Abstract: TOTAL CONTAINMENT DEVICE FOR CONNECT/DISCONNECT OF PLASTIC TUBES                    Abstract of the Disclosure A device for selectively connecting and disconnecting plastic tubes includes a welder.   A carriage is located in the welder for conveying a heated wafer through the welder.  A pair of arms is mounted in the welder with each arm having a tube holding pocket which extends across its respective arm.   The arms are movably mounted to generally align the pockets with a gap therebe-tween.  Each of the arms has a clamp for selectively clamping a tube in its pocket.   A wafer removal station is in the welder downstream from the arms.   The carriage is driven to the wafer removal station so that the wafer first passes through the yap to contact the tubes and than the wafer passes into the removal station so that it may be removed from the carriage and the carriage may be returned to its starting location.   The welder includes a computer for controlling the operation and synchronizing the timing of the carriage and the arms to automate the welder.

Title: Production of yeast product from lactose-containing sugars
Inventor: DE BOER RUDOLF
IPC: A23L1/30
Filed: 1993-05-27
Abstract: 2136744 9324610 PCTABScor01 A process for producing a substantially pure yeast product and a modified cultured yeast product from a lactose-containing substrate. The process includes filtering the substrate, inoculating the substrate with a yeast strain and fermenting it under yeast growth conditions in a bioreactor. The product of the bioreactor is then separated into a yeast cream and a centrate. A portion of the yeast cream is further processed to produce a substantially pure yeast product. The centrate is concentrated and combined with the remainder of the yeast cream to produce a yeast cream/centrate mixture. This mixture is further processed to produce a modified cultured yeast product. The combination of the yeast cream and the concentrated centrate produces a new product having potential for human and animal consumption. The further use of the centrate to produce a food supplement also reduces the amount of environmentally-undesirable waste discharge.

Title: Inflatable pump and article
Inventor: POMEROY PAUL E
IPC: E04H15/20
Filed: 1993-07-06
Abstract: The disclosure relates to a collapsible flexible pump (10) which includes an inflatable spring framework (12). The inflatable spring framework is formed by attaching a layer of flexible material over selected exterior portions of the flexible material pumping chamber to form a passageway therebetween. Inflation of the inflatable spring framework via an inflation valve (28), results in the collapsed flexible pump distending into a three dimensional pumping chamber inscribed by the inflated spring framework. The pumping chamber includes appropriate inlet and discharge valves (32, 30). By applying a compressive force to the pumping chamber, the volume of fluid within the pumping chamber is forced out through the discharge valve. The restoring tendency of the distended inflatable spring framework returns the pump chamber to the extended position on the returning intake stroke. A plurality of exemplary inflatable articles is disclosed.
