Title: Improvements in or relating to gaseous fluid relays
IPC: F16K31/12
Filed: 1951-07-20
Abstract: 705,702. Fluid-pressure servomotor control systems. REGULATEURS FRANCEL. July 20, 1951 [July 21, 1950], No. 17260/51. Class 135 In a gas-actuated servomotor in which the variations of a variable are applied to a baffle interposed in the path of a jet issuing from a nozzle so as to produce corresponding pressure variations in the fluid upstream of the nozzle, the latter is shaped so that the jet is contracted downstream of the outlet from the nozzle and the baffle is located at A ... A, Fig. 4, in this contraction. In an embodiment, the baffle is constituted by a disc or crown cam 46, Fig. 8, carried by a galvanometer 48, and the pressure variations produced in the system downstream of a throttle 55 are applied to a capsule 51 acting on a lever 43 which carries the nozzle 42. After a movement of the cam, the nozzle will thus be reset into a neutral position with respect to the cam. The output of the system is constituted by the movements of lever 43. The cam 46 may be rotated by alterations in the length of a hair when the latter is subject to changes in humidity. When the variable is a temperature, a fluid subject to the latter is contained in a Bourdon tube the distortions of which are communicated to a baffle carried on a lever pivoted at one end. In a system comprising relays, the pressure variations produced upstream of the nozzle 99, Fig. 12, are applied to a diaphragm valve 102 controlling a vent from a bellows 105 supplied with fluid under pressure past a restriction 114a. The movements of bellows 105 actuate a lever 106 carrying a pointer 107 and a recording pen 110, and they are also applied through a link 117 and lever 119 to reset nozzle 99 to the neutral position relative to a cam 98 which is moved by a galvanometer subject to the variable. Lever 106 carries a baffle 131 co-operating with a nozzle 130 to produce pressure variations in a bellows 144 corresponding to variations in the variable, and the movements of the bellows are applied to a lever system 124, 128 to reset nozzle 130 and baffle 131 to neutral position. A screw adjusting means 125 permits of the position of nozzle 130 being pre-set with respect to baffle 131. Lever 124 carries also an inclined abutment 135 which acts on a baffle 137 carried on a spring arm, and subject to the jet issuing from a nozzle 136, and movements of this baffle cause corresponding variations in a pressure fluid supply to a diaphragm motor 150 controlling a valve 148. Nozzle 136 is carried by a bellows 140 also subject to the pressure variations produced by movements of baffle 137.

Title: Improvements in and relating to carburettors
IPC: F02M3/09
Filed: 1924-07-22
Abstract: 238,353. Marks, E. C. R., (Soc. Anon. Etablissements Franþois). July 22, 1924. Spray carburettors.-In a carburettor comprising main and slow speed nozzles, the needle valve controlling the delivery of the main nozzle, and air currents controlling the delivery of both the main and the slow speed nozzles are controlled by a single member. The main nozzle 2 fed from the float chamber 1 is surrounded by a tube 4 provided with spraying orifices 6 and in which slides a valve 7 for controlling such orifices. The valve is bored axially at 8, is loaded by a spring 17 and is actuated by a cam 9 in an airtight chamber 10. The cam is forced by a spring 12 against the side of the chamber 10 in which are formed ports 13, 14. Fig. 3, of which 13 leads through a conduit 15 to the slow speed nozzle 16 and 14 to the atmosphere. With the cam in the position shown in Fig. 3, air from the induction passage 5 passes through bore 8, chamber 10 and duct 15 to the slow-running nozzle, the mixture from which is discharged through duct 18. When the cam is further rotated to uncover port 14 and the throttle opened, air is drawn through port 14 and bore 8 to control the main nozzle delivery. Still further rotation of the cam forces down the valve 7 to cut off the fuel supply, air only being then admitted to the engine.

