Title: Improvements in return steam traps
IPC: F24D19/08
Filed: 1931-05-02
Abstract: 376,871. Steam traps ; feedwater supply apparatus for steam boilers. ROYLES, Ltd. and ROYLE, A. G., Dalham Engineering Works, Irlam, near Manchester. May 2, 1931, No. 12968. [Classes 64 (ii) and 123 (ii).] In a return steam trap comprising a bucket float i in a collecting vessel a, a siphon pipe j discharging water from the bucket float into the boiler, and a double beat valve operated in accordance with the movement of the float and controlling the admission of steam under boiler pressure, the float operates a pilot valve m which, in conjunction with a leaky piston n, controls the movement of the double beat valve. Normally the float is in its raised position and the pilot valve is open to allow boiler steam from the inlet e3 admitted above the piston n through a passage g<1> to flow through the aperture n<1> in the piston and then through the pilot valve into the body of the trap, which is then vented to the atmosphere through a passage e<1> and port e<2>. When water overflowing into the float causes it to sink, the pilot valve is closed, and the pressures of opposite sides of the piston being balanced, the steam pressure lifts the valve f thus closing the exhaust port e<2> and opening the passage e<1> to the steam port e3. The water in the float is then discharged through the siphon pipe into the boiler. When the trap is arranged above a water collecting vessel under variable pressure, the exhaust e<2> is open to the atmosphere through a valve operated by a piston upon opposite sides of which act the pressures in the trap and in the collecting vessel, and the valve is loaded to maintain a constant pressure difference between the trap and the collecting vessel. Specifications 117,351, [Class 64 (ii), Heating systems &c.], and 207,582, [Class 135, Valves &c.], are referred to in the Provisional Specification.

[Class 82(ii)] In a heavy media sink and float separation process the particles of different specific gravity and varying over a wide range in size are introduced into a single separatory fluid, which has sufficient upward current to ensure the removal of light floating particles with the overflow, at such an angle that the particles have a horizontal component of fall at least equal to their vertical downward component, the heavy particles of such size and mass that their vertical downward component rapidly becomes greater than their horizontal component are arrested at a level immediately below the zone at which the principal separation occurs and removed from the vessel, the remaining small heavy particles being collected at the bottom of the vessel. As shown a conical vessel 1 filled with a separatory fluid has mounted on an axis 18 parallel with and above the surface of the fluid a truncated conical rotatable screen 16 having pockets formed by plates 21. The feed enters from a chute 5 opposite to an overflow and the large heavy particles are removed by the screen 16 and deposited on a conveyer 24. The small heavy particles drop to the bottom of the cone and are removed by an air lift 12. Guide plates 29 may be provided to remove floating particles from the vicinity of the screen and direct them to the overflow. The rotating screen may be replaced by a stationary catenaryshaped screen, the large heavy material being removed by an endless rake Fig. 4, (not shown) or bucket shaped sieves mounted on a continuous conveyer Fig. 5 (not shown) or a continuous arrangement of small hinged trays Fig. 6 (not shown) may be used.

Apparatus for counting a succession of articles comprises a member movable in timed relationship with means for moving the articles, indicating or signalling means operated by the member and means for detecting gaps in the succession of articles and for correcting the indicating or signalling means. Cardboard blanks 1 are moved by pushers 3 on a conveyer between a photo-electric cell 4 and a lamp 5 surrounded by a shutter 6 rotated in synchronism with the conveyer and having slots 7 so that light only falls on the photo-cell when a blank is absent from a feed position on the conveyer. A shaft 13 is geared to the conveyer so as to rotate once per one hundred feeds and is connected to one member of a bevel-wheel differential gear 14. Whenever a blank is absent, the planet-wheel carrier 20 of this gear is advanced one step by a solenoid 21, energized by a relay circuit controlled by the photo-cell, and actuating a pawl 26 to advance a ratchetwheel 25 geared to the planet-wheel carrier 20. The shaft 15 of the differential gear is thus rotated once per hundred blanks fed and a cam 16 thereon closes contacts once per revolution to actuate a visible or audible signal 19. The ratchet-wheel 25 is braked by a friction-plate 29. The planet-wheel carrier may alternatively be directly actuated by the pawl 26.

[Also in Division G6] A device for limiting to a predetermined value the flow rate of a fluid in a conduit, comprises a convergent-divergent tube interposed in the conduit and having a minimum cross-section at its throat portion. The object of the invention is to limit the flow of the fluid or gas in the case of accidental rupture of a part of the circuit, and also to preserve a sufficient volume of gas for cooling purposes. In Fig. 3 the conduit 4 is protected by the throat portion of the Venturi tube 1, 2, 3 which is constructed so that the gas flow is subsonic in the normal state, but during a rupture is limited to a maximum value which is sonic. In addition to the upstream Venturi tube another one may be disposed downstream of the protected conduit. A mechanism for adjustment of the throat portion cross-section i.e. the needle-valve 9, can be combined with the Venturi in order to regulate the flow by throttling. However a shaped body, (Fig. 4, not shown), may be located axially in the conduit to give this effect.
