Abstract: 382,793. Liquid measuring and dispensing apparatus. GETAZ, E., 126, Berea Road, Durban, South Africa. Dec. 8, 1931, No. 34003. Convention date, Sept. 18. [Classes 27 and 106 (v).] A coin-operated liquid dispensing and measuring device comprises a ported plug 4, Figs. 1 and 3, attached to the liquid reservoir by a nut 19 and having secured to it by a pin 14 the boss 5 of a flanged disc 1. Another flanged disc 2 is secured to the disc 1, a slot being left between the discs so that a handle 10 may be moved to and fro through 90‹ to rotate a sleeve 7 closely fitting the plug, and provided with a flange 32 located between the discs 1, 2. A cylindrical glass measuring vessel 6 moving with the sleeve 7 is clamped between the flange 32 and a coned washer 22 by a nut 22 screwed on the end of the sleeve, rubber packing pieces being provided between the vessel 6 and the parts 32, 22 and between the washer 22 and the nut 21. A bell-mouthed guard 20 is also screwed on the end of the sleeve. The parts may thus be readily dismantled for cleaning purposes. The plug 4 has two ports 24, 23, the port 24 leading to a discharge nozzle 31 and the port 23 communicating with the liquid reservoir through a bore 15. The sleeve 7 has ports 8, 9 which co-operate with the ports 23, 24 and through which the measuring vessel is filled and discharged respectively when the sleeve is rotated. Bent holes 25 are provided in the plug to register with corresponding vent holes in the sleeve, air passing to the measuring vessel through a passage 17 when the vessel is being emptied, and from the vessel through a bore in the plug and a vent pipe in the reservoir, when it is being filled. The handle 10 may be attached directly to the flange 32 of the sleeve, or may be coupled to it by a coin. Coin action, mechanical-connection.-When the sleeve is coin-operated, the handle 10 has a forked end 39 with projections 42 engaging opposed slots 40 in the discs 1, 2, Fig. 12, which is an underside view. A coin 44 inserted through a slot 11 rests in the fork 39 and engages a curved recess 45 in the flange 32 to couple the sleeve 7 and handle 10 together. After the handle is turned through 90‹, a spring 49 ejects the coin to a money-box 12 depending from the disc 2. The flange 32 has projections 43, 47 which limit its turning movement, the sleeve being returned to initial position, after discharge of the coin, by the handle engaging the projection 43. Fraud, preventing.-A projection 60 on a curved stop 50 engages behind the coin and prevents return of the handle after a partial stroke. The stop 60 also engages the neck of the projection 43 and prevents the sleeve from being rotated in the absence of a coin. Money-boxes.-The money-box 12 is detachably secured to an extension of the disc 2 by a bayonet-joint 29. It is sealed in position against unauthorized detachment. The box has a series of inspection holes 28 to enable the number of coins to be computed.

Patent GB-1082532-A (GB)
Title: Process for treating hydrocarbon oil
IPC: C10G71/00
Filed: 1964-08-21
Abstract: Petroleum wax and lubricating oil are obtained by subjecting a hydrocarbon feed to catalytic cracking or to coking, fractionating the product to recover a lubricating oil fraction, solvent extracting to remove aromatics and olefins and subjecting the raffinate to a dewaxing step to recover a lubricating oil and a wax; in the case of catalytic cracking of the feed, at least part of the heavy cycle oil boiling below the lubricating oil fraction is recycled to the cracking.  Cracking is effected at 900-1050 DEG  F. and 10-50 p.s.i.g. or the coking at 800-1000 DEG  F. and 10-100 p.s.i.g., and the fraction for further treatment should contain at least 90% of material boiling above 550 DEG  F. Solvent extraction is preferably effected first with furfural, sulphur dioxide, dimethylsulphoxide, chlorex or phenol and dewaxing is then effected by mixing the raffinate with methylethylketone and toluene and cooling.  The oil product is acid- and clay-treated. The wax may be deoiled by a second treatment which also yields a soft wax, and then percolated through clay.

