Title: Improvements in holders for rolls of paper or tape
IPC: A47K10/38
Filed: 1935-05-18
Abstract: 454,731. Roll-holders. SMITH, F. 0., 133, Upper Holland Road, Sutton Coldfield. May 18, 1935, No. 14573. [Class 18] A holder for a roll of paper or tape comprises two spaced arms 15, Fig. 2, with upstanding portions 20 which enter transverse apertures in a cylindrical axle 10 for the roll whereby the latter is supported at a constant distance from the wall to which the arms are attached. The axle 10 comprises a tube or is formed from a sheet metal blank bent to cylindrical form and it is provided with end caps ; and the arms 15 are parts of a substantially U-shaped bracket formed with eyes to take screws 19 securing the holder to a wall, &c. In a modification, the bracket comprises stout horizontal posts 28, Fig. 5, with upstanding projections 30 which take into recesses in extensions of flanged spigot members 25 fitting into -the ends of the roll axle. The latter comprises tubes 23 engaging over the bosses of the spigot members 25 and a rotatable tube 21. The tubes 23 carry spring-pressed bolts 37 which lock the axle to the projections 30, and to unlock the axle-which can be done only after substantially all the roll has been withdrawn-the tube 21 is rotated so that cam slots 31 therein engage the upturned ends of the bolts 37 to withdraw the latter and thus allow the axle to be lifted away from the holder.

Title: Improvements relating to apparatus for x-ray fluoroscopy or photo-fluorography
IPC: H05G1/64
Filed: 1960-04-26
Abstract: 912,817. X-ray apparatus. OPTISCHE INDUSTRIE DE OUDE DELFT N.V. April 26, 1960 [April 29, 1959], No. 14625/60. Class 98(1). X-ray apparatus comprising an image intensifier tube having a variable magnification has a diaphragm of variable aperture between the X- ray source and the object, the controlling means for the aperture size and for the magnification being coupled together so that only that part of the X-ray beam is passed which is utilized to produce the visible image. In the embodiment shown in Fig. 1, the diaphragm 3 is in the form of two crossed pairs of lead strips, movable towards or away from each other so to enclose a square aperture of variable size (Fig. 2, not shown). After passing through the patient 6, the X-rays strike a fluorescent screen 9 to produce an image. This is reflected by a mirror 10 through an optical system 11, 12, 13 to produce an image on the photocathode of an image intensifier tube 15. The reduced and brightened image produced by the intensifier is projected on to a photographic film 17, and can also be visually observed by a viewing tube 22 which picks up the light reflected from a small mirror 23. The magnification produced by the tube 15 is controlled by, in this case, potentials applied to intermediate electrodes, and these are derived from a control box 29. The higher the magnification, the smaller the area of the fluorescent screen 9 actually pictured on the fluorescent screen of the tube, and the diaphragm 3 is adjusted so as to cut off the unnecessary rays. The diaphragm control is coupled to the magnification control so that both adjustments are made together. A further part of the light output from tube 15 is reflected by another small mirror 26 to a photomultiplier tube 28, whose output is fed back to the control circuit 4 of the X-ray tube 1 to control the filament current. Thus the brightness of the picture produced by the tube 15 can be maintained substantially constant irrespective of the magnification. Fig. 2 (not shown) illustrates a suitable switch panel, on which one of two alternative magnifications may be selected, the same switch at the same time switching in an appropriate resistance into the filament circuit of tube 1, and also adjusting through Bowden cables the diaphragm 3.

Title: Improved alkylation process
IPC: C07C2/62
Filed: 1955-05-20
Abstract: Saturated hydrocarbons are alkylated with unsaturated hydrocarbons in the presence of an inorganic acid catalyst to form higher boiling hydrocarbon products by contacting the reactants in an emulsified body comprising the materials maintained within a confined reaction zone, continuously withdrawing a portion of the emulsified materials from the reaction zone, rapidly separating the withdrawn emulsion by means of centrifugal force into a predominantly hydrocarbon stream and a predominantly catalyst stream, continuously recycling the separated catalyst stream to the reaction zone and recovering the product from at least a portion of the separated hydrocarbon stream. In a typical embodiment 4500 barrels of alkylate product are obtained when 3700 barrels of isobutane and 3200 barrels of butylene are treated with sulphuric acid in a 37 per cent emulsion.

