Abstract: 750,889. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 9, 1953 [March 18, 1952], No. 6934/52. Drawings to Specification. Class 40 (3). [Also in Group XX] In a guided missile, the target is viewed by a television camera and the television picture is transmitted from the missile to a control station. At the control station, the television signals indicate the movement of the missile relative to the target and guidance signals are transmitted to the missile to maintain it on the required track. Movements of the missile in pitch and yaw tend to cause the target to move away from the camera and this is counteracted by corrective signals derived from the missile gyroscopic stabilizing system. The corrections are applied to either optical or electronic devices which stabilize the target image at the camera. In the electronic embodiment, the television pick-up tube forms an electron image before projection on to the storage electrode and control is exercised by coils, disposed round the tube, which are energized in accordance with movements of the gyroscope system and which move the electron image.

Title: Improvements in and relating to the hydroxylation of steroids
IPC: C12P1/00
Filed: 1961-03-02
Abstract: Hydroxylated steroids are produced by a microbioligol hydroxylation comprising treating a steroid reactant to produce substantially smooth-surfaced particles, wetting said particles with an aqueous medium containing a wetting agent, contacting said particles with an oxidising microbiological culture, incubating said culture containing the steroid and recovering the hydroxylated steroid.  The substantially smooth-surfaced particles may be produced by exposing raw progesterone particles to a violent turbulence created by supersonic velocity air streams, e.g. as that provided by various fluid energy type milling equipment.  The mixture of wetted steroid particles and microbial culture may be diluted with a substantial proportion of sterile distilled water, e.g. in an amount at least of equal volume to the volume of wetted steroid and microbial culture. The concentration of the steroid particles in the aqueous medium may be in the range of 20 to 50 grams of steroid per litre of medium.  A suitable steroid for use in the above process is progesterone.  The microorganism used may be Aspergillus ochracews which converts progesterone to 11a -hydroxy-progesterone.
