Abstract: 407,259. Making rolling-mill rolls. PITTSBURGH ROLLS CORPORATION, 41st Street, Pittsburg, U.S.A. Aug. 18, 1933, No. 23097. Convention date, Oct. 4, 1932. [Classes 83 (i), 83 (ii), and 83 (iii).] Turning; cutters; moulds.-In the machining of the necks of rolls for use in rolling-mills, a rotary head 17 carrying a number of cutters 19 with edges lying in a plane perpendicular to the roll axes is moved axially along the roll so as to take cuts extending from the outer diameter to the finished diameter of the neck. In casting a roll, Fig. 1, metal is poured through one or more spouts 7 and then through spout 8 so as to fill a substantial portion of the mould cavity 9, a considerable excess of metal being cast above the portion (shown in dotted lines) from which the roll is to be formed. For making a roll with an effective width of 98 inches, a casting 25 feet 6 inches in height may be poured, the top being subsequently cut off. To machine the necks 14, 15, a plurality of cutting blades 19, of high speed steel or sintered carbide composition, are arranged in a rotary head 17 so that they take a wide cut extending from the outer diameter of the blank to the finished diameter of the roll neck, the tool being fed longitudinally of the blank. The cutters, which may be secured by wedges 20 or by close fitting in the slots, are each arranged at a slight angle to a radius of the head so that cuttings tend to be displaced away from the tool axis. Sixteen tools may each take a cut 1/64" thick, the tool being advanced “" per revolution. In a machine embodiment, Fig. 4, the roll is held centrally by means of radial adjusting screws 30, within housings 27 secured to the bed 26. Tailstocks 32, one at each end of the bed carry screws 31 which serve to move a spindle 34 into engagement with a centre point in the roll end. The cutter-head 17 is mounted on a hollow shaft 37 splined in a sleeve 38 rotatably mounted in the frame 40 and carrying a gear 41 driven from a motor 55 through reducing gearing including change speed gears 49, 50, shaft 43 and pinion 42. For feeding the shaft 37 longitudinally a fixed screw 60 surrounding the spindle 34 carries a nut 63 having gear teeth 64 driven from a variable speed reversible motor 79 through belt gearing 78, chain gearing 73, sliding shaft 71, and gears 69. A ball thrust bearing is interposed between the nut and a flange in the shaft 37. In order to balance the torque the cutter heads at opposite ends of the work are preferably driven in opposite directions. In the form shown two spaced cutter heads A, B are mounted in each shaft 37, the leading head A finishing the wider part of the roll neck while the head B fmishes the narrower end portion. The roll may be completed by polishing &c.

Title: Improvements in or relating to the manufacture of copper oxychloride
IPC: C01G3/06
Filed: 1936-08-25
Abstract: Copper oxychloride is obtained in a sandy or granular form by oxidation of cuprous chloride in chloride salt solutions by means of oxygen-containing gases in the presence of sulphate ions at temperatures above 60 DEG  C., say between 60 and 80 DEG  C.  The chlorides and sulphates preferably have different cations, for instance when using sodium chloride solution zinc, potassium, or ammonium sulphate may be added in amounts of 2-5 grms. per litre calculated as sulphur.  The solution to be oxidized preferably contains suspended oxychloride, and oxidation may be effected by circulating the solution by pumping through nozzles.  The process may be carried out continuously using a series of oxidation vats. After separation of the oxychloride, the residual solution is treated with cement copper to reduce its content of cupric chloride to cuprous chloride, and re-used for the treatment of fresh cuprous chloride. Examples of operation are given.

