Abstract: 1,033,454. Lubricating. IMPACO TRUST REG. March 3, 1965 [March 11, 1964], No. 9160/65. Heading F2A. [Also in Division F1] In a rotary-piston compressor comprising an eccentric 3 (Figs. 1, 4, not shown) carrying a piston 8, oil to effect sealing and lubrication is fed from a reservoir 21 through a wick 17 into an air stream in a conduit or channel 16 connected at one end to a chamber 19, which is adjacent a rockable guide-member 12 for a sliding-rocking vane 11 attached to the piston, through an outlet 15 containing a non-return valve and at the other end to a pipe 161 coupled to axial and radial passages 18, 21 in the guidemember, the air stream being established by the pumping action of the vane when the compressor is in operation. Atmospheric air is drawn into the chamber 19 through an intake 34 containing a non-return valve, and the intake may be connected to an air filter 33 (Fig. 3, not shown) for the main intake opening 13 of the compressor. The vane 11 may be provided with grooves 22 (Figs. 5, 6, not shown) in its end faces through which oil flows directly from the chamber 19 to annular grooves 23 in the end faces of the piston. Alternatively, oil is delivered to the grooves 22 from the chamber 19 through channels 24, 25 in the casing and ducts 26 in the vane, wicks 17 being extended from the reservoir 21 to the channels 24, 25, instead of the wick arrangement according to Figs. 1 and 4. Non-return valves 20, 27 prevent air being drawn into the chamber 19 through the wicks instead of the intake 34. Air conveying the oil through the grooves 22, 23 escapes into the working spaces of the compressor. In a further modification (Fig. 7, not shown), the wick 17 projects into the intake 34 externally of a non- return valve 20 therein, non-return valves being lodged in the grooves 22 adjacent the chamber 19.

Title: Improvements in or relating to aircraft flight refuelling apparatus
IPC: B64D39/00
Filed: 1951-04-24
Abstract: 682,375. Flight refuelling apparatus, BOEING AIRPLANE CO. April 24, 1951. [April 24, 1950] No. 9539/51. Class 4. Mechanism for interconnecting aircraft in flight comprises a boom which is supported in the trailing attitude for swinging relatively to the aircraft, control surfaces being mounted on the boom and operable by balancing mechanism connected to the aircraft to move them automatically in relation to the boom as the result of swinging of the latter. In the flight refuelling apparatus shown, the tanker aircraft carries a pivotally mounted telescopic boom 1, the free end of which is fitted with a nozzle 11 and butterfly control surfaces 3, the latter of which, when the two aircraft have been connected. are controlled automatically by pulleys 30, 33 and cables 31. In addition, the surfaces may be adjusted by a manual control lever 55 connected to the pulleys 33 by a further pulley and cable system. The boom is pivoted on the limbs of a yoke 20 provided with a vertical extension 22 permitting rotation about a vertical axis. Assuming the hand lever 35 to remain fixed, swinging of the boom in the vertical plane results in rotation of the pulleys 30 and the control surfaces 3 through equal angles in the same direction, the pulleys 33 remaining stationary. If the pulleys 30, 33 are of equal diameters the surfaces rotate the same angle as the boom. hut any ratio of movement may be obtained by making the pulley diameter ratio of the desired value. Lateral swinging of the boom rotates a crosspiece 23 attached to the vertical yoke member 22, thus rotating in opposite directions arms 4 attached to the casings 40 of differential gear assemblies 37, the output shafts of which carry pulleys 36 connected by cables to the pulleys 33. The latter thus rotate the surfaces 3 through equal angles in opposite directions. Fore-and-aft movement of the lever 55 causes rotation of a differential 53, coupled to quadrants 51, the movement of the latter being transmitted by pulleys 5 and the differentials 37 to the pulleys 36, 33 to move the surfaces 3 through equal angles in the same direction. The quadrants 51 are turned in opposite directions by the differential planet pinion 54 if the lever 55 is moved transversely, whereby the surfaces 3 are turned through equal angles in opposite directions. The arms 4 are connected to the crosspiece 23 by links 41, the points of connection of which with the member 23 are adjustable to vary the ratio of control surface movement to that of the crosspiece 23.

