Abstract: HYDRODESULFURIZATION PROCESS  EMPLOYING A GUARD CHAMBER                 Abstract of the Disclosure A process for hydrodesulfurizing a residual oil by passing the oil downwardly through a catalytic reaction zone at a hydrogen pressure which is sufficiently high that de-metallization occurs rapidly so that at end-of-run the up-stream catalyst region is more nearly metals-saturated than the downstream catalyst region.  At the end of the catalyst cycle, the more nearly metals-saturated upstream portion of the catalyst is removed from the process while the less nearly metals-saturated downstream portion of the catalyst is passed to a guard chamber where during further operation of the pro-cess it approaches metals-saturation. In this manner, no portion of catalyst is removed from the process until it has an elevated metals content.

Abstract: ABSTRACT OF THE DISCLOSURE   A terminal clamp assembly including a clamp having an unround outer contour and clamping projections for clamping electrical conductors to a con-tact element.  The clamp is secured between confining walls in the assembly by a screw releasably engaged with the contact element and extending through an opening in the terminal clamp.  The clamp is tiltable against the screw for equalizing different electrical conductor diameters, and the clamping projec-tions are disposed in the center of the underside of the clamp and extend to the lateral edges of the clamp disposed adjacent the confining walls.  The improvement of the invention comprises the clamp including center areas and outer areas disposed along opposing lateral edges of the clamp.  The center areas are disposed between a pair of the outer areas along each of the lateral edges of the clamp and are inwardly recessed towards the opening in the clamp with respect to the outer areas.  The projection members extend to the lateral edges of the clamp along the center areas and are thereby prevented from enga-ging the confining walls during tilting of the terminal clamp.

Abstract: SHUTTLE VALVE                    Abstract of the Disclosure A shuttle valve comprising a valve body having an elongated bore and a plurality of ports in the side wall of the bore.  A control port is located at each end of the bore surrounded by a valve seat.  A shuttle valve member slides axially in the bore between the two valve seats to control the flow of fluid between the side wall ports.  Bleed passageways provide high pressure fluid to chambers in the bore adjacent to the control port valve seats.  A control device, such as a solenoid valve, alternatively connects one control port to a low pressure region and blocks the other, or vice versa, to cause the valve member to move between positions in which it engages one or the other control port valve seat.  The ratio of the cross-sectional area of the valve member to the cross-sectional area of the valve seats is relatively small, i.e., the valve seats are of relatively large diameter although the control ports are small.  The ratio of valve member area to valve seat area is in the range between 2 to 1 and 4 to 1, and is preferably no more than 3 to 1.
