Title: Improvements relating to footwear
IPC: A43B21/24
Filed: 1953-05-30
Abstract: 734,547. Shoe heels. STEIN, H. C. May 30, 1953. No. 15109/53. Class 17 (2). A multiple heel construction 34 comprises a fixed peripheral element 36 and a movable central element 38 spaced apart by a slit 40 passing through the heel sections and sole 14 to permit relative movement. Thus in walking the heel contacts the ground with the rear margins 48, 50 of each element so that the body weight is supported by the medial tuberile 30 of the oscalcis 18 at 50 and by the postero-inferior surface 28 engaging the upper edge 54 of the element 36 and the heel can then carry out its natural rolling movement. As shown, the slit 40 terminates short of the forward edge 42 of the heel forming a hinge part 44, but in a modification the slits are extended forward so that the hinge is formed with the sole 14. In another modification, the positions and shape of the slits are varied and more than one slit may be provided to form two or more inner heel elements while in one example the slit is circular forming a detached inner element. In all cases flexible resilient material may be inserted in the slit to increase the watertightness of the heel.

Title: Improvements in synthesis of pregnenolone and its esters and intermediates
IPC: C07J5/00
Filed: 1950-06-16
Abstract: Pregnenolone and its esters and intermediates therefor are manufactured by any one of the following steps, or a combination thereof or of the first three: (a) heating a 3-acyloxybisnor-5-cholen-22-al with an enol esterifying agent to form a 22-enol ester; (b) treating the product of (a) with ozone to ozonize the 20 : 22 double hond without removing the enol ester grouping; (c) subjecting the product of (b) to decomposition (preferably under reductive condictions) to form a pregnenolone ester; and (d) hydrollysing this ester.  Step (a) may be effected at about 60-150 DEG  C., using an acid halide or preferably a mixture of a carboxylic acid anhydride and an alkali metal salt of the corresponding acid, and step (b) at a temperature below about 30 DEG C. (preferably between about -30 DEG  and +10 DEG  C.), advantageously in a solvent (e.g. chloroform, carbon tetrachloride, ether-chloroform mixtures, methylene chloride, glacial acetic acid or methanol). Step (c) may be effected by subjecting the ozonide to steam distillation or by adding it to boiling acetic or propionic anhydride, to liquid ammonia, to a concentrated solution of potassium bisulphite, to a dilute solution of sodium bisulphite, to a mixture of powdered zinc and water, or preferably to a mixture of acetic acid and a metal (especially a metal above hydrogen in the electromotive series).  If desired, the 5 : 6 double bond may be protected before step (b) (e.g. by addition of halogen, preferably bromine, or formation of an i-ester or i-ether), and reintroduced before, after or simultaneously with step (c).  In examples: (1) 3-acetoxybisnor-5-cholene-22-al is refluxed with acetic acid and anhydrous sodium acetate, the resulting 3 : 22-diacetoxybisnor - 5 : 20(22) - choladiene is isolated and dissolved in chloroform, and treated with bromine and then with ozone, and the product is decomposed with zinc and glacial acetic acid, yielding pregnenolone acetate; (2) the process of (1) is carried out without isolating the enol-acetate, and omitting the bromination.  Other acyl radicals which may be present in the 3-position in the starting materials (and in the pregnenolone esters) or introduced into the 22-position are formyl, propionyl, butyryl, valeryl, isovaleryl, hexanoyl, heptanoyl, octanoyl, cyclohexanoyl, benzoyl, toluyl, naphthoyl, succinyl, glutaryl, adipyl, phthalyl, maleyl, methoxyacetyl, chloracetyl and chlorobutyryl.  3 - Acyloxybisnor - 5 - cholen - 22 - als are obtainable from stigmasterol esters by selective ozonization of the 20 : 23 bond in the presence of a tertiary amine.  In an example, 5 : 6-dibromostigmasterol acetate is treated with ozone in chloroform in the presence of pyridine, and the product is treated with zinc and acetic acid to form 3-acetoxybisnor-5-cholen-22-al.  The butyroxy, formyloxy, heptoyloxy and benzoyloxy compounds may be similarly prepared.

