Abstract: Spirit levels including a horizontal bubble vial with improved bubble visibility for assisting user readability for leveling purposes. The improved bubble visibility is achieved by coloring a bubble's uppermost surface as perceived by a user.

Abstract: A semi-automatic sporting rifle is created by the modification of a fully automatic assault rifle Sa vz. 58. The semi-automatic rifle is constructed partly from original parts of the Sa vz. 58 assault rifle, i.e. bolt carrier, locking piece, striker, return mechanism, barrel, trigger, interrupter and left hand side striker catch, partly from modified parts of Sa vz. 58 assault rifle, i.e. bolt, trigger mechanism feather and safety catch and partly from newly manufactured parts, i.e. semi-automatic receiver with a narrowed magazine well for a single stack removable magazine with extended bridge, safety catch with one more groove on its lower left hand side, new sporting stock where grip part and butt-stock part form one unit and barrel extension permanently attached to the muzzle. Some parts of the Sa vz. 58 assault rifle are removed completely, i.e. muzzle thread protector, bayonet lug, original receiver, original stock, pistol grip, release, lever, trigger lever and right hand side striker catch.

Abstract: A spectacle has a body and two hinges. The body includes a frame, at least one glass and two temples. The temples are pivotally and respectively connected to the frame, and each temple has a hinge hole define through the temple. The hinges are held respectively in the hinge holes in the temples and are mounted between frame and the temples to respectively pivotally connect the temples to the frame. Each hinge has a base, a securing member and a connecting rod. The base has a bottom and an annular hooking groove defined around the base. The securing member is moveably mounted in the base and engages with the hinge hole in a corresponding one of the temples. The connecting rod is connected to the body and has a C-shaped hook detachably hooking around the hooking groove in the base.

Abstract: Railway container transhipment device for moving a container, wherein the device includes two underframes. Each underframe includes a crane unit, whereby the crane units are adapted to cooperate with one another. Each of the two crane units include a lower boom, and upper boom, a lower moving gear adapted to move the lower boom, an upper moving gear adapted to move the upper boom, and a lifting element arranged on the upper boom. An axial moving unit connects the two underframes and is adapted to adjust a distance between the two underframes. When the two crane units move the container, the railway container transhipment device is capable of adjusting an angle of movement of each of the two crane units which is proportional to the distance between the two underframes. This abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
