Abstract: An evaporator for a refrigeration chiller includes a tube bundle in which at least a portion of the tubes of the tube bundle are immersed in a pool which include both liquid refrigerant and is lubricant. Liquid refrigerant and lubricant are deposited into the pool at a first pool location. Because of the vaporization of refrigerant that occurs within the pool, a pattern of flow is established and managed that causes the lubricant in the pool to migrate from the location of its deposit into the pool to a second pool location. An outlet is provided at the second pool location from which lubricant is drawn out of the evaporator.

Abstract: The fluid supply apparatus supplies and controls one or more fluids while adjusting/controlling one or more continuously parameters; and includes an outlet, at least one control valve and a touchless user control interface. For example a faucet has sensors mounted thereon to control water flow (6) and temperature (16, 17). For example a user hand in field (16) will increase temperature over time and decrease in field (17). The on/off sensor field may include the water stream, a bi-colour light emitting diode indicates temperature, temperature feedback means maintains the desired temperature, a battery or super capacitor allows operation or fluid shut off if power fails, an anti-tamper feature requires the fluid to be shut off if more than one sensor is covered and a time prevents waster wastage. The hygienic touchless interface may be in a tile or flat plate. Other applications may include panel mounted fluid control systems for controlling a plurality of fluid types and associated parameters.

Abstract: An apparatus is provided for in-line folding and affixing a label to an article, the label having a fold line thereacross defining a foldable portion and a cover portion of the label. The apparatus comprises a transfer grid having one or more rollers to convey the label from a first end of the transfer grid to a second end of the transfer grid. An opening is defined between two of the rollers intermediate the first and second ends of the transfer grid. The transfer grid conveys the label in a substantially unfolded orientation from the first end of the transfer grid to the opening of the transfer grid such that the foldable portion of the label is projective through the opening. A folding station is adjacent the opening and receives the foldable portion of the label, urging a projecting portion of the foldable portion over the cover portion to define a substantially folded-over orientation of the label.

Abstract: A cooler of an exhaust gas recirculating system comprises a housing including coolant inflow and outflow ports and at least one bypass pipe arranged within said housing.

Abstract: A key matrix circuit has a switching circuit with a first terminal and a second terminal that are switched on and off by pressing a selection key of a plurality of selection keys arranged in an N-row-by-M-column matrix, thereby making connection to a common ground circuit when a selection key is pressed. The key matrix circuit has a first voltage-dividing circuit connected between a connection circuit that connects the first terminals of the first row and a fixed power supply voltage, and a second voltage-dividing circuit connected between a connection circuit that connects the second terminals of the first column and the fixed power supply voltage, the connection points between resistances to of the first voltage-dividing circuit being connected to the connection circuits connected to the first terminals of the other rows, and the connection points between resistances of the second voltage-dividing circuit being connected to the connection circuits of the other rows.

Abstract: A curriculum scheduling method includes receiving input data identifying target subject matter, processing the input data to determine an educational standard associated with the target subject matter, querying a database to determine curricula that supports (i.e., contains lessons relevant to) the educational standard, receiving from the user a selection of at least one curricula item from among the determined curricula, and allocated time periods for participation in presentation of the selected curricula item(s). The educational standard may include a group of requirements and the database may be queried based on a requirements selected by the user.
