Title: High capacity tray for gas-liquid contact apparatus
Inventor: NUTTER DALE E
IPC: B01F3/04
Filed: 1994-06-15
Abstract: In a crossflow gas-liquid contact tower, liquid moves horizontally across a plurality of vertically spaced trays (2), and downwardly from tray-to-tray while gas flows up through openings in the trays to create a liquid-vapor mixture in an active bubble area. Each opening includes an aperture (16) in the plane of the tray, and a deflector (18) which overlies the aperture to define lateral vapor outlet slots (22). The aperture (16) is wider at its upstream end than at its downstream end;  and, the deflector (18) has upstream and downstream portions (18u, 18d) which extend across the ends of the aperture. The deflectors can be stationary or they can be vertically movable valves.

Patent CA-2152739-A1 (CA)
Inventor: WOOD JAMES A
IPC: B60T8/58
Filed: 1995-06-27
Abstract: This invention is a proportional force modulation wheel slide protection process for steel wheel/steel rail vehicles.  It applies particularly to self-propelled transit type railway vehicles. It uses a slide detection logic which predicts the force reduction needed to control slippage and correct the slide condition.  The force modulation is made on the basis of the initial prediction and the time that a slide has been in effect to determine if greater force reduction is needed to effect a slide correction. Sensing of positive to negative axle rate polarity shift is used to determine when a slide has been corrected and normal braking force can be restored.  This process is used to control slides by modulating both the dynamic and friction braking in like manner.  The normal braking control devices are used to reduce braking force during slide correction.   Although this process could be implemented through  the  use  of  discrete  circuits,  it  lends  itself  to microprocessor applications.

Title: System and method utilizing low-pressure nozzles for extinguishing fires
Inventor: TIRRONEN HANNU
IPC: A62C3/00
Filed: 1994-09-09
Abstract: It is possible to more effectively extinguish fires in confined spaces such as engine rooms of ships. General nozzles are disposed above and/or on the sides of the confined space to be protected for general fire extinguishment in the confined space. Spot nozzles may be disposed around specific objects which are susceptible to fire in the confined space, such as engines in an engine room. At least some of the nozzles are low pressure nozzles having wings from which extinguishing water is sprayed at a pressure less than twelve bar, e.g., between 2-12 bar, having water droplets of various size. Due to rotating action of the wings, the water droplets are distributed in the water spray so that the frequency of drops having larger diameters is greater at the periphery of the water spray than in the inner part of the spray, and correspondingly, the frequency of drops having smaller diameters is greater in the inner part of the spray than at the periphery.

Inventor: WHITE KENNETH M
IPC: E21B33/128
Filed: 1996-07-12
Abstract: A method of cementing a production casing in a borehole having a surface casing therein wherein cement is pumped down through the production casing thereby cementing the production casing into the borehole and the surface casing. Prior to pumping a special production casing section carrying a tubular expandable resilient bladder is installed in the production casing. The bladder has flanges at either end and slots passing through the flanges. The bladder has an internal thread at one end which mates with an external thread on the casing section thereby anchoring the bladder. The other end of the bladder is free. When installed there is clearance between the bladder and the surrounding surface casing. This permits the bladder to expand upwardly when cement is pumped through and when there is a sufficient head of cement after pumping the bladder collapses and provides a good seal between the production casing section and the surface casing section.
