Title: Damping valve for air spring suspension systems
Inventor: GENO WAYNE H
IPC: B60G15/14
Filed: 1988-01-22
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE     An air spring for motor vehicles to absorb road shocks includes first and second axially spaced end members with an intervening flexible sleeve forming a fluid pressure chamber therebetween.  An improved two-way damping valve connects the pressure chamber to a fluid reservoir and provides damping for the air spring by restricting fluid flow in one direction, either into or out of the pressure chamber, without materially effecting the fluid flow in the opposite direction.  The valve includes a flexible diaphragm formed of reinforced rubber having slots which provide one or more flaps.  The diaphragm preferably is mounted on a rigid annular washer having a predetermined size center opening forming a damping orifice.  The flaps are drawn automatically into the washer opening to restrict the fluid flow through the orifice when the fluid moves in one direction, with the flaps moving away from the orifice to permit free movement of the fluid therethrough when the fluid is moving in an opposite direction.  In another embodiment the damping valve is mounted in a strut-type fluid shock absorber combined with an air spring.

Title: Base-bleed gas generator for a projectile, shell or the like
Inventor: FRANZEN ARNE
IPC: F42B10/40
Filed: 1988-02-09
Granted: 1992-02-11
Abstract: ABSTRACT          The invention relates to a supporting cupola (11) for the propellant (6) of a base-bleed gas generator for a projectile, shell or the like.   The supporting cupola (11) is arranged in the discharge aperture (7) of the gas generator and provides a reduced gas outlet area from the base-bleed combustion chamber (4) during launch of the projectile.   The supporting cupola (11) is made of a material which is easily eroded by the hot combustion gases, such as magnesium.   The reduced outlet area increases the pressure in the combustion chamber during the acceleration stage of the projectile so that an improved ignition of the propellant (6) and reduced risk of extinguishment is obtained.   Due to erosion of the cupola material the outlet opening area increases with time providing a regressive burning rate of the propellant which means an increased base-bleed effect with respect to the firing range of the projectiles.

Abstract: ABSTRACT OF THE INVENTION           This invention relates to a method for thin film coating a substrate.   The forward end of the substrate is detected  to  produce  a  detection  signal  at  a  detection position which is before a tacking  position.   While the substrate is being conveyed from the detection position to the tacking position, tack members are brought close to a surface of the substrate to tack the forward end portion of a web of thin film to the forward end of a surface of the substrate.  Conveyance of the substrate is stopped after the forward  end  of  the  substrate has  been conveyed from the detection  position  to  the  tacking  position.   After  the forward  end  of  the  substrate  is  stopped  at  the  tacking position compression-bonding rollers rotate at the tacking position to convey the substrate and adhere the forward end of  the  thin film to the surface of the substrate at the forward end of the substrate.  While said tacked thin film is  being  adhered  to  said  surface  of  said  substrate,  the compression-bonding  rollers  are  moved  from  the  tacking position to near a standby position where the compression-bonding  rollers  do  not  touch  the  tack member  to make compression-bonding contact with the forward end portion of the tacked thin film after the tack members are moved away from the surface of the substrate.
