Abstract: 1516500 Adjusting vehicle headlamps LUCAS ELECTRICAL Ltd 29 Aug 1975 [26 Sept 1974] 41825/74 Heading F4R In a system for tilting the headlamps of a motor vehicle to maintain the direction of light beams therefrom independent of changes in vehicle body attitude, first and second elements 18, 20 are movable in response to changes in the body attitude relative to the front and rear wheels respectively and are connected to spring members 16, 17 secured to a pivotable shaft 14 connected with the headlamps so as to pull in opposition. The elements 18, 20 are, as shown, cables which, because of an outer sheath, change in effective length if the front or rear of the vehicle dips to change the tension in one or other of the springs 16, 17. A new equilibrium position of the pivotable shaft results in tilting of the headlamps in response to the change in body attitude. If both front and rear body portions are loaded equally, the tension in the springs 16, 17 is still balanced and no rotation of the shaft results.

In order to prevent jamming of a pulse radar the transmitted signal comprises recurrent groups of carrier-wave pulses, the pulses in each group being spaced in time according to a predetermined code and the phase of the carrier-wave being varied in time in accordance with a predetermined code, and the receiver includes a decoding circuit comprising means for delaying at least one portion of the received carrier-wave with respect to another by a time interval dependent on the spacing between the transmitted pulses and means for shifting the phase of the said one portion of the carrier - wave with respect to the other. As described, each pulse group comprises three pulses 1, 2, 3, Fig. 1. The time intervals # 1 , # 2  between pulses 1, 2 and 2, 3 are different, both # 1  and # 2  are integral multiples of the RF period and the RF phase of pulse 1 is opposite to that of pulses 2 and 3 as indicated by the hatching on the pulse 1. At the receiver the RF or IF echo pulses are applied to a decoder, Fig. 3, having input and output terminals 24, 30 and comprising two delay devices 25, 27 having delay times # 2  and # 1  respectively and a phase changer 29 which shifts the carrier phase by 180 degrees. Thus, each pulse reaches the output terminal 30 (1) directly, (2) with a delay # 2 , and (3) with a delay # 1  and # 2 , and a 180 degree phase shift. The resultant three components of each of the pulses 1, 2 and 3 are shown in Fig. 4 (a), (b) and (c) respectively, and it is seen that the third, second and first components of pulses 1, 2 and 3 respectively, combine to give a large amplitude pulse 34, Fig. 4 (d), which may be separated from the other components by an amplitude discriminator. In a superheterodyne receiver, Fig. 2 (not shown), the CW RF input to the transmitter modulator is obtained by heterodyning outputs from the local oscillator and an IF oscillator and selecting one sideband.
