Title: Elastically restoring knee bolster for motor vehicle
Inventor: BRANTMAN RUSSEL
IPC: B60R21/045
Filed: 1987-04-10
Granted: 1992-03-17
Abstract: ABSTRACT OF THE DISCLOSURE     In  an automobile,  a  knee  bolster  is  provided,  with either an airbag or shoulder belt, for capturing and absorbing the translational kinetic energy of the occupant's lower torso, for prevention of submarining, and for controlled rebound.  The bolster  includes  a  member  for  capturing  and  dissipating  a portion  of  the kinetic  energy  of  an  occupant  during  a collision,  and a member  for  storing another portion of  said kinetic energy.  A collision between the lower portion of the body of the occupant and the bolster tends to restore the body in  such  a way  that  the  rebound  impact  against the  seat  is applied to the occupant's back rather than his head or neck.

Abstract: DRUM WELDING APPARATUS                    ABSTRACT OF THE DISCLOSURE       An apparatus is disclosed for automatically welding sheet metal panels to form part of a revolving drum for concrete transit mixers.  The apparatus includes a fixture having an annular central core, linear and generally longitudinal ribs extended away from the core, and circumferential ribs extended radially outwardly of the core.  The ribs intersect to define compartments in the fixture which are closed when the sheet metal panels are placed on the fixture.  The compartments are then evacuated, creating a pressure differential to fix the panels on the fixture.  A welding carriage is slidably supported on a rail above the fixture.  The fixture can be tilted to selectively align panels along the rail for welding linear seams.          Circumferential seams are welded by rotation of the fixture while the carriage is held stationary.  To more positively maintain the panels in place during welding, compartments along the interfacing edges of adjacent panels are subjected to a higher vacuum.

IPC: E02D31/00
Filed: 1989-05-02
Granted: 1993-03-23
Abstract: ABSTRACT          A method and system is disclosed for reversibly establishing a closed, flow-impervious cryoqenic barrier about a predetermined volume extending downward from a containment site on the surface of the Earth.  An array of barrier boreholes extend downward from spaced apart locations on the periphery of the containment site. A flow of a refrigerant medium a established in the barrier boreholes whereby water in the portions of the Earth adjacent to the barrier boreholes freezes to establish ice columns extending radially about the boreholes.  The lateral separations of the boreholes and the radii of the ice columns are selected so that adjacent ice columns overlap.  The overlapping ice columns collectively establish a closed, flow-impervious barrier about the predetermined volume underlying the containment site. The system may detect and correct potential breaches due to thermal, geophysical, or chemical invasions.

Abstract: ABSTRACT OF THE DISCLOSURE   A vacuum skin package for packaging fresh red meat and like articles is produced by using a composite, multilayer, oxygen barrier, vacuum skin package forming film in which the barrier layer can be manually separated from the  non-barrier,  oxygen permeable  layer.   After  the vacuum skin package is formed to enclose a fresh red meat product in a vacuum the meat will have a purplish color.  Then, after storage, the barrier layer can be removed so that the remaining permeable film can admit oxygen to impart the desirable red bloom to the fresh meat.   Of importance is the "tear through"  feature of the permeable inner layer which has a greater bond strength  to  the  tray  than  internal  strength  or  layer-to-layer  bond strength so that a tab may be torn loose at a score line and then the barrier layer may be readily delaminated and peeled from the permeable layer.

Abstract: The process for depositing an adherent silver film, especially on a nonconducting substrate, involves depositing the silver film from the gas phase.  A plasma discharge in a gas containing volatile silver organic compounds is used. The silver compounds advantageously contain silver atoms which are bonded to an sp2-hybridized carbon atom and are halogen-containing, particularly fluorine-containing compounds.  The compounds CF3-CAg=CF-CF3, CF3-CAg=CF2 and pentafluorophenyl silver may be used.  The silver film so formed may be strengthened electrochemically or by chemical reduction.  The silver film products are useful as electrically conducting, decorative or reflective layers.
