Title: Improvements in and relating to trueing the grinding surface of the grinding wheels of screw thread grinding machines
IPC: B24B53/08
Filed: 1934-05-24
Abstract: 427,064. Grinding screw - threads. TURRETTINI, F., 8, Rue des Vieux Grenadiers, Geneva, Switzerland. May 24, 1934, No. 15511. [Class 60] [See also Group XXII] In a machine for grinding screwthreads, means is provided for trueing the grinding - wheel to the exact profile of the thread, comprising the formation of a cam under control of the diamond moved along a master thread, and subsequent use of the cam to control the movement of the diamond in contact with the grinding - wheel, whereby as the diamond wears, a new cam surface, corresponding to the altered shape of the diamond may be cut. The work-piece 3 on which the thread is required is carried and rotated on a table 1 slidable on a bed 2 past the grinding- wheel 4, which is mounted on a support 5 adjustable towards and from the work. The support 5 also carries a master 7 having thereon a thread 8 of the size to be ground, and on the table 1 is pivoted an arm 10 carrying the diamond 6 ; the table also carries a transversely movable slide 20 supporting a disc 13, on which the cam 33 is to be cut by means of a cutting-tool, for example a milling-cutter 14, rotated at the same speed as the work. As the table 1 moves along the bed, the diamond moves up the side of a thread profile of the master, and then down the other side, these movements causing corresponding movements of the slide 20 by means of a screw 19 driven in one direction or the other by reversible bevel-gearing 15 .. 17, controlled by solenoids 27, 28, in the circuits of which are, respectively, contacts 31, 30 engaged by a contact 32 on the arm 10. When the cam has been cut, the screw 19 is disconnected from the slide, the cutter 14 is replaced by a roller having the same diameter, and the contacts 30, 31 are approached to engage the contact 32 on the end of the lever 10. The diamond is then, by movement of the table 1, located opposite the wheel 4 and, with the table and the cam 33 moving at the speeds used for forming the cam, the grinding-wheel is trued ; the process is repeated when the diamond has changed its outline due to wear. The master may be set, as shown in dotted lines, for work of a diameter larger than that of the master ; as the thread on the master becomÚs worn by the diamond, the master may be turned on its support 36 to present a new portion to the diamond.

Title: A method of making boron carbide
IPC: H02K23/36
Filed: 1937-06-04
Abstract: Boron carbide is obtained by a two stage process comprising the steps of electrically heating a furnace charge comprising boron oxide-carbon to form a product in which the total boron and carbon are not proportioned according to the formula B4C, indirectly determining the oxygen content of this product, mixing the product with boron oxide and/or carbon proportioned for removing all the oxygen thereof as carbon monoxide and for forming boron carbide from the total boron content, packing the mixture around the resistor of an electrical resistance furnace, and heating the mixture in an inert atmosphere to form a progressively enlarging ingot of boron carbide. Either the boron carbide B4C, or an alloy or solid solution thereof with a further amount of boron, may be so obtained.  The indirect determination of the oxygen involves determining the total boron, carbon, nitrogen and other impurities and calculating the oxygen by difference.  The partially converted or reduced materials containing boron and carbon, especially the waste or imperfect products derived from previous furnacing operations, e.g. the outer concentric layers produced when working in accordance with Specification 415,392, may be treated in the second heating stage after adjusting their composition by the addition of boron oxide glass and/or carbon (e.g. petroleum coke).  In addition to adjusting the charge for the second stage in the manner stated, a further amount of boron oxide and carbon may be added in the stoichiometric proportions for making boron carbide directly therefrom.  Specification 483,248 also is referred to.