Title: Improvements in coin controlled vending machines
IPC: G07F11/58
Filed: 1937-04-05
Abstract: 495,186. Coin - freed article delivery apparatus. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., and TURPIN, G. W. April 5, 1937, No. 9543. [Class 27] In a coin-freed vending-machine in which articles are stored in pockets on a motor driven endless conveyer, insertion of a coin and displacement of a button or the like as a selected pocket approaches a fixed point, together with the subsequent return movement of the button, effects ejection of the article from the selected pocket, whilst finally leaving the conveyer in motion ready for a further actuation. As shown, article pockets 16 open at the top and front are pivotally supported on brackets 15 bridging a pair of endless chains 1 extending round pairs of sprocket wheels 3, 4, 5 and 6. Each pocket is closed at the bottom by a spring-actuated pivoted flap 17, and has a rearwardly extending roller which enters guides 28 at the delivery position. Sprocket wheels 4 are fast with a diametrally slotted disc 29 adapted to be engaged by a bolt 31 actuated by a solenoid 34. An electric motor normally maintains the conveyer in motion. When the selected pocket reaches a position between the lines 51 and 52, the operator presses a button 36. This breaks the circuit of the motor and energizes solenoid 34 to stop the conveyer. Moreover, the inserted coin is released from a temporary support, and momentarily closes the circuit of a second solenoid which releases a catch 42 allowing a bolt 38 to be projected by a spring 41. Upon release of button 36, the conveyer is restarted, and a rearward projection on the closing flap of the selected pocket strikes the end of bolt 38 so that the flap is displaced and the article in the pocket released into a delivery shoot 45. An abutment 54 on the rear of the pocket then returns the bolt into locking engagement with its catch 42. According to the Provisional Specification, the conveyer is set in motion by insertion of a coin, whilst subsequent depression of the push-button stops the conveyer, and ejects the article from the selected pocket by means of a cam surface at its inner end which tips the closure flap of the pocket. Alternatively, the conveyer may be driven continuously and the push-button be locked by coin-freed mechanism.

Abstract: 697,757. Gas turbine plant. LUCAS (INDUSTRIES), Ltd., J. April 22, 1952 [April 25, 1951], No. 9613/51. Class 110(iii) [Also in Group XXIX] The supply of liquid fuel to a jet propulsion engine or a gas turbine is regulated by a liquid operated servo-mechanism controlled by a device m comprising two co-axial ducts i separated by a gap, and an occulator or baffle j movable transversely across the gap, the rate of flow through the ducts i being also controlled by one or more normally open valves each responsive to a variable condition. As shown the spring-loaded servo-piston c controls the inclination of the swash-plate b of a variable delivery pump a. One end of the servocylinder d is supplied directly from the pump delivery r through a passage g and the other end is supplied through a conduit h and a series of control means 20, 19, 22, 24 and finally through the control device m containing the occultor j. This occultor is actuated by a spring-loaded diaphragm k subject on its upper side to a pressure related to the speed of the pump and supplied from a radial passage q in the pump rotor. Each control means comprises a normally open valve such as 12 operated by a spring-loaded lever such as 15. The control means 19 is responsive to atmospheric air pressure acting on an evacuated elastic capsule 16. The control means 20 responds to variations in the temperature of the combustion chamber which affect for example the length of a rod 21. The control means 22 responds to the pressure drop across a throttle w in the main fuel supply, this pressure drop acting on a diaphragm 23, and the control means 24 is similarly responsive to the pressure drop across a manually operable throttle s acting on a diaphragm 25. The throttle w is actuated by a servo-piston x under the control of a normally-closed valve 4 operated through a lever 5 by an evacuated elastic capsule 9 responsive to blower delivery pressure. The lever 5 is loaded by springs 6 one of which is connected to the throttle w.
