Title: Improved carburettor for aviation engines
IPC: F02M69/00
Filed: 1938-04-06
Abstract: 498,974. Spray carburetters. LAURET, M. A. April 6, 1938, No. 10548. Convention date, Feb. 21. [Class 7 (iii)] In a carburetter for aviation engines, a single fuel valve regulates the fuel outflow according to the pressures of both the atmosphere and the inlet manifold and has an outline which is such that the area of passage for the fuel will vary by the same percentage when the needle is displaced by a given length, starting from any starting position. The outline is determined from the formula d= D#1-e<8x> where d is the diameter of the needle at a distance x from its end, D the diameter of the orifice into which it penetrates and s the constant variation of the area of the passage around the needle per unit length of the displacement of the needle. A fuel valve 40, Fig. 6, is supported in a seating sleeve 26 by a rocking lever 44 one end of which is pivoted to a bell-crank lever 51 connected by a link 49 to a capsule 45 exposed to the pressure at the intake of the carburetter while the other end is carried by a cam plate 62 connected through a rod 59 with a capsule 46 exposed to the pressure in the inlet manifold. The capsule 46 also controls a device for limiting the pressure in the admission manifold by operating through a lever 68, Fig. 3, pivoted at 69, a slide valve 71 controlling the flow of pressure oil to either face of a piston in a cylinder 77, Fig. 5. A cable 80, passing through the axis of a shaft 84 and along an arm 83 rigid therewith, connects the piston to the pivot of a link 88, connected to the throttle spindle, displacement of the piston actuating the throttle valve if the shaft 83 is stationary and in any case varying the leverage between that shaft and the throttle valve. The limit placed on the pressure in the manifold by the capsule 46 is adjusted manually by raising or lowering the pivot 69 of the lever 68, the pivot being mounted on links 91 which may be raised or lowered either by an eccentric pin 99 on a rotatable shaft 98 or by a similar pin on the shaft 84. The shaft 84 operates an acceleration pump having at its lower end a clack valve permitting admission of the fuel and arranged above a partition carrying the outlet valve. The proportion of fuel in the mixture may be adjusted manually by raising or lowering the valve sleeve 26 which is formed at its lower end with an enlargement 25 pressed against a shoulder 24 on a nipple 22 by a spring 28, the control handle being connected to a known device for providing starting mixture and cutting off the idling nozzle when the engine has to be stopped. In a modification, the pivot 69 is carried directly by an eccentric mounting on the shaft 84, two floats are used, and the altitude capsule 45 is immersed in the fuel, a link 48, Fig. 9, connecting it to a lever 49 having an adjustable pivot 50, the lever being pivoted at its end to the rocking lever 44 which is also linked to the shaft 85 to permit the limitation of the inlet manifold pressure to be effected without the aid of the capsule 46.

Title: Improvements relating to wind deflectors or wings for vehicles
IPC: B60J1/14
Filed: 1931-04-10
Abstract: 363,585. Vehicle w i n d s c r e e n s . ROBINSON, A. P., 600, 8th Avenue North, Seattle, Washington, U.S.A. April 10, 1931, No. 10660. Addition to 341,813. [Class 103 (ii).] In a modification of the invention of the parent Specification, in order to adapt the wind deflector for use with any type of door or body panel having a drop window, the deflector is arranged to slide from its upper operative position in which it is inclined rearwardly and outwardly to a lower inoperative position in which it lies parallel to and outside the body or door along a guide member that is supported externally of the body or door. The pivotal movement of the deflector may take place either when the latter is near the lower or upper limit of its movement, and, in the former case, provision may be made for supporting the deflector in an intermediate operative or inclined position. In the construction shown in Figs. 1 and 2, the frame 10 of the deflector 1 is pivoted by means of lugs 11 in brackets 20 mounted on a slide 2 working on a guide 3 that extends to the upper edge 90 of the window opening. A pin passing through one or each of the lugs 11 engages a cam slot 31 in the guide 3, the cam being so shaped as to swing the deflector inwardly at the desired part of its movement. A pivoted catch 4 on the slide 2, engages notches 34 on the guide 3 to retain the deflector in its upper and lower and, if desired, intermediate positions. In a modification one edge of the guide 3 is discontinued at its lower part, leaving the deflector free to swing about the other edge. In another modification, Figs. 6 and 9, the guide 3 extends upwardly only to the window sill 91, and the swinging movement of the deflector frame 10 is provided for by the sliding engagement of a flat bar 25 on the slide 2 with a corresponding flat surface 31<1> on the guide 3. Spring pins 15 on the upper edge of the deflector engaging apertures in a bracket 5 on the door frame assist in supporting the deflector when it is at the upper part of the guide 3. In a further modification, the deflector is arranged to pivot on the guide 3 at any point of its movement, and is supported in an inclined condition at the positions desired by means of a hook resting on hinge members of the door. In any of the constructions the deflector, in its lowermost position, may rest in a pocket of small or any suitable depth on the outside of the door.

Filed: 1952-04-28
Abstract: 715,542. Electric control systems. SIEMENS & HALSKE AKT.-GES. April 28, 1952 [April 27, 1951], No. 10706/52. Class 40 (1). - In a position indicating system wherein the position of the wiper B, Fig. 1, of a transmitter resistor W is indicated by a resultant field type receiver E, the latter comprises two coils S1-S2, R mounted for rotation relative to a constant magnetic field produced e.g., by a permanent magnet P-P and disposed so as to produce two mutually perpendicular fields. One receiver coil R is connected to the mid-point of the two similar component coils S1, S2 of the second coil, and the coils S1, S2 are connected to the ends of the transmitter resistor W so that they carry opposing currents. The field produced by coils S1, S2 depends on the difference of the currents in the lines L1, L2 whereas the field produced by coil R depends on the sum of these line currents. By suitably dimensioning the components the angular displacement of the receiver may be made directly proportional to the linear displacement x of the wiper B from its mid-position. By replacing the coil R by two opposing component coils R1, R2, Fig. 2, and connecting one of them in series with a resistor W1 equal to W, the rotation of the coil system is made independent of the total current flow through the receiver so that any number of receivers may be used with one transmitter without special adaption thereof to the momentary load. The resistor W1 may be constructed as a potentiometer similar to W with the negative supply pole connected to the tapping, and it is shown in the Specification that by alternately operating W and W1 from the transmitter end a rotation of 360 degrees of the receiver may be obtained, Figs. 3, 4 (not shown). Fig. 6 shows such an arrangement in which further resistors V, V1 are connected in parallel with W, W1, respectively, by arcuate conducting bars. By mounting the wipers B, B1 at right angles to each other on a common operating shaft only one of the potentiometers can be varied at a time and the components may be adjusted to produce true angular correspondence of the receiver rotor with.the transmitter. The receiver may comprise four fixed coils as in Fig. 2 co-operating with a permanent magnet rotor or as shown in Fig. 6 the four coils may be replaced by an equidistantly tapped toroidal coil.
