Abstract: A barbecue grill cart assembly is provided having a unique leg locking system at each corner. The locking system provides a plurality of contact points for each leg to obviate any swaying or twisting of the legs. The lower shelf includes extruded bolt receiving apertures which mate with corresponding apertures in the legs. The side shelves having a locking system including elongated slots which provide positive engagement and prevent accidental lowering of the shelves.

Abstract: A compound liquid flow meter comprised of a main flow path incorporating a turbine meter (2,36) and a downstream valve (3,24), and a parallel auxiliary low flow path incorporating a relatively small capacity meter (8,41) and a fixed orifice (16,53) discharging into the main flow path downstream of the valve. The orifice size is selected to cooperate with the diameter and spring characteristics of the valve so that on increasing flow rates the valve begins to open at 45 to 55 percent of the capacity of the low flow meter (8,41) and on decreasing flow begins to close at the same flow rate. The valve action is smooth and does not require, or create, pressure impulses or surges. Furthermore, the balanced relationship between the orifice and the valve virtually eliminates the traditional loss of accuracy associated with the "change over" of prior art compound meters.
