Title: Improvements in apparatus for sounding, or signalling comprising a gaseous discharge lamp
IPC: G01S15/10
Filed: 1927-09-21
Abstract: 279,803. Soc. de Condensation et d'Applications MÚcaniques, and Touly, M. Oct. 28, 1926, [Convention date]. Determining distances acoustically.-In apparatus for the acoustic determination of depths and for signalling low-voltage electric discharge lamps containing low-pressure gas and having two or more electrodes are lighted or extinguished by the application of an over or under voltage at the moments of emission and reception of the compression wave. The luminous discharge starts and stops at well-defined potentials, the stopping potential being lower than the starting potential. An electric discharge lamp 6 which may be a neon lamp having its electrodes covered with alkaline earth, is arranged in circuit with a source 7, a potentiometer 8, a transformer 5 and the armature 10 of a relay 9, the winding 11 of which is connected to a switch 3 through a condenser 12. Highfrequency current from a transmitter 1 supplied by a source 2<1> is converted by a piezo-electric condenser 2 into ultra-audible waves, the reflected impulses being also received and re-converted by the device 2, which is connected through an amplifier 4 to the transformer 5. At the moment of emission the switch 3 is closed, the condenser 12 discharging through the relay 9, which opens the lamp circuit and extinguishes the lamp 6. The discharge time of the condenser 12 is greater than the time of emission. When the echo returns, the energy from the amplifier 4 and transformer 5 applies an over-voltage to the lamp 6 sufficient to light it, the lamp remaining alight until the emission of the next signal. The dark interval may be measured by mounting a mirror 55 and a lens 56 on an arm secured to a rotating shaft 54, an image 57 of the lamp 6 being thus displaced around a circular graduated scale 58. By using the resistance 7<1> and the connection shown in broken lines, and by regulating the voltage of the battery 7 by means of the potentiometer 8, the emission and reception of the signal may be used to apply an under. voltage and extinguish the lamp. The switch 3 and the relay 9 may be actuated mechanically by the same device, for example by two cams on the shaft of the motor driving the shaft 54. In a modification the lamp is arranged to give flash signals, coupling between the amplifier 4 and the circuit of the relay lamp being established by autotransformers, condensers, resistances, &c. A lamp with an auxiliary external electrode or magnetic field may be used for starting. In a further modification a relay in the lamp circuit controls an electric timing device in another circuit.

Filed: 1945-08-24
Abstract: 620,508. Radio navigation. O'BRIEN, W. J. Aug. 24, 1945, No. 24989/46. Divided out of 620,481. Drawings to Specification. [Classes 40 (v) and 40 (vii)] This invention relates to a multiple-channel radio receiver such as is described in Specification 620,481, and the description in the two Specifications is substantially the same. The claims are directed to a receiver for receiving and determining the multiple phase relation of a plurality of unlike but harmonically related frequencies comprising circuits for coupling each channel of the receiver to a single antenna, each coupling circuit comprising a radio frequency transformer tuned to the frequency to be received by the associated channel, the voltage transformation ratios of the coupling circuits being in the same ratio to each other as the frequencies to which each is tuned and the relative degrees of coupling of the transformers being substantially equal. Coupling circuits complying with this requirement are used to make the phase changes in the coupling circuits due to random variation in antenna capacity equivalent and of no effect on the multiplephase relationship determination. In the embodiment described the tuning capacities in the coupling circuits are all made equal and the Q's of the transformer windings are in the same ratios as the frequencies to which each is tuned. Specifications 620,479,620,507, [Group XXXVI], and 631,735, also are referred to.

Abstract: 756,409. Coil Springs. WOODHEAD & SONS, Ltd., J. Sept. 3, 1954 [Sept. 9, 1953], No. 25643/54. Class 108 (3). [Also in Groups XXII and XXX] An idler for the conveying run of a belt conveyer conprises a helical spring made of wire which, during its formation into the coiled state, is subjected to both a tensile stress in the direction of the axis of the wire, and a twisting stress about the axis of the wire, so as to cause the coils to become pre-stressed radially and axially together. In Fig. 1, the wire, as it is wound on a rotating mandrel 1, is subjected at 9 to a tensile stress in the direction of its axis and simultaneously at 10 to a twist as denoted by the arrows 11. The degree of tensile and torsional stress is within one quarter of the tensile and torsional breaking stress, respectively, of the wire. In Fig. 2, the upper run 30 of a conveyer belt is supported by pre-stressed rollers 12, whilst the lower run is supported by open-coil non-prestressed rollers 23. The end convolutions of the springs forming the rollers 12 are secured to endplates 13 on spindles 14. The latter are rotatably mounted in casings 15 provided with lateral pins 16 engaging in recesses 17 formed in the jaws of bifurcated supports 18 mounted on members 19. The ends of the springs forming the rollers 23 are welded to hubs 24 fitted with spindles 25 mounted in a similar manner to the spindles 16. Accumulation of dirt in the rollers 23 is prevented by inserting loose balls 33. In a modified construction of roller for supporting the return run, Fig. 3, the end convolutions 34a of the spring 34 are compressed together and hubs 35 are helically grooved so that they can be screwed therein. Clogging of the roller by dirt is prevented by a rubber hose 37 filled with water. Alternatively, an air inflated tube or a solid insert of sponge rubber may be used. Specifications 756,410 and 756,411, [both in Group XXX], are referred to.
