Title: Improvements in machines for sharpening rotary cutters
IPC: B24B3/02
Filed: 1959-08-29
Abstract: 885,434. Sharpening rotary cutters. ROWLEY, A: S. Aug. 19,1960 [Aug. 29,1959], No.29565/59. Class 60. In a machine for sharpening rotary cutters the cutter A, Fig. 1, is mounted on an arbor B carried in a frame D supporting a grinding wheel C and is automatically rotated by a single-tooth pinion mechanism after each grinding operation to bring a succeeding cutter tooth into the grinding position, the grinding wheel being mounted for reciprocation on a slide c by a crank 13. The crank is manually or motor-driven by a shaft 1, Fig. 2, which also intermittently drives the arbor B through bevel gears 9. A single-tooth pinion 3 on the shaft 1 advances the cutter by one tooth at each revolution, through gearing 5, 8, appropriate to the number of cutter teeth, and through gearing 12 and a shaft 11, effects one cycle of grinding-wheel sliding motion between cutter movements. The feed may be adjusted during cutting by a divided arbor-driving shaft, the separate portions 7, 7<SP>1</SP>, Fig. 3, being, connected through a planetary gear, the sun-wheel 19 being secured to the driven portion and the planet wheels being mounted on spider 17<SP>1</SP> which is secured to the driving portion 7; a toothed ring is secured to the planet gear-housing which is itself rotatable by a worm wheel 18<SP>1</SP>, engaged by a worm 18 manually rotatable through reduction gearing 22 by a handwheel to vary the relative angular positions of the two portions of the shaft, and thus to adjust the arbor and cutter relative to the grinding wheel.

Abstract: 1318567 Coin-freed vending apparatus MM JENKINS 23 June 1970 [9 July 1969] 30428/70 Heading G4V A coin handling device, which is associated with a vending machine, has a number of coin shoots each arranged to receive coins of a particular denomination, for example 5c, 10c or 25c, sensor means adjacent to the shoots to sense the presence of coins and activate a totalizer, and stop means for holding coins in the shoots during totalization, and operable to release coins from the shoots corresponding to the price of an article vended. The sensor means may comprise switches or photo-diodes (Fig. 11, not shown). The embodiment described is comprised of adjoining segments each adapted to receive one coin denomination (Figs. 1, 2, 3, not shown) from a coin tester and separator. The figure illustrates the segment that receives 10c coins and the two other segments for 5c and 25c coins are similar in construction (Figs. 4, 6, not shown). Adjacent to the coin shoot 32 are switch means 33, 34 and 35 which sense the 10c coins, D, inserted. The first 10c coin is brought to rest adjacent switch 33 by the stop 46. A member 36 is rotated about pivot 37 and a projection 40 engages an arm 41 of the switch and moves it from the normally closed contact 43 into engagement with normally open contact 42. The pivotal movement of member 36 is limited by detent 44. If a second coin is inserted it is brought to rest by engagement with a projecting stem 39 of the switch 33 and in this position operates switch 34. Similarly a third coin actuates switch 35. The switches 33, 34, 35 and corresponding switches in the 5c and 25c segments are connected to AND gate or typical relay circuitry (Figs. 7, 8, not shown) which totalizes the value of the coins held in the shoots. When an item is purchased the stops 46, (24), (50) are temporarily withdrawn by solenoid actuated devices (Fig. 9, not shown) to allow coins of value equivalent to the vend price to pass to a cash box or change pay out tube. Further stops (not shown), positioned to retard the second coins in the shoots, may be moved into the shoots as the lower stops are withdrawn, allowing only one coin at a time to pass. The credit represented by the coins in the shoots may then be re-evaluated and a further item purchased, if required, or the remaining coins may be returned to the purchaser.

Title: Improvements in or relating to the treatment of synthetic continuous filament yarns
IPC: D06M15/227
Filed: 1961-08-23
Abstract: The durability of synthetic continuous filament yarn, e.g nylon and "Dacra" (Registered Trade Mark), is increased by coating it with an oxidized polyethylene wax.  Suitable oxidized polyethylene waxes are those having molecular weights between 1000 and 3000 containing at least 3% of oxygen based on the weight of the oxidized wax and having acid numbers of not more than 50 prepared by subjecting polyethylene/alkanol telomers in the liquid phase to the action of an oxygen containing gas.  The oxidized polyethylene wax may be applied to the yarn dissolved in a hydrocarbon or halogenated hydrocarbon solvent, e.g. toluene, xylene, naphtha (boiling range 93 DEG -149 DEG C.), trichloroethylene, carbontetrachloride, cyclohexanone and turpentine, or as an aqueous emulsion containing as emulsifiers mixtures of higher fatty acids, e.g. saturated aliphatic acids containing 12-20 carbon atoms, with volatile amines, e.g. morpholine, methoxy propylamine and 2-amino-2-methyl-1-propanol, long chain alkyl aryl sulphonates, alkyl aryl polyether alcohols or condensation products of ethylene oxide with long chain aliphatic alcohols, acids, esters, ethers or alkyl phenols, either before or after drawing. After application of the solution or emulsion of the oxidized polyethylene wax the yarn may be heated, e.g. to a temperature above 100 DEG C., to remove the water or other solvent. Emulsions containing 5-20% by weight of the oxidized polyethylene wax are preferably used and 0,05% by weight or more of the wax is preferably applied to the yarn.  The oxidized polyethylene wax may be applied to the yarn together with antistatic agents, e.g. alkylphenolethylene oxide condensation products, mineral oils or silicones.  The yarns may be made into ropes by laying together a plurality of yarns, e.g. 70-80 or more, in a left hand direction, i.e. with a "S" or left hand "lay" or twist, and plying the desired number of strands, usually 3 or more, to form a rope with a "Z" twist or "right lay".

Abstract: 624,449. Electric condensers ; anodic coating of aluminium. PHILIPS LAMPS, Ltd. Oct. 14, 1946, No. 30570. Convention date, April 12, 1943. Drawings to Specification. [Classes 37 and 41] An alternating current electrolytic condenser comprising two or more electrodes each provided with a dielectric oxide film covered with an amorphous oxide film permeable to the electrolyte, is provided with electrodes of aluminium having a purity of at least 99.9 per cent. The aluminium foils are cut into sizes 35 Î 5 cm. and 200 microns thick, superficially cleaned, and if desired, etched to increase the active surface. Subsequently, an amorphous porous oxide film is applied by means of an electro-chemical treatment in a solution of 100 g. of chrome oxide and 100 cm. of sulphuric acid in 4 litres of distilled water. The direct current used is this treatment being of such a value that a current of 4 amps flows in each foil of the above-mentioned size. This treatment is effected at room temperature and is carried out for about 10 minutes, giving a film of about 4 microns thickness. Subsequently a crystalline dielectric oxide film is produced under the amorphous film by dipping the foils into a bath of the composition 40 grams B 2 O 3  and 1.5 cu. cm. of ammonia 13 cm. dissolved in 1 litre of distilled water and by forming with direct voltage. Specifications 397,538, 398,825 and 617,542 are referred to.
