Abstract: Liquid nanoscale particle precursor materials for generating nanoscale particles include at least one high volatility carrier and a second component. A nanoscale particle generating device generates nanoscale particles by passing a liquid nanoscale particle precursor material through a flow passage heated to convert the carrier into a vapor and the second component into nanoscale particles. The nanoscale particles preferably consist essentially of the second component and can consist essentially of dry, solid particles. The particle generator can be incorporated in a hand held inhaler, and can be delivered to a targeted portion of the lung using the inhaler. Composite controlled release particles of micron or nanoscale size can be produced by flowing a solution of medicament, control release agent and carrier liquid through a capillary heater.

Abstract: A latch unit having a cylindrical housing consisting of two half portions for containing a latch bolt, a moving member to retreat the latch bolt and a recovering member to push the latch bolt forward to an original position in which the latch bolt extends out of the housing.

Abstract: A locking device for an auxiliary lock comprising a safety button able to be pressed in and a rotating ring to be rotated to actuate the dead lock to be extended for locking the lock.

Abstract: A tubular door lock for low safety comprising two knobs provided with a tubular shaft combined with a bearing plate, the tubular shaft having a hook and a projection to combine with an actuating plate, a square rod provided to fit in the actuating plates at both ends to enable the two knobs--the inner and the outer one--to move together at the same time.

Abstract: A locking device for an auxiliary lock comprising a rotatable ring, able to be rotated at the outside of a lock to turn an actuating wheel 90.degree., said actuating wheel having an 8-shaped opening for an actuating plate of the dead bolt to pass through so that the actuating plate can be turned 90.degree. to extend the dead bolt latch out to lock a door.

Abstract: A tubular door lock having a kind of structure, wherein locking the lock by an inner knob is accomplished by first pressing and subsequent rotating of said knob, and unlocking by said knob can be done only be rotating of said knob.

Abstract: A locking device for an auxiliary lock comprising a rotatable ring provided with inner teeth around the inner peripheral surface and a traditional lock additionally provided with a lateral hole to fit a spring and a steel ball pushed by the spring therein, the ball extending a little out of the lateral hole to engage with the inner teeth in the rotatable ring, the inner teeth being able to be felt surely to slide over the ball when the rotatable ring is rotated.

Abstract: An inner bearing plate unit of easy assembling for a lock comprising an inner bearing plate, an inner plate and a position plate, to be assembled with an outer bearing plate, said inner bearing plate and said inner plate being assembled together tightly sandwiching the position plate rotatable therein, said position plate having two opposite gourd-shaped holes for two connecting posts of the outer bearing plate to pass through, and the heads of screws mounted at the ends of said posts being able to be made to be positioned through the large diameter sections of said gourd-shaped holes and to stick in the two opposite holes in the inner bearing plate, thus assembling the inner bearing plate unit with the outer bearing plate.

Abstract: A king of handle lock with improved engagement and linking-up comprises a base with a handle. The base contains a base plate, driving members, a face plate, an inside knob, and a press handle. By the inner moving tube engaged with the driving plate of latch, the inside knob and outside knob will alone drive the inner moving tube.

Abstract: A cylindrical lock is locked, the "locked" position is kept from the outside knob, which can not be revolved to open the door, but the inside knob is turnable to open the door after the lock is locked.

Abstract: A structure for controlling the dead bolt used in an electronic lock comprising a turning button at the inside of a door for locking or unlocking the lock and a structure at the outside of a door to unlock either with a coded number card or a key.

Abstract: A tubular latch housing having a plurality of projections on its outer periphery for keeping a ring fitted around said housing between said projections and a face plate combined at the outer end of said housing so that said housing can rotate to adjust its position for combining with a lock set even after said housing is mounted in a door.

Abstract: A tubular door lock (1) has an actuating plate member (4) of metal formed by pressing and provided with a square shaft hole (42) and four square projections (43) around the square shaft hole to fit in a round opening (22, 32) of either of two assembling plates (2, 3) between which the actuating plate (4) is disposed when assembled. The actuating plate is rotated by rotation of the square shaft so that cams (44) thereon engage teeth (13) on bolt plate (11) to retract the bolt (12).

Abstract: A locking device for an auxiliary lock comprising a rotatable ring and a base. The ring is fitted around the auxiliary lock and combined with the base. Then they are mounted in the door to let a large part of the rotatable ring be exposed outside the door, and rotating the ring can cause the dead bolt of the auxiliary lock to extend out locking the lock.

Abstract: A united opening device for a double lock comprising a cam disc respectively on the shafts of a main lock and an auxiliary lock, and an intermediate plate which interacts with the two cam discs, able to unlock the auxiliary lock at the same time when the main lock is rotated to unlock after both locks have been locked.

Abstract: A cylindrical lock comprising two limit plates, whose movement can control the outside knob and the inside knob both unturnable or the outside knob unturnable but the inside knob turnable.

Abstract: An auxiliary lock with an extensible device comprising a push button which can function to make a case extend or shrink so that the auxiliary lock can be changed in the short or the long size.

Abstract: A tubular door lock making use of two pairs of motive teeth in a pulling plate for a two-tooth gear to selectively mesh with for an motive action. The gear is confined within a hole cut in a moving shell, which can move outside along the assembling plates and be fixed to keep a hole in it to exactly face against a hole in the assembling plates so as to enable the foot post of the door lock to penetrate through the both holes, whether this lock is adjusted in the short or in the long size.
