Title: Improvements relating to coin-freed vending machines
IPC: G07F5/26
Filed: 1928-11-30
Abstract: 325,848. Faulkner, G. L. and Mc- Kean, M. J., (trading as Auto Cash Chemists). Nov. 30, 1928. Delivery of articles stored in piles.-Relates to coin-freed vending machines of the type wherein a single coin release device is common to a plurality of drawers, any one of which can be selectively operated by a single coin insertion, operation of one drawer locking the others, and consists in the provision of a bell-crank connected to each drawer and engaging abutments on a common locking bar, normally locked against complete movement by a coin-releasable device, the arrangement being that initial movement of any drawer partially moves the locking bar, but further movement is prevented unless the coin-releasable device has received a coin. Each drawer has a recessed bottom 20 and a rear raised platform 21, and carries a bolt engaging a slot in a bell-crank lever 26 on a fixed pivot. The other ends of the bell cranks each engage a stop 28 on a common locking bar 3 slidable transversely of the apparatus. The locking bar has a hole engaging a post 17 projecting from a coin-receiving block 11 normally allowed only slight movement by a stirrup latch 14 carried by a fixed pivot and urged downwardly by a spring to co-operate with a step 16. If the coin block contains a coin, 18, the latch rides up the curved edge of the coin as the locking bar is moved by the pulling out of a drawer. The step thus clears the latch and allows the selected drawer to be fully opened. To prevent the other drawers being opened, the assembly has aligned locking bars 29, 30 with bevelled ends abutting against each other with slight play. Each drawer carries a plate 31 co-operating with the bevelled ends of the locking bars, the arrangement being that the plate 31 of the selected drawer, in riding down the bevelled end of its locking bar and thus shifting this transversely to open a passage between one locking bar and the next, prevents transverse movement of all other bars by taking up the play. The coin 18 reaches the block 11 by a shoot 8 and a slot in the plate 3, and on complete movement of the coin block, falls through a slot 13 into a receptacle below. Coin-action, mechanical-connection. - A coin 18 in a coin block 11 engages a. stirrup latch 14 spring pressed downwardly about a fixed pivot to raise the latch clear of a step 16 as the coin block is moved to the left. If no coin is present the latch engages the step and operation of the machine is prevented.

Abstract: 1,207,025. Aerating liquids. APAW S.A. 24 July, 1968 [24 July, 1967; 15 March, 1968], No. 35384/68. Heading B1C. [Also in Division F1] A gear pump for making an air/liquid mixture e.g. of ice cream or whipped cream has a liquid intake port 14, an outlet duct 10, and two air inlet ports 16, 116 remote from the mesh of the gears. Liquid enters the pump through a passage 313 in a plug 13 the upper sleeve-like part 15 of which has a cam profiled edge; the plug is rotatable by a lever 216 whereby the sleeve 15 forms an adjustable shutter for the inlet port 14. Thus the amount of liquid sucked in and hence the air/liquid ratio can be altered. A by-pass valve 11 opens under excess delivery pressure to connect the delivery duct 10 with the inlet port 14, the lower end 111 of the valve simultaneously closing inlet port 313 to prevent flow of mixture up the liquid supply pipe. In another embodiment, (see Figs. 4-8, not shown), the rotatable plug 13 has a sleeve (215) with a set of calibrated inlet ports (F1- F8) instead of a cam profile, and the by-pass valve has a body (111) from which depends a flexible stem (211) carrying a ball valve (311) which closes the inlet port 313.

Patent GB-763355-A (GB)
Title: Refining mineral lubricating oils
IPC: C10G71/00
Filed: 1953-12-23
Abstract: Mineral lubricating oil is refined by contacting it with hydrogen in the presence of a catalyst composed of cobalt molybdate on substantially silica-free alumina, at temperature between 650 DEG and 750 DEG F., at a pressure between 500 and 775 p.s.i.g. and at a liquid space velocity between 0.25 and 6 volumes of lubricating oil per hour per volume of catalyst.  The process is particularly applicable to the refining of naphthenic mineral lubricating oil containing undesirable aromatic hydrocarbons, sulphur, naphthenic acids and nitrogen, and results in the hydrogenation of at least a portion of the aromatic hydrocarbons and in a substantial reduction in the sulphur, naphthenic acid and nitrogen content of the oil.  The refined oil may be passed to a vacuum stripping zone, into which steam may be introduced, in order to remove gases and volatizable material.  Specification 748,154 is referred to.

Title: Improvements in or relating to conveyors
Inventor: CRISPE STANLEY WILLIAM
IPC: B65G21/14
Filed: 1962-09-28
Abstract: 1,014,490. Endless conveyers. T. & T. VICARS Ltd. Sept. 16, 1963 [Sept. 28, 1962], No. 36883/62. Heading B8A. [Also in Division B5] A device for intermittently conveying sheet material 24, comprises an endless conveyer 10 lapped about a plurality of guides divided into two groups, one of which is reciprocably displaceable longitudinally of the conveyer 10, relative to the other, at least some of the guides having a clutch mechanism associated therewith whereby some stretches only of the conveyer 10 move forwardly when the movable group of guides is projected whilst other stretches move in a similar sense when that group is retracted. The stationary group of guides comprises two rollers 18, 20 mounted on a frame (not shown) and the movable group comprises a roller 14 and inclined plate 16 mounted on a horizontal plate 12 longitudinally movable by a pneumatic, hydraulic, electrical or mechanical linkage. Upon movement of the plate 12 from the projected position of Fig. 1 to the retracted position of Fig. 2 the rotation of roller 20 or rollers 18 and 20 is prevented by a clutch mechanism and the stretch " X " of the conveyer 10 is drawn over the roller 14 and plate 16 in the direction of arrow " A." Upon movement of the plate 12 back to the projected position, the rollers 18, 20 are rendered freely rotatably by releasing the clutch means but the roller 14 is now prevented from rotating by actuation of a clutch mechanism associated therewith. This results in the upper stretch of the conveyer 10 increasing in length and conveying forwardly the sheet material 24 which in the described embodiment is dough. The latter is fed to the endless conveyer 10 from a constant velocity feed conveyer 28. When the conveyer 10 is in the retracted position, the continuous supply strip of dough forms a loop B between the conveyers and upon being sensed by detectors 30, 32 the drive mechanism for projection of the member 12 is actuated and the loop B is taken up along the upper stretch of the conveyer 10. Further detectors 34, 36 provided below the first set act to stop the drive of the feed conveyer 28 if the dough is sensed by them. A movable knife 26 is mounted above the conveyer 10 and is synchronized to cut the dough when the upper stretch of the conveyer 10 is stationary. The knife is positioned such that the leading edge of each cut piece of dough rests at the lower edge of the inclined plate 16 when the retraction operation starts. During each retraction stroke a cut piece of dough is peeled from the conveyer 10 and is deposited on to a conveyer arranged beneath the device for conveyance longitudinally or transversely to the conveyer 10.
