Title: Improvements in and relating to means for controlling aeroplanes
IPC: B64C13/02
Filed: 1921-10-28
Abstract: 173,213. Soc. Anon. des Ateliersd'Aviation L. BrÚguet. Dec. 18, 1920, [Convention date]. Steering and balancing.-In an aeroplane control comprising a hand-wheel for controlling the lateral and longitudinal balance of the machine mounted on a support pivoted at its lower end so that the wheel can be moved laterally to occupy a position in front of either of two pilots, the elevator is controlled by longitudinal sliding movement of the support. The lateral movement is effected without rotation of the lateral control shaft, and means are provided for locking the device in either of its extreme positions. A handwheel v is journalled in a casing c integral with a tube e<1> which forms an extension of the elevator control-shaft e to which it is connected by a coupling m allowing relative rotary but not axial displacement. Consequently a fore-and-aft movement of the casing c moves the shaft e and operates the elevator. The shaft of the hand-wheel v has sprockets b connected by chains f to sprockets g splined to a tube d which effects the lateral' control. The casing c can be swung laterally to move the hand-wheel from one side of the machine to the other, the chains f rolling idly about the sprockets g during the movement. A member j rotating in a fixed part i of the frame is splined to the tube e<1> which moves with the casing c, themember j having a spring bolt h for locking it tothe frame n in one or other of its extreme positions. Rotary movement of the shaft e effects movements of the rudder for which purpose the shaft is splined to a member k rotating in a fixed part i' of the frame and connected to the rudder bar.

Title: Method of and apparatus for controlling the viscosity of liquids
IPC: F23K5/20
Filed: 1934-10-13
Abstract: 428,431. Valves. PEABODY, Ltd., 4, Clement's Inn, London.-(Peabody Engineering Corporation; 580, 5th Avenue, New York, U.S.A.) Oct. 13, 1934, No. 29371. [Class 135] The viscosity of a liquid is controlled by causing it to flow through means across which a substantially constant drop of pressure is maintained and in which the rate of flow varies with the viscosity, the variations in the flow through these means being utilized to regulate means for adjusting the temperature of the liquid. In the apparatus shown, oil supplied to oil-burning systems for example passes from the inlet 10 to a heater 9 exposed to a heating medium e.g. steam, in a casing 1. The steam supply through a pipe 2 is regulated by a diaphragm-actuated valve 3 under the control of a pilot valve 4 in a branch line 2<1>. Oil passes from the heater to a fitting 11 connected to the main outlet pipe 12 and a branch pipe 15 through which oil is led past a pressure regulating valve 20 to a device sensitive to changes in viscosity such as the coil 27 of small bore tubing the pressure difference between the ends of which is arranged to be constant. The outlet of the coil 27 is connected to a chamber 28 below the diaphragm 34 of the pilot valve control device and oil passes from this chamber past a restricted orifice, Venturi tube, or similar device 38 to the chamber 36 and thence to a return line 16. The pressure difference due to the throttle 38 acting on the diaphragm 34 tends to close the valve 4 through the abutment rod 45 and valve stem 44 against the opening action of adjustable springs 42 acting on the yoke 41. To maintain the pressure drop across the coil 27 constant, its outlet is connected by a pipe 46 with the chamber 23 below the diaphragm 21 of the valve 20. The normal pressure of the inlet of the coil 27 is the same as that in the outlet chamber 19 and is determined by adjusting the loading spring 24. This adjustment together with that of the springs 42 determines the viscosity to which the oil is regulated. A decrease in the viscosity below the predetermined value causes an increased flow through the coil 27, and hence an increase in the pressure difference across the throttle 38. This tends to shut down the valve 4, and the valve 3 moves to cut off the steam supply until the viscosity rises to the predetermined value. An increase in the viscosity above the predetermined value similarly brings about a decrease in the flow through the coil 27 and ultimately a further opening of the steam valve 3.

