Granted: 1994-05-17
Abstract: TITLE:  PIPE BURSTING AND REPLACEMENT APPARATUS AND METHOD        Abstract of the Disclosure:    Tool for slitting and laterally expanding underground steel gas mains and inserting replacement plastic piping into the spread apart pipeline has a forward end cylindrical portion mounting a single, rearwardly angled blade to make only one line of cut, and a conical pipe spreader portion at its rearward end.  The conical spreader portion is eccentrically disposed with respect to the forward end cylindrical portion.          A single roller type pipe slitter aligned with the fixed blade may be mounted on a removable extension of the forward end cylindrical portion, to initially groove and weaken the pipe along the intended line of cut.  A pneumatically operated impact ram is attached to the rearward end of the tool, as is the leading end of the replacement piping.  A wire cable pulls the tool through the underground pipe, thereby grooving, slitting and laterally expanding the pipe.  The spacing of the roller slitter in advance of the fixed knife blade is dimensionally related to the length of any coupling or clamp as may be anticipated along the line of cut, and the spacing distance of the fixed knife blade forwardly of the conical spreader portion is related to the cone angle of the latter to increase hoop tension immediately in front of the fixed blade as the cutting proceeds.

Filed: 1992-02-28
Granted: 1995-10-17
Abstract: In the present invention, a target receiver terminal information storage unit stores a plurality of target receiver terminal numbers corresponding to a plurality of target receiver terminals.  The control unit determines idle/busy information stored with a corresponding terminal number as a pair, selects a target receiver terminal number according to a predetermined priority, and outputs the selected number.  A sender can thereby automatically call up an appropriate target receiver terminal by dialing a registered receiver identification number.   The control unit uses connection information as well as idle/busy information as a determining element in selecting a number.  Therefore, a registered number conversion service user can distribute calls to a plurality of target receiver terminals.  Besides, the user can select a plurality of target receiver terminal numbers through an inquiry to a switching unit  about the idle/busy state without storing idle/busy information or connection information in the storage unit.

Granted: 2003-07-29
Abstract: In an industrial building housing a production operation utilizing a liquid material exposed to the atmosphere, a relationship is maintained between the plant atmosphere and the liquid material whereby the atmosphere is not receptive to vaporized or atomized portions of the liquid. The building is maintained under a slight positive pressure throughout to prevent random and uncontrolled infiltration of outside atmosphere. The temperature and relative humidity of the building atmosphere and the temperature of the liquid are closely monitored and maintained at levels relative to one another which assure that the building atmosphere is not receptive to evaporated or atomized liquid. Air handling units for supplying conditioned air to the building interior include heat exchangers and evaporators for regulating the wet bulb and dry bulb temperatures of the air being admitted to the building interior, and thus the temperature and relative humidity of the atmosphere within the building. The liquid material recirculates through a heat exchanger for removal of accumulated heat as necessary to maintain it at a temperature relative to the dry bulb/wet bulb temperatures of the building atmosphere below that at which it would tend to migrate by vaporization or atomization into the building atmosphere.

Title: Lipospheres for controlled delivery of substances
Inventor: DOMB ABRAHAM J
IPC: A01N25/26
Filed: 1990-11-08
Granted: 1999-04-13
Abstract: Solid, water-insoluble lipospheres formed of a solid hydrophobic core having a layer of a phospholipid embedded on the surface of the core, containing biologically active agent in the core, in the phospholipid, adhered to the phospholipid, or a combination thereof, are disclosed for use in providing extended release of active agent, including drugs such as vaccines and anesthetics, insect control agents such as insecticides and repellents, and agricultural compounds such as fertilizers, fungicides, pesticides, and herbicides. Lipospheres can be prepared by a melt technique or a solvent technique, summarized as (1) forming a liquid solution or suspension of the agent by either melting the agent, or dissolving or dispersing the agent in a liquid vehicle, to form a mixture of liquid agent that solidifies at room temperature or greater; (2) adding phospholipid and an aqueous solution to the liquid agent to form a suspension; (3) mixing the suspension at a temperature above the melting temperature until a homogeneous fine dispersion is obtained; and then (4) rapidly cooling the dispersion to below the melting temperature of the liquid mixture containing the agent. Agent can also be added to the phospholipid or mixed with the resulting lipospheres. The agent containing lipospheres  have several advantages over other delivery systems, including emulsions, vesicles and liposomes, including  stability, low cost of reagents, ease of manufacture, high dispersibility in an aqueous medium, a release rate for the entrapped substance that is controlled by the phospholipid coating and the carrier. Examples demonstrate the effective administration of anesthetics, antigens, and insect repellent (DEET).
