Title: Improvements in and relating to prepayment meters for gas and the like
IPC: G07F15/02
Filed: 1924-09-24
Abstract: 241,365. Taunton, R. P., and McIndoe, R. W. Sept. 24, 1924 Gas, supplying by meter. -The quantity mechanism, Fig. 1, actuating the cut-off valve lever e is attached to the meter and is connected by a " Bowden " cable t, Fig. 4, to the coin-mechanism contained in a separate accessible box 20 which is disposed apart from the meter and comprises a coinoperated ratchet mechanism and a price-changer. One end of the cable t, which passes through a tube 14, is attached to a grooved drum 13 rotated by prepayment and the other end to a drum s, Fig. 1, which is thereby rotated against the action of a spring m<1> and through a pawl drives a ratchet wheel p and a bevel wheel k. Backward rotation of the wheel k is prevented by a pawl x engaging ratchet teeth I thereon. The wheel k drives a bevel wheel j on the. slotted portion of a spindle g with which a pin on a nut f engages thereby rotating the nut to open the valve. The nut engages a separate screwed portion of the spindle g which portion is rotated by the meter through a wheel h to close the valve. The wheel j may be slid out of engagement with the wheel k against the action of a spring j<1> when it is desired to shut the valve by hand. The tubular casing 14 is secured at the meter end in a nipple 15, and the end terminating in the box 20 is received in the, head 21 of a hollow threaded rod 22 adjustably secured in a bracket 23. The Provisional Specification describes an epicyclic measuring-out mechanism. Coin action, thrust and mechanical-connection; price-changing mechanism. - A coin inserted through a slot in a stationary adjustable price-change disc 3, Figs. 4 and 7, into a carrier rotatable by an external handle 2 first depresses against the action of a spring 36 a sliding clutch plate 34 by engagement with a tongue 39 thereon, and then couples the carrier to a ratchet ring 31<1> by engagement between crown teeth 30 on the ring. The plate, 34 is slidably attached to a plate 31 located within the ratchet ring 31', and has a tooth 33 which engages the crown teealh 30 when the plate 34 is depressed thereby clutching the plate 31 and ring 31<1> together. This construction prevents the coin from binding in the teeth 30 owing to the pull of the cable t on the drum 13 which is carried by the plate 31. Backward rotation of the ratchet ring 31<1> is prevented by a pawl engaging ratchet teeth thereon. The price-changer is locked by a pin 4 and by an arm 7 projecting from a rotatable hasp 6. Coin-slit closing-devices.-A disc 11, Fig. 4, on the handle 2 closes the coin slot when the handle is rotated. This disc has a slot which registers with the coin slot when the carrier is in position to receive a coin. Casings; money-boxes or receivers.-The back 25 of the box 20 is formed as a door locked from within by a headed screw 27 passing through a hasp 26 and engaging a socket 28. Access is had to the screw 27 by removing the money-box 8 which is provided with a slot to pass over the locking hasp 6 of the price-changer before this receives a padlock.

Title: Process of peroxidizing alpha-olefin polymers
Inventor: NATTA GIULIO
IPC: C08F255/00
Filed: 1961-06-26
Abstract: A process of peroxidizing linear, non-crystallizable polymers of alpha-olefins comprises subjecting an aqueous suspension of the polymer to the action of oxygen at 40 DEG  to 200 DEG C. and under 1 to 20 atmospheres pressure.  Polymers specified are derived from propylene, butene, methylpentene, hexene and mixtures thereof with each other or with ethylene.  The oxygen may be air or an p oxygen/inert diluent mixture, and the water may contain surface active agents.  The polymer may be swollen with an inert diluent. Graft copolymers may be obtained by treating the peroxidized polymers, preferably swollen in a solvent, with a monomer which is polymerizable by a free-radical mechanism, e.g. styrene, butadiene, isoprene or vinylidine chloride.  The graft polymerization may be effected in water containing emulsifying agents, anti-foaming agents and colloids.  In Example 6 the product of grafting butadiene on to an ethylene-propylene copolymer is stabilized with phenyl-b -naphthylamine and is vulcanized with the aid of stearic acid, zinc oxide, diphenylguanidine, N-oxydiethylene benzothiazole-2-sulphonamide and sulphur.  Latices of the graft polymers are useful as paints, varnishes and sizes for fabrics. Specifications 810,023 and 856,733 are referred to.
