Title: Improvements in or relating to preparation of finely divided cellulose ethers, esters and mixed ether-esters
IPC: C08B11/20
Filed: 1952-04-15
Abstract: Film-forming cellulose ethers, esters or mixed ester-ethers, alone or associated with plasticizers, are converted into powder form by forming a lacquer-in-water emulsion containing, in addition to water, the cellulose derivative and a water-immiscible volatile solvent therefor and for any plasticizer present (or a major proportion of such solvent and a minor proportion of a water-miscible solvent) and passing a stream of the emulsion into p  a vessel containing an agitated liquid which is a non-solvent for the cellulose derivative, is immiscible with the water-immiscible volatile solvent, and has a boiling-point at least equal to and preferably above that of the solvent at the pressure employed, the relative volumes of the stream of emulsion and of the non-solvent liquid, the temperature of the latter and the pressure in the vessel being such as to volatilize the solvent substantially completely from the lacquer droplets as the emulsion is added, leaving the cellulose derivative free from solvent and in the form of a finely-divided solid having a particle size not greater than 15 microns dispersed throughout the medium.  With an ethyl cellulose or cellulose acetate formulation the preferred solvent is a mixture of 80-95 parts by weight of methylene chloride and 20-5 parts of a lower aliphatic alcohol such as methanol, ethanol, propanol or butanol.  With a nitro-cellulose formulation the solvent preferably consists of 60-70 parts of methylene chloride and 40-30 parts of a lower aliphatic ester such as methyl or ethyl acetate.  Among the cellulose derivatives which may be used are cellulose propionate, butyrate, benzoate, stearate and crotonate, cellulose acetate propionate, acetate butyrate, acetate benzoate and acetate crotonate; benzyl cellulose and hydroxyethyl cellulose; ethyl hydroxyethyl cellulose acetate, ethyl cellulose acetate, ethyl cellulose crotonate, and benzyl cellulose acetate.  In an example an emulsion containing 12.5 parts cellulose acetate, 70 parts methylene chloride, 17.5 parts ethanol, 0.125 part sodium dioctyl sulphosuccinate, and 40 parts water is run at a rate of 10-15 volumes per minute into a vessel containing 1000 volumes of water at 85-90 DEG  C.  Over 95 per cent of the resulting particles of cellulose acetate dispersed in the aqueous medium are uniform spheroids about 5 microns in diameter. In other examples, slurries are similarly prepared using emulsions of ethyl cellulose, methylene chloride, ethanol or methanol and water; nitrocellulose, methylene chloride, ethyl or methyl acetate and water; and nitrocellulose preplasticized with dibutyl or dicyclohexyl phthalate, ethyl or methyl acetate and water, additional dicyclohexyl phthalate being in some examples present in the emulsion.

Title: Improvements in or relating to the provision of temporary protective coatings on shoe parts
IPC: A43D11/00
Filed: 1941-07-28
Abstract: 551,619. Coating surfaces; synthetic resin compositions. UNITED SHOE MACHINERY CORPORATION. July 28, 1941, No. 9542. Convention date, July 29, 1940. [Class 95] [Also in Group IV] A method of applying to a shoe part a temporary protective coating of a synthetic resinous material which may be readily removed when it has served its purpose, comprises providing a synthetic resinous material which is a thin liquid at an elevated temperature and becomes thicker at lower temperatures, causing a blast of gas to act upon the resinous material to form a heated spray, and directing the spray upon the shoe part, the said method being such that the particles of the spray are of a sticky character on formation, but as the spray travels from its point of formation to the shoe part the particles decrease in stickiness and upon deposition form a coating which adheres only lightly to the shoe part. Specified resinous coating compositions comprise:- (1) a vinyl acetal resin, diphenyl benzyl benzoate as plasticizer, acetone and ethyl alcohol: (2) a vinyl acetal resin, an A-stage phenol-formaldehyde resin, diphenyl benzyl benzoate and acetone, with or without petrolatum, zinc chloride, ammonium chloride and water : (4) a vinyl acetal resin, an A-stage phenol-formaldehyde resin, diphenyl benzyl benzoate, and calcium stearate as a heat stabilizer. An apparatus for carrying out the method may comprise a pivoted support 7 for a lasted shoe 100 which latter may be swung and turned in front of the heated spray gun 11.

