Title: Improvements in or relating to pressure fluid operated actuators or motors
IPC: F15B15/12
Filed: 1961-04-06
Abstract: 1,023,232. Rotary actuators. A. R. B. NASH. July 6, 1962 [April 6, 1961], No. 12297/61. Heading F1F. An air-operated rotary actuator comprises a piston 14a fixed to a shaft 14 and oscillatable in a working chamber 12, each side of the piston having a sealing assembly consisting of a flexible member 28 made of woven glass fibre impregnated with polytetrafluoroethylene and moulded and sintered to provide around its periphery a flange directed away from the piston, a resilient member 32 of neoprene or silicone rubber to keep the flange against the walls of the chamber, and a rigid sheet steel pressing 34 to hold the other two members in place. The actuator is operated by allowing air to enter one of the ports 40, and opening the other to atmosphere. This may be done by a rotary valve 46 (Fig. 5, not shown), fixed to a magnet 52 located between the poles of an electromagnet (see Fig. 4, not shown). The magnet is spring- biased to a position where the rotary valve allows air to pass to one of the ports 40, and vents the other to atmosphere, but when the electromagnet is energized, the magnet and the valve are rotated to. reverse the connections to the ports 40. The axial thrust on the valve 46 is resisted by a rod 64. The actuator may be bolted directly on to the body of a butterfly valve, to operate the valve (see Fig. 1, not shown).

Abstract: 743,799. Linkwork. DOWTY EQUIPMENT; Ltd., and KNIGHTS, R. N. May 3, 1954 [May 5, 1953], No. 12506/53. Class 80(3) [Also in Group XXIX] A telescopic strut is provided with means for locking the strut in its extended condition. The strut comprises an inner tubular component 14 having a bearing 17 sliding within the bore of a component 10. A locking sleeve 22 is provided in the component 10 and together with a retaining ring 23 defines a groove which is engaged by the heads 32 of locking tongues 33 when the strut is extended. The tongues 33 are spread outwardly by a plunger 38 disposed within the component 14 and slidably mounted on a piston 41 which is fixed relative to the outer component 10. When the strut is nearly fully extended, liquid is supplied through a connection 48 and a tube 46 to a chamber 44 to extend the plunger 38 until a step 55 abuts the heads 32 of the locking tongues which are retained inwardly by the sleeve 22. The plunger thus acts through the locking tongues upon the inner component 14 to assist the extension of the strut. When the heads 32 have traversed the inner surface of the sleeve they spread outwardly into the groove and are retained there by a full diameter surface 39 of the plunger. The strut is unlocked by connecting chamber 44 to exhaust, the liquid permanently supplied through a connection 53 and a passage 51 to the rear of the piston 41 retracting the plunger. The strut is extended and retracted by a hydraulic jack.

Abstract: 276,058. Biscoe, A. E., Stratton, A., and Stringer, H. B. May 17, 1926. Drying materials in long lengths. - Photographic film or paper is dried after development &c., by passing it round and in contact with the surface of a chamber containing hot liquid, while maintaining the sensitized surface outwards in the case of film and inwards in the case of paper; the drying may be assisted by a stream of cold or hot air. The film &c. is fed, after hardening, as in a formalin bath, from a spool 3 preferably first to a squeegee comprising two lips of rubber, and then, over a roller 12 covered with absorbent fabric to remove beads of moisture, to the polished surface of a flanged drum 2, mounted in open-bearings 11, from which it is delivered to a take-up spool 4. The spools and drum are detachably mounted in a casing 1, through which air may be circulated in the direction of the arrows by a fan 5. The air may be heated at, or before reaching the inlet 30, which is preferably covered with gauze to free the air from dust. The ends of the drum are heat-insulated by asbestos, and an aperture in one of them, closed by a screw-cap provides means for introducing hot liquid into the drum. The friction wheels, mounted on a spindle 14 turning in slot bearings in the casing 1, and rotated by a handle 22, are drawn by springs 15 into contact with the periphery of the drum. and the drive is transmitted to the take-up spool 4 by pulley gearing 18, 19, 20 which allows of the necessary slip as film accumulates on this spool. An additional electric heater may be incorporated in the drum, or hot water may be circulated therein through axial passages. Solutions of salts such as sodium carbonate may be used in the drum to obtain a higher maximum temperature. More than one drum may be employed, and for long narrow films such as kinematograph films, a long drum round which the film is wound spirally may be used. Additional rollers may be provided adjacent to the drum to guide the film &c. over a larger are of the periphery of the drum. Reference is made to Specification 275,349, [Class 98 (ii), Photographic processes &c.], in connection with an alternative method for squeegeeing the prints.

Patent GB-597635-A (GB)
Title: Automatic shut-off valve for a hydraulic system
IPC: B64C25/22
Filed: 1944-07-03
Abstract: 597,635. Hydraulic control valves. FIELD, H. July 3, 1944, No. 12652. Convention date, March 5, 1943. [Class 135] A valve for a hydraulic system, such as for operating the flaps and landing gear of aircraft, is adapted to automatically shut off the supply of pressure fluid in the event of breakage of the line between the valve and the operating mechanism. The valve member 9 controls the passage of the pressure fluid from an inlet port 4 to an outlet port 6 and is adapted to be actuated by a piston member 23 which also controls the passage of the return flow from a port 15 to a port 16. The pressure of this return flow is sufficient to lift the piston 23 and open the main valve 9 by means of a rod 12. To enable an operation to start, however, on actuation of a distributing valve, the pressure fluid supplied to port 4 acts on a piston 24 through passages 28, 29 to force fluid on the other side of the piston through a passage 8 to the outlet port 6 which results in a return flow to open the main valve 9. The amount supplied by the piston 24 is limited by its travel so that in the event of a breakage in the supply lines only a small amount of fluid is lost and the valve 9 remains closed, or, if already open, will be closed by the loss of pressure in the return line.

