Title: Improvements relating to aircraft engine fuel systems
IPC: B64D37/16
Filed: 1960-10-05
Abstract: 885,019. Gas turbine plants. GENERAL MOTORS CORPORATION. Oct. 5, 1960 [Oct. 5, 1959], No. 34132/60. Class 110 (3). [Also in Group XXIX] A gas turbine fuel system has in the fuel supply pipe a valve adjustable by a device, sensitive to the temperature of the fuel being supplied, arranged to move the valve towards closure as the fuel temperature falls so that the resultant back pressure of the fuel raises the fuel temperature until the valve moves in the opening direction. A gear-type fuel pump 30 supplies fuel from a tank 34 through a valve 38 and control apparatus 42 to the gas turbine fuel manifold 26. The valve 38 is connected through a line 46 with the inlet of the pump 30. The flow of fuel from the inlet 52 to the outlet 54 is controlled by an annular sleeve valve member 70 in conjunction with ports 66 in a sleeve 62. The sleeve valve member 70 is loaded by a spring 82, the loading of which may be varied by a retaining member 86. A flanged retaining sleeve 78 retains in position a pin 114 which holds a piston 90 a cup-shaped member 106 and the sleeve valve member 70 together. Holes 136 allow fuel access to the chamber 112 between the piston 90 and cup-shaped member 106. A temperature-responsive unit 116 has an expandable and contractible element 124 which may consist of wax impregnated with metal filings, arranged to abut against a plunger 120 supported for axial movement in a casing 118. The plunger 120 abuts against the piston 90 and when a predetermined fuel temperature is reached moves the sleeve valve 70 to the left. An opposite axial movement occurs upon decrease in temperature. A locknut 130 and screw 134 allow the position of the temperatureresponsive element 116 to be preset and locked in position. Since any increase in fuel pressure will be reflected by an axial force acting against the area 140 of portion 100 of piston 90 opposed by the pump inlet pressure acting on the opposite end area of piston 90 aided by the loading of spring 82, the valve will open when a predetermined pressure is reached at the inlet 52.

Title: Potato-base foodstuffs and process for production
Inventor: PESCHARDT WILLIAM JULIUS SYPLI
IPC: A23L19/12
Filed: 1958-10-28
Abstract: A potato-base foodstuff is prepared by mixing potato flour with powdered potato starch, adding water to form a dough, immersing the dough in boiling water, e.g. for 45 minutes, or ten minutes in a pressure cooker, and then drying the dough.  The dried product may be sliced, and the slices dried and immersed in boiling fat to form expanded and puffed pieces.  Preferably, 1 part by weight of potato flour, e.g. comprising dried mashed potatoes having a 4 to 5% moisture content, is mixed with 2 parts of potato starch sufficiently fine to pass a 100-mesh sieve and the dough formed using water, or alternatively, an aqueous sodium alginate solution containing, if desired, a small amount of trisodium phosphate to prevent dispersion of the dough when immersed in the boiling water; the latter may contain 1 to 3% by weight of a calcium salt, e.g. calcium chloride, to assist this function.  The dough is preferably extruded and cut into suitable lengths before being boiled.

Title: Improvements in or relating to amplifying arrangements employing automatic gain control
Inventor: CRAWFORD EDWARD CHARLES
IPC: H04N9/68
Filed: 1953-12-11
Abstract: 777,569. Automatic gain control. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 1, 1954 [Dec. 11, 1953], No. 34511/53. Class 40(5) In a radio receiver a common amplifier is used for two.or more sets of signals, of which one controls the gain. If, however this is absent, the A.G.C. voltage is derived from another set. A television receiver comprises initial stages 1 common to sound and vision, followed by separate vision and sound channels 2, 3, respectively. An A.G.C. voltage is obtained from the output of the vision channel 2 and applied to this channel and also to the common stages 1, via resistors 12, 13-and line 5. The sound channel 3 includes an A.G.C. diode 6 and control line 9. In such an arangement, if the video output is absent the common stages 1 may be overloaded by the remaining signals, since their A.G.C. is then absent.. To prevent this a diode 11 is provided, with its anode connected to the join of resistances 12, 13 and also via condenser 16 to the cathode of diode 6; its cathode is connected to a source of positive bias. The negative potential normally on the line 5 renders the diode 11 non-conductive: if, however the video is not present this voltage disappears and the diode then rectifies the sound signals reaching it via condenser 16 and so provides a substitute A.G.C. potential on the line 5. The diode 11 may alternatively be connected to an intermediate point in the sound channel and the delay bias on its cathode may be omitted, Fig. 2 (not shown). The diode 11 may also be arranged prior to the sound channel 3, for example after the mixer stage in the common stages 1, and control only the R.F. stage. The arrangement may also be used in a colour television receiver, to allow of operation as a monochrome receiver should the chrominance signal. disappear, or to prevent the luminance stages overloading.