Patent GB-344054-A (GB)
Abstract: 344,054. Calculating-apparatus; checking receipts. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.- (Assignees of Sburlino,P.; 452, Forest Avenue, Dayton, Ohio, U.S.A.) Dec. 2, 1929, No. 36863. Convention date, March 1. [Class 106 (i).] Cash registers with operating-means multiplying by repetition.-A calculating machine, cash register &c. is provided with two release keys, one for releasing the machine when repetition is desired and the other for use when the item is not to be repeated. By depression of a further key the repeat release key may be temporarily converted into a non-repeat release key. The invention is illustrated as applied to the Shipley type of cash register described in Specifications 8119/15 and 176,781, [both in Class 106 (i), Calculating &c.]. The usual key-releasing bail 55 is now loose upon the release shaft 56 so that when the right-hand release key 34 is used for freeing the machine for operation the bail is not rocked to release the set keys and the item set may therefore again be entered by a second operation. If the keys are to be released however at the end of the operation, the left-hand release key 35 is depressed and this besides releasing the machine for operation, couples the bail to the shaft to cause key release. For this purpose the key 35 rocks a lever 141, Fig. 4, to force a coupling slide 143 further over the release shaft 56 to bring a stud 145 on the slide into position to operate the bail. The slide engages in kerfs at diametrically opposite points of the shaft and is urged outwards by a spring 144. To convert the right-hand release key 34 into a non-repeat key a special key 36 is depressed to effect the same coupling action through a bar 172. This key remains locked down by a detent 175 until by depression of the non-repeat key 35 this detent is displaced to free the key.

Title: Half tone drop-out process
IPC: G03F1/54
Filed: 1945-12-27
Abstract: 617,169. Photo-mechanical processes. BERRY, B. L. Dec. 27, 1945, No. 34963. [Class 98 (ii)] [Also in Group XL (a)] Half-tone screen negatives to be used for reproductions in which the high light areas are free from screen dots are made by providing a copy formed on a surface treated with a fluorescent material which emits an actinic light upon irradiation and photographing this copy through a half-tone screen on to a photographic plate in the regular manner, irradiating the copy as with invisible rays such as ultra-violet, cathode- or X-rays, and re-exposing the plate using the light emitted by the uncovered fluorescent areas. The copy may be made on a surface treated with a phosphorescent material and the re-exposure effected by light emitted from the uncovered areas after the normal exposure light has been shut off. The screen may be moved further away from the plate, or removed entirely, during the irradiating exposure. The order of the two exposures may be reversed. Fluorescent materials may be ground up, mixed with a liquid containing a binder such as gelatine and gum arabic to form a paste or paint which is applied to the surface of drawing paper, artists' board or canvas as by brush or spray and the copy produced by drawing in line, wash, crayon or pencil on to this preferred surface, leaving the high lights uncovered. Water-colour paint, when used to prepare such copy, may include an ultra-violet-ray absorbent such as Brilliant Green or Saffronine Red to prevent reflection of ultra-violet-rays from the copy on to the photographic plate. Alternatively, an ultra-violet filter may be used on the camera lens. The fluorescent materials are described as, barium sulphate or zinc sulphide copper activated and dampened with nickel; sulphides of calcium, strontium, barium and zinc generally combined with a minute quantity of bismuth or thorium oxide, anthracene, eosine and thioflavine; and the phosphorescent materials are described as zinc phosphor or calcium phosphor activated either with bismuth or cadmium. A material which is both phosphorescent as well as fluorescent to invisible or deep violet radiation may be used. The method may be applied to photographs by treating the latter with a thin liquid solution or suspension of the fluorescent material which will be more luminous in the high lights when irradiated, since much of the fluorescent quality penetrates in and is lost in the darker portions of the photograph. Specification 617,170 is referred to.