Abstract: 517,913. Pigments. DU PONT DE NEMOURS & CO., E. I. May 26, 1938, No. 15727. Convention date, May 27, 1937. [Class 95] A composite pigment is prepared by mixing a titanium pigment with calcium sulphate containing less combined water than the dihydrate, hydrating the calcium sulphate by theaddition of sufficient water to form a thick slurry and, during hydration; subjecting the slurry to relatively high shearing forces by mechanical action to break down large particles and prevent an increase in particle size by crystal growth. The original titanium pigment used may be, for example, calcined or uncalcined titanium dioxide, a titanate of calcium, barium, magnesium or zinc, or a titanium pigment already containing an extender such as barium sulphate, magnesium silicate or calcium carbonate, while the calcium sulphate employed may be calcium sulphate hemi-hydrate, soluble anhydrite, a product obtained by dehydrating natural or precipitated gypsum, or mixtures of these forms. A quantity of water between about 3 and 7 times the weight of the mixed solids is usually added, and the slurry may be treated in a kneader having mixing blades, a ball mill, a pebble mill or a pug mill. The kneaded slurry is discharged, with the minimum of delay, and subjected to drying, for example, at temperatures below 200‹C., or to calcination, for example, at temperatures between 600 and 980‹C. According to the temperature employed, the average size of the calcium sulphate particles in the final pigment will vary from less than 1 micron to about 3 microns.

Abstract: 112,138. Bajanoff, W. Nov. 3, 1916. Integral calks; making. - Relates to a method of manufacturing horseshoes and consists in making the shoe from a metal bar of angular section, one of the flanges thereof being preferably thicker than the other. The bar cut to length is bent while cold in such a manner that the thick flange forms the wearing surface. As shown in Fig. 2, the thick flange 1 is continuous, whilst in Fig. 5 it is shown cut away at 3 leaving frost cogs at the toe and heels which may be toothed if desired. The flange may otherwise be cut away at parts to form a number of cogs or teeth. In all cases, the cut-away parts do not reach the base of the flange, so that the nails do not project under the surfaces 4. The provision of a thin flange 2 allows of the edgewise bending of that flange. Reference has been directed by the Comptroller to Specifications 1485/69, 1763/83, 13676/85, 5593/86, 8494/93 and 14492/14.

Title: Improvements in or relating to degreasing metal articles
IPC: C23G5/06
Filed: 1937-06-08
Abstract: Metal articles are freed from grease and adherent liquid or solid particles, e.g. prior to electroplating by treatment with a hot or cold agitated mixture of liquid chlorinated aliphatic hydrocarbon, a small proportion of water and water-soluble soap, and sufficient mono- or di-hydric alcohol to form a homogeneous liquid.  A little fatty acid, e.g. 0,1-0,5 per cent of oleic p  may be added. Treatment with plain solvent vapour and/or liquid may follow. Solvents specified are trichlorethylene, perchlorethylene, and carbon tetrachloride.  Alcohols used include methyl, ethyl, isopropyl, and butyl alcohols, methylated spirit, ethylene glycol, and etherified polyhydric alcohols containing not more than 2,OH groups, e.g. monomethyl ethylene glycol.  1-12 per cent may be used.  The soap may be olive oil soap, sodium oleate, stearate, or palmitate 1-7 per cent is suitable.  The water is preferably less than 2 per cent and may be contained in the soap.  A preferred composition is 957 lb. of trichlorethylene, 17,5 lb. of sodium oleate, 20 lb. of methylated spirit, and 5,5 lb. of water; it is preferably used boiling. Accumulation of solid particles in the bath is minimized by continuously or intermittently with-drawing cleansing composition and returning it after centrifuging with or without filtration. Circulation of the solvent in a multi-compartment apparatus may be maintained by returning the condensate from the cooling coils to the plain solvent compartment and allowing overflow from this compartment to that containing the composition; in such a case the solvent compartment is preferably charged with a mixture of solvent with alcohol in such proportions that the alcohol content of the composition is not altered by the circulation.  When water is introduced from the goods or by atmospheric condensation on the cooling coils it may be removed by passing the vapours condensed on the cooling coils of the composition compartment through a water separator before passage to the plain solvent compartment. Several composition compartments and several plain solvent compartments may be provided; preferably then the vapours from the composition are condensed and returned to the same compartment, and the plain solvent is circulated through its series of compartments and a vaporizer to effect self-cleaning, water being removed by passing the condensed vapours through a water separator or through soda ash.  Specification 444,818 is referred to.
