Title: Wave guide
IPC: H01P1/28
Filed: 1947-03-03
Abstract: 627,092. High-frequency transmission lines. HAZELTINE CORPORATION. March 3, 1947, No. 6018. Convention date, March 27, 1946. [Class 40 (viii)] A high-frequency transmission line, comprising a number of conductive portions 10 and 11 defining a space for the propagation of guided electric waves, has its length determined by a short-circuited transmission line section 15 of length equal to an odd integral multiple of one-quarter of a wavelength at the operating frequency, this section including at least one conductive portion 17 adjacent to but spaced from one of the conductive members 11 of the main line and providing therewith an openended transmission line section containing a dielectric member 25 supporting the open end of the short-circuited section. Member 17 may be formed with a recess 24 to grip member 25. A similar arrangement of a dielectric support to that shown for a coaxial line may also be used in a wave-guide or for Lecher wires. The arrangement places member 25 in a region of low voltage gradient so that it can be made of relatively inexpensive materials whose high dielectric loss would normally render them unsuitable. The member 15 may be adjusted by an insulating member 27 operated by a screw 33.
Patent GB-816888-A (GB)
Title: Improvements in or relating to polyfunctional surface-active agents
Inventor: BOLLE JEAN
Filed: 1957-02-22
Abstract: A protein product, useful as a surface-active agent, comprising quaternary ammonium groups and salifiable carboxyl groups, is produced by reacting a degraded protein with a halogenated acid chloride and condensing the reaction product with a tertiary amine. The degraded protein containing liberated SH groups may first be condensed through a Schotten-Baumann process with strongly reactive halogenated acid chlorides to form thioester groups, and then the halogen still available in the degraded protein reacted with a tertiary amine to obtain a quaternary ammonium compound.  The protein degradation product may be obtained from vegetable proteins, e.g. gliadine, animal proteins, e.g. fibrin or gelatin, or fish proteins. Halogenated acid chlorides specified are chloroacetyl chloride, a -chloropropionyl-, a -chlorobutyryl-, a -chlorolauryl and a -chlorophenylacetyl-chloride, di- and tri-chloroacetyl chloride, chloroacetylamidobenzoyl- and chloromethylbenzoyl-chloride, and a -b -dichloropropionyl chloride.  The tertiary amine may be a straight-chain tertiary amine, e.g. octyldimethyl-, lauryldimethyl-, lauryldiethyl-, or myristyldimethyl-amine, or branched-chain tertiary amines, e.g. ethylhexyl dimethyl-, t-octyldimethyl-, or t-dodecyldimethylamine, hydroaromatic or arylaliphatic amines, e.g. dodecyldimethylaniline or dodecyldimethyl benzylamine, and tertiary amines containing other functional groups, e.g. dimethylaminoethanol esters or diamines of amides.

Abstract: The invention relates to a therapeutic polypeptide for increasing resistance to infections and stress and without substantial pyrogenic or antigenic action, recovered from yeast-cell wall material, being substantially free from polypeptides of molecular weight less than 1000, being heat stable at least up to 100 DEG C., being soluble in liquid phenol, in water and in aqueous bases, being precipitatable from aqueous solution by phosphotungstic acid and sulphosalicylic acid, showing a yellow-green fluorescence and containing the following amino acids in polypeptide form namely glutamic and aspartic acids, argimine, lysine, alanine serine, valine, leucine, isoleucine, glycine, phenylalanine histidine, proline, tyrosine and threobine, being substantially free from combined phosphorus exhibiting a positive anthrone and biuret reaction and having an antimitotic effect against He La and Chang cells.  Preferably the polypeptide is free from polypeptides having a molecular weight less than 8000.  It may be isolated from zymosan, a substantially protein-and carbohydrate-free water-insoluble yeast cell-wall product, by extraction with 90% aqueous phenol at 37 DEG C., followed by treatment of the extract with water-ether, separation of the water layer, addition of NH40H to solubilize any insolubles, treatment with ether to remove traces of phenol and freeze-drying. Alternatively, zymosan may be treated with NaOH for 24 hours, the supernatant separated and neutralized, concentrated and filtered. The solution was purified by fractionation or a Sephadex G50 column equilibrated with water-containing 0.3% cresol.  Further purification may be by dialysis and ultrafiltration.  The therapeutic polypeptide may be formulated into compositions for oral, parenteral, topical and rectal administration.

