A device for blowing air by a nozzle assembly includes a base seat for generating an air stream to supply air flow and a nozzle assembly supported by the base seat and comprising a slot-shaped opening for blowing air. An airflow passage is connected between the base seat and the nozzle assembly. An intake end of the airflow passage is opened on the outer surface of the base seat, and an output end is connected to the nozzle assembly by a pivot component. An intake end of the nozzle assembly is connected to an output end of the base seat by the pivot component. An impeller and electric motor for driving the impeller to rotate are provided within the base seat. The nozzle assembly is rotatably fixed on the base seat by the pivot component.

An axle spindle nut assembly secures a wheel end assembly on an axle spindle. The wheel end assembly includes outboard and inboard outboard bearings that are immovably mounted on the axle spindle, and a wheel hub which is rotatably mounting on the bearings. The spindle nut assembly includes a nut that threads onto an outboard end of the axle spindle, and is tightened against the outboard bearing to a selected torque level. The nut includes an outboard surface that is formed with a plurality of features. A washer is formed with a tab that engages a keyway of the axle spindle outboardly of the nut, and with a plurality of mating features that mechanically engage the features formed in the outboard surface of the nut to prevent substantial rotation of the nut after the nut has been tightened to the selected torque level.

An improved rod connector assembly and method for mechanically fastening two rods together. Generally planar mating surfaces of a first rod assembly and a second rod assembly are compressively coupled by a rod union. The compressive load by the rod union is derived from a tapered surface that provides an interference fit to a corresponding tapered surface on the first rod assembly. Clearance diameters provided within the rod union accommodate axial misalignment of the first rod assembly and the second rod assembly. The second rod assembly includes an adjustable rod adapter to provide coupling to rods of various lengths. The first rod assembly includes an internal cavity to receive a portion of the second rod that may protrude from the adjustable rod adapter. Shaped mating surfaces of the rod adapters are received in a corresponding shaped cavity of the union to prevent rotation of the adapters.

The present invention relates to an interspine cage inserting device, and more particularly, to an interspine cage inserting device capable of stably and easily inserting a cage inserted between spines.Disclosed is an interspine cage inserting device. The interspine cage inserting device includes: a support unit including an internal hollow portion and accommodating an internal rod coupled with a cage inserted between spines; a first moving unit formed on one side of the support unit and pushing the cage in connection with one side of the cage; a second moving unit formed on the other side of the support unit and connected with the other side of the cage to be connected to move backward when the first moving unit moves forward; and an adjustment unit connected to the support unit so as to adjust a rotational amount of the cage by adjusting movement of the first moving unit and the second moving unit.

An electrical connector system including first and second electrical connector members mated to one another to form a sealed connection in order to protect electrically-conductive components against the infiltration of moisture. The first connector member includes a socket with a first annular ridge at its tip, while a second annular ridge is formed within the socket at its base. An electrically-conductive pin is housed within the first connector member and extends into the interior of the socket. The second connector member includes a plug. An electrically-conductive socket, mated to the pin, is housed within the plug. When the plug of the second connector member is mated with the socket of the first connector member, the tip of the plug contacts the annular ridge at the base of the socket, which is deformed so as to form a water-tight seal between the tip of the plug and the base of the socket. Likewise, the annular ridge at the tip of the socket contacts the base of the recess and is deformed so as to form another water-tight seal between the tip of the socket and the base of the recess.

A gas supplying mechanism in a gas powered toy gun comprises a gas passage for supplying gas to be used for shooting a sham bullet put in a bullet holding chamber, a movable valve for controlling the gas passage to be open for supplying the gas and closed for ceasing to supply the gas selectively, a hammer operative selectively to rotate at high speed to a first position from a second position in response to a triggering operation performed for shooting the sham bullet and to rotate at low speed to the first position from the second position independently of the triggering operation, a positioning member provided to come into contact with the hammer put in the first position for positioning the same, and a movable linking member for moving in a first manner corresponding to the high speed rotation of the hammer to push the movable valve to move for shifting the gas passage to be open when the hammer rotates at the high speed and for moving in a second manner corresponding to the low speed rotation of the hammer to cause the movable valve to keep the gas passage closed without pushing the movable valve to move when the hammer rotates at the low speed.

If the a rotational speed difference (Ne−Nt) between an engine speed (Ne) and a turbine speed (Nt) when it is determined that a lock-up ON condition (OFF→ON) is satisfied is large, the lock-up clutch is not engaged but torque reduction control is executed to reduce the engine speed (Ne), thus reducing the rotational speed difference (Ne−Nt) (steps ST13 and ST14). Then, once the rotational speed difference (Ne−Nt) has been reduced to the target rotational speed difference (Nslp), the lock-up clutch is engaged (steps ST15 and ST16). In this manner, excessive heating of the friction material of the lock-up clutch is suppressed which increases the longevity of the friction material.

Disclosed is a single wedge wrench including two jaws, one of which has a zigzag gripping surface. The wrench further includes a wedge having a zigzag gripping surface. The wedge is mounted on an inner surface of the other one of the two jaws by means of a joint member, being slidable along the inner surface. The wrench disclosed can be used for bolts or nuts with various types and sizes, and an operation can be performed as long as a handle of the wrench is returned. The wrench can be manufactured with a simple process in a production line.

Systems for inhibiting installation of emergency escape slides behind bustles (or other covers) when removable safety pins (or similar objects) remain intact are addressed. Versions of the systems mechanically interfere with installation of the bustles as long as the safety pins remain in place. Only when all safety pins are removed can the mechanical impediment be detached (or moved sufficiently) to permit installation of the bustles.
