Title: Improvements in aircraft navigation instruments
IPC: G01S1/02
Filed: 1945-06-08
Abstract: 611,047. Electric indicating instruments. SPERRY GYROSCOPE CO., Inc. June 8, 1945, No. 14561. Convention date, June 9, 1944. [Class 40 (i)] [Also in Groups XIX and XL (c)] An aircraft navigation instrument shows on the same dial the craft's distance from a predetermined flight path defined by radio-beam guiding means and also its distance from an independent reference such as the ground. It may consist of a cross-pointer meter M on which pointer 11 co-operates with scale 14 to show the distance of the craft from an overlapping beam or other radio glide path and movable mask 15 indicates, on the same scale 14, the altitude. In an overlapping beam-type receiver, Fig. 2, arranged to operate with beams having characteristic tone modulation, the detector 18 provides signals for the A.V.C. circuit 26 which operates both on the intermediate frequency amplifier 17 and on the audio amplifier 19 to produce a receiver gain proportional to the square of the distance from the transmitter. This renders the output across resistors 25, fed in opposition by the rectifier output of audio filters 21 and 22, substantially proportional to the linear distance of the craft from the equisignal path irrespective of the distance from the transmitter. Two independent receivers are shown in Fig. 2 co-operating with centre zero movements to indicate horizontal and vertical displacement and actuated by glide and approach path beams. The mask 15 co-operating with the vertical displacement scale is controlled by an altitude sensitive pressure capsule 31 through mechanical gearing, Fig. 6; servo mechanism, Fig. 4, or a simple D.C. electric circuit including a d'Arsonval movement, Fig. 3; (Figs. 4 and 6 not shown). A spring-loaded slip clutch, Fig. 5 (not shown), may be used to adjust the mask to the correct reading, for instance on receipt of marker beacon indications at an airport; in the electric circuit control of Fig. 3 electrical adjustment is provided by potentiometer 64 for this purpose. An index 13, representing the craft to the dial scale, is provided at the centre, or on-course, position of the meter M. This index may be attached to a gyroscope by a thin support and be free from the dial so that it will also indicate the craft's banking angle; alternatively, the index may be fixed and the dial and indicators stabilized. It is stated that the dial may be translucent and illuminated from behind with the pointers mounted either in front of or at the back of it, a pointer arm can be substituted for the mask if desired or a cathode-ray tube used to display the indications.

Filed: 1975-03-24
Abstract: 1504516 Interrogator-responder systems PLESSEY CO Ltd 24 March 1975 [2 April 1974] 14626/74 Heading H4L In an interrogator-responder system for use in vehicle detection, the direction of travel of the vehicle is assessed at the interrogator, by comparing the phase of the signal returned from the vehicle responder (this signal comprising a data signal having a frequency related to the interrogator clock frequency) with that of a reference signal derived from the interrogator clock frequency radiated to the vehicle. When the returned signal is at half the clock frequency, for one direction of travel the phase of the returned signal will either be the same or different by # from the reference, while in the other direction it will be #/2 leading or lagging. It is desirable to arrange the transponder receiver end transmitter loops in upright positions in the vehicle perpendicular to the road and also at right angles to the direction of movement. If the relationship between the returned and clock frequencies is some factor other than half, then some other phase relationship will apply.

Title: Sucker rod compensator for subsurface well pumps
IPC: F04B53/14
Filed: 1967-03-31
Abstract: 1,136,887. Reciprocating pumps. BAKER OIL TOOLS Inc. March 31, 1967 [April 29, 1966], No. 14888/67. Heading F1A. A device for maintaining a full stroke of the bucket piston of a deep well pump, Fig. 3a (not shown), by compensating for changes in the lengths of the sucker rod and tubing strings due to temperature changes and the like, comprises a cylinder member 35 secured to the sucker rod 28 and a piston 68 secured to the pump operating rod 29. During the upward stroke of the bucket, liquid in chamber 47 beneath piston 68 is pressurized, and a small quantity passes through a restriction 51 into chamber 52, and then through passages 58 and 59 into reservoir 60 closed by a free piston 61 subjected to the pressure in wall tubing A. The slight flow of liquid through restriction 51 during each upstroke causes an effective lengthening of the sucker rod string until the bucket bottoms against an abutment in the pump barrel at the end of its downward stroke. When bottoming occurs, the continued downward movement of the sucker rod string reduces the pressure in chamber 47 sufficiently to open a spring-loaded valve 71, liquid then passing from chamber 52 into chamber 47 while cylinder 35 moves downwardly relative to piston 68. The device automatically adjusts the sucker rod string length so that the bucket lightly taps the bottom of the barrel at the end of each downward stroke.
