Abstract: 433,635. Horticultural frames. WALFORD, R. SCOTT-, Mitre Works, Battle, Sussex. Feb. 19,1934, No. 5462. [Class 20 (i)] The roof of a plant shelter comprises a plurality of sections 22, 23, 24, at least one of which can slide into overlapping relationship with an adjacent section, the sliding section being supported on the shelter through the medium of a laterally extending flange or like projection. In the construction shown, all three sections are slidable. The shelter comprises four detachably connected walls 10-13 each consisting of an open frame built of angle-bars 15. To the upper bar of the side walls, a strip 32 having grooved portions 31, 34 is secured. These grooves slidably receive the downturned flanges of the upper T-section bars of the sliding roof sections. The end sections 23, 24 slide in the groove 31 and the lower angle-section bars thereof slide on the upper glazing bar of the front wall. The middle section 22 slides in the groove 34 and its lower bar 28, which is of T-section, is similarly supported on the front wall. The sections may be slidden off the shelter or they may be removed by lifting them to a horizontal position by handles 36 and withdrawing them horizontally. The strip 32 may have a rain shield formed integrally therewith, as shown, or a rain shield may be detachably secured thereto. The walls of the shelter are protected by bars 20. The structure may be extended by removing the rear wall and securing a further pair of end walls to the shelter, as shown in dotted lines in Fig. 2. These extensions are interconnected by a wall similar to the wall 10, and the latter supports the lower ends of additional sliding roof sections.

Abstract: 854,818. Separating neptunium and plutonium from uranium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 16, 1943 [April 30, 1942], No. 5864/42. Class 39(4). Neptunium and plutonium are separated from a uranium salt by dissolving the salt in an organic solvent and then treating the solution with an agent which removes most of the substances other than the uranium salt. Uranyl nitrate, which has been irradiated with slow neutrons (or prepared from a uranium compound so irradiated), is dissolved in methyl ethyl ketone, acetone, ethyl alcohol, methyl alcohol, ether, or cyclohexanone and is then treated (a) with dehydrated charcoal, barium sulphate, or titanium oxide, on to which the neptunium is absorbed and may be removed with hot 10% sulphuric acid ; or (b) with xylene, benzene, toluene, cymene, tetraline, chlorobenzene, nitrobenzene, or carbon tetrachloride, when a small aqueous layer containing the neptunium is formed ; a small amount of water or an aqueous solution of ammonium nitrate may be added, together with sodium sulphite as a reducing agent. Neptunium may be concentrated in the aqueous solution by adding a reducing agent and ferric chloride, followed by ammonium hydroxide and ammonium carbonate to form a ferric hydroxide precipitate which carries down the neptunium. The precipitate is then connected into chlorides and neptunium separated (a) by distilling in a stream of hydrochloric acid and chlorine when the less volatile neptunium chloride remains behind ; or (b) by extracting a concentrated aqueous solution of the chlorides with ether containing hydrochloric acid, when the neptunium is left in the aqueous layer.

Title: Improvements relating to variable gain transistor amplifiers

IPC: H03G1/00
Filed: 1962-02-17
Abstract: 1,028,332. Transistor amplifiers. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 15, 1963 [Feb. 17, 1962], No. 6411/62. Heading H3T. A variable gain transistor amplifier, for example an intermediate-frequency amplifier in radar equipment, comprises a common emitter transistor stage whose output is coupled to the input of a common-base transistor stage, means being provided for controlling the gain of the common-emitter stage. Since the common-base stage has a low input impedance, variations in the comparatively high output impedance of the common-emitter stage as its gain is varied do not substantially affect the characteristics of the common-base stage. In the arrangement shown, the gain of the common-emitter stage TR1 may be varied by varying the D.C. bias applied to the base of the transistor from potentiometer Rv. The control may be arranged to be due either to the varying emitter-current level or to the varying collector-voltage level with base bias. The emitter input impedance to common-base transistor TR2 exhibits an inductive component which is tuned by capacitor CN to a resonant frequency falling within the pass-band of the amplifier.
