Patent GB-317301-A (GB)
Title: Directional aerials for transmission and reception of electromagnetic (wireless) waves
IPC: H01Q21/06
Filed: 1928-02-13
Abstract: 317,301. Williams, W. E. Feb. 13, 1928. Directive signalling.-A directional effect is secured by arraying a series of aerials so as to function in accordance with the principle of Michelson's optical echelon grating. Two or more aerial units each having directional characteristics are displaced laterally with respect to the direction of wave propagation, and are energized either at the same phase, or with a constant phase-difference, by oscillations having the same amplitude or with amplitudes varying in a definite manner. The displacement AQ, Fig. 1, is of the order of one wavelength divided by sin a where a is the angle between the principal diffracturs maximum AN of the unit AB and its first minimum AP. They are also separated longitudinally by a distance QC which may be a fraction or a multiple of a wavelength. The aerial units may each consist of arrays of rod oscillators extending in the vertical, horizontal, or any other direction. In general the separation QC of the aerial units may be of the order of one quarter wavelength, and they may be energized with oscillations de-phased by any angle of 90‹ or any odd multiple of 90‹. The main direction of unilateral transmissions can be reversed by reversing the sign of the phase-difference. As shown in Fig. 1, AB, CD, and EF represent three similar directional aerials, with or without reflector curtains or grids, arranged in echelon. If the phasedifference of the exciting currents of successive aerial units is an odd multiple of 90‹, back radiation is cancelled out, though each individual unit may radiate in either the forward or reverse directions. Where the total retardation, involving both path and phase differences, between the waves from successive aerial units, does not exceed one wavelength, each unit may be displaced, for example from CD to C<1>D<1>, when CC' is not greater than one wavelength, to give a still narrower beam. When the total retardation amounts to one or more wavelengths a variation in the direction of emission occurs with change in the frequency of the working wavelength. If the retardation is zero the direction of propagation is independent of frequency. Fig. 4 shows an alternative arrangement of aerial units AB, CD in which the displacement is BE and the separation ED. The units AB and CD are joined through inductances L. In Fig. 6 the unit ABMK is combined with the unit DCMN in echelon as before. Energy is fed to the aerials at high potential and low amperage to prevent radiation. Alternatively the feed-wires are supplied with current 180‹ out of phase, the wires being so spaced apart that the loss due to condenser action plus the loss due to radiation is at a minimum.

Title: Improvements in steering arrangements for automobiles
IPC: B62D7/14
Filed: 1937-02-15
Abstract: 489,445. Motor-vehicle steering-gear. AUTO UNION AKT.-GES. Feb. 15, 1937, No. 4573. Convention date, Feb. 14, 1936. [Class 79 (v)] In a vehicle in which the front wheels are always steered and the rear wheels can either be steered or locked in the straight position by means of a clutch which is movable only when all the wheels are in the straight-ahead position, the clutch is operated through a resilient rod or link which can lengthen or shorten if the driver's control is moved when the wheels are not in the straight-ahead position. In the construction shown applied to a vehicle having all four wheels driven through Cardan shafts m<1>, the steering arms t<a> of the wheels are operated by divided track rods tl ... t4 connected to levers s<1>, s<3> pivoted on the frame at r. The steering gear o is connected by a link q<1> to the front lever s<1> and by a link q<2> to an arm u<1> on a shaft v adapted to control the rear lever s<3>. A clutch sleeve w<1>, loose on the shaft v, is connected by an arm u<2> and link q<3> to the rear lever and can be slid to engage either a clutch collar x on the shaft v if the rear wheels are to be steered, or a clutch collar y fixed to the chassis frame if the rear wheel stub axles are to be locked. The clutch sleeve w<1> is operated by the driver by means of a hand lever j through a link e and a resilient telescopic rod g<1>, g<2> connected to a double pawl l pivoted on an arm h fixed to a shaft i carrying the clutch fork k. Thus, although the clutch teeth cannot engage except when the wheels are straight-ahead the hand lever j can be moved at any time and the rod g<1>, g<2> will be stressed to operate the clutch sleeve as soon as the wheels have been brought to the straight position. The hand lever j is locked in either of its positions by means of a catch b<1>. The double pawl l co-operates with a fixed sector l<1> to lock the clutch against accidental movement. The rod g<1>, g<2> is shown provided with springs f<1>, f<2>; rubber cushions may be used instead. The invention may be applied to vehicles having more than four wheels, the wheels being arranged in two sets of forward and rear steering wheels,
