摘要:
A stabilized aqueous composition capable of producing or, in the presence of saliva or other humoral fluid, leading to the production of antimicrobially effective concentrations of hypothiocyanite ions (OSCN-) are herein described. The composition contains an oxidoreductase enzyme and its specific substrate, for the purpose of producing hydrogen peroxide of at least the minimum effective concentration, and in addition, catalase for the destruction of hydrogen peroxide to prevent premature oxidoreductase enzyme decomposition. Optionally, a peroxidase enzyme may be included to act upon the aforementioned hydrogen peroxide, thereby oxidizing thiocyanate ions to produce the antimicrobial concentrations of hypothiocyanite ions (OSCN-).
摘要:
An internal combustion engine comprises a piston (2) arranged to move reciprocally in a predetermined direction relative to an engine block (3). A drive shaft (54) is mounted in the engine block (3) and arranged to be driven by the piston (2) in rotational motion about a first axis perpendicular to the direction of motion of the piston (2). Rotational motion of the drive shaft (54) is transferred to a first shaft (80) that is mounted in the engine block (3) parallel to the drive shaft (54). Rotational motion of the first shaft (80) is then transferred to a second shaft (92) such that the engine produces a rotational output about an output axis that is parallel to the direction of reciprocal motion of the piston (2).
摘要:
A high speed motorized water ski (10) has a hull (16) having a bow (18), a stern (20) and a deck (22) sized for accommodating a standing rider (12). A jet pump (100) is mounted in the stern (18) for discharging a propelling stream of water outwardly from the stern (18) in a direction generally parallel to a longitudinal axis (144) of the hull (16). A motor (108) is mounted within the hull (16) for driving the jet pump (100). The standing rider controls the speed of the motorized water ski (10) by means of an arm pole (26) having one end attached to the hull (16) near the bow (18). A hand grip (132) is attached to the other end of the arm pole (26) for enabling the standing rider to control motor speed and for providing stabilization to the standing rider's stance on the deck (22). The motor (108), jet pump (100) and other components of the motorized water ski (10) are mounted in the hull (16) to define a center of gravity so that when a rider of average weight stands on the deck (22), the composite center of gravity (120) of the motorized water ski (10) and rider (12) is beneath the deck (22) in order to enable the standing rider (12) to turn the motorized water ski (10) solely by a shift in rider stance on the deck (22).

摘要:
The invention is an animal chew which contains one or more enzymes and substrates for the purpose of generating antimicrobial compounds upon contact with an animal's saliva. The animal chew, made of rawhide, biscuit or dried animal food is provided with an oxidoreductase enzyme and substrate, such as, for example, glucose oxidase and glucose, which produces hydrogen peroxide upon being chewed. A catalase may be provided to stabilize the system and prevent premature activation of the enzyme/substrate system. A peroxidase and halide or pseudohalide ion combination may be provided to enhance the antimicrobial effect of the invention.
摘要:
A fuel tank assembly is formed to fit within a personal watercraft hull that includes a cavity therein having curved sidewalls. A main fuel tank is formed as an elongate container that has a front section, a rear section and a central section. The central section is formed to have elasticity so that it can deform to conform to a sidewall portion of the cavity and exert an elastic force on the cavity sidewall sufficient to retain the main fuel tank inside the cavity.