IPC: B60T8/18
Filed: 1964-07-20
Abstract: 1,108,185. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. 20 July, 1965 [20 July, 1964], No. 29469/64. Heading F2F. In a compressed air braking system, for a motor vehicle having air suspension, the brake cylinders are supplied under direct control of a driver's valve via a load-responsive pressure limiting valve arrangement comprising: a piston 5 which, in response to driver regulated pressure at an inlet 2, operates a dumb-bell type combined inlet/exhaust valve structure 6, 8 controlling a feed passage 21 in the piston and an exhaust passage 10, respectively, associated with delivery port 3; a second piston 13, loaded by a spring 14 against the action of delivery pressure communicated to the space above the piston by passage 12; and an intermediate variable leverage device comprising a beam 18 fulcruming on a roller assembly 19 whose position is adjustable by a spring-loaded piston 22 acted on by pressure in the air suspension acting at an inlet 27. One end of the beam is pivoted to the stem 17 of piston 5 while the other end has initial free movement in a yoke 16, connected to piston 13, until rising delivery pressure causes piston 13 to depress the yoke to engage the beam and balance the effect of piston 5, so limiting the delivery pressure at port 3 relative to the inlet pressure at port 2 in a ratio determined by the condition of the air suspension. The roller assembly 19 consists of two pairs of rollers (19a) and (19b) (Fig. 2, not shown), the former engaging tracks 20 and the latter the beam 18. The rollers are carried by a spindle 19c engaged with a piston rod 24 connected to piston 22. To prevent only weak braking being available should pressure fail in the air suspension, a valve (28) (Figs. 3 and 4, not shown) is in this event adapted to be operated by excess movement of a levelling lever (30) to control a combined inlet/exhaust structure (32), (34) whereby the underside of piston 13, normally at atmospheric pressure, is connected to an air pressure supply port (36) so that no balancing force is applied to the beam and the full pressure at inlet 2 is available at the delivery port 3.

Title: Liquid-flow meter with pistons
IPC: G01F3/18
Filed: 1946-10-03
Abstract: 629,896. Liquid meters. STOPPANI AKT.- GES. Oct. 3, 1946, Nos. 29555 and 29556. Convention dates, Oct. 5, 1945 and Sept. 28, 1946. [Class 69 (ii)] In a liquid-flow meter comprising two cylinders lying side by side with their interiors connected with each other at one end and two rotable and axially-movable pistons one in each of the cylinders, there is provided a measuring-chamber defined by the interconnected ends of the cylinders and limited by the piston ends facing the mutual connection of the cylinder interiors as well as two separate measuring-chambers in the cylinders at the other side of the pistons, control ports in the walls of the cylinders and control openings in the walls of the pistons, and means for causing oscillation of the pistons to change the mutual positions of the control ports and openings to control the inlet and outlet to and from the three measuring-chambers. Within a cylinder block 2, Fig. 1, are two parallel bores 3 and 4 each having separate measuring- chambers I, II, Fig. 5, respectively, at one end and both communicating at the other end with the third measuring-chamber III. Liquid flowing through the chambers causes reciprocating motion to be imparted to pistons Ka and Kb ; the pistons are arranged to have a mutualoperating phase-displacement of 120 degrees. Each piston Ka, Kb has a ball-and-socket joint halfway down its length which through a pivot 11 is connected with a gear-wheel 12 so that the reciprocation of each piston causes it to also experience an oscillating rotary motion and to thereby enable each piston to control ports in the lower half of the diameter of the bore and its own periphery. Both gearwheels 12 are connected with a totalizer or counter (not shown). Piston Ka embodies three ports EK1, AK1, Fig. 1, and K3, Fig. 6, whilst piston Kb has an identical arrangement of ports. Cylinder bore 3 is provided with two slots EZ1 and AZ1 which in conjunction with the piston ports EK1 and AK1 comprise the inlet and outlet to and from chamber I. Two further slots EZ3, AZ3, Fig. 5, in the cylinder bore 3, together with port K3 in the piston Ka constitute the inlet to and outlet from chamber III. Four similar slots in cylinder bore 4 and the three ports in piston Kb provide access to chambers II and III. In a modification the slots and ports in the cylinders and pistons respectively are located in both the upper and lower parts of the diameter, there being six ports in each piston and eight slots in each cylinder bore. The pivot of each piston is connected to a disc on the shaft of a bevel wheel, both of which latter are in mesh. The shaft of one bevel wheel is connected to. operate the counter. The number of ports in each piston may be reduced to two. The liquid entering the meter takes two paths, one part supplying the upper ports and the other the lower ports both streams re-uniting prior to discharge.
