Title: Improvements in or relating to insulation for silicon irons
IPC: H01F41/02
Filed: 1942-08-07
Abstract: 560,667. Enamelling; electric tests. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 7, 1942, No. 11095. Convention date, Aug. 16, 1941. [Class 56] [Also in Group XXXVI] A method of forming an electrically - insulating film on a sheet of silicon iron consists in oxidising the surface of the sheet, coating the sheet with magnesium oxide, and then heating the sheet to cause the magnesium oxide to react with the film of oxide to form a tightlyadhering vitreous film. The magnesium oxide is suspended in water to facilitate application to the sheet, and silica flour may be mixed with the magnesium oxide if desired. The heating operation may form part of the annealing process to which the stacked sheets are submitted, and the coating of magnesium oxide may serve as a refractory to prevent the sheets from sticking to one another. The insulation resistance of the vitreous film is tested by a device in which two contact members 74, 76 pressed together by a spring 80, are connected by conductors to an ohmmeter 90 or other suitable instrument. The sheet is clamped between the contacts which have a definite area and are pressed against the sheet with a predetermined constant pressure. The contacts can be moved to clamp any desired area of a sheet. Before a measurement is taken, the device is twisted through an angle to test the mechanical strength of the vitreous film.

Title: Improvements in filtering apparatus
IPC: B01D25/12
Filed: 1925-05-02
Abstract: 255,960. Phillips, J. M. May 2, 1925. Block filters.-In filtering apparatus in which liquid is introduced into one or more holes in a block of porous material such as stone, earthenware, wood, celluloid, or porous metal, or in a pack of laminar construction, the separated material is removed from the holes by means of rods, an obturator at one end of the holes permitting compression of the material prior to discharge. When a filter block is used, it may be solid or built up of sections 10 arranged in pairs with metal guide-plates, 10<a> separating the pairs. The liquid enters by holes 14, the passage of which may be opened or closed by the obturator 25, and the filtered liquid leaves by a second set of holes 15 which communicate with a duct 22 forming the outlet. Cleaning rods 26 are attached to a piston 18 working in a cylinder 17, the pressure of the liquid to be filtered actuating the piston. The movement of the piston is controlled by valves 32, 33 in the supply pipe 29 and the valves and the obturator 25 may be controlled by a tail-rod 50 which carries tappets 51, 52, 53. A ram 94 is connected in the supply pipe for the liquid to be filtered, and as the pressure in the filter increases, the ram rises until it trips a lever 92 which supports a three-armed lever 89. One arm of this lever carries a weight 90, while another engages a lever 87, so that the falling of the weight operates the valves 32, 33 through a cable 86. The right-hand side of the cylinder 17 is connected to the exhaust 35, while the lefthand side is connected to the supply pipe 28, the piston 18 moving to the right. The obturator 25 is kept closed until the roller tappet 51 strikes a weighted lever 54 to rock a second lever 58 through a pin 57. The lever 58 is connected by link-work 59, 60, 62, 63 with the obturator. When the piston 18 has moved completely to the right and the sediment has been removed, the tappet 53 trips a bar 64 thus releasing a pair of levers 70, pivoted on a shaft 69 and carrying a weight 72. A bar 73 connecting the levers 70 engages pins 76, 77 on levers 74, 75 on the shaft 69, moving the levers counterclockwise. The lever 74 closes the obturator, and the lever 75 reverses the valves 32, 33. The piston moves to the left, the tappet 52 engaging a pin 85 and restoring the levers 70 and the weight 72 to their original position. Filtration recommences and continues until the ram 94 again trips the lever 92. In a modification, the piston 18 is operated by a separate hydraulic cylinder acting on a tailrod, and the valves 32, 33 both open on to the filter side of the piston, one valve being open when the other is closed. The operation of the piston, valves, and obturator is controlled by reversing gear from a constantly running shaft, tappets on the tail rod controlling the operations at desired intervals. An arrangement is described bv means of which the pores of the filter block may be cleaned after filtering by passing liquid, air, or gas through the block in the reverse direction to the path the filtrate takes.

Title: Improvements in or relating to machines for machining helical spur gears
IPC: B23F5/06
Filed: 1943-07-14
Abstract: 568,616. Gear-cutting. AEPPLI, A. July 14, 1943, No. 11477. Convention date, June 30, 1942. [Class 83 (iii)] In a machine for grinding or otherwise cutting the teeth of helical spur gears, the rolling motion for generating the tooth flanks is given to the grinding disc and the work is moved axially, a rotary motion to generate the helical formation of the teeth being given to the work by a rolling cylinder coaxial therewith and connected to a second rolling cylinder mounted on a perpendicular axis, this cylinder being rotated by a third rolling cylinder coaxial therewith and connected to a rectilinear rolling surface. The machine comprises a pillar 35 carrying vertical guides for the work slide 4 which is reciprocated by means such as a link 40 and driving gear (not shown), and carries the work arbor 6 and a dividing head 16 which is indexed step-by-step. Two grinding discs 25, mounted on opposite sides of the work axis, are angularly adjustable, to suit the work helix, on heads 31 which slide along straight guides 32 on sector-shaped carriages 26 which are oscillated about the work axis A-A by pinions and toothed sectors. During the oscillations, the heads 31 are given a rolling generating motion by steel tapes 29 connecting them to a fixed cylinder 28 mounted on a pin 41 coaxial with the work 13. A cylinder 1 is attached to the work arbor 6 and connected by crossed tapes 7 to a cylinder 2 on a perpendicular axis carried by the slide 4, and a further cylinder 3 on this axis is connected by tapes 9 to a rectilinear member 21. In one construction, the member 21 is mounted stationarily on the pillar 35 so that the vertical reciprocations of the slide 4 will generate the helical shape of the teeth according to the relative diameters of the cylinders 1-3 and the work, and in another construction the member 21 carries a roller which is maintained by a spring 48 in contact with a lever 22 pivoted to the pillar 35 at 23 the other end of the lever being maintained by a spring 49 in contact with a roller 24 on the slide 4. In this way, the angle of helix generated may be varied by altering the pivotal distances p, x without changing the cylinders 1-3, either by displacing the roller 24 or the pivot 23, or by placing the pivot 23 between the slides 4, 21. To enable the diameter of the roller 2 to be varied minutely, the roller may consist of split sleeves mounted on a tapered arbor 17, Fig. 4, and adjusted axially by nuts 19, 20, and the rolling cylinders and tapes may be replaced by toothed pinions and racks. Specification 351,092 is referred to.

Filed: 1929-04-15
Abstract: 327,025. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). April 15, 1929. Catalytic apparatus.- Endothermic catalytic reactions are carried out by heating the reaction chamber or chambers containing the catalyst, which is or are separated from the heating space, mainly or exclusively by heat radiation from suitable surfaces. These may be arranged on one or more sides of, or completely surround the reaction vessel. Such surfaces are heated by furnace gases, electric current &c., and preferably consist of materials of high heat absorptive or emissive power, e.g. metals or metal oxides, particularly those of the iron group. For example, a furnace for heating a bank of catalyst tubes R consist of three chambers, the central chamber K2 serving as a combustion chamber for the heating gases entering at A. The gases, heat the dividing walls, and pass throughthe lattice brickwork into the outer chambers K1 and K3, finally passing out at B. The heat is partly transferred by the gases flowing past the tubes, but chiefly by radiation from the hot walls between the chambers. Such apparatus may be employed, for example, in the catalytic conversion of methane and steam into carbon monoxide and hydrogen, or for the thermal decomposition of organic compounds, e.g. methane.
