Title: A gas driven turbine
IPC: F02C5/00
Filed: 1932-02-10
Abstract: 382,497. Turbine plant. STRICKLAND, A., 1, Eastern Terrace, Dragon Road, Causeway Bay, Hongkong, China. Feb. 10, 1932, No. 3956. [Class 110 (iii).] Working fluid for a combustion gas turbine T comprises oil heated by a portion of the combustion gases and then mixed with compressed air in a number of firing bottles FB until combustion takes place. The gases are led to a number of receivers and to several stages of the turbine T, and the bottles FB are finally scavenged by fresh air supplied through ports G-G. A single rotary valve driven by an independent driving unit, with straight-through ports A-A .. F-F, each pair displaced longitudinally along the valve barrel, controls the flow of fuel and gases passing to the bottles, receivers, and turbine. A multi-stage rotary compressor, Fig. 4, supplies a storage reservoir CA. Fuel oil, supplied by a pump FP, passes by way of an air vessel AV, which ensures uniform pressure, and a non-return valve NR, to a fuel vaporizer FV which is surrounded by a heating muffle HM supplied with combustion gases at a low pressure by valve connections E-E, Fig. 2. Each bottle FB is supplied with fuel gas at vaporizer pressure through connections A-A on the valve, and compressed air enters the bottle through ports B-B until combustion takes place. Ports C-C lead high-pressure gases to a reservoir R-R, the gases then passing on to a highpressure receiver HPR. Ports D-D then lead the gases at reduced pressure to a low-pressure receiver LPR. Excess oil from the pump FP is byepassed back to the suction tank FT. Adjustable pressure control valves RV, RVI are fitted in the fuel supply line. A waste heat boiler may be included in the plant before the high-pressure receiver HPR, containing two sets of coils, one leading to the LPR being immersed in water, and the other acting as a superheater being placed before the HPR. An additional valve is required to isolate the coils when the firing bottles FB are being charged and fired. In the multiple-stage air compressor, Fig. 4, air is driven by a series of impellers through nozzles leading each from a lower to a higher stage, compression of the air taking place in the nozzles. For packing glands where the shaft passes through interstage diaphragms oil is led from the interior of the shaft against rings secured in the bosses on one side of the impellers. The rings revolve in grooves in the casing wall. Interstage cooling is used. The firing bottle FB is constructed in two portions, Fig. 7, capable of sliding upon one another, and mounted in a frame AA on bolts BB. Carbon or other rings P prevent leakage of the gases. " Leak-off " grooves L lead any escaped gases to a L.P. stage of the turbine. The Provisional Specification states that steel bands may be shrunk on to the bottle and the air inlet nozzles attached to the bands.

Abstract: 902,269. Valves. SINGER, E. Jan. 27, 1959 [Feb. 6, 1958], No. 3996/58. Class 135. A pressure-regulating valve comprises a casing 12, Figs. 2 and 3, containing spaced substantially parallel diaphragms 50, 51 dividing the casing into three chambers, adjustable loading means 69 between the diaphragms and means, such as an insert 35 for preventing movement of all but the central portion of diaphragm 51 towards and away from a seating 26 surrounding an inlet passage, the space 76 being connected to the outlet. In operation, the adjustable loading means, which may comprise a spring beam 69 supported at 71 and an adjustable abutment 42, acts through a push-plate 55 to lift the upper diaphragm 51 while pressure fluid passes from the inlet 91 through passage 78 to chamber 74 to act on the upper side of diaphragm 51 and through pusher 53, on central portion of diaphragm 50 to regulate the outlet pressure. A pressure gauge 89 on top of the casing may be replaced by a screwed member 87 which can be used for holding the valve closed or limiting its maximum opening. The diaphragms 50, 51 may be turned over to close the passage 78 and the chamber 74 be connected to the valve outlet by a pipe screwed into the hole for the member 87. In Fig. 6, the valve has a manually-actuated shut-off spindle 106 mounted in a gland 107 and a U-shaped spring bar 104 provides the loading means, while in Fig. 9, the loading means is formed by a short spring bar 127 bearing against a ridge 67 on pusher 53 and a ridge 129 on the insert 35. The setting of the valve may be varied by connecting the space between the diaphragms through a control valve to a source of air under pressure, an O-ring being fitted between the insert 35 and the pusher 53. Fig. 13 shows a pair of valves 10a, 10b with common inlet and outlet connections 167, 180 and which are set to open at different pressures so that only one valve lifts during periods of little demand. A spring bar similar to that of Fig. 2 may be used as the loading means, one end of the bar extending through a hole in an axially adjustable bolt for adjustment of the regulated pressure.

Title: Improvements in or relating to the Manufacture of Calcium Nitrate from Calcium Chloride and Sodium Nitrate.
Inventor: GILLBERT JOHN GUY
IPC: C01F11/40
Filed: 1916-03-27
Abstract: 124,780. Gilbert, J. G. March 27, 1916. Calcium nitrate is obtained by the addition of equivalent quantities of calcium chloride and sodium nitrate to a " nucleus solution " in such quantities as to produce a solution saturated with calcium nitrate at as high a temperature as practicable, say 80‹ C., and the precipitated sodium chloride is removed. Water is then added in quantity sufficient to make the proportion of water to sodium chloride equal to that in the nucleus solution and to provide four molecules of water of crystallization for the calcium nitrate which is to be separated. The solution is then cooled to a predetermined temperature to separate the calcium nitrate, leaving the nucleus solution, which is used again, and so on indefinitely, the subsequent cycles, however, including a step of evaporating, before the separation of sodium chloride, a quantity of water equal to that which was added in the first cycle. The nucleus solution is a solution saturated with calcium nitrate, sodium nitrate, and sodium chloride if the separation of calcium nitrate is to be effected below 25‹ C., or a solution saturated with calcium nitrate and sodium chloride if the separation of calcium nitrate is to be effected below 25‹ C. The separation cannot be effected above 30‹ C. in practicable quantities.

Abstract: 1,274,781. Sample holder. UNITED STATES ATOMIC ENERGY COMMISSION. Feb. 2, 1970 [March 13, 1969], No.4981/70. Heading G2J. A photo-metric solution analyzer includes a rotor assembly 1 having radially orientated cavities 10, 11, 12 disposed in an annular array and syphons 13, 14, 15 communicating with each of the cavities, and further includes means (not shown) to activate the syphons whereby the cavities are emptied. When the assembly 1 rotates a stationary tube 24 dispenses liquid into a central chamber 25 with a serrated periphery 26, whereby the liquid is introduced uniformly into first cavities 10. An overflow pipe 27 controls the amount of liquid in the cavities 10. A burst of compressed air from the chamber 25 causes the liquid to flow through first syphons 13 into second cavities 11. Additional liquids may similarly be introduced one at a time into the second cavities to form a mixture with the original liquid. A burst of compressed air from header 16 activiates second syphons 14 through which the liquid or mixture is transferred to third cavities 12, where its transmittance is measured by passing a beam of light through holes 21, transparent plates 4 and 3, and the transparent disc 5 in which the syphons and cavities are formed. Mixing of liquids may be facilitated by reducing the pressure in the header 17 to cause bubbles to pass through the mixture in the third cavities 12 from third syphons 15. A final burst of compressed air from header 17 activates the syphons 15 through which the liquid or mixture passes into a stationary waste trough 19 surrounding the assembly 1.