Title: Improvements in electrical generating apparatus
IPC: H02K44/08
Filed: 1947-08-25
Abstract: 648,272. Discharge apparatus. KAY, J. M., and McLEOD, T. S. Aug. 25, 1947, No. 23470. [Class 39 (i)] In an electrical generating apparatus of the kind in which a stream of working material such as mercury vapour is passed through a chamber transversely of a magnetic or electrostatic field, and electrodes are located in the chamber for connection to a load circuit, electrons are introduced into the stream by means of an arc. Mercury vapour from a boiler 1, Fig. 1, passes through a nozzle 3 into an expansion chamber 4 in which the heat energy of the stream is converted into electrical energy by the action of the injected electrons in slowing down the stream. The mercury then passes to a condenser 5 from which it is returned to the boiler 1 by a pump 7. The chamber 4 has one transverse dimension much smaller than its other transverse dimension. A magnetic field is produced across the narrow dimension. The wider dimension is bounded by the electrodes 13, 14 between which the external load is connected. In the bottom electrode 14 are located a number of mercury pools 16, each constituting with an adjacent electrode a mercury arc device for injecting electrons into the mercury vapour stream. In another embodiment, the magnetic field is dispensed with and an electrostatic field is established between a number of mercury pools 16, Fig. 4, and an electrode 19 disposed at the upstream end of the chamber 4. Arcs are established between the pools 16 and adjacent electrodes 17. The chamber 4 may be of square section. The load circuit 15 is connected between the electrode 19 and a grid 20 located at the point where the chamber 4 joins the condenser. Mercury particles of the stream are ionized; electrons are extracted by the electrode 19, whilst positive ions due to repulsion from the positive charge built up on the grid 20 act to slow down the mercury vapour stream. According to the Provisional Specification an inert gas such as argon or krypton may be used instead of mercury vapour.

[Class 106 (ii)] Relates to U-tube manometers of the type in which two vessels contain immiscible liquids, the meniscus separating which moves along the narrow base leg over an indicating scale, and consists in disposing the vessels coaxially or substantially coaxially one within the other so as to be unaffected by the considerable inclinations of the gauge experienced when mounted in aircraft. The vessels 10, 11 of cylindrical form are connected by a U-tube 12 having a much smaller section than either vessel. The vessel 10 is filled with a saturated solution of water in phenol and the vessel 11 with a saturated solution of phenol in water. The outlets 14, 15 serve to communicate with the sources of pressure. The apparatus is particularly suitable for use on gliders and in this case the inner vessel 10 is connected to a thermos flask 16 by a conduit 17 embodying a leak to the atmosphere connected to the outlet 14 and the vessel 11 is connected directly. For indicating air speed, the outlet 14 is connected to a Pitot pressure head and the vessel 11 to a static head. For use as a sensitive pressure gauge the leak is dispensed with and a tap placed in the outlet 14 which can be opened and shut to set the gauge. To avoid movement of the meniscus into either vessel through a sudden dive or ascent, the limb A ... B is provided at the top and bottom respectively with bulbs 18, 19 of sufficient capacity to take all the liquid in the chambers 11 and 10. In a modified form the chambers are made of spherical form and concentric, this form giving a wide scale in the middle of the range.

Abstract: 603,728. Indicating-instruments. BENDIX AVIATION CORPORATION. Sept. 13, 1945, 'No. 23670. Convention date, Oct. 31; 1944. [Class 106 (iv)] Indicating apparatus has a pair of indicating means normally adapted to move in unison and actuating means for moving one of said indicating means relative to the other, and is characterised by the actuating means comprising a single rotatable control member which is operable to hold one of the indicating means against movement and to rotate the other relatively thereto. The compass dial 13 of a navigation instrument is secured to a gear 17 fixed to a hub 18 driven by an inductive device 20. The gear 17 meshes with a gear 21 driven by a two-phase induction motor. As described in Specification 603,727, [Group XL (c)], a change in course causes a signal to be sent to the stator of the device 20, the rotor of which generates a signal which is. amplified and fed to the motor which drives the gear 17 until the rotor of the device 20 is brought to null, whereby the compass dial 13 has been moved relatively to a lubber line 14 an amount corresponding to the change of course. A smaller dial 15 is secured to a gear 27 freely mounted on the hub 18, the gear 27 meshing with two planet-wheels 28, 29 mounted on shafts 30, 31 carried by the gear 17, the shafts 30, 31 also carrying further planet-wheels 32, 33 meshing with a gear 34 secured to a gear 35, loose on the hub 18. The gear 35 has a friction surface 36 normally engaging friction surfaces on the planet-wheels 32, 33, so that the dials 13, 15 normally move in unison. When it is desired to move the dial 15 relatively to the dial 13, a knob 45 is pressed inwardly to press a spring brake 52 against the edge of the dial 13, and through a member 44 to rock a gear 37 about its bearing 38, whereby the gear 37 is brought into mesh with the gear 35. Rotation of the knob 45 now rotates a gear 42 to drive gears 37, 35 and through the planet gears drives the gear 27 and the dial 15, the frictional coupling of gear 36 with the planet-wheels 32, 33 being overcome. The needle 59 of a radio compass, as described in the afore-mentioned Specification, is confined under certain conditions between two spaced parallel grids 57, 58 etched or otherwise arranged on the dial 15.