Title: Automatic regulator of the inclination of vehicle headlamps as a function of the load on the vehicle
IPC: B60Q1/115
Filed: 1965-03-25
Abstract: 1,090,298. Electric control systems. P. CIBIE. March 25, 1965 [April 1, 1964; Oct.15, 1964], No.12688/65. Heading G1N. A control system for regulating the inclination of the headlamps of a vehicle in response to variations in the loading of the vehicle comprises, in respect of each headlamp 1, a spiral bi-metal strip 2 fixed at one end 3 and secured at the other end 4 to a rotatable abutment 5 adapted to cooperate with the helical cam track 11 of an axially spring-loaded cam 9. The cam is secured on one end 6b of the core of an electromagnet 6, and the other end 6a of the core abuts an adjusting screw 7 carried by the headlamp, which is pivoted under gravity about a horizontal axis 8. The heating current for the bi-metal strips 2 is controlled by a thermal switch 25 of the type described in Specification 921, 847. When the vehicle is loaded a push-button switch 17 is closed to energize each electromagnet 6 and cause the core to move to the right thereby moving the cam 9 clear of the abutment 5 against the action of a spring 10 and closing a pair of contacts 15, 20 to establish a holding circuit. At the same time current begins to flow through the bi-metal strips 2 and the thermal switch 25 which are connected in series. The switch 25 opens after a time interval determined by the position of a finger 34 carried by an arm 32 which is mounted on the axle 31 and is responsive to the state of loading of the vehicle. After it has first opened the switch 25 will oscillate between open and closed positions, so that the bi-metal strips will soon attain a mean temperature dependent on the state of loading of the vehicle, and the abutments 5 will be rotated accordingly. The relay 13 of a timer 12 opens a switch 14 in the circuit of the electromagnets 6 a predetermined time after the push-button switch 17 is closed, whereupon the springs 10 move the cams 9 towards the left until they meet the abutments 5. The amount of this movement, which controls the angle through which the headlamps 1 are tilted, is determined by the angular position of the abutments. In a modification, Fig. 2 (not shown), the cams (9) are secured on rods (41) which are connected by a cross-member (42) to a shaft (43) fitted with a hand grip (44). When the hand grip is pulled to retract the cams against the force of the springs (10), a contact (45) carried by the shaft (43) closes the circuit of the timer (12) and the bi-metal strips (2) in series with the thermal switch (25) and also energizes an electromagnet (49) which actuates a lock (48) to hold the shaft (43) in the retracted position. When the timer opens the circuit the lock releases the shaft and the cams move back to engage the abutments as in the previous embodiment.

Title: Feeder device for use in bundle tying machines
IPC: B65B35/20
Filed: 1966-03-22
Abstract: 1,086,764. Packaging. BROOKHIRST IGRANIC Ltd. March 22, 1966 [July 7, 1965], No. 12681/66. Heading B8C. Apparatus for progressing a stack, e.g. of newspapers, through a tying device comprises reciprocable pusher means which move the stack to the tying position, stop means movable into the path of the stack to arrest it for tying, means responsive to the movement of the pusher to initiate the tying operation prior to the arrival of the stack at the tying position, and an ejector means to remove the tied stack. The stack is fed to the apparatus by a belt conveyer (2) and trips a limit switch (LS1), Figs. 1 and 2 (not shown), to initiate the stack forwarding and tying processes. Pusher bars 12, 14 are mounted on carriages 4, 6 slidable on bars 8, 10 and are projectable relative to the carriages out of the path of feed of the stack as it is fed into the apparatus and engage behind the stack. Attached to each carriage 4, 6 are stack lead-in guide plates 16, 18. The ejector means 20, 22 comprises carriages similar to the carriages 4, 6 and each having a spring-biased plate 28B, 30B for engaging behind the tied stack. The apparatus is able to tie a stack with a single loop or a pair of spaced loops according to which of the stops 104, 106, 108 is projected into the stack path. If a single tie is required, the machine is preset and passage of the stack over the limit switch (LS1) besides initiating the tying operation and causing the pusher bars 11, 12 to be projected into the stack path behind the stack, causes projection of the stop 104 into the stack path. When the stack reaches the tying position the ejector carriages 20, 22 move in the reverse direction to the stack feed direction, their plates 28B, 30B springing back to enable them to pass behind the stack. The carriages 4, 6 retract and a pressure bar (100), Fig. 7 (not shown), descends to clamp and compress the stack and a tie is made. The bar (100) is then withdrawn and the ejector carriages advanced to remove the completed bundle. When a double tie is required, the sequence is repeated, first with the stop 106 advanced and then with the stop 108, the ejector being used to move the bundle to the stop 108 after the application of the first tie. Hydraulic and electrical circuits providing for fully automatic operation are described, Figs. 8A, 8B and 9 (not shown).
