Title: Pressure control for variable pressure boiler
IPC: F22B35/10
Filed: 1975-07-29
Abstract: 1521972 Pressure control in variable pressure steam boilers J W CARTER Snr and J W CARTER Jnr 29 July 1975 31626/75 Heading F4A A steam boiler of water tube construction (preferably a monotube boiler such as can be used in vehicle power plant) has a throttle valve 11 to vary the steam pressure output and a pressure differential sensing means 36 located across the valve to operate a combustion fuel control for the boiler; the sensing means being designed at a particular throttle setting to maintain a set pressure differential across the valve 11 as well as to prevent a dangerous build-up of boiler output pressure. As shown in Fig. 2 a drum member 16 having an aperture 17 and rotatably movable on a fixed drum member 18 with an aperture 19 can be adjusted by a motor 29 (via a belt 31) to increase or decrease the boiler air supply which enters via the apertures and has a cam 20 which acts via follower 22 and cable 26 to simultaneously adjust a fuel valve assembly 28. The sensing means 36 comprises a cylinder 37 supported for axial movement, a fixed piston rod 41 fast with a small piston 53, a large piston 49 loosely located on piston 53 for limited axial movement thereon, and spaces on either side of piston 49 which are interconnected via the throttle valve and high and lower pressure steam lines 65, 67. The pressure differential tends to urge piston 49 to the right against the force of spring 61 and an attached rod 50 acts on a spring element 76. Movement of the element 76 to the right closes switch 35 to turn member 16 in a direction to decrease boiler combustion air and a lever arrangement 84, 85 secured to member 16 pivots bracket 74 at 79 (on which switch 35 is mounted) away from element 76 to open switch 35. The magnitude of the fuel and air response is therefore directly related to the magnitude of the differential and relative longitudinal adjustment of levers 84, 85 controls this magnitude. Reduction of the differential causes the spring 61 to move piston 49 to the left and element 76 to close a switch 34 to turn member 16 in the reverse direction. In addition to the movement of the piston a sufficiently large boiler output pressure (on line 65) causes the whole cylinder to move to the right against a spring 37 and this will act to close switch 35 and reduce boiler air and fuel.

Title: Differential pneumatic linear dimension comparator gauge
IPC: G01B13/08
Filed: 1954-11-08
Abstract: 782,691. Pneumatic linear-dimension gauges. FORTIER, A. Nov. 8, 1954, No. 32222/54. Class 106 (2). A pneumatic linear dimension gauge whose operation is independent of the pressure of the air supply comprises a casing 1, 2 having two chambers 10, 12 separated by a flexible diaphragm 3 operating a dial indicator 28 and disposed between a pair of perforated concave members 36, 37, the diaphragm being substantially non-elastic and of such surface area that it can conform to the concave surfaces without tension. A source 14 supplies compressed air through a passage 4 which is connected by ports 7 to the chamber 10 and by ports 5 to the chamber 6, and through a passage 11 connected by ports 13 to the chamber 12, there being two inlets 16, 17 and two outlets 23, 19, the outlet 23 being controlled by a valve 27a operated by the diaphragm, which may be of thin leather, and the outlet 19 being disposed at a short distance from the object 21 to be gauged. The dimension of the object 21 to be gauged determines the pressure in the chamber 12 and if this exceeds the pressure in the chamber 10 the diaphragm 3 will move upwards, acting on the rods 33, 27b so that the valve 27a will decrease the escape of air through outlets 23 and 26, raising the pressure in the chamber 10 until there is equilibrium. Thus the reading of the dial 28 connected by a rod 30 to the member 27a is a function of the dimension. A weak spring 31 keeps the member 33 in contact with the diaphragm 3. In another embodiment an additional outlet is provided which may be used in conjunction with a series of calibrated nozzles to permit comparison within a number of ranges of measurement. In place of the dial gauge 28 a rack and pinion device engaging a series of micro-switches which operate a corresponding series of lamps may be incorporated to indicate whether the dimensions of objects placed on the bracket 20 are within, above or below specified limits. Fig. 5 is a cross-sectional view of a cylindrical gauging head with diametrically opposed openings in place of the members 19, 20 of Fig. 1 for checking the internal diameter of a ring. By connecting a further gauging head at 22 the gauge can be used for checking angles of conicity. The valve 27a can be modified to control the inlet of air to the upper chamber.

The spindles are rotatable in bearings 11 on a plate 12 extending above the conveyer 2 and are upwardly urged by springs 16 abutting gears 17 so that the spherical upper ends of the spindles engage thrust bearings 21 in arms 22 ; the gears 17 engage gears on a shaft 19 continuously driven by a bolt from a motor. The arms 22 are, at one end, pivotted to a shaft 22a and, at the other end, provided with replaceable pins 28 of the same diameter as the abrasive sticks, the pins being arranged in similar echelon formation to the spindles. When the pins engage cutaway portions 5a of the templates of the same area as that to be mottled on the components, the respective arms pivot downwardly to urge the abrasive sticks into engagement with the components. The conveyers are driven intermittently by a pawl-and-ratchet mechanism 30, 31 driven by a cam 32 on a shaft 26. During the movement of the conveyers, further cams 23 on a shaft 26a driven from the shaft 26, upwardly pivot the arms 22 to enable the springs 16 to disengage the abrasive sticks from the components. The chucks 14 may be fixed or freely mounted on the spindles to enable uneven surfaces to be mottled and the abrasive to wear uniformly.

Abstract: 412,844. Arc lamps. PARFITT, A. W., Stafford House, Norfolk Street, Strand, London.-(Tappan, C. ; 420, West End Avenue, New York, U.S.A.) Nov. 23, 1933, No. 32744. [Class 39 (i).] Relates to a control arrangement for an A.C. arc in which the electrodes 10, 11 are adjusted by means of a motor M under the control of a relay. The arc is fed from the secondary winding 7 of a transformer T having a high leakage reactance, an additional secondary winding 8 supplying the motor M and a relay R through a rectifier C. When the arc current falls off, due to the leakage reactance, the voltage across the winding 8 increases and the current through the relay R rises to a value sufficient to operate the relay and cause adjustment of the electrodes by the motor M. In a modification, a clockwork motor is used, in which case the relay R operates a brake. In another modification, the rectifier C is supplied from a current transformer connected in the supply to the arc. In this case reduction of current in the rectifier circuit causes actuation of the relay to complete the motor circuit. The primary of the current transformer may be shunted by a resistance.
