Filed: 1927-06-08
Abstract: 301,938. Wade, H., (Cone Gear Corporation, and Cone, S. I.). June 8, 1927. Gear-cutting ; milling-cutters.-In generating worm wheels for gears of the Hindley type a cutting tool and the worm wheel blank are rotated in unison about perpendicular axes, the cutting edge of the tool being in a plane perpendicular to the tool axes and spaced apart from a parallel plane passing through the blank axis by a, distance equal to the radius of a coaxial circle formed by projections of the faces of the worm wheel teeth on a central section. The blank A is mounted on a turntable 10, carried on a cross-slide 9 which is supported by a plate 8 clamped to a lathe bed. The turntable is driven from the headstock 6 through gearing 17 and worm gearing 11, a hand adjustment being provided by a wheel 15 imparting axial movement to the shaft of the driving worm. A cutter-bar 22 is supported in blocks 23 which are slidable in the slotted hubs of gear wheels 25 mounted between the lathe centres and connected to rotate at equal speed by a shaft 26. The cutters may be fed towards the work by means of screws 29 operated by star wheels 30 coacting with fixed pawls 31. Two cutters 33 having parallel cutting-edges which are perpendicular to the rotational axis of the cutter bar may be employed. In operation the cutters are first set so as to take a light cut on the blank and are then fed to the required depth by means of the screws 29 while the worm-wheel blank and the cutter bars rotate at the correct velocity ratio. During the entire operation the rotational axis of the cutter bar remains coincident with the lathe axis and at the correct distance from the worm-wheel axis. In a modification only one cutter may be employed and after cutting one set of flanks the blank may be reversed or the cutter shifted to the other end of the cutter bar to cut the opposite flanks. In some cases such as for cutting worm wheels of large helix angle. and pressure, angle, secondary cutters 33<1> may be arranged intermediate the end cutters as shown in Fig. 1.

Patent GB-601692-A (GB)
Title: Improvements in or relating to synthesis of ethylated aromatic hydrocarbons
IPC: C07C2/70
Filed: 1945-06-19
Abstract: Aromatic hydrocarbons are ethylated by passing continuously, in admixture with not more than a molecular equivalent of ethylene or ethanol, through a granular solid phosphoric acid catalyst, with a contact time of 14-145 secs., at a temperature of 260-315 DEG  C., and a pressure of 200-900 p.s.i.  After separation of the mono-ethyl aromatic hydrocarbon, unreacted ethylene and aromatic hydrocarbon are recycled.  The initial gas should be free of higher olefins and may be obtained from coke oven or petroleum refinery gases or dehydration of ethanol as in U.S.A. Specification 1,402,336.  Alternatively, ethanol may be used as the feed, being dehydrated in situ by an alkylation catalyst consisting of phosphoric acid on "Sil-O-Cel" (R.T.M.) or kieselguhr at about 300 DEG  C.  Other aromatic hydrocarbons which may be ethylated include toluene, xylene and naphthalene.  The catalyst may be a stationary or moving bed. Preheated benzene and ethylene may be passed down an insulated catalyst tower, the products being passed to fractionating stills for separation of unreacted hydrocarbons and of monofrom poly-ethyl benzenes which may be recycled as desired.  In an example, 500 parts by weight of 85 per cent orthophosphoric acid and 117.5 parts of "Sil-O-Cel" are mixed with a little water, dried at 275 DEG  C. for 28 hrs., and screened.  Further examples give comparative results for the ethylation of benzene using such a catalyst at various temperatures, pressures and molar ratios of benzene to ethylene of 1.8-15 : 1.  The effect of increased pressure or molar ratio on production and relative yield of mono-ethylated hydrocarbon is illustrated.  The ethylation of toluene, and of naphthalene, the latter in admixture with benzene, is also exemplified.

