Title: Improvements in or relating to nut chamfering machines
IPC: B23G9/00
Filed: 1929-03-01
Abstract: 326,014. Fries, A. de. March 1, 1929. Combined turning and drilling-machines; turning nuts.-In a machine for countersinking the holes of nuts at both ends and chamfering both faces the nuts are fed automatically beneath two tool spindles in succession and are inverted during transit from one spindle to the other in order to present the unworked face to the second spindle. In a modification, two additional spindles may be provided for performing a finish. ing operation, the nuts being again inverted between the third and fourth spindles, or the last two spindles may be employed independently for performing the same operation as the first two. The two-spindle machine comprises spindles 8, 9,. rotated through gearing 3 - - 7 from a pulley 1 and carrying the tool heads 22, 23. The tools are fed axially by levers 10, 11 and cams on a. shaft 18 rotated through skew gearing from the pulley 1. The nuts are moved individually by hand from a plate 24 to an inclined shoot 25, Fig. 2, from the bottom of which they are transferred laterally by a pusher 27, Fig. 1, and a camoperated lever 28 beneath the tool-spindle 8. A half finished nut is pushed by the preceding nut from the spindle 8 to an inclined shoot 30 having a helical portion for inserting it and is then transferred laterally by a second pusher and camoperated lever 32, Fig. 2, to the spindle 9. The finished nuts are ejected by the preceding nuts and an inclined shoot 31 to a receptacle. Instead of the helical shoot 30 any other device may be used for inverting the nuts during transit from one spindle to the next, e.g., the nuts may pass along a vertically arranged semi-circular shoot which causes them to assume a vertical position. and then inverts them.

Title: Liquid starch
IPC: C08B30/16
Filed: 1946-03-05
Abstract: A stable liquid starch is prepared by mixing starch and water, heating the mixture, adding bluing, borax and salt and mixing the ingredients.  The mix may then be aged for from 24 to 72 hours and the ingredients strained and aerated or oxygenated, preferably with agitation and preferably immediately prior to bottling. Prior to the addition of bluing and borax the mix may be chilled to below the vaporizing temperature of pine oil and pine oil added.  The salt may be added at any stage of the process, in amount of from one-half to fifty grams per gallon of mixture.  In a preferred method 340 grams of starch are mixed with 2/3 quart of water, the mixture added to 2 quarts of boiling water, cooked to boiling point and boiled for 3 minutes, after which 1 1/3 quarts of cold water are added, followed by 15 cc pine oil, 7 cc bluing and 6 grams borax.  The mixture is then stored and bottled, salt being added at any stage.

Patent GB-879803-A (GB)
Title: Improvements in the production of alcohols
IPC: C07C29/141
Filed: 1959-03-04
Abstract: Alcohols having from 6 to 8 carbon atoms are produced by dimerising propylene and/or butylene at elevated temperature and pressure in the presence of an organo-aluminium compound, epoxidation of the olefines thus produced, rearrangement of the epoxides to aldehydes and hydrogenation of the latter.  Suitable organo-aluminium compounds are, for example aluminium triethyl, tri-isobutyl, triisopropyl, diethyl hydride, dipropyl hydride, di-isobutyl hydride or mixtures of two or more of such compounds. They are preferably used in amounts of 0.05 to 5 parts by weight to each part of the monomer.  The organo-aluminium compounds may be used in solution in a hydrocarbon, for example, cyclohexane, benzene, ethylbenzene and isopropyl-cyclohexane.  The dimerised products are oxidised to epoxides in known manner, for example, with acetaldehyde monoperacetate, peracetic acid or oxygen in the presence of alkali, and the epoxides rearranged to aldehydes with the aid of a catalyst, e.g. active aluminium oxide, silica gel or phosphoric acid.  The isomerisation stage is preferably combined with the following hydrogenation by using a two-stage reactor containing the isomerisation catalyst in the upper part and a hydrogenation catalyst in the lower part.  Alcohols obtained by the process are, for example, 2-ethylhexanol-1, 2-methylpentanol-1, and mixtures of 2-ethylhexanol-1, 2-methylpentanol-1, 2-methylhexanol-1 and 2-ethylpentanol-1.

