Abstract: 1,056,325. Inking-apparatus. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. Aug. 4, 1964 [July 19, 1963], No. 30478/64. Heading B6C. An inking roller is supported on bearings in a bearing holder 5 (Figs. 2 and 3, not shown) mounted displaceably by means of a toggle joint 7, Figs. 1 and 2 (not shown), on a guide column 6 which is shiftable vertically by means of a nut 11 on a bearing plate 1 pivoted on the machine frame by a pivot 2 and adjustable angularly by means of an eccentric bolt 3 mounted in the frame. A roller lock 8 is rotatably secured to the holder 5 and is provided with an opening handle 9. The column 6 can be adjusted vertically after screws 10 have been loosensed. After unlocking the toggle joint, the roller can be lifted off in the direction of the column from any point within the trapezoidal zone of adjustment produced by the movements of the column and the plate 1. For countering abnormal pressure which might destroy the roller, one of the toggle levers is deformed to allow yielding of the roller in the lift-off direction. A spring 12 supports the locking in the working position and assists the movement of the toggle levers into unlocking position at the end of this movement. Load on the holder is taken up in one direction by a collar on the guide column and in the other direction by loading of the toggle levers.

[Class 7 (iii)] In passing combustible mixture through a heated reaction chamber, the heavy hydrocarbon particles are separated therefrom and converted into light hydrocarbon gases by catalysts disposed in a separate chamber, the gases being carried by a stream of air or steam, or both, back into the main mixture stream. An arcuate, tubular reaction chamber 1, lined wholly or partly with chromiumnickel steel 5 and cast in one with the exhaust manifold 16, receives mixture from a carburetter through a port 4 in its shortest side, the fuel in the mixture being thereby "gasified " as it is drawn towards a pair of outlets 3 leading to the engine cylinders. The casting adjacent the outlets 3 is provided with a pair of catalyzing chambers 2 heated by the exhaust gas which are fed thereto by pipes 17 and discharged through a common pipe 18. Each chamber contains screens 6 .. 9 formed respectively of platinum, aluminium, chromiumnickel steel and platinum, and the uppermost screen 9 is pivoted eccentrically to tilt about an axis at right angles to the longitudinal median plane of the reaction chamber 1. With a small mixture flow through the reaction chamber 1, the screen is tilted upwards by a balance weight 9<11> and assists the catalyzing action of the chamber 1, but rapid flow thereof swings the screen to an horizontal position. The screen is supported on a vertical tube 10 having lateral orifices 11 through which secondary air, or steam, or both, are drawn into the chamber past a valve 12 operated conjointly with the throttle valve.

Patent GB-957136-A (GB)
Title: Improvements in or relating to novel paper sizing process
IPC: D21H17/16
Filed: 1962-08-10
Abstract: The water resistance of paper is improved by dispersing in the paper pulp a sizing agent consisting of a cyclic dicarboxylic acid anhydride of formula <FORM:0957136/D1-D2/1> where R represents a di- or tri-methylene radical and wherein R1 is a hydrophobic group containing more than 5 carbon atoms selected from alkyl, alkenyl, aralkyl or aralkenyl groups. Substituted succinic and glutaric acid anhydrides fall within the above formula.  Intimate and uniform dispersion of the sizing agent within the paper pulp is important and may be achieved by agitation, by addition of the sizing agent of the form of an emulsion or by the simultaneous addition of a dispersing agent. The sizing agent is preferably added to the pulp in conjunction with a cationic agent which improves the retention in the paper pulp of the sizing agent as well as serving to bring it into intimate contact with the fibres.  The cationic agent agent may advantageously fulfill the additional function of emulsifier for the sizing agent and suitable compounds for this purpose include primary, secondary, tertiary, and quaternary amine-modified starches, certain nitrogen substituted starch derivatives as well as certain sulphonium and phosphonium starch derivatives.  Other cationic agents include alum, aluminium chloride, long chain fatty amines, sodium aluminate, polyacrylamide, chomic sulphate, animal glue, certain thermosetting resins and polyamide polymers. Non-cationic emulsifiers which may be used to emulsify the sizing agents include such hydrocolloids as ordinary starches, non-cationic starch derivatives, dextrines, carboxymethyl cellulose, gum arabic, gelatin and polyvinyl alcohol. In addition certain surfactants such as polyoxyethylene sorbitan trioleate. polyoxyethylene sorbitol hexaoleate, polyoxyethylene sorbital laurate, and polyoxyethylene sorbitol oleate laurate may be used as emulsifiers.  The sizing agents are normally added in amounts ranging from 0.05  to 5% of the dry weight of the pulp and the cationic agents in amounts ranging from 0.5 to 2.0 parts per 1.0 part by weight of the sizing agent.  The water resistance of the paper may be further improved by post curing of the finished paper sheet.  The sizing agents may be used in conjunction with other sizing agents, fillers, pigments or additives such as alum. Specification 765,880 is referred to.
