Title: Improvement in the manufacture of titanium
Inventor: GRAY JAMES JOHN
IPC: C22B34/12
Filed: 1954-12-10
Abstract: In the manufacture of Ti by reaction of Ti Cl4 with metallic Na in an inert atmosphere at a temperature above the melting point of NaCl a portion of the heat generated by the reaction is withdrawn and a substantially lower temperature is maintained at the surface of the mixture near the side of the reaction vessel than at the surface near the centre of the vessel by refluxing of Na during the reaction the molten refluxed Na being returned to the reaction mixture near the side of the reaction vessel.  Refluxing of Na may be achieved by providing a lid for the reaction vessel of conical or domed or like shape, the sides of which subtend an angle to the horizontal preferably in excess of 30 degrees.  Cooling of the lid surface by contact with the atmosphere or by application of some cooling fluid such as water, oil or liquid metal causes condensation of Na on the interior surface of the lid and return of the condensed Na to the reaction mixture at the side of the reaction vessel. Specifications 720,517 and 750,355 are referred to.

Abstract: 791,054. Automatic control systems; exciting dynamos. GENERAL ELECTRIC CO. Dec. 14, 1954 [Dec. 14, 1953], No. 36196/54. Classes 35 and 38 (4). [Also in Groups XXXIX and XL (c)] Automatic control.-A dead band is introduced into a servo-control system (used in an unspecified manner for an unspecified purpose) by providing the amplifier with degenerative feedback which reduces the gain only when the input signal is small. Almost full gain is obtained for large input signals by shunting the feed-back loop with a pair of biased diodes which conduct when the signal exceeds a preset level. The amplifier may be either an amplidyne, see below; a magnetic amplifier (see Group XXXIX); or a thermionic valve amplifier (see Group XL (c)). Exciting dynamos.-An amplidyne generator 1 for the control system above has a feed-back winding 10, which opposes the main control winding 8, connected across the output terminals of the generator in series with a variable resistor 1, thus reducing the effective gain of the generator as an amplifier. The winding 10 is shunted by reversely poled rectifiers 17, 21, each in series with a biasing source 13, 19. When the output voltage exceeds the level set by the biasing sources 13, 19, the appropriate diode 17 or 21 (according to polarity) conducts and reduces the feed-back and hence provides almost full gain for large input signals, whilst the arrangement has a small gain for small input signals. Specifications 497,060, [Group XL], and 665,541, [Group XXXVIII], are referred to.

Abstract: 866,929. Injection moulding. NOTHELFER, W. Nov. 21, 1957 [Nov. 21, 1956], No. 36347/57. Class 87(2). Pressure is maintained in an injection cylinder 2 by an annular non-return valve 12 disposed at the forward end of an injection screw 6. The screw 6 is rotatable and axially reciprocable, and the valve 12 is slidable on an extension 10 of the screw. Rotation of the screw causes the injection material to move the valve 12 forwardly to allow passage of this material through bores 13 in the valve 12, Fig. 1, and an annular groove 17 and bores 9 in an injection piston 8. Forward axial movement of the screw 6 and piston 8 forces the valve 12 into contact with a conical surface 14 on the screw to prevent reverse flow of the material. In a modification, Fig. 3, (not shown), the bores 9 in the piston 8 are replaced by an open annular space surrounding the piston which is thus of smaller diameter. In Fig. 4 a short annular valve 12 having bores 13<SP>11</SP> is slidable between a surface 14 of the screw 6 and a ring 18, the piston 8 being dispensed with.
