Patent CA-1309888-C (CA)
Title: Roller press with a device for the relief of the pressure roll
Inventor: HAFNER PAUL
IPC: D21F3/06
Filed: 1988-04-28
Granted: 1992-11-10
Abstract: F-6404 (14-129) ROLLER PRESS WITH A DEVICE FOR THE RELIEF OF THE PRESSURE ROLL            ABSTRACT OF THE DISCLOSURE          A roller press has a press roll and at least one pressure roll applying pressure to it.  In the end region of each pressure roll, there is an associated positioning cylinder.  The positioning cylinders re-lieve the pressure of the pressure roll against the press roll automatically upon an impermissible increase in the operating pressure in the positioning cylinder. For this purpose, each positioning cylinder has a safe-ty valve which is operated either by the working fluid in the positioning cylinder to the pressure relief con-dition or by an electrical signal, in different embodi-ments, to relieve pressure in the positioning cylinder. The safety valves are coupled to each other by a signal line. When one safety valve relieves one positioning cylinder, all of the positioning cylinders are re-lieved.  Details of the working fluid operated safety valves and of the electrically operated safety valves are disclosed, including details of the valve body and the application of pressures upon the valve bodies which causes them to shift.

Abstract: SWEEPLINE ROLLER-STOPPER                    Abstract of the Disclosure A sweepline roller-stopper connects a sweepline to a bottom trawl while stopping lateral movement of rollers along the sweepline.  In a preferred embodiment, the roller-stopper includes a tubular body member having a large washer welded to an end and a tang welded to a side.  A bolt passing through the body member fixes the position of the roller-stopper on the sweepline chain.  The roller (or a spacer) abuts the washer, which resists the lateral forces exerted by the roller.  In another embodiment, a ring having a tang freely rotates about the body member, while the body member is fixed to the sweepline chain.  The roller-stopper is rugged, resists wear, and prevents the trawl net from becoming tangled with the sweepline.

Title: Nondestructive holographic reconstruction
Inventor: REDFIELD STEPHEN R
IPC: B41M5/26
Filed: 1989-08-10
Granted: 1993-09-14
Abstract: ABSTRACT OF THE DISCLOSURE   method for promoting enhanced nondestructive reconstruction of holograms recorded in photorefractive media (10) involves control of the polarization states of the reconstruction beam (24) and the recording beams (24, 26), control of the cummulative recording energy, and use of a relatively high external field applied across the media (10) during recording which is subsequently reduced during reconstruction.  The resulting reconstruction history characteristics are selectively tailored by adjusting the polarization and intensity of the reconstruction beam (24), the recording geometry, and the applied voltage (40) during reconstruction and recording, and various other parameters.  In general, the reconstruction efficiency (48) starts at a relatively high level, initially reduces, and then subsequently grows above the starting values, and and be made substantially nondestructive over a typical reconstruction cycle, with erasure times exceeding forty-five minutes.
