Title: Improvements in or relating to method of increasing the high temperature strength ofheat-resisting alloys
Filed: 1946-06-24
Abstract: The high temperature creep strength of alloys containing 12-22 per cent of Cr, 10-30 per cent of Ni, 2-6 per cent of each of Mo, Nb and W, 0.20-0.60 per cent C and the remainder iron and unavoidable impurities is increased by subjecting them to a short heat treatment at 2150-2400 DEG F. followed by a rapid cooling and an ageing treatment at 1350-1550 DEG F. for 12 to 18 hours.  The high temperature treatment may be carried out after partial fabrication, e.g. rolling or forging, and the final fabrication, e.g. machining or grinding, before or after the ageing treatment. The rapid cooling is preferably quenching in water.  The alloy may also contain 5-30 per cent of Co.  Specification 583,212 is referred to.

Title: Flooring compositions
Inventor: HOGG WILFRID HENRY
IPC: C08K3/00
Filed: 1958-06-13
Abstract: A covering for floors and like surfaces comprises a polyurethane containing ether or thioether linkages mixed with an inert filler in an amount of from 50% to 90% by weight of the covering, and consisting of particles the majority of which have a size within the range of 1,676 mm. to 0,124 mm.  The floors can be covered by applying a mixture of a liquid polymeric ether or thioether containing in the molecule a plurality of groups having the formula -CXNH and at least two end groups having the formula -NCX, wherein X represents an oxygen atom or a sulphur atom, a cross-linking compound containing in the molecule at least two groups which are capable of reacting with -NCX groups and an inert filler in amount of 50% to 90% by weight of the composition and consisting of particles the majority of which have a size within the range 1,676 mm. to 0,124 mm. Preferably the cross-linking compound is dispersed in a volatile solvent such as methylene chloride or in an organic polyol such as a condensate of propylene oxide and glycerine and the solution is added to the polymeric ether or thioether and filler immediately prior to use. As polyols there can be used polyalkylene glycols, aryl or halogen-substituted polyglycols, polythioglycols, and polydiglycols, i.e. compounds of the formula H(OCH2CH2OCH2CH2OCH2)nOH and their sulphur analogoues where n is an integer having a value less than 50; also reaction products of propylene oxide with, for example, triethanolamine or triisopropanolamine; and propylene oxide and/or ethylene oxide reaction products of ethylene diamine, glycerol or trimethylol propane.  The NCX group-containing polymer can have added a retarder, such as benzoyl chloride acid butyl phosphate or p-nitrobenzene sulphenyl chloride.  Polyamines, amino-alcohols and carboxylic acids are specified as cross-linking agents.  Suitable fillers are silica sand, quartz, diatomite, tripoli, flint, clays, mica, pumice, pumicite, Fuller's earth, asbestos, carbon black, and coke, charcoal, with which may be mixed barytes, gypsum, anhydrite and chromium pigments and iron silicates.  In Example (1) 100 parts of a syrup, prepared by reacting toluene -2,4- and 2,6-diisocyanates with polypropylene glycol containing about 3% trimethylolpropane, is mixed with 700 parts of graded sand and quartz mixture, into which had been dispersed 11 parts of melted methylene-bis(o-chloroaniline). Other examples employ sand mixture on which has been dispersed (2) monoethanolamine; (3) pyridine and trimethylol propane.  In Example (6) the polymer is a reaction product of toluene-2,4-and 2,6-diisocyanates with a polypropylene glycol derivative of ethylene diamine.

