body part 337, Figs. 1 and 4, preferably of copper, and a separate top 340, of copper or graphite, having a central protuberance 342. The use of the separate top keeps the top of the blank hotter than the rest of its superficial parts. The contact surfaces 335<a>, 337<a> of the support 335 and mould 337 are rounded so that the mould has a rocking bearing on the gathering-ram 322. Narrow radial slits 344 in the side of the mould communicate through ports 346 in the securing-nut 341 with the air passage 334, of the ram. The mould is completed by a hinged ring-like cover 347 which is opened and closed by a hinged telescopic rod acted upon by springs and a cam 354. The cover is pivoted on the support 335, and is operated by a spring-pressed rod 358, Fig. 3, which telescopes into a socket 359 in a member 356 hinged to a spring-pressed member 355, which is caused to slide in a guide 360 on the ram 322 by the cam 354. The lower end of the rod 358 is screwed into a casting which terminates in a fork 373 pivoted to the tongue 375 of a fork 376, the arms 377 of which have notches 378 engaging a pin 379 on the arms 349 of the cover 347. A roller 381 on the arms 377 engages the curved under portion 383 of the ram. After sucking up the molten glass, the surplus is cut off by a knife 428 moving in the direction of withdrawal of the gathering-slide, so that the severed glass falls into the furnace 325 outside the usual gathering-ring 327. The knife is actuated by a box-cam instead of by the inclined surface previously used, thereby eliminating the tendency of the sliding parts to lift and cause leakage at the registering air-ports. The knife is adjustably secured to an arm pivoted to the ram, and its cutting-edge is oblique to the direction of movement of the knife. The knife is operated by a spring-pressed rod 439 which extends into a socket 441 on a rod 440 connected to a bell-crank 446, which is mounted on the ram 322 and has a roller engaging the box-cam on the carriage 324 of the ram. Specification 111,122 also is referred to.

Patent GB-360311-A (GB)
Title: Manufacture of mixed cellulose esters derived from both nitric acid and a fatty acid
IPC: C08B7/00
Filed: 1931-02-24
Abstract: Cellulose nitrate-carboxylates are produced by reacting on a fatty acid, if desired with addition of its anhydride, in the presence of a cellulose nitrate containing at least two nitrate groups to the molecule, with a substance which transforms the fatty acid into its acid chloride.  Examples of such substances are thionyl chloride, sulphuryl chloride, phosphorus oxychloride, phosphorus trichloride or pentachloride, and phosgene.  The reaction, which is preferably carried out in the presence of a small quantity of water, proceeds with the partial elimination of the nitrate groups.  In an example, collodion cotton containing 11,1 per cent of nitrogen is dissolved in glacial acetic acid, and thionyl chloride is added.  The product is separated in flakes by pouring into water and contains 5,2 per cent of nitrogen. According to a further example in which the original structure of the fibre is retained, collodion cotton having a 20 per cent moisture content is introduced into a solution in benzene of acetic anhydride and acetic acid, to which has been added thionyl chloride and sulphuryl chloride.  The products may be converted into artificial threads, films and the like.

[Class 80 (ii)] The engine crankshaft 1 carries a flywheel 2 forming the driving member of the clutch, and an extension in the form of a stub shaft 3 for supporting the driven parts. Surrounding this stub shaft is a driven sleeve 4 free to rotate on but capable of slight axial movement relative to the stub shaft, being confined endwise between a thrust collar 5 at one end and the flywheel at the other. The sleeve 4 carries at its rear end a flange 7 for connection to a splined coupling member 8 and has, on its outer surface, a series of quick-pitched helical ribs or splines 9. The driven member 10 of the clutch is carried by a sleeve 11 having internal ribs or splines adapted to engage those on the sleeve 4. The sleeves 11, 4 have, respectively, flanges 13, 14 connected by clutch springs 15 which force the clutch members together. To disengage the clutch, the flanges are brought closer together by a pedal-operated cam 18 engaging the outer ends of levers 16, 17. The helical connection causes the clutch members to be engaged more strongly the greater the torque. Further, if the vehicle over-runs, the clutch member 10 is withdrawn at a speed depending on the strength of the springs 15.

Title: Method of and means for controlling the supply of lubricating oil to internal combustion engines
IPC: F16N27/00
Filed: 1935-02-25
Abstract: 451,363. Lubricating internalcombustion engines. CROSS, R. C., 33, Midford Road, Odd Down, Bath. Feb. 25, 1935, No. 5990. [Class 12 (iii)] [See also Group XXIX] In means for supplying lubricant to internalcombustion engines in quantities proportional to the throttle opening, a valve member 10 is slidably carried in a rod 7 and is urged by a spring 11 towards a seating formed by the conical bore of a casing 1. The rod 7 passes through a stuffing-box at one end of the casing 1 the other end of the latter being connected to an oil supply pipe 3 delivering oil to a pipe 4 leading to the engine. Some of the oil supplied by the pipe 3 byepasses the valve 10 and is led by a pipe 16 back to the oil sump. The outer end of the rod 7 is pivoted to a lever connected to a part of the engine which moves in accordance with the throttle opening. When the throttle is widely open the parts take up the position shown in full lines, the spring 11 being compressed so that only a little of the oil is byepassed. As the throttle closes the parts move towards the dotted line position so that more of the lubricant is byepassed. The byepass pipe 16 may be formed to offer considerable frictional resistance to the oil when the latter is cold and viscous, or manual means may be provided to keep the oil pressure at the correct value until the engine has warmed up. The invention may be applied to the lubrication of the rotary valves such as those fitted with oil scrapers as described in Specification 423,474.
