Abstract: 631,360. Valve circuits. SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 22, 1947, No. 13797. [Class 40 (vi)] A timing circuit comprises at least two timing valves of the type having a " Miller " feed-back capacitor between anode and control grid so that when anode current is initiated the anode potential falls until, after a predetermined delay, the current in the screen grid circuit rises. The circuit comprises a switching valve which has its control grid capacitorcoupled with the screen grid of the first timing valve and its anode capacitor-coupled to the suppressor grid of the second timing valve so that when at the end of a timing period the screen grid potential of the first timing valve falls a positive-going voltage is applied to the suppressor grid of the second timing valve and a timing period of the second valve is initiated. The Figure shows a circuit comprising timing valves V1, V4 and switching valves V2, V3. When a timing period commences the anode current of valve V1 flows and the anode potential progressively falls until after a given delay the current to the screen rises, the negative going potential change being applied to the control grid of switching valve V2. The rise in anode potential of valve V2 is applied. to the suppressor grid of valve V4 thus inititating a timing period by this valve, which when it terminates passes a negative going voltage to the control grid of valve V3 and thus a positive going voltage will be passed from the anode of V3 to the suppressor grid of V1 and the cycle recommences. Specification 602,642 is referred to.

Title: Process for polymerising and copolymerising ª‡-olefines and diolefines
IPC: C08F297/06
Filed: 1961-04-17
Abstract: Polymers of alpha-olefines and diolefines are made by polymerizing one or more of the monomers in the presence of a polymerization catalyst which is "soluble" in the reaction medium and which has been obtained by the polymerization of an unbranched alpha-olefine containing at least six carbon atoms in the presence of an organo-aluminium compound, and a compound formed by the reaction of a tetravalent titanium compound with an organo-aluminium compound. By "soluble" is meant that the catalyst does not form a precipitate in the polymerization reaction medium.  The compound formed by reducing the Ti-compound e.g. TiCl4 or TiBr4, with conventional aluminium compounds, may be heat-treated for 1 to 5 hours at 60 to 120 DEG C., after washing with inert organic media and this compound after activation with the usual organo-aluminium compound used to polymerize hexene-1, heptene-1, octene-1, nonene-1, dodecene-1, or tetradecene-1, thereby forming the desired "soluble" catalyst.  This polymerization may be effected in bulk or in the presence of a hydrocarbon solvent.  The monomers polymerized with the soluble catalyst, may be ethylene, propylene, butene-1, 4-methyl-pentene-1, butadiene, isoprene, 1:5 hexadiene, and mixtures thereof.  The copolymerization of ethylene and propylene, ethylene and butene-1, and ethylene, propylene, and isoprene are exemplified. Specifications 471,590, 794,739, 810,023 and 810,024 are referred to.

Title: Improvements in Metal Drawing Apparatus.
IPC: B21C3/12
Filed: 1918-08-27
Abstract: 119,227. Ball Rolled Tube Corporation, (Assignees of Brinkman, L. H.). Aug. 29, 1917, [Convention date]. Rolling; mandrels.-Machines for reducing or shaping rods or tubes, by passing them through a die having balls operating on the metal, are constructed so as to prevent uneven wearing of the balls which are given a rotating movement having a component parallel to the length of the rod, &c., thereby assisting the rolling or drawing action, and in some cases dispensing with the necessity of a draw head. The mandrel and the die may be cooled by a circulating liquid. For drawing a tube 7, the tube is drawn by an electrically-driven chain 18, having toggle grippers 13 which grip a plug secured to the tube. The tube is shaped between the head 28 of mandrel 6, fitted with a cooling tube 60 for circulating water, and between a die formed of balls 29 which are confined between a fixed ring 56, secured to a cup 32 which screws into a member 42 secured to the machine frame and held thereto by a screwed ring 43, and rotating rings 30, 48 which are respectively splined to independently rotating sleeves 31, 44 driven by herring bone gearing at different speeds in the same or opposite directions. The ring 48 is formed with radial ribs forming cavities for the balls, and with inturned parts 50 which prevent the balls from dropping when the tubes are withdrawn. The ring 30 tends to rotate the balls about an axis parallel to the axis of the tube 7, and the ring 48 about an axis perpendicular to this, so that the resultant motion is about an inclined axis and has a component parallel to the length of the tube 7. Various adjustments of the parts may be effected to enable tubes of different sizes to be formed; thus the ring 30 is adjustably held relatively to the sleeve 31 by varying the positions of washers 37, and the sleeve 31 itself is similarly adjustable. The die is cooled by means of a fluid admitted by a pipe 52, leaving by a pipe 59, and passing through passages 51, 53, 54, 57.
