Abstract: 463,462. Collars for personal wear. HENDRYCY, C. F. March 4, 1936,' No. 6608. Convention date, Jan. 23. [Class 141] A collar having front and back plies and a filler is provided between the two opposed longitudinal edges of the neckband with reinforcing pieces 20 of stiffening material secured by stitches to the adjacent plies. The reinforcing plies may be of any convenient shape, but in the modifications described are rectangular, and have short slits parallel to the longitudinal edges of the collar so that the margins 9 can be folded over to increase the rigidity of the reinforcement. In one form, the outer ply 17 of the neckband is cut away to expose a portion of the reinforcement in the form of a segment of a circle. The inner ply of the neckband is shown at 18. The reinforcement is secured by stitching 23 along the edges of the neckband and stitching 25 around the circular edge of the cut-away portion of the outer ply. In a second form of the invention the outer ply 17 is not cut away and the stitching 25 is unnecessary.

Title: Process for the production of high molecular weight calcium complex compounds
IPC: C08B37/06
Filed: 1957-02-28
Abstract: High molecular weight calcium complex compounds of polysulphuric esters derived from pectin are produced by reacting pectin in aqueous solution at pH 5-7 with hydrogen peroxide in a concentration of 1-5% and in an amount of 20-100% calculated on the dry weight of the pectin, until the desired degree of partial decomposition is attained, then precipitating the higher molecular weight parts of the decomposition products by the addition of water-soluble organic solvents, isolating and drying them and then converting them by means of chlorosulphonic acid in formamide or pyridine into acid polysulphuric acid esters, reacting the latter, after neutralization with a non-precipitating base in aqueous solution and while maintaining the reaction in the region of neutrality, with an ionizable calcium salt, and then, if desired, precipitating the calcium complex compound with a water-soluble organic solvent.  The reaction with hydrogen peroxide is advantageously performed in the presence of at least 1%, calculated on the total aqueous reaction solution, of an organic substance (or mixture of substances) at least soluble in this concentration in water as well as in diethyl ether and having pectin precipitating properties in higher concentrations in so far as these are attainable in water.  The formation of the calcium complex compound may be effected by reacting the sodium salt of the acid polysulphuric acid ester in aqueous solution in the region of neutrality with a pyrogen-free, water-soluble, ionizable calcium salt (e.g. calcium gluconate) in an amount containing at least half to about as many calcium ions as can be bound in complex linkage in the whole calcium complex.  The products are therapeutically useful as anticoagulants.

Title: An improved process for the catalytic dehydrogenation of hydrocarbons
IPC: C07C5/333
Filed: 1943-04-29
Abstract: <PICT:0582624/III/1> In the dehydrogenation of hydrocarbons by means of a finely divided catalyst the reactants while at temperature (e.g., 50-500 DEG F.) below the reaction temperature are mixed with a controlled amount of catalyst at a higher temperature (e.g., 1050-1400 DEG F.) to heat them to reaction temperature (e.g., 900-1150 DEG F.).  The reaction products are separated from the catalyst and the latter may be regenerated and used again.  Any excess of heat in the regenerated catalyst may be removed by cooling a part of it and recycling to the regenerator, and any deficiency may be made up by introducing a fuel into the regeneration zone.  In the illustrated apparatus the preheated feed in pipe 8 is mixed with hot catalyst supplied through pipe 9 from regenerator 51, and passed into reactor 13.  The reaction products after passing through a cyclone 22 are cooled and scrubbed with oil in a tower 25.  The scrubbing oil is recycled and undergoes heat exchange with the feed in cooler 4.  A portion of it is passed through a filter 38, and the catalyst so recovered is returned to the reactor by line 43.  Spent catalyst is continually withdrawn from the reactor through line 46, suspended in air and passed into regenerator 51.  The regenerated catalyst is returned to the reactor by line 9, but a portion may be passed through cooler 67 and returned to the regenerator.  Specifications 558,879 and 570,142 are referred to.

[Also in Divisions A3, B2, B6 and B8] A method of processing shoe soles comprises advancing a plurality of soles singly in succession whilst orientated approximately in the same direction in relation to their direction of advancement, firstly past a reducing station at which substance is removed from a face of each sole and afterwards past an adhesive applying device by which adhesive is applied to the reduced sole face. As shown, apparatus for carrying out the method comprises a magazine 10 for a supply of soles S which are fed into succession to splitting apparatus 11 from which they pass automatically in turn to conveying apparatus 12 so constructed as to invert each sole in turn as it passes forward, the soles then being delivered in turn to an adhesive applying device 13 equipped optionally with bending apparatus 14 acting on the soles immediately before they have adhesive applied to them. From the device 13, the soles pass automatically to stacking apparatus comprising a conveyer 15 and a transfer station 16 at which the soles are automatically transferred on to a holder 17 on which they can remain until the adhesive is allowed to dry. Adjustable means 19, 23, 26 are provided for locating the soles in registry with the magazine 10 with their longitudinal dimension positioned along the direction of feed. Soles are advanced singly toe end foremost from the magazine 10 to the apparatus 11 by means of a camoperated pusher plate 42 while a treadle lever 60 is released. The apparatus 11 comprises a matrix roller 28 having a sole-shaped recess pressed towards a co-operating roller 31, the rollers 28, 31 being driven in opposite directions from an electric motor 35 to feed a sole to a splitting knife 33 which removes substance from those parts of the sole which extend below the recess in the roller 28.

Abstract: 882,876. Thermal switches. RHEOSTATIC CO. Ltd. Feb. 11, 1960 [March 2, 1959], No. 7227/59. Class 38 (5). A resilient blade 5 carries a contact 3 for co-operation with a fixed contact 1 and a twin armature 4 acted on by a magnet 6. The resiliency of blade 5 tends to open contacts 3 and 1 whilst the arrangement is such that the resultant magnetic force on armature 4 always acts in opposition to the blade 5 and exceeds the force thereof to maintain the contacts normally closed. A thermally-sensitive liquidfilled element 14 is connected to a capsule 13 acting on the end of a lever 16 pivoted at 18. The other end of lever 16 acts on the blade 5 through a sliding stud 21 and at a temperature predetermined by adjustment of pivot 18 by a knob 18a the contacts 1, 3 are snapped open. The mechanical force due to capsule 13 then falls more rapidly than the magnetic force so that the contact 3 attains an equilibrium position and no back stop is necessary to fix the contact gap; thus the possibility of overstressing the blade 5 by undue adjustment of knob 18a is avoided. A screw 10 acts on a stiff spring 7 carrying magnet 6 and serves to adjust the switch differential. Specification 661,242 is referred to.