Title: Improvements in hydraulic distant-control apparatus
IPC: F15B9/16
Filed: 1924-06-26
Abstract: 229,995. Schneider et Cie. Feb. 25, 1924, [Convention date]. Addition to 218,993. Mountings.-Relates to the hydraulic distant-control apparatus claimed in the parent Specification, in which one or more motors M<1>, M<2>, M<3> receive the same volume of liquid controlled by a valve D at the central station, so that the receiving motors M<2>, M<3> at the gun station rotate synchronously with the motor M<1> at the central station which moves the sight, the receiving motors being furthermore fitted with compensating pumps C<2>, C' or differential gearing for the purpose of imposing small corrections on their movements. According to the present invention, which is concerned with the arrangement claimed in claim 7 of the parent Specification, the motors M<1>, M<2>, M<3> are fed separately by constant-speed electric motors E'. E<2>, E<3> respectively acting up variable-delivery pumps P<1>, P<2>, P<3>, the electric motors being synchronized and the devices p', p<2>, p<3> for varying the delivery of the pumps being simultaneously moved by equal amounts. In the form shown, the distributorvalve D is operated on the one hand by the screw N engaging the nut G, and on the other hand by the device p', which, through the rack F, rotates the nut G to close the valve. The valve operates through a press C on the presses x, y, z, connected to the presses p', p<2>, p<3> which vary the delivery of the pumps P<1>, P<2>, P<3> by equal amounts. The position of the crank N therefore determines the speed of the motors M<1>, M<2>, M<3>. The compensating pumps C<2>, C<3> are connected to the presses p<2>, p<3>. In a modification, the presses x, y, z are replaced by rotary pumps and local pumps driven from the motors M<1>, M<2>, M<3> act upon the receiving presses p<1>, p<2>, p<3> to oppose the action of the pumps at the central station. In this construction, the nut G is so driven that the speed of the motors M<1>, M<2>, M<3> is proportional to the speed of rotation of the hand-crank. In a further modification, the connection between the central station and the receiving station is effected by electric transmission acting through an hydraulic servomotor upon the devices for varying the pump deliveries. The cocks I, J permit of a change of sighting station. Specification 224,859 is referred to.

Title: Improvements in or relating to the manufacture of foamed polyurethane materials
Inventor: BURROWS HAROLD GEORGE
IPC: C08J9/00
Filed: 1963-04-19
Abstract: Foamed polyurethanes may be manufactured by the reaction of an organic polyisocyanate and a predominantly secondary hydroxyl ended polymer containing at least two isocyanate reactive groups per molecule under such conditions that a foam-forming gas is generated and in the presence of a polysiloxane containing at least one organic radical of the general formula <FORM:1077664/C3/1> attached directly to a silicon atom, wherein R represents hydrogen, a hydrocarbon radical, a substituted hydrocarbon radical or a hydrocarbon radical in which the hydrocarbon chain is interrupted by one or more hetero atoms. The preferred polyisocyanate is an 80 : 20 mixture of toluene 2:4- and 2:6-diisocyanates, the preferred hydroxyl ended polymer is a polyoxypropylene triol obtained by the reaction of propylene oxide with glycerol, and water is used as the foam generating agent.  In the examples the radical R is methyl, heptyl, octyl, t-butyl and cyclohexyl.  The polysiloxanes containing the grouping <FORM:1077664/C3/2> may be prepared by (i) reaction of an organic carboxylic acid with a polysiloxane containing silicon bonded hydrogen in the presence of a catalyst such as platinum on carbon, chloroplatinic acid which may be hydrated and addition complexes of platinous salts and olefines such as cyclohexane platinous chloride; (ii) acid interchange on polysiloxanes already containing the O-CO-R radical in the presence of a catalyst such as dimethyl sulphate and (iii) reaction of a polysiloxane containing silicon bonded hydrogen with an unsaturated alkyl ester of a carboxylic acid. Examples describe the reaction of <FORM:1077664/C3/3> wherein a and b have the following values, with (1) a=12, b=6; allyl acetate: (2) a=15, b=3; allyl acetate: (3) a=12, b=6; acid interchange of the product from (1) with 2-ethylhexoic acid: (4) as (3) but using nonanoic acid: (5) a=9, b=9; isopropenyl acetate: (6) a=9, b=9; trimethyl acetic acid: (7) a=12, b=6; cyclohexanoic acid: (8) a=9, b=9; isopropenyl acetate and styrene and (9) a=9, b=9; acetic acid and methyl methacrylate.

