Title: Improvements in apparatus for controlling the supply of combustion air to a furnace
IPC: F23N1/02
Filed: 1948-02-28
Abstract: 672,115. Fluid-pressure servomotor-control systems. ASKANIA REGULATOR CO. Feb. 28, 1948 [July 9, 1941 ; July 9, 1941 ; July 31, 1941], Nos. 6340/48, 6341/48, and 6342/48. Class 135. The supply of combustion air to a furnace fed with two or more streams of fuel is controlled by means influenced by changes in the fuel streams and adapted to be set to allow for air infiltrating into the furnace or entering with the fuel. As shown, the flows through the fuel conduits 10, 11 are controlled by manually-set valves 9, and the pressure drops across restrictions 13 in the conduits, which drops are a measure of the flows, are applied to diaphragms 16 which act upon pivoted jet pipes 17 loaded by springs 18 adjusted through cams 19 carried by slides 21. The slides are moved through rack and pinion mechanisms actuated by servomotors 25 operated by pressure fluid directed into one or other of the ducts 23, 24. The slides carry pointers 28<SP>1</SP> coacting with scales 29<SP>1</SP> indicating the air required for the combustion of the fuel. The movements of the slides are transmitted through linkage to a differential 35, the output of which, through a rack and pinion, adjusts a slide carrying a cam 39 which loads a spring 48 acting on a pivoted jet pipe 46. The pipe directs pressure fluid into one or other of the pipes 44, 45 of a servomotor 43 for regulating valve 42 in the air duct 12. The air flow is maintained at its set value through a diaphragm 49 subjected to the pressure drop across a restriction 50 in the duct. Allowance may be made for air infiltrating into the furnace or entering with the fuel by adjustment of the profiles of the cams which are formed of plates clamped together on a bolt. Further, the jet pipes are provided with sliders 22, 47, whereby the fuel/air ratio and also the ratio between the air set by the cam 39 and that flowing through the duct 12 may be varied. In a modification, the furnace is fed with, e.g. oil fuel, the supply of which is set through a handwheel operating a rack carrying the corresponding cam and maintained constant by a servomotor controlling a valve in the oil fuel duct, and a supply of, e.g. coke oven gas, which may vary. In another arrangement, the flows of the different fuels may be manually set independently of each other.

Title: Improvements in or relating to fluid pressure jack or like devices
IPC: F15B15/26
Filed: 1934-02-27
Abstract: 434,493. Lifting-jacks. AUTOMOTIVE PRODUCTS CO., Ltd., and BROWN, F. V., Brock House, Langham Street, London. Feb. 27, 1934, No. 6362. [Class 78 (iii)] [See also Group XXXIII] In a jack having a plunger movable axially relative to a cylinder and a piston movable with t he plunger and having a degree of lost motion which is utilized to lock or unlock means for retaining the plunger at the end of its stroke, the piston is double-acting and of annular form and is made fluid-tight relative to the cylinder and plunger by a washer on each end of the piston bearing tightly on the outer surface of the plunger and against the inner surface of the cylinder. The piston 8 provided with cup leathers 9, 10 has a pin 11 which engages a slot 12 in the piston rod 7, the end of which is attached to the member to be controlled which may be the undercarriage of an aircraft. A bifurcated member 17 connected to the piston rod 7 by rivets 20 has laterally extending projections 18 which effect the locking of the piston rod 7 by engaging recesses in the heads of spring-pressed detents 15 mounted on a shaft in the upper part of the casing, and a cam 14 formed at the upper end of a key member 13 secured to the pin 11 opens the detents 15 for the locking and unlocking operations of the piston rod. When the piston, moved upwardly by the admission of fluid, approaches the end of its stroke, the cam 14 which precedes the member 17 opens the detents 15 so that the sides of the members 18 engage the flat portions of the detents. During the remaining portion of the upward stroke of the piston the cam 14 releases the detents 15 for inward movement which takes place when the members 18 are opposite the recesses. When fluid is admitted at the upper end to effect the downward stroke, the piston 8 and cam 14 move downwardly relative to the piston rod 7, and the cam 14 opens the detents 15 to free the members 18 and the piston rod 7 for downward movement which commences by engagement of the pin 11 with the leading edge of the slot 12 in the piston rod. The locking means may be provided at each end of the cylinder. A part of the slot 12 may be helical and the rotary movement between the piston and piston rod may be utilized to effect the locking either by a key or by aligned slots and a plunger. Specification 428,252, [Group XXVIII], is referred to.

Filed: 1935-02-28
Abstract: 452,790. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.- (Assignees of Mathes, R. E. ; 755, Belvidero Avenue, Westfield, New Jersey, U.S.A.) Feb. 28, 1935, No. 6397. Convention date, Feb. 28, 1934. [Class 40 (v)] A thermionic trigger arrangement comprises a single valve having two control grids G1, G4, a grid-anode G2 and a plate anode P. With no signal from S, the control grid G1 is so biassed from - EC and R1 that the electron stream is partially blocked. The grid-anode G2 passes current due to positive bias from +EB through R6, the values of resistances R4, in the circuit of the second control grid G4 and R5, connecting anode G2 and grid G4, being chosen so that the p.d. across R6 produces such a potential on G4 that the anode P passes current which flows through R3. Resistances R1, R2 are such that the potential of G1 is not affected. A positive pulse from S increases current from G2 through R6 and the negative bias on grid G4 is thereby increased, reducing current drawn by anode P through R3. The action is cumulative until current from G2 reaches saturation ; this is the first condition of stability. A negative signal pulse from S causes the converse cycle to occur, anode current from P reaching a maximum and current from G2 a minimum; until the second stable condition is reached. In a modification, Fig. 2 (not shown), the signals are applied to the outer grid G4, the inner grid G1 being connected to the cathode ; resistances R1, R2 are consequently omitted. The grid G4 when positive causes plate current to increase and when negative causes increase in current to the grid G2, robbing the plate current. Values of the resistances are indicated in the Specification.

Abstract: 1,027,866. Threading lead-in wires through lamp caps. PHILIPS ELECTRONIC ASSOCIATED INDUSTRIES Ltd. Feb. 18, 1963 [Feb. 21, 1962], No. 6465/63. Headings H1F and H1J. A method of threading a lead-in wire through an aperture in the lamp cap comprises seating the bulb in a holder with the neck uppermost so as to be capable of universal movement, deflecting the lead-in wire by an orienting member so as to locate the free end in a predetermined position relative to the holder end to produce a bending stress in the wire so as to move the bulb into a new position in the holder in which it is then held while the orienting member is removed and the cap passed over the wire. Preferably, the bulb is held by a partial vacuum while the wire is being oriented, released for movement and again held by the vacuum. It may be subjected to an upward jet of air during its movement. Apparatus for carrying out the method consists of a holder 4 in which the bulb is seated and which has a supply pipe 35 which can be connected alternately to a source of partial vacuum (pipe 36) and a jet 68 of air, by means of a valve 51 controlled by a cam 59. With the bulb held by the vacuum, orienting members 70, 71 are moved into engagement with the wires 2, 3 by means of a valve 80 controlled by a cam 88 coupled with the cam 59. The valve 51 then releases the bulb 1 which is subjected to an upward jet of air from nozzle 68, so that it moves into the position determined by the stress in the wires 2, 3. The partial vacuum is then reapplied and a cap is passed over the wire 2. The method may be carried out on a turret machine, adjustment of the bulb and threading of the cap taking place at successive stations.
