Patent GB-742362-A (GB)
Title: Improvements in or relating to process for recovery and purification of cyclodienes from cracked petroleum
Filed: 1952-10-17
Abstract: C5 and C6 cyclodienes are recovered from cracked naphtha by a process comprising fractionally separating the naphtha into a C4-C9 fraction and a C5-C12 fraction, removing C10-C12 hydrocarbons from the C5-C12 fraction by fractional distillation at temperatures from 240 DEG  to 410 DEG  F. to obtain a C5-C9 fraction, polymerizing the dienes by soaking the C5-C9 fraction at a temperature of from 150 DEG  to 240 DEG  F. and distilling off some of the unchanged C5-C9 hydrocarbons to obtain a concentrate of cyclodiene dimers and codimers containing 60-90 per cent of cyclodiene dimers and codimers, the remainder being other, mainly C7-C9, hydrocarbons, and recovering the C5 and C6 cyclodienes from the concentrate.  The initially obtained C4-C9 fraction may also be fractionated to obtain a C5-C9 fraction which may be soaked together with the main C5-C9 fraction.  The distillation of the C5-C12 fraction is preferably carried out at incipient depolymerization temperatures whereby dimers initially present in the cracked naphtha may be largely converted to monomers; the high boiling residue comprising unchanged dimers may be treated together with the dimer concentrate for recovery therefrom of the C5-C6 cyclodienes.  Preferably these are reovered by a two-stage depolymerization.  The first stage is operated under slight pressure, e.g. 2-20 p.s.i.g., to maintain the diene polymers in liquid phase at depolymerization temperatures of e.g. 380 DEG  to 410 DEG  F., the residual diene polymer liquid passing to the second zone operated under higher temperatures, e.g. 390 DEG  to 420 DEG  F.  The distillates from both zones, comprising C5 and C6 cyclodienes and some C7-C9 hydrocarbons, are passed together to a fractionating column from which the C5 and C6 dienes are taken overhead, the residue being recycled to the depolymerization stage.  The mixed C5 and C6 cyclodienes are then separated from one another by further fractionation.  Single stage depolymerization at above 380 DEG  F. is mentioned.  Suitable apparatus for a continuous process is described.

IPC: F04C2/12
Filed: 1959-07-30
Abstract: 903,814. Gear pumps and motors. VICKERSARMSTRONG (ENGINEERS) Ltd. Sept. 15, 1960 [July 30, 1959], No. 26189/59. Class 110 (2). In a gear pump or motor comprising a casing housing three gears or any even number of gears greater than three disposed in a closed chain, the middle gear of three gears or each alternate gear in the chain of gears is rotatable about a centre adjustable with respect to fixed centres about which the remaining gears rotate by control means to move the middle gear or each alternate gear into narrower mesh with one of its adjacent gears and into wider mesh with the other of its adjacent gears so as to vary delivery in the case of a pump or speed in the case of a motor. As shown in Figs. 1 and 2, a casing 4 having a supply port 20 and a delivery (or outlet) port 21 and closed by end plates 2, 3 houses intermeshing gears 6, 7, 8. The gear 7 is mounted on needle rollers 15 on the central eccentric portion 16 of a shaft 17 rotatable in bearings 18, 19. A control lever (not shown) may be fitted on the squared projecting end of the shaft 17 to adjust the eccentricity and the amount of intermeshing between the gear 7 and its adjacent gears 6 and 8. In another embodiment, four gears 24... 27, Fig. 3, are disposed in a closed chain. The space 46 enclosed by the gears communicates through a port 45, Fig. 4, and a pipe 44 with a liquid supply source and the space 48 surrounding the gears with a delivery (or outlet) port. The gears 25, 27 are mounted on a common control plate 29 having a shaft 34 extending outside of the casing fitted with a lever 35 movable over a scale 37, Fig. 6. Adjustment of bolts 41 adjusts the centres of gears 25, 27 so, e.g., gear 25 is moved closer to gear 24 and away from gear 26 and gear 27 closer to gear 26 and away from gear 24. The gear 26 is eccentrically mounted on a member having a shaft extending through and rotatable from outside the casing so that the gear 26 can be adjusted towards the gear 24 to allow for wear of the gear teeth. Screws co-operate with arcuate slots to lock the member in its adjusted position. The adjustable gears may be ad. justed to give zero flow or reverse flow.

