Title: Improvements in motor vehicle lighting, with use of polarized light
IPC: F21S8/10
Filed: 1952-03-31
Abstract: 702,106. Vehicle lighting systems. KASEMANN,E. March 31. 1952 [March 30, 1951 ; April 9, 1951] No. 8138/52. Class 75 (4) A motor vehicle lighting system comprises a first system producing unpolarized light and a second system separated optically and/or spatially from the first system for producing polarized light having the distribution of a dipped light, switch means being provided to change over from one system to the other. Each system, consists of one or two headlamps and the electrical consumption of the bulbs of the second system is at least equal to the consumption of the first system. In the vehicle shown in Fig. 2 two headlamps 1, 2 provide unpolarized beams directed parallel to the road. Two additional headlamps 7 are fitted with polarizers and the polarized light is directed downwardly on to the road. The bulbs of the polarized headlamps 7 have an electrical consumption at least 30 per cent. higher than that of the bulbs of the unpolarized headlamps 1, 2 and their filaments operate at higher temperatures. The unpolarized headlamps have additional bulbs 5, 6 of low power energised with the polarized headlamps and serving as side indicating lamps ; the light intensity of these bulbs approximates to the intensity of the polarized light from the headlamps 7 as seen through an analyser. The driver of the vehicle is provided with a polarizing half-lens pair of spectacles or alternatively an analyser disc 10 may be mounted on the windscreen and be movable by a lever 18 in and out of the driver's field of vision. The movement of the screen actuates a switch 12 for switching from one lighting system to the other.

Filed: 1924-04-01
Abstract: 223,818. Mabbutt, A. W. April 1, 1924. Switches, without quick-action; switches, locking and unlocking; handles. - A key-operated two-position switch for controlling the windings of an induction coil is mounted within the coil casing and arranged in one position to complete the primary circuit and in the other short-circuit the secondary winding. The induction coil comprises a core 12 with primary and secondary windings 13, 14 contained within a casing 10 of insulating material. The front portion 17 of the casing 10 has an aperture 18 for housing the switch and its operating mechanism. The switch is operated by a rotary barrel cock 35 which is screwed into a polygonal insulating sleeve 25 having a flange 26 seated in the base of the recess 18. Attached to and insulated from the inner end of the key-operated barrel 36 is a contactmember 38 moving in a sector shaped recess. Projecting into this recess are contacts 30, 31 connected to the primary winding by spirallywound leads 28 embedded in insulating material 30<a> between the sleeve 25 and the walls of the recess 18. Consequently unauthorized attempts to tamper with the lock cause breakage of the primary winding. The contacts 30, 31 are bridged by the member 38 when in its vertical position thus completing the primary circuit, and when the contact is turned over to the horizontal position (Fig. 4) by means of the removable key 40 contacts 60, 61 connected to the ends of the secondary winding are bridged, so that the secondary is short-circuited, the primary circuit being opened.

Abstract: 946,591. Producing azimuth markers in radar displays. MARCONI INTERNATIONAL MARINE CO. Ltd. Nov. 1, 1961 [March 9, 1961], No. 8662/61. Heading H4D. In a radar system, comprising means for producing azimuth markers on a P.P.I. display tube D.T. (Fig. 1), rotor R of resolver 3, rotating with the aerial 1, induces the deflection waveform shown into a three-phase stator S feeding the display tube deflection coils D1, D2, D3 and the stator winding S<SP>1</SP>1, S<SP>1</SP>2, S<SP>1</SP>3 of a second resolver 4, having a rotor carrying two windings R<SP>1</SP>S and R<SP>1</SP>C in quadrature and forming two oscillatory circuits with capacitors C1 and C2. The flyback edges FB of the induced waveform shock the two oscillatory circuits into a series of damped oscillations with the initial pulses thereof having a sinusoidal envelope, due to the rotation of the rotor R, differing in the two circuits by 90 degrees, Fig. 2. The oscillations from windings R<SP>1</SP>S and R<SP>1</SP>C are detected respectively by valves V1 and V2, diodes D1 and D4 allowing only the negative pulses to pass to the grids, whilst diode D3 is negatively biased so as to allow only those negative pulses from winding R<SP>1</SP>C having a maximum amplitude greater than that of the largest second pulse therein to pass to valve V2, the resulting waveforms applied to the grids of V1 and V2 being as shown shaded in Figs. 2a and 2b respectively. The anodes of V1 and V2 are connected to the two control grids of valve V3, the arrangement being such that V3 only conducts during the overlapping period # (Fig. 2) once in every rotation of the aerial 1. Pulses so produced by V3, trigger flip-flop FF to produce square pulses for differentiation by circuit D.C. and application therethrough to the display tube DT to produce the required azimuth marker which may take the form of a " bright up " single or double trace on a blacked off sector. The angular position of the azimuth marker is controlled by the position of the rotor of resolver 4, which in the case of ship-borne radar may be controlled by the ship's compass to give a " north up " indication. In an alternative embodiment, a three-phase rotor may be used in the second resolver 4 and only two of the windings used to form the oscillatory circuits. An alternating type of coincidence detector is described, Fig. 4 (not shown), comprising two forwardly biased diodes connected with their cathodes each to the anodes of valves V1 and V2, and with their anodes to the cathode of a. reversibly biased output diode.

Abstract: 1,178,003. Automatic voltage control. INTERNATIONAL STANDARD ELECTRIC CORP. Feb.24, 1967 [Feb. 28, 1966], No. 8968/67. Heading G3R. [Also in Division H3] A magnetic amplifier or regulator is combined with a transformer to provide a regulated output voltage to a load. In the arrangement of Fig. 1 A. C. from source 1 is fed to transformer winding W1 wound in common on saturable cores 2, 3 and by transformer action to winding W2 wound as shown and coupled to load RL via full wave rectifier CR3, CR4 and low pass filter C, L. In addition to the transformer action primary windings W3A, W3B windings W1 and secondary windings W4A, W4B coupled to the load through diode CR1 operate as a transductor. Thus when a control signal E  s  of given magnitude is applied to control windings W3A, W3B output pulses are generated across windings W4A, W4B, Fig. 2 (not shown) which are added to the output of the full wave rectifier by means of diodes CR1, CR2. If the magnitude of the control signal E s  decreases the duration of the pulses across windings W4A, W4B are of shorter duration and hence the average D.C. voltage supplied to the load decreases. The apparatus thus operates as a variable voltage supply, variation in output voltage being obtained by varying the magnitude of the control signal E s . The circuit of Fig. 1 may be modified to operate as a voltage regulated supply, Fig. 3, by developing an error voltage E e  as shown and applying it to windings W3A, W3B instead of the control signal of Fig. 1. If the voltage across load R L  increases the error voltage he decreases causing the duration of the pulses added to the output of the full wave rectifier CR3-CR6 to decrease and thus decrease the average voltage supplied to the load. Figs. 5, 6 (not shown) illustrate how the arrangement of Fig. 1 may be applied to a three phase system.
