Patent number: 5965671Abstract: Modified resole and novolac type phenolic resins which are toughened by poly(alkylene oxide) are disclosed. The modified resole type phenolic resin is prepared by the following steps: mixing a poly(alkylene oxide) having a weight average molecular weight of 100,000.about.8,000,000 and phenol in a weight ratio of poly(alkylene oxide): phenol=1.5:1.about.1:1 at an elevated temperature to form a glutinous mixture; mixing the glutinous mixture with an acid catalyst to obtain a viscous mixture having a relatively low viscosity compared to the glutinous mixture; and mixing the viscose mixture with a resole type phenolic resin. The modified novolac type phenolic resin is prepared by directly mixing the glutinous mixture with a liquid novolac type phenolic resin. The amount of the poly(alkylene oxide) mixed is 2.about.10 wt % based on the phenolic resin.Type: GrantFiled: March 5, 1998Date of Patent: October 12, 1999Assignee: National Science CouncilInventors: Chen-Chi Martin Ma, Hew-Der Wu, Chih-Tsung Lee

Patent number: 5786342Abstract: Acemannan has been shown to be effective in treating a number of conditions where the principal mechanism of resolution or cure requires intervention by the patient's immune system. Acemannan has direct stimulatory effects on the immune system. Methods for treating cancer, viral diseases, respiratory and immune regulatory diseases, inflammations, infections and infestations by administering an acetylated mannan derivative, such as acemannan derived from aloe, are described. The method finds use in tissue cultures, animals and plants.Type: GrantFiled: June 5, 1995Date of Patent: July 28, 1998Assignee: Carrington Laboratories, Inc.Inventors: Robert H. Carpenter, Harley R. McDaniel, Bill H. McAnalley

Patent number: 5783605Abstract: Cancer cells are blocked from entering differentiation pathways because of abnormal methylation enzymes, which are responsible for keeping cancer cells in cycling state. Effective differentiation inducers are those capable of acting directly or indirectly to convert abnormal methylation enzymes into normal enzymes, thereby enabling cancer cells to undergo terminal differentiation. Differentiation employing inducer alone often can not reach completion because of the damage created by the inducer. Such damage can be prevented if differentiation is induced in the presence of helper inducers, which are basically inhibitors of the component enzymes of methylation. Thus, differentiation induced in the presence of helper inducers is more likely to reach completion. Therefore, helper inducers are essential components of differentiation therapy, not just merely to potentiate the activity of differentiation inducers.Type: GrantFiled: October 15, 1996Date of Patent: July 21, 1998Inventors: Sheng-Chu Kuo, Jau-Hong Lee

Patent number: 5777954Abstract: An air-bladder free hydrophone streamer for use in an aqueous environment and a method of manufacture thereof. The hydrophone streamer includes: (1) data acquisition equipment including data bus interconnecting a plurality of hydrophones, the data acquisition equipment having a specific gravity greater than that of an environmental fluid constituting the aqueous environment, (2) a jacket surrounding the data acquisition equipment, the jacket forming a void about the data acquisition equipment, the jacket having a specific gravity less than that of the environmental fluid and (3) a water-based fill fluid occupying the void, the jacket providing buoyancy for the data acquisition equipment to allow the hydrophone streamer to assume a near-neutral buoyancy with respect to the environmental fluid.Type: GrantFiled: February 14, 1997Date of Patent: July 7, 1998Assignee: Hydroscience TechnologiesInventor: John Stephen Hepp

Patent number: 5765892Abstract: The present invention provides an extension apparatus for use with a vehicle having a cargo-bed area with opposing first and second side walls, and a tailgate movable between a vertical orientation and a horizontal orientation. The extension apparatus comprises a rear panel, which has opposing first and second ends, pivotally couplable to the tailgate to pivot the rear panel between a side-board configuration and a cargo-bed extension configuration. A first side panel is pivotally coupled to the rear panel adjacent the first end, and a second side panel is pivotally coupled to the rear panel adjacent the second end. The extension apparatus further includes a side panel receiver securable to a selected one of the first or second side walls of the cargo-bed area to receive a portion of the selected one of the first or second side panels therein.Type: GrantFiled: October 5, 1995Date of Patent: June 16, 1998Inventor: James Roy Covington
