Title: Variable speed gearing
IPC: F16H61/02
Filed: 1929-08-28
Abstract: 332,789. Soc. d'Exploitation des Brevets Cotal. Feb. 9, 1929, [Convention date]. Variable - speed epicyclic gearing comprises a simple train 3, 7, 8, Fig. 2, of which the planets 7 are carried by a driving-shaft 1, the annulus 3 is fast on the driven shaft 2, and the sun 8 may be clutched solid by an electromagnetic clutch or held fast by a like brake. Magnetic action in the clutch &c. may be replaced at will by the use of keys, and the current may be automatically disconnected when the engine is stopped. Thus armature 9 fast to sun 8 may. be attracted to magnet 4 on annulus 3 for solid driving, or, alternatively, attracted to fixed magnet 10 for yielding an over-drive. The amount of air-gap in the magnets is controlled and adjusted by screws 13 which pass through sockets 12, which in turn screw into the gear-case 11. In an arrangement shown in Fig. 3, this over-driving train 3, 7, 8 may be combined with another train using the same annulus 3 and yielding a speed reduction. When clutch armatures 9, 9a are both attracted outwards, both trains are locked solid and a solid drive results. When armature 9 alone is attracted inwards, train 8, 7, 10 operates, yielding an over-drive. When armature 9<a> alone is attracted inwards, train 10, 7<a>, 8a operates, yielding a reduced drive. When both armatures are attracted inwards, the trains work against one another, yielding a fourth speed. To supersede the magnetic action, keys 14, Figs. 4 and 5, are fitted to slide in the outer edges of the armatures 9. These keys are operated in unison by a striker-ring 1 controlled by an eccentric pin 17 in a hand-operated disc 17<a>. The keys 14 can be engaged with notches 15, 15<1> in the magnets 4, 10 respectively, and the keys 14 are provided each with three notches 21 engaged by a locking spring ball 18. A switch for breaking current when engine shaft 1 stops is shown in Fig. 7. A centrifugal weight 28 slides on a conducting-rod 31, which connects at 32 to the clutch coil. In its outmost position the weight 28 contacts at 25<1> with the end of a conducting strip 25, which extends from a brush contact 23. As shaft 1 slows down, weight 28 is thrust inwards by spring 30 and moves over rheostat wire 26, so that the current weakens, the clutch slips, and the driven shaft moves more slowly. At the inmost position of weight 28 the circuit is broken.

Patent GB-869828-A (GB)
Title: Method of preparing vinyl esters of carboxylic acids
IPC: C07C69/01
Filed: 1957-08-21
Abstract: Vinyl esters are produced by reacting a carboxylic acid and a vinyl ester reactant in the presence of a mercury-acid salt vinyl inter-change catalyst, neutralizing the co-catalyst acid with a neutralizing agent comprising an alkaline earth metal base which is insoluble in the reaction product mixture to form an insoluble salt of the catalyst acid, removing the resulting insoluble material from said reaction product mixture, separating the vinyl ester product and mercury-containing residue and repeating said reaction using the mercury-containing residue with a corresponding amount of strong acid catalyst.  The neutralization and removal of insoluble material may be effected at about 60 DEG C., filtration being aided by adding a finely divided diatomaceous earth. Low-boiling constituents may then be removed by distillation, and the vinyl ester product separated, e.g. by distillation or by extraction, for example as described in Specification 869,830. The carboxylic acid may be an aliphatic monocarboxylic acid, aliphatic dicarboxylic acid, half ester of an aliphatic or aromatic dicarboxylic acid, an alicyclic acid or aromatic acid. Vinyl acetate is the preferred ester but vinyl esters up to the heptanoate are specified.  Mercury salt-strong acid catalysts are most effective including mercuric oxide or acelate with sulphuric, phosphoric, p-toluene sulphonic or trifluoroacetic acid. During the reaction, the vinyl ester reactant by-product acid may be continuously removed as described in Specification 869,829. Examples describe the preparation of vinyl stoarate, divinyl sebacate, vinyl benzoate, methyl vinyl succinate, vinyl cyclohexane carboxylate, and methyl vinyl phthalate.

Abstract: 963,832. Welding or cutting by fusion. AIR REDUCTION CO. Inc. July 29, 1960 [Aug. 24, 1959], No. 26579/60. Headings B3R and B3V. [Also in Division H1] In electron beam welding or cutting apparatus, the electron beam of high current intensity, e.g. 1 ampere, and low voltage, i.e. below the X-ray hazard limit, is focused to a cross-over 46, Fig. 3, in the plane of the anode aperture, allowed to expand to a large diameter under its own space charge and then converged to a small spot by the magnet coil 35. The angle of convergence 60 is equal to about 28 degrees and is stated to be critical if both beam spread and chromatic and spherical aberrational defects are to be avoided. The angle of convergence may be determined by measuring the maximum beam diameter. This is determined by supporting an aluminium sheet coated with a phosphor and marked with a scale in the path of the beam. The housing, Fig. 1, comprises a main conduit 1a with a hinged door 4 at one end and a coupling flange 5 for connection to a vacuum pump at the other, and a branch conduit 1b containing the electron gun structure 19 which is mounted on a cylindrical support 14 telescopically adjustable within the branch conduit. The workpiece 8 is mounted on a rotatable shaft 9 opposite the electron gun and provision may also be made for translating the workpiece sideways. The electron gun structure, Fig. 3, comprises a demountable assembly of stacked insulating cylinders 12, 22 and metal cylinder 20 and includes a cathode filament 32, shown in Fig. 5, mounted on rods 37, 38, passing through seals in the end plate 30, a control electrode 33 supported from the endplate 30 by bolts 45 and an axially adjustable anode 34 threadably mounted in the aperture 34a of plate 26.
