Title: Gas turbine engine fuel flow control system
IPC: B63H21/21
Filed: 1974-10-23
Abstract: 1479979 Automatic control of speed GENERAL ELECTRIC CO 23 Oct 1974 [26 Oct 1973] 45847/74 Heading G3R A control system for a gas turbine includes a compensation circuit responsive to load speed which modifies the input demand signal to the closed loop fuel control arrangement to account for changes in the volumetric heating value of the gaseous fuel supply. In the system shown, a demand signal is manually set on lever 10 and passes through junction generator 14 and adder 18 to the reference input of amplifier 24 where it represents the desired fuel flow. The other input of amplifier 24 represents the actual fuel flow to the turbine combustion chamber and a comparison of these flows produces an output signal from amplifier 28 which passes through a discriminator to control pumps 34 driven by HP turbine 36. The speed of turbine 36 together with the signal on line 32 is used in multiplier 40 to produce an actual fuel flow signal on line 26. The discriminator is supplied with other turbine parameters 30, e.g. temperature, acceleration control, start control which can override the signal on line 28. Output turbine 43 drives a variable pitch propeller 44 and the load speed signal on line 46 is made proportional to ship's speed. The compensating circuit consists of digital servo unit 50 which produces continuously an output signal representing the desired speed which corresponds to the actual speed on line 46 whenever the compensating circuit is brought into operation by opening the switch 62. At the same time, integrator 66 is made operational by opening contact 68a so that any change in actual speed will produce an error signal on line 58 which, after integration, is applied to adder 18 to modify the signal on line 22. The switches 62, 68 are opened by operation of manual control 64 to make the compensation circuit operational and are closed either manually by control 64 or automatically on movement of lever 10 to disable the compensation circuit.

Title: Process for the manufacture of 1,3-oxygenated , -oestratrienes
IPC: C07J1/00
Filed: 1976-11-08
Abstract: 1,3-Oxygenated 8 alpha -oestratrienes of the formula <IMAGE> in which R1 is optionally substituted alkyl, R2 is lower alkyl and Ac is alkanoyl, are prepared. These compounds are obtained by condensing a 3,5-dialkoxyphenylethyl p-toluenesulphonate with an appropriate indan compound. The reaction product of the formula <IMAGE> in which R3 is defined in Claim 1, is then cyclised to a 17 beta -acyloxy-1,3-dialkoxy-1,3,5(10),8,14-oestrapentaene, which is subsequently hydrogenated. Ether cleavage and subsequent esterification results in conversion of the compounds of the formula I into corresponding 1,3-dialkanoyloxy compounds. The 1,3-dialkoxy and the 1,3-dialkanoyloxy compounds can be used as agents for the treatment of postmenopausal women.

Abstract: 1314305 Vapour deposition monitoring INTERNATIONAL BUSINESS MACHINES CORP 12 Oct 1971 [9 Dec 1970] 47336/71 Heading G4H A device for monitoring vapour deposition in a deposition chamber comprises a crystal oscillator whose frequency varies according to the amount of vapour deposited on the crystal, a count representative of the frequency of the oscillator being periodically obtained and compared with a preset count representative of a desired thickness of deposition. In Fig. 1 the output from crystal oscillator 5 is mixed with a high frequency from oscillator 9 and the difference signal converted to DC pulses in shaper 17. Initially counter 23 is preset by a count representative of the desired thickness obtained from 27, which may be a set of switches or a store, to which is added a count representative of the initial frequency of the crystal oscillator, obtained by clocking the counter with the difference signal for a predetermined time, the combined count being passed to register 47. Thereafter the oscillator frequency is periodically sampled by clocking the counter 23 with the difference signal for the predetermined period and the result being compared in comparator 45 with the combined count in register 47. After each comparison counter 23 and counter 53 are clocked up by reference oscillator 57 until counter 23 equals the content of the register 47, counter 53 then indicating the amount of deposition yet to be deposited, which or its complement is displayed at 61. Counter 53 is then zeroed and clocked up for a predetermined time with a difference signal, obtained by mixing the crystal oscillator frequency with a lower frequency from oscillator 11, and after a delay clocked down by this signal for the same time. The remainder in counter 57 indicates the rate of deposition which is displayed at 65. Sequencer 33 controls the various sequences of the circuit.

