Title: Improvements in or relating to apparatus for producing vibrations or pulsations of a fluid
IPC: G10K9/04
Filed: 1938-01-13
Abstract: 509,471. Injectors and ejectors. GAGE, A. M. Jan. 13, 1938, No. 1218. Convention date,. Oct. 20, 1937. [Class 71] [Also in Groups XXXVIII and XII] An apparatus for producing pulsations of fluid, particularly sound vibrations, comprises a chamber having an inlet orifice connected to a source of fluid under pressure, an outlet passage extending into the interior of the chamber and forming an annular seat to co-operate with a light but rigid flap valve which is freely movable to bear alternately upon this seat and another annular seat thereby forming a closure for a chamber containing a fluid under pressure to repel the valve to the other seat, the inlet orifice opening on to the side of the valve which faces the outlet passage. As shown in Fig. 1 fluid under pressure is admitted through an opening 8 controlled by valve 9 to a chamber 2 having an opening 4 closed by a flap valve 5 which in its upper position also closes the outlet 3 to nozzle 1. On increase of pressure in the chamber 2, . the valve 5 moves to its lower position closing a chamber 7 to which fluid is fed at a pressure intermediate between that of the supply to the inlet 8 and that in the nozzle 1. After escape of fluid from the nozzle, the valve moves to its upper position when the pressure in the chamber 2 falls due to fluid passing through the nozzle 1. In a modification, Fig. 2, similar chambers 2, 2a and nozzles 1, 1a are provided on opposite sides of the valve 4 formed with central tapering bosses 10 which facilitate the automatic centring of the valve on its seat in its alternate positions. The inlets 8, 8a to the chambers 2, 2a are fed from the same source of pressure. In a further modification Fig. 3 (not shown), a pivoted flap-valve co-operates with two chambers and nozzles arranged on the same side of the valve and co-operating with inlets to the chambers connected to a common source of fluid under pressure. The device may be incorporated in an injector in which the nozzle for a motive fluid is replaced by a fluid vibrator similar to that shown in Fig. 1 or Fig. 2. As shown in Fig. 7, a fluid vibrator, similar to that described in connection with Fig. 2, is mounted in a chamber having suction inlet 12 and diverging outlets 11, 11 a, the fluid drawn in at the orifice 12 being passed through mixing chambers 13, 13a prior to its discharge from the nozzles 11, 11a.

Abstract: 534,517. Gas manufacture. SURFACE COMBUSTION CORPORATION. Aug. 30, 1939, No. 1399/41. Convention date, Dec. 29, 1938, Divided out of 534,276. [Class 51 (ii)] A method of making a gas for the heat treatment of steel of high carbon monoxide content and controlled hydrogen content consists in feeding carbonaceous material such as charcoal or coke into one end of an externally heated retort, supplying an oxidizing gas to the retort at a point where the carbon is substantially free of volatiles which are driven out of the retort in the vicinity of and in a direction opposed to the incoming carbon and withdrawing the reaction 'products from the retort at a point where the carbon is devoid of volatiles, the hydrogen content of the gas being controlled by controlling the composition of the reaction gas which consists of air, dehydrated flue gas, dried ammonia combustion products or producer gas or mixtures of these gases. As shown in Fig. 1, carbonaceous material is fed into a retort 20 heated by burners 27 from a hopper 15 and solid residues are withdrawn from the retort by a valve 21. The reaction gas is supplied by a pipe 22 and volatiles produced at the upper end of the retort are driven into the hopper and led off through a pipe 17. The reaction products are withdrawn by a pipe 30, 31 which extends down into the retort to a point where the carbon is free of volatiles. Fig. 2, shows a modification in which the reaction products are withdrawn through a port 25 to an externally heated pipe 30' leading to a chamber 34 which may be used for the heat treatment of steel articles.

Title: Improvements in photo-electric methods for the estimation of gases or vapours
IPC: G01N21/85
Filed: 1952-01-17
Abstract: 747,602. Photo-electric gas analyser. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS DE ST.-GOBAIN, CHAUNY ET CIREY. Jan. 17, 1952 [Jan. 18, 1951; March 19, 1951], No. 1407/52. Class 40 (3). In a method of analysing a gas or vapour wherein radiations of the characteristic wavelength which the gas absorbs are passed through it and received on a photo-cell sensitive to these wavelengths the radiations are intermittently interrupted to facilitate amplification of the photo-cell output signal. The interruption of the light may be effected by a mechanical chopper or the light source may be a gasdischarge tube fed from the output of a lowfrequency oscillator. As shown (Fig. 3), light from a source 20 passes through a tube 21 containing the gas under test to a photoelectric cell 22 while a second beam from the same source passes to a second cell 23. Both beams are chopped simultaneously by a rotating perforated disc the output of each cell being amplified and fed in opposition to a meter 30 recording instrument 31 and a relay 32. A filter F2 may be used to limit radiation to the band 3,600 to 4,000Š where a coloured gas is being analysed. The Specification describes a method of detecting moisture (Fig. 5, not shown) in a gas by allowing it to rise through a column packed with Raschig rings into which is fed an oleum from a container. The fog formed by the humid gas then passes through a tube containing further Raschig rings in which excessively large particles are deposited into an absorption tube in which the:unit is detected photo-electrically as already described.. Circuits.-A differential circuit for eliminating source variations from the output is described with reference to Fig. 4. In this embodiment the light source is a high pressure mercury vapour lamp supplied with alternating current. The analysing and comparison cells C 1 and C2 are connected in apposition as shown. A voltage is developed across a potentiometer P1 the output of which is amplified at L1 and coupled to successive amplifying stages L2, L3 by a transformer T1. The voltage developed across a cathode resistor of tube L3 is fed to one grid of a pair of cathode coupled triodes L4, the other grid of which is earthed and a meter, recorder, and relay are connected between the anodes. To eliminate all harmonics of the modulating frequency degenerative feed-back is fed from the cathode of valve L3 through a twin T circuit which passes all frequencies except the fundamental to the grid of tube L2. In the embodiment of Fig. 2 (not shown), a single cell feeds the first amplifying valve and the double triode stage following tube L3 is omitted.
