Title: Improvements relating to hydraulic control systems
IPC: B64C13/00
Filed: 1943-08-16
Abstract: 585,389. Fluid-pressure servomotor control systems. HYDRAULIC CONTROL - ENGINEERING CO. Aug. 16, 1943, No. 13294. Convention date, April 16. [Class 135] A hydraulic control system comprises a double-acting servomotor and a valve having an element controlling the flow of pressure liquid to either end of the servomotor, and the liquid coming from-the discharging end of the servomotor is applied to a double-acting motor to actuate a second element of the control valve to shut off the flow of pressure liquid to the servomotor and so provide follow-up for the first valve element. The system comprises a supply tank 5, Fig. 1, pump 7, and accmnulator 3 which supplies liquid through a control valve 1 to one side or the other of the piston of a servo-cylinder 9. The piston is connected to a chain 175 running over sprockets of which one is connected to an aileron 11 or other aircraft control surface or vehicle steering gear. The control valve comprises a casing with a rotary plug 15, Figs. 2 ... 4, to which a handle 33 is secured, and a rotary sleeve 17 carrying a vane 53 which can move between stops 59, 61 in an enlarged part, 27 of the casing.' The sleeve is held in the casing by a set-screw 31 which rides in a groove in the sleeve. If the handle 33 is moved in a clockwise direction, Figs. 3 and 4, pressure liquid flows through grooves 73, 77 and an inter-connecting passage, passages 81, 85, groove 87<1> in the sleeve, passage 95<1>, groove 89<1>, port 127, and conduit 155, to the right-hand chamber of the servocylinder and pushes the piston to the left to lower the surface 11. The liquid in the lefthand chamber of the servo-cylinder is forced out and flows through conduit 157, port 129, groove 89, passage 95, groove 87, passages 97, 99, 100, groove 117, passage 123 and into chamber 175 where it moves the vane and the sleeve in a clockwise direction until the lands 91, 93 on the sleeve cut off the supply of pressure liquid to the servo-cylinder. The vane in moving will force the liquid in chamber 177 out through passage 125, groove 117<1>, passages 115, 111, 139, groove 133, passage 137 and groove 135 back to the tank 5. Movement of handle 33 in an anti-clockwise direction reverses these operations and raises the surface 11. The plug 15 carries a loose disc with an indicating pointer 47 and the handle 33 carries a pin 41 engaging a slot in the disc to give a lost-motion connection which takes up the overlap of lands 91, 93 on passages 85, 97. If vane 53 gets out of synchronism with the handle and rotary plug 15, they can be brought back by moving the handle backwards and forwards to its limiting positions two or three times. During this operation, excess pressure which may develop in one of the chambers 175, 177 is relieved through a valve 107 back.to the supply tank. The servo-cylinder is provided with taps 181, 183 to permit the escape of air when the system is being filled with liquid.

Abstract: 125,626. Chamier, F. W. Sept. 21, 1916. Projectile fuses.-Consists in a percussion fuse having a pivoted firing-pin or striker 3 which is normally turned about its pivot, and which, together with a spring-controlled extensible strikerhead 4, is retained in an inextended and uncocked position until after the projectile is discharged. Fig. 2 shows the fuse in armed condition, during flight of the projectile. A striker rod 6 is normally locked with its head 4 fitting close up to the nose 2, the locking-member being a ball 19 held in place by an inertia sleeve 5. When the rod 6 is thus locked, the firing-pin 3 pivoted thereto lies flat against a percussion cap 22, with the point at right-angles to the longitudinal axis of the fuse. On discharge of the projectile, the rod 6 is released and thrust forward by a spring 7 (the tension of which may be adjustable), whilst the firing- .pin assumes an erect position, as shown. It is locked thus by a spring-pressed plunger 12 having a recess with inclined walls. When impact occurs, the striker-head 4 is driven back, and the firing- pin is driven into the percussion cap. The firing- pin 3 may be replaced by a. blunt-ended striker adapted to co-operate with a spring-preesed pin mounted over the percussion cap 22. The inertia member may be spring-controlled and may be normally locked by a safety-pin. As an additional safety device, a centrifugal obturator, one form of which is illustrated in the Specification, may be provided between the striker and the percussion cap, or between the cap and the detonator.