An endless chain 23 driven by one or more power units 26 connected to a shaft 12 passes over the sprockets 14 and over idler sprockets 24 which alternate therewith and may be used as jockeys to adjust the chain tension. The clutches 17, 22 are operated either manually or automatically through a lever 28, the clutch 22 being engaged prior to the clutch 17 to ensure oil being circulated through the engine prior to its being driven.

Patent GB-665698-A (GB)
Title: Preparation of organic oxygen-containing compounds including glycol ethers and alcohols
IPC: C07C29/32
Filed: 1949-06-07
Abstract: Glycol ethers and alcohols are prepared by reacting a saturated alcohol, carbon monoxide, and hydrogen in the presence of a cobalt catalyst at 100-350 DEG  C., and above 100, up to 5000, preferably at least 1500, atmos.  Initial reaction products react further to give high molecular weight hydroxy compounds.  Recycling the alcohols first obtained gives similar results.  Cobalt salts such as the acetate, propionate, isobutyrate, naphthenate, stearate, and oleate, dissolved in the alcohol, cobalt carbonyl or carbonyl hydride or cobalt metal may be used, usually equal to 0.001-30 per cent of cobalt based on the alcohol.  Temperature is in general higher for primary alcohols than secondary or tertiary and increases with molecular weight.  For methanol, ethanol, ethylene glycol, propanols or butanols, at least 150 DEG  C. is generally used with reaction times not above 15 minutes.  With nonyl alcohol reaction is slow even at 280 DEG  C.  Metal, especially cobalt, carbonyls may supply the carbon monoxide.  Vapour or liquid phase reaction is used.  Diluents such as hydrocarbons, ethers or water may be present.  Pressure reaction vessels may be lined with silver, copper, precious metals or alloys or refractories.  In examples: (1) n-butanol, CO and H2 in mol. ratio 1 : 1, and cobalt acetate react at 253-255 DEG  C. and 2900-3000 atmos, for 10 minutes, the products including butyl formate, n-amyl alcohol, propylene glycol a - and b -n-butyl ethers, and minor amounts of the di-ether and of glycols; (2) methanol is similarly reacted, the CO:H2 ratios being 1 : 3, 1 : 1, and 3 : 1, respectively, at 200 DEG  C., and 1800-2000 atmos. for 5 minutes. Products boiling above methanol comprise ethanol and higher alcohols, propylene glycol a - and b -methyl ethers; (3) and (4) tert.-butanol gave mainly isoamyl alcohol and formates, various cobalt salts or the metal being the catalyst; (5) ethylene glycol is reacted at 270-273 DEG  C. and 2800-3000 atmos., glycerine being one of the products. Specification 655,237 is referred to.

Title: Blowing nozzle for the refining of metals
IPC: C21C5/46
Filed: 1955-05-27
Abstract: 774,454. Blast nozzles. HUTTENWERK OBERHAUSEN AKT.-GES. May 27, 1955 [May 28, 1954], No. 15420/55. Class 51 (1). A metal refining blast nozzle comprises an outer shell 1 closed at its respective ends by a perforated plate 6 and a blast header 4. The perforations 13 in plate 6 serve as blast outlet openings, whilst the header 4 distributes blast fed to it from a supply pipe by three pipes 16. The shell 1 is divided internally into a water supply chaniiel 3 and a water return annular channel 19 by nested tubes 7, 8 which, together with an extension 17 of the tube 7, form the blast supply route from header 4 to perforations 13. The blast is conducted from header 4 to the space 9 between tubes 8, 17, through tubes 15, Fig. 3. The space 9 is formed with six radially extending passageways 10 connecting channels 3 and 19 such that water entering the nozzle through tube 8 may leave through outlet 5. For more efficient cooling the interior of shell 1 near the nozzle mouth is roughened and provided with corrugations and the exterior of the shell is formed with grooved ribs 21. In order that the outgoing hot water may heat the incoming blast, copper is packed in tubes 7, 8, between tubes 15 and 7. That part of tubes 7, 8 enclosing tubes 15 may be dispensed with or the tubes 15 may be omitted, the blast in this case passing from header 4 to space 9 through the space between tubes 7, 8. Instead of water, any suitable cooling agent may be used.
