Exhaust gases to be purified enter a chamber 1 at 2 and aspirate water from the bottom of the chamber so that the gases are sprayed with water from a nozzle 11, the chamber also containing an inclined baffle plate 9 below nozzle 11 and a perforated plate 8 in the water in the container, the sprayed gases pass out of the chamber into an upwardly inclined passage 15 where they follow a tortuous path between nozzle-shaped members 16 and cup-shaped baffles 17 to an outlet 5. In a modification the gases after being sprayed with water pass upwardly through a vertical passage containing inclined apertured baffles.

Abstract: 1,184,087. Measuring angular displacement electrically. SPERRY RAND CORP. March 22, 1967 [March 28, 1966], No.13366/67. Headings G1C and G1N. The rotor 13, Fig. 1, of a gyroscope 10, rotated about axis 15 by motor 14, has a spherical cavity 11 filled with a fluid which rotates with the rotor but whose axis of rotation deviates from that of the rotor when the rotor axis is rotated. The angular deviation is measured by capacitative differential pressure transducers 24, (25), 26, (27), spaced at 90 degrees round the equatorial plane of the cavity, the pressures being sampled at pairs of ports, e.g. 32, 33 and 36, 37 situated symmetrically either side of the equator. Each transducer comprises a metallic diaphragm, e.g. 40, mounted between metal rods, e.g. 40, 41, the sides of the diaphragm communicating via conduits, e.g. 30, 31, with the fluid. The transducers are fed with signals of frequency WC from source 20, Fig. 2, the signals being displaced in phase by 90 degrees from each other. The output signals from the diaphragms are then added to produce a signal having the form e o = kW (cos Ï cos (W c - #)t + sin Ï sin (W c -#)t) where # is the frequency of rotation of the fluid and Ï the required angular deviation, and fed to amplifier 60. This signal is then compared in demodulators 61, 62 with two reference signals from generator 45 hang the form esin (W c -#)t, e cos (W c -#)t, to produce two D.C. output voltages indicative of the angular deviation in two perpendicular planes. The generator 45 comprises flow quadrantal capacitor plates (50-53, Fig. 3 not shown), forming an annular rotor portion (46) mounted on rotor 13, excited by the same signals as the transducers 24-27, which co-operate with a common annular capacitor plate (54, Fig. 4, not shown) defined by an asymmetrical insulating strip (55) to give an effective capacitative area such that the output signal has the required form.

Abstract: 385,192. Rotary pumps. BECKER, O., 8, Gennebreckerstrasse, Barmen, Germany. May 10, 1932, No. 13429. [Class 110 (ii).] A rotary blower in which the air pressure on the suction side is below atmospheric and which delivers air at, or above, atmospheric pressure, is provided with a passage which connects the working chamber with the atmosphere after the suction port is closed by a valve 8. In Fig. 1, the pump delivers air at atmospheric pressure and passages 14 in each end cover admit outside air into the working chamber for cooling purposes. For silencing purposes the cross section of the two passages 14 is greater than that of a port 17 which admits air into a vessel 16 attached to the side of the pump casing 4. The vanes are pressed outwards by centrifugal force. A non-return ball valve may be arranged in each passage 14. Fig. 2 illustrates a suction and a pressure pump in which the passages 14 have their inner ports 15 situated within the periphery of the drum 6 so that the passages are closed except when grooves 18 in the drum allow air to flow into the working space cut off from both suction and delivery ports. The delivery is increased and the chamber cooled. The invention, which is stated to be used in paperworking machinery, is not restricted to the machines described.

In another example, Fig. 2 (not shown) only that section of the stem which passes through the caseband is of a synthetic resinous material the inner section and the crown being of metal. The crown may however be integral with the section of synthetic material. In another example, Fig. 3, the caseband 12 has a sleeve or pipe 13 through which the winding stem 17 passes. The extremity of the sleeve is located in a groove 16 in the crown which has a metallic coating 15. In another example, Fig. 4 (not shown) the crown is of a synthetic resinous material and has an integral sleeve which is located in a bore in the caseband. In another example, Fig. 5, the crown 26 having a metallic coating 27 screws on to a sleeve 23 extending from the caseband 22. When the crown is in the position shown the surface 29 bears against a flange 24 of the sleeve 23. In the last example, Fig. 6 (not shown) a metal socket is fixed in the crown and screwed on to the winding stem and into a sleeve. The synthetic material used in the above examples may be polyamide, a vinylic resin or a polystyrene.

As applied to ion-exchange loop 10, feed enters from line 1 at 7 into loading section 8 and flows through the bed to outlet 15 thence to waste fluid tank 30, the resin in section 8 having absorbed a component thereof. The resin in section 8 is then rinsed (see below) and moved in part into stripping section 45 by a pulse of liquid entering at 130. In section 45 the resin is regenerated by removal of the sorbed component, and then passes with the next pulse into overflow section 61 where is it backwashed. The rinse fluid which entered at 39 and rinsed section 8 leaves via section 45 and line 70, taking with it the sorbed component removed from the resin.

Abstract: 571,220. Valve-actuating mechanism. CHEMICAL ENGINEERING & WILTON'S PATENT FURNACE CO., Ltd., KERNON, D. R., and PRIEST, E. H. Aug. 20, 1943, No. 13635. [Class 135] Valves 41, 43... 45 are actuated by a timing mechanism comprising tanks 15, 16 connected one above the other so that tank 15 is filled first and determines the timing of the actuation, and tank 16 is then filled and lifts a float 18 which rotates a shaft 24 by means of a pawl and ratchet 23. The shaft carries cams 25 ... 28 which actuate the valves, but, if the valves are electrically actuated, the shaft is formed as a commutator. Liquid flows into tank 15 from a constant head tank 12 past an adjustable valve 13 and a flow indicator 14. As soon as liquid reaches the top of tank 16, a syphon 30 will discharge both tanks 15, 16 into a sump 29, but if tank 15 fills only slowly, a pilot syphon 50 starts the discharge of the main syphon as the liquid approaches the top of tank 16. Valves 41, 43 ... 45 control the supply of liquid to, and its discharge from, chambers 32, 33 alternately. Floats 36, 39 in these chambers carry valves 35, 38 which are thus actuated in timed sequence to divert gas from an inlet 31 to one or other of two filters. The overflow from chambers 32, 33 flows through a seal pot 47 to the sump 29. Valves 41, 43 ... 45 might control the actuation of other types of valves than the flat valves shown. Specification 19063/98, [Class 46], is referred to.

The valve 9 is spring-loaded and opened by a valve plunger 13 connected through a link 16 and on actuating-rod 20 to the slide-valve. The valves are actuated by a pair of spaced levers 31, coupled to the rod 20, which are moved to upper or lower positions by the pistons through springs 36, 37. The levers are retained at either of the extremities of their movement by spring- biassed pawls 42, 43 and are released at the ends of the strokes to move under the influence of spring- pressure by the engagement of lugs 45, 47, integral with the pawls, with the pistons.
