Title: Cylinder combustion gas leakage testing
Inventor: HOBAN PATRICK JOSEPH
IPC: G01M3/02
Filed: 1995-11-16
Abstract: A  leakage  tester  for  identifying  defective piston assemblies  in a diesel engine  includes an adapter fitting for connection to a compression relief valve port on a selected diesel engine cylinder, a fixed length of air conduit having a preselected inside diameter connected at one end to the adapter fitting, and an orifice meter having an air inlet and an air outlet.  The orifice meter includes first and second  pressure  gauges  for  measuring  air  inlet pressure and air outlet pressure, respectively, the air conduit having another end connected to the air outlet.   In use,  the tester is connected to the compression relief valve port and the air inlet of the orifice meter is connected to a source of pressurized air.  With the engine advanced to position the piston in  the  selected cylinder at  top dead  center,  a preselected pressure is applied to the orifice meter.          Cylinder leakage is then determined directly from the pressure reading on the second pressure gauge.   A pressure regulator coupled between the  source of pressurized air and the air inlet on the orifice meter maintains a preselected pressure at the air inlet.

Title: Production of dicarboxylic acids
Inventor: HARVIE JAMES LUMDSDEN
IPC: C07C51/09
Filed: 1994-06-29
Abstract: Dicarboxylic acids or esters thereof are recovered from solid phase polyester materials, such as post-consumer products and factory scrap, by subjecting the polyester to at least two hydrolysis stages in at least the first of which the amount of water used is substantially less than needed to effect total conversion of the polyester to the dicarboxilic acid. Also the diol content is controlled in the course of carrying out the hydrolysis. The hydrolysis reactions may be preceded by reaction of the polyester with a diol, the resulting depolymerisation products then being hydrolysed.

Abstract: Sont décrits un système et un procédé acoustiques destinés à éloigner les mammifères marins d'une zone aquatique. Plusieurs transducteurs (10, 12, 14, 16) sont répartis sous la surface de l'eau. Ils y émettent, en séquence, des sons à haute fréquence. La puissance de ces sons, faible au début, augmente progressivement ou par paliers successifs, atteignant un niveau si élevé qu'il dépasse le seuil de douleur des mammifères à écarter. Ainsi, ceux-ci s'éloignent progressivement de la zone, sans toutefois souffrir de pertes définitives de l'audition.
Patent CA-2166144-A1 (CA)
Inventor: DALLAIRE RAYMOND
IPC: E06B7/14
Filed: 1995-12-27
Abstract: A drainage system for horizontally sliding closures is disclosed, especially horizontally sliding closures having a solid sill such as is typical with patio doors and the like. The drainage system includes a valve assembly having a top wall, opposed end walls and a side wall that defines a drainage aperture. The drainage aperture is normally closed by a hinged flap which permits water to drain through the valve assembly but inhibits the infiltration of outside air. The valve assembly is mounted over a drainage slot cut through the fixed rail. To ensure most efficient drainage performance, the fixed rail must be vented. This is preferably accomplished by replacing the usual end caps for the fixed rail with slotted end caps which maintain the internal air pressure in the fixed rail with substantially atmospheric pressure. The advantage is a simple, inexpensive very effective drainage system which is suitable for new product and the retrofit of installed doors and/or windows.

Abstract: A disguised broadband antenna system for use with a broadcast radio receiver and communications apparatus in a vehicle wherein the antenna system comprises a standard broadcast antenna mounted to the vehicle by means of a base, a distributed matching network for coupling the antenna to the broadcast receiver and the communications equipment in the vehicle and a broadcast coupler connected between the matching network and the broadcast receiver and communications equipment for providing isolation between the broadcast receiver and communications equipment.  The distributed nature of the matching network provides the broadband frequency response required while at the same time providing the highest Q factor available in a limited size and spreads any power dissipation over a relatively larger area.  A series reactive element is connected electrically to the antenna through the base to cause the antenna to operate closer to resonance through the broadband frequency range of interest. The distributed matching network comprises at least one transmission line connected to the series reactive element and matching elements operatively associated with the transmission line to provide characteristics of the matching network resulting in broad bandwidth, low standing wave ratio and low power loss operation of the broadcast receiver and the communications equipment from the antenna so that the antenna and base maintain the outer visible appearance of a standard vehicle antenna.

Inventor: ZHOU ZHIHONG
IPC: E21B33/138
Filed: 1996-11-28
Abstract: A method is provided for blocking high permeability channels in subterranean geological formations, using swelling clay. A slurry is prepared by mixing swelling clay, such as bentonite, into an aqueous solution containing the salt of certain cations, which inhibit clay swelling. The cations K~, Ca2~ and Mg2~, among others, are inhibitive of clay swelling. The clay slurry is introduced into a geological formation, where it preferentialy enters channels of high permeability. There the slurry is contacted by NaCl brine solution present in natural or injected drive fluids, and the inhibitive cations bound to the clay particles are replaced by Na~ ions, which attract water molecules and promote clay swelling. The Na~ - clay swells to up to 10 times its original volume, causing the shiny to acquire a gel- like consistency. The clay gel so formed is capable of blocking the flow of water, and can resist pressure of up to 500 kPa per meter.
