Title: Deceleration and pressure sensitive proportioning valve
Inventor: GAISER ROBERT F
IPC: B60T8/28
Filed: 1986-10-21
Granted: 1991-08-20
Abstract: DECELERATION AND PRESSURE-SENSITIVE        PROPORTIONING VALVE               ABSTRACT OF THE DISCLOSURE          A proportioning valve assembly  (10,  130)  in a housing (12) is pressure responsive to control the  flow of fluid to a wheel brake cylinder.   The proportioning valve assembly (10, 130) includes a movable retainer (50) coupled  with  a  differential  piston  (30)  for  movement therewith,  a  stationary  retainer  (70)  mounted  by  the housing (12) and surrounding a second piston (80) having an enlarged diameter portion  (88)  that defines with an end  (11,  16)  of the housing  (12)  a chamber  (90).  The second piston  (80) has a poppet  (84)  extending into an interior opening (54) of the movable retainer  (50),  the movable retainer  (50)  supporting  a seal  (56)  disposed about the extension (82) of the second piston (80).  The seal  (56)  is positioned for closing an opening  (73)  of the  stationary  retainer  (70)  through  which  the  second piston (80) extends.  The second piston  (80) contains a poppet valve  (99)  which controls  fluid  flow  through  a passage (85) from one side of the second piston (80) to the other side, and the second piston (80) provides sup-port for an inertia-sensitive object (110) which controls operation of the poppet valve (99). When the differential piston (30) and movable retainer (50) move in response to inlet fluid pressure and the seal (56) closes the opening (73) of the stationary retainer (70), fluid on both sides of the enlarged diameter portion (88) of the second pis-ton (80) is isolated from the inlet fluid pressure, and resulting deceleration of the vehicle causes the inertia-sensitive object (110) to move and close the poppet valve (99) to trap fluid pressure within the chamber (90) and prevent further movement of the second piston (80).

It comprises, generally, a substrate, such as paper, cardboard or plastic and a deposit of silica aerogel particles releasably bonded to the substrate.          The strength of the bond prevents the silica aerogel particles from being released by air currents but allows the particles to be picked up by some insects that contact the deposit.      Depending on the place of exposure of the device, crawling and/or flying insects may be controlled by the insecticidal action of the silica aerogel.

Abstract: Abstract An integrated refining scheme is disclosed for hydroprocessing high boiling fractions such as gas oil and catalytically cracked cycle oils to produce premium quality distillates, especially jet fuels and naphthas suitable for reforming into high octane gasoline.  The integrated hydroprocessing comprises a first stage hydrocracking step employing an aromatic selective hydrocracking catalyst based on a large pore size acidic component such as amorphous alumina or silica alumina or a large pore size zeolite such as zeolite X or zeolite Y.  The hydrocracking may be operated either in a naphtha directing mode under conditions of moderate to high severity or under conditions of low to moderate severity to produce a relatively higher proportion of product boiling in the middle distillate range.  The unconverted fraction from the hydrocracking step is passed to a second step in which it is hydroprocessed over a zeolite beta catalyst with additional hydrogenation-dehydrogenation functionality.  In this stage, the paraffins remaining in the feed are converted by the zeolite beta into isoparaffins and conditions may be controlled to favor hydroisomerization over hydrocracking so as to increase the yield of middle distillate product, especially of highly isoparaffinic jet fuels and diesel fuel.

Inventor: MEYER RICHARD
IPC: D21F5/04
Filed: 1988-02-26
Granted: 1992-02-11
Abstract: ABSTRACT In a device for stabilizing the run of a material web, which successively runs over two rolls, namely a delivering and a receiving roll, there is a box provided that extends between the delivering and the receiving roll across the width of the paper web. This box has a so-called guide wall that extends along the course of the material web, with an air gap remaining between the guide wall and the material web.  Additionally provided on the box are means which create a vacuum in the air gap.  In a device of this type, the guide wall is shaped in a way such that its spacing from the theoretical trajectory plane tangent to the two rolls is in the center area of the material web greater than it is in the area of the material web edges.  A device of this type serves to better stabilize the smooth running of the material web on its way between the rolls.  A preferred applicational area of the invention is an air guide box      for the drying section of a high-speed paper machine where the paper web      to be dried meanders together with a backing belt      over drying cylinders.

Abstract: Abstract A bandmill has first and second wheels and an endless saw blade trained about the wheels.  The wheels are mounted to rotate about respective axes which lie in a common plane, but the first wheel is adjustable in position relative to the second wheel with respect to both its distance from the second wheel and its orientation relative to the second wheel.  A tensioning mechanism is effective to force the first wheel away from the second wheel, while maintaining the axes of rotation of the two wheels substantially parallel, in response to a signal which is provided by a load cell and repre-sents the tension in the saw blade.  A wheel tilt mechanism is effective to adjust the angular posi-tion of the first wheel relative to the second wheel in response to a signal indicating the path followed by the saw blade, for maintaining the blade on a proper path.
