Patent GB-717792-A (GB)
Title: Improvements relating to the manufacture of chlorinated benzenes
IPC: C07C17/25
Filed: 1952-07-07
Abstract: Chlorobenzenes having three or more chlorine atoms in the molecule are produced by a process of thermal decomposition of a polychlorocyclohexane having six or more chlorine atoms in the molecule, in which the chlorobenzenes produced are volatilized continuously or intermittently from the resulting mixture, the polychloro cyclohexane is separated from the chlorobenzene by fractional condensation and the polychloro cyclohexane is refluxed to the reaction mixture.  Preferably the polychlorocyclohexane, which may suitably be a mixture of isomers of hexachlorocyclohexane produced by the chlorination of benzene in the presence of light, is decomposed by heating to a temperature not exceeding 350 DEG  C., at atmospheric or superatmospheric pressure and the chlorobenzenes are removed by fractional distillation using a fractionating column.  In examples (1) and (2) alpha hexachlorocyclohexane is thermally decomposed to trichlorobenzene and (3) a mixture of isomers of hexachlorohexane is thermally decomposed to trichlorobenzene.

Title: Apparatus for registration of beta radiation of low intensity, with correction for cosmic radiation
Inventor: THEODORSSON PALL
IPC: H01J47/06
Filed: 1959-05-20
Abstract: 874,721. Radiation measuring apparatus. ATOMENERGIKOMMISSIONEN. May 20, 1959 [May 20, 1958], No. 17075/59. Class 40(3) [Also in Group XL(a) ] The invention relates to apparatus for the measurement of low intensity beta radiation in the presence of cosmic radiation, more particularly mesons, utilizing at least one ionization chamber arranged to be responsive to beta radiation and at least one compensation ionization chamber arranged to be responsive only to the cosmic radiation, the two chambers supplying their signals to a recorder via an anti-coincidence circuit whereby impulses due to cosmic radiation in the first chamber are cancelled by corresponding impulses from the second chamber and only impulses due to beta radiation are recorded. According to the invention, and as illustrated in a first embodiment, Figs. 3 and 4, the two chambers 17 and 18 are of shallow form with flat and parallel end walls 25, 26, 27 and each incorporates a single system of anodes consisting of at least two wires 9 and a cathode system consisting of chamber side walls 22, 24 and at least one cathode wire 12 disposed parallel to the anode wires, the two chambers being disposed with end walls closely adjacent or, as illustrated, constructed with a common end wall 25. Chamber 17 comprises the measuring chamber and has a plastic window in one end wall 27 to admit the beta radiation, whilst chamber 18, which comprises the compensation chamber, has walls made wholly of metal, e.g. brass or copper. Connection tubes (not illustrated) are provided to permit the circulation of an ionization gas, e.g. a mixture of propane and argon, through the chambers. A second compensation chamber 19 incorporating a single anode wire 20 entirely surrounds chamber 17 and is effective in the case of mesons arriving horizontally. In a second embodiment, Figs. 1 and 2 (not shown), chamber 19 is omitted. In a third embodiment, Fig. 5 (not shown), the compensation chamber is appreciably larger so as to project beyond the side walls of the measuring chamber, and in a fourth embodiment, Fig. 6 (not shown), a second compensation chamber is disposed below the measuring chamber and spaced away from it by a distance sufficient to permit the introduction of an assaying cup with a substance whose radiation is to be measured in front of the plastic window. A fifth embodiment, Fig. 7 (not shown), has two measuring chambers, one exposed directly to an assaying cup for alpha particles and the other above it for beta particles. The alpha chamber will respond to both alpha and beta particles but is operated in the proportional region so that the particles may be distinguished in terms of resulting pulse amplitude. As an alternative a single proportional chamber may be used for both alpha and beta measurements. A sixth embodiment, Figs. 8 and 9 (not shown), is similar to the second embodiment referred to above but employs chambers of circular cross-section.

