Title: Improvements in gear grinding machines
IPC: B23F5/06
Filed: 1950-02-22
Abstract: 667,613. Grinding. BUHLER, H. Feb. 22, 1950, No. 4576/50. Class 60. [Also in Group. XXII] A gear grinding machine comprises a toolholder which carries one or more grinding wheels 12 and which is mounted on a bed 1 both for rotation about the common axis A of the stationary workpiece 5 and of an involute-generating cylinder 3, and also for tangential movement relative to the workpiece under the control of tapes 6, the rotational movement being imparted by a power-driven shaft 25 which is parallel to the axis A and which drives a screwthreaded spindle 21 engaging a nut 19 pivotally connected to the tool-holder. The machine, according to the invention, further comprises an adjustable control device 35, 39 operated by the shaft 25 to reverse the drive to the spindle- 21 after pre-determined rotational movements- The tool-holder comprises a slide 10 which carries the wheels 12 and is reciprocated by power-means on a standard 9, a slide 13 which carries the standard 9 on rollers 18 to permit the tangential movement, and a table 14 which carries the slide 13 for radial adjustment and which is rotatable about the axis A. An electric motor 27 rotates the shaft 25 which both rotates, and serves as a pivot for, the shaft 21. The shaft 25 also rotates a gear-wheel 34 which carries the adjustable stops 35 to actuate a motor-reversing switch 39, 40. When one tooth space has been completed the workpiece is indexed. The tapes 6 are each mounted on an adjustable tension roller at one end and on the cylinder 3 at the other. The cylinder is equal in diameter to the base or pitch circle according to whether the wheels are set with their active faces making an angle of 90 degrees, or an angle equal to the complement of the pressure angle, with the tangent of the cylinder 3. In a modification, Fig. 7, the screw 21 is fixed to the bed 1. In a further modification, Fig. 9, the nut 19 is connected to the table 14 through a link 47.
Patent GB-657383-A (GB)
Title: Method and apparatus for thermally working minerals and mineral-like materials
IPC: E21B7/14
Filed: 1949-02-19
Abstract: 657,383. Blowpipe burners. LINDE AIR PRODUCTS CO. Feb. 19, 1949, No. 4599. Convention date. March 25, 1948. [Class 75(i)] [Also in Group XXI] In a method of piercing a hole in a mass of rock by continuously separating particles of rock from the parent rock with a flame produced by the combustion of a fluid fuel with a combustion supporting gas in a combustion chamber within a blow torch, the flame discharges from the combustion chamber at a velocity greater than 2,500 feet per second. In one form of the blowtorch the combustion chamber 17 is formed in a core 11 and at its exit tapers to a throat 19 then flares outwards to a discharge orifice 21. The core 11 is secured in a sleeve 26 sleeved on to an adaptor 27 until the core abuts against the adapter which is attached to a torsion tube secured to a core 49 positioned in a non- rotating barrel 48. Liquid fuel reaches the injector throat 15 of the combustion chamber 17 by hose nipple 59, passage 43, tube 42, supply duct 23 and injector nozzle 22, whilst oxygen reaches the throat 15 to intimately mix with the liquid fuel by hose nipple 46, annular groove 56, passage 47, tube 45, duct 25 and bore 13. Water is brought into the immediate rearward vicinity of the nozzle by way of hose nipple 41, tube 39, ducts 28, 29, annular chamber 31 and ducts 36 so that if the rock liquefies instead of breaking away by spalling, the molten rock is quenched and then broken down by teeth 37 formed in the sleeve 26. In a modified form a secondary discharge orifice is provided it being at an angle to the main orifice which is coaxial with the axis of the blowpipe. In a second form of nozzle the oxygen and liquid fuel fluid are delivered direct into the combustion chamber without the mixing as occurs when they are passed through the throat 15. The exit throat 19 may be dispensed with in which case the combustion chamber flares outwards continuously or else the outer portion of said chamber is cylindrical. The tube 39 is mounted in a continuously rotating chuck mounted on a carriage which is moved along a support by a screw thread.

Title: Improvements relating to injection moulding machines
IPC: B29C45/18
Filed: 1943-03-22
Abstract: 564,279. Injection-moulding machines. E.M.B. CO., Ltd., CATLIN, L. A., and COCKERILL, W. H. March 22, 1943, No. 4651. [Class 87 (ii)] The amount of material transferred from the hopper e to the cylinder a as the plunger g retracts to the position shown is dependent upon the length of travel of the plunger on the previous working stroke. As the plunger retracts, a chamber x formed between two relatively movable parts p, q of a transfer device also retracts, and material falls from the chamber through a feed passage d into the cylinder. The cross-head h which carries the plunger drives, with lost motion between stops v, w, a rod t passing loosely through part p and fixed to part q. When compressed air advances plunger g, compressed air advances also part p, this part being stopped at a fixed position by a shoulder s, the forward end thereof being then aligned with the left-hand side of the hopper discharge orifice o. If the plunger g travels only a short distance (due, say, to an excess of material in cylinder a), the part q also travels only a short distance, and the chamber x is small.

Title: Improved means for drawing wire by the wet process
IPC: B21C9/00
Filed: 1920-02-16
Abstract: 164,806. Smith & Co. (Wire Manufacturers), Ltd., F., and Fielding, A. W. Feb. 16, 1920. Drawing wire.-In a wire-drawing apparatus of the type in which the wire is drawn through the die by a winding drum from a winch immersed in a tub containing a lubricating liquid, and in which the wire is subjected to one or more preliminary drawing operations, and returned from the drum to the tub after each operation and wound on the drum at the final drawing operation, the wire in passing from the drawing pulley on the winding drum back through the tub is guided below the level of the lubricant and clear of the winch by eyes or the like. The wire 2 is drawn from a winch 7, mounted in a tub 6 containing the lubricant, through the die 4 by a pulley 3 with a large flange 3a secured to the flanged winding drum 1, and is led back to the tub at low tension round an adjustable guide pulley so as to avoid contact with the bed a. It is guided through the lubricant and out of contact with the winch by hooked or eyeleted spring clips 9. It then passes through a second die 10 and thence to the drum 1 on which it is wound. The wire passes over a wiper 11 secured to the tub. For performing a series of preliminary drawing operations extra drawing-pulleys of requisite diameters and guidepulleys are required.

Filed: 1950-03-02
Abstract: Alkyl benzenes are catalytically oxidized to the corresponding carboxylic acids by heating with an oxygen-containing gas in the presence of a lead tetra-alkyl, an aromatic aldehyde or hexachloroethane.  The reaction is preferably carried out at a temperature in excess of 140 DEG  C., with the promoter present in an amount of from 0.05 to 2 per cent by weight of the alkyl benzene. When an aromatic aldehyde is used as the promoter it is preferred to use the aldehyde corresponding to the particular alkyl benzene being oxidized.

If dry, water is added before freezing. The refuse can also be chilled before being compressed. The compressed mass can be stored in a freezer awaiting its disposal. In operation, refuse passes through a door 16 to compartment 42 where mechanism 35 and plate 40 which may be cooled compresses it against a freezer plate 38. Water can be added by sprayers 39. The frozen compact 28 is freed from the plates when they are warmed and falls through trap door 48 into the freezer 30. The falling compact trips a switch 52 and actuates a motor 54 which drives a conveyer 32 for a fixed time period and moves the compact out of the way of succeeding ones. A door 26 allows their exit when sufficient have collected. A bellows like compression mechanism is described in Figs. 4 and 5 (not shown).
