Title: Fluid operated rotary-linear actuator assembly
IPC: B23B47/22
Filed: 1970-06-15
Abstract: 1317030 Draw bar operation EX-CELL-O CORP 15 June 1970 [25 Sept 1969] 28852/70 Heading B3B [Also in Division F1] A fluid operated device for producing linear and rotary movement of a draw bar 27 of a boring spindle comprises a stationary part 51 and a rotatable part 11. Linear movement of the draw bar 27 results in retraction of the tool cutter radially as shown in U.S.A. Specification 3,391,585. Rotation of draw bar 27 effects a radial motion of the tool to compensate for wear as is also shown in the above U.S. patent. The latter part 11 includes a cylinder assembly 31 having a piston 35 which can be moved to the right, Fig. 1, to effect linear movement of draw bar 27 by means of a projection 37 of the piston 35 which slides in shaft 25. This shaft 25 has vanes 47 which can be subjected to fluid pressure to give an incremental rotation to the shaft 25 which is transmitted to the draw bar 27 via an overrunning clutch 29. The stationary part 51 and the rotatable part 11 are coupled by a shaft 49 which is a press fit in a manifold 41 attached to the cylinder assembly 31, this shaft 49 thus rotating with part 11 in a bore in the stationary part 51. If high pressure is applied to a part 53 in part 51, fluid flows through a bore 54 in shaft 49 and forces piston 35 to the right to move draw bar 27. Fluid also passes through passages 38, 39 in the piston projection 37 to chambers 68 on one side of vanes 47. This serves to hold the vanes against stops 59 to prevent rotation. Fluid drains from chamber 69 to the right of piston 35 through passages 34, 44, 43, 42, 40, 48 to port 55 and exhaust. If high pressure is applied to port 55, fluid flows through passages 48, 40, 42, 43, 44, 45 to chamber 46 on the other side of vanes 47. Thus vanes 47 move against springs 70 to rotate shaft 25 and draw bar 27. Fluid flows from chambers 68 through passages 39, 38, port 54, and to exhaust.

Patent GB-519891-A (GB)
Title: Improvements in or relating to multistage control devices for power driven vehicles including a plurality of steam engines
IPC: B61C17/12
Filed: 1938-10-06
Abstract: 519,891. Steam engine valve gears. SCHWEIZERISCHE LOKOMOTIV-UND 'MASCHINENFABRIK. Oct. 6, 1938, No. 28965. Convention date, Oct. 7, 1937. [Class 122 (ii)] [Also in Group XXXI] In vehicles of the kind propelled by a plurality of steam engines, the valve gears of all the engines are adjusted in successive stages to various cut-offs by a single control member in such a manner that as the control member is advanced in steps the valve gears are alternately set (1) to the same cut-offs for all engines and (2) to cut-off differing in phase. Thus the total power output of all the engines can be graduated in a larger number of stages than that provided by the number of cut-off stages. In the construction shown in Figs. 1 and 2 the inlet valves 1, 2 of two steam engines are operated by slidable cam shafts 3 driven from the engine through gears 3a and having cams with three stages O, I, II acting on rollers 4 on the valve stems. The cam shafts are slid, to bring the various cam stages into use, by means of rollers 13, 13a acting through fluid-pressure servomotors 8, 6 these rollers being engaged by slidable stepped cams 14, 14a controlled by a hand lever 15. In the position shown in Fig. 1, the rollers 13, 13a are both on the step I of the cams 14, 14a and both valves 1 have the same cut-off, but the cams 14, 14a differ in phase, by the distance a equal to half the length 2a of a step on each cam. Thus, when the lever 15 is moved to the position shown in Fig. 2, the roller 13a is still on step I but roller 13 is on step II and valve 1 has a different cut-off to valve 2. The engines may be arranged in groups of one or more, there being as many gradations to each cut-off stage as there are groups. The cams 14, 14a may be slid by screw-and-nut gear 17, Fig. 3, controlled by a single hand-wheel and bevel gears 18, or they may be replaced by rotary cams. The engine cam gear 3, 3a may be that described in Specification 245,413, [Class 122 (ii)]