Title: Improvements in or relating to devices for mechanically controlling a set of pneumatically operated electric switches
IPC: H01H33/32
Filed: 1924-07-22
Abstract: 221,482. Meyfarth, G., and Soc. Anon. des Ateliers de Secheron. Sept. 4, 1923, [Convention date]. Pneumatic actuation.-A device for mechanically controlling a set of pneumatically operated switches is provided with means which prevent all further actuation if any one switch fails to operate correctly. Fig. 1 shows three switches 1, 2, 3 each adapted to be closed by the admission of air into a cylinder 13 through a valve 11 and to be opened by the action of a spring 15 when the downward movement of a rod 10 closes the valve 11 and allows air to leave the cylinder 13 through a valve 12. Rotation of a handle 20 connected to a shaft 6 by a spring clutch 23, a friction clutch 22 and a chain 5, causes the movement to the right of a member 7 a portion 8 of which engages rollers on the rods 10 with the result that the switch 1 is caused to open and after an interval of time the switch 3 is caused to close. Should the switch 1 for any reason fail to open when the member 8 leaves its rod 10 further movement to the right is prevented by the end 9 of the member 7 encountering a rod 19, and any undue stress which might then occur is prevented by the friction clutch 22 or the spring clutch 23. Simultaneous closure of the switches 1, 3 is thus rendered impossible. According to a. modified construction, Fig. 2, the member 7 is replaced by a series of rotatable cams 26 mounted on a common shaft each of which moves a rod 10 up and down as required and has a sector 27 which engages a catch 29 to prevent all further rotation should the switch not open correctly.

Title: Processes for improving the properties of foils, films, fibres or the like made from alginic acid or water-insoluble alginates
IPC: D06M15/423
Filed: 1942-12-10
Abstract: Foils, films, fibres or the like made from alginic acid or water-insoluble alginates are stabilised by treating them with a solution containing a partly condensed formaldehyde synthetic resin which is then hardened to form the finished resin therein. Urea-formaldehyde resin is preferably used in aqueous solution of low molecular weight and in proportion to introduce less than 10 per cent by weight of resin into the alginic material.  Resins from cyanamide, dicyandiamide, melamine, acetoneformaldehyde and phenol-formaldehyde condensation products may also be employed. The treated products are resistant to atmospheric humidity and patterned effects may be produced in them by embossing the treated foils or fabrics prior to the final hardening.  Crimping may similarly be produced in fibres. Opalescent and matt effects may also be produced, and shrinkage reduced by the process. Uncondensed reagents as described in Specification 467,480 may be employed in place of the lightly-condensed resin solutions.

Abstract: 1,043,317. Linkwork. BELL AEROSPACE CORPORATION. April 27, 1965 [April 29' 1964], No. 17716/65. Heading F2K. [Also in Division B7] A linkage provides a temporary overshoot of the control action that is applied to an aircraft control component in response to the pilot's movement of a control element, such as the adjustment of the pitch of a helicopter rotor blade in response to a movement of the cyclic pitch control, so as to compensate for the time lag between the pilot's controlling movement and the response of the aircraft thereto. The linkage comprises an input rod 30 pivoted at 32b to a sleeve 45 in which a lever 32 is slidably mounted. The lever 32 is pivoted at 32c to a rod 34 leading to a dashpot device 36, and is pivoted at 32a to a bracket pinned to an output rod 40 which is axially slidably mounted within a tubular extension 43 of the input rod 30. Movement of the rod 30 by a desired amount causes lever 32 to pivot about 32c due to the resistance provided by the dash. pot 36 and to impart to the output rod 40 a greater movement than is desired. Torsion springs mounted at the pivots gradually restore the lever 32 to its vertical position in which the ultimate travel of the rod 40 equals that of the rod 30. A locking device (Fig. 4, not shown) is provided for locking the rods 30, 40 together in the event of failure of the torsion springs to cancel the overshoot, or in the event of failure of pressure in a servo system controlled by the rod 40 in order to prevent undershoot which might otherwise occur. A shear pin 32N may be incorporated in the lever 32 so that should the damper stick the locking device can be actuated to lock the rods 30, 40 together, whereupon movement of the rod 30 will shear the pin to disconnect the damper.
