Abstract: 893,314. Monitoring photographic colour printing photo-electrically. ILFORD Ltd. Jan. 17, 1961 [Jan. 25, 1960], No. 2583/60. Class 40(3). A method of photographic colour printing comprises the steps of (a) inserting the negative 4 to be printed in an enlarger, (b) exposing anc processing a trial print 6 with an unexposed fixed out negative 10 in fron of photo-cells 15, 16, 17 sensitive to three primary colours, (c) replacing the negative 10 by the trial print, (d) adjusting the colour of the printing light using the colour modulator 2 until the meter 18 indicates that the light falling on cells 15, 16, 17 has the same composition as that previously passing through the negative 10 and (e) using the adjusted printing light to make the prints. The method depends upon the ratio of reflection density and transmission density of the print paper being equal to its colour contrast to reflected light. If this is not true either more or less than the indicated adjustment to modulator 2 is made. This also has to be done when the print is to be viewed by transmission and not reflection.

Filed: 1940-02-16
Abstract: 538,102. Dehydrating alcohol. CELEC CORPORATION, Ltd., and PHILLIPS, S. M. Feb. 16, 1940, No. 2991. [Classes 32 and 91] Concentrated alcohol (95 per cent.) is produced from wort by first removing the head products by distillation, rectifying the alcoholic wash, and then dehydrating the concentrated wash by contact with a saturated solution of a dehydrating compound, e.g. potassium carbonate, the de - hydrating compound being reused continuously by drawing off the diluted solution, evaporating off the absorbed water and recycling the re-concentrated solution. The alcohol thus obtained may be completely de-hydrated as described in Specification 534,374. Wort from a storage tank 1 is pumped through preheater 2 to the heads' still 3 where it is heated to 70‹C. to drive off aldehydes, acetone, formaldehyde, etc., through line 4 to condensers 5. The wash is then fed through line 7 to rectifying column 8 from which fusels oils are removed through lines 9, 10, while the alcoholic vapours pass to condensers 11, 12. The condensate is passed to a scrubber 13 where it flows in contact with the de-hydrating agent which is circulated through pre-heater 14, concentrator 15, cooler 16 and the scrubber 13. The de-hydrated alcohol which separates as a top layer in the scrubber 13 is fed to still 18 and thence as vapour to a de-hydration column 17 down which flow glycerol or glycols either pure or charged with de-hydrating agents, e.g. potassium carbonate acetate, or carbide, calcium chloride or carbonate, or sodium sulphate. The absolute alcohol passes off to a condenser 19 and collecting tank. The used glyceral is de-hydrated as described in Specification 534,374 by flowing it in film form over hot plates down a still 21 the vaporized alcohol and water being condensed in a condenser 22 from which alcohol is returned to base of column 8. The de-hydrated glycerol is returned to tank 25.

Filed: 1916-03-03
Abstract: 126,654. Skipwith, H. L. d'E., and Wall, T. F. March 3, 1916. Subaqueous audible signals.-Relates to submarine sound signalling-apparatus of the kind in which an electro-magnet energized by an alternating current effects the vibration of a diaphragm, and has for its object the provision of such a device which shall have a high power factor and which shall be controlled by a signalling key without injurious sparking taking place, either on closing or opening the key. According to the invention, the apparatus comprises an electro-magnet energized by an alternating current and in circuit with one or more condensers, a movable armature, and a vibrating diaphragm rigidly connected to the armature and secured at its periphery to a rigid support. In the construction shown in Fig. 1, the diaphragm G, the periphery of which is formed with a heavy flange secured to a support H, is connected to an armature C by a rod F. The armature is separated from the fixed core E of the magnetic circuit by an air gap D. The coils of the magnet are indicated at A. In a modification, Fig. 4, the coil A is mounted on brackets I, free from the vibrating parts, and two diaphragms G connected to vibrating armatures C are employed. In another modification, Fig. 5, in order to secure a symmetrical pull between the magnetic cores or armatures C, two sets of similar coils W1, W2, in parallel are provided, and two magnetic circuits separated by an air gap T. In order to diminish eddy currents, the flanks of the iron cores or armatures may be covered with a copper strip, or with thin metal laminµ J, Figs. 7 and 8, arranged in stepped formation. One or more condensers are arranged either in parallel or in series with the coils of the electromagnet. Various arrangements of the circuit to avoid sparking are shown in Figs. 12, 13, 15, and 17, in which B is the source of electricity, K a signalling key, S a condenser, R a resistance, and L the inductance. In Fig. 12 there are shown two condensers S1, S2, and the key K is arranged to short circuit one of them, the closing of the key causing the current to fall sufficiently low as to render the oscillator silent or nearly silent. As shown in Fig. 13, a resistance r is arranged in series with the key K which short circuits the only condenser S; a similar arrangement may be made with two condensers. The key K, Fig. 15, in. series with a resistance r, is arranged to short circuit the inductance L; and a resistance r, Fig. 17, is connected as a shunt to the combination of condenser and inductance. The oscillator is fixed to the side of a ship or is mounted in a body which will tow out and down from the fore and aft line of the ship as described in Specification 8117/15, [Class 113 (i), Ship and boat fittings &c.].
