Title: Improvements in or relating to infra-red thermal imaging systems
Inventor: GUILDFORD LESLIE HENRY
IPC: H04N5/33
Filed: 1968-02-15
Abstract: 1,216,548. Television; multiplex pulse signalling. MULLARD Ltd. 22 Jan., 1969 [15 Feb., 1968], No. 7572/68. Headings H4F and H4L. In a system for producing the thermal image of a scene in which the scene is scanned optically with a line array of infra-red detectors, the output of each detector is sampled and converted into time-modulated pulses which are combined in time division multiplex to form a video waveform which is used to reconstitute an image of the scene on a television monitor. The frame scan of the monitor is locked to that of the infrared optical scanner used with the detectors and the line time base of the monitor is synchronized with the sampling switch. General description.-As shown in Fig. 1, an infra-red detector 1 forming part of a row of such detectors supplies an output via amplifier 2 to a pulse position modulator 3 provided with a sawtooth waveform from a generator 4 controlled by a sampling pulse generator 5. A plurality of generators 5 are gated in succession by a units drift register 6 and each generator 5 controls a plurality of sawtooth generators 4, the outputs of the corresponding modulators 3, 3<SP>1</SP> &c. being fed in sequence by gates 7, controlled by tens shift register 8 followed by logic gates 9 controlled by hundreds shifts register 13, to a bistable circuit 11 which converts the position modulated pulses into width modulated pulses. The bi-stable is set by each clock pulse from generator 10 and reset by the next position modulated pulse a delay 12 compensating for propagation delay in the system. The pulses from bi-stable 11 may be amplified to a level which would constitute peak white and applied direct to a cathode-ray tube, thus producing picture elements of differing width on the screen. The output from generators 4 may be arranged to follow an exponential law so that low contrast signals are expanded and high contrast signals compressed. It may also be arranged to decrease the sweep rate of the sawtooth wave as by a switch so that areas of high contrast become expanded, the low contrast signals being gated out. Pulse modulation.-A voltage pulse V f , Fig. 6, supplied via R 1 , C 1 , L 1 , provides a sawtooth ramp of current for the tunnel diode TD 1  which causes it to conduct, the time at which it conducts being determined by the additional current flowing fron the signal source I SIG.  At the end of the pulse the energy stored in circuit L 1 , C 1 , R 1  causes a current overshoot which turns the diode off. The output pulse is differentiated at C 2 , R 2  to produce a position-modulated pulse. In a modification which improves the linearity, the output is filtered to reconstitute the original signal which is compared with the input signal, the amplified difference being applied as a correcting bias current to the tunnel diode.

Title: Improvements in the production of fats
IPC: C11C3/02
Filed: 1929-03-11
Abstract: 331,880. Hilditch, T. P. March 11, 1929. Esters.--Synthetic fats are praduced by esteri. fying a mixture of fatty acids containing about <1>/3 to <2>/3 of saturated fatty acids and the balance unsaturated acids, by heating with a deficiency of glycerol, and if desired under reduced pressure. A suitable mixture of fatty acids may be obtained by saponifying a vegetable fat or fats, and if necessary ruiding a proportion of animal fats or acids to adjust the content of saturated acids in the mixture to within the desired limits. In examples, a mixture containing specified proportions of palmitic, stearic, oleic, and linoleic acids yields on esterification a synthetic lard; a mixture containing palmitic and oleic acids (in which some of the oleic acid may be replaced by linoleic acid) gives on esterification a fat resembling natural lard; a fat resembling tallow is produced by esterifying a mixture of palmitic, stearic, and oleic acids, in which a part of the oleic acid may be replaced by linoleic acid; the fatty acids liberated from cacao butter are recombined with glycerol, to produce a product closely resembling mutton tallow. During the esterificafion an excess of about 10-20 per cent of fatty acid mixture is preferably employed, above that theoretically required in the reaction.
