Abstract: A flow control system for chemical synthesis and production integrates automation and real-time data processing. The system comprises a plurality of valves for reagent selection, pumps for fluid transport, inline instruments, and liquid handlers for sample collection. A computer control system manages flow sequences, flow rates, sample volumes, residence times, and wait times. The system utilizes artificial intelligence algorithms to optimize process controls. Reagent selection valves positioned upstream from pumps reduce the number of required pumps and allow the use of low-pressure valves. This configuration enhances efficiency and accuracy in combinatorial chemical experimentation.

Abstract: The present disclosure provides an ice making evaporator that combines the cubic shape of pan and partition evaporators with the central ice making of a pin evaporator to achieve an ice shape that is mostly cubic.

Abstract: An ice-making machine includes an ice-forming mold in a food zone of the ice-making machine; a refrigeration system including a compressor, a condenser, an expansion device, and an evaporator in thermal contact with said ice-forming mold, thus producing a combined evaporator and ice-forming mold; and a bulkhead wall separating an equipment compartment from the food zone. A bulkhead space is located between the bulkhead wall and the combined evaporator and ice-forming mold. The bulkhead space is part of the food zone. Air in contact with ice being formed by the ice-making machine can circulate to the bulkhead space. A source of antimicrobially active gas and an air circulation system that causes the antimicrobially active gas to circulate through the bulkhead space. In use, the antimicrobially active gas flows though the bulkhead space to thereby distribute the antimicrobially active gas throughout the bulkhead space, thus inhibiting growth of microbiological contaminates.

Abstract: An ice-making machine having an ice-forming surface upon which ice is formed, a refrigeration system including a microchannel evaporator that cools the ice-forming surface, and a water-supply system. The microchannel evaporator includes a microchannel tube that facilitates a distributed cooling effect in a contact area between the microchannel tube and the ice-forming surface. In some embodiments, the microchannel tube includes a series of recessed portions that define insulated regions and divide the tube into non-insulated regions. The insulated and non-insulated regions can be dimensioned to form individual ice cubes on the ice-forming surface. In other embodiments, spaces between microchannel tubes and/or spaces between the ice-forming surface and microchannel tubes can form insulated regions at least partially defining the size and shape of ice produced by the ice-making machine.

Abstract: The valve element for attachment to a flexible bag may include one or more flexible layers intended to extend over a hole disposed through a sidewall of the bag. In its normal condition, the layer or layers are in adjacent contact to each other or to the bag sidewall and thereby cover and seal the hole. During evacuation, the layer or layers displace to provide a collapsible and expandable channel that allows air to move from the hole to an exit point. To facilitate sealing of the valve element, a tacky surface is included in the valve element. The tacky surface can have a tackiness quality that normally holds the layers and/or sidewall together but that can be overcome during evacuation to expand the channel.

Abstract: An ice machine has an ice-making assembly that includes a water distributor in which one or more structural elements form a first chamber. The first chamber is configured to receive an inflow of water, distribute the water laterally, and to controllably release the water. A mating member cooperates with the one or more structural elements to form a second chamber. The second chamber is configured to receive water from the first chamber and to controllably release the water onto a receiving surface. The mating member is configured to be detached from the one or more structural elements in a direction perpendicular to the direction of lateral water distribution.

Abstract: Provided is a valve element for venting fluids, such as gas or liquids, entrapped in a packaging enclosure. The valve element includes a base element having an aperture disposed through it and a membrane having a protruding raised portion. The membrane is attached to and overlays the base element. The raised portion is selectively configurable between a concave position and a convex position by applying an external force against the apex of the raised portion. When configured in the convex position, the raised portion is spaced apart from the aperture allowing fluid communication therethrough. When configured in the concave position, the raised portion obstructs the aperture preventing fluid communication therethrough. To vent air passing through the aperture into the environment, an expandable channel for providing a clearance is provided between the membrane and the base element.

Abstract: An ice making machine has a mechanical compartment and a water compartment that houses a water system, and a pump assembly. The pump assembly includes a motor and a pump housing connected to the motor. The pump assembly is mounted to a base between the machine compartment and the water compartment so that the pump motor is located in the mechanical compartment, but can still be removed through the water compartment. A mounting flange attached to the pump assembly extends radially beyond the circumference of the pump motor. In one embodiment, a pump opening in the base has a collar integrally formed with the base. The collar includes a sealing section and a latching section. When the pump is inserted through the pump opening, snap latches in the latching section engage the mounting flange to hold the pump in place and the sealing flange seals against an inner surface of the sealing section.

The condensate collection unit is coupled to a water discharge line, such that condensate is removed from the ice machine and does not come into contact with water that is recirculated to the evaporator. The first and second mounting brackets and first and second flanges on the sump permit easy installation and removal of the evaporator and the sump from the ice machine.

Abstract: An ice-making machine has a substantially vertical ice-forming mold for freezing cubes of ice, a water distributor for distributing water so as to cascade over a front surface of said ice-forming mold and a hinged water curtain with a bottom edge for directing said cascading water into a sump, with the hinge allowing the water curtain to swing out of the way so that ice cubes harvested from the mold may fall past the sump and into an ice collecting bin. The water curtain has an inside surface adjacent to a front surface of the ice-forming mold configured such that as a slab of ice cubes is released from the mold during a harvest cycle, the front of the slab of ice contacts said inside surface and forces the water curtain to open to a point where the bottom of the falling slab of ice cubes will not contact the bottom edge of the water curtain.
