摘要:
The GapC plasmin binding protein genes of Streptococcus dysgalactiae (S. dysgalactiae), Streptococcus agalactiae (S. agalactiae), Streptococcus uberis (S. uberis), Streptococcus parauberis (S. parauberis), and Streptococcus iniae (S. iniae) are described, as well as the recombinant production of the GapC proteins therefrom. Also described is the use of the GapC proteins from those species in vaccine compositions to prevent or treat bacterial infections in general, and mastitis in particular.

A disk-like piezoelectric lighter with a safety lock includes a casing, a gas emitting nozzle, a piezoelectric unit, a sliding member and a safety lock. The safety lock comprises an arcuate resilient arm; a sliding cap having an cover portion, a pair of stands, a pair of branch arms, a lateral blocking stopper and a guiding slot; a safety button which comprises a base portion and a button portion and which is mounted slidably in the guiding slot in such a manner that the base portion comes into contact with the resilient arm to allow the resilient arm to be shifted from the locked position that the resilient arm is blocked up by the blocking stopper to the unlocked position that the blocking up is released to ignite the piezoelectric lighter.

A piezoelectric lighter of model R with a safety device includes a casing, a storage, a gas emitting nozzle, a piezoelectric unit, a fixed cover, and a safety device. The safety device comprises a blocking stopper; an ignition cap having a cover, a guiding groove and a guiding aperture; a safety button comprising a button portion, a locking arm, a spring and a guiding retaining shaft that is movably arranged in the guiding aperture to push by the spring force the safety button right to form a locked position that the blocking stopper is located in the traveling way of the locking arm; only if the button portion is pushed left, the locking arm is moved away from the stopper to form an unlocked position that the blocking up is released to ignite the piezoelectric lighter.
摘要:
The recombinant production of Gap4, a chimeric GapC plasmin binding protein comprising the entire amino acid sequence of the Streptococcus dysgalactiae GapC protein in addition to unique amino acid sequences from the Streptococcus parauberis and Streptococcus agalactiae GapC proteins, is described. Also described is the use of Gap4 chimeric GapC protein in vaccine compositions to prevent or treat streptococcal infections in general and mastitis in particular.

摘要:
An actuator which comprises a pair of elongated elastomer tubes (6,16), sealed by respective members (18, 20, 22, 24) at each end, the members at the one end (18, 20) being fixed and the members at the opposite end (22, 24) sliding in guides (34, 36), the sliding ends of the first and second tubes being connected by a chain (26) and sprocket (10) to convert linear motion to rotary motion.
摘要:
The device comprises an elongated elastomer tube, sealed tightly by clamps at each end against disk shaped end pieces, the one end disk fixed and the other sliding, axially to the other disk, on restraining rods. An orifice in the fixed disk permits the injection of pneumatic pressure causing the expansion of the elastomer tube. Surrounding the elastomer tube is a restraining tube of woven fabric or other material which will not expand radially. The second tube is also affixed to each end disk by the clamps and has sufficient length to reach between the two disks when the disks are at their farthest distance from each other. When the disks are not fully distanced from each other, the outer tube crumples axially but not radially. Action commences when the disks are closest to each other. Controlled pneumatic pressure injected through the orifice causes expansion of the elastomer tube. The outer restraining tube causes all force to be directed to move the sliding disk away from the fixed disk on the guiding mechanism, thus creating an axial force.
摘要:
A mechanism for varying the stroke length of an internal combustion engine during each cycle of operation includes a gear set with a first gear non-rotatably mounted to the engine block and a second gear having teeth formed on an inner surface thereof meshing with the first gear to achieve a uniform mechanical crank arm and a variable cam arm for producing a varying length of piston reciprocation throughout the overall stroke cycle of the engine. The orientation of the crank arm and the cam arm relative to the axis of piston reciprocation is selected for causing the crank arm and the cam arm to cooperatively produce a positive torque on the crankshaft at the top dead center position of the piston. The gear set is also selectively configured and dimensioned to achieve a predetermined ratio of the length of the cam arm to the length of the crank arm.
