Title: Infrared radiation detector
IPC: G01S3/789
Filed: 1965-03-15
Abstract: 1,071,121. Infra-red direction finders; transistor pulse circuits. HUGHES AIRCRAFT CO. March 15, 1965 [June 25, 1964], No. 10796/65. Headings H3T and H4D. Relates to an infra-red direction finder comprising an intersecting pair of detector arms, a nutating optical system selectively scanning the individual arms of a pair with an image of received radiation to generate a pulse each time an arm is scanned, and means connected to the optical system for generating an A.C. reference signal having a period corresponding to that of the nutation cycle. In a tracking system utilizing such a direction finder background radiation noise can be reduced by reducing the optical aperture but a radiation source manoeuvering violently cannot then be tracked; according to the invention first and second gate means are each connected to receive the pulses generated by corresponding detector arms, each gate means including a circuit selectively biased by the A.C. reference signal for transmitting pulses during a portion of the nutation cycle only when usable information is anticipated. In the embodiment the nutation is by a rotatable sleeve housing a tilted lens and the crossed array (17, Fig. 3) of lead selenide detectors (18 ... 21) afford " azimuth " and " elevation " pulses which are transmitted by respective gates (31, 32) controlled by quadrature reference signals to blank unwanted portions from the field of view of the array. The azimuth-arm output is amplified in a transistor circuit comprising an impedance matching emitter-follower (44, Fig. 6) directly connected to the base of an amplifier stage (45) incorporating adjustable negative feedback and followed by an impedance matching emitter-follower (51); a similar circuit is provided for the elevation channel. Transistor gating circuits.-The pulses from the azimuth amplifier are fed to the collectors of complementary transistors in a gating circuit, a reference A.C. signal voltage being applied (81, Fig. 7) for base biasing. A pair of diodes (66, 67) transmit only positive or negative pulses respectively and the circuit arrangement is such that when the reference signal is positive, only positive pulses at the input are passed to the output (71) and vice-versa.

Abstract: 857,869. Controlling height of road vehicles. ENGINEERING RESEARCH & APPLICATION Ltd. April 1, 1959 [April 3, 1958], No. 10811/58. Class 108(2). Restriction orifices are provided in the conduits 28, 32 leading from level control valves 25 to air springs 10, 11. The pressure of the reservoir 20 of the suspension system is maintained at twice the pressure in the springs 10, 11 (the pressure in which is twice atmospheric pressure). A compressor 15 driven by engine 17 feeds the reservoir via a filter 19, there being a relief valve 22. The valve 25 has a spring loaded plunger 52 which is acted on by pressure in the line 23 leading from the reservoir. Thus the plunger 52 is urged into engagement with an abutment 66 rigid with a torsion bar 41 interconnecting the two wheel suspensions. When the head 88 (Fig. 6) of the plunger 52 is permitted by the abutment 66 to be driven below a port 98, air is permitted to displace pistons 90, 91, and permit flow through connections 96, 97, to the air springs 10, 11. When vehicle is at its normal level, the head 88 closes the port 98 and flow from the reservoir, and flow between the two springs 10, 11, is cut off. When the head 88 is in the position shown (Fig. 6), the springs 10, 11 are connected by the port 98 with atmosphere. Equalisation of pressure between the springs 10, 11, is permitted when the vehicle is level laterally by the action of a valve 50 interposed in a by-pass connection 54, 55 between the springs 10, 11, and actuated by an element 69 rigid with the torsion bar 41. A similar system is described in respect of a six-wheeled vehicle (Fig. 8, not shown).
