The compounds (a) possess narcosis-potentiating, adrenolytic, sedative, antimetic, antihistaminic, antipyretic and hypothermic properties in addition to their use as intermediates.  Alkali metal alkynes of the last general formula above are prepared by the action of an alkali metal (especially lithium, sodium or potassium) in liquid ammonia on the corresponding 3-(disubstituted - amino) - propynes - (1), certain of which are prepared by dropping an ethereal solution of propargyl chloride into an ethereal solution of 2 molecular proportions of N-methylpiperazine, piperidine, methyl-b -picolylamine, morpholine or diethylamine.

Title: Improvements in and relating to the preparation, treatment and application of resins
IPC: C08G75/16
Filed: 1942-04-01
Abstract: Resins containing hydroxyl groups made by heating in aqueous media an alkali or alkaline earth disulphide with a glycerol dichloro- or dibromo - hydrin alone or with ethylene di - chloride, b ,b 1-dichloroethyl sulphide or disulphide, b ,b -dichloroethyl sulphone or a ,a 1-dichloromethyl ether are condensed with acetic anhydride, benzoyl chloride, thionyl chloride or oxalic acid.  The resins may be washed before treatment either in the solid state or in solution, with a non-solvent, e.g. ethanol or benzene, or with a partial solvent, e.g. acetone or dioxan, to remove impurities.  After completion of the reaction, the product may be further heated in the resulting aqueous liquid.  The products may be soluble in ethyl or amyl acetate, acetone and aromatic and chlorinated hydrocarbons and are useful for coating compositions and vulcanizable adhesives.  In an example, the resin from a ,g -dichlorohydrin and sodium disulphide is stirred with excess of thionyl chloride, stirred and warmed.  The resulting solution is poured into water and the precipitate washed. The chlorine atoms in the product may be substituted by heating it with aqueous solutions of sodium polysulphide or ammonia to yield an insoluble, infusible resin. Films of this resin pigmented with zinc oxide or lead monoxide may be stoved at 100 DEG  C.  Specification 573,308 and U.S.A. Specification 2,026,875 are referred to.

Class 120(2) A textile spinning or twisting machine of the type including a snakelike belt extending the length of the machine frame and adapted to drive the spindles or flyers, a whorl associated therewith with each spindle or flyer and movable against the belt to transmit the drive to the associated spindle or flyer and a second whorl associated with each spindle or flyer and mounted adjacent to the face of the belt remote from the first whorl so as to be movable to disengage the belt from the associated spindle or flyer and to maintain the belt out of engagement therewith, has the first and second whorls mounted on a swing lever which is engageable by a bell crank lever acted upon by a further lever biased so as to urge the first whorl into engagement with the belt. In the arrangement shown twisting spindles 2 are each rotatable about a fixed axis on a rail 1 and 3 denotes a snake like belt which engages the spindles. Associated with each spindle is a swing lever 5 pivoted at 5<SP>1</SP> to rail 1 and carrying a first whorl 4 and a second whorl 6. A compression spring 12 is interposed between lever 5 and rail 1 and is adapted normally to urge lever 5 and whorl 4 to a position clear of belt 3 such that the belt is disengaged from the associated spindle 2. A bellcrank lever 7 pivoted at 7<SP>1</SP> is provided for holding the lever 5 in a position such that whorl 4 presses belt 3 against the whorl of spindle 2. This lever 7 is connected via a link 8 to a gravity influenced lever 10 which is held up in the operative position by a notch 10<SP>3</SP>, engaging with a further notch 11<SP>1</SP>, on a further lever 11. When the two notches are disengaged the lever 10 falls and removes the arm 7<SP>2</SP> of the lever 7 from the lever 5 thus permitting spring 12 to urge the whorl 6 to engage the belt 3 to disengage it from the whorl of spindle 2 and to engage a brake 9 with said whorl. Specifications 113,687, [Class 120(2)] and 575,878 are referred to.

Title: Improvements in or relating to the production of a plasticised nitrocellulose product
Inventor: HORN JAMES ARNOT
IPC: C08L1/18
Filed: 1956-02-15
Abstract: Granules comprising nitrocellulose and a plasticizer are made by forming a mixture of (1) drained particles of water-wet nitrocellulose containing at least 25 per cent of water; and (2) a plasticizer in an amount insufficient to convert the particles into a plastic mass, and subjecting the mixture, under such conditions that its volume is kept substantially constant, to such mechanical action that the particles of nitrocellulose are forced repeatedly into contact with one another and are at the same time subjected to shearing forces so as to effect the absorption of the plasticizer by the nitrocellulose particles, the loss of the original structure of the nitrocellulose particles and the forming of these particles into a compact mass, continuing the mechanical action to convert the compact mass into granules, and drying the granules under such conditions that they do not coalesce into a plastic mass.  The preferred water content of the nitrocellulose is 25-40 per cent. Specified plasticizers are tricresyl phosphate and dibutyl phthalate, 20-32 per cent of the latter by weight being preferred.  Examples are given.  Specifications 558,296, [Group IV], and 626,067, [Group II], are referred to.

Abstract: 726,224. Treating wood. DOW CORNING, Ltd. Feb. 20, 1953 [April 19, 1952], No. 4817/53. Class 140. Wood surfaces are treated with an organosiloxane containing units of the general formula R-SiO 4-n/2 , wherein n has an average value of 1.0 to 2.2 and R is an alkyl radical containing less than 5 carbon atoms, a monocyclic aryl radical or a hydrogen atom, said siloxane having not more than 55 per cent of the total R radicals as hydrogen atoms. The treated surface is rendered non-adherent to concrete. It is preferred that R should be methyl, ethyl, phenyl or hydrogen. Specified organosiloxanes which may be used include monophenylsiloxanes, phenylmethylsiloxanes, dimethylsiloxanes, dibutylsiloxanes, methyl hydrogen siloxanes, monomethylsiloxanes and ethylxylylsiloxanes. These may, if desired, be polymerized with compounds such as triphenylsilanols, phenyldimethylsilanols, methyldihydrosilanols, diethylhydrosilanols and silica. Alkyd resins may also be used as modifiers. Catalysts (such as the lead, iron, zinc and cobalt salts of acetic, hexoic and octoic acids) may also be added, generally in amounts of 0.05 to 4 per cent by weight of the metal constituent based on the siloxane. The siloxanes may be prepared by hydrolysis and condensation of silane mixtures wherein the component silanes have the general formula R n SiX 4-n , where R and n have the significance given above, and X is a hydrosable radical (see Group IV (b)). The compositions may be applied as solutions or emulsions by spraying, dipping or brushing. A deposit of between 0.10 and 0.40 g. per square foot is preferred, but greater or smaller amounts may be used if desired. In an example (2) a plywood form is brushed with a 3 per cent solution in xylene of a siloxane made by mixing 30 parts by weight of a tri-methylsiloxy end-blocked methylhydrogen-polysiloxane of 30 c.s. viscosity at 25‹ C. with 7.5 parts by weight of zinc octoate.
