Title: Improvements in or relating to helicopters
IPC: B64C27/54
Filed: 1943-03-29
Abstract: 567,756. Helicopters. MILLER, W. L. March 29, 1943, No. 5006. [Class 4] A helicopter is provided with means whereby the vanes may be oscillated about an axis transverse to their length as they rotate to produce a thrust component for effecting horizontal travel of the machine. Means for effecting a uniform variation of the pitch of the vanes and for automatically effecting a cyclic variation of the pitch may also be provided. The vanes 1, 3 are driven by the frictional or positive engagement of pneumatic-tyre wheels 21 with a rotatable circular track 19 supported by rollers 20 on a base 14 and secured to columns 16, 18 to which the vanes are pivoted at 15, the wheels being coupled to motors 23. For varying the pitch of the vanes, they are connected by links 25 to members 27 slidable on the columns 16, 18 and secured to a circular double track 29, 29a engaged by rollers 34 arranged to be moved vertically by hydraulic cylinders 42, 43 supplied by a manuallyoperated valve. The vanes are coupled by links 5, 7 to a rotatable disc 9 mounted by a ball-joint in a fixed support 11, 13 so that it may be inclined by a control column 46 to cause the vanes to oscillate about the pivots 15 as the vanes rotate and thus to produce a horizontal thrust component dependent upon the direction of inclination of the disc. Equalization of the lift at the two sides of the machine when the machine is heading into a wind is maintained, since, as the several cylinders 42, 43 are interconnected, upward movement of the pistons at one side of the machine to reduce the pitch of the vanes that are moving into the wind is permitted with consequent downward movement of the pistons on the other side of the machine to increase the pitch of the vanes on that side, the track 29, 29a assuming an inclined position. Manual means may be provided for effecting the inclination of the track for equalizing the lift. The machine may be provided with a small propeller to assist horizontal travel and the helicopter device may be incorporated in an aeroplane. The control valve means for cylinders 42, 43 may be of the follow-up kind.

Title: Improvements in or relating to air screws
IPC: B64C11/30
Filed: 1942-04-17
Abstract: 562,678. Screw propellers. STEVENS, A. H. (Canadian Car & Foundry Co., Ltd.). April 17, 1942, No. 5131. [Class 114] In a variable-pitch propeller, speed responsive means carried by the hub are connected to the blade adjusting means by mechanism which causes the pitch to vary inversely to the speed of rotation in the upper part of the speed range and directly with the speed in the lower part of the speed range, the mechanism being brought into operation at maximum speed and put out of operation at minimum speed. The blade socket 14 has secured thereto a cam block 40 having a cam groove of triangular shape, the base of the triangle extending longitudinally of the blade socket. The bottom of the groove is formed with ratchet like projections having ramps 44 and abrupt shoulders 45a, 45b, 45c, which permit movement of the cam follower 34 round the groove only in the direction of the arrows in Fig. 7. The cam follower is carried by a block 30 mounted to slide in a guide 31 in the hub socket 12 and the block is connected by a rod 50 to a rack 49 geared to a spring drum which urges the block 30 so that the follower 34 occupies the corner a of the cam groove, this position corresponding to minimum pitch. As engine speed increases from minimum to maximum during take-off the follower 34 under the action of centrifugal force on the block 30, moves to the corner b without change of pitch. Upon reduction of engine speed to cruising speed, the block 30 is partly withdrawn by the spring drum so that the follower 34 moves to the corner c, turning the cam 40 and thus moving the blade to maximum pitch. At this position the engine speed may be again increased without change of pitch as the shoulder 45c prevents outward movement of the block 30. During landing of the aircraft, the follower moves from corner c to corner a restoring the pitch to minimum. In a modification the cam 40 is arranged on the inside of the hub socket, the block 30 being slidably guided on the blade root. The blade root may be secured in a socket 13 which may be initially adjusted angularly in the socket 14 by the insertion of a pin 18, Fig. 5, in a pair of half circular holes in the parts 13, 14 the holes being of different pitch in the two parts to allow of fine adjustment. Balance weights for the blades are secured to arms 25 extending from the roots of the blades through slots to the front of the boss. The blade is secured to the socket 13 by a wire 17 wound helically in a groove in the blade socket and screwed into a corresponding groove in the socket 13 as described and claimed in the Specification 562,711.

Abstract: 608,388. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 21, 1946, Nos. 5484 and 5485. Convention dates, Feb. 21, 1945. [Class 40 (iv)] In a marker selection control system of the type in which simultaneous hunting takes place by several selectors over the same marking multiple, and each marking device is provided with an individual current source; after a selection has been made, a further test is performed to check that the selection conforms with the position of the marker, and if the latter test fails, owing to a cross-connection having occurred, hunting is resumed. As shown in Fig. 2, a selector is driven by its electromagnet R in search of the group marked by MW, to the first contact of which group relay T operates in series with the individual current source S, followed by D which disconnects T and connects up the outlet testing relay Gt, under the control of which the selector hunts for a free outlet in the group selected. Operation of Gt brings up Sh and E, which reverses the current flow through T and reconnects it in the test circuit. If the selector is on the marked level, T re-operates and brings up the end of selection relay FS. If, however, the selector is not on the marked level, then owing to the slightly different times of operation of the sets of relays Gt, T and E of different selectors, T does not re-operate, but F comes up, disconnects wiper t and releases D to restart the search. Commoning of marking wires over the windings of the N relays is prevented by the rectifiers placed in series with the relays. In the modification of Fig. 3, the marker contacts and the group multiples in the bank of wiper t are connected to different potentials derived from the rectifiers U1, U2 ... and the check is made by a relay set A1, A2. On the operation of E after the selector has stopped, A1 comes up and connects A2 between the wipers t and MW, so that if the selection is correct and the wipers are both at the same potential, A2 remains unoperated and FS pulls up. If, however, the wipers are on different groups, A2 comes up, the subsequent operation of F releasing D to restart the search.
