Filed: 1938-06-13
Abstract: 498,995. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. June 13, 1938, No. 17555. Convention date, June 12, 1937. [Class 40 (v)] Two parallel frame aerials D1, D2, spaced apart to eliminate night-effect, and rotatable about a common centre A, are coupled in opposition to a receiver ED, whilst an auxiliary parallel frame H at the centre is coupled to a receiver FH. The outputs from the two receivers are applied, as shown, to the deflecting plates of a cathode-ray tube B. The resulting " bearing " trace on the screen shows only two minima, instead of four, the correct "sense" of the bearing-line being indicated, as between the two minima, by the fact that one trace moves to the right over the screen, whilst the other moves to the left. Fig. 3 shows the relative phases of the combined-frame voltage J and the auxiliary frame voltage H. The only two critical readings are at 0 and 180‹; as these voltages are in phase-opposition, they cause the directional trace to move in opposite directions and thus remove the 180‹ ambiguity.

Abstract: 436,977. Controlling - switches for lifts. WADSWORTH & SONS, Ltd., W., High Street, and DISLEY, H. J., 157, Withins Lane, both in Bolton. June 14, 1934, No. 17609. [Classes 78 (ii) and 78 (iii)] A switch for controlling a lift, for example a floor-levelling switch, in which one part of the operating mechanism is carried by the moving cage and the other part is fixed in the well, is mounted so that want of alignment of the two operating parts does not affect the operation of the switch. In the form shown the switch comprises contacts b on a pair of members a adapted to be bridged by a guided sliding member i. The members a are hung by pivoted links c, d while the member i is connected to a third pivoted link g normally urged towards the link d by a spring k. Rollers p, q operated by a fixed cam r in the well, rotate the spindles o, e to separate the links g, d to open or close the switch as the case may be. Want of alignment between the cam r and the rollers p, q is taken up by the swinging of the linkage system as a whole in the same direction, both parts a and i being affected equally without any relative movement which would tend to operate the switch. In a modified construction the link d and member a are connected rigidly so that they swing as a unit about the point e. Manually - controlled electromagnetic means holds the links g, d apart when it is desired to pass any particular floor without stopping. The multiplying effect of the levers g, d, c causes the switch to be operated with a quick " make and break " which minimizes arcing.
