Abstract: The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to closed-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, and a precipitation-resistant metal-based catalyst used alone or in combination with an amine catalyst.

Abstract: In one aspect, a computer readable memory medium comprising program instructions for graphically developing a connectivity driver is provided. The computer readable memory medium is a non-transitory medium. The program instructions are executable by a processor to generate a purchase order for a laboratory item, transmit the purchase order to a remote computer in order to communicate the purchase order to a vendor, receive an advance shipping notice generated in response to the purchase order, receive item information stored in an RFID tag of a tagged item received at the delivery location, and check the item information against the advance shipping notice in order to verify that the tagged item is the same as the ordered laboratory item. The purchase order specifies a delivery location.

Abstract: A table for supporting a grill that is designed to block wind from a grill, such as a portable grill, that is rested on the table. The table includes a rectangular bottom panel that has an upper surface, a lower surface, a front, and a back. A back panel that has a front surface, a rear surface, and a pair of ends is hingedly coupled to the back of the bottom panel and is pivotable between a deployed position and a retracted position. First and second side panels are hingedly coupled to a respective end of the back panel and are pivotable between an open position and a closed position. Each of the side panels has an inner surface and an outer surface. A pair of legs are hingedly coupled to the lower surface of the bottom panel and are pivotable between an extended position and a collapsed position.
