Title: Improved hydrocarbon conversion processes employing modified clay catalysts
IPC: C10G35/06
Filed: 1947-01-14
Abstract: Hydrocarbons are cracked, reformed or polymerized by contacting the hydrocarbons, under conventional conditions of temperature and pressure for the required conversion, with a clay catalyst that has been previously treated, in a dry condition and at a temperature greater than 1000 DEG  F. and preferably at no less than 1200 DEG F., with a gas or vapour which reacts with iron components in the clay to give an iron compound which is either readily volatilized at the temperature of the treatment or alternatively which is subsequently removed from the clay by leaching with dilute acid. Hydrocarbon oils with high sulphur content may be cracked using such a catalyst.  Gases or vapours referred to are chlorine, hydrogen sulphide, phosgene, carbon disulphide, sulphur monochloride, sulphonyl chloride, and sulphur.  When the clay contains a suitable component, the treating reagent may be selected to react with it to form such a gas or vapour in situ. For instance, sulphuric acid-activated bentonites may be treated with hydrogen which reacts with residual SO4 to form hydrogen sulphide.  In an example, acid-activated montmorillonite pellets were treated with hydrogen sulphide at 1400 DEG  F. for two hours.  After cooling, an equal volume of 15 per cent HCl was added and the mixture was frequently shaken during two hours.  The mixture was then heated at 140 DEG  F. for 30 minutes.  After decanting, fresh 15 per cent HC1 was added and let stand for 22.5 hours.  The clay was then washed several times with distilled water.  After drying in an oven at 200 DEG  F., the pellets were calcined in air at 1050 DEG  F. for two hours.  The catalyst so p  prepared contained 0.1 per cent Fe2O3 and was employed to crack a gas oil of high sulphur content, the volume ratio of oil to catalyst being 1.5.  The cracking was carried out at atmospheric pressure, at a temperature of about 800 DEG  F., and operating for 10 minutes with alternate regeneration.  The yield of gasoline was 30 per cent by volume.  In another example, kaolin clay was treated with chlorine for 2 hours at 1500 DEG  F.  A large part of the iron was volatilized as ferric chloride, the iron content of the clay being reduced from 1.4 to 0.3 per cent Fe2O3.  In cracking tests, the coke production was half of that obtained with clay from the same source calcined in air at 1500 DEG  F.  Specifications 255,300, [Class 1 (iii)], and 636,194 are referred to.

Title: Process for the production of phosphorus-copper steels and iron
IPC: C21C7/00
Filed: 1931-01-14
Abstract: In the production of steel or iron containing copper and phosphorus the phosphorus content is obtained wholly or partly by means of reducing agents such as aluminium, silico-aluminium, ferrosilicon, &c. which reduce the phosphorus from the slag and simultaneously deoxidize the slag and return manganese into the metal.  Thus in the Bessemer converter if the process is interrupted when the phosphorus content is 0,135 per cent it may be raised to 0,226 per cent by the addition of ferromanganese and silico-aluminium.

Patent GB-430514-A (GB)
Title: Stock-feeding means for a lathe or like machine-tool
IPC: B23B13/00
Filed: 1934-01-13
Abstract: 430,514. Lathes. HERBERT, SIR A., LLOYD, A. H., and TIPPLE, E. W., c/o Herbert Ltd., A., Canal Road, Edgwick, Coventry. Jan. 13, 1934, No. 1305. [Class 83 (iii)] A reciprocating-gripper feed for a lathe &c. includes a tubular carrier which is positively advanced in the feeding direction and resiliently retracted against the drag of the frictional contact between the carrier and stock while the stock is held by the main chuck, when there is no such drag owing to an insufficient length of stock being left in the chuck, the carrier is retracted further and actuates a motionpreventing or warning device. The reciprocating gripper 18 is carried by a bracket forming part of a slide 11, this is mounted on a further slide 10 reciprocated to feed the stock by means of a rotating disc and a connecting rod 14, 15 respectively. The two slides 10, 11 are resiliently connected by a spring 12, Fig. 4, which allows a small relative horizontal movement, the amount of which is controlled by adjustable stops 11<a> and 11<c>. When the gripper is drawn back over the stock after a feed movement the frictional resistance between gripper and stock causes the slide 11 to lag behind the movement of the slide 10, the spring 12 is consequently compressed and the abutment 10<b> engages the stop 11<c>. In the event of there being only a short length of stock, the gripper, on returning, no longer engages therewith and the spring 12 operates to move the slide 11 to the left relative to the slide 10 until the stop 11<a> strikes the abutment. The relative movement is used through an adjustable rod 20 to operate a switch 22 when the feeding mechanism is withdrawn, serving either to stop the mechanism completely or to disengage a part of the feed mechanism through an electrically-operated clutch mechanism, also, an audible signal may be given or a warning light 24 switched on. The switch circuit may be rendered inoperative during the periods when the chuck is opened-in which the slide 11 would normally spring back and operate the switch-by a further switch 31, 32 arranged on the main cam drum. Specification 358,251 is referred to.

