Title: Method of and apparatus for converting carbon dioxide into a solid
IPC: C01B32/55
Filed: 1924-05-23
Abstract: 237,681. Slate, T. B. May 23, 1924. Solidifying.-Liquid carbon dioxide is solidified by leading it into a chamber having a movable wall under sufficient pressure to cause it to remain liquid during admission, and reducing the pressure within the chamber by the movement of the wall to convert a portion of the liquid into snow. Liquid carbon dioxide is admitted to the cylinder through a valve 33 when the piston is in the lowest position and the lower end of the cylinder sealed by a cap 12. When a certain quantity of liquid has been admitted, the valve is closed, and the piston rises further by its momentum, part of the liquid evaporating and the remainder being solidified. At the end of the stroke, the evaporated gas escapes through holes 28 in the cylinder to a pipe 30 which leads to a suitable carbon dioxide plant. The outflowing gas cools the incoming liquid in the pipe 31 leading to the valve. In its return movement, the piston compresses the snow to a solid cake, the pressure when strong enough opening the cap 12 against the action of spring-held toggle levers 42, 43. The cake is ejected and the levers are returned to position by cam action thus again closing the cylinder. The connecting-rod 19 is pivoted to a lever 20 oscillating on a fixed pivot and actuating a crank 24 through a link 26. The crank-shaft carries a wheel 49 gearing with a pinion 50 on the shaft of which is a fly-wheel 52. The sealing cap 12 is carried by an arm 8 which presses it into position by means of an elastic ring 14 which forms a tight seal. The arm is actuated by the toggle levers 42, 43 held together by a spring 45; the resulting pressure on the sealing cap is adjusted by a set-screw 46. The toggle joint is opened by the pressure of the cake of carbon dioxide, and is closed at the required time by the crank 24 striking a flexible arm 48 on the arm 43. The valve 33 is operated by a rod 36 actuated by an adjustable cam lever 37 struck by rollers 39 on the crank; it is normally held closed by a spring 38.

Abstract: 1,221,451. Fluid-pressure servomotor systems. AVIONS MARCEL DASSAULT. March 15, 1968 [May 8, 1967], No.12804/68. Heading G3P. A tandem electro-hydraulic actuator for controlling the spoilers of an aircraft comprises pistons 1, 2 controlled by respective coupled relay valves 42, 43 which in turn are controlled by flappers 30, 31 connected to the armatures 26, 27 of torque motors 18, 19 having push-pull coils 32, 33 for positional control of the spoilers. Additionally, the torque motors have coils 34, 35 which allow the pilot to switch the spoilers to fully retracted or fully extended positions. Solenoids 8, 9 control valves 10, 11 which shut off the supply of fluid through inlets 14, 15 to the respective nozzles 36, 37 when either flapper is inoperative. Valves 60, 61 function to interconnect opposite sides of pistons 1, 2 when either fluid supply fails. In Fig.2, (not shown), port and starboard spoilers (5g, 5d) are positioned by respective tandem actuators controlled from pilot's lever 50 through amplifiers (Al and A2). Electric switches (V1, V2) sense the magnitude of the error signal input to each amplifier and function to disconnect a faulty side of either actuator and bring the non-faulty side into use. If the latter fails, the feedback is inhibited to both sides of both actuators, valves 8, 9 are energized and coils 34, 35 are energized such as to retract the spoilers. The latter can be subsequently fully deployed by pilot-operated switches.
