Patent GB-370099-A (GB)
Abstract: 370,099. Calculating - apparatus. MARCHANT CALCULATING MACHINE CO., Oakland California, U.S.A.-(Assignees of Friden, C. M. F. ; Piedmont, and Lerch, G. ; Oakland, both in California, U.S.A.) Feb. 6, 1931, No. 3858. Convention date, Feb. 8, 1930. [Class 106 (i).] Interlocking.-A machine with a longitudinally movable carriage is provided with means to lock the carriage against displacement during the time the actuator is out of full cycle position and to prevent operation of the machine when the carriage is being shifted. The means described comprises a locking member operated by the driving mechanism and a latch for holding the member in locking position. The machine shown, Figs. 1 and 2, is of the type described in Specification 229,642, [Class 106 (i), Calculating &c.], with a rotary actuator 300 driven through a reversible transmission gearing and clutch from a drive shaft 100. Keyed to the shaft 104 of the transmission gears is a cam disc 597 having a recess normally engaged by the nose of a spring controlled cam lever 598. When the shaft 104 is rotated the cam lever is rocked and its upper end 5984 is projected into one of the slots 4010 of a plate 401 secured to the totalizer carriage thereby locking it against movement. While the carriage is being shifted the plate 401 acts as an abutment for the lever 598 so as to lock the cam disc against rotation. To hold the cam lever 598 in locking position during a number of cycles a latch lever 599, Figs. 1 and 4, is provided. This lever is pivoted to a frame plate and has two arms 5992, 5994 arranged at right-angles. The arm 5994 co-operates with a pin 1151 on the usual clutch control lever 115 so that when the lever is rocked to throw in the clutch the arm 5994, under spring action, follows the movement of the pin and the other arm 5992 moves behind the cam lever 598 to hold it in locking position.

Title: Improved manufacture of cellulose acetate composition of low inflammability
IPC: C09D101/12
Filed: 1929-12-03
Abstract: Cellulose acetate is mixed with phosphoric acid in the presence of a solvent or mixture of solvents to form solutions from which non-inflammable films, lacquers, and varnishes may be obtained. Any of the phosphoric acids may be used such as ortho-, pyro-, meta-, or hypo-phosphoric acid.  In an example, cellulose acetate dissolved in acetone is mixed with \ba1/500\be part of its weight of phosphoric acid diluted with acetone.  Other cellulose acetate solvents or plasticizers may be present.  The ingredients are mixed thoroughly to form a fluid mass which is filtered if desired.  Non-solvents such as benzene, or alcohol, and higher boiling point solvents such as amyl alcohol, amyl acetate, or butyl acetate may be present.  It is preferred to employ \ba1/20\be to \ba1/2\be parts of phosphoric acid for every 100 parts of cellulose acetate.ALSO:Cellulose acetate is mixed with phosphoric acid in the presence of a solvent or mixture of miscible solvents to form solutions from which practically non-inflammable films may be obtained.  The solutions may also be used as lacquers and varnishes and for making other plastic bodies. Any of the phosphoric acids may be used such as ortho-, pyro-, meta-, or hypo-phosphoric acid.  In an example, cellulose acetate dissolved in acetone is mixed with 1/500 part of its weight of phosphoric acid diluted with acetone.  Other cellulose acetate solvents, or plasticizers, may be present.  The ingredients are mixed thoroughly to form a fluid mass which is filtered if desired.  For making lacquers, the proportion of solvent is increased and non-solvents such as benzene or alcohol may be added.  The volatile solvent may be mixed with solvents of higher boiling point such as amyl alcohol, amyl acetate, and butyl acetate.  It is preferred to employ 1/20 to 1/2 parts of phosphoric acid for every 100 parts of cellulose acetate.  Photographic and other films made from these compositions are flexible, smooth, transparent and resistant to flame, the latter property increasing with time.ALSO:Cellulose acetate is mixed with phosphoric acid in the presence of a solvent or mixture of solvents to form practically non-inflammable films and other plastic bodies.

