Abstract: A liquid concentrate generation system may comprise a manifold having an inlet receptacle including a first piercing member, an outlet receptacle including a second piercing member, and a flow channel connecting the inlet receptacle and outlet receptacle. The system may further comprise a cartridge having an inlet port and an outlet port sealed by a respective first and second cover. The inlet and outlet port may be respectively configured to displace within the inlet receptacle and outlet receptacle from an unspiked position to a spiked position. First and second piercing members may be in communication with the flow channel and spaced apart respectively from the first and second cover in the unspiked position. The first and second piercing members may be isolated from the flow channel and may respectively puncture the first and second cover in the spiked position.

Abstract: A compressor for a heat transfer circuit includes a variable frequency drive (VFD), an electric motor that rotates a driveshaft, bearing(s) for supporting the driveshaft, a backup gas supply, and a power supply. During a utility power interruption, the backup gas supply operates utilizing DC electrical power generated by a back electromotive force of the electric motor. A method of operating an electric power supply system for a compressor includes operating in a utility power mode and operating in a backup power mode during a utility power interruption. In the utility power mode, AC electrical power is supplied from the VFD to the motor. In the backup power mode, DC electrical power generated in the VFD by a back electromotive force of the motor it used to operate a backup gas supply to supply compressed working fluid to gas bearing(s) of the compressor.

Abstract: Hub structures inter-connectable with and/or connected to elongated frame members (e.g., rod-type members) to form frames. In certain non-limiting, example, embodiments, hubs which have simple configurations and/or which are connectable to elongated frame members (e.g., rod-type members) employing small numbers of connectors (e.g., one screw-type connector per frame member/hub connection) and/or which are more easily assembled/disassembled to frame members for constructing and/or deconstructing frame structures.

Abstract: Display panels made at least partially of stretch fabric are disclosed. Different ways of mounting these display panels onto supporting structures such as folding frames are disclosed. The display panels can be used indoors and outdoors. The versatility of the display panels makes them an excellent display media for trade shows and temporary exhibitions.

Abstract: An accounts payable system in which invoices submitted by electronic data interchange (EDI) are audited for duplicate invoices prior to them being entered into the production database, or environment. Pre-processor logic audits, identifies and returns electronically duplicate transmissions. At this pre-processor level, all inbound invoices are sorted in credit/debit sequence. Invoices are posted (committed to the production accounts payable environment; that is, to the accounts payable data base) one at a time so purchase order history is current for each evaluation. Inbound invoices are sorted by credit/debit. Only debits are audited.
