Title: Fuel controls for gas turbine power plants
IPC: F02C9/32
Filed: 1955-12-19
Abstract: 815,484. Gas turbine plant. UNITED AIRCRAFT CORPORATION. Dec. 19, 1955 [Dec. 21, 1954], No. 36334/55. Class 110 (3). [Also in Group XXIX] In a gas turbine power plant 10 a lever 30 sets three cams 32, 34, 36 for co-ordinating both the propeller and fuel controls. The cam 32 sets, through the mechanism shown, the speeder spring 52 of a governor 54 which is rotated at a speed proportional to the turbine speed and operates a pilot valve 56. The cam 34 is connected through the linkage 90, 88 to a piston 94 located within a cylinder 86. The cam 36 adjusts the speeder spring of a governor which regulates the pitch of the propeller 18. The pilot valve 56 comprises a stem 58 controlled by the governor 52, 54 so that high pressure or drain pressure fluid is conducted to the chamber 66 of a cylinder 68 containing a piston 70. High pressure fluid is continuously supplied to the chamber 72 of the cylinder 68. The pistonrod 76 is connected through the linkage 80 to the follow-up sleeve 82 of the pilot valve 56. The piston-rod 76 is connected by the link 88 to the piston 94 of the reset pilot valve 86 which through a line 96 controls a reset servo-mechanism 100 which comprises a piston loaded by a spring 1021 which adds or subtracts spring force to the droop governor. The lower end of the piston-rod 76 engages a pivoted lever 118 located above the stem 116 of the fuel throttle valve 78. Interposed between the lever 118 and the stem 116 is a roller 114 carried by a rod 112 moved by a bellows 110 exposed to compressor inlet pressure and temperature. The arrangement is such that the steady-state fuel flow is always that determined by the setting of the cam 34. Specification 804,783, [Group XXXV], is referred to.

Title: Sawtooth current generating circuit
IPC: H03K4/32
Filed: 1963-09-18
Abstract: 1,021,116. Sawtooth circuits; pulse radar; cathode-ray tube circuits. RAYTHEON CO. Sept. 18, 1963 [Sept. 20, 1962], No. 36813/63. Headings H3P, H4D and H4T. In a cathode-ray tube deflection system the sweep velocity is adjusted by changing the turns ratio of a transformer feeding the deflection coils, an automatic shut-off circuit being provided to maintain the sweep amplitude constant. Fig. 2 shows a plan position indicator for a microwave radar system comprising a pair of deflection coils 26, 28 arranged to rotate around the neck of a cathode-ray tube 20 in synchronism with the aerial. Switches 35, 36, 39, 60, 91, 106, 124 are ganged together and are manually adjustable to provide a choice of ranges from one half to twelve miles. The deflection coils 26, 28 are connected via slip-rings 102 . . . 105 and switches 35, 36 which arrange the coils in series on the twelve-mile range and in parallel on shorter ranges. The time base is triggered by negative pulses at 70 which are amplified by valve 72 before being used to cutoff valve 76, forming part of a monostable multivibrator 76, 78. A positive-going pulse is thus initiated and passed via a cathode follower 90 to a driver valve 92, coupled to the deflection coils 26, 28 by means of an autotransformer 34. The sweep is terminated when the voltage developed across resistor 100 and diode 101 (in series with the deflection coils 26, 28) reaches a value sufficient to cut off valve 78 and restore the monostable circuit to its original state. The time base velocity is changed with changes in range by switch 39 which alters the tappings on the autotransformer 34. Switches 97, 124 also alter the time constant and bias voltages of the monostable circuit during different ranges. The screen voltage of valve 92 is also set to different values by switch 106. Damping diode 69 becomes non-conductive during the flyback switching damping resistors 62 . . . 68 in series with the deflection coils. Flyback pulses are rectified by diode 110 to provide E.H.T. supply for the cathode-ray tube.

Title: Process for producing formic acid
IPC: C07C51/02
Filed: 1930-12-24
Abstract: In the production of formic acid by the action of sulphuric acid on calcium formate in the presence of formic acid as a diluent, the necessity for employing large quantities of formic acid is obviated by the addition of sodium sulphate to the reaction mixture in quantities of from 1 to 10 per cent of the weight of the initial calcium formate.  Instead of adding sodium sulphate to the reaction mixture directly it can be formed in situ therein by the addition of sodium salts of volatile acids such as sodium formate, carbonate, or bicarbonate, or sodium hydroxide, employing an equivalent excess of sulphuric acid in each case. The quantity of formic acid used may be from 0:6 to 1 part for 1 part of initial calcium formate.  According to an example, calcium formate and formic acid containing sodium sulphate in solution are mixed in a closed pan while cooling, the equivalent quantity of sulphuric acid is added, and the reaction mixture is then heated in vacuo with stirring to distil off the formic acid.