Title: Improvements in or relating to combustion chambers
Inventor: BARNWELL STEPHEN DOWNING
IPC: F23R3/32
Filed: 1960-04-19
Abstract: 902,511. Generating combustion products under pressure. BRISTOL SIDDELEY ENGINES Ltd. March 27, 1961 [April 19, 1960], No. 13597/60. Class 51 (1). The invention relates to combustion equipment for a gas turbine engine of the kind comprising an outer casing, at least one flame tube disposed within the outer easing, means for supplying fuel to the or each flame tube, a diffusing inlet for delivering air under pressure into the outer casing, means to divide and to guide the air flow into an annular diffusing passage or passages between the outer casing and the flame tube and into a diffusing region immediately upstream of the flame tube, and inlet means for admitting air into the flame tube from the diffusing region. According to the invention, the dividing and guiding means comprises at least one ring, disposed immediately upstream of the flame tube, which is shaped and arranged to direct part of the air flow from a compressor of the engine into the annular diffusing passage or passages between the outer casing and the flame tube and to direct the remaining air flow into the diffusing region, the downstream end of the ring being spaced axially from the upstream end of the flame tube by a short distance so as to allow flow in either direction between the diffusing region and the annular diffusing passage or passages whereby variations of static pressure across a transverse plane just upstream of the upstream end of the flame tube can be substantially equalized. The invention is shown applied in the case of combustion equipment comprising an annular flame tube 1 disposed within an annular air casing formed by walls 9, 10, the upstream end of the flame tube being shaped so as to form a pair of annular troughs 4 within the flame tube and an annular trough 2, 5 outside the flame tube. Fuel vaporizing tubes 3 of J-shape are disposed within the flame tube being secured to the wall 2. Two ring members 14, 15 are disposed in the diffuser passage 11 upstream of the flame tube, the leading edge of the ring 14 being disposed upstream of that of the ring 15. The trailing edges of the two rings are spaced upstream of the upstream end of the flame tube so as to afford annular gaps 16, 17. The rings 14, 15 provide with the upstream end walls 2, 5 of the flame tube an annular diffusing region 8. The rings 14, 15 are mounted on struts 13. Air enters the flame tube through the J-tubes 3, also through inlet openings 7 and 19. Specification 902,510 is referred to.

Title: Improvements in or relating to knitting machines
IPC: D04B15/32
Filed: 1957-04-29
Abstract: 865,177. Knitting-machines. SCOTT & WILLIAMS Inc. April 29,1957 [Oct. 15, 1956], No. 13615/57. Class 74 (2). Automatic stitch control is achieved on a circular machine by a feeler 32 which engages the backs of the sinkers and which causes a baffle-member 48, Fig. 3, to either impede or permit the free flow of pressure air from a nozzle 66. The air in its passage to the nozzle passes over oil in a chamber 192, Fig. 12, which is connected via a shut-off valve 208, Fig. 3, to a chamber 152, Fig. 4, closed by a diaphragm which actuates a piston 148. The piston 148 is coupled to an arm 144 secured to a ring 116 having grooves in its undersurface inclined to the horizontal, which grooves enclose balls 124 between them and similar grooves in the top surface of a second stationary ring 112. These rings are positioned between the needle cylinder and the normal cylinder raising tube 4, Fig. 2. Consequently variation in the position of feeler 32 and baffle member 48 causes the air pressure on the oil in the chamber 192 to be varied with the result that the diaphragm and piston are actuated to turn arm 144 and top ring 116. This turning movement causes the balls 124 to move along the grooves so that the rings move apart or nearer together and consequently the raising or lowering of the needle cylinder. When the correct adjustment has been made the feeler 32 automatically adjusts the baffle member 48 to vary the flow of air from nozzle 66 and stop further movement of the ring 116. The position of baffle member 48 is further controlled by lever 68, the position of which is adjusted as the needle cylinder is raised or lowered by the cylinder raising tube 4. During reciprocatory knitting of the heel and toe the member 68 is withdrawn and a control-member operated from the fashioning cam-shaft holds the arm 144 in a central position and prevents the ring 116 from rotating. In the event of the machine stopping, the shut-off valve is closed to prevent the flow of oil from or to the chamber 152 and the piston 148 is, therefore, held stationary. The size of stitch is thereby retained the same on recommencement of the knitting as that which was being produced when the machine stopped. Specifications 764,694 and 865,178 are referred to.

Classes 80 (1) and 80 (2) In a friction reduction drive from a driving pinion 3 to a driven wheel 4, Fig. 2, frictional contact is normally maintained by mounting the wheel 4 on an eccentric 7 which is acted upon by a spring 8. The drive can be disengaged by readily operable means such as a Bowden cable 9 which can rotate the eccentric against the spring action. The gear is enclosed in a casing 5 having air inlet and outlet apertures 10 for cooling purposes. As an alternative to the eccentric a pivoted arm may carry the driven wheel 4 and the tension of the driving chain may be utilized to maintain the frictional contact. The pinion 3 may be of hardened and polished steel and the rim of wheel 4 of rubber. In Fig. 7 a Vee-belt 14 is used to connect driving and driven pulleys 15, 16 the belt tension being maintained. by a spring-loaded eccentric but being adapted to be released by the Bowden cable 9 to stop the drive. In another arrangement the mounting of the driven pulley is fixed but the pulley is made in two spring-pressed halves to maintain the belt tension. Axial movement of one half relative to the other is effected by an axially arranged push rod and a lever operated by a Bowden cable to free the belt and disengage the drive.
