Title: Compounds of the cyclopentanopolyhydrophenanthrene series and methods for producing them
IPC: C07J31/00
Filed: 1952-02-18
Abstract: The invention comprises a D 5-7-thiocyan- or isothiocyan-steroid compound and the preparation thereof by treating a compound of the cyclopentanopolyhydrophenanthrene series having a D 5-double bond with dithiocyanogen whilst irradiating the reaction mixture with ultra-violet radiation. Subsequently the 7-thiocyan or isothiocyan compound may be converted to a 7-dehydro compound by heating in an organic solvent, e.g. a tertiary amine, preferably in the presence of an acid-binding inorganic substance, such as an oxide or a hydroxide of an alkaline earth metal.  The reaction may suitably be effected in dimethyl-or diethyl-aniline or quinoline at temperatures above 100 DEG  C.  A 7-hydroxy compound is obtained by heating a solution of the 7-thiocyan or 7-isothiocyan compound in an aliphatic alcohol, e.g. butanol, with an aqueous solution of a weakly alkaline substance, e.g. an alkali metal carbonate.  Examples describe the preparation of 7(a )-thiocyancholesterol, 7(b )-thiocyancholesterol and the benzoate thereof, 7(b )-isothiocyancholesterol and the benzoate thereof, the acetates of 7(a )-thiocyan-pregnenolone and 7-thiocyan-dehydro-isoandrosterone, 7-dehydro-cholesteryl benzoate and pregnenolne benzoate, 7(b )-hydroxy-cholesterol and D 5-pregnenol-3-on-20.

Title: Improvements in or relating to fluid pressure gauges
IPC: G01L9/00
Filed: 1954-02-15
Abstract: 773,677. Fluid-pressure gauges. GENERAL ELECTRIC CO., Ltd., MASON, M. T., and MATTHEWS, A. Feb. 14, 1955 [Feb. 15, 1954], No. 4394/54. Class 40 (1). [Also in Group XIX] A fluid pressure gauge comprises: (i) two pressure chambers separated by a flexible diaphragm, (ii) a movable magnetic member in one of the chambers and mechanically coupled to the diaphragm, (iii) one or more inductance coils disposed outside the pressure chambers. In use of the gauge movement of the magnetic member due to displacement of the diaphragm by the pressure to be measured causes a variation of the self or mutual inductance of the coil or coils. This change in inductance is measured by a suitable instrument. In the embodiment shown in Fig. 1, two inductance coils 5, 6 surround two fixed magnetic cores 26, 27, air-gaps 28, 29 and a central axially movable magnetic core 7 enclosed in a non-magnetic tube 19. The latter is secured to a short tube 14 which supports a flexible capsule 13 (e.g. of beryllium-alloy) in a pressure chamber 4. The tube 19 is sealed at its upper end by a plug 21 so that the second pressure chamber 24 comprises the interior of capsule 13. The movable core 7 is secured to a rod 30 into which is screwed a rod 32 extending from the lower wall of capsule 13. The fluid whose pressure is to be measured is fed into pressure chamber 4 via inlet conduit 25 and movement of the wall of capsule 13 in accordance with the differential pressure between the two chambers 4, 24 moves magnetic core 7 so as to vary the widths of the air-gaps 28, 29 and thus vary the self-inductance of the two coils 5, 6 differentially. The coils 5, 6 may be connected in the circuit disclosed in Specification 759,041 in order to give an indication of the pressure to be measured. The apparatus shown in Fig. 1 comprises a zero adjuster described and claimed in Specification 773,678. The zero adjuster comprises a bolt 34 threaded into the end of rod 32 and passing through a U-shaped cross-section member 33. By rotating the bolt 34 the wall of capsule 13 enclosed by member 33 is distorted and this moves magnetic member 7 to adjust the air gaps 28, 29. In a modification, Fig. 2, not shown, the fluid whose pressure is to be measured feeds into the capsule interior. One of the pressure chambers may be evacuated.

Abstract: 986,318. Inertial navigation systems. FERRANTI Ltd. Feb. 4, 1964 [Feb. 6, 1963], No. 4800/63. Heading G1C. An inertial platform of the kind having X and Y-axis gyros 4, 5 for stabilizing the platform about the X and Y-axis in accordance with signals derived from Y and X-axis accelerometers 7, 8 respectively, and a Z-axis gyro 6 for stabilizing the platform about the Z-axis, includes means for aligning the X-axis of the platform with the East-West direction, comprising an integrator for integrating the output signal from the Y-axis accelerometer 7 in the X-axis gyro loop, means for dividing the said output by a signal representing the product of the earth's rotation rate and the cosine of the lattitude at which the platform is located to determine the deviation of the X-axis from the East-West direction and means for applying a precession signal to the Z-axis gyro 6 for a time proportional to this deviation, the signal being such as to cause the Z- axis gyro to rotate the platform to remove the deviation. Prior to use the platform is approximately aligned with the X-axis disposed East- West by reference to e.g. a gyro-magnetic compass and the following procedure is then adopted using the circuit of Fig. 2. Switches 12, 16, 18 are opened and the switch 20 closed, and the switch 29 is moved to the position 2a for a set time e.g. ten minutes, the switch 37 remaining open. The signal from the Y-axis accelerometer is applied to the integrator formed by an amplifier 32, motor 33 and tachometer generator 34 and causes rotation of the shaft of the motor 33 from a zero position. The switch 29 is then moved to position 3 and the switch 37 closed. For all positions of the switch 35 other than the zero position one or other of its segments makes contact with the infer according as to whether the deviation of the X axis from East-West is positive or negative. Thus a constant current source 36 is connected to the precession coil of the 2-axis gyro 6, and the output signal from the Y- axis gyro (proportional to the cosine of the latitude) is applied to run the output shaft of the motor 33 back to zero. In this way the X-axis is aligned with the East-West direction, the theory being discussed in the Specification. The use of the apparatus in normal operation with the switches 12, 16, 18 closed switches 20 and 37 open and with the switch 29 in position 1 is also described in the Specification, the Z-axis gyro being then precessed only by a signal from a source 39 which signal represents the product of the earth's rotation rate and the sine of the latitude.
