Abstract: "MULTI-PASSENGER AIRCRAFT SEAT  HAVING COMPOSITE PANEL FRAME"                               ABSTRACT           Improved, lightweight multi-passenger aircraft seating unit utilizes an elongated, generally S-shaped, composite panel to provide the sole support for the seat cushions, the seat back and seat back tray table, the seat belt anchors and the armrests.  Front legs and rear legs made of thin sheet metal can be attached directly to the panel by bolts passing through the panel.  A downwardly projecting front portion of the panel and an upwardly projecting rear portion, in cooperation with channel-shaped members bonded to the panel's peri-pheral edges, enhance the rigidity of the panel.  The unit provides cantilever support without the necessity for the front and rear tub-ular stretcher members and the fore and aft support members used in conventional seats.  The composite panel has a honeycomb core and its top and bottom skin surfaces are formed of continuous layers of resin-impregnated fibrous material such as graphite fibers, with additional swatches of such material overlying and integrally bonded into the skin.  The additional reinforcement material is laminated into regions of additional stress such as those where the legs, back, seat belt anchors and armrests are to be attached.  The seat back is doubly curved to provide lumbar and shoulder support and good comfort with a thin constant thickness rear pad.  The seat allows spacing between seat rows to be determined virtually solely by the dimensions of the occupants.

Abstract: PROCESS FOR DESILICATION OF ALUMIMATE LIQUORS       IN THE PRODUCTION OF ALUMINA                  A b s t r a c t The process consists of two desilication stages. In the first stage the aluminate liquor resulting from digestion of the sinter is subjected to an autoclave treatment to remove the major portion of impurities of SiO2 and Fe2O3. In the second stage the aluminate liquor is treated with a desilication agent comprising a lime pulp containing axides CaO, Al2O3, SiO2, Fe2O3, Na2O  in a mass ratio of CaO: (SiO2+Fe2O3) = 1,000 to 5,000:1 and Na2O:Al2O3 = 0.25-0.60:1, wherein CaO is active, Na20 - in the carbonate form. This lime pulp is employed in such an amount as to ensure the content of active CaO in the alu-minate liquor within the range of from 5 to 10 g/l. The impurities of SiO2 and Fe2O3 present in the liquor pass into the solid phase with the formation of calcium hydro-garnets of the formula 3 CaO(Al,Fe)2O3 mSiO2(6-2m)H2O. wherein m = 0.01-0.5 which are separated as a mud.

Abstract: PERPENDICULAR MAGNETIC RECORDING MEDIUM, METHOD FOR PRODUCING THE SAME, AND SPUTTERING DEVICE     ABSTRACT OF THE DISCLOSURE      Magnetic recording medium conventionally utilizes the in-plane magnetization mode, but, recently, the perpendicular magnetization mode utilizing the perpendicular anisotropy of an hcp cobalt alloy layer, in which C axis is oriented normal to the layer surface, is proposed.  The known perpendicular magnetic recording medium has been produced by an RF sputtering, but such medium is of too low flexibility to use it in the form of a magnetic tape.  In addition, the production rate of the perpendicular magnetic recording medium by RF sputtering is very low.     The perpendicular magnetic recording medium is very flexible due to particle pattern (Figs. 10, 12 and 13) completely distinct from the conventional columnar pattern (Figs. 8 and 11).  In addition, the production rate is high, because the base (20) is located beside a space between the targets (T1 , T2) of a sputtering device and further the magnetic field is generated perpendicularly to the sputtering surfaces (T1s , T2s) by a field coil (31) or magnets (32, 33).  The present invention makes it possible. to commercially produce the perpendicular magnetic recording medium, especially in the tape form.

Abstract: VALVE TIMING CONTROL DEVICE                      ABSTRACT OF THE DISCLOSURE   A  device  is  described  for  controlling  the  intake  and  exhaust valves of an internal combustion engine.  Separate valve actuators are provided for opening and closing the intake and exhaust valves of each cylinder of an engine.  Each such actuator is connected to a pair of cam actuated pumps for providing timed pulses of pressurized fluid to the valve actuators.  The cams which actuate the pumps are turned by a planetary gear mechanism which permits the incidence of pump actuation in relation to the rotation of a shaft turned by the engine to be varied.  The device permits close, precise and variable control of the valve  timing  of  the  engine  to  thereby  achieve  enhanced engine performance.                         SUMMARY OF THE INVENTION The present invention is directed to a device for controlling and varying  the  valve  timing  of  an  internal  combustion  engine.   More specifically, the invention  is directed to hydraulic valve actuators for opening and closing the intake and exhaust valves of the engine and hydraulic actuator pumps for supplying precisely timed pulses of fluid  to  the  actuators,  the periodic  action  of  the actuator  pumps being varied by advancing or retarding a planetary gear assembly in relation to the revolution of a rotating shaft turned by the engine.           BACKGROUND OF THE INVENTION Many  of  the  present  problems  in  society can  be  linked  to  the inefficient consumption of petroleum and the resulting rising cost and environment pollution.   Reduction of our petroleum consumption rates increases  the  health  of  our  society  and  economy.   In  addition, reduction  of consumption  rates  assures  that  more of this  valuable resource will be left for our prodigies to enjoy.  Even the quality of our environment and the air we all breathe would be improved by more fuel efficient transportation vehicles.    The  technologies  proposed  here  are  projected  to  provide  an increase in efficiency of the internal combustion engine vehicles from the present arena of approximately 30% to a realm of 75%
