Title: Improvements in or relating to refracting media
IPC: H01P1/20
Filed: 1951-06-22
Abstract: 706,716. Impedance networks. WESTERN ELECTRIC CO., Inc. June 22, 1951 [June 23, 1950], No. 14887/51. Class 40 (8). [Also in Group XL(c)] Devices for changing the velocity of propagation of radiant energy waves comprise a plurality of cavity elements having a characteristic impedance different from a containing medium through which the waves pass. The devices may comprise guides for electromagnetic energy, radio lenses and refractors (see Group XL(c)), and also equivalent devices for compressional waves. Preferably they are constructed to have the same impedance as the adjoining medium not containing cavity elements. The elements themselves may be channel-shaped, U-shaped or V-shaped and should have depths materially less than a quarter of the working wavelength. For compressional waves the elements must be sufficiently rigid to reflect incident waves whilst in the case of electromagnetic waves the elements require to be of conductive material. In a waveguide embodiment of the invention for the transmission of radio waves one wall of the guide is provided with a series of cavities 29 whilst a series of partial barrier plates 30 are secured to the opposite wall. The cavities 29 behave effectively as series inductances and the plates 29 as shunt capacitances so that the device may be regarded as equivalent to the circuit shown. By a suitable choice of constants it is possible to match the impedance of the device to that of other sections of guide not containing cavities or plates. The velocity of propagation in that part of the guide containing the elements 29 and 30 will, however, be reduced. The cavities need not be formed in the wall of the guide but may be supported inside as at 34 by embedding them in a suitable dielectric material 35, such as polystyrene foam, as shown in Fig. 10. Specifications 664,672 and 664,673, [both in Group XL(c)], are referred to.

Title: Improvements in or relating to aeroplanes
IPC: B64C9/32
Filed: 1940-10-07
Abstract: 544,357. Controlling aircraft. GOMME, E. D. Oct. 7, 1940, Nos. 14980/40 and 5505/41. Class 4] In an aeroplane, preferably of the kind in which the tail is lowered during landing, having means for destroying lift, means are provided for automatically bringing the lift destroying means into operation on first contact of the undercarriage with the surface on which the machine is landing. Spoiler flaps in the wings may be used which also provide a measure of drag; further drag-producing devices such as flaps may be utilized. The tail down movement of the tail plane required when the latter are used causes a third source of drag to be introduced all of which aid in making a stable landing in addition to the avoidance of "float" effected by the spoilers. The additional dragproducing devices may also be arranged to be brought into operation automatically upon the machine first making contact with the ground. In the means described for effecting the automatic operation of the spoilers a spoiler flap 1 being used in each wing, the flap is moved to the open position by a tension spring 14, when the flap is released from its closed position, by the operation of a trip mechanism, a part of which is connected to the movable core 26, Fig. 3, of a solenoid 27 the coil of which is in circuit with two switches 28, 29 each of which is automatically closed consecutively when the ordinary flaps are in their most downward position for landing and by the movement of the undercarriage on first contact with the ground respectively. The spoiler flap is carried by an arm 4 pivotally mounted about an axis 2 and is held in its inoperative position by the engagement of a pin 7 thereon with a notch 8 in the upright arm of a bell crank lever 10 which is urged downwardly by a spring 13. The lever 10 is held against the action of the latter by the engagement of a trip lever 23 with a pin 20 on the longer arm of another bell crank lever 15 connected to the first by a toggle link 19. The longer arm of the trip lever 23 is pivotally connected to the core of the solenoid 27 and when the latter is energised on landing of the machine, the trip lever 23 is moved and the toggle system collapses thus causing the spoiler flap to be released. Means are provided whereby the spoilers.are prevented from coming into operation when the machine is "taking off".

Abstract: 626,130. Detecting faults. ETABLISSE. MENTS MERLIN & GERIN. May 20, 1946, No. 15156. Convention date, Sept. 14, 1943. [Class 37] In order to test high-power D.C. switches without a high-power D.C. generator, there is employed an H.T. alternator rotated at reduced speed or otherwise arranged so that a halfwave thereof is greater than the opening-time of the switch. In a simple form (Fig. 1, not shown), the switch 5 is connected to the source 1 over a switch 4 synchronized with the source, and synchronizing means then produces opening of 5 at a suitable point in the A:C. wave, as illustrated by a curve (Fig. 2, not shown), the adjustment of time of operation &c. being such that the instantaneous voltage across the switch at moment of are-extinction is that of the corresponding D.C. generator. Tests derived from D.C. sources can be still more closely approximated to by adding a further switch 12 in series with, and operated synchronously with, that 5. Their common point is connected to one pole of a D.C. source 14 of voltage of normal switch rating. While 5, 12 are closed, this source yields negligible current, and substantially the same current traverses both switches, but when they both open, the rated voltage of the switch is supplied to its terminals by the source 14. Synchronizing means for 4, 5 are described.
