Patent GB-173230-A (GB)
Title: Improvements in the manufacture of colloidally soluble substances and of suspensionsor emulsions
IPC: C09K23/00
Filed: 1921-12-20
Abstract: The process of preparing colloidal solutions, suspensions, or emulsions with the aid of alkyl or aralkyl ethers of cellulose, starch, dextrin, and other carbohydrates of the general formula (C6 H10 O5)n as described in the parent Specification is modified by employing an ether which is soluble in cold water but insoluble in hot water, subsequently heating the colloidal solution or emulsion whereupon the ether together with the colloidal substance is precipitated, and after removal of the impurities and by-products as by washing with warm or hot water, and either drying the precipitate or coagulum or redissolving it in cold water. The colloidal solution, suspension, or emulsion may be produced in the aqueous solution of the cellulose, &c. ether, as by reduction, electric scattering, or precipitation; or the colloidal substance previously dissolved or suspended in water or in a solution of another protective colloid may be added to the solution of the ether. The process may be applied to the production of colloidal solutions of gold, silver, mercury, copper, tin, palladium, platinum, iridium, osmium, sulphur, selenium, tellurium, and of metal and other inorganic compounds, and of organic substances. In an example, an aqueous solution of a gold salt such as the chloride is mixed with an aqueous solution of a water-soluble ethyl or methyl cellulose, and is reduced by means of hydrazine hydrate, hydroxylamine hydrochloride, etc.; the colloidal gold solution is heated in a water-bath, and the precipitate or coagulum collected, washed with hot or warm water and redissolved in cold water or dried with or without a preliminary treatment with strong alcohol or alcohol-ether. In the parent Specification the preparation of a product suitable for use as a catalyst is described.

Patent GB-481220-A (GB)
Title: Production of olefine ethers
Filed: 1936-12-15
Abstract: In the production of olefine ethers by treating a b -chlorinated aliphatic ether in the liquid phase with a strong alkali, the reaction is carried out in the presence of a strongly basic amine, the amines used having a boiling point of not below about 105 DEG  C. and preferably above about 150 DEG  C.  About 5 to 20 per cent of the amine reckoned on the chlorinated ether may be present.  The alkali may be dispersed in the liquid in a finely divided solid form. Heterocyclic, alicyclic, aromatic or aliphatic amines may be used, piperidine, diamylamine, pyridine, aniline, dimethyl aniline and ethanolamines being specified. Triethanolamine is preferred, but mono- and diethanolamine are effective, either in the pure state or in admixture with each other or with triethanol amine.  In examples: (1) a mixture of excess bis-b -chlorethyl ether and finely divided sodium hydroxide is boiled in an iron kettle, and triethanolamine containing small quantities of mono- and diethanolamine is added. The reaction mixture is distilled through a fractionating column, a still head temperature of 90 DEG  C. being maintained.  The distillate includes chlorethyl vinyl ether, divinyl ether and unchanged bis-b -chlorethyl ether.  Water is added to the residual mixture in the kettle to dissolve the salt, and further unreacted bis-b -chlorethyl ether is separated by decantation; (2) chlorethyl vinyl ether obtained as in example (1), or a mixture of this with bis-b -chlorethyl ether, or the latter alone is stirred with flaked sodium hydroxide at the boiling point, and triethanolamine added.  The mixture is distilled through a fractionating column, a still head temperature of 50-70 DEG  C. being maintained.  The distillate includes divinyl ether and chlorethyl vinyl ether.  The latter can be re-used, or purified and employed as such.  If water is removed from the middle of the column, whereby a lower still head temperature can be maintained, the distillate contains more divinyl ether. Similarly, chloroisopropylisopropenyl ether and diisopropenyl ether can be prepared from bis-b -chloroisopropyl ether, vinyl isopropenyl ether from b -chlorethyl-b -chlorisopropyl ether, vinyl ethyl ether from b -chlorethyl ethyl ether, and vinyl butyl ether from b -chlorethyl butyl ether.

Title: Process for removing deposits from fixed catalysts
IPC: B01J8/00
Filed: 1974-08-06
Abstract: 1484272 Regenerating catalyst; pneumatic separating CHEMISCHE WERKE HULS AG 6 Aug 1974 [8 Aug 1973] 34579/74 Headings B1F and B2H A method for removing material which has been deposited on catalyst fixed in tubes of a multi-tube reactor comprises building up in the reactor an excess pressure, e.g. 1-10 atm. absolute, after discontinuance of the reaction, by means of a gas which is inert towards the catalyst and which does not recommence the reaction, and releasing the excess pressure abruptly so as to cause flow of gas in tubes in the direction of the multi tube reactor inlet, possibly supplemented by flow from a gas buffer chamber, thereby dislodging deposits from the catalyst. The excess pressure may be released by mechanically bursting a normally used 8,000 mm water column bursting disc forming part of the upstream reaction of the reactor, or by replacing this disc with a 4,500 mm water column disc before build up of pressure. The chemical reaction may be oxidation of naphthalene to phthalic anhydride using vanadium pentoxide catalyst, the excess pressure being built up with air.

