A crash helmet includes a helmet body, a face mask, and a binding device for attaching the face mask to the helmet body. Thus, the face mask is mounted on and removed from the helmet body easily and rapidly by operation of the binding device, so that the crash helmet is assembled and disassembled easily and rapidly, thereby facilitating a user mounting and dismantling the crash helmet. In addition, the face mask is mounted on the helmet body by the binding device without needing a metallic spring to prevent the crash helmet from being inoperative during a long-term utilization, thereby enhancing the lifetime of the crash helmet.

An x-ray device is provided. The x-ray device includes a C-arm that may be rotatably mounted on a robotic arm. A radiation source and a radiation detector may be arranged on the C-arm. The interior of the C-arm, which is hollow at least in sections, is accessible from at least one access side to allow at least a part of the electronic components used to operate the radiation source and the radiation detector to be integrated in the interior of the arm.

A removable security bar apparatus for preventing ingress through a building opening such as a window or door. The apparatus includes a grille and latch mechanism permitting quick removal of the grille from the building opening in the event of an emergency. The grille is held in place across the opening by a stop member which secures one side of the grille structure to the opening and a latch mechanism. The latch mechanism includes at least one removable rod positioned through a wall mounted bracket and into a fixed rod secured to the grille thereby securing the grille over the building opening. The grille is rapidly removed by sliding the at least one removable rod away from the fixed rod and bracket allowing the grille to be gripped and moved away from the opening.

Disclosed are photoimageable compositions having improved stripping properties as well as methods for manufacturing printed wiring boards using such photoimageable compositions.

Low-cost, single-use, disposable foot coverings and a method of using them to facilitate the protection of the feet of individuals who remove their shoes and would otherwise have to walk barefoot are disclosed. Assemblages of a number of such foot coverings (e.g., in the form of a continuous serrated roll of them) and methods of making the assemblages are also disclosed. The foot coverings may be particularly useful at security stations (e.g., in airports) where individuals must remove their shoes for inspection and then walk barefoot until their shoes are returned to them.

A carpet kicker with a wing panel including a main body and a first spreading unit for spreading the carpet. The first spreading unit is attached to the bottom of the main body. Both sides of the first spreading unit are provided with a rail for connecting with a wing panel in place. The wing panel includes an elongated portion that is at least two times as long as the width of the first spreading unit. A U-shaped groove opposing to both sides of the first spreading unit is formed at the internal side of the center of the elongated portion. Both sides of the U-shaped groove are provided with a rail recess corresponding to the rail at both sides of the first spreading unit. A receiving chamber with an opening directed downward is formed at both sides of the U-shaped groove, respectively. Moreover, a needle unit for spreading the carpet is disposed within each of the receiving chambers such that a second spreading unit and a third spreading unit are symmetrically positioned at both sides of the U-shaped groove of the elongated portion. In this way, the area for simultaneously spreading the carpet is multiplied.

The present invention provides a process for isolating vascular endothelial cells from embryoid bodies differentiated from embryonic stem cells, which comprises: (a) treating embryoid bodies differentiated from embryonic stem cells with 0.005-0.015% trypsin and 0.05-0.15 mM ethylenediaminetetraacetate (EDTA) to obtain vascular endothelial cell clusters; and (b) treating the vascular endothelial cell clusters with 0.1-0.5% trypsin and 0.5-2 mM EDTA so as to separate the vascular endothelial cell clusters into single cells.
