Title: Improvements in or relating to signal-seeking receivers
IPC: H03J7/30
Filed: 1946-09-19
Abstract: 626,221. Automatic tuning control. COLONIAL RADIO CORPORATION. Sept. 19, 1946, No. 28120. Convention date, Sept. 16, 1944. [Class 40 (v)] In a signal seeking receiver of the kind which is progressively tuned by a motor over the wave-range until a signal is encountered, a limiter followed by a narrow band filter precedes the motor control valve in order to prevent the motor being stopped by noise. One of the circuits to be tuned in a superheterodyne receiver represented by an inductance 10, and variable condenser 11 driven through clutch and brake 18, 19 by a motor 12. An output from an intermediate frequency stage of the receiver is applied at 1, 2 to a limiter valve 31 and the limited signal is passed through a crystal gate to the grid of thyratron 14. When a signal of sufficient strength is received the thyratron fires and operates relay 15. This breaks the motor circuit and releases magnet 22, disengaging the clutch and applying the brake. The forward contact 15f connects a reactance comprising an inductor 17 and capacitor 16 across the tuned circuit to compensate for the motor over-run. A cam-operated contact 20 ensures that the motor only stops when the condenser is in the 180 degrees of its movement when the capacitance is decreasing and the sense of the compensation therefore correct. The motor is restarted by button 14s which discormects the cathode circuit of the thyratron. If the receiver is of the tuned radio frequency type, the crystal gate is replaced by a variably tuned circuit ganged with the main tuning control. The circuit 10, 11 may alternatively be tuned by an inductance having an adjustable core operated by a cam.

Title: Reduction of titanium oxides
IPC: C22B34/12
Filed: 1956-09-19
Abstract: In a process for reducing Ti oxides, a mixture comprising Al and an alkaline earth metal hydride is heated until it volatilizes and the gases thereby obtained are directly reacted with Ti oxide.  In carrying out the process the Ti oxide is kept separate from the other components, for example in an upper unheated zone separated by perforated plates or screen from a lower zone in which are placed the Al with the hydride of Ca, Ba, or Sr, heated to 900 DEG -1000 DEG C. after evacuation of the whole.  In an example 1600 gm. of a crude hydride containing 68 per cent CaH2 are mixed with 30 gm. of readily pulverizable alloy of equal part by weight Ca and Ai and placed in the lower zone of a Cr-Ni steel reaction vessel, 1000 gm. of TiO2 being in the upper zone.  The apparatus is evacuated to 10-3 mm. Hg. and the lower zone heated to 1000 DEG C.  Hydrogen evolved having reduced the TiO2 to a lower oxide and heated it to about 800 DEG C., is extracted and the pressure again reduced to 0.1 mm. Hg. Ca now vaporizes and completes the reduction.  The contents then cool in hydrogen at 1 atmosphere and are washed to remove CaO &c. and leave a hydrogenated Ti containing 0.2 per cent oxygen and 0.015 per cent nitrogen which can be worked up by known methods into compact ductile Ti.  Specification 803,767 is referred to.

The tube 8 is borne by the carriage 2 of a handling machine 1 movable above the reactor core on rollers 4 along a horizontal beam 3 of a rotary gantry, and is rotatable on bearings 6, 7 by a motor 11 mounted on the carriage 2 via gear-wheels 9, 10. A prismatic element 13 being loaded into the reactor core is suspended inside the tube 8 by a grab 14 engaging with a head 15 on the upper end of the element, the grab 14 being controlled by means of a winch (not shown) on which a cable 16 connected to the grab is wound. The inner end of each flap 17 comprises a roller 20 while its opposite end has a fork 21 by means of which it is articulated to the rod 23 of a pneumatic or electromagnetic jack whose frame 24 is articulated to an upper collar 26 of the tube 8. In order to correctly orientate the element 13 in the tube 8, the flaps 17 are tilted synchronously and their rollers 20 contact alternate faces of the element which is thus rotated until the rollers are parallel with the faces they contact. In order that the apparatus will operate correctly in the case where edges of the element 13 are adjacent the centre of each flap 17, an ancillary apparatus allows a preliminary feeling of the element 13 and enables it to be given a relative rotation. adequate to prevent the flaps 17 from acting on the edges of the element. The feeling apparatus comprises three feeling members 27-29, the displacements of which depend upon the position of the element 13 and which are determined by electromagnetic pick-ups connected to an electric circuit 30. Once the element 13 has been correctly orientated in the tube 8, the tube is rotated by just the right amount for the element to register accurately with the recess in the core after the rotation of the rotary gantry beam.
