Duct 7 is connected to chamber 20 of valve 8, the spool 11 providing an adjustable throttling orifice 34 via grooves 13 and chamber 14. Chamber 20 is also permanently connected via a small opening 19 and passage 18 with a chamber 21 which is connected to chamber 28 in valve 9, the spool 23 controlling a throttled outlet 35 from chamber 28. Changes in pressure P 2  cause movement of spool 23 to vary the pressure P 3  in chambers 28 and 21, which causes movement of spool 11 to vary the throttle opening 34 and thus adjust the pressure P 2 , the ratio of the surfaces 2α and 2b of piston 2 acted on by pressures P 2 , P 1  being the same as the ratio of the areas of surfaces 25α, 24α of spool 23 acted on by the same pressures.

Title: Solid state scanning system
Inventor: SANDBANK CARL PETER
IPC: H03K4/48
Filed: 1965-10-27
Abstract: 1,136,254. Electroluminescence. STANDARD TELEPHONES & CABLES Ltd. 21 Oct., 1966 [27 Oct., 1965], No. 45460/65. Heading C4S. [Also in Division HI] A solid state scanning system comprises two semi-conductor bodies in which high field domains can be propagated in mutually orthogonal directions. In a typical arrangement, Fig. 5, strips 15, 16 of cadmium sulphide and N-type gallium arsenide or indium phosphide respectively with end terminals 17, 18, extend in mutually orthogonal directions on glass substrate 13. The substrate also carries mutually orthogonal sets of conductors 11, 14 on opposite faces of an electroluminescent panel 19 which are capacitively coupled to the respective strips via silica films. When voltages in excess of the threshold are applied between terminals 17, 18, high field domains are propagated along the strips by electron-phonon interaction and Gunn effect respectively. The domains give rise to voltage pulses as they pass under respective sets of conductors. The electroluminescent panel is thus energized at the intersection of conductors on which coincident pulses are received to provide scanning, the light intensity being controlled by a modulating signal applied between the two sets of conductors. Since the Gunn effect domains propagate much faster than those produced by electron-phonon interaction the system provides a fast x and slow y scan. An alternative structure comprises an electroluminescent panel sandwiched between and capacitively coupled through insulation to mutually perpendicular strips of the respective semi-conductors (Fig. 6, not shown). This system dispenses with the sets of conductors. Arrangements for producing coded outputs from a single semi-conductor strip are also described.

Title: Improvements in or relating to refractory uranium compounds
Inventor: ACCARY ANDRE
IPC: C01B21/06
Filed: 1961-12-19
Abstract: Powdered refractory uranium compounds are prepared by forming, e.g. by sintering, a compacted body of the uranium compound and a metal or alloy which metal may be the same as that in the refractory compound, and treating the compact body with at least one agent to cause disintegration of the body, e.g. by chemical reaction with or dissolution of the metal, and separating the compound in powder form, e.g. by mechanical or physical means. The compacted body of proportions in the range 60-95% refractory compound and 40-85% by weight metal or alloy, may be subjected to a grain refining heat treatment at 1000-1200 DEG  C. and pressure 10-4 to 10-6 mm. Hg for 1-8 hrs.  In specific Examples: (1) a compact body of uranium carbide and uranium metal having 3-4.4% C is disintegrated by H2 at 200-300 DEG  C. forming uranium hydride and uranium carbide powder which is separated by classification in a liquid or by centrifuging, alternatively the hydride may be decomposed by heating at 400 DEG  C. in vacuo and the mixture of uranium carbide and uranium metal separated; (2) a compact of uranium nitride and uranium is treated with N hydrochloric acid at 60 DEG  C. to give uranium chloride in solution and the uranium nitride powder is filtered off, washed with water, alcohol and acetone and dried in vacuo; (3) a body of uranium silicide U3Si2 and its eutectic with uranium metal is treated with H2 or hydrochloric acid to give particles of uranium silicide which are separated physically from other reaction products.

An electromagnet according to the Main Patent is improved by arranging the widths of the armature laminations so that longitudinal grooves are formed to allow liquid to pass between the ends of the armature. This reduces the damping effect of the liquid. As shown, Fig. 2, the armature comprises a stack of laminations 1 having outer members 2 which are narrower than is required to fill the housing tube 6 so that grooves 5 are formed. The faces 2<SP>1</SP> of the outer laminµ are flat, thus providing further channels 8. The widths of all the laminae may be selected so that longitudinal grooves are provided along the whole circumference of the armature. The laminations are held together by rivets (3, Fig. 1, not shown) which are insulated by an oxide layer, a coat of lacquer or an insulating tube. The laminations may alternatively or in addition be secured by adhesives or casting resins which also prevent eddy currents.
