Abstract: The present invention relates to vehicle bumper assemblies of the type which includes at least one profiled, preferably Ushaped beam or the like adapted to be securely mounted to the frame and/or the body of the vehicle in a manner whereby the outer contours of the bumper are located outside the vehicle body or part thereof and are active in a shock absorbing capacity. Such an envisaged assembly is provided with a number of shock absorbing insert members arranged to bear against the web of the beam structure and to extend externally of the beam profile to an extent which is at least one fourth of its total height. It is basically characterized in that the beam is provided with a plurality of stays or plates which extend transversely between the longitudinally extending limb portions of said beam and which divide the beam into pocket-like sections in which the inserts are individually mountably arranged. The inserts preferably comprise cellular blocks and consist of a number of tubes of a semi-elastic or plastic material. A protective casing surrounding the beam and the inserts has an open longitudinally extending groove arranged in its rear side. This permits the casing to be stretched when mounted in position.

Abstract: An actuator movable in a plane parallel to coordinate x and y axes is biased to a normal position by a leaf spring parallel to the x axis and flexible in the y directions. A lever parallel to the y axis has the actuator at one end, a rigid connection to the middle of the leaf spring at the other. The lever is constrained to lengthwise motion and to swinging about said connection. The leaf spring ends are confined to x direction motions. Strain sensors, secured to the leaf spring between its middle and its ends, are connected in bridge circuits that produce outputs respectively corresponding to x and y components of actuator displacement.

Abstract: In apparatus for gunnery practice by which firing towards a target comprising a reflector is simulated by laser emissions, a first radiation emission at firing is used for ranging, to ascertain a time interval following firing at which a round of a selected type of ammunition will arrive at the target. After that interval following firing, a second emission is used to obtain a fix on the target. The second emission comprises pulses encoding information about ammunition type and relation of point of impact of the simulated round to target location, to be decoded at the target and used for evaluating hit effect.

Abstract: A known quantity of X-ray-opaque tracer is injected into blood entering an organ to be examined. X-rays are passed through the organ to an imaging plane. Image records are made periodically through a cycle of the organ. Selectively delineated image areas of each record of interest are scanned to produce a signal corresponding to blackness variations across the image. The signal is so amplified as to produce an output that varies with tracer concentration across the projected area of the organ. Integrating that output for each record provides a final output representative of tracer concentration in the delineated organ portion.

Abstract: A flow meter comprises a screw turbine having its axis parallel to stream flow, to be rotated thereby. The turbine carries axially oppositely facing clutch members and is free for limited axial movement. When rotating too fast for stream flow, it moves upstream, engaging one clutch member against a cooperating fixed clutch element, and is thereby decelerated. Rotating too slowly, its downstream drift engages the other clutch member against a second cooperating clutch element which is motor driven to rotate faster than highest expectable turbine speed, for acceleration of turbine rotation.

Abstract: In a brake control system of wheeled vehicles, particularly of motor cars, an arrangement measures the vehicle speed by means of an accelerometer of simple type to produce a signal representing the speed of a braked individual wheel relative to the vehicle speed. The wheel is intermittently braked to be temporarily freerunning without slip so that the true vehicle speed is repeatedly measured by an inductive or other speed transmitter. Furthermore, the vehicle speed is continuously, though inaccurately, measured by integration of the output of an accelerometer of a simple cheap type. This integrated output is repeatedly corrected by being updated with the true vehicle speed intermittently measured by the speed transmitter when the wheel is free-running. During those periods during which the wheel is braked and may be lagging (slipping), the measured wheel speed differs from the updated speed represented by the integrated and updated accelerometer output. By comparison of these two speed values, an electrical signal representing the slip is produced and may be used for temporarily releasing the brake means of the vehicle when slip occurs or at least when the ratio of slip to speed passes a predetermined limit value. Any accelerometer output representing a negative retardation, i.e. positive acceleration, is suppressed.

Abstract: In an aircraft having an ejection seat and having a recess in its cabin defined by an overhanging wall, a collapsed bladder is arranged in the recess to provide an unobtrusive cushion for normal flight. The bladder is rapidly inflated just prior to ejection, whereupon it forcefully displaces the seat occupant''s limb to a position safe for ejection and fills the recess to prevent the airman from inserting a body member thereinto. Quick inflation expedients are disclosed, operable in an automatic ejection sequence.
