Abstract: 563,321. Borehole clinometers; gyroscopic apparatus. SCOPHONY, Ltd., and WIKKENHAUSER, G. April 1, 1943, No. 5225. [Classes 97 (ii) and 97 (iii)] A borehole clinometer includes a gyroscope enclosed in an evacuated chamber and brought up to substantially normal speed by a source of power which remains on the surface of the ground, the drive of the gyroscope being there after maintained by a smaller source of power. As shown, the clinometer casing 1 is divided by a diaphragm 2 into two chambers 3, 4, both capable of being her metically sealed. The chamber 4 contains an electrically - driver gyroscope 5 and may be evacuatec through a valve 16. The chamber 3 contains a battery 6 and an electric oscillator 7 feeding the gyroscope through an output transformer 8. Before the clinometer is lowered down the borehole, the large source of power is connected to terminals 12 to drive the gyroscope up to its normal speed. The power is disconnected and terminals 13 are short-circuited to connect the battery to the oscillator for maintaining the speed of the gyro. The clinometer may then be lowered down the borehole.

Title: Improvements in or relating to means for locking the joints of artificial limbs
IPC: A61F2/64
Filed: 1921-02-18
Abstract: 175,193. Sandling, G. M. Feb. 18, 1921. Limbs, artificial.-The joints of artificial limbs are locked in desired positions by the frictional engagement of a spring carried by one limb member with a cylindrical block, around which the spring is wound, fast upon the pivot pin carried by the other limb member. A knee joint, Fig. 1, normally unlocked, is locked by the weight of the wearer being put on the lower limb member and comprises two springs E carried by a bracket C attached to the lower limb member and loosely coiled round a cylinder A<1> fast on the pivot pin A which is carried by the thigh B. When weight is put on the lower limb member, a pivoted link C<1> and slotted link C<2> permit the bracket C to rise relatively to the pivot pin, causing the spring frictionally to engage the cylinder to lock the joint. The elbow-joint, Figs. 3 and 4, is normally locked through springs G<1> carried by the framework B<1> of the upper limb member engaging drums G fast on the pivot pin F carried by the lower member, being held in contact therewith by springs J. The joint is unlocked when a cord H<2> attached to a lever H<1> is pulled, the motion of the lever H<1> being transmitted to a second lever H acting in opposition to the springs J thereby releasing the springs G' from the drums. An ordinary operating-cord K for the lower limb member is provided. The device may also be used for securing artificial hands &c. to wrist sockets, as shown in Fig. 5. Springs M<2> carried by the wrist socket normally bind upon a pin L projecting from the hand-plate to retain it in desired positions. The loose ends of the springs are attached to a spring- pressed plunger N which is pressed inwards to release the joint.

Title: Improvements in or relating to colour television cameras
Inventor: TAIT DAVID RUSSELL
IPC: H04N9/07
Filed: 1956-02-24
Abstract: 856,002. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 7, 1957 [Feb. 24, 1956], No. 5748/56. Class 40(3). In an arrangement for generating simultaneous type colour television signals employing a single pick-up tube optical colour-filter means which impose a line structure on some of the colour components of the scene are positioned in the light path to the tube such that signals representative of one colour component (that on which a line structure is not imposed) appear in the tube output as video signals whilst signals representative of other colour components are derived as modulations of carrier waves having different frequencies determined by the "pitch" of the line structure which the filters impose on these components. The latter signals are then separated out by band-pass filters and the modulation components derived, as video signals, by demodulation. Fig. 3, shows a preferred embodiment for a three colour system in which light from the scene is directed on to the target electrode 11 of a pick-up tube via an optical system comprising a lenticular pair 12, 13, a lens 6 and a pair of gratings 7, 8, comprised of alternate fully transmitting strips 1, cyan (blue and green) transmitting strips 9 and yellow (red and green) transmitting strips 10. In this manner the green component of the scene is set up on the target 11 without a line structure whilst the blue and red components have line structures of different "pitches" determined by the spacings of the strips in gratings 7 and 8 respectively. The latter, which are spaced from each other, as shown, extend across the whole cross-sectional area of the optical path and are out of focus at the target. Since the lenticular pair 12, 13 change the magnification of lens 6 in one direction only a change in aspect ratios results. If this is not required (e.g. for "wide-screen" presentation) the normal aspect ratio may be restored by means of a second lenticular pair crossed with respect to the first. In this case the two gratings should also be crossed (to reduce interaction between the colour signals) and scanning effected at 45 degrees to the strips of each grating instead of at right angles thereto.
