Title: Torpedo homing system and method
IPC: F42B19/10
Filed: 1955-08-31
Abstract: 905,330 Steering torpedoes. CLEVITE CORPORATION. Aug. 31, 1955. [Sept. 7, 1954], No. 25073/55. Class 9(2). In a torpedo homing system acoustic signals from a target control the torpedo to circle in either direction alternately, reversing when reception ceases, so that the target is approached along a sinuous path which becomes progressively straighter as the torpedo swings through shorter ares. Electric signals from a transducer 30 feed a receiver circuit 31 having automatic gain control 32. When a signal is received, a relay 1 (a) actuates a speed control 34 to reduce the rate of turn of the torpedo as controlled by a gyro-azimuth motor 33, and (b) reduces gradually the gain in the amplifier of the receiver to diminish the sensitivity of the listening apparatus, so that it loses the target without going far beyond the true approach line. When the received signal is no longer strong enough, relay 1 operates again and (a) actuates a relay 2 to reverse the direction of the motor 33, (b) increases the speed of the motor 33, and (c) increases amplifier gain to increase sensitivity so that the torpedo is brought " on target " again with little loss of time. While the torpedo is " on target " the depth control is functioning, as in the prior art, and this control functions more effectively, as the torpedo is " on target " for a relatively larger proportion of the time.

Title: Improvements in or relating to olefine polymerisation catalysts and to olefine polymerisation processes involving the same
Inventor: LUFT NORBERT WALDEMAR
IPC: C08F10/00
Filed: 1955-09-01
Abstract: In the preparation of Ziegler-type catalysts the complex formed by reducing the Group IV to VI compound with an organo-metallic compound or a derivative thereof is separated and mixed with a further amount of the second compound.  For example, titanium tetrachloride is mixed with aluminium diethyl chloride, and the resulting brown precipitate is suspended in iso-octane and a further quantity of aluminium diethyl chloride added, which may be the supernatant liquor from the first reaction still containing the aluminium compound, to form the final catalyst.  It is stated that the yield of polymer is a function of the amount of the first precipitated compound used, while the amount of the metallo-organic compound controls molecular weight of the product. Polymerisation may first proceed with the original precipitate as catalyst, and the organo-metallic compound which may be the same or different from that used in the first stage, added at a later stage or stages to reactivate the catalyst.  The process is applied to olefines especially mono-olefines to give solid polymers and co-polymers using the catalyst components described in Specifications 799,392, 799,823, 801,031, 829,627 and 829,628.ALSO:In the preparation of catalysts of the Ziegler type for low-pressure polymerization of olefines, the complex formed by reducing the Group IV to Group VI compound with an organo-metallic compound or a derivative thereof is separated and mixed with a further amount of the organo-metallic compound.
