Abstract: 479,546. Ticket-cancelling machines. FISHBURN, J. E., and WARD, A. W. Nov. 10, 1936, No. 30662. [Class 106 (iii)] A machine for cancelling tickets in a theatre, kinema, or like establishment comprises devices for feeding a strip of tickets in the machine, for severing each ticket into at least two portions, and for ejecting one portion : preferably a serial number is printed on the retained portion. The ticket is placed in an aperture 2 which is provided with an adjustable stop to prevent the entrance of a ticket of more than predetermined thickness or of a foreign body ; the stop is of such a size and is arranged in such a position that it co-operates with the notch in the edge of a ticket so as not to interrupt the feed of a ticket with a slightly bent edge. The ticket may close the switch of a,n electric motor or a separate control may be provided whereby feed rollers are set in motion to feed the ticket to a stop 9. The ticket rocks an arm 12 connected by a link 15 and lever 16 to a plate 10 mounted in a slot in the plate 1 over which the ticket moves. If the ticket is of normal length, the plate 10 is held depressed after the leading edge has passed the stop 9 to permit the ticket to he fed to a stop 19 ; otherwise ticket is deflected into a receptacle. The stops 9, 19 are actuated by connected bellcrank levers 21 roched by a crank 24. The ticket passes over a switch 40 adapted to rock an arm 44 connected to a pivoted lever 37, which is therefore moved into the path of a yoke 33 on the frame 28 of the number-printing apparatus 27. The apparatus 27 is reciprocated continuously during the operation of the motor by meaus of a crank-pin 30, but the number printing-wheels are only changed on the downward movement after the yoke 33 has been engaged by the lever 37. An inking- roller 70, carried by a frame 71 and rocked by a pin 74 on the frame 28 normally lies in contact with the printing-wheels, but on movement of the frame 28 is rocked into contact with a roller 75 formed of porous material impregnated with ink. The roller 75 is mounted in a pivoted frame 76 having a leg 77 engaging a shoulder on a spring-pressed lever 79 so that the roller 75 is held resiliently towards the roller 70. The ticket is held stationary during printing, and is then fed forward to a stop 50, in which position it is cut into two portions and separated from the succeeding ticket of a strip alternatively, a cutter for separating the tickets may be provided adjacent the stop 9. The cutter comprises knives 51 carried by a block 52 reciprocated bv the crank-pin 30. The portion carrying the serial number is delivered to a removable receptacle 59 wherein it is packed by a reciprocable member 61 against a spring strip 60, which is depressed until it closes contacts 64 of a signal lamp 65. The number of operations of the machine is recorded on a counter 82 actuated by the lever 37, and a visible or audible warning- signal 87 is actuated each time the counter is operated.

Polyethylene, polypropylene and polybutylene imines are mentioned and the poly-imine contains 3-150 repeating units, and is preferably such that a 50 wt. per cent dispersion in water has a viscosity of 50-5000 poises at 25 DEG  C.  The fatty acid contains 6-20 carbon atoms.  In Example 1 a salt is prepared from a polyethylene imine having as a 50 per cent aqueous solution a viscosity of 850 poises at 25 DEG  C. by refluxing an aqueous solution with coconut oil acids of average molecular weight 220. Benzene was added as an azeotroping agent for removal of water.  The products are used as pour point depressants for oil.  In Example 2 the salt of Example 1 is used in admixture with a condensate made by alkylating naphthalene with a chlorinated wax.ALSO:A minor proportion of a fatty acid salt of a polyalkylene imine (see Group IV(a)) is added to a lubricating oil as a pour point depressant.  Preferably the polyalkylene imine is such that a 50 wt. per cent, dispersed in water has a viscosity of 50-5,000 points at 15 DEG C., and the fatty acid is one with 6-20 carbon atoms. In Example 1 a salt of polyethylene imine with mixed coconut oil acids is added in varying proportions to an extracted Mid-Continent SSAE 20 bar stock.  In Example 2 a mixture of this same salt with a condensate from naphthalene and chlorinated wax, is used in the same way.  The pour point depressants are preferably dissolved in mineral oil to form concentrates which facilitate the addition of small quantities of the salt to lubricating oil.
