Title: Improvements relating to curtain suspension devices
Inventor: HANKIN ROBERT WILLIAM
IPC: A47H1/144
Filed: 1958-10-21
Abstract: 870,188. Curtain suspension. SWISH PRODUCTS Ltd. Oct. 19, 1959 [Oct. 21, 1958; Sept. 25. 1959], Nos. 33519/58 and 32615/59. Class 52(5). In a curtain suspension device a nail engaging bracket 20 (Fig. 2) is provided with a depending shoe 202 capable of being engaged within a slot 211 in a rail 21 by an endwise sliding movement, the formation of the shoe 202 being such that the shoe has a self-locking relationship relatively to the rail 21 when the shoe has been engaged within the slot 211 so that the bracket 20 remains firmly held in whatever position it may occupy relatively to the rail when release of the bracket by the manipulator takes place. The shoe 202 has a central thickened portion 203 which tapers at the end to wafer edges. The effective maximum thickness of the portion 203 when unstressed is greater than the depth of the slot 211. In a modification shown in Fig. 10 a pair of shoes 202 are provided to engage channels 216.

Title: Improvements in or relating to cathode ray tubes
Inventor: GABOR DENNIS
IPC: H01J31/12
Filed: 1955-11-23
Abstract: 842,973. Cathode-ray tubes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 16, 1956 [Nov. 23, 1955], No. 33613/55. Class 39(1). In a " flat " cathode-ray tube such as described in Specification 739,496, the electron valve for charging and discharging the array of conductors consists of an electron gun 7, Fig. 3, a collector electrode 8, a secondary electron collector 115 associated with the region EF of the array, a secondary electron suppressor electrode 105 associated with the region CD, and a pair of deflecting electrodes 26, 26<SP>1</SP>. During the charging process electrodes 26, 26<SP>1</SP> deflect the beam on to the region EF so that the potential of the array rises to that of electrode 115. In the discharging process the electron beam is directed to collector electrode 8, but at the top of the array an electrode permanently at low potential deflects a portion of the beam towards region CD of the array. Since region CD is off-set with respect to region AB a transverse electrostatic field between regions AB and CD runs down the array until the whole of the beam falls on region CD and the array is discharged. Region E-F may be coated with fluorescent powder or magnesium oxide smoke to enhance the secondary emission. In other embodiments, the charging of the array may be effected by providing a conductive connection between the array and a source of charging potential. In Fig. 5, a photo-conductive layer 121 provides the connection between electrode 122 and the array E F when it is illuminated by the beam C falling on a fluorescent screen 119. An aluminium layer 12 covers the fluorescent screen 119. A similar photo-conductive layer 121<SP>1</SP> and fluorescent screen 119<SP>1</SP> may be used for discharging the array. Phosphors fluorescing in the ultra-violet region are preferably used for the screens 119, 119<SP>1</SP>. A further modification is referred to in which layers directly influenced by electron bombardment are used.

Title: A process for preparing liquids containing active principles or hormones from parathyroid glands
IPC: A61K38/22
Filed: 1930-11-10
Abstract: A substance having the property of inhibiting the growth of tissues is obtained from parathyroid glands by neutralizing an acid extract of the glands to a pH of 4,6 to 5,0, filtering off the insoluble matters precipitated and treating the filtrate to concentrate or purify the hormone therein.  The filtrate may be concentrated under reduced pressure the pH being readjusted if necessary to 4,5 to 5,0. The acid liquid may consist of water, an alcohol, e.g. ethyl alcohol, or a ketone, e.g. acetone, and an acid, e.g. sulphuric or hydrochloric acid.  The fat may be extracted by treatment of the glands with a fat solvent prior to or simultaneously with treatment with the acid liquid.  Examples: (1) Minced glands are shaken with a mixture of water, sulphuric acid, alcohol, and benzene; strained off and the benzene separated.  The acid alcoholic liquid is neutralized with caustic soda to pH 4,8.  Alcohol is added to precipitate sodium sulphate and the liquid after filtration is concentrated in vacuo, and the pH adjusted to 4,8.  (2) Glands are shaken with strong alcohol containing 5 per cent concentrated sulphuric acid, the liquid is neutralized till slightly acid to litmus, filtered, and concentrated by distillation and adjusted to pH=4,8, (3) Glands are treated on a boiling water bath with dilute sulphuric acid, the liquid is cooled and the fat separated and its pH adjusted to pH=9 by addition of sodium hydroxide, strained and centrifuged. The liquid is then neutralized with sulphuric acid to pH=4,8, allowed to stand in the cold and centrifuged.  The precipitate so obtained is dissolved in dilute alkali, the pH adjusted to pH=4,8, centrifuged and the filtrate added to that first obtained.  Alcohol is added to precipitate sodium sulphate and the filtrate concentrated.  (4) Glands are macerated with acetone, and the solid residue is dried, ground and treated with dilute sulphuric acid.  The solution obtained is treated in a similar manner to that of example 3.

Title: Improvements in thermionic valves
IPC: H01J21/20
Filed: 1927-12-19
Abstract: 307,558. Midgley, A. H. Dec. 19, 1927. Vacuum tubes.-A multiple valve has a cathode of U, V, or M-shape, a power-amplification electrode system consisting of an anode and one or more grids being associated with the central part of the filament, and an electrode system for detection or low-power amplification being associated with the two adjacent ends of the filament, the electrode systems being so disposed that interaction between them is negligible. As shown in Fig. 1, the cathode 1 is surrounded by a grid 5 and an anode 4, both being preferably of flattened cylindrical shape. The detector or low-power amplification stage consists of an anode 6 in the form of a rod or plate, and a grid 7, both mounted between the ends of the filament. The grids do not extend beyond the ends of the corresponding anodes, thereby avoiding interaction. The grid 5 may be connected with the anode 6 either directly or through a blocking condenser which may be mounted within the envelope. In a modification two electrode stages may be associated with the adjacent ends of the filament, one stage with each end. Thus the anodes may consist of flat or curved plates arranged outside or within the ends of the filament, and the grids may be arranged between the filament and anodes or around the filament; interaction between these sets of electrodes may be produced as described in Specification 280,981, while avoiding interaction with the electrodes of the high-power stage.
