Title: Clamp for multi-strand cable with positive strand  engagement
Inventor: SACHS ISAAC
IPC: F16B2/02
Filed: 1984-03-19
Granted: 1987-04-14
Abstract: Abstract of the Disclosure A clamp for multi-strand cable comprises a pair of opposingly disposed clamping members each having an edge bent to define a jaw means forming a longitudinal passage for gripping a multi-strand cable extending therethrough, the clamping members being engaged with one another to permit movement of the jaw means between open and closed positions, and releasable coupling means interconnecting the clamping members and operable to bias the jaw means to the closed position for releasable securing the cable in clamping engagement between the jaw means.  The bent edge of each clamping member is formed with a tooth which is inclined relative to the longitudinal axis of the passage so as to engage the cable between two successive outer strands thereof, thereby providing a positive strand engagement and preventing the clamping members from pivoting about the cable as well as sliding therealong.

Abstract: ABSTRACT OF THE DISCLOSURE:              An I.D.R. process for the manufacture of urea, comprising a high pressure loop and a subsequent low pressure loop.  The (high pressure) loop comprises synthesis reactor wherein NH3 and CO2 are reacted to produce urea.  The effluent leaving the reactor is fed into a first isobaric stripper to produce a first solution containing a strong NH3 excess (NH3:CO2 > 6 by moles) and a low CO2 precentage (CO2:urea < 25% b.w.). This first solution is fed into a second isobaric stripper to produce a second solution containing an amount of ammonium carbamate lower than the amount of carbamate contained in the first solution leaving the first stripper.  The overproduction of carbamate in the second stripper releases such an amount of heat as to displace a major proportion of the residual NH3 excess contained therein.  The second solution leaving the second stripper is flashed at 20-30 ata and enters a first (medium pressure) still forming part of the low pressure loop. This first still is heated by a low pressure recovery steam, coming from an isobaric condensation wherein the vapors leaving the top of the second stripper are condensed.  This recovery steam has a thermal level sufficient to decompose at least the overproduction of carbamate.  The solution leaving the first still is flashed substantially at 5 ata and enters a second, low pressure still and then a vacuum concentrator. The heat recovered from the vapors leaving the head of the first still is used for operating the second still and vacuum concentrator.
