Patent BG-51115-A1 (BG)
Title: Process for vacuum nitriding of high-speed steel
Inventor: UZUNOVA VELIKA M
IPC: C23C8/26
Filed: 1991-01-23
Abstract: The method is applicable in the machine manufacturing industry for thermochemical treatment of tools, made from high-speed steel. It prevents the formation of brittle nitride phases upon reduced process duration. It also increases the impact toughness and durability of the steel in operating conditions. The nitriding is carried out prior to hardening the steels at a temperature from 600 to 750 degrees C for 15 to 30 minutes and a pressure of ammonia of 9.3-16.0 x 10<3>Pa. Immediately after the nitriding, the heating process continues in the same furnace until the hardening temperature is reached, which is followed by triple tempering. If the vacuum furnace cannot provide enough heat for hardening, the steel is cooled slowly and the hardening and tempering processes are carried out in other facilities.

Title: Attenuation touchant au domaine electrique d'effets dependant de la polarisation dans un systeme optique de communication
Inventor: ROBERTS KIM
IPC: H04B10/508
Filed: 2003-10-03
Abstract: On compense les effets dépendant de la polarisation (PDEs), comprenant la dispersion en mode polarisation (PMD) et les pertes dépendant de la polarisation (PDL) imposées à un signal optique traversant une liaison optique en traitant un signal d'entrée du domaine électrique avant l'émission et en en tirant une fonction de compensation qui compense partiellement les PDEs. On traite le signal de communication du domaine électrique à l'aide de ladite fonction de compensation pour produire un signal électrique prédéformé qui  module une source optique pour produire un signal optique prédéformé transmis à travers la liaison optique. Les PDEs de la liaison optique traitent le signal optique prédéformé de manière à pouvoir recevoir un signal optique non déformé à l'extrémité réceptrice de la liaison.

Title: Methods and apparatus for the continuous formation of an extruded product

Abstract: PCT No. PCT/GB90/00025 Sec. 371 Date Aug. 31, 1990 Sec. 102(e) Date Aug. 31, 1990 PCT Filed Jan. 9, 1990 PCT Pub. No. WO90/08024 PCT Pub. Date Jul. 26, 1990.In a method and apparatus for formation of an extruded product from material containing fibrous, molecules or other constituents succeptable to alignment, while the extrudate is still molten and moving through the die (5), in the direction of the extrusion axis (11), it is subjected to pulsating displacements in a direction transverse relative to that axis. These displacements give rise to a shearing action within the material, resulting in a degree of transverse orientation of the constituents. This orientation may be "locked in" to the extruded product when the melt solidifies (40), so improving the transverse strength of that product, and/or may correct an unwanted orientation (from 112, FIG. 16) that existed in the melt upstream of the point where the pulsating displacements were applied. The displacements may be applied by the synchronized operation of pistons (20-27), operating in chambers (17) which open into the die cavity (18) at separated locations all lying in the same transverse plane. The extrusion of products of rectangular, tubular and other sections is described, as are various methods (8a, 8b, 9, 10, 37) of applying forced cooling to the die to accelerate the solidification of the molten product.

Patent CA-2023782-A1 (CA)
Inventor: CARIS JOHN R
IPC: B01D17/00
Filed: 1990-08-22
Abstract: A process for separating emulsified, suspended and separate oil as well as other contaminants from the water phase of a compressed air system condensate comprises the steps of discharging air and condensate from a compressed air system into a water filled separation tank where air is separated from the condensate.  Some of the contaminants heavier than water are allowed to settle to the bottom of the separation tank while lighter oil contaminants are allowed to float to the surface where they are removed.          Water and the remaining contaminants which did not flow to the surface or settle to the bottom of the tank are drained away until a given amount of liquid mass has been accumulated.  Pressure applied to the liquid mass forces the mass into and through an underwater coalescing media.          Such action causes substantially all of the remaining oil constituents to coalesce and thereby form a floating oil phase while other contaminants are retained by the coalescing media.  The floating oil phase is removed and the remaining water is relatively pure.

Abstract: A control system and method utilizing a race between two responses to a changing stimulus are disclosed.  An example of a changing stimulus is pressure which increases at a decreasing rate of change during a closed-in period of a drill stem test in an oil or gas well.  In a preferred embodiment two components are moved  in different directions,  but in a net first direction, until the rate of change of the pressure is sufficiently low (e.g., near steady state), at which time the rates of movement of the two components produce net movement in a second direction.          In a preferred embodiment, the change in direction of the net movement moves  a control valve which communicates  a pressure control signal for opening a bypass valve to commence a flow period of the drill stem test.
