Title: Improvements in or relating to cathode ray tubes and circuits therefor
IPC: H01J29/62
Filed: 1935-01-12
Abstract: 455,084. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Jan. 12, 1935, No. 1085. Convention date, Jan. 12, 1934. [Class 39 (i)] In cathode-ray tubes, preferably highly evacuated, television tubes, an apertured diaphragm 4 is provided between the cathode 2 and the electron-optical system for producing sharp image points on the image screen 5 and a tubular electrode 6 is placed close to the diaphragm 4 at the side remote from the cathode. The electrodes 4, 6 are insulated so that they operate at different potentials and the diameter of the tube 6 is so large compared with the diameter of the aperture in the diaphragm 4 that the final image on the screen 5 is not affected by raising the diaphragm 4 to a potential of several hundreds to a thousand volts above that of the tube 6. The diaphragm 4 may thus be maintained at a high potential to produce adequate emission from the cathode 2. The final anode 7 is tubular with the same diameter as the tube 6 and forms with the tube 6 a lens reproducing the aperture of the diaphragm 4 on the screen 5. The diaphragm aperture may be directly opposed to the cathode 2 at a sufficient distance therefrom, for example, 3-5 mm. or 10 per cent of the length of the tube 6 to avoid reproduction of the cathode surface on the screen 5 simultaneously with reproduction of the aperture. Alternatively, the aperture may be supplied with a parallel beam of electrons by a preliminary concentrating system 9 arranged as shown and including a control electrode 8. The field between the electrodes 4, 6 does not disturb the focusing by the electrodes 6, 7, but does refract marginal rays to reduce secondary light outside the image point on the screen 5. The aperture in the diaphragm 4 may be 0À3 mm. in diameter and <1>/20 -< 1> /30 of the diameter of the tube 6 which need not be of circular crosssection. The tube 7 is 2-3 cms. long and terminates in a diaphragm 7<1> with an aperture smaller than the minimum distance apart of the pair of deflecting plates adjacent to the tube 7 to avoid interference with the lens field by the deflecting fields. The diaphragm 4 may be connected as shown to the anode 7 or may be maintained at adjustable potential by connection to a tapping on a potentiometer between the electrodes 2, 7, the tube 6 being then connected to a fixed-resistance potentialdivider within the cathode-ray tube. The tubes 6, 7 may be at 300 and 1500-2000 volts respectively, details being specified. In applying the invention to a tube with a flat stream of electrons deflected transversely relatively to an anode as for amplifying purposes, the tube 6 is replaced by a pair of plates which may be laterally united to form a box, and the distance apart of these plates is large compared with the breadth of the aperture in the diaphragm 4. Specifications 417,850, 420,667, 442,511, and 442,724 are referred to.

Filed: 1925-01-13
Abstract: 250,340. Holman, J. L., and Holman, A. T. Jan. 13, 1925. Percussive tools.-The anvil block 3 of a rock drill or like tool is formed with an open passage such as a flat 4 whereby motive fluid may leak from one side of the block to the other. An exhaust port 5 is arranged to allow such fluid to escape, the port being formed between the chuck sleeve 6 and a cylinder bush 7. Water which may accumulate in front of the anvil block can also escape by the port 5, to which the main cylinder exhaust may also be led by a suitable conduit.

Title: Concentric tube structure
IPC: F28F9/013
Filed: 1962-01-12
Abstract: 921,281. Cooling reactors. ATOMIC ENERGY OF CANADA Ltd. Jan. 12, 1962 [Feb. 9, 1961], No. 1264/62. Class 39 (4). [Also in Group XXVIII] A calandria tube 1 of a nuclear reactor is mounted concentrically around a pressure tube 2 and spaced therefrom by an endless helical spring 4 which is freely seated between the tubes, i.e. it is unattached to either tube, whereby it permits axial movement of the tube 2 relative to the tube 1 by a rolling movement relative to the tube walls. Where, for example, the tube 1 is of aluminium and the tube 2 spring 4 of a zirconium alloy, the rolling movement of the spring will wear a seat for itself in the tube 1 and thus provide a positive locating means. The spring 4 provides a substantially uninterrupted annular space 3 between the tubes for the passage of cooling and purging gas while at the same time offering limited neutron absorption.

