Title: Grout packer
Inventor: REID LESLIE C
IPC: E02B17/00
Filed: 1990-05-04
Granted: 1994-07-26
Abstract: Abstract Of The Disclosure An inflatable grout packer includes a housing having an inner bore.  An annular inflatable bladder is received in the inner bore of the housing.  The bladder has an inflation cavity defined therein for containing an inflation fluid. The bladder has first and second axial ends and has radially inner and outer walls.  The bladder provides a seal between the housing and an elongated cylindrical member, typically a piling, received through the bladder.  First and second end rings are sealingly bonded to the first and second ends of the bladder and also sealingly attach to the housing so that a backup seal is thereby provided against leakage of infla-tion fluid through the radially outer wall of the bladder. An inflation coupling is attached to the radially outer wall.

Patent CA-2029756-C (CA)
Inventor: SURY KOHUR N
IPC: B03B9/02
Filed: 1990-11-13
Granted: 1998-09-22
Abstract: A process is disclosed for the removal of hydrocarbons such as bitumen or heavy fuel oil from hydrocarbon contaminated sludge, or particulate solid material or the like non-homogenous material after appropriate conditioning, such as by ball milling, with the conditioned material being aerated and then fed substantially tangentially into a substantially vertical cyclonic separator vessel to cause the hydrocarbons to which air bubbles have become attached to tend to float as a froth to the top of the vessel, with the remaining solids sinking to the bottom of the vessel.  The hydrocarbon containing froth is then removed from the top of the vessel, and the remaining solids removed from the bottom of the vessel.  This pneumatic flotation process obviates the need to add chemicals such as wetting agents or promoters.

Title: High performance washing process for vertical axis automatic washer
Inventor: CUR NIHAT OMER
IPC: D06F33/37
Filed: 1990-12-20
Granted: 2001-10-30
Abstract: A method for laudering a textile wash load is provided for use in a vertical axis washing machine in which a concentrated detergent solution is continuously applied to a spinning wash load for a predetermined time period to thoroughly wet the clothes load. The initial charge of detergent is thoroughly mixed with the detergent in a recirculation step before being applied to the clothes load. The concentrated wash liquid is incrementally applied to the spinning clothes load until a sufficient amount of wash liquid is detected as having been introduced to the wash zone. That amount of wash liquid is then recirculated and reapplied to the clothes load for a predetermined length of time. After the time period, additional water is added to the solution to dilute it to a normal concentration and then mechanical agitation and rinsing steps are conducted to complete the wash cycle.

Inventor: LAAPOTTI JORMA
IPC: D21F3/02
Filed: 1991-06-04
Granted: 1995-12-12
Abstract: Method and device for intensifying the dewatering of a web in a paper machine press section having a compact roll combination and a separate press.  The web is pressed in press nips formed by a compact roll combination.  Thereafter, the web is transferred on a paper guide roll onto the outer face of the press felt of the separate press, on which felt the web is transferred into the nip of the separate press.  The web runs over the lower sector of the paper guide roll and before the web is transferred into the nip of the separate press,  the web as well as the press felt of the separate press are heated by means of heating devices.  By means of these devices, the temperature levels both of the web and of the outer face of the press felt of the separate nip which felt reaches contact with  the web  are  raised  so  that  the  dewatering  is substantially intensified in the separate nip.

Title: Recovery of nickel from uranium containing ore
Inventor: LAM EDMOND K
IPC: C22B3/44
Filed: 1992-01-14
Granted: 1998-04-28
Abstract: Nickel is found in substantial quantities in some uranium-containing ores.  Recovery of uranium from such ores by the known acid leaching process includes a solvent extraction stage that leaves an aqueous raffinate containing nickel, together with other components including iron, arsenic, radium 226 and uranium.  Attempts have been made to recover nickel from this raffinate but have not been successful because the costs of recovery are so high that the process is uneconomic or because the nickel obtained is contaminated with radium 226 and uranium to such a degree that the nickel is unacceptable.  The present invention provides a process for obtaining from the raffinate a solution of a nickel salt that is not unacceptably contaminated with radium 226 and uranium.  The process is economic and in a preferred embodiment uses only air, lime and a barium salt, preferably barium chloride, as reagents.  If cobalt is also present in the ore it is recovered with the nickel.

Title: Method for manufacture of pre-cheese and natural cheese
Inventor: NAUTH KAISER R
IPC: A23C19/028
Filed: 1993-01-13
Granted: 2003-06-17
Abstract: The present invention is directed to a process for manufacture of pre-cheese that is capable of being converted into natural cheese having total solids in excess of 55%. The process includes the steps of removing moisture, salts and lactose from skim milk by a membrane process to provide a retentate having between about 70% and about 83% moisture, between about 0.7% and about 2.5% salts and less than about 1.8% lactose.        Cultures capable of metabolizing lactose to lactic acid are added to the retentate and the retentate is fermented until the lactose of the retentate has bean substantially converted to lactic acid. Sufficient lactose is provided to reduce the pH of the retentate to within the range of about 4.8 to about 5.6. The fermented retentate is then subjected to centrifugation to provide a concentrate having from about 30% to about 50% total solids. The concentrate is combined with a milk clotting enzyme, fat, salt and a mixed fermentate comprising a high digest casein fermentate, a lipolytic fermentate, a protease, a lipase and a proteolytic micrococcus to provide a cheese base. The cheese base is then fermented-to-provide a pre-cheese suitable for use in the manufacture of process cheese. In a further embodiment of the present invention, the pre-cheese is texturized to provide a natural cheese by working the pre-cheese in a mechanical mixer.

Title: Reinforcing block for excavation work and method of construction thereof
Inventor: TATEYAMA MASARU
IPC: E02D3/12
Filed: 1993-01-28
Granted: 2003-05-20
Abstract: A novel method to construct a reinforcing block in an embankment is provided, wherein a core rod to which a protrusion is molded on the tip, is preset inside a hollow rotating shaft with drilling and agitating blades affixed around its circumference, but with the protrusion on the core rod exposed at the front of the shaft. This drilling and agitating shaft rotates and bores into the earth while simultaneously mixing the soil so agitated with a fixing agent; then at a specified depth, the rotating shaft is withdrawn leaving the core rod to remain anchored in the soil while the fixing agent continues to discharge from the end of the hollow rod; and when the hollow rod is completely removed, a reinforcing block is intact within the soil and the tail end of the core rod exposed on the surface of the banking is directly or indirectly affixed to this surface.      Alternatively a core rod with no protrusion can be inserted into the hollow rotating shaft which is first drilled into the embankment, such that the nose end of the said core rod is anchored into unagitated soil. In either case the reinforcing block so formed is comprised of an outer concentric tube of agitated soil mixed with a fixing agent molded around an inner concentric tube of reinforcing fixing agent molded around a core rod, and wherein the nose tip of the core penetrates into the unagitated soil beyond the end of the concentric reinforcing layers.
