Title: Damper for use in motor vehicle suspensions
Inventor: RICHARDSON RAYMOND MANSFIELD
IPC: F16F9/50
Filed: 1970-01-06
Abstract: 1298921 Frequency sensitive dampers FORD MOTOR CO Ltd 6 Jan 1970 550/70 Heading F2S Flow of fluid through a passage 12 in a control member (30, Fig. 4, not shown) on movement of an input member 19, is restricted by a valve member 22 connected to the input member through resilient means 24. Movement of the valve member 22 relative to the control member in either direction away from an intermediate position increases the flow restriction afforded. The valve member movement is itself damped. The control member is fixed in use to a vehicle body and the input member is fixed to the axle. The rate of the spring 24 and the damping of the valve member 22 are selected such that movement of the input member relative to the control member at a frequency above about five Hz produces a response at the valve member insufficient to alter its effect on fluid flow through the passage 12, whereas movement at a frequency below two Hz produces movement of the valve member to increase its damping effect (a land 25 or 26 on the valve member obstructing the passage 12). Fig. 4 (not shown) depicts a practical construction of the damper. The valve member (45) is slidably housed in a valve cylinder (33) fixed relative to the control member (30) and movement of the valve member relative to the control member is damped by the provision of a port (58) in the wall of the cylinder. The valve member is connected to the input member (36) through a spring (51) and lever (54, 55, 37) linkage. The passage 12 is replaced by jounce and rebound passages (40, 41) having ports in a valve body (44) fixed in the valve cylinder and surrounding the valve member. Instead of being lever-type, the damper may be telescopic.

Abstract: 1,002,553. Aircraft navigation instruments. SPERRY RAND CORPORATION. Jan. 7, 1963 [Jan. 8, 1962], No.646/63. Heading B7W. An aircraft instrument comprises a cathoderay tube, and means responsive to glide path and localizer beam receivers to position on the tube traced lines representing the threshold and centre-line of the runway. The display of Fig. 1 is produced on a cathode-ray tube (not shown) and is viewed by a pilot by means of reflection in a transparent surface so that the display image appears at infinity superimposed on the external scene. The elements of the display are a horizon line depressed from the centre O of the display by a distance proportional to #, the angle of pitch, and a horizontal line and inclined line representing respectively a runway threshold and runway centreline, these lines intersecting at a point T representing a radio beacon on the runway threshold. The whole display is rotated about point O by an angle #, the angle of roll. The positions of the horizon and runway lines are so controlled that they appear superimposed on the real horizon and real runway, from a given observation point in the aircraft, if external visibility is good enough. Schematic circuits for generating the lines on the cathode-ray tube are given, Figs. 2a, 2b, and 3 (not shown), which receive input signals from devices responsive to pitch, roll, heading, altitude, airspeed, and from glide path and localizer beam receivers, and into which are set manually the known glide path angle, runway width, runway heading, and cross-wind speed. In addition, a further vertical line may be produced at the vanishing point P of the runway centre line, to show heading error. Further information may be projected to overlie the external scene, for example heading, engine speed, airspeed or airspeed error, or flight director commands produced as in Specification 1,002,552.
