Title: Composite retaining wall
Inventor: EGAN PHILIP D
IPC: E02D29/02
Filed: 1998-01-06
Abstract: A retaining wall (10) having a height of greater than ten feet which includes a lower section of inextensible reinforcements (28a-e) and an upper section of extensible reinforcements (32-h). By the use of inextensible reinforcements in place of extensible reinforcements in a lower portion of a wall having a height greater than ten feet, the lower portion of the wall will tend to distribute the stresses of soil compaction and require less quality control assurance during construction. Further, by the use of extensible reinforcements in the upper section of a retaining wall having a height greater than ten feet, the extensible reinforcements will maintain the retaining wall in place and have significantly improved corrosion resistance over inextensible metal reinforcements.
Patent CA-2248484-A1 (CA)
Inventor: WALKER LLOYD L
IPC: F04B47/02
Filed: 1998-09-28
Abstract: The invention provides a back spin swivelling device for progressive cavity pump for pulling drive strings under torque. The device of the invention is particularly suited for use with progressive cavity pumps (PCP), and for the release of torque in a drive string through "back spin". The device comprises a housing having an opening at a bottom end adapted to receive a rotatable shaft and having means for attachment to an external support at a top end; said rotatable shaft being partially housed within the housing and projecting from the bottom end of the housing, the shaft having at its bottom end means for attachment to a polish rod which may be attached to a drive string; and means for mounting the shaft rotatably within the housing. The shaft and the means for attachment to the polish rod are substantially symmetrical about their common axis of rotation, and provide no point of articulation between the shaft and the polish rod. In a preferred embodiment, the device includes shock absorbing means for damping longitudinal displacements of the shaft. The symmetrical design of the rotating parts and the linear attachment of the shaft to the polish rod greatly improve the safety of the device in comparison with rod pulling devices of the prior art, avoiding equipment failure and possible injury due to flying apart of the device under the influence of "wobble" at high angular velocities.

Title: Liquid-cooled in-line fuel pump
Inventor: ROCHE RONALD H
IPC: F02M37/00
Filed: 1998-10-14
Abstract: A fuel system for a fuel injected internal combustion engine has a liquid-cooled fuel pump which draws fuel from a liquid-vapor separator and delivers it under pressure to the engine at a rate higher than that necessary to operate the engine. Preferably, a fuel pressure regulator downstream of the fuel pump and adjacent the engine bypasses excess fuel to a return fuel chamber in communication with the liquid-cooled fuel pump to cool the return fuel before it is returned to the liquid-vapor separator. Reducing the temperature of the returned fuel before it is discharged into the liquid-vapor separator reduces the generation of vapor in the liquid-vapor separator thereby enabling use of a smaller, less expensive vapor separator. Reducing the amount of fuel vapor in the system is desirable because the fuel vapor can decrease the efficiency and life of the fuel pump and is environmentally hazardous.

Patent CA-2271473-A1 (CA)
Title: Optical transparency having a diffuse antireflection coating and process for making it
Inventor: SARKAR ARNAB
IPC: G02B1/11
Filed: 1997-11-12
Abstract: A coated transparency, and method for making it, is disclosed, the transparency having a multi-layer antireflection coating that provides high transmittance with low specular reflectance, yet that also provides reduced visibility of surface defects. The coating includes alternating layers of polymerized silicon dioxide and polymerized titanium dioxide on a transparent substrate, with at least one of the layers incorporating discrete particles having a refractive index different from that of surrounding polymer. This provides the coating with a diffuse reflectance that is comparable to, or larger than, its specular reflectance, yet that still is negligible when compared to the coating's transmittance. The diffuse reflectance creates a loss of contrast for any reflected image or glare, thus masking any surface defects and providing a comfortable visual appearance. The successive layers of the antireflection coating are deposited on the substrate by applying separate solutions of an alkoxide, and alcohol, and water, and by curing the layer at an elevated temperature before the next succeeding layer is applied.
