Abstract: 518,073. Retractable undercarriages. AIRCRAFT COMPONENTS, Ltd., and BOUND, R. H. July 19, 1938, No. 21440. [Class 4] In a retractable aircraft undercarriage or nose or tail wheel support, the operating-jack &c. is connected by a lever to the swinging leg of the undercarriage, a projection on the lever'engaging a guide on the fixed part of the aircraft in such a manner that in one position, the swinging leg is locked and on operating the jack, the projection moves along the guide until the lever contacts the leg when both move together. In one form, the jack 24, Fig. 1, is connected to the telescopic shock-absorber leg 10 carrying the landing-wheel by a lever 20, a cross-head on which engages curved slots in the bracket 15 to which the leg 10 is pivoted. In the position shown, the link 20 forms the locking and supporting strut for the undercarriage. On operating the jack, the cross-head moves along the slot until its axis is in alignment with the axis of the pivot of the leg 10, an abutment 27 on the lever simultaneously engaging an abutment 28 on the leg 10, when further movement operates the leg. In a second form, the supporting bracket 15, Fig. 4, is provided with two curved slots 33A, 33B concentric respectively with the pivot 32 of the leg 10 and with the pivot 35 of a lever 36 on the leg. The jacks 24, Fig. 5, are pivoted to arms 38 fixed on the same pivot as the lever 36 and pins 39 in the arms 38 engage the slots 33A, 33B. The undercarriage is locked when the pins 39 are in the upper end of the rest 33B. On operating the jacks, the lever 36 moves until it contacts the leg. In a third form, Fig. 6, the operating-jack is con-. nected to one end of a single or double lever 42 mounted on pivot 43 on the leg 10 and having a pin or pins 44 engaging a slot concentric with the pivot 43. In this case, retraction of the leg takes place when the pin or pins 44 are moved into a position when they are concentric with the pivot of the leg 10. In the application to the undercarriage described in Specification 484,938, the jack 63, Fig. 7, is pivoted to one element of the breakable strut and is connected through a link 54 to a link 57 on the other element, a pin 55 on the link 54 forming in this case an abutment and engaging. a slot 59 in the element 49, and a corresponding slot 62 forming an extension of a curved slot 61 in a bracket on the other element 48. In another form, Fig. 9, the jack is connected to a lever 68 pivoted to a bracket on one arm of the breakable strut and having a pin 71 forming the abutment and engaging a curved slot 72 on the other element of the strut. A modification is shown in Fig. 10 in which the ends of a lever 74 are pivoted to the jack 63 and to one of the elements 48 of the strut, a pin 77 on the lever engaging a slot concentric with the pivot 75 of the lever.

A cylindrical muzzle 62, surrounds the needle 59, and extends at least to the tip of the needle. The skin of the patient 63, is impaled on to the needle by a vacuum source via a tube 21, connected to the muzzle. The means by which the preparation is released comprises a bellows 22, a piston 25, which reciprocates along the axis of the bellows, one end of the piston being in communication with the wall 36 of the bellows and the other end extending beyond the bellows and being slidingly engaged with the interior wall of a measuring chamber 58. The bellows are caused to contract and expand by alternately connecting them to the vacuum source (the same as that which is connected to the muzzle) and then to the atmosphere. The vacuum in the muzzle 62, and the bellows 22, is released by a trigger mechanism 6, which aligns a channel 14, from the vacuum source with a channel 15, leading to the atmosphere through the trigger. The volume of the dose is varied by a thumbscrew 24, which regulates the stroke of the piston and thus the volume of the measuring chamber 58.

Title: Hydraulic actuator controls
IPC: F15B11/02
Filed: 1972-05-10
Abstract: 1361680 Fluid-pressure servomotor systems SPERRY RAND Ltd 21 July 1972 [23 July 1971 10 May 1972] 34557/71 and 21725/72 Addition to 1335041 Heading G3P [Also in Division F1] An actuator 116, Fig. 1, is controlled by a main control valve 80 and a pilot valve 42 which controls the fluid-pressure for operating the valve 80. A motor 40 applies a first force proportional to an electrical signal to the spool 48 of the pilot valve, and a shuttle valve 140, which is responsive to the pressures in the actuator 116, applies an opposing force to the spool 48. In addition the main valve 80 is controlled by a second pilot valve 12 which is itself controlled by an electrical input to a motor 11 and an  opposing signal from a flow-sensing device 322. The two pilot valves are in series and either one may be set to over-ride the other. With the piston 120 moving to the right it may happen that the pressure P 1  may exceed the pressure P 2 . Under these conditions the shuttle valve 140 would cause the main valve to close further thus increasing the difference between P 1  and P 2 . Fig. 8 shows a modified circuit which overcomes this. In this circuit shuttle valve 440 is responsive to the pressure difference across the main valve 80 rather than across the actuator 116. Since the pressure in line 156 leading to the chamber 46 is not necessarily the higher of the two pressures P 1 , P 2 , the pressure in this line is no longer suitable for controlling a variable volume pump. The pump control line 145 is therefore connected via an auxiliary shuttle valve 460 to whichever of the ports 104, 106 of the valve 80 is at the higher pressure.
