Abstract: 413,320. Calculating - apparatus. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London. Jan. 13, 1933, No. 1153. Convention date, Jan. 14, 1932. [Class 106 (i).] Column-spacing.-A calculating, statistical, or like machine is provided with driving-mechanism for moving the paper-carriage to-and-fro during a single cycle of operations, and a selectively operated device for coupling the paper-carriage to the driving- mechanism for a single cycle. The mechanism allows for example a total to be printed in a column at one side of the column containing the items. In the mechanism shown in the Figure, the carriage 10 of the statistical machine described in Specification 299,014, [Class 106 (i)], is geared to a shaft 9 having a bevel-wheel 13 for engaging either of a pair of bevel-wheels 14, 15, on a sleeve 16 which is feathered on a shaft 17 and can be moved by means of a hand-lever 18. A loose pinion 6 on the shaft is periodically coupled thereto by means of a clutch 20 operated by an electromagnet. The pinion 6 engages a pinion 4 connected to a pinion 4a engaging a pinion 5a which is connected to a pinion 5, the pinions 4, 5, co-operating with sectors 23, 24, on a disc 8 secured to the total-printing shaft 7. The mechanism is mounted as a unit on a plate secured to the casing of the printing-mechanism. During the total-printing cycle, the shaft 7 makes one revolution, the sectors 23, 24 rotate the pinions 4, 5 successively and in opposite directions, and, if the clutch-magnet is energized, the carriage is moved one column to the right or left, depending on which of the bevelwheels is engaged, and is then returned. The movement of the carriage occurs during positioning of the types, and causes totals to be printed a column to the left or right of the items. A small gap between the sectors causes the carriage to pause during operation of the hammers. The sectors can be changed to vary the carriage-movement. The clutch magnet may be included in the circuits of the zerobutton magnets described in the abovementioned Specification. The circuits may be so arranged that the clutch magnet is energized at each total printing operation or only when major or positive totals are printed, so that minor or negative totals are printed in one column, and major or positive totals in a different column.

Title: Emulsion polish systems
IPC: C08L25/06
Filed: 1963-10-24
Abstract: Alkali soluble polymerized partial esters having monovinyl aromatic groups and allyl groups connected by ester linkages to dicarboxylic acid residues having free carboxylic acid radicals thereon may be prepared by reacting a polyol derived from a copolymer of a monovinyl aromatic compound and allyl alcohol with certain selected carboxylic anhydrides. The carboxylic anhydride may be phthalic, succinic, Nadic, methyl-Nadic, tetrahydrophthalic or hexahydrophthalic anhydride.  The preferred monovinyl aromatic compound is styrene and the allyl alcohol-styrene copolymer and selected carboxylic anhydride are reacted in proportions such that the solid resin product has an acid number from 70 to 180.  This acid number can be achieved by reacting 3 to 6 moles of carboxylic anhydride with 1 mole of polyol. The polyol may be dissolved in a hydrocarbon solvent and then treated with a carboxylic anhydride.  A polish system can be produced containing the polymerized partial ester of the invention, polyethylene wax, an ethylenically unsaturated polymer such as polyvinyl chloride, polyacrylic resin or polystyrene, levelling agents, materials to reduce slipperiness and improve gloss, emulsifiers, alkaline material and water, the system having a pH of at least 7.  The polish system is normally produced by making separate water solutions of the polymerized partial ester, the polyethylene wax and the ethylenically unsaturated polymer, and then mixing them together.
