Title: Improvements in or relating to control valves
IPC: F16K1/42
Filed: 1941-01-29
Abstract: 544,524. Valves. BRITISH THERMOSTAT CO., Ltd., and BUSH, E. J. Jan. 29, 1941, Nos. 1183 and 16318. [Class 135] A valve device having a lift valve member opened by fluid pressure acting against an adjustable loading spring has the valve seat yieldmgly mounted and the closing movement of the valve member limited by a flange on the valve engaging a shoulder on the casing or by the valve member engaging a flat seat surrounding the yielding seat. As shown in Fig. 1, the valve member has a facing of deformable material such as neoprene and is loaded by a spring k adjusted by a screw m having a packing r. The yielding seat comprises a nipple f adapted to move through a central aperture in a flat seating surface o. The nipple is formed on a piston d having a packing e and lifted by a light spring t and inlet pressure admitted through the main inlet passage b. In a modification, the seating has a facing of deformable material and co-operates with a knife-edge seat on the lower end of the valve member. The cylindrical surface of the valve member is provided with a packing and has a flanged part adapted to provide an abutment for the loading spring and also to co-operate with a shoulder on the casing to provide a stop. In this form the loading spring is housed in a sleeve screwed into the casing and formed with a recess co-operating with a fixed pin whereby its movement is limited. The movement of the seat towards the valve member is limited by engagement of the piston with a ported extension on a detachable part of the casing. Strainers are fitted in both inlet and outlet

Title: Improvements in or relating to steam-heated heat exchangers
IPC: F28D3/04
Filed: 1963-01-10
Abstract: 1,036,451. Tube heat exchangers. ESCHER WYSS A.G. Jan. 10, 1963 [Jan. 10, 1962], No. 1190/63. Heading F4S. [Also in Division B1] In a steam heated evaporator or other fluid heater in which the heat absorbing fluid flows through vertical or inclined tubes, 5, extending through a chamber 4, the heating steam is passed into the chamber through one or more inlets 10 above a partition 9 which extends across the upper part of the chamber transversely of the tubes. These pass with clearance through corresponding holes in the partition. From the steam inlets 10, tube-free passages 13 lead to the interior of the chamber, giving uniform distribution of steam throughout the upper chamber. In the part of chamber 4 situated below the partition 9 the tube free passage is filled by a displacement body. The steam flows from the upper chamber through the clearance left between the tubes and the partition, down into the lower chamber; the condensate leaving via the tube 12, and any air contained in the steam leaving through steam venting pipes 11. The medium to be heated or evaporated circulates through the tubes as shown by the arrows, leaving the space 6 and flowing upwardly through the pipes 5, to the space 7, returning through the central tube 8 to the space 6.

Filed: 1941-01-30
Abstract: 544,384. Returning leakage liquid. KAMMER, G. S. Jan. 30, 1941, No. 1246. [Class 102 (i)] [Also in Group XXVII] Leakage of fuel in injection nozzles or other apparatus subjected intermittently to high liquid pressure is collected in a chamber communicating through a non-return valve with a closed space of resiliently variable volume. this space being connected through a further non- return valve with the inlet for fuel. Fig. 1 shows an injection valve 22 supplied with fuel by a pump connected to passages 6 8 and 10, leakage of fuel past the valve collecting in a chamber 25 and flowing past a non-return valve 29 to a space 37 closed by a resilient body 32 of synthetic rubber or the like. When the fuel pressure in the inlet 6 is relieved, the fuel in the space 37 passes through holes in the valve 29 into a passage 36, opening another non-return valve 16 and returning by a passage 14 to the inlet 6. In modifications the non-return valves may be of the ball type, and the resilient body 32 may be replaced by a diaphragm or a corrugated capsule.

Title: Improvements in or relating to loading devices for molding presses
IPC: B29C43/34
Filed: 1943-01-29
Abstract: 565,216. Feeding preforms to moulding presses. STOKES MACHINE CO., F. J. Jan. 29, 1943, No. 1562. Convention date, Jan. 19, 1942. [Class 87 (ii)] Preforms which are to be moulded between multiple dies 1b 2b on press platens 1, 2 are carried into the press by a wheeled carriage 5 running on tracks 3. The carriage supports a loading board comprising two superposed apertured plates 9, 8 which are slidably connected together by pin-and-slot means. When the loading board is out of the press, as shown in Fig. 1, the apertures in the plates 9, 8 are out of registry and the preforms are disposed within the apertures in the upper plate 9. The carriage is moved into the press and near the end of its inward movement two things happen simultaneously : (1) The wheels 6, 7 of the carriage drop into notches 3a, 3b in the tracks, the carriage and loading board thus descending and the apertures in the lower plate 8 being brought into alignment with the dies 2b. (2) The forward edge of plate 8 abuts a stop 10 on the press (Fig. 3) and the plate stops. As the wheels ride down into the notches a rear carriage frame member 5b abuts the rear edge of plate 9 and pushes it forward, plate 9 thus sliding over plate 8 and the apertures in the plates being brought into registry, whereupon the preforms drop through the apertures into the dies 2b. The carriage and loading board are then retracted, leaving the preforms in the dies. A cover-plate may be placed on plate 9, to prevent the preforms bouncing out. Instead of preforms, loose material may thus be carried into the press. The press cannot be closed until the carriage is in its extreme " out " position, as shown in Fig. 1. In this position, the carriage closes a switch 20 to complete the circuit to a relay 18 which may then be operated by a switch 19 to operate a valve 16b which admits pressure fluid to the hydraulic cylinder 16 of the press. As the carriage advances to the " closed position, a scraper 12 thereon dislodges previously moulded articles (buttons) from the upper dies or ejector pins, and a jet of air from pipe 13 blows articles out of the lower dies into a receptacle. Specifications 534,753 and 536,437 are referred to.

Title: Improvements in and relating to operating furnaces
IPC: E05F1/06

Abstract: Fuel composition for use in furnaces, e.g. blast furnaces, comprise a slurry of coal having a "nominal particle size" of 1/16 to 3/8 inch in fuel oil having a vixcosity of 75-1000 SFS at 122 DEG  F., the coal constituting 40-70% by weight of the slurry.  By "nominal particle size" is meant that the majority of the particles have a size approximately equal to the nominal size.  In use, the slurry is maintained in an agitated state at a temperature of at least 150 DEG F., and is thus in a pumpable state.ALSO:Furnaces, particularly blast furnaces, are fuelled at least partly by a slurry of coal in a fuel oil having a viscosity of 75-1000 8 FS at 122 DEG F., the coal having a nominal particle size of 1/16 "\ba-3/8 " and constituting 40-70 weight per cent of the slurry. The slurry is heated to a temperature of at least 150 DEG F. and agitated before introduction into the furnace, and may be injected either into the hot air stream blown through the tuyeres of the furnace preferably through a lance into the tuyere opening, or directly into the furnace through the wall proper. The slurry replaces part or all of the normal coke charge in the furnace, preferably the former.
