Title: Improvements in or relating to apparatus for grinding screw threads
IPC: B24B19/02
Filed: 1947-09-17
Abstract: 653,254. Forming screw threads by grinding. LANDIS TOOL CO. Sept. 17, 1947. No. 25365. Convention date, Feb. 21, 1946. [Class 60] A grinding wheel 12, Fig 4, has a roughgrinding section B, with a number of circumferential ridges 33 of successively increasing external diameter for progressively rough forming a screw thread on a workpiece 24 and, adjacent the larger diameter end of the section B, a finishing section C with a number of circumferential ridges 38 of substantially the same diameter and conforming substantially to the shape of the grooves of a finished screw thread. The section B may be pre, ceded by a plain section A which has a bevelled edge 32 and may be provided with a taper over the whole or part of its length. The ridges of section B may increase in both diameter and depth and decrease in crest width towards section C as shown in Fig. 4 or they may progressively increase in diameter and be of uniform depth as shown in Fig. 5. The grinding wheel forms part of a centreless grinding machine in which the control wheel may be cylindrical, concave or of the form shown in Fig. 4 in which a cylindrical section 47 ranges with a section 48 increasing in diameter towards the throat exit and provided with a succession of ridges 50 to provide greater surface contact with the work. The control wheel is mounted on a base angularly adjustable in a horizontal plane and slidably adjustable towards and from operative position. A base 21. Fig. 9, carries a vertically adjustable work rest 22 and supporting members 27 for guide plates 26 which are adjustable towards and away from each other to suit the diameter of the workpiece. One of the supporting members carries a dressing device 28, Fig. 7, for dressing the control wheel 15. A guard member 30 positioned so that it does not normally make contact with the workpieces prevents the latter from being ejected out of the throat. The grinding wheel of Fig. 4 may be formed by first using a crushing roller with a series of uniform V-shaped ridges and then truncating the ridges so formed with a diamond traversed at an angle to the wheel axis. The inclined traverse may be obtained either by mounting the diamond on the control wheel base or by mounting it on the grinding wheel fender to cooperate with a template. An alternative method of forming the wheel comprises using the diamond first to give the wheel its general shape and then producing the ridges with a contoured crushing roller. The grinding wheel of Fig. 5 may be formed by the latter method. Specifications 601,030 and 617,329 are referred to.

Filed: 1926-10-18
Abstract: 284,000. Berroth, A. Oct. 18, 1926. Gravity, measuring force of; magnetic tests. - Apparatus for detecting variations in the force of gravity, or in the vertical component of the earth's magnetism, comprises a mass m supported by two filars F2, F3' and adapted to be forcibly turned in azimuth by a third filar F1 connected to a torsion head T. Owing to the consequent raising of the mass. it becomes subjected to a restoring force due to gravity, or, if the mass is of magnetic material, the force is due to the vertical component of the earth's magnetic field. Variations in the value of the restoring force can then be detected by changes in the azimuth position of the mass m. The torsion applied by the wire F1 is preferably sufficient to turn the mass through a right angle from its position of equilibrium. The sensitiveness of the instrument can be estimated by noting the deviation of the mass when the casing R is evacuated.

Title: Improvements in or relating to the impregnation of pervious bodies and to impregnating solutions therefor
IPC: B27K3/15
Filed: 1928-09-13
Abstract: 322,789. Wade, H., (Bakelite Corporation). Sept. 13, 1928. Waterproofing; proofing-compositions; impregnating compositions for electric insulation.-- Pervious materials such as wood, fibrous compositions, paper, and cement, and compositions or structures having internal air spaces, such as coils for electrical purposes, are impregnated with synthetic resins of the phenolic type by using a solution consisting of a potentially-reactive phenolic resin capable of setting free ammonia during its transformation to the infusible state, and furfural. The quantity of furfural is at least sufficient to combine with the ammonia liberated, and is preferably in excess of this amount. Furfural is practically non-volatile at the temperature to which the impregnated material is raised to convert the resin, and remains in the material. The material may be impregnated by a vacuum process with a solution of potentially active resin in furfural, air being completely eliminated. The ammonia liberated combines with the furfural to form furfuramide. A minimum of 20 to 40 parts by weight of furfural to 100 parts of resin is necessary. In an example, a fusible phenol resin, with 5 to 15 per cent of a methylene containing agent such as hexamethylenetetramine, is dissolved in furfural, for example, 20 to 60 parts of the latter to 100 parts of resin. The material to be impregnated is subjected to vacuum, and the solution then allowed to impregnate it. The impregnated material is then, either with or without further shaping, heated to a temperature of 125-150‹ C. until the resin is transformed to the infusible state. Pressure may be simultaneously applied by using a closed vessel charged with air, steam or neutral gas, or a heated press, in which case higher temperatures may be used. In all cases the potentially reactive character is imparted to the non-reactive phenolic resin by incorporating therewith a sufficient proportion of a hardening agent containing methylene groups.

Filed: 1948-10-12
Abstract: 656,754. Gas filters. STEVENS, A. H. (Cuno Engineering Corporation). Oct. 12, 1948, No. 26535. [Class 8(ii)] [Also in Groups I and V] A filter element is made by accreting fibres on a ferrninous former from a liquid suspension of the fibres by the application of vacuum to the former, and directing jets of liquid against the formed element while suction is applied to it to trim it to the desired outer contour. The element is made by applying suction through a flexible pipe 34, Fig. 1, to a former 16 which has a removable upper disc 36 and is removably secured in a hollow block 33, which is attached to a framework 15, normally partly immersed in a fibrous suspension 12 in a tank 11. When the element 37, having a somewhat irregular contour 38, Fig. 3, has reached the desired size. the framework 15 is raised by a crank 20 attached to a disc 18 rotated by a motor 17, suction through the pipe 34 being maintained. At the same time a motor 25 on the framework 15 is set in operation to rotate a hollow shaft 24 carrying a hollow disc 27 with downwardlydirected orifices 28, and water under pressure is simultaneously supplied through a pipe 31 to the hollow shaft 24. Rotating jets 29 thus formed trim the outside of the element 37 to substantially cylindrical shape 40, and some of the liquid is caused by the suction to pass through the element and thus wash out excess suspension. The fibres used are preferably wool but may be mixed with up to 40 per cent of esparto, Lucca, asbestos and the like. The suspension is preferably an aqueous one containing synthetic resin (e.g. a phenol, urea, or melamine thermosetting resin, or a thermoplastic resin) in which case the element after forming is subjected to drying and resin-curing and setting operations. A preferred composition is 85 per cent wool fibre, 15 per cent esparto fibre, and 35 per cent resin by weight of the finished element; the amount of resin, however, may range from 15 to 60 per cent of the fibre content by weight.