Title: Manufacture of androstadiene-(1:4)-dione-(3:17)
IPC: C07J1/00
Filed: 1954-01-15
Abstract: Androstadiene - (2 : 4) - dione - (3 : 17) is manufactured by brominating androstadione-(3 : 17) in stages, a first bromine atom being introduced into the molecule at a temperature not above about 25 DEG  C., and further bromination being carried out at a temperature above 25 DEG  C. (preferably 35-40 DEG  C.) using not more than about 95 per cent of the theoretical quantity of bromine, and then splitting off hydrogen bromide from the resulting 2 : 4-dibromoandrostandione by reaction with not more than about double its weight of a base, especially collidine.  Both stages of the bromination may be carried out in glacial acetic acid, preferably in a fairly concentrated solution, in the presence of hydrogen bromide, and the second stage is advantageously effected more slowly than the first.  The dehydrobromination may be carried out at 170-220 DEG  C., if necessary in a closed vessel. When using collidine, part thereof, e.g. up to half, may be replaced by a high boiling solvent, e.g. cyclohexanone.  Examples illustrate the various features of the invention.

SEITZ-WERKE GES., Kreuznach, Rhineland, BOHMER, A., 31, Baumgartenstrasse, and GEBHARDT, G., 9, Kaiser- Wilhelmstrasse, both in Bad Kreuznach, all in Germany. Jan. 15, 1930, No. 1461. [Class 125 (ii).] Bottles &c. are first treated with a germicidal fluid and are then passed through germ-free spaces to a filling machine where the residual sterilizing medium is expelled and the bottles are sealed with sterilized corks. The bottles are first rinsed out and sprayed externally with germicidal fluid in a chamber from which they are transferred to a belt 3 which transports them under a filling machine 4 and a sealing machine 5. An endless belt 8 covers the bottle mouths in the travelling position until they reach the machine 4. The belt 8 passes through a germicidal liquid and is sprayed therewith during its travel. A screen 13 protects the filler 4. Hoods or bells are provided over the filling appliances or over the bottles during the filling operation. A screen 21 prevents germs from dropping into the bottles at the capping position. Alternatively the apparatus may be filled with germ-free gas under pressure. The sterile filling liquid is admitted into a vessel 29 by a pipe 26 and dispensed through filling units 31. The inert gas, e.g. carbon-dioxide enters a pressure vessel 35 through a pipe 32 and proceeds to the filling heads by pipes 36. Returned air passes through pipes 37 to a space 38 and to the atmosphere through pipes 42. A filtering layer 40 prevents the access of germs from the atmosphere. The spigot' of the filling cock has five bores. The bore 65 admits filling liquid to the bottle 47, the bore 50 admits scavenging gas to the bottle, and the bore 66 connects the bottle with the return air pipe 37. When in the operative position the bore 59 connects the bottle with the receptacle 45 in order to allow gas to escape. The bore 62 conveys rinsing or drip liquid to the receptacle 44. The corks are sterilized in a hopper and descend through a shoot to the sealing position. Each crown-cork is also sterilized again in the shoot by spraying.
