Abstract: 1,152,321. Packaging-machines. JACOB, WHITE & CO. Ltd. 5 July, 1966 [12 July, 1965], No. 29441/65. Heading B8C. Collapsed cartons 1 are fed from a hopper 2 by means of suction cups 19 on a pivoted bar 16, under cam control, and partially erected with the aid of breaker bars 25, on transfer to endless chains 21 which deliver each carton, held in reverse parallelogram form by the bars 25, to endless chains 5 for folding and filling. The bar 16 forms part of a frame 13b and is pivotally connected by bars 15 to a bar 13a, the frame being vertically reciprocated by a member 13 sliding in rails 14, and controlled by a cam 10 acting on a follower 11 mounted on a member 12. The frame is movable horizontally by means of the engagement of a follower 17 on the bar 16 in a cam slot 18. A plate 20, mounted on the bar 16 intermediate the suckers, serves to bow the carton and allow air to enter into it, Fig. 2 (not shown). The frame is then driven down, withdrawing the carton from the hopper, the edge of the carton striking the rounded surface 25b of the member 25, and on being lowered further, the carton, still in contact with member 25, is brought to an erected position. The bar 16 is then forced to the right by the cam slot 18, pushing the leading edge of the box under member 25. The vacuum is then removed from the suckers and the frame withdraws, leaving the carton supported on chains 21 which carry flights 22. The gap A between member 25 and chains 21 being less than the height of the carton, the carton is retained erected, Fig. 4 (not shown). The carton is then conveyed by flights 22 on the chain until it reaches a step 25a in member 25. The distance B being greater than the height of the carton, the carton springs to its rectangular form and is retained fully erect by back flights 6 on chains 5, and front flights 7 on the other chain (not shown), which abut the carton and convey it to the carton handling machine. The chains 21 may be driven continuously or reciprocably. The cartons may be delivered in a stack other than vertical. Adjustments may be made to enable larger cartons to be erected.

Abstract: 761,250. Cash registers. PREMIER CASH REGISTERS, Ltd. Oct. 27, 1954 [Oct. 27, 1953], No. 29630/53. Class 106 (1). ). A key-set and key-operated cash register adapted for multiple-item transactions has a cash drawer which may be released after a single item or a series of items has been registered. Drawer release is effected by depression of a key lever 7 carrying rollers arranged to lift a finger 46 connected to a latch 51. The key lever 7 is however blocked by a lever 111, which engages over a stud 18 in the lever 7, until the entry of a first item when a cam 19 on the revolution shaft 3 rocks the lever 111. A detent 20 then holds the lever 111 ineffective. On depression of the key lever 7, a stud 33 therein rocks levers 28 and 35 into the path of the key coupler 44 to prevent operation of the amount keys. The stud 33 co-operates with a recess 41 in the lever 35 to ensure a full stroke of the key lever 7. The lever 35 has an ear 38 engaged by a lever 54 having a tail 57 in the path of the drawer. Thus, when the drawer opens, the lever 35 is rocked to allow restoration of the key lever 7. A shoulder 58 of the lever 54 engages over the key-coupler 44 to prevent operation of amount keys while the drawer is open. When an inspection door is opened by an inserted key, a lever 59 is able to rock clockwise and cams the lever 111 slightly from its blocking position so that the drawer-release key lever 7 may be operated without previously depressing an amount key. Item and transaction counters. A transaction counter is actuated each time the drawer opens. An item counter, which is actuated each time an amount is entered, is reset when the drawer is closed. For this purpose, a roller 72 on the drawer rocks a lever 71, 74 against a stop 81. The lever is connected by a link to a segment 78 which rotates through a free-wheel mechanism a zeroizing shaft. Item totalizer. In addition to a grand totalizer, an item totalizer is actuated during each entry. The item totalizer is reset to register the complement of one unit by a segment 77 rocked through a link by the lever 71, 74 when the drawer is closed. Resetting is completed early in the next machine operation.

Abstract: 1,182,738. Removal of CO and NO from gases. PITTSBURGH ACTIVATED CARBON CO. 21 June, 1968 [13 Oct., 1967; 14 July, 1967; 19 July, 1967], No. 29661/68. Heading C1A. Carbon monoxide or nitric oxide are oxidized, when in a gas mixture, by passing the mixture through a high-surface-area support impregnated with a copper-chromium compound and/ or a mixture of compounds of copper and chromium, the chromium being in oxidation state VI, and the oxidation products thereafter removed. The impregnant may also include a silver compound, and may comprise or consist of copper chromate. Any convenient copper compound may be employed, e.g. CuO, CuCO3, Cu(OH)2. The silver compound is normally AgNO3, and any convenient Cr (VI) compound, e.g. CrO3 may be used. CO is converted, by the above process, to carbon dioxide, which may be removed using active carbon impregnated with monoethanolamine. The gases are preferably oxidized at a temperature of at least 50 C. In the removal of CO, sufficient oxygen may be supplied to the gas mixture to convert all of the carbon monoxide to carbon dioxide at a sufficiently high temperature to maintain the efficiency of the impregnated support. This oxygen may be supplied as air, and may be already present in the mixture. The support may be activated carbon, and the exhausted, impregnated support may be regenerated with an O2-containing gas, e.g. air, at an elevated temperature (e.g. 170-190 C.), and re-used.

In a process for at least partially crystallizing an extruded polycarbonate film, the extruded film is contacted, while under tension, with vapour of an organic solvent which is capable of dissolving or swelling the polycarbonate, the tension being such as to cause the film not to be deformed, or to be shrunk or expanded by at the most 10% of its original dimensions. The film may subsequently be dried and then stretched. The temperature of the vapour may be e.g. - 10 C. to 150 C. In an intermittent process the film may be contacted with the vapour while being held under tension in a frame. In a continuous process, the film may be guided by clip devices or slide rails through a vapour chamber, the change in dimensions being controlled by the speeds of feed and take-up rolls, or by the spacing of slide rails or pairs of idler rolls. The treated film may be dried by e.g. hot air or radiation, and may be calendered to improve transparency. The film may be exposed to the vapour at a low temperature and then heated to accelerate crystallization. Specified solvents are acetone, acrylonitrile, chlorinated hydrocarbons, thiophene, dioxan, benzene, xylene, ethyl acetate, ethyl butyrate and tetrahydrofuran. Examples describe the exposure of films of 2,2-di-(4-hydroxyphenyl)-propane polycarbonate to atmospheres of acetone, methylene chloride and chloroform.
