Title: Improved method of and means for determining the calorific value of combustible gases
IPC: G01N25/42
Filed: 1920-02-04
Abstract: 153,817. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). Feb. 4, 1920. Calorimeters.-In a gas calorimeter in which the gas and a stream of air, the rise of temperature of which is measured, are supplied in. constant volumetric proportions, the gas and air are initially subjected to like temperature, pressure, and saturation conditions. The gas-meter 7 and air-meters 6, 8, geared together by chains &c. 10, 11 are mounted in a common water-containing tank 12 to which air is supplied from a blower 14, gas being supplied to the meter 7 by a pipe 17 and regulator 18. Gas and air from the meters 7, 8 pass to a mixing - chamber 9 and thence to a burner 1, the products of combustion being deflected downwards by a tube 1 surrounding the burner. The air from the meter 6 passes to a pipe 3 surrounding the lower end of the tube 2 and is defected downwards, after passing through the pipe, by a cap 4 in order to compensate for losses due to incomplete transfer of heat from the burning gas. The temperatures of the air at entry and exit are respectively communicated to resistance thermometers 20, 21 arranged in a Wheatstone bridge circuit including arms 31, 32 and a galvanometer 23. A rheostat 29 is arranged in the bridge so that its resistance is divided between the arms which include the resistance thermometers. The rheostat arm is mounted on a ratchet-wheel 28 adapted to be turned by pawls operated by solenoids 26, 27, the circuits of which are controlled by the movements of the galvanometer needle. The needle swings over contacts 36, 37 and is intermittently clamped between them and contact segments 38, 39. The contacts 36, 37 are connected to contacts 47 - - 51 engaging conducting-segments on a rotating drum 41 so as to complete the circuit of one of the solenoids one or more times per revolution of the drum according to the extent of swing of the galvanometer needle. The rotation of the ratchet-wheel 28 also operates the pointer of a recorder 22 which records the calorific value of the gas. To compensate for variations of the specific heat of air at different temperatures, the two thermometers may be of different materials, or one of them may be in series with a wire of a different material. In a modification intended for dealing with gas at low pressure, a gas-meter of the kind shown in Figs. 3 and 4 is employed. This meter comprises a drum 52 having on its periphery five equal tubes 60 - - 64 each extending around three-fifths of the circumference. The tubes pass into blocks 59 communicating with orifices 58 formed in flanges 56, 57 on the end plates 54, 55 of the meter. Annular cover plates 65, 66 form inlet and outlet chambers for the gas. The meter 8 is similarly constructed, but without the cover plate 66. The air meter 6 comprises a cylindrical drum with five internal helicoidal fins. With such an arrangement of meters the volumetric ratio between the gas and air supplied is independent of fluctuation in the level of the water in the tank 12.

Title: Improvements in or relating to lathe or like tool assemblies
IPC: B23Q16/06
Filed: 1960-02-04
Abstract: 911,317. Lathe details. VAUGHAN ASSOCIATES Ltd., and COWLISHAW, M. May 4, 1961 [Feb. 4, 1960], No. 3936/60. Class 83 (3). A lathe or like tool assembly comprises a number of tools mounted on a shank carried in a tool-holder, a fluid-pressure-operated member for indexing the tools into operative position in succession, and fluid-pressure-actuated locking- means for the shank. A shank 2 carrying tools 4, 5, is indexed in a tool-holder 1 by a fluidpressure-actuated piston 9, having a rack 8, which co-operates with a pinion 7 on shank 2, and when the required tool is brought to its operative position,. a further fluid-pressureactuated piston 17 locks the shank. Supply of fluid to either end of piston 9, and to piston 17, is controlled by a valve 11, Fig. 5, and with the valve vane 30 in the dotted line position, fluid passes from conduit 12 through conduit 15 to the bottom of piston 9, which then moves to index shank 2. As the piston reaches the end of its stroke, fluid pressure passes through a port 20 and passage 19, to move a piston valve 23 to the left against a spring 24, whereupon fluid is supplied through a port 25 to move piston 17 to clamp the tool-holder. During this movement, fluid is exhausted from the top of piston 9 through conduit 16, valve 11, and port 28. The supply and exhaust conduits are reversed when the vane is moved to its other extreme position, fluid being supplied to valve 23 through a port 21. Piston 9, and pinion 7, may be replaced by a vane 31, Fig. 8, secured to shank 2 which is rotated to index the tools when fluid pressure is supplied to either one of the ports 33, 34. In a modification, to enable either of the tools 4, 5 to make more than one cut, before indexing, a fluid distributer 39, Figs. 9-11, is supplied in the fluid supply system. The distributer comprises a number of valves 40 which can be located in the body 38, so that a recess 41 in each valve can connect ports 42, 43 or alternatively can cut them off from each other. Body 38 is rotated by a pawl, operated at each traverse of the tool slide, which cooperates with a ratchet wheel 44 on the body. In operation with a valve 40 set to connect ports 42, 43, fluid pressure passes from pipe 48, Fig. 11, through a recess 41, into a chamber 50, whereupon a piston valve 51 is moved into the position shown, thus supplying fluid through a port 54 to a port 34 to rotate vane 31, and therefore shank 2, into the position shown, whereupon piston 17 locks the shank. If the next valve 40 is set to connect parts 42, 43, vane 31 will remain stationary, but when a valve cuts off the connection, pressure to chamber 50 is cut off, and a spring 52 moves valve 51 to close port 54 and open ports 53, 55, so that pressure is supplied to port 33, to rotate the vane, and to index shank 2.
