Abstract: 374,068. Roads; walls ; foundations &c. WALKER, J. H., 21, Shooters Hill Road, Blackheath, London. Feb. 24, 1931, No. 5808. [Classes 20 (iv) and 107.] A method of making roads, areas, walls, foundations or other structures of concrete or like material which shrinks in setting, hardening, or solidifying consists in forming at least one layer of the concrete or the like and embedding therein,.whilst in an unset state, a series of separate solid inserts of small volume relatively to their over-all dimensions arranged (for example, in spaced relationship with one another) to ensure the production, as the material sets and hardens, of relatively minute cracks or lines of weakness which subdivide the structure at relatively close intervals and avoid the necessity for the usual expansion joints. The inserts may take the form of strip members 6 of sinuous shape arranged as shown in Fig. 3, or of hexagonal hoops 3 arranged as shown in Fig. 1 in the form of a discontinuous honeycomb. The strips 6 or hoops 3 are disposed on an under layer 2 of concrete while the latter is still unset and a further layer 4 of concrete is then applied so that lines of weakness develop as shown at 5. For re-surfacing an existing road, a series of rings 7, Fig. 5, are arranged on the road and a layer 9 of concrete applied. The inserts may also be in the form of flat steel or other bars arranged to constitute discontinuous squares, or pairs of such bars, arranged in the form of crosses, may be disposed in rows in the concrete layer. Projections, twists, &c. may be provided on the inserts for anchoring purposes. The inserts may be formed of metal, cardboard, &c. For walls, a series of inserts 10 of sinuous form as shown in Fig. 7 are suspended in vertical position between the shuttering while the concrete is being placed in position so as to produce cracks along substantially vertical lines at distances of from 3 feet to 4 feet apart. Alternatively, the wall may be cast in situ in successive courses between shuttering which is increased in height as the wall is being cast, and a row of hoops is supported between the shuttering of each course so as to be embedded in the wall material. The inserts for walls may also take the form of steel coils. Suitable dimensions and spacing for the inserts in connection with roads and walls of different thicknesses are given. Specifications 181,930, [Class 20 (iv), Floors &c.], and 351,525 are referred to. The Provisional Specification describes also the formation of the inserts as pre-moulded blocks of circular, square, hexagonal, ring, or other shape and of concrete.

Title: 2-acylamino-1-aryl-propane-1,3-diols
Filed: 1952-03-11
Abstract: 2 - Acylamino - 1 - arylpropane-1 : 3 - diols of the general formula <FORM:0719103/IV (b)/1> (wherein R represents an aryl radical substituted by at least one nitro group and R1 represents an alkyl or aryl radical, which may be substituted) are manufactured by selective reduction, with lithium aluminium hydride, of the carboxylic ester group of an oxazoline of the general formula <FORM:0719103/IV (b)/2> (wherein R11 represents an alkyl radical), by introducing an anhydrous ether solution of lithium aluminium hydride in a practically stoichiometric amount into a solution of the oxazoline while maintaining the temperature around 0 DEG  C. and stirring thoroughly, followed by acid hydrolysis of the reduction product to decompose the organo-alumino-lithic complex and open the oxazoline ring.  The stoichiometric amount of lithium aluminium hydride is 0.5 mol. per mol. of oxazoline when R1 is alkyl and 0.75 mol. when R1 is aryl, when loss of hydrogen occurs. The hydrolysis may be effected in a single step using a weak acid, or in two stages using first an anhydrous strong acid to produce a 4-hydroxymethyloxazoline salt which is then further hydrolysed with an aqueous solution of sodium acetate.  In examples: (1) a solution of trans-2-phenyl-5-p-nitrophenyl-4-carbethoxyoxazoline in ether is stirred at 0 DEG  C. while an ethereal solution of lithium aluminium hydride is poured in, and the product is hydrolysed to DL-threo-2-benzamido-1-p-nitrophenylpropane-1 : 3-diol by either (a) passing in hydrogen chloride, collecting the precipitated trans - 2 - phenyl - 5 - p - nitrophenyl - 4 - hydroxymethyloxazoline hydrochloride and heating it with sodium acetate solution, or (b) adding aqueous acetic acid and allowing the mixture to stand; (2) a solution of trans-2-methyl - 5 - p - nitrophenyl - 4 - carbethoxyoxazoline in ether and benzene is treated as in 1 (b) to produce DL-threo-2-acetamido-1-p-nitrophenylpropane - 1 : 3 - diol; (3) a solution of trans - 2 - dichloromethyl - 5 - p - nitrophenyl-4-carbethoxyoxazoline in ether and tetrahydrofuran is treated with lithium aluminium hydride as in (1) and the product hydrolysed with dilute aqueous methanolic formic acid to DL-threo-2-dichloroacetamido-1 - p - nitrophenylpropane - 1 : 3 - diol; (4) the corresponding L-trans-oxazoline similarly yields chloramphenicol.  Trans - 2 - phenyl - 5 - p - nitrophenyl - 4 - carbethoxyoxazoline is obtainable by condensing ethyl benzimidate with the hydrochloride of ethyl threo-p-nitrophenylserinate, or the hydrochloride of ethyl benzimidate with ethyl threo-p-nitrophenylserinate.  Trans-2-methyl- and trans- and L-trans-2-dichloromethyl - 5 - p - nitrophenyl - 4 - carbethoxyoxazolines are obtainable in an analogous manner or by nitration of the corresponding 5-phenyl compounds.

A switch for regulating the heat in e.g. an iron has auxiliary contacts mounted on a movable contact arm and on a thermal element engageable therewith, in order to indicate whether the iron has reached a preset temperature. The temperature of an iron is preset by adjusting a screw 26 and thus altering the spacing of control contacts 20, 21 which can be moved apart by a stud 31 on a bimetal strip 12. When the preset temperature has been reached, and the stud 31 is about to open the control contacts 20, 21, a slot 47 in an auxiliary contact arm 40 pivoted on the thermal element 12 coincides with the extremity of the fixed contact arm 11, thus allowing a spring 42 to close indicator contacts 41, 45. The slot 47 is so dimensioned as to accommodate the normal control fluctuations of the contact arm 11 and the indicator contacts 41, 45 thus remain closed whilst the preset temperature is being maintained. If the preset operating temperature is raised or lowered, the consequent movement of the contact arm 11 opens the indicator contacts 41, 45 until the new temperature has been attained. The main contact arms 10, 11 are each associated with an annular terminal member 19.
