Abstract: APPLICATION OF: THOMAS J. ALEXANDER              AND WALTER (NMN) WILSON             FOR: SELF ADJUSTING HOIST BRAKE     A B S T R A C T    A hoist brake with an incremental self adjusting feature.          The brake has interdigitated plates which will stop a driven shaft when engaged and allow the shaft to rotate when not engaged.  The brake is normally biased into an engaged position and means, such as, an electromagnet is provided to disengage the brake.    A sensing means is provided which measures the gap traversed by a portion of the brake when the brake is activated, the traverse indicating the amount of wear which has taken place since the last adjustment.  When the amount of wear is greater than a predetermined amount, the distance between the electromagnet and associated plate on which it acts is incrementally reduced the next time the brake is activated to adjust the gap and insure continued proper performance.

Abstract: ABSTRACT:            A small haze around the spot on the display screen in the corners and at the edge of the display screen is obtained by causing the first grid to form a multipole lens in cooperation with the cathode, which lens mainly is a first quadrupole lens and in cooperation with the second grid also forms a multipole lens which is also a mainly second quadrupole lens and which is rotated 90° with respect to the first quadrupole lens. Such a system of lenses in the first grid can be formed, for example, by giving the aperture in the first grid an elongate cross section both on the side of the cathode and on the side of the second grid, the long axis of said elongate cross-section on the side of the cathode extending substantially at right angles to the long axis of the elongate cross-section on the side of the second grid.

Abstract: Abstract of the Disclosure An improved method of recycling asphaltic concrete comprises heating the material in a rotating drum while directing flame and hot gases of combustion therein whereby the composition is directly exposed to the hot gases, directing the hot gases into the drum through a port, open to atmosphere, burning hydrocarbon volatiles from the composition in the drum, and venting exhaust gases and burned hydrocarbon volatiles to atmosphere  from the drum through the open port concurrently with the introduction of the hot gases of combustion.  In an improved apparatus for practicing the process, the drum includes a second port adjacent the opposite end of the drum from the open port, the second port having closure means for being selectively opened only to the extent necessary to recover the heated composition.

SOLID ELECTROCHROMIC DEVICES            Abstract of the Disclosure Solid state electrochromic devices are fabricated using, as the electrochromic material, ionic conductors such as heteropoly acids. The properties of the ionic conductors permit construction of a device having only two electrodes and the electrochromic material.

Abstract: ABSTRACT OF THE DISCLOSURE               A hydraulic valve in a load responsive pressure flow compensated system for operating a header height cylinder including a lockout check valve which is opened by an accompanying plunger experiencing pressure in an adjacent motor port.  Said plunger includes a metering notch opening to drain when the plunger is actuated, said metering notch is sized larger than the flow-sensing notch on the valve spool so that while lowering the machine header, the pressure compensating means of the system does not go to full pressure compensation level but rather stands by at the low pressure level relieved across the lockout actuating plunger.  The valve further includes metering notches in the control valve spool which are so shaped that a FLOW vs. TIME curve of the spool from the neutral position to an opening position has a plateau at as time interval from zero which is substantially equal to one-half of the cycle time of the natural frequency of the machine.

Abstract: Improvements in or relating to Visual Display Apparatus ABSTRACT     The invention provides head-coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators.  The apparatus provides a stereoscopic pair of images for both a pilot and co-pilot, projected onto the inside of a part-spherical shell, which carries a concave retro-reflective screen and surrounds the two pilots.  The displayed scenes cover an area of interest centred upon each pilot's line of view.  A separate image generator is used for each pilot and may be of the computer generated image, laser-scanned model or closed-circuit television type.  For stereoscopic viewing a modified image is provided for each eye of each pilot and for each pilot the two images are separately projected from points on a respective pilot helmet above the eye positions.  Line scan apparatus is mounted in the pilots' cockpit; line image transmission is by two pairs of fibre optic light guide ribbons; and frame scan apparatus is mounted on the two pilots' helmets. Sensing means detect head/helmet movements of each pilot to permit voluntary individual scanning of a wide angle of simulated view from the craft.     P.2093/1
