Abstract: 920,230. Centrifugal separators. COOPERS MECHANICAL JOINTS Ltd.,C.M. STREETE, and S. P. WITCHELL. Jan. 19, 1962 [Feb. 7, 1961], No. 4603/61. Class 23. A cyclone for separating solids from gas comprises a vessel 1 having mounted therein an axial outlet tube 6 with an outwardlytapered portion 6 leading out of an untapered portion 5 and not less than twice the length of the untapered portion, and at least one fixed blade 3 which imparts to the gas, as it travels along the blade from its leading edge 2 to its trailing edge 9, a component of velocity which is tangentially directed with respect to the vessel so that the gas is given a whirling motion prior to entering the outlet tube. Three equidistantly distributed blades are mounted on the untapered portion 5 and extend to the inner surface of the vessel. The angle of incidence of the incoming laden gas on the leading edges of the blades may be nil or of small value, e.g. 10 degrees. The blades have a gradually increasing curvature from their leading to their trailing edges so that the tangential component velocity of the gas increases as it travels along the blades. Due to the whirling of the laden gas the solids are separated by centrifugal force and discharged through an outlet 11 in the conical bottom of the vessel whilst the clean air passes through the Venturi. The cyclone may be moulded from synthetic plastic. A number of cyclones may be connected to a common inlet manifold through which their outlet tubes 6 project into a common outlet manifold. The latter may be connected to an air inlet for an I.C. engine, a gas turbine or an air conditioning plant and may be provided with a paper filter. The solids are discharged from the cyclones into a common container. The cyclones may be arranged with their axes horizontal.

Title: Improvements in and pertaining to electro-acoustic sounding apparatus
IPC: G01S1/72
Filed: 1935-02-16
Abstract: 430,150. Echo-sounding and distancemeasuring apparatus. JACQUET, G. G., 47, Rue Cambon, and BADIN, R. E., 16, Rue Nansouty, both in Paris. Feb. 16, 1935, No. 5016. Convention date, March 6, 1934. [Class 118 (ii)] In an echo-sounding system in which the transmission is maintained until the echo is received and transmission is restarted when the echo terminates, the effect of the directly received waves on the receiver is compensated. Two methods of compensation are described, one in which current from the emitter circuit is fed back to the receiver circuit and another in which a second receiver, screened from the echo, acts in opposition to the echo-receiving instrument. As shown in Fig. 1, the output from the oscillator 2 is amplified by valve 3 and feeds transmitter 1, a portion of the current being fed through rectifier 23 to one winding of relay 8. The output of receiver 4, which picks up both direct and reflected waves is fed through an amplifier and rectifier 7 to a second winding of relay 8. The relay 8 is adjusted so that when only direct waves are being received armature 9 is just maintained in contact 10 but when the echo is also picked up armature 9 makes contact 11 which reduces the bias potential on, and so de-energizes, the oscillator 2 to stop transmission. The armature 9 thus oscillates between contacts 10 and 11 at a frequency inversely proportional to the depth being measured and this frequency is measured by meter 16. In the embodiment shown in Fig. 2, a second receiver 4<1>, screened from the echo, is provided and the outputs from the two receivers are rectified by rectifiers 25, 25<1> and fed in opposition to the primary of centre-tapped transformer 28 through interrupter 29. The voltage induced in the secondary of the transformer is fed to the receiving amplifier. This second embodiment could also be used to compensate for other parasitic noises and could be used in conjunction with the embodiment shown in Fig. 1.