Abstract: 841,431. Waveguide accessories. BRITISH THOMSON-HOUSTON CO. Ltd. March 8, 1957 [March 9, 1956], No. 7486/56. Class 40(8). [Also in Group XL(a)] The electrodes of a T.R. tube, rectifier, thermistor or like device are sealed into the bore of a metal plate which constitutes a short length of waveguide, the bore being sealed by one or more insulative hollow, bodies hermetically joined to the wall of the bore. The metal plate 1, Fig. 2, is held between the flanges 39 of a pair of waveguides 40 and is provided with a slot 3 which intersects bore 2 provided for the electrodes 7, 10 of a rectifier. Electrode 10 is a close fit and is adjustable within the lower part of the bore which is sealed by means of a metal evacuating tubulation 12. The lower end of the electrode 7 is provided with a sleeve 13 of insulation, e.g. glass, which is a sliding fit within the bore 2. An enlarged portion 14 of the upper part of the electrode is hermetically sealed by means of a glass sleeve 16 to a short tube 15 which is in turn sealed by solder 17 to the plate 1. The slot 3 is sealed before assembly of the device by inserting a carbon rod into the bore 2 and filling the whole of the slot with fused glass except for the space occupied by the rod. The plate 1 is in two parts brazed together along a joint extending at right angles to the section shown in the vicinity of the slot 3. In a modification (Figs. 3, 4, not shown), the glass 13 is sealed to the plate 1 instead of to the electrode 7 and is joined to the glass filling the slot 3. In the construction of Fig. 5, the electrodes 7, 10 project into a dumb-bell shaped slot and are surrounded by a ceramic tube 22 which is silver-soldered to the plate 1. The upper electrode 7 is sealed within a sleeve 15 which is sealed in turn within the bore 2, e.g. by a cold indium weld. Sealing of the lower electrode 10 is accomplished by means of a thin metal diaphragm 24 and a mass 26 of solder which deforms plastically when the electrode 10 is adjusted. Fig. 7 shows a T.R. tube having electrodes 28, 29 insulated from the bore 2 by a ceramic tube 30 soldered to the plate 1. The upper electrode 28 is sealed within the upper part of the bore 2 through a flexible diaphragm 32. Electrode 29 is sealed by glass within a sleeve 33 which is soldered to the plate 1. A transverse passage 36 is provided in the plate 1 for exhausting the tube and introducing gas or vapour filling.

Title: Process for the preparation of aromatic-group vib transition metal carbonyl compounds
IPC: C07F17/00
Filed: 1959-03-04
Abstract: Chromium, tungsten or molybdenum hexacarbonyl is reacted with an aromatic compound, these being the sole reactants in the system, to give a complex of the aromatic compounds and the tricarbonyl of the metal.  Reaction takes place at temperatures between 100 DEG  and 300 DEG C.  An excess of the aromatic compound may serve as solvent, but where convenient, a solvent such as a high-boiling saturated hydrocarbon, ether, aliphatic ester, silicone oil, or aliphatic polyester may be employed.  A long list of suitable solvents is included.  Aromatic compounds specified include benzene, phenol, amyl benzoate, propylbenzoate, butylphenyl ether, p-methyl anisole, mhexylaniline, 2 - amino - 4 - isopropylnaphthalene, N, N-dimethyl-o-methyl aniline, 2-methylbi-phenyl, tetrahydronaphthalene, b -methylnapthalene, anthracene, phenanthracene, mesitylene, meta-di-methyl benzene and m, m1- di-tertiary butyl-diphenyl.  Where the aromatic compound has a molecular weight below about 90, it is advantageous to carry out the reaction at a slightly elevated pressure, the carbon monoxide given off being vented through a condenser.ALSO:Complexes of aromatic compounds with tricarbonyls of chromium, molybdenum and tungsten may be thermally decomposed at temperatures of 250-400 DEG C. or above, preferably in an atmosphere of argon, krypton or other inert gas to obtain catalysts.  The starting material may be supported on infusorial earth or alumina.  The thermal decomposition in the presence of air, of mesitylene molybdenum tricarbonyl adsorbed on infusorial earth to give molybdenum oxide on the support is specifically mentioned.ALSO:A coating of chromium, molybdenum or tungsten may be produced on glass, glass cloth, or resins and other supports by the thermal decomposition at 250-400 DEG C. of a complex of an aromatic compound and a tricarbonyl of chromium, molybdenum or tungsten.  The decomposition is preferably carried out in an inert atmosphere e.g. argon or krypton.