Title: Production of coloured photographic images
IPC: G03C5/40
Filed: 1941-12-05
Abstract: 553,751. Photographic toned images. TULL. A. G. Dec. 5; 1941, No. 15703. [Class 98 (ii)] A coloured photographic image is produced in an exposed silver halide emulsion layer containing a silver or silver salt image by treating the layer with a solution produced by dissolving a stabilized diazotized aromatic amine in solid form in water and including also a silver oxidizing reagent in the case of treatment of a silver image, to produce a silver diazotate and applying a solution of a coupling reagent to form a dye image. The silver salt image may be produced by bleaching a developed silver image after fixation, or may be a residual silver halide image remaining after development of a silver image (with or without removal of the developed silver), or may be a complex silver salt image produced by treatment of a residual silver halide image with a solution of thiourea or thiosinamine which may contain a salt to produce a complex image having an acid radical other than the original halide. The stabilized diazotized amine may be " Brentamine " (Registered Trade Mark), Fast Blue B Salt (stabilized diazotized diapipidine) " Brentamine " Fast Orange G Salt (stabilized diazotized m-chloraniline), Brentamine Fast Orange GC (similar), Brentamine Fast Reds 2G Salt (stabilized diazotized p-nitraniline), and Brentamine Fast Yellow G Salt (stabilized diazotied o-chloraniline). The coupling may be effected in neutral, alkaline, or acid solution. A fixed silver image may be treated with a solution containing cupric sulphate, potassium citrate, potassium ferricyanide, and Brentamine Fast Orange GC salt. After washing, the material is treated in a bath containing " Brenthol " (Registered Trade Mark) AT, borax, and hypo to give a light red image. The process may be applied to the production of the component pictures of a multicolour record. The process may be used to produce a coloured photographic image in one layer of a multilayer material, the other layers of which are procesed to colour by other methods. e.g. chemical or dye toning, by precipitation of an acid dye by a complex silver salt image produced by or in the presence of thiourea or by a combination of such methods. Specifications 363,616 and 387,197 are referred to. According to the Provisional Specification, a coloured image may be produced in another layer by formation of a dye lake image.

Title: Improvements in electric power supply systems
IPC: H02P9/00
Filed: 1924-06-30
Abstract: 240,526. Bean, M. B., and Price, W. I. N. June 30, 1924. Electric and electromechanical power transmission systems; supplying consuming devices.-In a power supply system, the load when heavy is taken by a prime mover and a generator of relatively high voltage and when light is automatically taken by a low voltage battery and motor and the high potential generator, the generator being then disconnected from the prime mover and tha motor being adapted to run as a generator to charge the battery when the prime mover is operating. The prime-mover P drives through a mangetic clutch C or free-wheel device a main, high-potential generator G<1> mechanically coupled to a low-potential generator G<2>, which is adapted to charge a battery B through a switch or automatic cut-out K. With a heavy load, the prime mover P drives the generator G<1> which energizes the solenoid H to close the switch S<2> and supply the load through the series coil X, the switch S' opening and protecting the battery B from the high-potential line. Closure of switch K allows G<2> to chaxge the battery. If P is shut down and no load exists on the line, the clutch C will be freed and the switch S<1> will close by gravity and connect the battery to the line. If now a load is put on the line, the series coil L will be energized to close switch S<4>, thus energizing the coil Z which closes the switch S<3> and generator G<2> with the coil Y in series now starts up as a motor and drives the generator G<1>. The coil H is thereby energized to open switch S<1> and de energize coil H but the coil X maintains the circuit of G<2> through the switch S<3>. If the load is removed, coil X is de-energized and opens S<3> thereby shutting down generators G<1>, G<2>. A double-current generator may be used instead of the individual generator G<1>, G<2>, or alternatively, the generator G<1> may be replaced by two generators, one of which is connected to the prime mover to deal with a heavy load and the other to G<2> to form a motor-generator set to take the light loads, the arrangement obviating the need for a clutch and requiring instead switchgear for disconnecting the idle generator.