Patent GB-596392-A (GB)
Title: Improvements in high vacuum unobstructed path fractionating process and apparatus
IPC: B01D3/30
Filed: 1945-01-17
Abstract: <PICT:0596392/III/1> <PICT:0596392/III/2> In high vacuum fractional distillation processes the vapours to be rectified are passed through an unobstructed space between an outer, stationary, heated surface and an inner condensing surface, and condensate is conveyed preferably by centrifugal force, from the condensing to the heated surface in a direction across the vapour flow.  The liquid to be fractionated is introduced into the lower portion of an electrically-heated and insulated vessel 6, Fig. 1, which is then closed by cap 8 and evacuated via conduit 10.  Agitation is effected by cone 28 which is rotated by means of shaft 12 and pulley 18. Shaft 12 is cooled by fluid, introduced through conduit 20, and carries a spiral 26. The vapours evolved from the liquid are condensed on spiral 26 and shaft 12, and the condensate is thrown by centrifugal force on to heated wall 6 where it is reheated as it flows down in a thin film.  There is thus a number of condensations and re-evaporations during the passage of the vapours through the column, and this number can be varied by the amount of cooling applied.  The rectified vapours are condensed by cooling coils 9, collected in gutter 22, and withdrawn through conduit 24.  Fig. 2 shows a gas-heated, self-compensating still in which cylinder 34 and vessel 6 define an annular space 36 which, during distillation, is filled with hot vapours.  Condensate is flung from rotating discs 27 on to wall 34 and re-vaporized by the latent heat given up by the vapours in space 36.  A modification is also described in which the condensing surface is independent of the agitator shaft, and another in which condensate is conveyed to the heated surface by stationary means.

Title: Process for the preparation of active glucosides of senna
IPC: C07H15/244
Filed: 1942-02-06
Abstract: 555,450. Glucosides of senna. SANDOZ, Ltd. Feb. 6, 1942, No. 1599. Convention date, May 13, 1941. [Class 2 (iii)] Glucosides are extracted from senna leaves and pods by a process which comprises making an alcoholic extract and treating this with an alcohol soluble alkaline-earth metal salt and adding basic substances until neutral or nearly neutral, or treating the extract with an alcoholsoluble basic alkaline earth metal derivative, separating the precipitated alkaline earth salt of the glucoside, and liberating the free glucosides by treatment with an acid. By the above treatment two glucosides which are described as Sennoside A and Sennoside B are obtained. These differ greatly in their solubility in methyl alcohol by means of which they may be separated. The glucosides may be purified by recrystallization from methyl alcohol or a mono-ether of a glycol. Both the above glucosides are acidic in nature and form salts. In examples (1) Senna leaves are extracted with benzene containing a little methyl alcohol to remove resins etc., and then with methyl alcohol. To the alcoholic extract an alcohol solution of calcium chloride is added followed by methyl alcoholic ammonia. The precipitated salts are. filtered, suspended in methanol and mixed with gluconic acid, heated to 40‹C. and filtered, the insoluble part containing Sennoside A remaining behind. Sennoside B crystallizes from the filtrate. Sennoside A is isolated from the.insoluble portion by treatment of a methanol suspension with ammonia, filtration of the calcium gluconate and isolation of Sennoside A by pouring into a hydrobromic acid solution of methanol. (2) Senna leaves or pods are extracted with aqueous acetone containing sodium carbonate, the extract neutralized with acetic acid and evaporated to dryness. A methanol solution of the product is treated with hydrobromic acid, and the liberated glucosides are precipitated in the form of their salts with barium bromide which precipitate is then worked up as in example (1).
