Title: Improvements in the manufacture and production of synthetic resins
IPC: C08G12/26
Filed: 1937-06-07
Abstract: Resins, for use as shellac substitutes, e.g. in polishes, paper sizes, or (especially with mica added) insulating-material, and sound records, are prepared by condensing aliphatic aldehydes containing at least two carbon atoms by means of primary or secondary aliphatic or cyclo-aliphatic amines or secondary heterocyclic bases or their salts, in the presence of surface-tension-reducing agents, which may be added before or during condensation, e.g. after the primary condensation but before heat-hardening.  The surface-tension-reducing agents may be those having a lipoid radical, e.g. an aliphatic carbon chain of at least 10 atoms, and one or more hydrophilic groups. There are specified: aldehydes-acetaldehyde, aldol, crotonaldehyde; catalysts-methyl-, ethyl-, butyl-, cyclohexyl-, dimethyl-, diethyl-, dicyclohexyl-amine, piperidine, or their salts, e.g. lactates or acetates; surface-tension-reducing agents-alkali salts of fatty acids having at least 10 carbon atoms; ammonium bases having at least 10 carbon atoms, e.g. trimethyl-dodecyl ammonium hydroxide; salts of amines containing at least 10 carbon atoms, e.g. dodecylamine hydrochloride; condensation products of hydroxy- or amino-alkyl sulphonic acids with fatty acids containing at least 10 carbon atoms, e.g. of taurine or hydroxyethanesulphonic acid with lauric or stearic acid; polyalkoxy-compounds of alcohols, amines, acids, or mercaptans having at least 10 carbon atoms, e.g. polyethoxy-compounds of sperm oil or dodecyl alcohols; true sulphonic acids or sulphates of aliphatic alcohols containing at least 10 carbon atoms, e.g. lauryl or octodecyl alcohol; alkylated naphthalene-sulphonic acids; and condensation products of naphthalene-sulphonic acids with aldehydes. There may also be present during condensation other substances known to be favourable, e.g. polyhydric alcohols, resin acids, or substances having mobile hydrogen atoms, such as aceto-acetic ester or malonic ester.  The products may be after-treated, e.g. with formic acid, condensing halides, formaldehyde or its equivalent, or a plurality of these.  In examples: (1) acetaldehyde is condensed in the presence of diethylamine, then with a condensate of sperm oil alcohol and ethylene oxide, and after-treated with formic acid followed by formaldehyde; (2) crude aldol is condensed in the presence of diethylamine, then with a condensate of dodecyl alcohol and ethylene oxide; (3) crotonaldehyde is condensed in the presence of diethylamine lactate and octodecyl sulphate and after-treated with formic acid and formaldehyde.  Specifications 470,280 and 474,034 are referred to.  The Provisional Specification refers also to Specification 478,370.  Polyalkoxy-compounds of alcohols, amines, acids, or mercaptans are formed by treating the substances in question with alkylene oxides, e.g. sperm oil alcohols are treated with 20, or dodecyl alcohol with 8, mols of ethylene oxide.

Title: Dispensing Device
Inventor: MOLE WALTER ERNEST
IPC: B67D1/04
Filed: 1967-04-11
Abstract: 1, 171, 698. Dispensing liquids by gaseous pressure. DISTILLERS CO. (CARBON DIOXIDE) Ltd. April 11, 1968 (April 11, 1967], No.16511/67. Heading F1R. A dispenser of liquids from a container comprises a body provided with means for attaching the dispenser to the container, a sharp tube capable of piercing a hole in the lid of the container, a seal on the underside of the body surrounding the tube which when the dispenser is attached to the container forms a substantially gas-tight chamber around the tube, the chamber being in communication with the interior of the container via the hole in the lid, a supply of carbon dioxide under pressure with which the chamber is in communication via a non-return valve, and a delivery tube housed within the sharp tube which communicates with a dispensing tube projecting from the body of the device. After removal of a dip tube 8, a sharp tube 1 is forced into the lid of a beer can to form a hole. The dip tube 8 is then refitted and a screw thread 3 is screwed into the hole in the lid until a seal 43, which may be of silicone rubber, is in sealing engagement with the lid. A capsule 21 of high-pressure carbon dioxide is placed in a holder 20 and a cap 22 is screwed on, a pin 23 on the cap piercing the capsule. High-pressure carbon dioxide passes through a pressure reducing valve, a sintered metal filter 34, and a capillary tube 29 to a low-pressure chamber 25. The pressure reducing valve is formed by the engagement of the end of the capillary tube 29 with a polyurethane pad 30, the capillary tube being pressed against the pad by a piston 26 subjected to the pressure in the low-pressure chamber 25 and the opposing force of a spring 27. From the low-pressure chamber 25, the low-pressure carbon dioxide passes via a duct 39, a duct (38) and a non-return valve (44) into the space between the seal 43 and the sharp tube 1 and thence into the beer can. On depression of a button 5 to the position shown, a bore 11 is brought adjacent a port 12 to allow beer, urged by the carbon dioxide to be delivered via the dip tube 8, bores 10, 11, port 12 and a dispensing tube 13. A relief valve (45) vents excessive pressure to atmosphere. Castellations 55 cooperate with pins (56) depending from the button 5 so that by rotating the button the dispenser can be locked into a non-dispensing state. Instead of a screw thread 3, spring members hooking over the rim of the can may be used. Alternatively, a bayonet-type joint may be used with cans provided with the necessary fitment. The pin 23 can be provided at the other end of the holder 20, projecting from the pad 30. Provision may be made for holding two carbon dioxide capsules with interchangeable connections to the interior of the can. The carbon dioxide supply may be a large cylinder of liquid carbon dioxide under pressure.

Title: Process and mechanism for the manufacture of eccentrically or segmentally grooved rollers for rolling mills
IPC: B23Q35/10
Filed: 1921-06-16
Abstract: 169,955. Becker, H. Oct. 6, 1920, [Convention date]. Lathes. - In a lathe for shaping the grooves of pilger rolls &c., a tool, having a cam-controlled movement towards the work axis to impart the required eccentricity to the roll section, receives in addition a curvilinear motion corresponding to the desired groove profile. The tool 6 is carried on a compound slide 4, 5 mounted on a member 3 pivotally supported by the cross slide 2. The slide 4 carries a stud 8 spring-pressed against a cam 10 driven by bevel-gearing from a hollow shaft 13 carrying one wheel of a differential gear 14, the wheel 35 of which is driven through spur and bevel gearing from the feed shaft 38. A shaft 20 driven by spur gears 22, 23 from the cross-feed spindle 21 carries a worm 24 engaging a worm wheel 25 on the pivoted member 3. The eccentric roll section indicated in Fig. 3 is derived from the rotation of the cam 10, while simultaneously a curvilinear motion is imparted to the tool to shape the groove by the worm gearing 24, 25. In order to compensate for the rotation of the slide carrying the stud 8 in contact with the cam, the motion of the cam-driving shaft 13 is modified by means of a worm 16 driven by bevel-gearing 18, 19 from the shaft 20 and engaging a worm-wheel on the differential casing 15. When the curved portions of the roll profile have been completed, the wheel 23 is declutched from the shaft 20, which is then connected through spur gears 27 with a toothed sector 30 oscillated by a cam 33. The latter is arranged to rotate once for each revolution of the work, and the resulting oscillation of the sector is transmitted to the shaft 20 to vary the inclination of the roll flanks at different points round the section, as indicated in Fig. 9. For facing the sides of the roll flanks, the spindle 7 is ratchet driven to feed the top slide 5 'in the required oblique direction. The lathe is also applicable to any ordinary turning work.
