Abstract: An apparatus for treating food must, such as grape must, may include a food must chamber configured to apply an electric pulse to the food must in a manner that causes an electric field to be generated within the food must. A pulse generator may be configured to deliver an electric pulse to the chamber that has a pulse width of between 10 and 100 nanoseconds. The chamber and the pulse generator may be configured such that they cause the electric field that is generated within the food must to be at least 1 kV/cm.

Abstract: A multi-purpose chair/stretcher assembly is disclosed which includes seat, backrest and leg supporting assemblies, the backrest and leg supporting assemblies both being pivotably mounted to the seat assembly. A pair of telescoping linkage assemblies connect the backrest and leg supporting assemblies so that the pivotal movement of one with respect to the other causes both to rotate in the same direction if restricted from telescoping. If this linkage assembly is allowed to telescope, the backrest assembly may be moved independently of the leg supporting assembly. A second linkage assembly connects the leg supporting assembly with the seat assembly. This second linkage assembly, while extendable and contractable, may be locked in a rigid configuration so that the leg supporting assembly may be held in a fixed position with respect to the seat assembly.