Title: Improvements in cellulose esters
IPC: C08B3/22
Filed: 1940-04-05
Abstract: 540,147. Cellulose esters ; artificial filaments &c. BRITISH CELANESE, Ltd. April 5, 1940, No. 6218. Convention date, April 6, 1939. [Class 2 (ii)] In the production of a cellulose ester of an organic carboxylic acid, there is added to the primary esterification solution, for the purpose of improving its stability, an organic acid having a dissociation constant of at least 1.55 x 10<SP>-3</SP>. The treated solution may be used for the production of filaments, foils, films, and other products. An acid anhydride may be used as esterifying agent and a catalyst such as sulphuric acid, zinc chloride, acid sulphates, or mixtures of sulphuric and phosphoric acids may be present during esterification. In addition to the organic acid, there may also be added to the primary*esterification solution water or other hydrolysing agent just sufficient to hydrolyse any excess of acid anhydride. The organic acid which is added may be monochloracetic, trichloracetic, or oxalic acid. Since the tendency towards gelation is reduced in the treated solutions, the proportion of catalyst employed in the esterification may be reduced, e.g. sulphuric acid in amount 0.5 per cent based on the weight of cellulose may be used. In an example, cellulose is acetylated with a mixture of acetic acid, acetic anhydride, and sulphuric acid, and at the end of the re-action sufficient water is added to hydrolyse excess anhydride. Oxalic acid in amount 5-10 per cent of the acetylation solution is added. The solution may then be stored for several months. It may be wet spun into filaments, foils, and the like. The process is applicable to the production of cellulose acetate, propionate, butyrate, and other cellulose esters and mixed esters.

Title: Prevention of coke deposits in fluid cokers used for the thermal cracking of heavy hydrocarbon oils
IPC: C10G9/32
Filed: 1956-03-05
Abstract: <PICT:0815992/III/1> In a process for the thermal cracking of heavy hydrocarbon oils by introducing the oil, through line 7, into a hot fluidized bed 2 of inert solid particles (e.g. coke), wherein a portion of the particles is continuously withdrawn from reactor, via standpipe 9, and the withdrawn particles are re-heated in an external heater (not shown) and then returned to the reactor by a stream of conveying gas such as steam, the deposition of coke in the part of the reactor above the fluidized bed is prevented or reduced by introducing the reheated particles and conveying gas, via conduit 10, into the reactor at a level slightly below the top L of the fluidized bed.  The cracked vapours are withdrawn from the top of the reactor via cyclone 3, wherein entrained particles are separated; the product vapours withdrawn from the cyclone are quenched, scrubbed to remove heavy ends, and then fractionated to recover gas oils and naphthas. Conduit 10 terminates in an upwardly-diverging conical member provided with a grid 13 located 3 inches below the top of the fluidized bed.  The reheated particles from conduit 10 are retained in the fluidized bed; but the conveying gas mixes with the cracked vapours rising from the bed, and prevents the condensation and subsequent polymerization and coking of the heaviest components of the vapours in the upper part of the reactor.  As a further aid to eliminating coke-deposition, it is advantageous to have substantial entrainment of particles in the vapours rising from the bed; and this effect is enhanced by reducing the diameter of the upper portion 14 of the reactor.  To increase the entrainment further, the particles separated from the vapours in cyclone 3 are supplied by line 4 to the terminal portion of conduit 10.  The entrainment may be controlled by regulating the amount of conveying gas admitted through line 10; extra gas above the amount normally required to convey the reheated particles may, if desired, be supplied through line 15.
