Title: Stabilizer for aerodynamic or ballistic flying bodies operating in electric fields
IPC: B64C23/00
Filed: 1964-03-16
Abstract: 1,064,235. Aircraft. H. VON ENGEL. March 16, 1964 [April 4, 1963], No. 11105/64. Headings B7G and B7W. [Also in Division F3] A stabilizing or control member for a flying body subjected to the action of an electrostatic field has an electrically conducting surface or surfaces forming one or more parts of a helix. In Fig. 3, for example, a stabilizer 7 is attached to a flying body 3, and is stated to diminish any tendency for an electrostatic field to divert the body from its course. The stabilizer is rotatable about the fore-and-aft axis of the body 6. Two such stabilizers may be hinged to the trailing edge of an annular wing, which may also be a ram-jet casing. Discrete parts only of the helix may be electrically conducting, these parts being embedded in a non-conductive support. Such stabilizers or control members may also provide some propulsive and lifting forces in an electrostatic field. Two such stabilizers may be attached at diametrically opposite points of the body, or two bodies may be attached one to each end of a stabilizer. A plurality of stabilizers may extend downwardly from hinge joints on the body. A kite-shaped body may have helices extending from both its upper and lower surfaces. In Fig. 10, a number of stabilizers 28 are attached to a body 27, and each terminates in a lifting aerofoil, the tip of which is adjustable for trimming or control purposes. Each stabilizer is rotatable about its axis, and the set of stabilizers may be rotatable about the body 27 to provide lift like a helicopter rotor. The flying body may itself set up an electrostatic field, by means of radio-active sheet metal, thermal ionization devices, or by the friction of a discharge nozzle on streams of gas or essential oils.

Title: Improvements in or relating to motor road vehicles
IPC: B62D61/02
Filed: 1937-04-20
Abstract: 494,013. Safety wheels and steering-mechanism for motor-cycles &c. WASLEY, T. J. J. April 20, 1937, No. 11252. [Class 136 (i)] A motor vehicle having road wheels arranged in tandem is provided with auxiliary stabilizing wheels located on both sides, means controlled by the speed of the tandem wheels to lower or retract the auxiliary wheels on to or from the road surface, and control means operated from the steering-mechanism of the vehicle for lowering or retracting the auxiliary wheels singly, the arrangement being such that when cornering the outer auxiliary wheel is lowered to cause the vehicle to lean over inwards. An auxiliary wheel 12 on each side of the vehicle is carried by an arm 8, which is pivoted at 9 to a low intermediate section 4a of the frame 4 and is connected by a link 16 to a piston rod 15, the piston of which is pressed down in its cylinder 14 by a spring and is adapted to be raised at a limiting speed of the vehicle by compressed air from a pump 17. The air pump 17 is driven from the rear road wheel 6 by a belt 18, and the supply of air to the cylinders 14 is controlled by a centrifugal governor 19 driven from the air pump by a belt 20. The pump 17 supplies air to the lower ends of the cylinders 14 through a branched pipe 21 provided with a valve 22, which is controlled by the governor 19 through a link. When the speed of the vehicle decreases to the limit of lateral stability, the operation of the valve 22 to cut off the air supply to the bottom of the cylinders 14 also opens another branched pipe 48 to admit air to the upper ends of the cylinders 14 to assist the springs in depressing the pistons. In order to prevent overturning when cornering, the outer auxiliary wheel 12 only is automatically lowered to cause the vehicle to lean over inwards, this action being effected from the steering-mechanism 30 by a drop-arm 29 having a depending pin 44 adapted to actuate either of. two bell-crank levers 32 having pin-and-slot connections with levers 36, which are pivoted at 37 and are connected by links 39 with valves in the branch pipes, whereby air is passed to the upper end of one cylinder 14 only, to lower the wheel 12 on that side. The front wheel 5 is steered through the droparm 29 and a lever 53 on a vertical spindle 53a, which passes through a frame 54 and rotates a turntable mounted on ball-bearings. The front wheel 5 is also the driving-wheel, being driven from the engine 50 through a change-speed gear 51 and a flexible shaft 52.

Title: Improvements relating to error check devices for computing typewriters
IPC: G06C21/04
Filed: 1927-05-02
Abstract: 298,096. Myers, L. C., and Royal Typewriter Co., Inc. May 2, 1927. Adding-apparatus; attachments to typewriters.-In a computing typewriter provided with a column totalizer and a grand totalizer, as in Specification 298,095, the depression of an incorrect key when entering the column total in the grand totalizer results in this key being locked against return. A lever 193 tending to rock counterclockwise under the action of a spring 242 is normally held up by a latch 192. When the grand totalizer arrives in the computing zone, however, this latch is removed and the lever rocks a bellcrank 246, Fig. 3, to slide a rock arm 248 into clutching connection with the universal plate 239 rocked by the keys, and also through a link 256 and lever 257 to slide a shaft 255 to the right to bring sectors 254 thereon into the planes of proiections 267 on the key-actuated rods 24. The arm 248 is linked by a spring to a cam 253 which, like the sectors, is fixed on shaft 255. Thus when a key is operated the plate rocks the shaft 255 and consequently the feelers 214 connected with the sectors rise into contact with the digit wheels 216. If the digit of the column totalizer wheel corresponds with the key struck the rod 24 passes freely to and fro through an opening in the sector 254. Otherwise the projection can force its way past the sector owing to the wedge shape of the projection, but its return and therefore that of the key cannot take place. By depression of a " disconnect " key 260 the whole of the sectors 254 and their shaft 255 can be displaced to the left to liberate any rod thus caught.
