Abstract: A wheel trolley assembly that enables easier and more efficient tire rotation is provided. Various service stations, one of which includes the wheel trolley assembly, are arranged sequentially one after the other by means of a series of conveyor means, each positioned in a manner which allows them to rotate independently of one another, while at the same time facilitating the transfer of vehicles from one station to the next. The wheel trolley assembly and series of independently-moving conveyors greatly increase the efficiency and speed of vehicle service, thereby increasing the volume of vehicles which can be serviced as well as customer satisfaction levels.

Abstract: A device for releasably fastening up to four adjacent slab corners to a support wall or ceiling. The device is positioned at a common point of adjacency of a number of slabs. A locking disk having a quadrant notch is rotatively mounted orthogonally to the surface of the slabs, and engages or disengages slots cap in the thickness of the slabs according to the angular orientation of the disk. The device is capped by a decorative rosette having an appendage projecting loop bracket shaped and dimensioned to accommodate a bud vase. The device is particularly indicated for fastening slabs used to cover adjacent funerary crypts.
