Title: Process for the production of amides of alginic acid
IPC: B01J13/00
Filed: 1955-03-25
Abstract: Alginic acid amides are made by reacting alginic esters with one or more compounds HNR1R2, where R1 and R2 are hydrogen or organic residues, e.g. hydrocarbon radicals which may be substituted; the ammonia or amine is used in amount at least 0.5 and preferably 1.5-20 times the weight of alginic ester and the water content of the reaction mixture is not more than 50 per cent by weight of the dry ester.  The reaction temperature may be -10 DEG  to +50 DEG  C., preferably -5 DEG  to +40 DEG  C.  The products form gels on cooling their aqueous solutions containing 0.4-10 per cent of amide by weight.  The esters used may be those of mono- or poly-valent aliphatic alcohols of 1-3 carbon atoms, especially those obtained by esterifying alginic acid with diazomethane or alkylene oxides until at least 40 per cent and preferably 60-100 per cent of the carboxylic groups have reacted. The water content of the esters is preferably reduced below 50 per cent by washing with water-soluble organic liquids.  Some of the ester groups are probably hydrolysed to carboxylic acid salts at the same time as the others are converted to amide groups, and also some ester groups may remain unconverted.  In the examples: (1) alginic acid is esterified with ethylene oxide and the product reacted with ammonia, (2) alginic acid is treated with diazomethane to give a product containing methyl as well as ester groups and the latter reacted with ammonia; (3) the glycol ester of alginic acid is treated with ethanolamine, glycine, glycylglycine, dodecylamine, ethylene diamine and urea to give the corresponding amides, the last two being crosslinked.  In general the groups R1 and R2 may be hydrogen or aliphatic, cycloaliphatic or aromatic residues and may contain other atoms, e.g. in the form of hydroxyl, carboxylic acid, carboxylic amide or sulphonic acid groups.  Suitable amines other than the above are methylamine, ethylamine, propylamine, propanolamine, octylamine, octadecylamine, cyclohexylamine, amino-sugars, aniline, naphthylamine, benzylamine, anthranilic acid, sulphanilic acid, taurine, hexamethylenediamine and phenylenediamine.

Filed: 1927-03-30
Abstract: 269,512. Schirp, P. April 15, 1926, [Convention date]. Air, controlling circulation of.-Apparatus for drying textiles in two stages by a current of hot air which may be circulated continuously consists of adjacent drying chambers a, b which communicate through ceiling openings f<1>, f<2> with a steam-heated chamber g and through floor openings d<1>, d<2> and valved-chambers r<1>, r<2> either with a steam-heated chamber i or ducts p, q. The ducts communicate through a duct u, disposed within a chamber n at the rear of the drying chambers, with the suction side of a fan v, the pressure side 'of which communicates with an exhaust flue w having a damper-controlled bypass x to the chamber n. The front end of the heated chamber i is open to the atmosphere, while the rear end communicates with the chamber n. As shown in the drawings, in which the chamber b is assumed to be charged with wet material while the chamber a contains material which is partially dry, air is drawn by the fan from the atmosphere and the chamber n through the heated chamber i, upwardly and downwardly through the chambers a, b respectively, and through the ducts q, u, and is discharged to the flue w, any desired part of the air being by-passed to the chamber n for recirculation. When the material in the chamber a has been completely dried, the valves are displaced to the dotted line positions shown in Fig. 1, and a fresh charge is placed in the chamber a. The air is then circulated upwardly through the chamber b and downwardly through the chamber a. The valves are interconnected and may be connected to means for locking and unlocking the doors of the chambers.

