摘要： Electrically conductive metal is melted, preferably by a flame, and is sprayed onto a freshly exposed, pitted surface of a concrete member having iron embedded therein. The sprayed metal, when cooled, forms a metal cover on and interlocked with at least part of the newly exposed surface. The cover and the embedded iron are preferably joined in an electric circuit affording a direct current electromotive force, effectively opposite to that which normally would occur, in order to preclude the deterioration of the contained iron.

摘要： A device for holding a wheelchair stationary on a floor has a pair of notched plates at their rearward ends adapted to abut a transverse barrier upstanding from the floor and to be releasably engaged at their forward ends by a bail fastened to and swinging from the floor to engage the forward ends of the notched plates with sufficient resilient force to lock the wheelchair in position.
