Title: Improvements in or relating to gyroscopic compasses
IPC: G01C19/38
Filed: 1930-09-27
Abstract: 352,335. Gyroscopic compasses. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCHE TECHNISCHE HANDEL MAATSCHAPPIJ GIRO, 142A, Noordeinde, The Hague. Sept. 27, 1930, No. 29014. Convention date, Sept. 30, 1929. Addition to 296,790, [Class 97 (iii), Thermometers &c.]. [Class 97 (iii).] Relates to gyro compasses in which a follow-up member is caused by servomotors to follow the movements of the gyroscope about a vertical axis and about two principal horizontal axes stationary relative to the support, as described in the parent application. The members controlling the current to the servomotors for the follow-up about the horizontal axes are carried by the follow-up member and operate on their servomotors by means of a transformer which distributes the current to the servomotors in such a manner that the follow-up member follows the gyroscope along the shortest path. In the form shown the liquid container 5 is mounted by horizontal pivots 4 in the ring 3 which is mounted by horizontal pivots 2 at rightangles to the pivots 4 in a frame fixed to the support. The ball-shaped gyroscope 13 floats freely and is surrounded by the follow-up member which comprises bowls 9,10 secured by bolts 11 and brackets 8 to a pin 7 rotatably mounted in the cover 6 of the container 5. The follow-up about the vertical axis 7 is effected by the motor 24 mounted on the cover 6 and controlled by the resistance variations in a bridge circuit including the gaps 18, 19 and 18<1>, 191 in the conducting liquid in the container 5 between the conducting faces 18, 18<1> on the follow-up member and the conducting strip 19, 19<1> on the gyroscope carrier 13. The servomotors for effecting the follow-up about the horizontal axes, 2, 4 are controlled by the resistance variations in the gaps between conducting faces 32, 30 respectively on the follow-up member and the conducting strip 14 on the carrier 13. Alternating current is supplied to the strip 14 from the terminal 26 through the conducting faces 25 on the follow-up member and 49 on the carrier. The current taken from the conducting faces 30, 32 is supplied to the poles 38, 39 and 40, 41 respectively of a four-pole transformer. The armature which comprises a slotted drum of laminated iron sheets having two crossed coils 42, 43 at right-angles to one another, may be fixed to the cover 6 whilst the polepieces 38 .. 41 are adapted to rotate with the vertical axle 7. The current from the coil 43 is led after amplification to the servomotor 31 which is mounted on the ring 3 and serves to rotate the follow-up member about the axes 4. The current from the coil 42 actuates a servomotor (not shown) fixed to the main support and adapted to rotate the follow-up member about the axis 2.

Title: Electrical resistance
IPC: H01C1/146
Filed: 1945-11-01
Abstract: 599,895. Wire resistances ; direct connections between conductors. ELEKTROTEKNISK FABRIK VITROHM AKTIESELSKAB. Nov. 1, 1945, No. 29026. Convention date, March 11, 1943. [Classes 37 and 38 (i)] A resistance wire is wound around a core and has its ends secured to connecting wires, the resistance wire also serving for tying the connecting wires to the core. As shown in Fig. 1, a resistance wire 13 is wound around a connecting wire 12 at 14 and then around a porcelain tube 11 and the wire 12 so that this is bound to the tube. Then the wire 13 is wound around the tube 11 to form the resistance element, finishing with a group of turns binding the second connecting wire 15 to the tube 11 and finally a few turns 16 around the connecting wire 15 alone, the resistance wire then being cut off. The resistance may be coated with insulating paper and a layer of copper wire covering the whole of the resistance and serving as a protection and to keep the parts tightly together so as to ensure good contact between the resistance wire and the connecting wires. In a modification, Fig. 2, the resistance wire 13 is wound around a connecting wire 12 at 17 and then a group of turns 18 is wound around the tube 11 and the connecting wire 12. The resistance wire is then led in a few turns to the other end of the tube and a group of turns 19 is wound around the tube 11 and the wire 12. All of these windings serve only to bind the wire 12 to the tube 11, the windings being short-circuited by the wire 12. A layer of insulating paper is then wrapped on and the resistance wire wound over it. Another layer of paper is then wound on and the winding continued for another layer and so on until the necessary length of resistance wire has been wound on. A further layer of paper is then applied and the resistance wire led to the middle of the tube as shown in Fig. 5. The second connecting wire 15 is applied to the tube and the resistance wire 13 is wound over the tube and the wire to form a belt 21, the end of the resistance wire being wound round the wire 15 and then cut off. Finally, the entire resistance is served with a layer of copper wire, the two ends of which are fixed to the protruding ends of the wire 15. The connecting wires may either protrude one at each end of the resistance or both at one end.

Abstract: 1476933 Optical position finding EMI Ltd 30 May 1974 [19 June 1973] 29084/73 Heading H4D A tracking and/or guidance system of the static split detector type, sensitive to energy emitted by, or reflected from a vehicle, e.g. a missile, comprises a telescope 1 which focuses energy, e.g. infra-red, from a beacon mounted on a missile, on to a fibre optic or ground glass screen 2 and has a variable optical system. The disposition of the diffused energy on the screen 2, being indicative of the target position is directed by complex lens system 3 on to a static split detector screen 4 of known type. In order to reduce the physical dimensions of detector 4, for tracking a missile close to the system where the deviation angle may be high, lens 3 is arranged to be physically moved along a track 7 by an electric motor 6 so that it is close to detector 4 when the missile is close to the system. As the missile increases its distance from the system and its deviation subtends a progressively smaller angle from the system axis, lens 3 is moved away from detector 4 until at a predetermined distance it is stopped, whereupon a sharp image is focused on the detector in a known manner. The rate of the lens movement is controlled by motor 6 and programmed to correspond to the missile velocity.