In particular reaction with an α,#-dihaloalkane, a di(haloalkyl)ether, or a di(haloalkyl) amine yields the pyrrolidino, &c. radicals, and reaction with a 2,2-dimethyl-1,3-propanediol ketal of a ring monosubstituted aroyl alkyl halide followed by hydrolysis yields compounds in which R<SP>2</SP> is ring monosubstituted aroyl alkyl. Pharmaceutical compositions of the compounds I show CNS activity (either stimulant or depressant) when administered orally or parenterally with the usual excipients.
Patent GB-958068-A (GB)
Title: Method of inhibiting corrosion of metal tanks
IPC: C23F11/00
Filed: 1961-09-27
Abstract: The tanks of a tanker carrying liquid hydrocarbon are protected from corrosion by introducing into the tanks when empty a fog of a liquid, oil-soluble, water-insoluble, non-volatile inhibitor thereby effectively coating all the internal metal surfaces with the inhibitor and thereafter as the next step filling the tanks with the cargo of liquid hydrocarbon.  The hydrocarbon cargo is stated to aid in the interaction of the inhibitor with the metal surface.  The procedure is repeated after the discharge of each cargo and before a fresh cargo is taken on. Where ballast water is introduced into the tanks after discharging the cargo the further step may be taken of adding to the surface of this water a similar inhibitor having a specific gravity less than 1 and depositing the inhibitor on the metal surfaces by varying the level of the water in the tank. Suitable inhibitors are stated to be the complex products obtained by oxidation of hydrocarbon waxes, lubricating oils or petrolatum. Other inhibitors contemplated are: polymerized unsaturated fatty acids such as polymerized linoleic acid; monobasic and polybasic fatty acids of 12 or more carbon atoms and their amine derivatives such as myristic acid; hydrocarbon sulphonic acids and hydrocarbon phosphates of 15 or more carbon atoms and their amine derivatives such as the tetradecyl amine salt of dioctyl hydrogen phosphate and the ethylene diamine salt of dinonylnaphthalene sulphonic acid; mahogany sulphonate with acyloxycarboxylic acid or esterified alphahydroxy acid; hydrocarbon substituted imidazolines of more than 12 carbon atoms such as 2-heptadecylimidazoline; and a mixture of a hydrocarbon phosphate and alkenyl substituted dibasic acids of 12 or more carbon atoms such as octyl dihydrogen phosphate in combination with dodecenylsuccinic acid. If the inhibitor is not itself liquid it may be dissolved in a suitable carrier such as kerosene, gas oil or mineral oil.

Abstract: 1452241 Antiskid braking systems KELSEY-HAYES CO 12 Aug 1974 [24 Aug 1973] 35487/74 Heading F2F In an antiskid braking system comprising a hydraulic circuit for operating a wheel brake and means for modifying the actuation of the brake in response to a predetermined signal to prevent a skid condition the said means includes a pump such as a power steering pump 49 for delivering fluid under pressure, a member movable by fluid from the pump and a regulator for maintaining at least a predetermined pressure in the pump output in response to pressure in the brake circuit. The regulator includes a composite plunger having plungers 71, 78, a first area being exposed to the pump pressure and a second area being exposed to the pressure in the hydraulic brake circuit, a spring 76 providing a preselected bias. As the pressure from the master cylinder to the rear brakes is increased the plunger 78 biases plunger 71 to a direction which increases the pressure in a conduit 53. Actuation of the skid control modulator 19 causes a check and bleed valve 29 to close and isolate the wheel cylinders from the master cylinder supply and an expansion chamber plunger 37 retreats to relieve braking pressure. In the event of pump failure or heating of any of conduits 53, 59 or 56 a fail-safe device 84 delivers brake fluid direct from the master cylinder to wheel cylinders, the device 84 including an isolation valve 85 carried by a plunger 86 which has a bypass valve end portion 87 controlling flow through a port 88. A visual or audible warning is energised via a switch 111. Stopping and starting of the engine causes variation of pump pressure and causes movement of plunger 77 and other parts thus ensuring that they do not stick or bind in  their normal positions.
