Abstract: 1,140,854. Automatic attitude control. M. BEZU. July 12, 1966 [July 28, 1965], No. 31251 /66. Heading G3R. [Also in Division H2] In an electrically operated follow-up system, e.g. for a stabilized platform, the stator 1, 4 of the main driving motor coupled to the load 6, is also driven round by an auxiliary motor 2, so that the main motor always operates at low slip and therefore at its greatest torque potential. Positional errors of the stator 4 and rotor 5, 6 are simultaneously detected and corrected by simultaneous action of both motors. As shown, the error of stator 1 with respect to mounting frame 7, and the error of member 6 with respect to motor stator 4 are detected at 13, 15 respectively. But in a modification Fig. 3 (not shown) the error of a reference element 12, e.g. a gyroscope, is detected with respect to the main motor stator, while the auxiliary motor is energized in dependence on the error between the member 6 to be stabilized and the same motor stator. The bearings are loaded and the resultant friction is overcome by the auxiliary motor.

Abstract: 1,245,969. Release unit. AVIATION, MINISTER OF. 30 June, 1969 [1 July, 1968], No. 31276/68. Heading B7W. [Also in Division E2] A release. unit for, for example, releasing satellites from the final stage of their launch vehicles, comprises a body member 10, a secondary member 12 and a locking member 13 intermediate the body member and the secondary member, the body member 10 and secondary member 12 being movable relative to each other from a hold position in Fig. 1, in which they engage and hold the locking member 13 in a hold position in which it can engage and hold a releasable member 14, to a release position in Fig. 2 (not shown), the movement from the hold to the release position being effective as a result of a co-operation between inclined surfaces on the body member and/or the secondary member on the one hand and on the locking member on the other hand to which surfaces are inclined to the direction of relative movement to move the locking member 13 to the release position in which it can no longer engage the releasable member. The release unit is operated from the hold position in Fig. 1 by a fluid pressure power means 32, which may be a pyrotechnic gas generator, which forces the piston 12 to the left, severing the safety screws 29, misaligning the flanges 25 on the locking member 13 from the flanges 27 on the skirt 26 of the piston 12 and thereafter the conical surface 18 on the body member 10 co-operating with the conical surface 20 on the piston 12 forcing the locking member 13 radially outwards against the bias of an annular retaining spring 22 and thus disengaging the locking member 13 from the V-form groove 28 and releasing the releasable member 14. A piston groove 31 may be incorporated so that it shears when the end of the skirt 26 furthermost from the piston strikes the end wall 15 and the broken edge scores into the body member 10, preventing the return of the piston and thus preventing accidental relocking of the releasable member 14 by the locking means 13.

Title: Method of and apparatus for measuring the degree of circular polarisation produced by a transparent body
IPC: H05H1/00
Filed: 1968-07-03
Abstract: 1,219,667. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. 3 July, 1968 [4 July, 1967], No. 31830/68. Heading H1C. The electron density of a plasma is measured by locating a plasma cell 3, Fig. 1, within a laser resonator 2<SP>1</SP>, 2<SP>11</SP> containing a gaseous active medium, and subjecting the plasma to a magnetic field 4 directed along the optical axis 5 so as to cause the laser to oscillate simultaneously in two adjacent modes, the frequency difference between the modes-which is determined by the electron density-being detected by a photo-sensitive element 6. The gaseous active medium, e.g. helium-neon, has plane windows normal to the optical axis and emits unpolarized light of wavelength 3À39 Á. Since the magnetic field causes rotation of the plane of polarized light produced by the plasma electrons, and since the refractive index of the electrons is different for the two directions of circular polarization, emergent light of two distinct frequencies determined by the resonator dimensions and the electron density is obtained. Determination of the mode spacing detected by the photo-sensitive device 6 is effected by a counter 7. In a modification, Fig. 2, mode locking due to a small frequency difference between the modes is overcome by increasing the mode spacing. This is effected by introducing further, rotational dispersion, the laser resonator including a semi-conductor element 8 of germanium, silicon, gallium phosphide or gallium arsenide having an applied controlled magnetic field 12. In this arrangement the output mode spacing is determined by a network comprising an amplifier 9, a discriminator 10 and a recorder 11.
