Title: Improvements in and relating to the manufacture of varnishes
IPC: C09D167/08
Filed: 1932-09-02
Abstract: In the manufacture of varnishes, a varnish resin is incorporated, at raised temperature and in the absence of solvent, into an alkyd-resinous oil containing the radicals of a polyhydric alcohol, a drying oil and a polybasic acid, and having an oil length which is not less than 50 per cent.  A varnish is then formed by the addition of suitable solvents or thinners.  A suitable alkyd-resinous oil may be prepared from phthalic anhydride, glycerol, linseed oil fatty acids, and linseed oil, while resins which may be incorporated include French resin, Congo copal, colophony, or materials known under the Registered Trade Marks of "Albertol" and "Bakelite."

Filed: 1922-09-18
Abstract: 203,527. Gast, C. Sept. 18, 1922. Machine guns.-A breech-bolt locking mechanism for automatic guns of the recoiling-barrel type comprises two laterally disposed circular locking- discs 16 which are rotatable within the barrelextension 3 by the engagement of striking faces 16<d>, 16<c> on the discs with fixed abutments 15b, 15<a> during the recoil and return movements of the barrel. Diametral slots 16<a> in the discs register with lugs 6<a> on the breech-bolt 6 when the discs are rotated for unlocking by the engagement of the faces 16d, 15b during the initial recoil of the barrel. The opening and closing loading movements of the breech-bolt are thus permitted, and the final return of the barrel causes the engage-- ment of the faces 16<c>, 15<a> to rotate the discs behind the lugs 6a and thereby lock the breech-bolt.

Abstract: 858,611. Turbine and compressor blades. ROTAX Ltd. July 29, 1959 [Aug. 7, 1958], No. 25327/58. Class 110 (3). A hollow blade for a turbine or blower is made from a sheet or sheets of fibrous material impregnated or coated with a synthetic resin, or from a sheet or sheets of hard synthetic plastic material, and has incorporated with one of its ends a metal reinforcement d from which extends a stub pin e. To form the blade, the reinforcement member d is assembled together with a member c of synthetic plastic material which is formed with perforations and serves to reinforce the outer end of the blade, a pair of thin metal or other strips b each shaped to channel cross-section and placed back-to-back to serve as central longitudinal reinforcement in the blade, and with fusible core pieces a which are shaped so as to correspond with the desired inner profile of the completed blade. A sheet or sheets of fibrous material f, preferably made from glass fibres or woven cotton or other fabric, 'impregnated or coated with a synthetic resinous material is then wound on to, or applied to each surface of, the assembly, and the whole is then placed in a mould consisting of a base and a cover. The parts are then subjected to pressure and are bonded together by heating or by means of an adhesive substance. After removal from the mould, the blade is heated so as to cause the core pieces a to melt and the molten material is removed through the perforations in the reinforcement member c. A sheet or sheets of hard synthetic plastic material such as polyvinyl or polythene may be used in place of the impregnated or coated fibrous material. The blade is particularly suitable for air-driven turbines.

Stop-motions.-In jigger dyeing-machines &c. in which the hands of the operative are liable to be wound beneath the coils of fabric, bars 20 on arms 21 are mounted on shafts 23 on each side of the vat, so that in the event of the operative being dragged towards the vat, his body comes into contact with one of the bars which is thereby turned and effects a stoppage of the machine. Each shaft 23 carries an arm 24 connected bv a chain 24a with a steam valve 26. When a bar is operated, the valve is opened, and a piston 29 in a cylinder 28 moves the driving-belt 10 from the fast pulley 7 to the loose pulley 8 through a connecting-rod 30, lever 31, sliding-bar 32, lever 12, and belt-fork 11.

A rack 15 is mounted on the bar 13, so that the machine may also be stopped by hand-wheels 17 carrying a pinion 16 in engagement with the rack. Means are provided for applying a brake simultaneously with the shifting of the belt on to the loose pulley. Instead of fast and loose pulleys, a driving- clutch may be employed. According to the Provisional Specification, the detector bar may operata devices for disengaging the clutch of the driving or winding-roller of the jigger.
