Title: Improvements relating to fuel systems for gas-turbine aircraft engines
Inventor: ANDREWS WALTER AGNEW
IPC: F02C7/22
Filed: 1948-06-15
Abstract: 660,655. Gas turbine plant. ROLLS ROYCE, Ltd. July 15, 1949 [June 15, 1948], No. 16143/48. Class 110(iii) [Also in Group XXIX] In a fuel system for gas turbine engines for aircraft of the kind in which a fuel pressure difference is regulated automatically in accordance with the ambient atmospheric pressure, the pressure responsive means, such as the capsule 29, which is subjected to the ambeint atmospheric pressure is also subject to a load determined by a fuel pressure difference which is a predetermined ratio less than one of the fuel pressure difference which is to be regulated. The latter may be the pressure difference between the delivery and suction sides of the fuel pump 10 or the pressure difference across a throttle such as 17 between the fuel pump and the injectors 16. Fig. 1 shows an engine-driven swash plate pump 10, the stroke of which is controlled by a spring-loaded piston 12 under the control of a valve 22 carried by a lever 23 supported by a diaphragm 24. The lever 23 is loaded by an adjustable spring 28, by the capsule 29 exposed to the atmospheric pressure and by a tappet 30 actuated by a piston 31. The piston 31, Fig. 2, is subject to the fuel pressure between two restricted orifices 35 in a pipe 33 connected at one end to pump delivery pipe 15 and at the other to the pump suction by a pipe 27. The predetermined ratio is varied by suitable choice of the orifices 35. Where the regulated pressure difference is that across the throttle 17, the orifices are arranged in a byepass conduit which connects the two sides of the throttle 17. In this case, the piston 31 is also subject to the pressure upstream or downstream of the orifices. Where the system is used in conjunction with a minimum pressure burner control, the fuel supply to such control is tapped off between the orifices 35. Specification 577,016, [Group XXIX], is referred to.

Abstract: 362,400. Associated working of gramophones with kinematographs. FRIESS, H., 232, Friedrichstrasse, Berlin. May 26, 1930, No. 16205. Convention date, May 24, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] Continuous reproduction of sound from two or more disc, band, or the like machines b<1>, b<2>, Fig. 1, is effected by raising and lowering the sound-boxes or electric pick-ups m<1>, m<2> in turn by electromagnetic means o, Fig. 2, controlled by electric contacts u<1> Fig. 3, on the film u of the kinematograph. In the form shown, the disc machines b<1>, b<2> are driven by an electric motor a and the kinematograph machine d by a separate electric motor f synchronism being obtained by a switch arm i and a drum resistance h arranged between the driven shafts a<1>, d<1> and serving to control the speed of the motor a. Each pick-up m, Fig. 2, falls into contact with its record by movement about a pivot r when the circuit through the electromagnet o is broken, a dashpot k serving to steady the fall. The electromagnets o for each pick-up are controlled in sequence by contacts x<1>, x<2> on a drum v, Fig. 3, rotated step by step through a ratchet device operated by an electromagnet e energized by contacts u<1> on the picture film. The Specification states that the contacts x<1>, x<2> permit both pick-ups to engage their records at the same time during the transition period one running idle until the circuit through its reproducer is completed.

Filed: 1958-05-20
Abstract: 838,803. Packaging. IMPERIAL CHEMICAL INDUSTRIES OF AUSTRALIA & NEW ZEALAND Ltd. May 20, 1958 [May 20, 1957], No. 16231/58. Class 94(1). A method of packaging flowable materials comprises heating a thermoplastic sheet until viscous, discharging the material onto the sheet and controlling the distending of the sheet under the weight of the material. The sheet 2 is held between clamping rings 1 and heat is applied by a member 3. Material 6 is discharged onto the sheet which is supported by a piston 5, the latter descending until the required quantity has accumulated. The package may then be completed by twisting, the piston rotating with its load relative to the clamping rings. The package may be closed by any other means, such as by horizontally reciprocating sealers. A spout 7 may be incorporated during twisting or a removable rod may provide an aperture through the twist.

Title: Improvements in or relating to character recognition systems or apparatus
IPC: G06V30/224
Filed: 1967-04-11
Abstract: 1,129,572. Character recognition. SCANDATA CORP. 11 April, 1967 [21 April, 1966], No. 16480/67. Heading G4R. In a character recognition system, a computer edits text machine-read from a document on which editing characters are present in machinereadable form, in response to indication of character identity and location. Editing corrections to printed text on a document are made by writing the appropriate editing characters under the locations in the lines of print where correction is required, the possible editing characters having a vertical bar and a selection from six possible horizontal bars, the latter projecting from the top, middle and bottom of the vertical bar to the left and right respectively. The flying-spot scanner of a character recognition system performs a raster scan of each text character in a given line, then of any editing characters below the line, then of each text character in the next line &c., the resulting video signals being digitized and stored in a shift register capable of holding all the signals from one character. Threshold logic fed from the register recognizes character features, and patches of background to check registration, producing signals which feed AND and OR logic to recognize the character. The character identity is coded and sent to a computer together with the location of the character. By comparing the locations of text characters and editing characters the computer discovers where editing is required and performs it in accordance with the editing character identies. The meaning of a given editing character may depend on its location or the adjacent editing characters, as well as on its own shape (identity).

Abstract: 1423229 Evaluating angular information INTERNATIONAL STANDARD ELECTRIC CORP 6 April 1973 [7 April 1972] 16612/73 Heading H3H Apparatus and method for evaluating angular information contained in the envelopes of a set of N carrier frequency signals, e.g. from a magnetic compass, which are amplitude modulated with identical modulation envelopes in such a manner that the zero crossing points of the N modulation envelopes are equally spaced along an axis representing the angular information, e.g. signals of the form U 0 cos#e<SP>jwt</SP>; U o cos(#Œ120)e<SP>jwt</SP>, comprises converting these signals into at least one of the type U o e<SP>j(wt+#)</SP> and at least one of the type U o e<SP>j(wt-#)</SP>. In a preferred embodiment N=3 and the output signals from the compass are applied to a system of Œ120 degree phase shifters and resistances Fig. 1 (not shown) to produce a set of 3 signals of the form ¢U o e<SP>j(wt+#)</SP>; ¢U 0 <SP>ej(wt+#Œ120)</SP>, and a set of 3 signals of the form ¢U o e<SP>j(wt-#)</SP>; ¢U 0 e<SP>j(wt-#Œ120)</SP>. These 6 signals are each shaped into square waves and combined as a set of AND gates Fig. 2 (not shown), to produce 2 signals, containing a number of pulses in a time t given by 3(wt+ ##/360) and 3(wt - ##/360), where ## is the change in # in time t. These pulses are accumulated for the time t and the results subtracted to give ## = 60 degrees (n 1- n 2 ). If the gyro-compass is of the type where 1 degree change in heading α is equal to a 360 degree change in #, then #α = 1/6(n 1 -n 2 ), (n 1 -n 2 ) being the value retained in the subtracting counter. Read-out may be obtained in degree heading directly as follows: A pulse burst generator is provided which will generate exactly 360xn, xb pulses, where n=6 in this event. The output is passed to a "divide by b" circuit and a "divide by a" circuit, the output of the former being passed to the subtracting counter store. When activated, the subtracting counter store counts the pulses of the burst until it fills and this causes a flip-flop to be set to open a gate to allow the remainder of the burst from the generator to reach a counter and display. It is shown that for b=5; d=3, that the number displayed is representative of heading in degrees.