Filed: 1933-12-08
Abstract: 420,259. Coating surfaces with liquid materials. OBERMULLER, H., 5, Scheibenstrasse, and SCHULZE, A., 37, Furstenwall, both in D³sseldorf, Germany. Dec. 8, 1933, No. 34608. [Class 19] [See also Groups XXVIII and XXIX] The brush or brushes for applying paint or the like to a surface are mounted on a rotary member and are displaced from the axis thereof. The brushes may, as shown at 32, be mounted at the periphery of a plate 33 adapted to be rotated through spur gearing 26 enclosed in a handle 23 and flexible shafting 28 by an electromotor 29 supported by springs 31 on a frame 30 which may be carried on the back of an operator. Alternatively, the shaft 25 carrying the plate 33 may be driven through reduction gearing by an electromotor mounted on the handle, or by a fluid motor operated by an aircompressor by which paint may be supplied to the brushes. Such compressor may comprise inner and outer casings 1, 2 enclosing a paint container 3. A detachable cover 4 carries an electromotor 6 which drives a piston pump 7 through reduction gearing. This pump sucks air through an automatic non-return valve 12 and forces it through a pipe 13 into the inner casing 2. An immersed tube 16 in the paint supplies it under the pressure of the compressor, which is limited by a safety valve, through a three-way valve 18 to a feed tube 20 by which it is led past a control valve 36 operated by a screw 37 to ducts 34 which supply it through adjustable nozzles to the brushes 32. The plate 33 may in addition carry other nozzles which supply paint outside the brushes. The brushes may be detachably mounted on the handle so as to be replaced by a single brush when it is desired to paint in a corner. When so desired, e.g. when not working at a height above the compressor, the air container 2 may be used to store compressed air. For this purpose byepass piping 38, 38<1>, 39 is provided. Air under pressure from the compressor 7 is supplied through a three-way cock 42 and pipes 43, 38, 381 to a storage chamber 40 between the containers 1, 2. After a while, the pump 7 is stopped, and this chamber 40 is placed into communication with the paint container 2 by a byepass 39 through a reducing valve 41 by which the pressure may be regulated. A stirrer 15 driven through reduction gearing from the motor 6 reaches down to the bottom of the paint container 2.

[Class 87 (ii)] Apparatus for moulding table jellies and other plastic substances comprises a rotatable mould carrier 5 and a ring of moulds 15 fixed thereto which are open at the inner and outer circumference of the ring, and a driving drum 7 into which the moulds 15 fit so that it closes them at the outer circumference, the carrier 5 and drum 7 being axially movable in relation to each other to expose the moulds 15 for removal of the moulded articles. In one form, a casing 1, Fig. 1, encloses the moulds 15 which are carried by two circular cages 5 rotatably mounted on a non-rotatable shaft 2 which is threaded at one end to engage with a threaded sleeve 3 which can be rotated by a hand wheel 4 to move the shaft 2 axially. This enables the cages 5 to be pushed alternatively into frictional engagement with a drum 7 which has rim grooves for driving-belts 8 connecting it to pulleys 9 on a shaft 10 driven by an electric motor 11, the drum 7 when rotated driving the cage 5 within it. Sprayers 12 direct cooling water on the outside of drum 7. The moulds 15, Fig. 6, are in the form of a grid with main cross-bars 15<1> between which the jelly tablets are formed and ribs 15<2> of less depth for producing the grooves in the tablets. Slots 15<3> may be provided in ribs 15<2> to produce webs which stiffen the jelly tablet. The moulds 15, which are closed on the outside by insertion in drum 7, are filled with hot liquid jelly supplied from a tank 19, Fig. 3, through a valve controlled by a rod 21 and a spout 20. The tank 19 is mounted on trunnions 19<1> on a truck 17 wheeled on rails through a doorway into the lateral compartment vacated by the cage 5 and is centred by engagement with a spike 18. The spout 20 carries a scraper which can be brought into contact with the faces of the moulds 15 to smooth the jelly by tilting the empty tank 19 by means of a handle 22. A spring-loaded plunger 23 engages a notch in the tank 19 to lock it in the central position. When the jelly has set, truck 17 is removed and the filled cage 5 moved back, a filling tank being then wheeled into position on the other side to fill the moulds on the other cage. The jellies are then displaced from the moulds onto a discharge conveyer 26 by means of a drum 28 rotatably mounted on a lever 27 which can be rocked by a handle 27<1> to bring the drum into contact with the moulds 15, rubber fingers 281 on the drum then pushing out the jellies. In another form, Fig. 8, the jellies are thrust inwards onto a collecting tray by rubber fingers 31<1> on a plate 31 which is carried by a pivoted lever 29 and is reciprocated by connection through a rod 32 and link 32<1> to a rod 33 working in a guide 34 and engaged by means of a stud with a box cam 35 driven by a belt 36. The rim of cam 35 has teeth 37 which engage pins 38 on the cage 5 to impart intermittent movement thereto.
