Abstract: A method and apparatus for adjusting and controlling ice bridge slab thickness and/or initiation of ice harvest following a freeze cycle. This adjusting and controlling is performed through the use of adjustable float clip assemblies which set the amount of water available for ice making in a batch process. The adjustable float clip assemblies provide an ice machine user with the ability to easily adjust the ice slab bridge thickness to a single or plurality of settings, and allow for changes in ice bridge slab thickness at the site of installation.

Abstract: In a new flexible-monoblock refrigeration configuration arrangement, all of the refrigeration components are gathered within its one and only flexible chassis platform. These units are one piece, meaning that their condenser, refrigerant control assemblies, compressor and the evaporator are fixed to their one and only integrated flexible chassis. No refrigeration components are outside its enclosure. There is no need to perform any assembling or service to the refrigeration itself at the time of installation. The new flexible monoblock refrigeration system can be configured in many different forms using parallel rigidly interconnected side plates. The sub platforms are rigidly connected to the side plates so that all of the weight, forces and stress are borne by the side plates and none is transferred among the refrigeration elements, units or subassemblies.

Abstract: Described herein are systems and methods for cryogenic fluid delivery. The systems may include a pressure vessel containing a cryogenic fluid formed of liquid and vapor that is connected to a use device via a withdrawal line. The withdrawal line connects to the cryogenic fluid in the pressure vessel via two routes, a liquid tube and a vapor line. The vapor line may include a back-pressure regulator that opens the vapor line depending on pressure in the system. The withdrawal line may include a pressure relief valve that exerts pressure on the liquid tube. A bypass line may connect the withdrawal line to the liquid tube. The bypass line has a check valve that permits free flow of cryogen from the withdrawal line to the liquid tube via the bypass line while prohibiting cryogen flow from the pressure vessel through the bypass line. The methods employ the systems described herein.

Abstract: A vehicular heat pump system may have two inside heat exchangers within an HVAC module, and may operate in mild cooling and mild heating modes. In mild cooling mode, a first isolation valve and a second isolation valve are fully open and closed, respectively, to direct the refrigerant flow to the first inside heat exchanger only. In mild heating mode, the first isolation valve and the second isolation valve are fully closed and fully open, respectively, to direct the refrigerant flow to the second inside heat exchanger only. In both modes, a first metering device is partially open to control the flow and expansion of the refrigerant, and a second metering device is fully closed to prevent the refrigerant from flowing between the inside heat exchangers. This staged operation of the heat pump system may reduce the risk of flash fog as well as reduce discharge air temperature spreads.

The shape of the cross-section of the bell mouth is made to change gradually between the first position and the second position.
