Title: Improvements in or relating to devices for regulating the fuel and combustion air feed in burners or furnaces
IPC: F23D14/60
Filed: 1953-06-26
Abstract: 742,375. Burners. ADRIANOFF, A. June 26, 1953 [July 1, 1952], No. 17847/53. Class 75(1). [Also in Group XII] A device for the simultaneous control of the fuel and the combustion air intakes in a burner or furnace comprises an intermediate member connected between the air valve and the fuel valve and provided with a plurality of parts each of which can be adjusted in situ for a corresponding one of a series of positions of the fuel valve to determine a corresponding optimum setting of the air valve and being so constructed that the air valve moves without discontinuity and without oscillation from one setting to the next. The intermediate member shown in Fig. 2 consists of a slotted plate 11 connected to the shaft of a valve controlling the flow of fuel to a burner so that when the shaft is rotated by hand or by a servo-motor the plate moves linearly. Two screws 13 are adjustably secured in each of the slots of the plate and carry vanes 14 forming a continuous path for a roller 16 on the end of a rod 17 connected to a butterfly valve in the air supply duct of the burner. In another embodiment the intermediate member comprises a shaft carrying a plurality of radial fingers which are adjustable in length and direction and which abut in turn against a pivoted plate connected to a butterfly valve controlling the air supply. The shaft is connected by an eccentric drive or by a connecting rod and crank to a sprocket driven by a servo-motor or hand-wheel and the sprocket is also connected by two adjustable rods to the fuel valve. In the burner installation shown in Fig. 6, liquid fuel is supplied by a pump 51 through a pressure. regulating valve 52 to an atomizer 56 and the delivery of the atomizer is regulated by a valve 57 controlling the return flow of excess fuel from the atomizer to the intake side of the pump. This excess fuel is also conveyed to a cylinder 59 to move a spring- returned piston carrying a rod 71 having a plurality of fingers 72 of adjustable length which abut in turn a rod 74 actuating a butterfly valve controlling the air supply. A leaf spring 73 ensures that the fingers slide over the end of the rod.

Title: Improvements in or relating to valve gears
IPC: F01L27/04
Filed: 1924-07-30
Abstract: 228,789. Simmen, O. July 30, 1924. Combined fluid-actuated and mechanical or electric gears.-A hydraulically-actuated distributing-valve is raised by liquid acting on a piston connected thereto against the resistance of a spring. The liquid is continuously delivered by a rotary or other pump to the piston chamber which is provided with an intermittent-closing, electromagnetically-operated, outlet valve. The outlet valve l works in conjunction with a subsidiary valve p which controls the main outlet from the piston chamber. The fluid passing the valve L is thereby reduced in quantity, and the valve l can be of small dimensions. The liquid under pressure enters the passage i, passes to the space beneath the valve l through ports q, and presses the valve p down against the resistance of a spring r thereby opening passages n leading to the main valve piston chamber. When the valve l opens, the fall of pressure above the valve p allows the spring r to raise the valve to engage a shoulder s and open an outlet o.

Title: Improvements in or relating to machines suitable for use in the manufacture of shoes
IPC: A43D25/06
Filed: 1963-05-10
Abstract: 1,038,033. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. May 10, 1963 [May 16, 1962; Nov. 9, 1962], No. 18500/63. Heading A3B. A shoe-bottom pressing machine comprises a pad box 14 which is movable heightwise by a piston and cylinder C1 to press a shoe on its last and a sole positioned on the shoe bottom against toe and heel abutments 24, 26, and a kick off arm 34 operated by a piston and cylinder C2 which ejects the shoe when the pressure applied by the pad box is released. The machine is controlled by an automatic control circuit (Fig. 3, not shown) which has a valve V1 which supplies compressed air to the cylinder C1 in one position and to the cylinder C2 via a valve V2 in its other position. The valve V2 is held in closed position by the pad-box 14 when in its lowermost position and is opened by a spring when the pad box is raised. Initially the valve V1 is in the position shown with both C1 and C2 inoperative. On moving the valve V1 pressure is supplied to the cylinder C1 for a time determined by a timing device T1 in which air is allowed to escape from a chamber 48 through a restriction R1 until the diaphragm 42 moves across to shift a valve V4 which moves the valve V1 to its other position. This causes the pressure to be released from the cylinder C1 and pressure to be supplied to the valve V2 which, since the pad box is still raised, is in its open position to supply pressure to cylinder C2 to operate the kick-off arm. When the pad box reaches its lowest position valve V2 is closed and the kick-off arm returns to its initial position. The circuit also includts an emergency release valve V3 which will reelase the pressure in the cylinder C1 In a modfiication (not shown) a valve V22 (corresponding to valve V2) is opened by a cam on the pad box when the pad box is rising or descending, pressure being supplied to the valve V22 only when pressure is released from the cylinder C1, i.e. when the pad box is descending.

Abstract: 613,401. Detachable hose couplings. BAILEY, A. June 20, 1946, No. 18567. [Class 99 (i)] A hose coupling which can be rapidly coupled and uncoupled by manual manipulation comprises two similar coupling members having projections on their contacting faces which engage on relative rotation, spring-pressed axially projecting locking bolts on each member for engaging holes in the other, and pushbuttons in the holes for disengaging the bolts. One only of a pair of identically similar coupling members is shown. This member comprises a short metal tube 1, the end 2 of which receives the hose, a washer 4 of water-tight flexible material, and a metal collar 5 fitting over the tube and engaging a flange 3 thereon. The washer is shaped to engage the tube end as shown. The collar has a plurality (two shown) of equally spaced projections 7 undercut to form wedge-shaped teeth at their extremities so that when the two collars of a coupling are rotated, the teeth are interlocked and the washers 4 drawn together. Each collar has as many equally spaced spring bolts 8 as it has projections 7, and each bolt (Fig. 5) is mounted in a bore in a projection by means of a spring 11 and grub-screw 12, a shoulder on the bolt engaging an enlarged part 10 of the bore to prevent the bolt from dropping out. The collar also has one hole 13, Fig. 4, which receives one of the bolts when the collars engage. In the hole is the head 18 of a stem 17 attached to a push-button 14 so that, when the coupling is to be disengaged, manual pressure on the button will move the bolt out of the hole 13 and allow rotation of the collars.

After the MoO 3  has been reduced to molybdenum dioxide, the mixed solids 11 are fed to the second furnace zone, running at 800-900C where the molybdenum dioxide or oxide mixture present are reduced to a metallic product 13, which may be crushed, and rebriquetted to produce a surface bonded compact of Mo or ferromolybdenum with discrete particles of the elements. The preferred composition contains 30 wt per cent iron, with less than 7, preferably 0-2, by wt per cent oxygen, and has a specific gravity of 4À5-7. The preferred reductant 3, hydrogen from cracked ammonia is fed countercurrent into zone 2 of the furnace together with recycled gas 5 as feed gas 9. A portion of the gas leaving zone 2, 15, is dried and recycled to give input gas 9 a 50:50 H 2  : N 2  composition, the remainder of the gas from zone 2 being fed 17 into zone 1 to reduce the MoO 3  to MoO 2 . The preferred starting materials are particulates within the size range minus 20 to minus 325 mesh, and the mixed oxides may result from the preroasting of MoS 2  and FeS 2 , or by the mixing of MoO 3  with mill scale.
