Title: Improvements relating to speaking radio beacons
IPC: H01Q25/00
Filed: 1953-02-23
Abstract: 734,625. Radio navigation. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Feb. 23, 1953 [Feb. 23, 1952], No. 4999/53. Class 40 (7). In a speaking radio beacon of the kind in which a bearing statement is transmitted by means of an antenna having a sharply directive mechanically or electrically rotatable pattern and a covering field of the same frequency and modulated by an audio frequency is transmitted by a second aerial system radiating in directions other than that to which the first antenna is for the time being directed, the covering field signal is amplitude modulated by the audio frequency and phase-modulated by a frequency which is preferably above the range of audibility. It is explained with reference to Figs. 1, 2 and 3 (not shown), how the effect of the frequency modulation is to prevent errors due to the combination of directly and indirectly received waves at the receiver. The speaking beacon to which the invention is applied may be similar to that described in Specification 686,886 and have the same aerial system. Signals from a master oscillator 26 may feed frequency multipliers 27 and 28 and modulators 29, 30 to which are applied the speech modulation from unit 31 and which are connected to aerial arrays 32 and 33 for transmission of the sharply directed speech-modulated signals. Phase modulator 34 is also fed from oscillator 26 and receives a modulating signal of, say, 20 kc/s. from generator 35. The phase-modulated output is fed through frequency multiplier 36 (having the same multiplication factor as units 27 and 28) to amplitude modulator 37 fed with an audiofrequency signal from unit 38 and then to the aerial system 39 radiating the covering field.

Filed: 1941-04-21
Abstract: 585,332. Gas turbines ; air compressors. GRIFFITH, A. A. April 21, 1941, No. 5152. [Classes 110 (i) and 110 (iii)] Bladed discs for gas turbines, such as described in Specification 585,330, and the like, which are mounted for individual rotation on a stationary shaft, are balanced axially by differential air-pressure loading on the sides of the discs. Discs 12 individually mounted on ball-bearings carry air-compressor blades 14 and turbine blades 16. Air from the high pressure end of the compressor is admitted to the hollow stationary shaft 10 and, through holes 19, to the spaces between the discs. The areas over which this pressure is applied are determined by packings 20-24 and these areas are such as to produce the necessary axial pressure. In another form, the hollow space of each disc is provided with vanes which cause the air therein to rotate with the disc. A pressure gradient due to centrifugal force is thereby set up and the opposite exterior sides of a disc are subjected to different pressures by means of holes in the disc walls at different positions in the gradient.

Title: Improvements in or relating to Audion or Lamp Relay or Amplifying Apparatus.
Inventor: LATOUR MARIUS
IPC: H03C1/16
Filed: 1917-04-16
Abstract: 127,318. Latour, M. April 15, 1916, [Convention date]. Telephonic relays. - High-frequency currents, such as are usad in wireless telegraphy and telephony, are amplified by vacuum-tube relays in combination with iron-core transformers, the transformation ratios of which are of determined values calculated from the constants of the vacuum tubes and their circuits. In order to prevent arcing in the tubes, the potentials of certain elements of the relay, for example, the transformer coils and cores, are fixed by connecting them to points on the supply battery. Fig. 3 shows a pair of vacuum tubes 1 arranged for a double amplification, the input circuit being connected across the primary of the transformer T', the secondary of which is connected to the grid 3 and filament 4 of the first tube. The plate circuit of this tube includes a source P and the primary coil of a transformer T<2>, the secondary being connected to the grid 3 and filament 4 of the second tube, the plate circuit of which is supplied by the same current source P and is connected by a transformer T<3> to the receiver circuit R. Each tube has four characteristic constants, viz. : the rates of change of the grid current when the plate potential is constant and the grid potential is slightly varied, and when the grid potential is constant and the plate potential is varied ; and the corresponding rates of change of the plate current. The transformation ratios are calculated in terms of these constants and of the resistances of the receiver circuit R and the input circuit, in such a way as to obtain the maximum relay effect, i.e. the maximum ratio of energy liberated in the receiver circuit R to energy consumed in the input circuit. The potential of the transformer cores M<1>, M<2>, M<3> and of one primary terminal of the transformer T<1> is determined by connexions to any point. of the battery P. The metal parts of the telephone receiver in the circuit R may be connected to the positive pole of the battery P. One form of transformer is shown in Fig. 4, in which the core is formed of two side members c and three cross-members a, b, the coils being wound around the central cross-member a, The cross-section of the parts b, c is equal to, or greater than, that of the central part a, so as to reduce the flux density in the external portions of the magnetic circuit. The primary coil Y is intermediate the two sections X, Z of the secondary coil, and a space e is left between the outside of the coil X and the core arm b. The coils may be formed of successive cylindrical strata several millimeters apart, and each stratum may consist of two layers of similar wire connected in parallel so as to reduce the resistance without increasing the capacity. The core is built up of thin sheets of silicon iron or of iron annealed in vacuo. The transformers may be placed in copper or aluminium casings to avoid magnetic leakage from one transformer to another, and the potential of these casings may be defined.

A toy comprises a figure 13 seated on a vehicle and containing a drive mechanism which produces movement of the legs of the figure, thereby operating pedals which drive the toy. The figure contains a battery driven electric motor 26 having a drive shaft 29 and worm 30, by means of which a vertical shaft bearing is operated via a gear 31. Matching cam lobes 36, 37 are secured to the portion 35 of the shaft 32. Crank arms 42, 43 carry pairs of cam followers, crank arm 42 being associated with cam followers 38, 39, and are fixedly mounted on a crank shaft 48. Each crank arm drives a leg of the figure up and down. The head of the figure is moved from side to side by means of the movement of a vertical rod, the horizontal portion 49 of which is attached to crank arm 43 by a bracket 50. The legs of the figure are pivoted at the knee and are moved up and down alternately. Each foot is attached to a pedal of the vehicle, the pedals being fixed on axles 98, 103. Up and down movement of the pedals drives forward the wheel 65 which is supported on an axle 62, by means of a ratchet and pawl arrangement. The pedal support member 96 is attached to a disc 79 which has extending from it a disc 85 on which is pivotally mounted a pawl 89. When the pedal is moved downwards the pawl end is held in connection with the ratchet wheel 75 by a biassing spring 92, driving the vehicle forwards. At the same time, the pawl end 78 of the other pedal, which is being raised, is disconnected from the ratchet wheel 74. In a modification, the vehicle comprises a wheeled hobby horse, which is driven along the ground by direct engagement between the ground and the ball portion of the feet of the figure.
