Abstract: 381,329. Endless belt conveyers. MAYOR & COULSON, Ltd. and THOMSON, J., 47, Broad Street, Mile End, Glasgow. Oct. 5, 1931, No. 27632. [Class 78 (i).] In a conveyer of the kind in which the lower run is protected by inverted troughing, inverted trough sections are employed which overlap at the joints of the section, the overlapping ends being interlocked with a supporting frame by longitudinal movement to resist vertical displacement and being held against longitudinal displacement by separate locking means. The end 5a of the section 5 is overlapped by the section 6 when the sections are properly positioned, and the sections are held together by a pin inserted through apertures in brackets 21, 23. The troughing is supported at the joint by a frame comprising side angle-members 7 and cross members 8. Slots 9 in the ends of the members 7 receive the inturned ends 10 of iron bands 11 fixed round the inside of the sections and prevent vertical displacement. Vertical slots 12 in the members 7 receive the spindles 13 of the idler rollers 4 which are retained in position by looking plates 14. A feeding hopper travels upon rails supported from the inverted troughing. The rails are fewer in number than the sections of troughing, and are shifted from one position to another when it is desired to alter the position of the hopper. Specifications 285,627 and 299,218, [both in Class 78 (i), Conveyers &c.], are referred to.

Patent GB-607885-A (GB)
Title: Improvements relating to synthetic resinous moulding compositions
IPC: C08J5/04
Filed: 1945-10-23
Abstract: A moulding composition includes unspun staple fibres of regenerated cellulose of tenacity at least 3 grams per denier of average length at least 0.75 inch, impregnated with synthetic resin.  The fibres may be impregnated with resin solution, e.g. with pressure following application of vacuum, and the solvent then removed, first at ordinary and then at higher temperature. The fibres are separated while they contain residual solvent. Hardening agents, catalysts, mould lubricants, colouring matters may be included in the impregnating solution.  The high tenacity material may be obtained by stretching in wet steam or hot water, p  yarn, dry spun from cellulose acetate, preferably of high molecular weight, saponifying it and cutting to staple fibre or by stretching and cutting yarns obtained by the viscose or cuprammonous process.  Yarn waste may be cut to yield the fibre. Other fillers, e.g. wood flour or asbestos, may be used with the fibre.  Suitable resins are condensation products of phenol with acetaldehyde, formaldehyde, benzaldehyde or furfural, or of these aldehydes with meta-cresol, resorcinol, urea, thiourea, guanidine, dicyandiamide, piperazine or melamine, or polymers of diallyl phthalate, diallyl ketone or allyl methacrylate. In an example, a resin prepared by condensing equimolecular proportions of phenol and acetaldehyde in the presence of an acid catalyst is dissolved with hexamethylene tetramine and aluminium stearate in industrial alcohol.  The staple fibre is fed on to the perforated false bottom of a pressure vessel which is evacuated and the synthetic resin solution is then introduced and pressure is applied by admitting air, which bubbling through the perforations in the false bottom acts to stir the mass.  The impregnated fibre is removed, centrifuged and dried slowly to an alcohol content of 5 per cent.  Adhesion between the fibres is then broken down, e.g. in a rotating arm disintegrator, shortening of the fibres being avoided. Standard bars are moulded from compositions with varying proportions of resin and fibre and tested for impact strength.

Abstract: 785,771. Fluid-pressure servo motor-control systems. SVENSKA TURBINFABRIKS AKTIEBOLGET LJUNGSTROM. Oct. 3, 1955, No. 28129/55. Class 135. A device for regulating the speed of turbines and other engines comprises an inner slidable valve member 1 actuated by a. centrifugal governor driven by the engine and a surrounding outer slidable member 2 operated by a servomotor through restoring mechanism, the two members 1, 2 constituting a valve mechanism for controlling the servomotor which in turn operates the inlet valve of the engine. According to the invention, the inner member 1 is formed with three valve closure surfaces co-operating with three seating surfaces on the outer member 2, one of the closure surfaces being opened on a reduction of speed to admit liquid to the servomotor so as to open the engine inlet valve further, and the other two closure surfaces being opened on an increase of engine speed to allow liquid to be discharged rapidly from the servomotor. Thus overspeed variations are checked more rapidly than underspeed variations. The slidable members 1, 2 are mounted in a housing 5 having a connection 5<1> to an oil pump and a connection 52 to the servomotor. The inner member 1 is connected by a rod 3 to the centrifugal governor and the outer member 2 by an arm 4 to the restoring mechanism. On a decrease of speed, the inner member 1 rises and oil is admitted to the servomotor through the gap formed at 11. On a decrease of speed, the inner member 1 descends and oil from the servomotor escapes past gaps formed at 12, 13 and through ports 9, 10 to an oil tank (not shown).
