Title: Improvements in or relating to coin freed or coin actuated delivery machines
IPC: G07F11/24
Filed: 1936-03-20
Abstract: 472,403. Coin - freed article delivery apparatus. MARCHANT, E. G., and MARCHANT, L. March 20, 1936, Nos. 8406 and 14988. [Class 27] Coin action, weight.-Articles are delivered in succession from a circular series of vertical magazines 2, Fig. 1, by a rotary ejecting device comprising a series of radial arms 7 with upturned ends 8 projecting radially from a central vertical shaft 6, the arms and magazines being so spaced that at predetermined intervals two or more articles are ejected. The shaft 6 is rotated step-wise, after prepayment, by a hand knob 13 on a'shaft 11 having a bevel wheel 10 meshing with a bevel wheel 9 on the shaft 6, which also carries a star wheel 20 normally engaged by a locking pawl 19 carried by an horizontal shaft 17. A coin, dropping down a shoot 15, hits an arm 16 on the shaft 17 to rotate this and disengage the pawl 19. A latch 21 on the shaft 17 is also brought, by this rotation, into the path of the teeth of the star wheel. When the shaft 6 is rotated to eject an article, the latch 21 is engaged by the star wheel and moved to restore the shaft 17 to its initial position. In a modification, Fig. 4, the ejector mechanism 23 is carried by a vertical shaft 24 having a screw-thread of steep pitch and rotated by a dropping weight 25 having a lug 26 engaging a vertical guide-way. The ejector arms project radially from a disc 23 having upstanding teeth 31 angularly disposed with respect to the periphery of the disc. The disc 23 is normally locked by a pivoted latch 30 engaging the innermost edge of one of the teeth. When the latch is tilted by a coin dropping thereon, the disc 23 is rotated through the space of one tooth, the inclined tooth passing through a slot 34 in the latch 30 to return this to its initial position so that it engages the next tooth on the disc. Backward rotation of the shaft 24 is prevented by a pawl engaging a ratchet wheel 29.

Abstract: 416,864. Stapling continuous filaments by drawing. BRITISH CELANESE, Ltd., 22, Hanover Square, London, HALE, F. C., and TYCE, G. C., c/o British Celanese, Ltd., Spondon, near Derby. March 23, 1933, No. 8765. [Classes 120 (ii) and 120 (iii).] Staple fibres are obtained from continuous filaments by subjecting a bundle of filaments to a breaking tension and confining the filaments along that part of their length over which such tension is applied within a space which is restricted laterally of the filaments. The staple fibres may be wound up and twisted continuously with production. The continuous filaments may be of regenerated cellulose made from viscose or cuprammonium solution, or of cellulose acetate or other organic cellulose derivative. As shown in Figs. 1 and 3, continuous filaments 5 pass between a pair of breaking rollers 6, 7 and then between a further pair of rollers 8, 9 to a cap spinning device 10. Rollers 8, 9 rotate faster than rollers 6, 7 and stretch the filaments beyond the breaking point. A tube 14 surrounds the filaments whilst they are being broken and supports them between the two pairs of rollers. To minimize wear on the rollers, the tube 14 is reciprocated by cam or other means. The tube 14 and clamp 16 are slotted to facilitate threading of the filaments. Pressure between the breaking rollers is maintained by a bridgepiece 20 which rides on the axles of the top rollers, and the pressure is regulated by a bolt 23 and nut 24 which may be placed at any of the apertures 25, 26, 27. The rollers may accommodate several filament bundles. The tube 14 may be of steel, brass, glass, or porcelain. If made of metal it may be earthed to disperse electric charges. Specification 410,805 is referred to.

Title: Phenolic methylol-phosphorus polymers
Inventor: REEVES WILSON ALVIN
IPC: C08G8/00
Filed: 1955-03-30
Abstract: The invention comprises phosphorus-containing polymers represented at least in part by the formula <FORM:0775325/IV(a)/1> or <FORM:0775325/IV(a)/2> where R is hydrogen, halogen or a hydroxyl or hydrocarbon radical or a radical of the formula <FORM:0775325/IV(a)/3> A is an anion, and m is an integer of at least 2.  They are prepared by reacting a phenolic conpound with a tetrakis (hydroxymethyl) phosphonium salt, e.g. the chloride (THPC), tris-(hydroxymethyl) phosphine oxide (THPO), or a phosphorus-linked methylol-group-containing derivative thereof. The product may be further reacted with a phosphorus-linked methylolgroup-containing derivative, e.g. the reaction product of THPC and urea.  Suitable phenolic compounds are phenol, resorcinol, catechol, hydroquinone, phloroglucinol, p - tert. - amylphenol, vinyl and allyl phenols, o-bromophenol, bromohydroquinone and 2,4-dibromo-1-naphthol.  The initial phosphorus-containing reactants may comprise a mixture of THPC and THPO, and their methylol derivatives include the reaction products with nitrogen compounds such as melamine, methylolamine, acrylamide, diacetamide, lysine, diethanolamine, cetylamine, ethyleneimine, ammonia and hydrazine, or with esterifying agents such as acetic, phthalic and chlorenolic anhydrides, oleyl chloride, and stearic, pinic and sebacic acids.  The reaction may be effected in the presence of a solvent such as water, water-soluble aliphatic alcohols, glycols, acetone and dioxan. Catalysts may be used, those which are used for phenol-aldehyde condensations being suitable. Temperatures of about 70 DEG  to 170 DEG  C. are generally employed. Where either or both of the reactants contain olefinic unsaturation, the products produced retain the unsaturation and may be halogenated, alkylated or polymerized by means of vinyl-type catalysts.  Modified phenol-aldehyde resins are produced by replacing a part of the THP compound with an aldehyde.  The condensations pass through three distinct stages comparable to the A, B and C stages of phenol-aldehyde condensation.  The polymers vary from viscous, soluble liquids to insoluble solids and are resistant to burning. Specifications 740,269, 764,313 and 764,314 are referred to.
