Title: Improvements in or relating to mountings for periscopic sextants
Inventor: EVERITT PHILIP FRANCIS
IPC: G02B23/08
Filed: 1948-10-05
Abstract: 653,716. Mounting sextants and periscopes on aircraft and submarines. KELVIN & HUGHES, Ltd. Oct. 5, 1948, Nos. 25908/48 and 25362/49. [Classes 4 and 113 (ii)] A hatch for housing a periscopic sextant in the fuselage of an aircraft, or a periscope in a submarine, comprises a guideway for the reception of the instrument, a hatch cover which is normally closed, means for locking the hatch cover in the closed position, means whereby the instrument can be inserted in the guideway only to an intermediate position when the cover is closed, in which position, however, the locking means is held in the unlocked position so that the cover can be opened and the instrument pushed along the guideway to an operative position. As shown in Figs. 1, 2 and 4, the guideway 42 is provided with a pressure-tight cover 18 constructed and operated as described in Specification 652,199, [Group XXIV]. When the cover is closed the periscope tube 10 can be pushed only into a position in which a circumferential groove 12 is engaged by hand-operated pawls 52 in a casing 50 and a further pawl 60 actuated by a hand lever 34 by which the cover 18 is opened. Engagement of the pawl 60 in the recess 12 releases a sliding block 55 connected by a cable 40 to a press-button 37 on the lever 34, and upon pressing the button prior to opening the cover, the block 55 is moved to release a second pawl 63 which enters the groove 12. The pawl 60 is rounded on its upper and lower surfaces so that when engaged in either of the grooves 12 or 13 it does not prevent vertical movement of the instrument in either direction, but the pawl 63 is rounded only on its lower surface, so that when engaged in the groove 12 the instrument can be raised but not lowered. When the cover 18 has been opened by the lever 34, the instrument can be raised to the position in which the pawls 52, 60 engage the lower groove 13, which is too narrow to permit entry of the pawl 63. The instrument can be lowered after the pawls 52 have been retracted. In the form shown in Fig. 5, the cover-operating handle 70 is pivotally mounted and is normally locked by a spring-loaded pin 72 in a casing 71. To open the cover a button 155 is rotated about the longitudinal axis of the handle, thereby turning an axial rod 81 provided with a projection which forces a pin 74 outwardly, the latter in turn pressing the pin 72 out of engagement with the handle 70 which can then be rotated to open the hatch cover. If the instrument is not positioned correctly, the projection on the rod 81 cannot operate the pin 74. A single finger-operated pawl 154 replaces the pawls 54 of the former arrangement. A cam-operated pawl 75 is urged by a spring 79 to engage the groove 12 when the lever 70 is moved to open the hatch, but is retracted by a button 76 when the lever is moved to close the hatch.

Title: Improvements in or relating to light-electric translating means and to television transmitters
IPC: H04N5/30
Filed: 1936-09-24
Abstract: 482,208. Light - sensitive cells ; cathode - ray amplifiers ; television. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Sept. 24, 1936, No. 25993. Convention date, Sept. 24, 1935. [Classes 39 (i), 40 (iii), and 40 (v)] A light-sensitive cell depends upon the aetino-dielectric effect and comprises a plate electrode 11, Fig. 1, a mesh electrode 12 permeable to light, and a layer 10 of phosphorus having a dielectric constant which varies according to the strength of the illumination incident upon it. For amplification the cell forms one arm of a capacity bridge, one diagonal of which comprises an oscillator 16 while the other diagonal comprises a cathode-ray amplifier 18. The cathode stream 5 oscillates with an amplitude that depends on the illumination of the cell 10, 11, 12, and the electron current passing through an apertured diaphragm 21 varies correspondingly. Amplifying means of the electron-multiplier type, operating by secondary emission, may be provided in the part 6 of the tube. In a television transmitter, Figs. 2 and 3, the picture is projected line by line, by means of a mirror wheel upon a strip 24 of phosphorus which forms part of the dielectric that separates the electrodes 22, 23. A cathode beam 25 is traversed in a direction parallel to the arrows Q by deflecting-plates (not shown) in a perpendicular direction, and is at the same time oscillated along the arrows P, by the voltage applied to plates 22,23 by the oscillator 16. The amplitude of the latter oscillation depends on the dielectric constant at each point x of the layer 24, and the electron current passing through a slit 26 in a diaphragm, which varies accordingly and may act upon electron - multiplying means, serves as picture current for the television transmitter.

