Abstract: 1,124,693. Compressors; gas turbine plant. UNITED AIRCRAFT CORP. Sept. 15, 1966, No.41211/66. Headings F1C and F1G. [Also in Division G3] A compressor stator vane control system comprises an actuator for varying the angular position of the vanes and means responsive to a function of the Mach number of the fluid passing through the compressor for controlling the actuator. In a gas turbine engine, Fig. 1 (not shown), the control system comprises probes (18, 22) subjected respectively to the static and total air pressures at the inlet to the compressor guide vanes (12) and connected to lines 20, 24. Line 20 is connected to sensor 66 to position a valve 60 according to the static pressure and both lines 20, 24 are connected to sensor 78 to position a valve 62 according to the dynamic pressure. Valves 60, 62 control the position of the spool 56 of a scheduling valve 28 in the hydraulic circuit of the vane actuator 14, port 90 in the valve being contoured to represent the schedule of the vane angle for a given value of the ratio of dynamic to static pressure, i.e. of Mach number. The fluid from port 90 acts to position the spool 106 of a servo valve 30 controlling the flow to either side of the piston 32 of the vane actuator 14, a feedback 100 from the piston rod 34 adjusting a valve 98 according to the actual vane position. In a modification, the pressure measuring probes (18, 22) are positioned downstream of the stator guide vanes. The control system may be used with axial or radial flow compressors.

Title: Apparatus for measuring calorific power of hydrocarbon compounds
IPC: G01N33/22
Filed: 1973-09-07
Abstract: 1432826 Measuring calorific values using radiation detectors YOKOGAWA ELECTRIC WORKS Ltd 7 Sept 1973 [29 Sept 1972] 42179/73 Heading G1A To measure the calorific value of a hydrocarbon such as crude oil or petroleum, γ or x-rays are used to derive a signal representing the carbon to hydrogen ratio of the material, and also to measure the sulphur content if the material under test contains significant sulphur; the measurements are combined with signals representing the density of the material and are used to automatically solve an equation which gives the calorific value. The derivation of the equation is given.  In Fig. 1 the carbon to hydrogen ratio is found by the R detector 1 which comprises a gamma or x-ray source 3 emitting radiation having an energy at which the mass absorption coefficients of hydrogen and carbon differ (e.g. 60 keV); after passage through the flowing sample SPL the radiation produces an electric signal at ionization  gauge 4. After impedance changing at 5 the signal is linearized by a log amplifier 6 and divided by a signal indicative of sample density and temperature obtained respectively by a vibration densitometer 14 and a thermometer 18. The sulphur concentration is similarly found, except that the radiation is around 20 keV, preferably 23-24.5 keV. This radiation is produced by a primary radiation, source 8, such as <SP>241</SP> Am or an x-ray source, and a target 9 e.g. of Ag and Sn or of In. The two density and temperature compensated signals X and C s  are used to solve an equation (9) (not shown) to give the calorific value of the sample. In a second embodiment one radiation source is used to measure both the ratio and the sulphur content, Fig. 2 (not shown). Here is a primary γ source emits radiation which passes to one ionization chamber via a first sample portion to measure the ratio and also emits radiation which strikes a target for conversion to x-rays before passing through a second sample portion to another ionization chamber to measure the sulphur. In a third embodiment a rotating body carrying two targets is used in conjunction with a primary source and an apertured mask to sequentially pass radiation of two different levels through one sample to one detector so that the ratio and the sulphur content are sequentially determined, Fig. 3 (not shown).

Title: Improvements in or relating to spring mechanisms and control apparatus incorporating such mechanisms
IPC: F16F3/02
Filed: 1965-10-06
Abstract: 1,055,547. Fluid analogue computers. HONEYWELL Inc. Oct. 6, 1965 [Oct. 12, 1964], No.42442/65. Heading G3H. [Also in Division F2] A pneumatic control apparatus 10 includes a spring mechanism (see Division F2) a pivoted plate 12 which forms part of the spring mechanism having adjustably mounted thereon a nozzle 52. A flapper 56 pivots about its mid-portion on the edge of the nozzle structure, one end of the flapper 56 co-operating with the nozzle 52 and the other end with an actuating arm 96 of an input unit 18. The position of the arm 96 is adjustable by a coarse adjusting screw 98 and a fine adjusting screw 104. The input unit 18 is fed with a constant pressure signal and a variable signal through a direct reverse acting switch 118 to actuate the flapper 56. The nozzle 52 is fed from a compressed air source through a tube 136, a filter, 138, a restriction 140 and a tube 142, a branch 144 from the tube 142 being connected to a pilot valve 132. The valve 132 amplifies the signal which is then transmitted to a rate unit 148 and subsequently to a capsule 152. The capsule 152 engages a cylindrical piston 46 depending from the plate 12 to apply a force to the plate in the form of feedback. Further feedback is applied to the plate by means of a reset capsule 192 acting on a further cylindrical piston 44 mounted on the plate at the opposite side from the pivot axis of the plate to the piston 46. A signal is applied to the reset capsule 192 through manually adjustable valves 160, 186 and a reset chamber 190 from a connection to the pilot valve 132 and the rate unit 148. The outlet conduit 170 of the pilot valve 132 is connected to an output conduit 226 for connection to a controlled element, for example a control valve in a process line, the pressure on the conduit 226 being varied in operation by the control apparatus 10 in dependence upon the difference in signals applied to the input unit 18.

Title: Improvements in or relating to cross-linked polyepoxide-thermoplastic resin compositions
IPC: C08G59/68
Filed: 1957-08-29
Abstract: An insoluble infusible resin is obtained by heating a polyvinyl halide, polyvinylidene halide or cellulose nitrate with a polyepoxide prepared by acid-catalysed epoxidation of a fatty acid ester. Preferably 1-90 parts by weight of polyepoxide are used for 100 parts of the polymer.  Suitable polyepoxides are epoxidized oils, e.g. epoxidized soybean, linseed, safflower seed, rapeseed or lard oil. The polymer may be mixed with the polyepoxide cross-linking agent by heating on milling rolls, or by casting a film from a solution containing both components, or a plastisol of the two components may be spread in a film on a surface and cured by heating.  In the example 10 parts of polyvinyl chloride and 4 parts of polyepoxide were dissolved in methyl ethyl ketone, the solution poured into metal receptacles and solvent evaporated.  The resultant films were heated in an oven at 150 DEG C. for 0,5, 2 and 4 hours.  The polyepoxides used were soya bean oil epoxidized by processes involving the production in situ of a percarboxylic acid with 0,5%, 1%, 2% and 4% of sulphuric acid as a catalyst.  The compositions may include fillers, pigments or other inert materials as desired.  The polyepoxides exercise a plasticizing function on the resin below the curing temperature.

Abstract: Insoluble polymers of N-vinyl lactams of the general formula <FORM:1031087/C3/1> where R1 represents hydrogen, or a C1 to C4 alkyl group, and n is 2, 3 or 4, are made by polymerizing a mixture comprising a lactam in the presence of a catalyst selected from oxides, hydroxides of alkali and alkaline earth metals, and the hydrides and borohydrides of alkali metals, and water at an elevated temperature for a period of time sufficient to induce incipient polymerization, then cooling the mixture to a temperature lower than the previous temperature, maintaining this temperature, and completing the polymerization.  The Specification contains a list of lactams of which N-vinyl pyrrolidone is exemplified.  Exemplified catalysts are sodium borohydride, sodium hydride, aqueous sodium hydroxide, aqueous potassium hydroxide and barium hydroxide.
