A confectionary fountain assembly enables user to self-serve confectionary liquid, such as liquid chocolate. The fountain assembly comprises a base assembly, a conduit assembly, a functional sculpture, and an annular basin. The base assembly supports a bowl-shaped receptacle and houses a heating element and a motor assembly for respectively providing chocolate-liquefying thermal energy and rotational movement. The conduit assembly is coupled to the motor assembly and the receptacle and comprises a liquid chocolate lifting auger. The sculpture assembly receives the lifted chocolate and imparts pressure thereto for further directing the chocolate to a sculpture outlet. The chocolate, upon exiting the outlet, covers an outer decorative surface of the sculpture and returns to the receptacle. The outer basin is supported in concentric relation about the receptacle and provides a second pooled confectionary liquid source, the pooled confectionary liquid sources and the outlet confectionary liquid enabling the user to self-serve confectionary liquid.

The present invention provides a tool handle comprising an elongate shaft having a work end and a curved gripping end. The work end is adapted to be secured to a tool head and the curved gripping end is adapted to downwardly curve from a centerline through the elongate shaft to form an obtuse included angle. Also provided are tools comprising the tool handle and a tool head.

Method for producing silicon carbide fibers by mixing discontinuous isotropic carbon fibers with a silica source and exposing the mixture to a temperature of from about 1450° C. to about 1800° C. The silicon carbide fibers are essentially devoid of whiskers have excellent resistance to oxidation and excellent response to microwave energy, and can readily be formed into a ceramic medium employing conventional ceramic technology. The fibers also may be used for plastic and metal reinforcement.

A high-flow rate, low-noise, gas sampling apparatus for collecting particulate such as biological, chemical, and radioactive material from a gas on a collector such as an impaction collector includes a housing having an inlet and an outlet and a fan disposed within the housing for drawing the gas into the inlet, past the collector for sampling, and exhausting the gas through the outlet. The fan is operable to produce a flow of gas through the housing of greater than about 50 liters per minute with a noise level emitted from the apparatus being less than about 60 decibels. The apparatus may be configured as a compact, unobtrusive, portable, lightweight apparatus for use in various indoor or outdoor locations. The apparatus may also include a sensor for the detection of radioactive material collected on the collector, a processor for monitoring the sampling, and the apparatus may be linked to a communications network such as the Internet. Methods for collecting particulate from a gas are also enclosed.

A method of filling a flexible pouch having a base and sidewalls extending from the base to define a mouth. The method composing the steps of delivering the pouches to an infeed conveyor (28) to a predetermined orientation and transporting the pouches in a controlled manner toward a filler station (D,E,F), and transferring the pouches from the infeed conveyor to a transport conveyor (90) in which the pouch is gripped adjacent to the mouth as to be suspended from the transport conveyor. Opening the mouth of the pouch to permit filling at the filling station passing the pouches through the filler station, closing the mouth and sealing the mouth prior to release from the transport conveyor.

A vascular sensing system includes blood flow restricting means, a sensor, and means for producing an output representing a return of blood flow after the blood vessel has been temporarily collapsed by the blood flow restricting means. The blood flow restricting means is capable of placement on a human toe having a blood vessel, and is capable of manipulating the blood vessel. The sensor is operably connected to the blood flow restricting means and is physically spaced from the toe. Further, a method of vascular sensing includes taking pressure measurements with an pressure cuff positioned on a toe, and conducting a waveform analysis of the pressure measurements to determine a return of blood flow pressure.

A sampling cartridge for a gas sampling apparatus includes a shell having a cylindrical wall and a sampling window extending through the wall. A pair of spools are coaxially and internally positioned within the shell. The spools are independently rotatable relative to the shell. A first spool may include multiple interval sample collectors while the second spool includes a duration sample collector. Each spool also has a window closing surface which is positioned adjacent the window whenever an access door of the gas sampling apparatus is opened. The sampling cartridge may also include a fully encapsulated section of sample collector material as a negative control, and an integral RF tag for storing chain of custody information including personal identification information of a cartridge replenisher.

A fire fighting trainer is provided for use in training fire fighters and passenger rescuers during aircraft simulated cabin fires and simulated landing gear fires and during simulated oil spill module fires. The trainer includes a mockup aircraft, a mockup fuel spill module, a liquid fuel and vapor fuel supply system, and a fire control system. A method of training fire fighters and passenger rescuers is also provided.

A fire fighting trainer for use in training fire fighters to extinguish jet crash fuel fires and the like, the trainer includes a supply pipe and control valve, a distribution pipe with holes, an open tank with a diffuser being a mixture of water and gravel within which the distribution pipe is disposed, so that liquid propane jets out from the holes, then passes as vapor bubbles to the diffuser surface, then collects as propane vapor on the surface, and a gas pilot flame device for lighting the propane vapor to form flames on the diffuser surface. The simulated flames look very similar to jet crash liquid fuel flames.
