Title: Improvements in or relating to radar systems
IPC: G01S7/06
Filed: 1948-02-27
Abstract: 655,627. Radiolocation. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948, No. 5933. Convention date, Jan. 11, 1944. [Class 40 (vii)] A pulse radar system comprises in addition to the main cathoderay display arrangement, which as described is a B-scope, a C- scope display which is adapted to display only those echo signals received from reflecting objects situated within a selectable band of ranges. Pulses from a blocking oscillator 1 are applied through unit 2, fixed delay line 6 and units 15, 16 and 17 to the modulator and transmitter 18 and thence to the aerial system 21. Pulses from the delay line 6 are also applied to the variable delay line 8 which triggers units 10 and 11 to apply to receiver 12 a sensitizing pulse which commences a short interval after pulse transmission and lasts a sufficient length of time to enable the receiver to receive signals from the maximum range desired. The aerial system 21 scans in azimuth and elevation and controls azimuth potentiometer 33 and elevation potentiometer 49 according to its instantaneous directivity. Output from the azimuth potentiometer 33 is applied to the B-scope, which, in an airborne radar system, is used as the radar operator's display. The range scale of the B-scope is synchronized by pulses from the oscillator 1 which are applied to units 25, 26 and 27 to develop suitable time-base voltages. By virtue of the delay line 6, the time-base may be arranged to commence at the instant of pulse transmission and need not be delayed with respect thereto. Range-marking pulses from unit 30 are applied to the first grid of the B-scope and the output of the receiver 12 is applied to the cathode thereof. For the control of the C- scope, which in the example given is the pilot's display, pulses from the oscillator 1 are applied to unit 35 which is a multivibrator or an alternative form of variable delay device. The delayed pulses therefrom are applied to a further multivibrator 40 which delivers a rectangular gate pulse of variable duration and timing to gate the amplifier 46 which applies the amplified output from the receiver 12 to the C-scope. The deflection of the cathode-ray beam of the C-scope is controlled by the potentiometers 33 and 49. The trailing edge of pulse from 40 is applied to cathode follower 38 where it is mixed with the output of 35 to produce a pair of pulses which are applied to the B-scope marking the beginning and the end of the C-scope gating interval.

Title: Process and apparatus for the hydrolytic decomposition of fatty oils and fats
IPC: C11C1/04
Filed: 1949-03-07
Abstract: <PICT:0666785/III/1> Fats and fatty oils are hydrolyzed to yield fatty acids and glycerine by treatment in the liquid phase with water at a temperature between 240 and 295 DEG C. and at a pressure between 110 and 180 Kg. per sq. cm. in the absence of a hydrolysis catalyst. Hydrolysis may be substantially complete in 10-15 minutes and the glycerine solution obtained may have a strength in excess of 30 per cent.  The hydrolysis may be effected during passage of the compressed mixture of water and oil (e.g. neutral or acid palm oil or neutral colza oil) through a heated tube which is preferably horizontal.  The mixture of reaction products issuing from the tube is cooled and the pressure released.  Thereupon the mixture is separated into its components by settling or centrifuging.  In the Figure, two hydrolysis tubes 5 and 6 are employed, reaction products from tube 5 are fed to settling column 9 and reaction products from tube 6 are fed to settling column 10.  Fatty material to be hydrolyzed is drawn from storage tank 1 and fed, together with glycerine water drawn from the lower part of column 10, into tube 5. Water is drawn from storage tank 3 and fed, together with partially hydrolyzed fatty material drawn from the upper part of column 9, into tube 6.  Fatty acids drawn from the upper part of column 10 and glycerine water drawn from the lower part of column 9 are stored in tanks 2 and 4 respectively.  If it is desired to obtain a lower degree of hydrolysis or if highly acid oils are used as starting materials, it is only necessary to effect the hydrolysis in a single stage and in this case only the tube 5 and the column 9 are used. Whether one or two stages are employed, hydrolysis is carried out in a continuous manner.

Title: The manufacture of softening agents for textile goods containing artificial silk
IPC: D06M13/256
Filed: 1931-02-27
Abstract: As softening agents for textile goods containing artificial silk, use is made of mixtures of water-insoluble saturated fatty acid amides or N-substitution products thereof (other than N-hydroxyalkyl substitution products) with sulphonic acids or sulphuric esters derived from hydroxylated paraffin derivatives containing from 12 to about 30 carbon atoms and about one hydroxyl group.  The softening agents may be prepared by mixing the components directly, an excess of the sulphonic acid or sulphuric ester component being preferably used.  Alternatively, the fatty acid amide or substituted amide may be added to the hydroxylated paraffin derivative prior to the sulphonation of the latter, whereafter sulphonation is effected with a sufficiently restricted proportion of sulphonating agent and/or at a sufficiently low temperature to avoid sulphonation of the amide. In the examples, (1) a sulphonated product is prepared by heating a trichlorinated paraffin with aqueous caustic soda under pressure, as described in Specification 343,948, and treating the product with chlorsulphonic acid, as described in Specification 344,829; an aqueous paste of this sulphonated product is mixed with palmitic amide, and the mixtue is warmed; instead of palmitic amide its N-monoethyl, N-cyclohexyl, and N-benzyl derivatives may be used; (2) the sodium salt of the sulphuric ester of lauryl alcohol is mixed with stearic amide and water, and the mixture is warmed; (3) a mixture of lauryl alcohol and palmitic amide is sulphonated in trichlorethylene to produce a mixture of unsulphonated palmitic amide with the sulphuric ester of lauryl alcohol; instead of lauryl alcohol a mixture of cetyl and oleyl alcohols may be used. The softening agents may be added to the finishing bath or the dye bath. Specification 328,675, [Class 2 (iii), Dyes &c.], also is referred to.
