Title: Method and apparatus for the speedy manufacture of soap
IPC: C11D13/02
Filed: 1946-01-02
Abstract: <PICT:0605653/III/1> Soap is rapidly produced by transforming a mixture of fatty substances and an aqueous alkaline solution in the cold into a very fine emulsion by mechanical means, stirring being maintained after saponification so as to avoid solidification and to allow the whole reaction to take place in the emulsifying apparatus itself and the soap to be easily discharged therefrom.  A suitable plant comprises a jacketed vat 2 with stirrer 7, one or more pumps 1, and a tubular column 8 producing the pressure required for the pumps, the parts being arranged in a closed circuit.  The jacket is sub-divided by a partition 4 into a steam jacketed section 5 and a cold water jacketed section 6.  In operation, the fatty substances are supplied to the vat and melted therein by admission of steam to the jacket section 5; the alkaline lye is then added in slight excess to that required for saponification of the fatty substances and the stirrer operated; the pump is now started and both pump and stirrer are operated together until the charge thickens.  The pump and stirrer are stopped at this stage, and the steam being cut-off from the jacket section 5, cold water is supplied to the jacket section 6. After a short period of rest, the soap mass formed is again pumped and stirred for a few passages around the circuit to complete the saponification, avoid solidification, &c.

Title: Cathode ray oscilloscope
Inventor: HORNAK TOMAS
IPC: G01R13/34
Filed: 1966-01-04
Abstract: 1,087,211. Cathode - ray oscilloscopes. VYZKUMNY USTAV MATEMATICKYCH STROJU. Jan. 4, 1966, No. 289/66. Heading H4T. In a sampling oscilloscope one co-ordinate deflection is produced by pulses, the amplitudes of which are proportional to the difference in time between the occurrence of two predetermined amplitude levels in each cycle of a recurrent A.C. waveform to be examined whilst the other co-ordinate deflection is produced by a sawtooth voltage having a recurrence period long with respect to that of the A.C. waveform. If the latter comprises an (theoretical) impulse of infinite slope, the time difference will be identical during each cycle and the resulting trace will be a vertical line-i.e. a replica of the impulse. The invention therefore provides an effective sampling pulse of zero width. Referring to Fig. 3, the A.C. waveform is supplied to one input of each of a pair of amplitude comparators 2, 3, the other inputs of which are respectively supplied with the output of the relatively long recurrence period sawtooth generator 5-also applied to the vertical deflection plates 11- and the output of a D.C. reference generator 7. The latter is adjusted by attenuator means 6 to correspond to an instantaneous amplitude along the rise time portion of the A.C. waveform and the maximum-to-minimum range of the sawtooth is adjusted by attenuator means 4 to encompass the whole (or any desired fraction) of the amplitude range of the rise time interval. The comparators-which may utilize the circuitry, Figs. 8, 10 or 11 (not shown)-each supply an output when a predetermined relationship occurs between the two inputs thereto. Such outputs are then utilized in means 8-also Fig. 12 (not shown)-to produce pulses the amplitudes of which are proportional to the time interval between the occurrences of such outputs and these pulses are supplied to the horizontal deflection plates 9. The use of the arrangement of Fig. 3 to measure the intervals between the rise time portions of two A.C. waveforms of the same recurrence frequency is explained and modifications suitable for simultaneously displaying the rise time characteristics of three such A.C. waveforms is described with reference to Figs. 6 and 7 (not shown). A switchable predetermined delay element is included in the means 8 to enable the time-base-horizontal deflection-to be calibrated (Fig. 12, not shown).

Abstract: 540,444. Colour photography and sensitive material therefor. KODAK, Ltd. (Eastman Kodak, Co.). Jan. 11, 1940, No. 622. [Class 98 (ii)] Material suitable for making subtractive prints comprises a support, as of paper, glass, synthetic resin, a cellulose ester, or a metal such as aluminium, carrying a mixed grain emulsion layer consisting of grains sensitive only to blue, grains sensitized also for green, and grains sensitized also for red, the inherent blue speed of the firstmentioned grains being at least 10 times that of the green and red sensitized grains, preferably 20 times and even as much as 50 times. Alternatively, the support may carry one mixed grain emulsion layer containing fast grains sensitive only to blue and slow grains sensitized also for green or red, and another emulsion layer, e.g. on the opposite side, containing slow grains sensitized also for the third colour. The material either carries also a de-colourisable filter layer as of tartrazine, or is exposed through a separate such filter layer, which is so chosen that it passes light of a colour to which the printing speed of the grains sensitive only to blue is substantially the same as that of the silver halide grains sensitized to green and red, and at the same time reduces the effective speed to blue light of the slow grains :almost to zero, so that they record susbstantially no blue light. The emulsions are of silver bromide, or preferably silver bromo-iodide. The blue-recording emulsion may be of the kind used for motion-picture negative or press film. The other emulsions may be of the kind used for positive films or enlarging papers; one may be sensitized for red with an 8-alkyl or 8-phenyl-3, 4, 31, 41 dibenzthiacarbocyanine dye, and another sensitized for green with a thia- or selena-21- cyanine dye or a 3, 4-benzthia-2<SP>1</SP>-cyanine dye. Colour couplers, e.g. those having a methylene group or phenolic hydroxyl group reactive in the coupling process, may be incorporated in the emulsions, but are preferably in three separate developing solutions, which may contain as colour forming developing agent a primary aromatic annine such as diethyl-p-phenylene diamine. The images may also be processed by image-wise oxidation of leuco dyes, e.g. as described in Specifications 521,746, 521,833, 521,834 and 521,888. The procedure described in Specifications 540,451 and 540,464 may be adopted to minimize wandering of the sensitizing dyes. Specifications 468,560, 478,933, 500,611, 516,536, 524,552 and 532,098 and Specification 37402/38 (as open to inspection under Sect. 91) also are referred to.
