The assembly of the present invention includes a liquid dispensing device having conduit means for delivering liquids from a storage chamber to a mixing chamber, from which the liquid product is dispensed, and valve means incorporated in each conduit. The assembly further includes a flow meter for each liquid which operates to produce an output signal proportional to the quantity of liquid flowing through the conduit. A control means receives the output signals and operates on detecting that flow of one liquid exceeds a predetermined amount, by closing the flow control valve associated with that liquid. Upon detecting that the proper proportion is achieved, the control means signals the valve to reopen.

Device for dispensing liquids in a desired ratio

A polymer blend comprised of a polyketone and linear low density polyethylene (LLDPE). The blend is suitable for use with foodstuffs and liquid hydrocarbons. In a preferred form of the invention, the polyketone has an alternating structure of (a) units derived from carbon monoxide and (b) units derived from one or more olefinically unsaturated compounds.

Polymer blends

Food packaging comprises a blend of polyketone and PVC. The blends show good oxygen barrier properties without serious deterioration of moisture barrier performance. Terpolymers of ethylene, propylene and CO are preferred. PVC having a K-value of 50 to 80 are preferred.