In addition to steadying the flow of combustible mixture, the device improves the vaporization of the fuel and the large passage 4 prevents blockage by the formation of ice.
Patent GB-698925-A (GB)
Title: Improvements in air humidifying systems and apparatus
IPC: F24F6/12
Filed: 1951-12-12
Abstract: 698,925. Humidifying air. PARKS-CRAMER CO. Dec. 12, 1951 [July 21, 1951], No. 29107/51. Class 55(ii) [Also in Group XXTX] In a humidifying system comprising atomizers supplied with air and water under pressure, the water pressure being produced by the air pressure which is regulated to control the humidity, supplementary means acting during a predetermined pressure range causes the pressure in the water vessel supplying the atomizers to vary at a faster rate than that in the air conduit so as to effect a greater variation in the evaporative output of the atomizers than is produced by the humidity regulator. In the form shown in which the air pressure producing the water pressure is maintained throughout a predetermined range less than the air pressure at the atomizers by an amount changing oppositely to the changes in such air pressure, a compressed air conduit 3 feeding atomizers 2 leads also to a water pressurizer 5 having a water inlet pipe 6, float valve 7, waste pipe 8, and an outlet pipe 4 leading to the atomizers. Connected to the compressed air inlet branch by a T section 19 a differential pressure governor is fitted comprising an exhaust port 23 the passage to which is increased as the air pressure falls so as to increase the difference between air and water pressure at the atomizers as the air pressure falls in dependence on a humidity-affected regulator 9. This may be as described in Specification 698,916, [Group XXIX]. A spring-loaded diaphragm 17 in a casing 14 depresses a ported tube 25 against a spring 27 by an amount dependent on the pressure of air which passes from conduit 3 through a restriction 31 and an opening 20 into the space below the diaphragm. As pressure falls ports 29 in the lower portion of the tube are uncovered and allow air to escape through the exhaust port. A diaphragm spring adjusting screw 22 enables the pressure point at which the valve starts to open to be selected: e.g. with an air pressure of 10 lb. the governor may be so adjusted that the reduced water pressure provides a minimum output for continuous spraying. In a modification the conduit restriction is disposed beyond the governor connection, the valve's responsiveness to pressure changes being increased. In this form the valve tube opens at the bottom into a space communicating with the conduit on the pressurizer side of the restriction and is closed at its upper part so that the space under the diaphragm is not connected to the exhaust passage. In an example employing a source of compressed air of 30 lb. pressure and with a water pressure 1.3 1b. less due to the level in the pressurizer being 3 ft. below that of the atomizers, the governor is set to increase the pressure difference to 2.1 lb. when the air pressure falls below 20 lb. and reaches the minimum of 10 1b. below which the atomizers are shut off entirely, the output at this level being reduced to 15 lb. instead of 5.5 lb.

Abstract: 1,057,621. Vehicle suspensions. G. FRESIA. July 24, 1963, No. 29392/63. Heading B7D. In a motor vehicle supported at least partially upon a pair of adjacent axles, one axle is mounted by mechanical spring means and the other by pneumatic spring means to which air under pressure is supplied through a valve con, trolled in dependence upon change of ride height of the mechanical suspension. The pneumatic suspension may be controlled by a single valve, or may comprise a spring at each end of the axle, each of which is separately controlled by its own valve. Lateral and longitudinal stability are given to the air sprung axle by a transverse bar and a triangular frame, respectively, disposed between the axle and the vehicle. The control valve comprises an air inlet port 38, a port 39 connected to the spring and a discharge port 40. A piston 25 is slidable within the cylindrical valve casing 20 being guided by a stem 25<SP>1</SP> and upwardly urged by a spring 27. A seal 24 is retained against the piston 25 by a collar 23 and spring 34 and apertures through the piston 25 connecting the space above the piston with the discharge port 40 may be closed by a valve 32 integral with a valve 33 downwardly urged by a spring 21. The spring 27 bears against a member 28 which is movable axially to an upper position in which the valve 32 isolates the discharge aperture 40 and the spring port 39 is connected to the inlet port 38 through the space C, or to a lower position wherein inlet port 38 is isolated and the spring port 39 is connected to discharge aperture 40. Axial movement of the member 28 is produced by relative movement of a pair of rotary cams 37, 36 attached, respectively, to the member 28 and a bracket 29. A lever 43 is pivotally mounted upon a spigot 45 integral with a block 46<SP>1</SP> to which are keyed a pair of levers 47.