Abstract: 147,472. Williams, G. A. Dec. 15,1914, [Convention date]. Capsules, applying.-Relates to a machine for capping bottles with closures of the type in which a lever attached to the cap is used to fasten the cap in the mouth of the bottle. In the machine shown in Fig. 2, the cap 10 is held in a chuck secured to the lower end of a rod 12 which can be moved upwards against the pressure of a spring 27. A casting 16 which is also secured to the lower end of the rod 12 carries an horizontal shaft provided with a finger 21 adapted to turnover the lever 11 of the cap when the shaft is rotated. A rack 24 secured to the frame of the machine causes rotation of the finger 21 through the medium of gears 22, 23, 23<1> when the rod 12 is moved upwards. In use, a cap is placed in the chuck, and a bottle 8 is placed in a table 4 which is raised bv means of a treadle. The mouth of the bottle enters the cap and then forces the cap, and therefore the rod 12 upwards. The finger 21 is thereby caused to rotate and turn over the lever 11, and the cap is clamped on the bottle.

A lug 11 is received pivotally in a socket 10 of the ball 4 and is shaped so as to be able to pivot only forwardly; a web 16 projecting from the lug 11 through a slot 17 in the socket 10 to be engaged by the spring 20. Any rearward or sideways deflection of the component 1 is accommodated by the ball and socket joint but when the component receives a force urging it forwards the joint 10, 11 takes the initial deflection before the ball and socket joint moves. The socket 5 is shown as being an integral part of a mounting member 6 inserted into an aperture in vehicle body 2 and a member 28 which tensions the spring 20 has stamped out fingers 33 to snap engage grooves 34 on the socket. In a modified construction (Figs. 6-8 not shown), the socket 5 is formed separately from the member 6 and these two components are urged together by a compression spring through the centre of which the spring 20 extends. In this construction the member 28 is interlocked with a further member carrying the compression spring and the further member snap engages the mounting member 6.

Abstract: A glycidyl ether of a polyhydric compound having an epoxy equivalency greater than 1 is cured by means of an N, N-dialkyl-1, 3-propane diamine.  The alkyl groups may be the same or different. Preferably each alkyl group contains less than 3 carbon atoms, but the alkyl groups may be propyl, butyl, isobutyl, amyl, 2-ethylhenyl or stearyl. Curing agents specifically mentioned are N-methyl-N-ethyl-1, 3-propane diamine; N-methyl-N-butyl-1, 3-propane diamine; N, N-diethyl-1, 3-propanediamine; N, N-dimethyl-1, 3-propanediamine. Methods of making suitable curing agents are described in Specification 521,831, [Group IV], and U.S.A. Specifications 2,429,876 and 2,436,368.  Curing temperatures may vary from 20-250 DEG C.  The glycidyl ethers employed may be prepared as described in Specifications 680,997 and 681,099.  Suitable glycidyl ethers are prepared from epichlorhydrin and 2, 2-bis (4-hydroxyphenyl) propane or glycerine.  To facilitate mixing with the curing agent the glycidyl ether may be heated or mixed with a solvent which may be a volatile one which escapes before or during curing, e.g. acetone, methyl ethyl ketone, methyl isobutyl ketone, isophorone, ethyl or butyl acetate, ethylene glycol monoacetate, the acetate of ethylene glycol monomethyl ether, the methyl, ethyl or butyl ether of ethylene or diethylene glycol, trichloropropane or chloroform.  These solvents may be diluted, e.g. with benzene, toluene, xylene or ethyl, isopropyl or n-butyl alcohol.  Solvents which remain in the cured products may also be used, e.g. diethyl or dibutyl phthalate, liquid mono-epoxy bodies, e.g. glycidyl allyl or phenyl ether, styrene oxide, 1, 2-hexylene oxide, or aceto-, propio-, adipo- or benzonitrile.  A glycidyl ether of a dihydric phenol may be fluidized with a liquid glycidyl ether of a polyhydric alcohol.  The compositions may include pigments, dyes, plasticizers, or compatible resins.  The adhesives and curing properties of compositions cured with varying amounts of amines and with different amines are compared in the examples.  Example 4, 5 describes adhesive compositions containing in addition to the glycidyl ether, polyvinyl acetate, allyl glycidyl ether and asbestos; Example 4 to Specification 705,098.