Abstract: 430,691. Table-game boards. McCLELLAN, F. C., 4223, West Lake Street, Chicago, U.S.A. June 8,1934, No. 17086. [Class 132 (ii)] A table game board has a plurality of openings of high scoring value into which balls may be advanced from the openings in which they were initially received when a ball is played into a particular opening in the board. A ball 50 passing through the opening 27 in the inclined board 12, Fig. 2, passes through an opening 31 in a sliding panel 17 to drop on to the lever 33 which is thus rotated to make the contacts 36, 37 of the mercury switch 34 which energizes the solenoids 42. Each solenoid 42, Fig. 3, has an armature 43 with extension 44 disposed beneath an opening 25 in the board 12 so that on energization of the solenoid the extension 44 moves upwards to dislodge a ball 15a which has been played into the opening 25 which then rolls into an opening 26, Fig. 1, of higher scoring value through the loop 48 and the pins 28. Ordinary openings 23 and a "no count " opening 30 are provided. The sliding panel 17 has the usual openings 18 therein through which the balls fall on to the floor 20 down which they roll to a space from which they may be lifted one at a time, by a ball elevating device having a handle 22, into the lower end of the channel 16.

Abstract: 549,041. Shock absorbers, gyroscope mountings. SPERRY GYROSCOPE CO., Inc. Dec. 2, 1940, No. 17178. Convention date, Dec. 2, 1939. [Class 108 (iii)] [Also in Group XX] A liquid damper comprises a bath or cylinder 21 and a piston like member formed by a number of spaced plates 26 secured to a rod 24<SP>1</SP> and a number of interleaved annular discs 30 loosely mounted, the arrangement being such that longitudinal movement of the piston is resisted by throttling between the edges of the loose discs and the cylinder while lateral movement is checked by the viscosity of the liquid between the plates and the discs. Several such damping devices may be arranged between the inner ring 4 of a gimbal support and the plate 16 supporting a compass as described in Specification 506,582. The lower end of rod 24<SP>1</SP> secured-to the ring of the compass support 4 depends into the cylinder 21 carried by ring 16. Plates 26 are spaced apart by washers 28 and each space thus formed accommodates an annular disc 30 which is larger than the washer and slightly smaller than the cylinder 21 and thus has limited freedom of movement relatively to the rod 241.

Abstract: 1,249,596. Tubular heat exchanger elements. A. BANNER, and F. BANNER. 13 April, 1970, No. 17377/70. Heading F4S. [Also in Division F2] A protective insert sleeve 1 of hygroscopic plastics material, for a condenser tube 3, has a flange 2 at one end and for one portion 5 of its length, has a transverse dimension greater than that for the rest of the sleeve. This transverse enlargement 5 is achieved by distorting the sleeve into an oval or rectangular cross-section from a circular cross-section. The wall thickness of the sleeve 1 decreases from its flanged end to its other end. The sleeve 1 is of hygroscopic nylon so that when it is inserted in the condenser tube 3, it expands due to absorption of water in the condenser tube, and grips the condenser tube.

Class 79(5) [Also in Group XXXIV] A combined accelerator and brake pedal 42, Fig. 1, is pivotally mounted for swing- ing movement about horizontal and vertical axes 16, 38 on a bracket 11 above the vehicle floor board 21. The pedal 42 is swung laterally about a vertical pivot 38 on a lever 18 for operating the accelerator while the lever 18 is itself mounted on a horizontal pivot 16 and actuates the brake cylinder 26 through a depending arm 20 when the pedal 42 is swung forwards. Light pressure on the pedal 42 is prevented from operating the brakes by a spring- loaded catch comprising a roller 88 on an arm 90 engaging a recess 86 in an extension 84 of the lever 18 and yieldingly returned by a spring 94. Springs 30, 48 normally return the pedal 42 to the initial position. Lateral movement of the pedal 42 actuates the throttle through a push rod 70, Fig. 7, which is coupled to an arm 50 swinging about a vertical pivot 52 and having a recess 59 in which an extending arm 58 of the pedal 42 normally engages when the brakes are not applied. When the brakes are applied the arm 58 moves out of the recess 59 and releases the arm 50 so that the throttle automatically returns to its idling position. Movement of the arm 50 is limited by adjustable stops 60, 62.
