Abstract: A personal computer includes a PBX control program and one or more switch cards located in expansion board slots. The one or more switch cards are coupled to one or more port expansion units (PEU), which are coupled to telecommunication lines out to the various extension phones at the customer premises. Each PEU contains its own digital signal processor (DSP) so that distributed digital signal processing may be implemented to avoid any bottlenecks. One master PEU is coupled to a switch card by a time division multiplexed (TDMA) bus as well as a packet switched control bus, and all the other PEUs, if any, are coupled to the master PEU by extensions of the TDMA and packet switched buses. The TDMA bus carries PBX real time conversations while the packet switched bus carries control information, voicemail outbound message data packets, and inbound voicemail data packets.

Abstract: In a convective system that includes a blower to thermally treat and pressurize air, a convective device to receive and convect the thermally-treated pressurized air, and an air hose to conduct a flow of thermally-treated pressurized air from the blower to an inlet port in the convective device, an interface device is provided to control the flow of air at the interface where the inlet port and an end of the air hose operate to conduct the flow of air out of the air hose into the convective device. The interface device is received at the end of the air hose and operates to support the flow of air out of the end when the end and the inlet port are brought together. The interface device operates to stop, inhibit, or restrict the flow of air out of the end when the end and the inlet port are separated.

Abstract: A spinstand having a vacuum chuck clamping mechanism for securing magnetic discs includes a cap (9) and a base (10). A disk-to-be-clamped is held between the cap (9) and the base (10). Vacuum, applied through a port (4) in a mounting screw (12) of the base, provides the clamping force. The vacuum is held constant using a circumferential seal (27) on a piston (2) of the cap, which extends into a cylindrical countering bushing (3) extending from the base. In one form, the cap (9) is centered about a spin axis (SA) extending through the base (10), using a hardened pin (1) extending from the cap and a locating bushing (19) affixed to the base. When the cap (9) is inserted into the base (10), the pin (1) prevents a piston (2) in the cap from contacting the inside walls/sealing surface (11) of the centering bushing (3) of the base.

Abstract: A headstack locator assembly for locating and fixing a headstack on a spinstand and which mitigates the aforementioned prior art limitations. The headstack locator assembly includes a headstack locator received on a fixed locator. The headstack locator connects to a headstack, while the fixed locator is permanently secured to a spinstand. A vacuum is used to clamp the headstack locator to the fixed locator for testing of the headstack. Upon test completion, the headstack locator is released from the fixed locator by applying positive air pressure to the assembly.

Abstract: A method for financing real estate purchases using a shared equity model is disclosed. In the disclosed method, the land portion of the real estate is financed using a land lease agreement, while the improvements to the land (e.g., a house) are purchased under a typical mortgage scenario. The land lease agreement provides for a required minimum annual return on investment to the land equity investor over a predetermined term. The borrower must pay an additional required minimum monthly payment, which may be made to the lender to pay down the mortgage, in addition to the payment required under the mortgage such that the additional required minimum monthly payment is sufficient to meet the required minimum annual return specified in the land lease agreement. Finally, the borrower may defer lease payments to the equity investor, and pay them at some date in the future.

Abstract: A PBX system using an unmodified personal computer as the host server and using expansion slots to couple one or more switch cards to the system bus, and, optionally including a network interface card to couple the PBX system to other client computers running telephony enabled applications to control the PBX via a local area network. The switch card(s) are each coupled to a chain of one or more port expansion units that do not consume expansion slots. Each PEU contains a DSP and a microcontroller, an FPGA and port interface circuitry to interface to POTS CO lines, extension telephone lines, T1 lines or PRI lines. The personal computer is programmed with a PBX process that controls operations of the overall system and may also be programmed with conventional voice mail applications or integrated voice response and other applications to implement various telephony functions such as recording voice mail or prompt callers to input DTMF tones indicating what they want to do.

Abstract: The invention provides methods of disintegrating or reducing the particle size of elemental materials, such as various forms of carbon, and organic crystals that contain minerals and that do not contain minerals. The method include the steps of entraining the material in a gas flow through an inlet of a housing, subjecting the flowing material to a plurality of alternating pressure increases and decreases within the housing, disintegrating the flowing material with the pressure increases and decreases, thereby reducing the mean particle size of the material, and discharging the disintegrated material though an outlet of the housing.

Abstract: A stable aqueous suspension of water-soluble polyacrylamide particles is in a saturated solution of an ammonium salt. The polyacrylamide particles are characterized by a particle size of about ?150 mesh, and preferably ?270 mesh, with ?400 mesh most preferred. The suspension is at least about 2.5% by weight polyacrylamide. When the ammonium salt is ammonium sulfate, PAM concentrations as high as about 15% by weight can be achieved while still being easily flowable. The suspension is made by stirring the small particle PAM into the saturated ammonium salt solution. The PAM can be quickly dissolved to form a less concentrated PAM solution by adding the suspension to water or to a dilute solution, which can include calcium salts or other soil enhancers.

Abstract: A laryngeal airway device for sealing against the laryngeal opening includes an air tube with proximal and distal ends and a sealing member attached to the distal end. The airway device includes a tubular extension or snout for delivering air directly into the laryngeal opening; the snout is tapered and “hooded” in a manner that facilitates effective positioning of the airway device. The sealing member includes a coupler for coupling the device to an introducer. Complementing the laryngeal airway device is an introducer that includes a track for receiving the coupler of the laryngeal airway device and guiding the sealing member to a sealing position with respect to the laryngeal inlet.

Abstract: In a convective treatment system a wind-actuated instrument mounted near an end of an air hose provides, generates, issues, or sounds an audible alarm when the end becomes disconnected from a convective device and pressurized air continues to flow through the end. The instrument may be mounted on an interface device receivable on the end. The interface device may include means for reducing or stopping the flow of air through the end in response to the disconnection.

Abstract: A method of producing an aqueous solution of water-soluble polyacrylamide (PAM) with a concentration of at least about 5 grams per liter includes the steps of providing a monovalent or divalent cation salt solution, and preferably a calcium salt solution, and adding water-soluble PAM particles to the salt solution such that the PAM particles are essentially all dissolved within about 10 seconds. The PAM particles are characterized by a particle size that is about −100 mesh and consisting essentially of molecules having a molecular weight of at least about 15 million a.u. Preferably, the small PAM particles are produced by a mill that produces bulk quantities of small dry, flowable PAM particles from larger commercial grade particles. Small PAM particles produced in such a mill are essentially all soluble in plain water within about 10 seconds. After solution, the polymer concentrate can be diluted with water to make stock solutions of the polymer for some purposes.
