Title: Improvements in coin-freed apparatus
Inventor: BOURACIER CYRIL EUGENE
IPC: G07F15/12
Filed: 1961-10-20
Abstract: 944, 317. Coin freed apparatus. ICE-MATIC. Ltd. Oct. 9, 1962 [Oct. 20, 1961], No. 37672/61. Heading G4V. A coin freed mechanism, which times the actuation of a switch controlling the service provided by unspecified apparatus, has a timing disc 18 driven when an electric motor is energized by the actuation of a switch the operating arm 40 of which is deflected by a coin deposited in shoot 31, the coin being held in suspense against arm 40 by a pin 21 on the timing disc until such time as the disc moves off normal and operates a switch 24 to hold the motor energized. The timing disc has two pins 21 and notches 22 spaced in diametral opposition so that after half a revolution the cam wheel 23 operating switch 23 re-enters a notch to disconnect the motor. A cam follower 25 pivoted at 26 carries a spring 27 with an end finger 30 which is projected into the coin shoot 31 when the timing disc is off normal and thereby arrests the progress of any further coin or coins deposited in the shoot above the coin which actuates the switch arm 40. With coins arrested in this manner, return of the timing disc to a normal position lowers the cam follower 25 and admits the next coin into that part of the shoot where it operates the switch controlled by arm 40. The motor, therefore, continues to drive until the coins accumulated in the shoot, and in any associated feeding receptacle, are exhausted. The coin shoot is adjustable in width by means of the screw and slot connections 33a, 34. The mechanism may have an additional switch controlled by the notch or notches of the timing disc to operate a counter to record the number of cycles for which the mechanism has been employed.

Title: Improvements in and relating to methods and apparatus for bending and annealing glass sheets
IPC: C03B23/027
Filed: 1964-09-16
Abstract: A method of bending and annealing a glass sheet comprises supporting a limited area of the glass sheet, increasing the area of support while simultaneously heating the glass sheet through a range of temperatures sufficient for bending it, cooling the glass sheet to substantially the top of its annealing range of temperatures, thereafter decreasing the area of support of the glass sheet by removing a portion only of said support from contact with the glass surface, and maintaining the portion of the support in spaced relation to the glass sheet surface until the glass sheet is cooled to the bottom of its annealing range of temperatures. A glass sheet is passed through a heated lehr having heating, bending, annealing and cooling zones on a conventional type sectionalized bending mould 20.  The mould comprises a centre section 22 and movable end sections 24 with associated counterweight 26 and pigtails 25.  The whole is mounted upon a frame 19. A cam follower comprising a U-shaped member 28 is pivotally attached by the legs at its open end to the frame 19 and has a wheel 30 rotatably mounted upon an axle between its legs, the <FORM:1016950/C1/1> <FORM:1016950/C1/2> web of the U-shaped member forming an abutment for engagement with the pigtails 25. After the mould with a glass sheet has passed through the bending section it enters the annealing section of the lehr.  The wheel member 30 contacts and rides up an upwardly inclined portion of a cam monorail 32 extending the length of the annealing section, thus bringing the member 28 into contact with the pigtails 25 and raising them sufficiently to cause the mould end-sections 24 to be rotated away from the surface of the glass sheet.  At the end of the annealing section the monorail has a downwardly inclined portion thus causing the end mould sections to be brought back into contact with the sheet. The monorail is supported for horizontal and vertical adjustment just above the level of the conveyer rollers, and the wheel 30 may be placed in varying positions along the length of the member 28 depending upon the distance it is required to move the mould and sections 24 from the glass sheet.

Title: Improvements in and relating to the preparation of oxidation products of hydrocarbons
Inventor: SMITH PETER
Filed: 1960-11-09
Abstract: A process for the oxidation of nonaromatic hydrocarbons to compounds containing oxygen, including alcohols, comprises reacting a non-aromatic hydrocarbon with free oxygen or a gas containing free oxygen in the presence of a borate ester, the corresponding alcohol of which is more volatile under the reaction conditions than is the alcohol produced in the oxidation reaction, the said alcohol produced reacting with the borate ester to liberate the more volatile alcohol, which is removed from the reaction mixture, the product alcohol being subsequently recovered from the borate ester formed.  The alcohol corresponding to the initial ester preferably contains at most 3 carbon atoms whilst the hydrocarbon preferably contains 3-20 carbon atoms. The conversion of the hydrocarbon is preferably not more than 30% and temperature preferably in the range 50 DEG C. to 200 DEG C. When cyclohexane is oxidised by the above process to cyclohexanol, cyclohexanone is produced as a by-product, the yield of which may be improved by rapidly cooling the reactants after completion of the oxidation process. Examples describe the oxidation of (1) n-decane to primary and secondary n-decanols, mainly the latter, and decane-diols; (2) and (14) n-dodecane to mainly secondary dodecanols; (3) dodecane, (9) methylcyclohexane, (10) n-octane, (11) iso-octane, (12) commercial di-isobutylene and (13) n-pentane to mixtures of alcohols; (4)-(8) cyclohexane to cyclohexanol and cyclohexanone.  The borate esters used in the examples are: (1) and (2) n-propyl orthoborate; (3)-(13) methyl orthoborate; (14) n-propyl metaborate. The more volatile alcohol which is distilled off may be used to make further borate ester.
