Abstract: An improved engine system is provided which includes a synthetic low temperature sink that is developed in conjunction with an absorbtion-refrigeration subsystem (23) having inputs from an external low-grade heat energy supply (21) and from an external source of cooling fluid (24). A low temperature engine is included which has a high temperature end (22) that is in heat exchange communication with the external heat energy source (21) and a low temperature end (36) in heat exchange communication with the synthetic sink provided by the absorbtion-refrigeration subsystem (23). By this invention, it is possible to vary the sink temperature as desired, including temperatures that are lower than ambient temperatures such as that of the external cooling source. This feature enables the use of an external heat input source that is of a very low grade because an advantageously low heat sink temperature can be selected.

Abstract: Ultrafiltration is employed to preferentially pass an ultrafiltration (UF) permeate containing flavor and aroma components while retaining spoilage microorganisms in a UF retentate. The UF retentate is then treated to inactivate a sufficient number of spoilage microorganisms to inhibit spoilage of the juice under storage conditions. A UF permeate containing flavor and aroma components is then recombined with the UF retentate to provide a food juice suitable for storage while avoiding the loss or alteration of the desirable flavor and aroma components of fresh juice encountered in conventional juice processing. If desired, spoilage enzymes can be retained in the UF retentate and inactivated to inhibit deterioration of desirable juice qualities. Further, the UF permeate can be further treated by reverse osmosis to concentrate flavor and aroma components in an RO retentate. If desired, the acid content of juice can be reduced by passing a portion of the RO retentate or UF permeate through an ion-exchange column.

Abstract: On filling of e.g. liquid products into packing containers via a filling pipe it is of great importance that the valve should be capable of interrupting completely and effectively the flow of contents, since otherwise after-dripping product may soil the outside of the packing container and hinder the formation and sealing of the top of the same. Contents of high viscosity or those containing particles cause particular difficulties, since such materials easily stay behind on the outside of the valve and after the closing of the valve tend to drip onto the packing container. In one arrangement for a filling valve on a packing machine the after-dripping is prevented in that the outside surfaces of the valve which can come into contact with the contents are cleaned with the help of a pressure fluid during operation of the machine. To make this possible an arrangement in accordance with the invention comprises a filling valve 7 whose valve body 13 is provided with a channel 9 for the supply of pressure fluid and an outlet opening 15 situated at the lower end of the valve body 13 which conducts the pressure fluid and causes it to flow along the underside of the valve body so that any residues of the contents are effectively flushed away.