Title: Improvements in and relating to Heel Building Machines.
Inventor: POCHIN FRANK HOWARD
IPC: A43D83/00
Filed: 1916-06-27
Abstract: 109,064. Pochin, F. H., Pochin, H. S., Clark, H., and Gradwell, C. June 27, 1916. Heels, machines for. - Heel - building machines of the type in which lifts are automatically collected from a series of hoppers and assembled in moulds, are provided with means for supporting each lift prior to its being deposited in the mould, and with an improved safety device for throwing the driving-clutch of the machine out of gear when an obstruction occurs. The invention is described as applied to the machine described in Specification 6740/15, in which a series of moulds 9, Fig. 2, connected by arms c to a ratchet plate C are moved beneath a ring of adjustablysupported lift hoppers M, each mould carrying a lift-collecting finger E. According to the present invention, the linger E pushes each lift into a spring holder 18, Figs. 1 and 2, extending downwards, so as to be substantially flush with the bottom of the hopper M, from a plate 17 resting on a plunger 16, the rod 14 of which is pivotally connected by a link 15 to one end of a rocking- lever 13. The bottom of each hopper may be provided with springs 20 which are extended and bent upwards at their free ends to ensure that the lifts will be pressed against the bottom face of the plunger 16 as the mould is moved from beneath the hopper; the hopper may be formed with an extension, along the bottom face of which the lift moves. The mechanism for intermittently moving the moulds is such that they stop when the lift is transferred to the holder 18, whereupon the lever 13 is rocked, causing the holder and plunger 16 to move downwards until the holder is arrested, whereupon the plunger continues its movement and forces the lift into the mould. The lever 13 is actuated through a spring plunger 23 from a cam-actuated table 21, to which it may be connected by a link 24, and the lower ends 23, 23<a> of successive plungers may be arranged in different planes. The levers G, J, Figs. 7 and 8, which actuate the rachet plate C carrying the moulds, are connected by spring-pressed spherical latches L, and when an obstruction occurs, these latches yield to release the rod J, and a slight further movement of the lever G then causes a lug 31 of a spring-pressed bolt 30 to ride off the rod J, whereupon the bolt engages a segmental rack 32 supported on a shaft 33. Continued movement of the lever G actuates the rack and shaft to depress a rod 35. the lower end of which depresses a lug 36 on the rear end of the treadle lever, raises the treadle, and disconnects the driving-clutch.

Abstract: 493,068. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. March 31, 1937, No. 9226. [Class 40 (iv)] A bidirectional group selector which upon release resumes its rotary movement to bring the wipers clear of the banks is provided with normal post springs which operate on a particular level and connect up an auxiliary magnet which allows the wipers to drop back. At the same time a wiper-switching relay is operated. The vertical magnet VM responds to the incoming digit in the usual manner and relay H energizes at the first vertical step. On the relapse of dialling relay C, the rotary magnet RM operates in a self-interrupting circuit as long as H is maintained by busy ground over test wiper P1. When an idle outlet or the 11th position is reached, H falls back and connects up C again, whereupon H reoperates to switch through to the wipers. The 11th position is wired back to line relay A over which a busy signal is sent. If, however, the selector is set to a level on which springs NP are operated, H fails to hold after the relapse of C, so that relay DA energizes, locks and switches over the wipers, while magnet ZM energizes and restores the wipers to normal. Dialling relay C reoperates in readiness for a second digit. Any further operation of springs NP is ineffective since DA provides an alternative circuit for Hand RM. Upon release, H and C fall back and the rotary magnet RM advances the wipers clear of the banks, whereupon they drop and return to normal. Specification 391,151 is referred to.

Title: Improvements in or relating to the treatment of edible oils
Inventor: ROYLANCE ALAN
IPC: C11B3/10
Filed: 1957-03-21
Abstract: Edible glyceride oils are refined by a process in which a solution of the oil in a nonpolar solvent, such as light petroleum, hexane, or cyclohexane, is brought into contact with activated alumina, after which the solvent is removed, the residual oil subjected to steam deodorization, and an antioxidant added.  The alumina is suitably obtained by activating gibbsite or bayerite by roasting at 350-900 DEG C. for 5 hours or more, and the solution of oil, usually a 5-50% w/v solution, is passed down a column of the alumina amounting to 5-500% by weight of the oil. If preferred, however, the alumina may merely be agitated with the oil.  The column is then generally washed with pure solvent to recover occluded oil and the eluates combined, after which the solvent is removed by distillation and the remaining oil steam-deodorized at 140-180 DEG C. at reduced pressure.  Suitable antioxidants which may then be added are the alkyl esters of hydroxybenzoic acids, especially propyl, octyl, and dodecyl gallates, tert. alkyl substitution product of hydroxyalkoxybenzenes, especially 2- or 3- tert. butyl-4-hydroxyanisole, and trialkyl substitution products of phenol, for example 2:6-ditert. butyl-4-methylphenol. The antioxidant may be added to the main bulk of the oil, generally in amounts of 0.001-0.1%, usually as a solution in either a small quantity of the oil or in propylene glycol.  It is also preferred that an equal amount of citric acid be added.  The oils to be treated should desirably have been alkali refined but not bleached, and include cottonseed, olive, groundnut, sesame, sunflower, safflower, soyabean, and rapeseed oils.  According to the Provisional Specification, the antioxidant may be added before or during the deodorization step, and the antioxidant may be nordihydroguaiaretic acid.
