Title: Process for the esterification of fatty acids with low-molecular univalent alcohols
IPC: C11C3/00
Filed: 1947-01-16
Abstract: Fatty acids are esterified with low molecular univalent alcohols containing up to 6 carbon atoms using a mononuclear or polynuclear aromatic sulphonic acid readily soluble in water and in the fatty acid and alcohol used as a catalyst, the reaction being carried out at temperatures above the boiling point of the alcohol but below the boiling point of the ester to be manufactured.  The catalyst may have one or more sulphonic groups and may be substituted by halogen or by alkyl, aryl, amino, hydroxy or carboxy groups.  Specified catalysts are b -camphorsulphonic acid, benzene sulphonic acid, diphenyldisulphonic-4 : 41-acid, a - and b -naphthalene sulphonic acid, b -naphthalenedisulphonic acid, a -chloronaphthalenesulphonic acid, naphthol - 1 - sulphonic - 4 - acid, sulphosalicylic acid and a -naphthol-e -disulphonic acid. The reaction may be carried out with a very small proportion of catalyst, e.g. 0.1-5 per cent and a counter-current process may be used if desired.  In examples, rape seed oil fatty acids, or peanut oil fatty acids are esterified with ethyl alcohol using as a catalyst one of b -camphor sulphonic acid, a - or b -naphthalene sulphonic acid, benzene sulphonic acid, sulphosalicylic acid, naphthalene disulphonic acid, a -chloronaphthalenesulphonic acid, naphthol - 1 - sulphonic - 4 acid or a  - naphthol-e -sulphonic acid.  In place of ethyl alcohol methyl, n-propyl, isopropyl, butyl or isobutyl alcohol may be used. Specification 545,415 is referred to.

Abstract: 810,159. Sealing packages. HERMORION Ltd. Jan. 17, 1957 [Jan. 25, 1956], No. No. 1759/57. Class 94(1). A jaw 1, which co-operates with an opposed heated jaw to form spaced transverse seals in a tube of wrapping material fed between the jaws, comprises a plate 3 formed with a dovetail groove 7 for the reception of an elastic, e.g. rubber, pad 4 of similar shape forming the operative face of the jaw. The ends of the groove are closed by shoulders 6. If the tube is formed with a longitudinal seam, the part of the pad which engages the seam and the corresponding part of the groove are formed with bevelled edges 10, 11. Local variations in the elasticity of the pad may be produced by varying its longitudinal or transverse cross-section or the cross-section of the space defined by the groove and shoulders. If the tube encloses a liquid which is displaced by the jaws from the areas to be sealed, the bottom of the groove may be formed with a longitudinal ridge so that the pressure exerted by the central portion of the pad is initially greater than that exerted by its longitudinal edge portions.

Abstract: 124,543. Armstrong, Whitworth, & Co., Sir W. G., and Le Mare, A. H. Feb. 1, 1918. Naval mountings; mounts, self-adjusting for keeping plane of sights vertical; mounting, dismounting, and housing; recoil apparatus.-Relates to self-levelling mountings of the kind, described in Specification 127,899, in which the gun is mounted on a gimbal frame carried on a rotary ring on a cup-shaped base, and is maintained in the vertical plane and at the correct angle of elevation by a spring. The invention consists in (a) means for adjusting the operative length and tension of the spring, (b) special bearings between the rotary ring and the cup-shaped base, and (c) a special construction of the elastic cushion on which the cup-shaped base is supported. In the construction shown in Fig. 1, the helical spring a is wound at one end on a cylindrical block b so that the length and tension of the spring is adjusted by varying the number of coils wound on the block. In the construction shown in Fig. 3, the helical spring a acts on a lever j bearing against a fulcrum l carried by a slide m which moves in a path inclined to the lever, so that, by adjusting the slide by means of the screw o, the position of the fulcrum l and the tension of the spring are adjusted. The bearings between the rotary ring and the cup-shaped base p consist of balls u, Figs. 7 and 8, or conical rollers t, Figs. 4 and 5, for taking the axial thrust, and cylindrical rollers v, Figs. 4, 6, and 8, having surfaces of two diameters for the transverse pressures.

Volatile components, such as monomer or solvents, are removed by vaporization from a molten polymer by feeding it through annular ring 3 into a barrel I wherein the polymer is distributed as a moving film on the inner surface iby a rotating, hollow worm-screw 2 having a helical flight 4 with a clearance of 0.5 to 2.8 m.m. from the inner surface of the barrel. The screw has slots (not shown) through which the vapours pass into the hollow core, which is connected to a source of vacuum. The screw is rotated at high speed so that the polymer is subjected to a rate of shear 'between 500 and 2000 reciprocal seconds. The devolatilized polymer is forced through pumping section C to exit 6. The barrel may be surrounded by a heating or a cooling jacket. The worm screw may have a plurality of flights. Short strips having varying clearances may be mounted on the screw parallel to the flights.

Abstract: 556,148. Shock-absorbers. RIBBESFORD CO., Ltd., and THORNHILL, P. W. Feb. 20, 1942, No. 2306. [Class 108 (iii)] An oleo-pneumatic shock absorber in which provision is made for one of the telescoping members to rock laterally with respect to the other as described in Specification 554,983, comprises a cylinder 10, a hollow piston rod 16 with a barrel shaped piston 25 having a central aperture, and forming an oil space 51 in the cylinder an upstanding fixed hollow standard 31 in the oil space with a recoil head 36 operating in the hollow piston, and a floating piston 46 in the hollow piston rod maintained by air pressure supplied through an opening 55 in the hollow piston rod. The axle 23 supporting the wheel is carried by a lever 22 pivoted at 24 to which point is fixed an arm 15 terminating in a sleeve 14 in which the lower portion of the cylinder 10 is supported, the upper end of the cylinder being attached to the vehicle carrying the wheel. The wheel end of the lever 22 is connected by an universal joint 19, 20 to the lower end of the hollow piston rod, which passes through a resilient end closure 28, 29 for the cylinder and sleeve. The upper end of the hollow standard is also resiliently connected at 32 to the upper end of the cylinder and a valve 38 capable of lateral movement with respect to the central aperture 37 in the hollow piston 25 surrounds the standard at this position. On impact of the wheel with an obstruction, the hollow piston rod is forced upwardly into the cylinder and displaces liquid from the space 31, partly into the space 48 in the piston rod through the valve 38 and partly into the space 49 between the head of the standard and the floating piston 46 through the standard by way of apertures 52 therein. This movement raises the pressure of the air in the space 50 so that recoil sets in, but the liquid trapped in the space 48 can only escape at a slow rate between the valve 38 and the standard and so the movement of recoil is damped. During this movement liquid flows from the space 49 to the cylinder 51 through the standard to keep this space full.

In the driving position shown, the worm bears against a collar 9 connected to the shaft by a breakable pin. On the engine starting backwards, this pin is broken and the worm is moved to the right out of gear. In a modification, the worm 4 is fixed on a slidable shaft, a spring stop being provided for holding the shaft in either end position with the worm out of gear; the starting handle is mounted in a bracket over the starting motor. and both drive the worm shaft through toothed gearing. In a further Form, the abutment stop for the worm is acted on by a strong spring, which yields in case of backward rotation of the engine.
