Abstract: ABSTRACT OF THE DISCLOSURE         An air spring for motor vehicles including first and second end members, at least one of which is a piston, with an intervening flexible sleeve forming a fluid pressure chamber therebetween sealingly connected to the end members.  A continuous annular sealing band clamps at least one end of the flexible sleeve within an annular recess formed on the inside surface of an annular wall portion of one of the end members within an open end of the end member by compressing the sleeve material between the band and wall, and without deforming the band or wall of the end member beyond their elastic limits.   In one embodiment, the annular wall of the end member is formed of plastic and is deformed outwardly but maintained within its elastic limits upon insertion of the band within the open end. The end of the sleeve is rolled over the sealing band and then the sleeve end and band are inserted by a press plate into the open end of the end member with the band compressing and sealing the flexible material of the sleeve into the annular recess.  The compressed flexible material expands to seal the sleeve against the end member.  In another embodiment, the press plate expands the plastic material of the end member outwardly upon inserting the band and a rolled end of the flexible sleeve into the annular recess of the annular wall portion whereupon the wall attempting to return to its unstressed state seals the flexible sleeve between the sidewall and band.

Title: Fluid catalytic cracking regeneration with spent catalyst separator
Inventor: AVIDAN AMOS A
IPC: B01J8/26
Filed: 1988-09-21
Granted: 1992-06-02
Abstract: FLUID CATALYTIC CRACKING REGENERATION     WITH SPENT CATALYST SEPARATOR    ABSTRACT            An FCC regenerator separator separates spent catalyst from entrained hydrocarbons so that the hydrocarbons are not burned in the regenerator.  The spent catalyst is distributed into the regeneration zone in a manner which promotes uniformity of bed composition.  The spent catalyst is transferred to the regenerator separator by a stream of gas such as air, steam or flue gas which effects stripping of the hydrocarbons from the spent catalyst additional to that already effected by a conventional stripper.  The spent catalyst separation system in the regenerator may include primary and secondary separator cyclones linked by a closed conduit system which exhausts the hydrocarbons separated from the spent catalyst without co-mingling with the regeneration effluent gases in the main body of the regenerator vessel.

Abstract: ABSTRACT            Lock assembly particularly suitable for use on rental storage spaces and the like.  The assembly includes a lock bolt which is movable between extended and retracted posi-tions and a slide plate which can move with the bolt.  The slide plate is normally locked in a fixed position by a lock which is controlled by the owner of the rental space. The renter can lock the bolt to the slide plate to secure the space.  The owner-controlled lock permits the owner to release the slide plate and retract that plate along with the bolt to gain access to the space with the renter's padlock in place.  This lock also permits the owner to lock the bolt in the extended position so that the renter will no longer have access to the space even though he may remove his padlock.

Abstract: METHOD AND APPARATUS FOR CONVEYING MATERIALS IN BULK     BY LIQUID PRESSURE           ABSTRACT OF THE DISCLOSURE A method for conveying materials in bulk by li-quid pressure carried out by an appropriate apparatus involves loading a material in bulk into a chamber through a loading pipe and then supplying liquid un-der pressure through a pipe for supplying liquid in the form of a downward annular flow, and discharging the material in bulk in an upward flow through a dis-charge pipe mounted to extend coaxially with, and inside the pipe for supplying liquid. A zone of recir-culation flows of liquid is formed in the chamber by swirling the annular flow to an extent determined by a ratio of the rotational component of velocity to the axial component of velocity at least equal to 0.4. The material in bulk is discharged in the zone of reoir-culation flows. For swirling the annular flow, an inlet port of the pipe for supplying liquid is located in the periphery thereof, and the axis of this port is off set with respect to the axis of the discharge pipe. The inlet and outlet ports of the pipes for ma-terial discharge and liquid supply, respectively, are located at predetermined level with respect to each other.
