Title: Method and apparatus for piled foundation improvement with freezing using down-hole refrigeration units
Inventor: SPALDING AUGUST V
IPC: E02D27/52
Filed: 1987-02-24
Granted: 1991-12-24
Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a method and apparatus for increasing the capacity of a tubular driven pile.  A refrigeration unit is lowered into the pile and grouted in place above a cement plug.  The area between the refrigeration unit and the plug is filled with a secondary refrigerant.  Seawater fills the pile above the refrigeration unit and is used for refrigeration unit cooling.  The refrigeration unit cools the brine until the soil surrounding the pile is frozen.  The adfreeze strength of the frozen soil and the pile increase the pull-out resistance of the pile.  Further, the end-bearing capacity of the pile is increased as a result of the large frozen mass surrounding the pile.

Title: Seat release mechanism
Inventor: PREMJI GULAM
IPC: B60N2/015
Filed: 1987-03-13
Granted: 1991-04-09
Abstract: ABSTRACT           The invention relates to a latching assembly for releasably securing a vehicle seat to a vehicle body and is adapted to co-operate with two generally parallel spaced mounting bars rigidly affixed to a vehicle frame forming part of the vehicle body.  The latching assembly comprises a bridge plate adapted for rigid attachment to the vehicle seat and dimensioned to span the distance separating a first and second of said two mounting bars.  The bridge plate has a first connecting slot for releasable, securing engagement with the first mounting bar and a second connecting mechanism for releasable securing engagement with the second mounting bar. The first connecting means comprises an open-ended slot formed in the bridge plate and adapted for surrounding engagement with the first mounting bar so as to permit pivotal movement of the bridge plate and the attached vehicle seat about the first mounting bar.  The second connecting mechanism comprises a pair of opposed movable jaw members pivotally mounted on the bridge plate for independent pivotal movement between a latchable configuration in which the jaw members are adapted to enclose the second mounting bar so as to restrain pivotal movement of the seat and an unlatchable configuration in which the jaw members are adapted to open from such enclosure so as to release the second mounting bar.  The vehicle seat can thus pivot about the first mounting bar for subsequent removal only when the jaw members release the second mounting bar.

Title: Compact chemical reaction vessel
Inventor: SZYDLOWSKI DONALD F
IPC: C01B3/22
Filed: 1987-12-11
Granted: 1991-09-10
Abstract: Abstract Compact Chemical Reaction Vessel The vessel is a fuel/steam reformer which has an annular chamber containing a catalyst bed.  The annular chamber is surrounded by a heating zone and heat pipes from the heating zone extend through the interior of the catalyst bed whereby the catalyst is concurrently heated from inside and outside of the bed.  A burner is positioned coaxially of the annular chamber to supply the required heat.  Raw fuel is fed into a vaporizing chamber below the catalyst bed and after vaporization, rises through the catalyst bed for conversion to a hydrogen rich fuel gas.  The fuel gas is collected in a chamber above the catalyst bed.  The device is particularly useful for compact methanol fuel cell power plants.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a travel path displaying apparatus for indicating the current position of an automobile running on a selected road in a road map appearing on an associated screen.  A cumulation of errors in estimating sequential current positions will cause an incorrect indication of the automobile's position on the screen and the automobile will depart from all the roads appearing on the screen.  In order to find the correct road on which the automobile is traveling it is necessary to carry out pattern matching between the travel trace and each of a number of selected roads, thereby determining which road is closest to the travel trace in shape.  The apparatus permits selection of the least possible number of roads for pattern matching, thus permitting quick determination as to the road on which the automobile is traveling and as to the direction in which it is traveling.

Abstract: ABSTRACT OF THE DISCLOSURE            For  convenient  packaging  of  plastic  bookbinding strips,  cassettes are provided.   The end edges of each strip are received in channels formed in opposed side rails.  The rails engage adjacent either end the depending  legs  of  transverse  spacer  bars.  The spacer bars have plural sockets to engage projections on the upper ends of the legs so that the spacing between  side  rails  may  be  varied  to  accommodate strips of different lengths - e.g., 8 1/2 inches, 11 inches, etc.   Different length legs may be used to accommodate  different  length  studs  formed  on the strips.    By  eliminating  the  legs  entirely,  flat female  binding  strips  may  be  packaged  in  the cassette.   A detent is provided in the ends of the rails preventing removal of strips until the detent is bent out of position.  The cassette is especially useful  in  equipment  which  mechanically  assembles punched sheets and strips preparatory to binding a book in a binding machine.
