Abstract: A computerized system and method for processing an order for food and/or drink without requiring a waiter or waitress to take the order is improved by incorporating an advertising scheme into the system whereby advertisements are selected by an establishment server having a customized data base, said selection being based on any combination of various parameters, such as patron identity, ordered menu items, time of day, etc. and then communicated to the interactive stations from which patrons enter their orders for electronic display thereon. A plurality of establishment servers may be connected to a central server and the central server may control the entirety of the advertising process by selecting the ads to be stored in each establishment server data base as well as the parameters governing the selection process.

Abstract: A method and apparatus for high volume distillation of impure liquid, particularly of binary mixtures of relatively low boiling organic substances and water, comprises fractionally distilling the impure liquid to form a vapor of a low boiling organic substance; compressing the vapor; passing at least a portion of the compressed vapor through a vapor composition adjustment zone wherein the organic substance may catalytically or otherwise react or merely stabilize following compression; compressing the vapor exiting the adjustment zone to form a recompressed vapor; cooling the recompressed vapor in heat transfer relation with the impure liquid whereby the vapor at least partially condenses, transferring sufficient heat to the impure liquid for evaporating the liquid and to form the aforementioned low boiling organic vapor; and collecting the condensed low boiling organic vapor.

Abstract: EtOH-H.sub.2 O binary mixtures to serve as raw feed liquids for distillation and vapor treatment systems intended for the production of substantially anhydrous ethyl alcohol are desirably derived from the fermentation or enzymatic conversion of sugars. A preferred source of sugars is honey which may be produced in massive volumes in environmental controlled structures containing vegetation, hives and bees which are associated with automted devices for emptying the hives of their accumulated honey. In one system, the honey is produced on honeycombs which are removed from the hives and emptied by immersion in hot water. Honey is recovered from a water solution thereof by separation of melted wax and fermented to a 6-12% beer suitable for use as a raw feed liquid.

Abstract: A method and apparatus for high volume distillation of impure liquid comprises evaporating the impure liquid in an evaporator to form a vapor at a temperature above the freezing point and below the boiling point of said liquid at atmospheric pressure and at a pressure not exceeding a pressure corresponding to the evaporation temperature under saturated conditions; compressing the vapor; passing a portion of the compressed vapor through an expansion engine to do work upon and motivate the engine and to produce shaft energy, whereby the vapor expands and cools; bypassing the expansion engine with the remainder of the compressed vapor and admixing the remainder directly with the expanded vapor from the expansion engine in a mixing chamber; adding work to the expansion engine to supplement the work done by the vapor expanding therethrough to make up for work lost when the remainder of the compressed vapor bypassed the expansion engine and for other work lost; cooling the admixed vapor in heat transfer relation wi

Abstract: Chemical bleaching pretreatment processes are provided for cotton goods and other cellulosic materials which have the effect of enhancing the bleached cloth whiteness levels and/or reducing the bleaching time or intensity. The goods may be pretreated by intimately contacting them, as by immersion in a bath, in an alkaline scour solution having a pH of 10 to 14 and a temperature of 160.degree.-212.degree. F. for from 5 seconds to 31/2 minutes. A second and separate pretreatment involves immersing the goods in such an alkaline scour solution and, immediately prior or subsequent thereto, in an acid solution having a pH less than about 3 at a temperature in the range 45.degree. to 212.degree. F. for from 1 to 10 seconds. Optionally, either the alkaline scour pretreatment or the combination acid/alkaline scour pretreatment may be preceded by an up to 31/2 minute water dip or rinse in water ranging from just above ambient to 212.degree. F.
