Title: Multiplex signalling system
IPC: H04J9/00
Filed: 1944-06-20
Abstract: 590,472. Multiplex wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 20, 1944, No. 11746. Convention date, Sept. 29, 1942. [Class 40 (v)] Multiplex signalling is effected by separately modulating different portions of carrier frequency energy from a common source and then effecting relative phase displacements of the modulated carrier waves before transmission. Fig. 1 shows the arrangement at the transmitter. Carrier wave energy from source 10 is modulated at 14 with a first signal programme from 18, and at 16 with a second signal programme from 20. The modulated carriers are fed to transformer primary 24 by lines TL1, TL2, having a difference in length such as to introduce a phase difference of 90 degrees. The combined signal, radiated from 30, comprises in effect a carrier which is modulated in amplitude and in phase by each programme. Also the phase modulation is 90 degrees ahead of the amplitude modulation for one programme, and 90 degrees behind theamplitude modulation for the other programme. Thus, if the phase modulation components are obtained and shifted 90 degrees, then their addition to the amplitude modulation components will give one programme, and subtraction will give the other programme. This is achieved in the receiver, Fig. 3, in which the I.F. output from 42 is fed to a frequency discriminator 46 and an amplitude detector 48. The output of 46 feeds a valve 60 having its load impedance high compared with condenser 64 at audio-frequencies. Then the voltage across 64 corresponds to the phase modulation envelope of the carrier input and in 90 degrees phase shifted relative to the voltage applied to the grid of 60. This voltage is fed in push-pull to the grids of valves 52, 54. The amplitude modulation components are fed from 48 in phase to the grids of 52, 54 and thus the outputs of the respective valves, being the sum and difference of the inputs, comprise the respective first and second programme signals. Specification 489,094 is referred to.

Title: Improvements in or relating to vibratory massage
IPC: A61H23/02
Filed: 1926-05-06
Abstract: 252,000. Brillouin, L. N. May 6, 1925, [Convention date]. Massage.-Mechanical vibrations of audible or ultra-audible frequency for massage treatment are applied to the body through a liquid in which the source of vibrations is immersed. The vibrators employed are of various known types operated by alternating electric currents, and may be arranged so as to concentrate the vibrations at a desired point within the body, in which case the current used has a frequency of at least several thousand cycles per second. The current employed may be produced by an alternator, an arrangement of thermionic tubes, a Poulsen arc, or otherwise. The vibrator, which is immersed in water or other liquid serving to transmit the vibrations to the body, may be of telephone receiver type wherein a diaphragm, with or without an attached armature 5 of soft iron as shown in Fig. 2, is operated by an electromagnet, or may be of electrostatic type comprising parallel plates 6, 7, Fig. 3, separated by a dielectric. The vibrating plate 6 is supported peripherally by the metallic box 8, whilst the fixed plate 7 is connected by a conductor 9 passing through an insulating block 10 to the source of current. A third type of vibrator may utilize the piezo-electric properties of quartz. Fig. 4 shows such an instrument wherein a plate of quartz 11 is arranged between conductors 12, 13 connected to the high frequency circuit. The vibrating conductor 12 is held peripherally by a box 14 filled with air or an insulating liquid. In a modification, Fig. 5, the plate of quartz 11 is held between two steel elements 16, 17 of which the outer element 16 is in contact with the liquid which serves to transmit the vibrations. In order to concentrate the vibratory effect a number of vibrators 18 - - 21, Fig. 6, may be mounted in a spherical shell 22 so that the synchronous vibrations arrive in the same phase at the centre 23 so that the individual effects are superimposed. By varying the phase of the different vibrators, concentration may be obtained at a point other than 23. Fig. 7 shows an arrangement in which a vibrator 25 is placed on the axis of a mirror 24 immersed in water so that the vibrations may be concentrated at a point 26. Two mirrors 24 as shown in Fig. 7, or two multiple vibrators as shown in Fig. 6, may be arranged so as to have a common point of concentration.
