Patent CA-2118205-A1 (CA)
Title: High efficiency gas furnace
Inventor: KRAEMER WILLIAM E
IPC: F24C3/00
Filed: 1994-10-14
Abstract: A high efficiency gas furnace utilizes a unique pre-mix design in combination with a pressurized/high velocity combustion process. The combustion process occurs in a combustion chamber and the high temperature high velocity products of combustion follow a circuitous route from the combustion chamber through finned tubular conduits to an exhaust. Heat from the high temperature high velocity products is transferred to the finned tubular conduits. An air blower assembly forces air across the finned tubular conduits and the combustion chamber to remove the heat from the finned tubular conduits and transfers this heat to a building or an enclosed portion thereof.

Title: Method and device for biochemical sensing
Inventor: HOLM-KENNEDY JAMES W
IPC: G01N33/543
Filed: 1992-10-20
Abstract: A method and application for detecting and measuring the presence of a binding target material (64) employs a semiconductor device (50) having a receptor-covered surface (90) topgate (60), separated by a dielectric layer (58) from a substrate (56). Receptors (66) attached to this surface exhibit a chemical selectivity function. Binding occurs in a test solution (52), with charge associated with the target material (64) modulating at least one device characteristic. According to the present invention, measurement may occur under dry conditions, at a time and location different from when binding occurred, thus substantially eliminating problems associated with ionic shielding and reference electrodes, so prevalent with prior art wet measurement techniques. Preferably the device (50) includes backgate (62) to which a bias may be applied to restore the device's pre-binding characteristics. Measurement of the restorative backgate bias provides a signal indicating binding of the desired target material.

Abstract: A slider  is provided for connecting a  choker assembly including a choker rope having an end provided with a ferrule, to a winchline. The slider has a first winchline-receiving link in the form of a first elongated closed loop defining  a  first  elongated  opening  for  receiving  the winchline. The first link also has a longitudinal axis and a pair of opposite ends on the axis, one of the ends is substantially larger in section than the other one and has a curved bottom wall. This first link also has top and bottom   surfaces,   and   a   substantially   trapezoidal configuration when seen in side elevational view. The slider also has a second choker-rope receiving link in the form of a second elongated loop defining a second opening. This second link is provided with a longitudinal U-shaped slot leading from the second opening out of the second link through an end thereof. This U-shaped slot is sized for receiving the choker rope and has a first extremity within the second opening which defines a seat for the ferrule. The U-shaped slot has opposite side walls sized and shaped to prevent angular displacement of the choker rope within the slot with respect to the ferrule. The walls have edges that are slightly rounded and apertures for receiving a ferrule locking pin to prevent the ferrule from exiting the second link. The slider further has a third connection link in the form of a third closed loop defining a third opening. This third link passes through the first and second openings and connects the first and second links together.  When the slider is used, it is able to conform to any bearing surface while preventing overbending of the choker rope adjacent to the ferrule.

Filed: 1994-04-27
Abstract: ABSTRACT (A) A clad powdery or granular preparation of a medicinally active ingredient and (B) a powdery or granular ion exchanger such as a cation exchange resin are blended to prepare a solid preparation. The active ingredient includes .beta.-lactam antibiotics having a basic group. The clad powdery or granular preparation in-cludes not only coated preparation wherein the active ingredient or preparation is coated but also a variety of preparations in which the contact of the active ingredient with the ion exchanger is suppressed or inhibited.  Polymers such as a water-soluble polymer, an enteric polymer and so on can be used as the coating agent for the coated preparation.   The using amount of the ion exchanger is about 10 to 5,000 parts by weight per 100 parts by weight of the active ingredient.  Said solid preparation can remarkably decrease the unpleas-ant taste and odor of the active ingredient such as bitterness, being excellent in dissolution property and absorbability of the active ingredient.

Title: Crystal proteins of bacillus thuringiensis, genes encoding them, and hosts expressing them
Inventor: BROWN KIT L
IPC: C12N15/32
Filed: 1992-07-09
Abstract: Two genes encoding the predominant polypeptides of Bacillus thuringiensis) subsp. thompsoni cuboidal crystals were cloned in Escherichia coli and sequenced. The new class of crystal proteins have electrophoretic mobilities of 40 and 34 kilodaltons (kDa) with the deduced amino-acid sequences predicting molecular masses of 35,384 and 37,505 daltons, respectively. No statistically significant similarities were detected for the 40 kDa and 34 kDa crystal proteins to any other characterized Bacillus thuringiensis) crystal protein or to each other. A 100 MDa plasmid encodes both crystal protein genes, which appear to be part of an operon with the 40 kDa gene 64 nucleotides upstream of the 34 kDa gene. Both crystal proteins are synthesized in approximately the same amounts. Even though small, compared to other crystal proteins, the 34 kDa crystal protein has insecticidal activity against lepidopteran larvae (Manduca sexta).
