Abstract: 1,157,398. Treating olefin copolymer elastomers. E. I. DU PONT DE NEMOURS & CO. 12 Feb., 1968 [24 Feb., 1967], No. 6846/68. Heading C3P. Sulphur curable α-mono-olefin/non-conjugated diene copolymer elastomers are reacted in bulk with a sulphur mono- or di-chloride or -bromide in an amount sufficient to reduce the cold compression set of the elastomer by at least 10% without substantially changing its sulphur curability. The polymer may be derived from ethylene, propylene and 1,4-hexadiene, dicyclopentadiene or a norbornene. Sulphur monohalides are preferred as the products are peptizable, e.g. with xylyl mercaptan. The polymer may be oil extended and the sulphur halide may be added as a solution. Reaction may be effected in an extruder. In examples ethylene/propylene/1,4.hexadiene copolymers, optionally extended with paraffinic oils, are treated with sulphur monochloride.

Patent GB-421931-A (GB)
Title: Improvements in and connected with adjustable supporting brackets for awning blinds
IPC: E04F10/06
Filed: 1934-03-05
Abstract: 421,931. Awnings or sunblinds. HESSE, C. J., 134, Nicholson Street, Footscray, Victoria, Australia. March 5, 1934, No. 6875. Convention date, March 3, 1933. [Class 52 (v)] The supporting arms 15 of awnings are slidable on vertical guides 16 at each side and are constructed so that the tension of the blind when extended imparts a turning moment to the arms to cause them to bind in or on the guides and retain the awning in adjusted position. To roll up the awning the arms 15 are turned downwardly slightly and released gradually so that the tension in the blind moves the arms upwardly on the guides. The blind 13 is mounted on a spring roller 10 and has its free end connected to a cross-bar 14 rigidly secured to the arms 15 which are forked at their inner ends to embrace the guide rail 16 and provided with rollers 17 adapted to bind upon the front and rear faces of the rail under the tension of the blind. To release the arms 15 a cord 22 passing to the interior of the building is pulled to overcome the tension of the blind whereupon the arm 15 moves upwards into the position shown in dotted lines and the blind is rolled up. For lowering the blind an operating cord 21 is attached to one of the arms 15 and passes over a pulley 20 at the end of an arm 18 pivoted to a bracket 19 fixed to the window &c., the cord passing through a hole in the bracket 19 to the interior of the building. On pulling the cord 21 the arm 18 is first moved to the horizontal position in which its end abuts against the bracket 19, and the arms 15 are thereupon lowered. When the tension on the cord 21 is relieved the arms 15 are automatically gripped on the uprights 16 and the arm 18 drops to the vertical position. The arms 15 may be telescopic. The guide rails 16 may be curved to allow the arms 15 to take up various angular positions. Instead of having rollers 17, the arms 15 may be provided with forked slotted inner ends adapted to engage the front and rear of the rail, or the inner ends of the arms may be formed into spirals embracing the rail. Fig. 13 shows a modification in which a block 39 fixed to the arm 15 slides in a channel 38 having a horizontal portion at the top ; the tension of the blind tilts the block so as to bind it in the channel. Fig. 12 shows a further modification in which the arm 15 has a rectangular pin 34 rotatable in the round part of a keyhole slot 32 in a bracket 29 slidable on the upright 16 ; on turning the arms 15 into a horizontal position the pins 34 engage the slots 33 to retain the blind in the operative position. The bracket 29 is retained in its raised inoperative position by engaging a slot 36 in the upright 16 under the influence of a spring 37. The roller 10 may be carried by the arms 18 and the free end of the blind fixed to the window &c.
Patent GB-563698-A (GB)
Title: Improvements in circuit arrangements employing thermionic valves
IPC: H04L27/06
Filed: 1943-04-30
Abstract: 563,698. Valve relaying circuits. BRITISH THOMSON-HOUSTON CO., Ltd., and DYSON, J. April 30, 1943, No. 6890. [Class 40 (v)] An operation is effected at a predetermined amplitude of oscillation by deriving a D.C. potential proportional to the amplitude and applying it to the grid of a valve, the anode circuit of which contains the control winding of a saturable reactor. The reactor is also provided with an operating winding and an auxiliary winding, the current through which is adjustable to neutralize the ampere turns of the control winding. The Figure shows an aerial 2 and crystal 1 coupled to a D.C. amplifier, output from which is applied to a valve having a control winding 5 in its anode circuit and so connected to the D.C. amplifier that an increased voltage decreases the anode current. In a modification, the output of the D.C. amplifier is applied between the grid and high tension positive of the valve, the cathode of which is returned to a potentiometer across the high tension source so that degeneration is obtained. The invention is applicable to the plotting of polar radiation diagrams in which case a number of valves are associated with a receiver and D.C. amplifier adapted to operate at different voltage levels. The transmitter is arranged to be orientated about a single axis or about two axes at right angles so as to scan a field which includes the receiving aerial. A source of light and a photo-sensitive surface are used to plot on rectangular co-ordinates the position at any instance of the orientation of the transmitter. Relays control a light source so that a spot is produced whenever the field strength crosses the contour line. Contour lines are subsequently drawn in by hand.

Abutting edges of the panels of layers 105, 107a are sealed by non-setting mastic whereon abutting edges of the panels of layers 106, 106a are sealed by flexible foam 113, Fig. 5, and by flexible tape. The barrier 6 comprises a doublewalled steel frame 211, Fig. 10, bolted to a concrete frame 207 set in the walls, floor and roof of the adit, and an access opening 219 in frame 211 is closed by a removable cover 223. In operation air is displaced from the cavern by inert gas delivered from a source 25 through initial cool-down spray lines 26 and the liquid fill line 30, whilst return purge gas is exhausted through a liquid withdrawal line 38 and a vapour return line 32. Initial liquid injection is through lines 26 and nozzles 28 and displaced gas returning through line 32 is flared at 48 until said return gas comprises pure methane after which the return gas is either re-liquefied at 50 or delivered to a consumer line 49. When cooldown is completed liquid methane is fed to the cavern through fill line 30 and may be withdrawn by a pump 56 discharging through a line 38 into a vaporizer 35.

IPC: G21C3/08
Filed: 1963-02-21
Abstract: 1,057,394. Fuel elements. C. A. PARSONS & CO. Ltd. Nov. 29, 1963 [Feb. 21, 1963]. No. 7095/63. Heading G6C. In order to reduce temperature gradients in a fuel element housed in a reactor moderator channel through which coolant is circulated, the coolant is directed into contact with the fuel element so as to flow over the element in a direction transverse to the longitudinal axis of the element, the cross-section of the fuel decreasing in the direction of said flow. Fig. 3 shows a fuel element having a herring bone fin pattern. The general coolant flow direction is along the moderator channel 3, but coolant confined in the inter-fin channels flows along them towards the outer side edges of the element, thus inducing a vortex flow. Guide plates 5 extend along the channel and may be attached either to the channel bore, or to the fuel element. In a modification, Fig. 4, the fins are perpendicular to the longitudinal axis of the fuel element, and coolant is diverted to flow between them by deflectors 5a (also Fig. 6, not shown). A second modification (Fig. 9, not shown), is similar to Fig. 1, except that the sides of the element each have two inclinations. A third modification shows a fuel element of elliptical section. Instead of fins, grooves in the can, or guide members alone may be used to induce transverse flow.
