Title: Improvements in or relating to gas or other fluid meters
IPC: G01F15/04
Filed: 1928-04-21
Abstract: 315,030. Jackson, L. Mellersh-, (Connersville BlowerCo.). April 21, 1928. Counters actuated by revolving mechanism; counters affording several rates of actuation; counting apparatus with variable-step movement. - In a gas or liquid meter of the positive displacement type comprising a casing containing two rotating inter-related lobed elements geared together, the registering or recording mechanism is advanced to compensate for the slippage " of the gas or liquid through the clearance spaces of the meter by means controlled by the rate of flow of the gas or liquid. The gas or liquid, when the flow falls below a predetermined rate, may be caused to pass through a small meter which is geared to the registering mechanism of the main meter in such a manner that the registering mechanism is driven by the faster moving meter. Fig. 1 shows a positive displacement meter 10 in the inlet chamber 31 of which is fitted a valve plate 30 operated through a linkage 33 from a diaphragm 34 subjected on its lower side to the .meter inlet pressure and on its upper side to the meter outlet pressure. During normal working all the gas passes through ports 21 directly to the meter, but when the demand is small the diaphragm 34 operates the valve 30 to close the ports 21 and to open a port 22 thereby causing the gas to pass through a diaphragm meter 26 before passing through the meter 10. The registering mechanism 15 is driven from the shafts 14, 40 of the main and small meters 10, 26 respectively by means of the gearing shown in Fig. 2, including pawls and ratchets 48, 49, and 57, 56 which cause the faster moving meter only to be operative. The shaft 14 of the main meter drives the pawl and ratchet gearing 48, 49 through differential gearing D comprising a central body 60 carrying idler pinions 61 connecting pinions 62 mounted on shafts 43, 44. The body 60 is provided with worm teeth 63 engaged by a worm 64 operated through pawl and ratchet gearing 70, 69 by a gear wheel 42 on the shaft 43. The increased movement of the shaft caused by the differential gearing D is varied to compensate for the variations in the slippage by a masking member 80 which is arranged under the pawl 70 and is operated from the linkage 33 through a link 82. In a modified apparatus, a pivoted flap valve arranged in the gas inlet pipe to the main meter 10 to cause the gas to pass through the meter 26 when the demand is small is raised by the gas flow as the demand increases, the masking members 80 being either operated by the flap valve or by a centrifugal governor driven by the meter 10. In another modification the differential gearing is operated by pawl and ratchet gearing in which the travel of the pawl is varied to compensate for the slippage and in a further modification the differential gearing is dispensed with and the main meter drives the registering mechanism through pawl and ratchet gearing fitted with a masking member operated as previously described.

Abstract: 542,610. Centrifugal separators. BABCOCK & WILCOX, Ltd. July 18, 1940, No. 11863. Convention date, Aug. 12, 1939. [Class 23] Centrifugal apparatus for separating water from steam and applied in a tubulous boiler 12 has a drum 68 with a tangential entry 64, and an outlet for separated water between curved vanes 74 arranged in the annular space between the base 72 and the wall of the drum. The steam outlet 70 is at the opposite end of the drum from the liquid outlet and is surmounted by a canopy 82 which carries a scrubber, or plate steam and water separator 78. The velocity between the whirl chamber and the scrubber is diminished by an annular opening between these two parts forming a passage between the canopy 82 and the drum shoulder 84 through which passes any water separated at this part of the flow. Any such water is deflected downwards by the downwardly extending rim 86 of the canopy. Specification 526,825 is referred to.

[Class 46] A filter having a layer b of fine medium, such as sand, on a layer a of coarser medium, such as gravel, is fitted with a pipe reticulation c below the gravel for the collection of filtrate and the distribution of up-wash water and with a pipe articulation d below the sand for the distribution of air during the up-wash. The wash water is supplied through the filtrate outlet e and the air through pipes f, g. Fig. 2 shows one form of pipe for the arrangement d. The perforations h are formed in separate cupshaped depressions or in a continuous groove in the lower half of the pipe and intermediate the transverse and vertical axial planes, and the pipe is surrounded by a sleeve j with smaller perforations.

Abstract: 1387491 Hydraulic reciprocating pumps or motors ABEX CORP 16 March 1972 [29 March 1971] 12469/72 Heading F1A [Also in  Division G3] In a variable displacement, rotary cylinder block pump or motor, a piston 100 biases the displacement control member 17 towards its zero displacement position with a force which increases in direct proportion to the force applied to the member 17 by the inertia of the working pistons, thereby reducing the force required to adjust the member 17. The adjustment of member 17 may be effected by the servomotor system shown, controlling fluid motors 88, 89 with feedback control (see Division G3), or by manual or mechanical means. The actuating pressure for piston 100 is supplied by a fixed displacement pump 115, e.g. a gear-pump, driven from cylinder block 9 and connected by its outlet to piston 100, and the pump casing interior 123 via throttle 122 to provide the required relationship between the pump speed and the force applied by piston 100.

Abstract: 380,758. Clutches ; change - speed gearing. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT. - GES., (formerly ZAHNRADFABRIK AKT.-GES.), Friedrichshafen, Lake Constance, Germany. May 2,1932, No. 12526. Convention date, May 2, 1931. [Class 80 (ii).] In change-speed gearing, the claw clutches employed are synchronized by plate clutches, the latter being inside hollow gears &c. 3, 4. The gears 3, 4 are supported in a casing 5 independently of a power shaft 1. Clutch plates 6, 7 are splined alternately to the gear 3 &c. and to the shaft 1. A clutch sleeve 2 slidably splined on the shaft 1 has rings of clutch teeth 2<1>. Through the sleeve 2 pass bolts 10 sliding in keyways in the shaft 1. The sleeve 2 is normally coupled to the bolts 10 for axial motion by spring-pressed balls 11, one to each bolt. To entrain the gear 3, the sleeve 2 is thrust to the left, whereby the bolts 10 through a presser ring 9 press the clutch plates together and bring clutch teeth 3<1> in the gear to about the same speed as the clutch teeth 2<1>. Continued thrust on the sleeve 2 causes the.balls 11 to slip clear of the bolts 10, so releasing the plate clutch, while at the same time the clutch ring 2<1> slips into mesh with the ring 3<1>, establishing positive connection.