Title: Electronic distributor
Inventor: FAULKNER ALFRED HUGHES
IPC: H04Q3/52
Filed: 1955-04-01
Abstract: 806,304. Automatic-exchange systems. AUTOMATIC ELECTRIC LABORATORIES Inc. April 1, 1955, No. 9602/55. Class 40 (4). In an allotter a number of individual resistor-rectifier gates are provided, each serving when open to connect the test wire of one of the circuits to be allotted to a common conductor in the allotter, the arrangement being such that all the gates except one are normally closed, the busy potential, if present on the test lead associated with the open gate, passing to the common conductor and operating means in the allotter which effects the closure of that gate and the opening of the next gate, whereby the circuits are tested in sequence until an idle one is found. The allotter described, which serves to allot an idle link circuit as in Specification 719,085, consists of a control circuit comprising tubes 110, 120 and a counting chain comprising tubes 130 to 190, there being one counting tube for each link circuit. Tube 110 constitutes a square wave oscillator, the left (L) triode of 120 delivering a sharp pulse from its cathode circuit to the counting chain for each oscillationof 110, and the right (R) triode of 120 preventing interference with busy link circuits during hunting. Normally, with the L triode of a counting tube, such as 130, non-conducting the neon lamp 137, is not fired, and any potential present on the test lead 130A, is shunted to ground by closed gate 166, 138. However, when triode L130 conducts, lamp 137 fires, thus opening that gate and gate 162, 138, and connecting the test leads 130A and mark lead 130B of the corresponding link circuit (No. 1) to the common control and mark leads 107 and 106, respectively. If the link circuit is busy positive potential on 130A is .extended via 107 to the grids of L110 and R120 to cause those triodes to conduct. Tube 122 is de-ionized and the mark lead 106 falls to ground potential. R110 is cut-off and the abrupt rise in its anode potential is applied via the short time-constant R-C circuit 117, 118 to the grid of L120 which repeats the pulse from its cathode circuit via capacitor 139 to the L cathodes of all the counting tubes. L130 which is conducting is cut-off by this pulse, 137 is doused, closing the gate of the tested busy link circuit No. 1, and the rise in anode potential of L130 is applied via 144 to the grid -of L140 which thereupon conducts. Tube 147 fires and circuit No. 2 is tested in the same manner. If circuit No. 2 is free (no potential on 140A) lead 107 returns to ground potential, R110 conducts and R120 ceases to conduct, whereupon 122 fires and applies positive potential to the common mark lead 106 and thence to mark lead 140B to cause connection to the free second circuit.

Title: Process for increasing the quantity and fulvo acid content of the humin fraction of low polymerization degree of compositions comprising particularly humins and fulvo acids as bioactive component
Inventor: VADASZ KRISZTIAN
IPC: C05F11/02
Filed: 1991-07-22
Abstract: Compsns. arrived at by alkaline treatment and aq. extraction of humic cpd. substrates are bioactive. Bioactivity is due to fractions of low degree of polymerisation of humic cpds. and to fulvic acids. The degree of polymerisation of large mol. wt. of humic cpds. may be reduced significantly by oxidative degradation, and as a result the concn. of hymatomelanic-acid. This cpd. has a most important role among humic cpds. in triggering bioactivity. Simultaneously humic acids tend to be transformed into fulvic acids. Thus the bioactivity of humic cpd. and fulvic acid compsns. is greatly improved by oxidative degradation. - Hydrogen peroxide or other peroxides may be used as oxidising agents. This process may be used with advantage in increasing the bioactivity even of previously microelements enriched cpds.
