Abstract: A method to improve the health and growth of suckling dairy calves on dairy farms includes supplementing calves' diets with a ruminal fluid preparation obtained from the rumen of a cow. This supplement provides the calves with the protection needed to develop faster and healthier. It also leads to a decreased incidence of scours in the treated calves.

Abstract: A deicing formulation which includes at least one carefully selected and further processed agricultural by-product selected from BCS, DCS and CCSL, a chloride salt and water. The formulation has a viscosity of 100 to 140 centipoises at 0° C. (32° F.), and a liquid adhesion rating of at least 4. Each of BCS, DCS and CCSL contain a low molecular carbohydrate fraction in an amount sufficient to lower the freezing point threshold value of the formulation.

Abstract: In a waste heat recovery system wherein a heat exchanger derives heat from an engine exhaust, a venturi is fluidly connected to an engine exhaust port so as to thereby increase the flow rate and reduce the pressure in a manifold which is fluidly connected between the venturis and the heat exchanger. A fan is provided downstream of the heat exchanger to draw hot gases from the manifold, through the heat exchanger and discharge it to ambient. But when the fan is not operating during periods in which the engine is operating, the lower pressure manifold will draw ambient air in through the fan and through the heat exchanger, with the ambient air then being entrained in the exhaust gases being discharged from an exhaust channel downstream of the venturi. In one embodiment, a plurality of heat sources are provided with each having its own venturi connected to the common low pressure manifold.

Abstract: A multiple pass, parallel tube heat exchanger with a collection header extending along the length of each of a first and second pass, is provided with a bypass tube which fluidly interconnects the downstream end of the collection header to a midpoint thereof, near the end of the first pass tubes and the beginning of the second pass tubes so as to enhance the flow distribution of two-phase refrigerant from the collection header to the second pass tubes. The distribution flow is further enhanced by the insertion of an eductor nozzle within the collection header, and with the inlet of the eductor nozzle being supplied by refrigerant flow from the condenser to thereby provide a motive flow of two-phase refrigerant in the loop which includes the latter half of the collection header and the bypass tubes.

Abstract: A configurable FSM engine generates specific configurations for different state machines based on configuration data using a common method. A common configuration structure is used for all state machine implementations. Changes in the state machine design drive changes in the configuration data instead of in executable software. Multiple software state machines are thus implemented using a configurable approach. In addition, state machine processing is performed periodically and state transition events are handled without the need for an event driven operating system.

Abstract: In a waste heat recovery system having a superheat controller, a reference superheat controller operating trajectory is established and compared with operational superheat controller trajectories from time to time and measuring the deviation therebetween to determine whether a low charge condition exists. If such a condition does exist, warning steps and possibly shut down steps can be taken. As a verification of a low charge condition, the absence or presence of oscillations in the pressure and/or pump power conditions can be observed.