Title: A new and improved method and means for purifying edible shell fish
IPC: A23B4/24
Filed: 1920-09-20
Abstract: 173,285. Masterman, A. T. Sept. 20, 1920. Fish culture; oyster culture.-A method of purifying edible shellfish, particularly mussels and oysters, consists in the application of hypochlorites and/or chlorine dissolved in sea-water of a strength which will interfere with the vital processes of the shellfish. As an example, cleaned mussels are placed on racks on the floor of a shal. low concrete or other tank, and sea-water is circulated through the tank, a filter, and an electrolyzer. The amount of chlorine produced is indicated by an ammeter calibrated for parts per million of chlorine. When the electrolyzer is in indirect circuit two small feed pipes lead into a sea-water circuit and a fresh water circuit respectively, and the chlorine in the latter circuit can be estimated by a standard chlorometer. After adjusting the feed pipe to this circuit, the readings of the chlorometer serve for determining the strength of chlorine in the sea-water. Chlorine gas or bleaching powder may be used.

Title: Preparation of hydroxy-terminated siloxane liquids
IPC: C08G77/16
Filed: 1964-06-30
Abstract: Hydroxy - terminated linear diorganopolysiloxanes are made by contacting a cyclic diorgano-siloxane trimer with water in the presence of an ion-exchange catalyst, and recovering the desired polymer from the reaction mixture.  The Si-bonded radicals may be alkyl, aryl, alkaryl, aralkyl, alicyclic or alkenyl radicals with or without cyano, chloro or nitro substituents.  The process, continuous or batch, is usually conducted at atmospheric pressure and at 20 DEG to 100 DEG  C., and desirably in the presence of a water-miscible solvent, the water being used in amount, for example, of 4 moles per mole of trimer.  In a typical Example (1) a mixture of hexamethylcyclotrisiloxane, acetone and water was heated to 55-56 DEG C. and a cation-exchange resin (viz. a sulphonic acid-containing styrene-divinyl-benzene copolymer) was then added, with subsequent stirring and filtering to yield a hazy solution which was poured into cold water (pH=8.4) covered with a layer of benzene.  The benzene layer was separated from the aqueous layer, dried and fractionated to yield (1) hexamethyltrisiloxane - 1,5 - diol and (2) dodecamethylhexasiloxane-1,11-diol.

Filed: 1924-11-12
Abstract: 247,288. Johnson, J. Y., (Badische Anilin & Soda Fabrik). Nov. 12, 1924. Dye preparations; azo dyes.-Plastic compositions or solutions of cellulose derivatives are coloured by means of inorganic or insoluble organic colouring agents, such as azo or vat colours or colour lakes, in a colloidal or nearly colloidal state. The method of preparation preferably consists in rolling the colouring agent into the mass until a solution of the latter no longer deposits the colour even in a dilute condition in a considerable time. Alternatively, the colour may be dispersed in a liquid before, addition to the cellulose ester, or it may be produced by chemical reaction with the solution. As examples of the first method gelatinized celluloid mass may be kneaded with Green P.L.X.. or celluloid or cellulose acetate with Lithol fast orange R powder, or with Indanthrene blue 2G.S.L. powder, or cellulose nitrate with the yellow dye from 5-nitro-4- amino-1-toluene and aceto-acetanilide, or celluloid plastic with Magenta A B powder, Methyl violet, the azo dve from amido-azo-benzene and ethyl-#-naphthylamine, or the calcium lake of Lithol rubine B.M. The plastic masses so obtained may be dissolved in solvents, such as amyl or butyl acetate, or a mixture of amyl acetate, methyl-cyclo-hexanone, and acetone. As an example of the production of the colouring agent in the solution itself, m-nitro-p-toluidine hydrochloride is dissolved in an amyl acetate solution of pyroxylin, diazotized, and mixed with a similar pyroxylin solution containing sodium naphtholate.
