Title: Digital radar or sonar processing
Inventor: JALES RICHARD JAMES
IPC: G01S7/285
Filed: 2008-08-29
Abstract: A pulse radar or sonar system amplifies the signal received by an antenna (31) of the radar system or a transducer of the sonar system is amplified and then subject to linear demodulation by a digital linear receiver. An antialiasing filter and a sub-sampling analog-to-digital converter (sampling below the Nyquist frequency) are between the amplifier and the receiver. The receiver may also include a further digital filter. The results may be displayed in false colour, the colors being indicative of the received signal amplitude. The system operates at different ranges, the modulator may produce pulses of two pulse patterns differing in pulse duration and inter-pulse spacing, those pulse patterns are introduced and used to form two radar images with the two images being derived from data acquired in a duration not more than twenty times larger than the larger inter-pulse spacing, or for a radar system, larger than one half of the antenna resolution time.

Title: Process for finishing dyeings
IPC: D06P1/607
Filed: 1959-03-23
Abstract: In the dyeing of nitrogenous fibres, such as wool, silk or polyamide fibres, with a reactive dyestuff containing at least one reactive halogen atom, from an acid bath having a pH of at most 5, improved dyeings are produced by raising the pH of the dyebath to above 6 after the fibres have absorbed the desired quantity of dyestuff, by the addition of, for example, ammonia, ethanolamines, hexamethylene tetramine, trialkali metal orthophosphates or alkali metal polyphosphates or bicarbonates.  The dyebath contains acetic acid, and if desired sodium sulphate, and dyeing may be effected at 80 DEG -90 DEG C., or at the boil, or at temperatures above 100 DEG C. under pressure.  In the case of certain dyestuffs, more level effects are obtained by the addition to the dyebath of the nitrogenous levelling agents employed in Specification 878,021, or a cation-active compound such as cetyltrimethyl-ammonium bromide or a high molecular weight polyglycol ether of an aliphatic alcohol.  Reactive soluble dyestuffs of the stilbene, nitro, triphenylmethane, phthalocyanine, anthraquinone and metallizable or metalliferous azo series may be employed.  Mixtures of wool and cellulose fibres may be dyed by the process, a substantive dyestuff being added to the dyebath after raising the pH.  The fastness of the dyeings on the cellulose fibres may be increased by an after-treatment with, for example, a formaldehyde-dicyandiamide condensation product. Examples of dyeing are given.

Abstract: 697,597. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. April 24, 1952 [April 25, 1951], No. 10332/52. Class 38 (iii) In order to start a split phase induction motor a selector switch 37 is moved to engage a contact 9 so completing a circuit through relay coil 11, centrifugal switch 15, and capacitor 20 to the motor starting winding 3. Relay 13 then closes its contacts 22, 24, to energize the motor running winding 4. Opening of the centrifugal switch de-energizes the winding 3, but the relay 13 remains energized due to the engagement of contacts 22, 24, and the running winding circuit is maintained. The selector switch 37 is moved to engage contact 8 for reversing the motor so causing relay 13 to drop and close contacts 22, 27. The centrifugal switch remains open until the motor speed drops, the relay coil 10 remains de-energized, and the starting and running windings of the motor are interconnected in a loop circuit to provide braking operation. Closure of the centrifugal switch causes the energization of relay coil 10, closure of contacts 26, 28, and operation of reversing switch 19, so that the running winding is energized and the starting winding reversed. The opening of the centrifugal switch effects the disconnection of the starting winding but the energization of the coil 10 is maintained through the contacts 26, 28.

Abstract: 560,457. Cathode-ray tubes LUBSZYNSKI, H. G., and MILLER, H. July 25, 1942, No. 10425. [Class 39 (i)] In a cathode ray tube of the kind wherein electrons are projected from a gun 2 through a strong and substantially uniform magnetic field produced by a solenoid 9 surrounding the tube 1 to form a fasciculated electron beam and wherein deflection of the beam across the screen 6, which may be a mosaic screen, is effected by electrodes 3 disposed within the magnetic field, loss of focus of the beam due to changes in the strength of the electrostatic field between the electrodes is reduced by compensating-means which modify the motion of the electrons within the electrostatic deflecting field, the compensation being proportional to the strength of the electrostatic field. As shown, the electrodes 3 are energised in pushpull by a saw-tooth generator 12, shunted by a resistance 14 earthed at 13, and compensation is effected by a magnetic field set up by a solenoid 11 surrounding the tube and fed with current of a strength which is varied in accordance with the voltage between the electrodes 3. This normally requires that the current in the compensating solenoid should be of double the frequency of the generator 12. In another arrangement compensation is effected by varying the potential of the electrically neutral plane through the deflecting electrodes ; thus the earth connection 13 on the resistance 14 may be through a resistance traversed by a current derived from a frequency doubling arrangement fed from the generator 12. Specifications 542,219 and 542,497 are referred to.

Abstract: 1340266 Valves PROGRAMMELECTRONIC AG 22 April 1971 [5 Sept 1970] 10798/71 Heading F2V An electromagnet arranged between an electric motor and a burner valve controlled by the motor is adapted to allow closure of the valve if the power supply fails. As shown, initial rotation of crank 20 by motor 19 lowers frame 23 relative to valve stem 4a and lever 43 closes switch 42 allowing source 46 to energize coil 24 causing armatures 25 to engage stem 4a. Continued rotation of the crank 20 raises the frame relative to the stem 4a until armatures 25 abut the optionally adjustable head 26 of the stem, at which point the stem is raised to unseat valve member 2a against spring 5, the motor then being stopped by a switch operated by cam 30. Lever 43 remains in contact with the frame under magnetic attraction. If coil 24 is subsequently de-energized, as by opening of switch 45 in response to burner failure or switchoff, armatures 25 are free to be retracted by head 26 of the stem 4a as spring 5 closes the valve. In a modification, an electromagnet on a spindle reciprocable by an electric motor-driven cam retains a valve stem in abutment with the spindle. The cam operates a switch controlling the electromagnet, and a further switch opens upon release of the stem by the electromagnet.