Title: Method of igniting an electric discharge tube
IPC: H05B41/232
Filed: 1932-09-19
Abstract: 390,729. Discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Sept. 19, 1932, No. 26014. Convention date, Nov. 25, 1931. [Class 39 (i).] A gas-or vapour-filled discharge tube with an incandescent cathode heated by current led through the cathode or through an adjacent heater, is ignited by heating the cathode initially above its normal working temperature. The voltage applied to the electrodes is lower than the ignition voltage with the cathode at its normal temperature but is sufficient to start the discharge with the cathode temporarily overheated. The cathode of a sodium-filled lamp may be supplied from a secondary of an autotransformer itself in series with a resistance in the discharge circuit so that the heating voltage is above normal for sufficient time to overheat the cathode, but drops when the discharge starts. In a modification, the cathode 2 is supplied from a secondary 14 of a leakage transformer 9 having a shunting leg 15 with an air gap 16.

Title: High vacuum distillation
IPC: B01D1/22
Filed: 1939-09-16
Abstract: 532,770. High vacuum distillation. DISTILLATION PRODUCTS, Inc. Sept. 16, 1939, No. 26016. Convention date, Sept. 28, 1938. [Class 32] A process of high vacuum distillation comprises distilling an organic substance in the form of a thin film from a heated vaporizing surface across a substantially unobstructed space, the pressure of the distilland vapour being less than 0.001 mm. Hg. and the distance separating vaporizing and condensing surfaces being at least three times as great as the mean free path of the distilling molecules. The deleterious effect of any deposition of solids on the condensing surface may be reduced by the use of a condensing surface of substantially greater surface area than that of the vaporizing surface, and a scraping or mechanical distributing device may be accommodated in the space between the evaporating and condensing surfaces. For distilling vitamins from fish oils, temperatures of 90-275C., and particularly 120-250C., are suitable, and pressures of residual gas of less than 0.1 mm. Hg., preferably 0.01-0001 mm. Hg., should be employed.

Title: Manufacture of new monoazo-dyestuffs
IPC: C09B43/124
Filed: 1947-09-25
Abstract: Monoazo dyestuffs are manufactured by coupling a diazotized 4-nitro-6-acylamino-2-aminophenol with a hydroxybenzene containing an aliphatic hydrocarbon in p-position to the hydroxy group, advantageously in an alkaline medium, if desired with the addition of a neutral or basic solvent (e.g. alcohol, pyridine or ethanolamine), or by reducing a dyestuff obtained similarly from diazotized 4 : 6-dinitro-2-aminophenol (e.g. by means of an alkali sulphide or hydrosulphide) so as to convert the nitro group in o-position to the hydroxy group into an amino group, which is then acylated (e.g. by means of an acid halide or anhydride).  In either case the acyl residue may be aromatic or especially aliphatic, examples being formyl, acetyl, oxalyl, sulphobenzyl and phthalyl.  The products may be used for dyeing or printing various fibres, especially those of animal origin such as wool, silk or leather.  They may be treated in substance, in the dye bath or on the fibre with agents yielding metal, e.g. chromium.  In examples: (1) 4 - nitro - 6 - acetylamino - 2 - aminophenol is diazotized and coupled with p-cresol in the presence of sodium hydroxide and pyridine; (2) the sodium salt of the dyestuff 4 : 6 - dinitro - 2 - aminophenol --> p - cresol is warmed with sodium hydrosulphide and sodium hydroxide in water and the product is heated with acetic anhydride; (3) and (4) wool is dyed brown with the product of (1) by the afterchrome and single bath chroming processes. Additional coupling components specified are 4-isopropyl-, 2 : 4- and 3 : 4-dimethyl- and 2-acetylamino - 4 - methyl - phenol. Specification 637,404 is referred to.  Samples have been furnished under Sect. 2 (5) of the dyestuffs obtained by coupling diazotized 4 - nitro - 6 - acetylamino - 2 - aminophenol with (I) 1 : 2-dimethyl-4-hydroxybenzene (in an aqueous suspension of calcium hydroxide); (II) p-tert.-amylphenol; and (III) p-sec.-butylphenol.  The Specification as open to inspection under Sect. 91 comprises also the use as diazo components of 6-nitro-4-acylamino-2-aminophenols and as coupling components of other hydroxybenzenes coupling in o-position to the hydroxy group, e.g. 4-acetylamino-3-methyl-, 4-acetylamino-3 : 5-dimethyl- and 4-chloro-phenol.  This subject-matter does not appear in the Specification as accepted.
