Title: Improvements in and relating to coin-freed vending machines
IPC: G07F5/02
Filed: 1939-06-29
Abstract: 530,739. Fraud, preventing ; coin-action, thrust. HALL TELEPHONE ACCESSORIES (1928), Ltd., and HALL, F. W. June 29, 1939, No. 18994. [Class 27] A coin-freed vending machine has mechanism which prevents fraudulent operation, the means for delivering the articles being nor. mally locked. A hopper 1 adapted to receive two coins x, x<SP>1</SP> i: mounted loosely on a shaft 4 and can be rocked manually to a position in which the coins are discharged The hopper 1 is carriec by a lever 3 which may be operated by an ex ternal knob and has a pawl 8 which engage! a ratchet wheel 7 fixed to the shaft 4. P ratchet wheel 9 fixed on the shaft 4 is normally locked by a detent 10a on an arm 10 pivoted a 14a, and spring biassed into the locking position. The arm 10 is adapted to be moved away from the locking position by the abutment of the outer coin x<SP>1</SP> against a pin 11 on the arm, when the hopper 1 is swung, thus permitting turning of the shaft 4 and delivery of the article. A friction spring-loaded eccentric 26 bears on a flange on the wheel 9 to prevent reverse movement of the shaft 4. Fraudulent operation, as by insertion of an instrument to turn the shaft 4, is prevented by a latch bar 12 a tooth 12a on which engages the wheel 9 but is normally held away therefrom by a pin 13 on the arm 10, the latch bar 12 being pivoted to the framework and pressed downward by a spring. A pawl 14 spring-pressed upward and pivoted at 14a bears against a ratchet 15 on the hopper lever 3 to prevent restoration of the mechanism to normal position before the coins have been discharged. The lever 3 may have a projection 20 which engages a projection 21 on the arm 10 to compel the latter to complete its outer movement to disengage the wheel 9, the arm 10 then swinging back with its projection 21 passing over that on the hopper. This allows of an undersized coin x<SP>1</SP> functioning although it drops prematurely.

Abstract: 130,028. Thompson, W. B. Dec. 24, 1917. Riveting.-The invention is stated to be an improvement on that .described in Specification 24208/10. The holder-up pillar 8, which is to be inserted through a hole in the boiler, is made adjustable along the base 1, which carries the riveting-head. The adjustment is effected either by bolting the sole-plate 7 of the pillar 8 in longitudinally slotted holes 5, of which a number are provided in the crown-plate of the base 1, or by means of a longitudinally-arranged rotatable threaded shaft engaging a nut on the sole-plate 7. The holder-up arm is divided longitudinally, as shown at 10, to facilitate its insertion through the hole in the boiler, and is secured to the pillar 8, after the halves are bolted together, by a key 9. The arm is also built up of sections 11 - - 14 held together by set-screws, any one of the sections being removable to adjust the tup 15 to a required position. The pillar 8 is bored out at 16 and has an inlet 17 to let in a pneumatic tube for a hand-caulker.

Exemplified bis-cyclopentadienyl-titanium compounds are bis-cyclopentadienyl-titanium dichloride, bis-cyclopentadienyl-dimethyl-titanium, and bis-cyclopentadienyl-methyl-titanium chloride.  The preferred organo-metallic compounds are of the type R3Al, R2 Al Cl, and R Al Cl2 where R is an alkyl group of 1 to 8 carbon atoms.  Exemplified organometallic compounds are dimethyl and dimethylaluminium chloride. The inert diluent may be pentane, hexane, benzene, toluene, ethyl-benzene, xylenes tetrahydronaphthalene, chlorobenzene, chloronaphthalene, methylene chloride, butyl chloride, and dichlorethane.  A small proportion of oxygen may also be added to the polymerization system.  The polyethylene may be purified by treatment with an alcohol such as methanol or butanol, or acetone, or an ether, and if desired steam distilled under acid, neutral, or alkaline conditions.

[Also in Division F1] A magnetic coupling between a motor 3 and a pump 4 (see Division F1) comprises ceramic magnetic rings 14, 14A mounted on plates 57 of magnetic material, such as soft iron, carried by flange portions 55, 56 and 44, 47 as of non- magnetic stainless steel. Alternatively, the cylindrical flange portions 47, 56 and plates 57 are omitted and the rings 14, 14A are bonded directly to flange portions 44, 55 of magnetic material, such as soft iron. A closure diaphragm 8 for a chamber 27 is preferably of non-magnetic electrically-non-conductive material such as fibreglass-reinforced epoxy resin to eliminate eddy current losses of the coupling, but for some applications it is of stiffer material such as nickel alloy. Pumped fluid is circulated through the pump bearing clearance, the chamber 27 and shaft passages 31, 32 back to the main flow for cooling and lubrication purposes. A similar pump is similarly coupled to the other end of the motor shaft.

Title: Liquid detergent compositions
Inventor: JONES THOMAS GWILYM
IPC: C11D3/14
Filed: 1959-06-05
Abstract: An aqueous detergent composition comprising (a) a non-acidic alkali metal salt of a phosphoric acid having a molecular weight below 400, (b) an aniomic detergent, and (c) a fatty acid alkanolamide, contains a finely divided water-insoluble abrasive material in stable suspension.  The phosphate (a), which comprises 2-45% of the liquid medium, is preferably sodium or potassium pyrophosphate or tripolyphosphate.  The detergent (b) is preferably a mixture of soap with an alkylaryl sulphonate such as sodium dodecylbenzene sulphonate, an alkly sulphate, or an acylaminoalkane sulphonate, but acyl isethionates are not recommended; the weight ratios of synthetic detergent to soap should be 1:1 to 4:1.  In general, component (b) should comprise 1-10% of the liquid medium, but if no soap is present, the synthetic detergent should not be less than 3%, and if no synthetic detergent is included, the soap should not be less than 1,2%.  Although component (c) may consist of an isopropanolamide, a glycerolamide or a tris-(hydroxymethyl)-methylamide, it is preferred to use the mono- and di-ethanolamides of lauric acid in amounts of 1-10% of the liquid medium.  The abrasive may consist of felspar, pumice, kieselguhr, emery, or carborundum, but is preferably silica, and is suitably of such a particle size that it all passes a sieve of 104 micron mesh and 80% at least passes a sieve of 53 micron mesh; coarser abrasive particles may however be used for special purposes. In general the abrasive constitutes 20-50% of the total composition. The compositions, which may also include sodium carbonate, bicarbonate and sulphate, borax, germicides such as p-chloro-m-cresol and bis- (3:5:6-trichloro-2-hydroxyphenyl)-methane perfume, such as pine oil, and colour, should not contain any hydrotrope such as sodium xylene sulphonate.  The ionic components present may be used in the form of the alkali metal, ammonium, or substituted ammonium salts.  The compositions are prepared by heating and stirring the phosphate with twice the weight of water to 60 DEG  C., cooling to 40 DEG  C., adding the solution obtained by dissolving the detergent in the rest of the water at 60 DEG  C., cooling to 40 DEG  C., and then adding successively the alkanolamide, the abrasive, and any other ingredients.  In the Provisional Specification no limit is imposed on the molecular weight of the phosphate (a), and the alkanolamide (c) may be replaced by any non-ionic surface active agent, several of which are specified.
