Title: Improvements in or relating to centerless grinding machines
IPC: B24B5/35
Filed: 1930-06-02
Abstract: 356,242. Centreless grinding machines. CINCINNATI GRINDERS, Inc., 3058, South Street, Cincinnati, Ohio, U.S.A.- (Assignees of Binns, G. W.; 3555, Edwards Road, Cincinnati, Ohio, U.S.A.) June 2, 1930, No. 16981. Convention date, June 4, 1929. [Class 60.] Driving and feed devices; guides and rests.-A centreless grinding machine particularly for grinding tapered bearing rollers, comprises a grinding wheel 12 and an opposed regulating wheel 15 and automatic means for delivering the work blanks successively from a hopper and moving them transversely into the path of a reciprocating device which carries them into and out of the grinding throat. The regulating wheel, mounted in a head 13 which is adjusted by means of a screw 14, is arranged to impart an axial feed movement to the workpiece which is supported during operation by a blade 16 mounted on a bracket 17. The regulating unit moves with a slide 18 which is provided with a bracket 20 supporting the housing of a cam shaft 27 which is driven from a motor 22 through change-speed pulleys 24. The work-pieces are fed from a hopper 28 through a tube 29 and are controlled by selector mechanism 31 having an arm 32 operated through a link 33 from a crank-disc 35 on the shaft 27. From the tube 29 the blanks are fed against a stop 36 and are received on a table 30 whence they may be pushed laterally into alignment with the grinding throat by a pusher 37 operated by a rock shaft 40 controlled by a cam 43 and spring 41. When the pusher 37 is operated, a stop prevents the delivery of any further blanks from the tube 29. The work-piece is.then gripped between the end 46 of a head 45 and an adjustable feed member 48, the head being mounted on a plunger 44 which is slotted to embrace the control cam 50 and is normally pressed outwards by a spring 52. The control cam is provided with a slot 55 forming a flexible outer finger 56 interlocking at its free end with an adjustable block 57. A number of interchangeable blocks having lugs 60 of different dimensions may be provided to vary the contour of the operative portion 56 of the cam. In operation, on completion of a grinding operation, the cam is in the position shown in Fig. 6. Further rotation of the cam causes the plunger 44 and the work-piece to be withdrawn clear of the blade 16 so that the work-piece falls into a short 67. The cam then moves the plunger forward into alignment with a fresh blank whereupon the pusher 37 is actuated to move the blank laterally on to the work rest between the members 46, 48. The portion 72 of the cam 50 then moves the blank forward into the grinding throat where it is fed slowly by the cam portion 56 until the final position, Fig. 6, is again reached.

Title: Improvements connected with the manufacture of composite titanium pigments
IPC: C09C1/00
Filed: 1926-07-08
Abstract: 278.791. Klein, C. A., and Brown, R. S. July 8, 1026. Pigments.-In a process for the manufacture of titanium pigments such as is described in Specification 243,081, in which a paste of barium and titanium sulphates are obtained, and which paste is poured into boiling, water optionally containing organic materials, whereby hydrolysis of the titanium sulphate occurs, barium carbonate is added to the water and is converted into barium sulphate by the sulphuric acid liberated by the hydrolysis. Since the paste of barium and titanium sulphates is always acid a certain amount of conversion of the barium carbonate will occur prior to the hydrolysis. Preferably a small quantity of an acid capable of forming soluble barium salts decomposable by sulphuric acid, or a water soluble salt of such an acid is present during the process. Hydrochloric acid or barium or sodium chlorides are suitable in this connection. Such addition, or the acidic radicle thereof, attacks the barium carbonate, yielding a solution of its barium salt which is decomposed by the sulphuric acid, the acid &c. being regenerated.. The amount of barium sulphate in the product is varied by varying the amount of barium carbonate added, and the product may be converted into a pigment by the process described in Specification 243,081.

Abstract: 1,188,182. Silica sol; silicates. PHILADELPHIA QUARTZ CO. 14 April, 1967 [10 May, 1966], No. 17166/67. Heading C1A. Stable hydrophilic silica sols are prepared by reacting elemental Si with water in the presence initially of at least 1À5% by weight NaOH whilst maintaining the SiO 2  concentration below 12%. As exemplified, Si and water are added incrementally to maintain the desired concentration. The resultant sol (which may contain sodium silicate) may be concentrated to 10-52% SiO 2  and if desired the resultant sol may be dried to form particulate SiO 2  or SiO 2  gel. Reaction temperatures from 20-200‹ C. are specified. Sodium, lithium or potassium silicates with high SiO 2 /alkali metal oxide ratios may be obtained by adding to the sol NaOH, KOH, LiOH or the corresponding silicates. The NaOH used for the reaction may be replaced by an equivalent amount of another alkali metal base, e.g. KOH, CsOH or alkali metal silicate. The sols, where desired after concentration, may have a particle diameter of 15-50 mm., a concentration of 10-52% SiO 2  at pH 9-10À2 and a SiO 2 /Na 2 O ratio (defined) of 180-500.

Abstract: 443,071. Mercury vapour rectifiers. LEHMANN, W., 45, Trabener Strasse, Grunewald, Berlin. June 14, 1935, No. 17183. Convention date, July 24, 1934. [Class 39 (i)] Striking back and high frequency oscillations are prevented in a mercury vapour rectifier by maintaining the vapour pressure within the discharge chamber 1 above the maximum value of the saturation current per channel in a grid baffle 6 placed in front of the anode 3. When current begins to flow from the cathode all first passes through one channel until-under given conditions of length L, see Fig. 1, and vapour pressurea maximum value is reached, when the current distributes over two channels, this process being repeated until all the channels carry current; the saturation value above referred to is this maximum per channel, but each channel can carry more current than this amount. The curve, Fig. 3, shows how this saturation current varies with increase of pressure p and the rectifier is worked at a pressure p<1> beyond the maximum i, so that even at low loads the current is distributed over all the channels ; the, anode is heated evenly by this means. The pressure within the chamber may be maintained by heating or by the introduction of a gas filling, i.e. helium, neon, xenon, argon or krypton ; with a length L = 30 mm. a gas pressure of the order of 0À1 to 0À15 mm. is used. The vapour pressure for saturation point increases with decrease of the length L. An inspection orifice 7 is provided by which the current flow through the channels may be observed when the rectifier is being built, the orifice being subsequently sealed.
