Title: Improvements in coin-freed vending machines and the like
IPC: G07F11/18
Filed: 1932-08-15
Abstract: 399,303. Coin-freed article-delivery apparatus. SALTER & CO., Ltd.,.G. and CALDWELL, T. F., 144, High Street, West Bromwich, Staffordshire. Aug. 15, 1932, No. 22783. [Class 27.] Articles stored in piles; fraud, preventing.- The recessed delivery drawer 2, Fig. 1, of a coin-freed articledelivery machine carries a movable pile support and ejector 3 which pushes the bottom article of the pile 1 to the front of the drawer, when this is pulled out, and closes the drawer aperture 11 thereby preventing fraudulent abstraction of other articles. The member 3 is fixed to a bottom plate 3a having a guide-bar 4 engaging a correspondingly shaped slot 5 in the bottom of the drawer 2, the bar 4 being enlarged to prevent the member 3 from rising. When the drawer is pulled out, a lever 7 pivoted thereto at 7a, Fig. 4, moves the member 3 forwardly against the action of a spring 6, one arm. of the lever engaging behind the member 3 and the other arm engaging a recess 8 in the side frame 9 in which the drawer slides. The first movement of the drawer causes the member 3 to push the bottom article to the front of the drawer, but, when the lever 7 leaves the recess 8, the member 3 and drawer 2 move as one. A pair of studs 12 fixed to the drawer assists in supporting the pile.

Title: Plasticizer for polyvinyl chloride resins
Inventor: JACOCKS CLAUD LEIGH
IPC: C08K5/12
Filed: 1961-06-28
Abstract: A mixture of phthalate esters containing by weight 15 to 30% n-hexyl, 30 to 40% n-octyl and 40 to 50% n-decyl phthalates, prepared by combining the appropriate alcohols with phthalic acid or anhydride (see Group IV(b)), is stated to be suitable as a plasticizer for polyvinyl acetate, polyvinyl chloride, polyvinyl chlorideacetate, polyvinyl butyral and polyacrylates.  The ester mixture is incorporated into the resinous material in an amount of 50 to 100% based on the weight of the polymer.  Stabilizers, e.g. the cadmium and barium salts of carboxylic acids, and epoxy compounds, may be incorporated into the resin along with the plasticizer.ALSO:The invention comprises a mixture of phthalate esters containing by weight 15% to 30% n-hexyl, 30% to 40% n-octyl and 40 to 50 n-decyl phthalates which is useful as a plasticizer for resins (see Group IV(a)).  The ester mixture is prepared by combining 0.5 to 1.5 moles of n-hexanol, 0.5 to 2.5 moles of n-octanol and 0.75 to 2.5 moles of n-decanol with 1 to 3 moles of phthalic acid or anhydride.  The reaction may take place at 90 to 110 DEG C. at atmospheric pressure and generally takes from 2 to 4 hours.  An organic solvent, e.g. benzene, toluene, xylene or cumene, may be used to facilitate the reaction.  The reaction may be initiated with sulphuric acid.  After esterification the reaction mass may be passed over a dehydrating agent, e.g. calcium chloride or activated alumina, or washed with water and with 5% sodium carbonate and then dried with anhydrous sodium sulphate. Thereafter the organic solvent with or without unreacted alcohols, if any, is removed by distillation and the remainder of the reaction mass subjected to a separation treatment, preferably by distillation under a vacuum, for the recovery of the ester product.  The mixture of esters produced may be treated with a decolourizing agent, e.g. Attapulgus clay.
