Title: Improvements in and relating to measuring instruments
IPC: G01R1/02
Filed: 1931-03-16
Abstract: 375,316. Measuring instruments. JEFFREE, J. H., University College, Oxford. March 16, 1931, No. 7967. [Class 118 (ii).] In instruments of the type in which the deflection of the moving part is detected by the displacement of a beam of light or other suitable radiation reflected from a mirror fixed thereto, the displacement is relayed by directing the reflected beam on to electrically opposed thermojunctions c, Fig. 1, in circuit with coils a rotatably suspended in a magnetic field. Normally the radiation falls symmetrically on the opposed junctions c, no current flowing in the coils a. Deflection of the beam causes unequal heating of the thermojunctions and consequent rotation of the coils a in a direction corresponding to the beam deflection. The amount of rotation is limited (1) by balancing the electromagnetic torque against a suitable restoring torque the median line m of the thermojunctions in this case being disposed in the suspension axis b, or (2) by disposing the median line m, Fig. 3, in front of the suspension axis b, the coils a rotating until the beam d again falls symmetrically on the junctions c. In (1) the rotation is, for small displacements, approximately proportional to the displacement of the beam d and to its illumination intensity and in (2) proportional to displacement of the beam d but independent of the illumination intensity of the latter. The amount of rotation may be observed by any suitable means as a pointer and microscope but preferably the beam d is partly received on a mirror fixedly mounted with the coils, the reflected beam therefrom forming an optical pointer for the moving system. An instrument for case (2) above comprises a copper wire loop a, Figs. 4 and 5, suspended between magnetic poles N, S and core R, from a quartz fibre b fixed with shellac to the back of a mirror f to which the prolongations p of coil a are similarly fixed. The opposed thermojunctions are formed by a suitably blackened constantan disc c to which bent copper wires e are soldered and connected at their other ends to the loop a at g, h, thereby positioning the thermojunctions in front of the suspension axis b, Fig. 5.

Patent GB-597926-A (GB)
Title: Improvements in or relating to high speed water and land vehicles
IPC: B60F3/00
Filed: 1941-06-30
Abstract: 597,926. Endless-track land and water vehicles. HAMILTON, R. M. June 30, 1941, No. 8237. [Class 79 (i)] [Also in Group XXXIII] A ship which can travel on land comprises a body 13 having a number of vertically-movable supports 12 for water-tight endless track or tracks 11 which is or are broad enough and stiff enough laterally to spread the load so that when the vessel is travelling at speed it can roll over the surface of the water, the track and movable track-supports being free to set themselves in a configuration which conforms to the resistance offered by the water. In the construction shown, the vessel comprises a series of cars 13 articulated together at 14 and provided with wheels 12 over which runs the endless track 11. The cars are further connected together by hydraulic jacks 18, 19 spaced apart from the joints 14. The jacks 18 are vertically above the joints 14, and when they are locked the train of cars is rigid so far as up-and-down movement is concerned. The jacks 19 are located at the sides of the cars and can be used to effect steering of the vehicle by extending those on one side and contracting those on the other. Each car has a motor 37 driving wheels 20 which engage the rims of the wheels 12 either frictionally or by means of gear teeth. The wheels 20 are mounted on axles 21 connected by links 23, 24 to the axles of the wheels 12 so as to be unaffected by relative movements of the cars and wheels. Lateral doors 25 are provided on the cars and corridor doors 26 at the ends. When the vessel is travelling on the water with the jack 18 free, the vessel tends to assume a sinusoidal form depending on the speed, and when the speed is steady can be locked in this form by locking the jacks 18. When the jacks are not locked they act as vibration dampers. The jacks are controlled by the driver or navigator by means of electro-magnetically operated valves. Steering of the vessel may be effected by (1) the jacks 19, (2) a rudder, or (3) by using two tracks side-by-side and driving them at different rates. Endless tracks; paddles. The track comprises short-rail sections 30 carried in chairs 29 on sleepers 28. The rails may be held in the chairs with a rubber liner permitting a small amount of freedom without necessitating a hinged joint. The sleepers are secured to transverse spring members 27 of considerably greater length and the whole track is covered by flexible material 15. The margins of the tracks are controlled by arms 31, 35 having counterweights 36. When the vehicle or vessel is at rest on the water, the springs 27 and arms 31, 35 take up the position shown in broken lines in Fig. 3 and thereby assure sufficient buoyancy. When the vessel is moving at sufficient speed the front end, at least, will ride on the surface and the springs 27 &c. will take the position shown in full lines. Paddles 16 are hinged to the cover 15 and their outer edges are connected by endless cables 17. On the lower run the paddles hang downwards and tend to grip the water.