Abstract: 1,216,744. Seaming non-metallic sheet material. ROBERTSHAW CONTROLS CO. 1 April, 1968 [5 April, 1967], No. 15646/68. Heading B5K. A sealed channel is formed between mating faces 80, 62 of two thermoplastic members 30, 32, e.g. plates, which have a channel 60 at the surface 62 of the member 32, by providing a strip of the thermoplastic material on the surface 62 outboard of and completely surrounding the channel 60 and by sonically melting the strip to form a weld band between the faces 80, 62. Apparatus for welding the plates 30, 32 comprises a welding horn 14 supported by a platform construction 18 vertically movable by cylinders 16 on posts 20. The plates 30, 32 are placed on a platform 34 parallel to the large contact area surface 28 of the horn 14 and which comprises a raised die block 52 on a plate 50 carried by a plate 46 adjustably secured by three screws 44 to a plate 36. The plate 32 is formed with a pair of ridges 70, 72, Fig. 4, on each side 64 of each channel 60, the outer ridges 70 being higher than the inner ridges 72. During the welding operation, the surface 80 engages the crests 76 of the ridges 70 initially and, after the melting of the crests 74 by the sonic vibrations of the horn 14, the surface 80 engages the crests 78 of the ridges 72 which become melted. The melted thermoplastic material flows into the space between the ridges 70, 72 to effect the weld. The pairs of ridges may be extended around the ends of the channels 60 as at 94, Fig. 2. Fluid inlet and outlet tubes 102, 104 and hooks 106 may be provided in the plates 32, 30 and, during welding, are received in cavities 108, 110, 112, 114 in the horn 14 and the block 52.

Title: Improvements in the properties of hydraulic cements and a process of their manufacture
Inventor: BURKE EDWARD
IPC: C04B28/04
Filed: 1958-05-15
Abstract: A hydrophobic Portland cement with a reduced dusting tendency is produced by grinding the finished hydrophobic cement with a minor proportion, preferably 0,2% to 1,5% by weight of a mineral lubricating oil, a mineral jelly or a mineral wax.  The hydrophobic cement is first formed by grinding together the cement with water repellant agents such as fatty acids, naphthenic acids and their alkali metal salts.  The dust suppressing additive such as a thin mineral lubricating oil on petroleum jelly is then ground with the hydrophobic cement either in the last stage of a multi chamber grinding mill or in an independent mixing stage. According to the Provisional Specification the water repellant additive may also be tall oil, chlor-x-cresylic acid and pentochlorophenol.

Title: Processes of preparing of high molecular weight substituted ethinyl carbinols

Abstract: 529,794. Ethinyl carbinols. TENNANT, W. J. (Armour & Co.). May 26, 1939, No. 15762. [Class 2 (iii)] High molecular weight hydrocarbon substituted ethinyl carbinols are prepared by reacting in a non-aqueous solvent an alkali metal acetylide or a substituted alkali metal acetylide with a ketone of the formula where R is an alkyl radical of at least 10 carbon atoms, and R<SP>1</SP> is an alkyl radical of at least 10 carbon atoms or an aryl radical, followed by hydrolysis of the alkali metal derivatives as formed. The preferred solvent is liquid ammonia, and the preferred conditions for the reaction are room temperature at a raised pressure. The products of the reaction correspond to the general formulae When liquid ammonia is used as the solvent, the alkali metal acetylide is not isolated, but reacted directly with the ketone. In examples (1) Acetylene is passed into a solution of sodium metal in liquid ammonia until the blue colour is discharged. Myristone is then added and the reaction mixture allowed to attain and remain at room temperature in a steel bomb for 48 hours. The product is hydrolysed with ice after the removal of the ammonia to give 1:1-ditridecyl- 2-propyn-1-ol. (2) Laurone is added to a solution of ethinyl sodium prepared as in example (1) and the product worked up as before to give 1:1-diundecyl-2-propyn-1-ol. If desired this example may be carried out using ether as a solvent, in which case the reaction is allowed to proceed for four days. (3) Stearone is added to a solution of ethinyl sodium prepared as in example (1) and the product worked up as before to give 1:1-diheptadecyl-2-propyn-1-ol. (4) p-Diphenyl heptadecyl ketone is added to a solution of ethinyl sodium prepared as in example (1) and the product worked up as before to give 1-diphenyl-1-heptadecyl-propyn- 1-o1. (5) Laurone is added to a solution of sodium vinyl acetylide prepared in an analogous manner to the ethinyl sodium of example (1) and the product worked up as before to give 1:1-diundecyl-3-vinyl-2-propyn-1-ol. (6) A solution of laurone in liquid ammonia is added to a suspension in liquid ammonia of sodium carbide and the product worked up as before to give 1:1:4:4-tetra-undecyl-2-butyn-1:4-diol.
