Title: Improvements in or relating to the manufacture of hard metal carbide articles, and more particularly to hard metal carbide articles of substantial size, such as rolling mill rolls
IPC: B22F3/14
Filed: 1937-11-01
Abstract: 506,728. Alloys; electric furnaces; rolling. METAL CARBIDES CORPORATION. Nov. 1, 1937, No. 29829. Convention date, Sept. 9. [Class 82 (i)] [Also in Groups XI and XXII] Articles such as rolling - mill rolls are formed from powdered material containing metal carbides and a metallic binder by compressing the material in a mould and locally and progressively heating the material in a zone moving in the direction in which pressure is exerted. The heating may progress from one end to the other or from the centre outwards to the ends of the mould. The articles formed may be solid or tubular. The carbides may be tungsten, molybdenum, vanadium, chromium, tantalum, or titanium, and the metal may be iron, cobalt, or nickel. The material is placed in a carbon or graphite mould 52 surrounded by carbon packing 54, an insulating sheath 51 and electric heating coils 60. The mould may be of refractory material such as magnesia, zirconia, and chromite. Compression is effected by a plunger or forging hammer 70 operated hydraulically. In one form, small slugs 101 of the powder are successively formed in the mould under heat and pressure and progressively welded together. Thus, powder 100a for the second slug is placed on the preformed slug 101. Smaller intermediate portions of the powder may be compressed between each slug to assist in welding. The slugs may be formed outside the mould under pressure, with or without heating, then superposed in the mould and welded together by progressive heating under pressure. Rings or tubes may be formed similarly in a mould 51, Fig. 20, by means of a spindle 57 and an annular piston 71. The material may be compressed by opposed pistons. When the mould is made of refractory material such as magnesia, the heating is effected by inductiom The heating coils 60 may be individually controlled so that the heating zone can be progressively moved or the heating coils may themselves be moved along the mould. The hollow cylinders may be used as working surfaces for rolls and may be provided with central shafts of steel or other metal which may be cast therein or secured thereto. The rolls may be mounted in a four-high mill.

Title: Digital to log-analog converter
IPC: H03M1/66
Filed: 1969-06-13
Abstract: 1,270,686. Selective signalling. TIME/DATA CORP. 13 June, 1969 [3 Sept., 1968], No. 30090/69. Heading G4H. An analogue signal representative of the logarithm of a number represented digitally is produced by summing analogue signals representing the characteristic and mantissa of the required logarithm. As described a 32-bit binary number is inserted into a shift-register 20, Fig. 7, the most significant bit I 1  occupying the extreme left-hand stage of the register, and a counter 22 is set to register 31-i.e., the counter is initially set to register the characteristic of the logarithm to the base two of the digital number if its most significant bit I 1  is a one-bit. If the most significant bit I 1  is not a one-bit, the register is left shifted until the most significant one-bit occupies the extreme left-hand stage of the register and for every shift unity is subtracted from the counter. Thus, when the most significant one-bit occupies the extreme lefthand stage of the register, the counter 22 indicates the characteristic of the required logarithm. The counter outputs C 1  ... C 5  then control switches C 10  ... C 50 , Fig. 8, coupled to binary weighted resistors 41 ... 45 to produce a current i 2  representative of the required characteristic. At the same time the contents M 0  ... M 10  of the top eleven stages of the register control switches M 10  ... M 100  coupled to binary weighted resistors 51 ... 60 to produce a current i 3  which, by a suitable choice of resistor 61, approximates to the mantissa of the required logarithm. These currents are then summed 63. Inductors or capacitors could be used in place of resistors, and a series circuit (Fig. 4, not shown) may replace the parallel circuit for the mantissa. The Specification discusses how to choose the value of resistor 61, and the absolute values of resistors 41 ... 45 and 51 ... 60.

Filed: 1952-11-28
Abstract: 709,368. Refrigerating, GENERAL ELECTRIC CO. Nov. 28, 1952 [Dec. 6, 1951], No. 30214/52. Class 29 The need for de-frosting the evaporator 4 of a refrigerator is detected by an arm 10 pivoted in a casing 6 and carrying a spring strip 15 having a button 16 formed with a collar 18, the arrangement being such that, when the door 5 is opened, it ceases to abut a rod 27 contacting the arm and a spring 24 urges the arm towards the evaporator. If defrosting is necessary, the button 16 contacts the ice before the arm meets its stop 25 and the spring 15 is flexed. This allows a slidable bar 19 of the arm to move to the left clear of collar 18 under the action of a spring 21 and a part 20 of the bar 19 actuates a switch 33 to de-energize the compressor motor and e.g. energize a heater for the evaporator. The bar 19 is reset by a bar 37 pivoted at 38 and moved to the right on rise of evaporator temperature by a bellows 34 connected to a thermal bulb 36. The bar 37 is loaded by a spring 40 the tension of which is adjustable to vary the temperature at which defrosting is terminated. Stops 44 limit the traverse of the bar 37.

Filed: 1925-04-06
Abstract: 242,105. Zimmermann & Jansen Ges., and Rappold, H. April 6, 1925. Hot-blast stoves.--In a hot-blast stove the various valves are interconnected in such a manner that they are always operated in their correct succession and a device is provided for effecting a slow opening of the cold blast inlet valve. As shown, the valves 1 - - 5 controlling the gas admission, cold blast inlet, and hot blast outlet respectively are connected to the plunger-rods 1<e> - - 5<e> of single-plunger cylinders 1<d> - - 5<d>. The latter communicate through the piping system shown with four double-plunger cylinders 1<a> - - 4<a>, the rods of which are interconnected by a system of links z with a four-way cock b adapted to reverse the flow of pressure fluid. The parts are shown in the position they occupy immediately after switching over to " blow," the fluid flowing through the pipe 1 and operating the piston 1<e> to close the valve 1; when the latter is fully closed the pipe 1f becomes uncovered to allow the fluid into the bottom compartment of the cylinder 1<a>, and thence through pipe 2g to the cylinder 2<d>. The valves 2 - - 5 are successively operated in a similar manner, the arrangement of piping being such that, whereas the valves 1, 2, 3 are opened, those at 4, 5 are closed. Pipes 1<h> - - 4<h> allow the exhaust fluid from the cylinders 1<d> - - 4<d> to pass into the middle compartments of the cylinders 1<a> - - 4<a> from whence it escapes into the waste pipe. The pipes 1<i> - - 4<i>, shown in dotted lines, are provided to complete the circuit between the single and double plunger cylinders on reversal to " gas," the pipes 1<f> - - 4<f> then forming no part of the fluid circulation system. In the pipe 4<h> is arranged a throttling member l which retards escape of the exhaust fluid and thus compels the valve 4 to open slowly. A non- return valve m is arranged in parallel with the throttling member l so that on reversal a free path, through the valve, is provided for the fluid.
