Title: Thermally stable compositions and lubricants and functional fluids containing the same
Inventor: VINCI JAMES N
IPC: C10N30/12
Filed: 1992-04-07
Abstract: This invention relates to a composition, comprising: (A) at least one basic alkali or alkaline earth metal salt of an acidic organic compound; (B) at least one metal deactivator other than dimercaptothiadiazole or derivatives thereof; and (C) at least one hydrocarbyl phosphite, wherein the ratio of the equivalents of (A) based on the total base number to the equivalents of (C) based on phosphorus atoms is at least one, provided that the composition is free of zinc dithiophosphate and provided that when (A) is an overbased magnesium salicylate then the composition contains (D) up to about 0.40 % by weight of a sulfur-, phosphorus-, or sulfur-and phosphorus-containing antiwear agent. These compositions are useful as additives for lubricants and functional fluids, particularly hydraulic fluids, gear oils, greases and the like. The lubricants and fluids having this particular combination of components have improved thermal stability and do not contain zinc dithiophosphate. These lubricants and fluids are also not corrosive to the hydraulic system components.

Title: Compensated, sbs-free optical beam amplification and deliver apparatus and method
Inventor: ROCKWELL DAVID A
IPC: H04B10/2587
Filed: 1992-12-18
Abstract: An optical beam amplification and delivery system and method employs a central station (2) with a laser oscilla-tor (8), a laser amplifier (24) and a phase conjugate mir-ror (PCM) (26).  Low power, near diffraction limited laser beams are delivered to each of a plurality of local sta-tions (4) through single-mode polarization preserving fi-bers (12).  From the local stations (4) the low power beams are transmitted back to the central station (2) through high power multi-mode optical fibers (18).  At the central station (2) the received beams are amplified, phase conju-gated and transmitted back through the amplifier (24) and multi-mode fibers (18) to their respective local stations (4).  Distortions imposed upon the beams by the multi-mode fibers (18) during transmission back to the central station (2), and by the amplifier (24), are compensated during the return path, providing high power yet near diffraction lim-ited beam quality at the local stations (4).  Attenuation through stimulated Brillouin scattering (SBS) is inhibited by selecting an appropriate aggregate diameter for the mul-ti-mode fibers (18).

Patent CA-2097229-A1 (CA)
Inventor: CASSIDY RONALD F
IPC: B01D53/26
Filed: 1993-05-28
Abstract: ABSTRACT OF THE DISCLOSURE            The removal of components from fluid mixtures in aircraft utilizes an adsorbent bed which is regenerated by passing dry  ambient  air  through  the  adsorbent  bed  when  the aircraft reaches a height at which such dry ambient air is available.  An example of mixtures that can be treated in this way are water/oil mixtures, air/water vapour mixtures and air/odour mixtures.  By periodically regenerating the adsorbent bed in this way, an adsorbent bed of small size can be used but yet have a substantial life.

Patent CA-2100071-A1 (CA)
Title: Rolling door
Inventor: SJOESTROEM ALBIN
IPC: E06B9/56
Filed: 1992-01-09
Abstract: A roll-up door comprises a flexible door leaf (1) which is rolled up round an upper roller (2) and which, when unrolled therefrom, closes a door opening. A motor turns the roller (2) in both the unrolling and the rolling-up direction. Two upper pulleys (4), which are coaxial with the roller (2), are disposed one at each end of the roller so as to turn with the roller. Two ropes (6), each travelling over a lower pulley (5) provided in the lower part of the door opening, are, at one end, fixed to the free end of the door leaf (1) and, at the other end, fixed to an upper pulley (4) each, so as to be rolled up round the upper pulley when the roller (2) is turned in the unrolling direction and be unrolled from the upper pulley when the roller is turned in the rolling-up direction. The two upper pulleys (4) are of larger diameter than the roller (2). The upper pulleys (4) are connected to the roller (2) by a spring means (7) which is adapted, when the roller (2) is turned in the unrolling direction, to entrain the two upper pulleys (4) in this movement. The spring means (7) is so mounted that its spring tension increases when the roller (2) is thus turned owing to the fact that the upper pulleys (4) turn more slowly than the roller because of the difference in diameter.

Patent CA-2105061-A1 (CA)
Inventor: LEWIS MARTIN
IPC: B63C11/50
Filed: 1992-04-16
Abstract: 2105061 9218380 PCTABS00016 This invention relates to a Grapnel which is particularly intended for recovering telecommunications cables from the deep oceans.  The Grapnel has special features in that it treats the cable gently, and that it cuts the cables and holds a predetermined side.  The Grapnel comprises a rotor (10) which is adapted for rotation about a longitudinal axis of the Grapnel. The rotor is located between two cutting stations (11 and 12). The rotor is preset for rotation in either the clockwise or the anti-clockwise direction.  In operation, the rotor (10) acquires one run of cable from below and this run of cable is held clear of both cutting stations (11 and 12). The rotor (10) acquires the other run of cable from above, and this run of cable is introduced into one of the cutting stations. After winding, both cutting stations are actuated, and a predetermined run is cut. The other predetermined run is held because it is wound round the rotor and it can be retrieved to the surface. It should be appreciated that the direction of rotation of the rotor decides which end is cut and which end is held, and the direction of the rotation remains the same even if the Grapnel deploys upside-down.

IPC: B01D5/00
Filed: 1994-02-17
Abstract: An apparatus removes water from a liquid mixture which has formed in a compressed gas system.  The apparatus includes a gas compressor having an inlet port for receiving low pressure gas to be compressed and a discharge port through which a stream of compressed gas flows.  An aftercooler is disposed in fluid communication with the discharge port for cooling the compressed gas stream.  A vessel collects any entrained liquid water and lubricant from the compressed gas stream.  The vessel has a sump portion and a vent to an atmosphere external to the compressed air system.  A heat exchanger heats the liquid mixture within the vessel to a predetermined temperature to vaporize the water.  The water vapor exits the vessel through the vent and the lubricant remains in the sump portion of the vessel.  A valve permits the separated lubricant to be drained from the sump portion of the vessel to a location external to the compressed air system.