The stop 16 may be in the form of balls retained in radial holes 17 in the part 1 and pressed into the path of the driving piston 4 by the sleeve portion 19 of the part 9; alternatively the stop 16 may be in the form of a split ring having a rear conical portion. When axial adjustment is to be made to vary the power a locking ring 21 operating in a groove 23 is pulled back against the action of a spring 24 to disengage projections from recesses 27 in the end face of the part 9 and permit the two parts to be screwed relatively to each other. A safety bore 20 prevents operation should the parts be unscrewed too far. Indicia 25 may be read through a window 26. To remove the driving piston 4, the parts 1 and 9 are unscrewed and the driving piston allowed to drop out with the shoulder 28 of the driving piston pushing aside the balls 16.

Abstract: 864,078. Heating plastic yarn electrically. KLINGER MANUFACTURING CO. Ltd., GILCHRIST, R. S., and MATTINGLY, D. A. E. Dec. 4, 1959 [Nov. 25, 1958], No. 37958/58. Class 39(3). [Also in Group IX] In apparatus for heat-treating thermoplastic or thermosetting yarns, e.g. setting yarn during a false-twist crimping process, such as described in Specifications 788,526 and 788,527, the heat responsive element of the thermostat which controls the fluid-heating means is located in thermal contact with at least one curved, metal tongue over and in contact with which the yarn is drawn. As shown, element 22, comprising an electrical resistance wire (the resistance of which varies with temperature change) wound on and disposed between mica sheets, is secured to the underside of a tongue 10: the wire is connected in a potentiometer circuit 23 whereby the current supply to heater elements 14, 18 is controlled to maintain tongues 10 at constant temperature. A thermocouple may replace element 22. The rotor of the pump which circulates heating fluid is driven by an electric motor 24 through a shaft 25 coupled to a spindle 26 through a universal joint 27. The spindle 26 is splined into a socket in an element 28 so that variations in the effective length of shaft 25 due to differential expansion of the pipe 20 and shaft 25 do not stress the motor bearings.

Title: Improvements in or relating to polyurethanes
Inventor: SIMCOCK RONALD ARTHUR
IPC: C08G18/48
Filed: 1961-11-03
Abstract: A modification of the process of the parent Specification comprises forming the polyurethane as a reaction product of (a) an organic polyisocyanate or polyisothiocyanate with (b) a polyether reactant which comprises a polyol having an average molecular weight of at least 4,000 and formed by reacting (1) a condensation product of an alkylene oxide reactant and an organic compound having at least three active hydrogen atoms in the molecule with (2) at least 1% but less than 10% by weight (of the alkylene oxide content of the condensation product) of ethylene oxide and effecting foam formation with the aid of an organic foaming agent which is present in the reaction mixture in which the polyurethane is formed.  The invention is particularly applicable to the preparation of foams by the one-shot technique. Suitable foaming agents are halohydrocarbons, aliphatic hydrocarbons and ethers. The foaming agent can be a gaseous organic compound i.e. a gas at 0 DEG C. and normal pressure or a volatile organic liquid of boiling point up to 75 DEG C. Halogenated hydrocarbons, aliphatic hydrocarbons and ethers are referred to.  Preferred reactants are (a) a toluene diisocyanate or a diphenyl methane diisocyanate and (b) a polyol obtained by reacting (1) a condensation product of 1, 2-propylene oxide and an organic compound having at least 3 hydroxy groups in the molecule, preferably glycerol and having a molecular weight between 4,000 and 8,000, e.g. between 4,800 and 5,200 with (2) preferably between 2 and 5% and advantageously about 3% of ethylene oxide (by weight of the propylene oxide content of the condensation product). Low density foams result when the reaction mixture contains a small proportion of water (e.g. 2.5 to 4% of the weight of polyol). Glycol can also be used as cross-linking agent.  In Example (1) the polyol is a reaction product of glycerol successively with propylene oxide and ethylene oxide.  This is converted to foam by the one shot process by reaction with toluene-2,4-and 2,6-diisocyanates, water, triethylene diamine, stannous octoate, silicone and monofluorotrichloromethane. In a comparison example the polyol used is a glycerol/propylene oxide condensate of average molecular weight about 3,000. Specification 901,362 also is referred to.