Abstract: 1,089,628. Sampling filter for radioactive dust. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 11, 1965 [Nov. 30, 1964], No. 47910/65. Heading B1T. [Also in Division F2] During a period in which air is drawn through a filter 9 by a pump 1 to deposit a sample of air-borne radioactive matter on the filter, the flow rate through the filter is maintained constant in spite of clogging by means of a second filter 6, of sintered bronze, whose resistance to flow is reduced as that of filter 9 rises by reducing the amount of viscous oil which is directed on to filter 6. The oil is contained in annular reservoir 5, subjected through apertures 21 to the pressure in chamber 4 downstream of filter 6, and flows on to disc 6 via conduits 13, 15, auxiliary reservoir 16 and spaced distributors 17 (Fig. 2, not shown). The oil flow is controlled by a valve 14, comprising a mercury-filled tube 18, leading to a closed, air-filled vessel 19, and a ball 20 which floats on the mercury. Clogging of filter 9 reduces the pressure in chamber 4 and this causes ball 20 to rise and close conduit 15, whereby the filter 6 is quickly dried off and its resistance falls to restore equilibrium. A calibrated Pitot tube 24 indicates the air flow, and tube 23 the oil level in reservoir 5.

In the arrangement shown in Fig. 2, the fuel assembly comprises plutonium oxide fuel sealed in double-walled cans (52) (Fig. 7, not shown). The cans 52 may be arranged to make loose contact with the getter assembly 40 (which is spaced from the hot end of the thermopile by the fuel assembly) or, as preferred, are enclosed in a container (54) with an open side adjacent the getter assembly.  The thermopile 60 is compressively loaded by the tensioned wires 120 and is electrically connected to one or two terminals 86 passing through end cap 82. The getter assembly 40, thermopile 60 and insulation 16 are described in greater detail.  In the alternative arrangement shown in Fig. 8, the getter assembly 40 is immediately adjacent the hot end of the thermopile, but is spaced therefrom by a gap 178. The getter and fuel assemblies are contained in a surrounding container 150. By arranging the getter assembly to operate at a temperature above that of the hot end of the thermopile, it can operate more efficiently than otherwise to maintain a vacuum of #10<SP>-3</SP> torr within container 10.

Abstract: 974,239. Valves. A. WOBIG. Dec. 20, 1962 [Dec. 26, 1961], No. 48159/62. Heading F2V. A valve controlling the flow between an inlet 5, Fig. 1, and outlet 7, and the supply to and exhaust from a hot water radiator 3 is provided with a hollow, moving closure-member 13 that has opposed surfaces co-operating with separate seats 18, 19, ports 20 through the one end wall, and a tubular extension 11 leading into the radiator. The member 13 is moved axially by a manual control-knob 14 through a pin 16 and helical groove 15. With the member 13 on seat 18 all the water from the inlet 5 passes through the interior of the closure member and its extension 11 to the radiator, the colder water leaving the latter and passing to the outlet 7 via the seat 19 and an annulus 12 around the extension 11. When the member 13 is on seat 19 flow from the radiator is prevented and all the water travels from the inlet directly to the outlet. In any position intermediate the two seats the member 13 diverts some water through the radiator whilst the rest flows directly to the outlet 7. In a modification, the valve is actuated by a spiral bi-metal element 37, Fig. 2, responsive to room temperature, the inner end of the spiral being attached to an eccentrically mounted shaft 25 whilst the outer end is secured to a spring-loaded lever 38 which is pivoted when rotating the lid 28 of the bi-metal housing 31 to adjust the control point of the bi-metal. Rotation of the shaft 25 effects axial movement of the closure member 13 through a curved lever 22. The closure member 13, guide lugs 10 for the extensions 11, housing 31, and shaft 25 are made of heat-resistant, synthetic plastic material.
