Abstract: There is provided a stand for a canned heat fuel cell wherein the stand has a side wall, an upper marginal edge and a lower marginal edge, the side wall being sized to be slightly larger than the fuel cell side wall, inwardly extending groove dividing the side wall into upper and lower portions with the upper portion having a height greater than the lower portion and also having a plurality of apertures to permit an air supply therethrough, grill bars for sheeting on the top of the side wall, the arrangement being such that the stand will sit on the upper marginal edge of the canned heat fuel cell. The arrangement provides an efficient means of using the fuel cell while preventing bums to the user and/or damage to the substrate surface.

Abstract: A candle holder includes a housing having a mounting mechanism for mounting a candle to the housing. A display is connected to the housing for selectively displaying one of a plurality of numbers thereon, whereby the candle holder can be re-used for different occasions, such as birthdays and anniversaries, having different numbers associated therewith.

Abstract: A spark-generating device for a lighter that has a sparker configured and adapted to produce sparks, and preferably a cover configured and adapted to substantially prevent operational contact of the sparker by a finger of a user during actuation of the sparker, the device including at least one manipulable member configured and adapted for manipulation and movement by a user and having at least two associations with the sparker. In a first association, the manipulable member is independently movable with respect to the sparker, and in an operable association, the manipulable member is coupled with the sparker to move the sparker.

Abstract: A system for environmentally acceptably disposing of BTEX and/or VOC containing off gases, including entrained vapors and liquids that originate from gas processing equipment including a flare stack communicating at an upper end with the atmosphere, a steam cup supported within the flare stack, a gas inlet extending into the flare stack and into the steam cup and serving to convey off gasses into the flare stack and collect any entrained liquid carried by the off gasses and a burner positioned within the flare stack below the steam cup and connected to receive and burn a combustion gas/air mixture, heat produced by the burner serving to vaporize any entrained liquid collected in the steam cup and to combust any BTEX and/or VOC components of the off gasses and vaporized liquid into inert oxidized states that pass out the flare stack upper end.

Abstract: Surgical apparatus for providing extracorporeal pneumoperitoneum. One embodiment provides a reversely turned fluid and gas impermeable fingerless sleeve (14) with a quick connect and disconnect assembly around the cuff of the sleeve (14) for sealing around an abdominal incision to allow hand-assisted minimally invasive surgery under conditions of pneumoperitoneum. A dome shaped enclosure (62) is provided for use with the quick connect and disconnect assembly to seal around an abdominal incision and maintain pneumoperitoneum during interruptions in a surgical procedure. Another embodiment incorporates a fingerless sleeve (14) which is adhesively secured directly to a patient's skin around an incision. The sleeve is applied over a pre-gloved surgeon's hand, and an outer surgical glove (18) is applied over the sleeve (14) in the region where the fingers and thumb protrude before the sleeve (14) is reversely turned on itself for connection to a patient.

Abstract: In a gas-burning apparatus, such as a furnace, a device for reducing NOx emissions includes a cup member mounted proximate to an inlet to a combustion chamber of the apparatus and a perforate member attached to the cup member and located in the combustion chamber at a predetermined distance inwardly from the inlet. The perforate member has a plurality of holes to define a mesh pattern through which the flame and other products of combustion are constrained to pass within the combustion chamber. The perforate member acts as a heat sink to reduce the flame temperature, thereby inhibiting NOx production.

Abstract: A conveyor oven has a modulating gas valve which raises and lowers the thermal output of a burner that heats the oven. A bypass line passes a minimum amount of gas to prevent the burner from completely shutting down during periods while the oven remains above a threshold demand for more heat. Electrical isolation is provided between temperature controlling devices to prevent an electrical feed back which might otherwise prevent a complete shut down of the oven during hazardous conditions.

Abstract: A tunnel baking oven comprises at least two oven trains, which are disposed side by side and parallel to a direction of throughput, having an inlet station and an outlet station. A baking chamber extends in each oven train from the inlet station as far as to the outlet station. Furthermore, provision is made for at least one energy cell heating the baking chambers. A continuous baking conveyor belt extends in each baking chamber from the inlet station as far as to the outlet station, the baking conveyor belts being drivable at the same rate as well as at different rates.

Abstract: A one piece cell panel for a forced air furnace which is designed for ease of removal without the necessity of having to dismantle the furnace cabinet. The panel includes a substantially vertically disposed upper section which contains a plurality of cell inlets and cell outlets and an integral lower horizontal shelf which is disposed at a predetermined acute angle downward below the horizontal. The cell panel has a substantially rectangular front profile and an “L” shaped side profile.

Abstract: A pulsating combustor has a plurality of annular plate elements (12), which are stacked in spaced vertical alignment so as to define a central space (14). There is a plurality of slot-like passages (18), one such passage between each adjacent pair of elements. There is at least one combustion chamber (21) in communication with at least one slot-like passage. Fuel and combustion air are fed into the combustion chambers. There is a spark plug for igniting a fuel-air mixture in the combustion chamber. Preferably there is a first housing (24) defining the combustion chamber and another housing defining a collection chamber for combustion gases emerging from the passages.

Abstract: A gas lighter includes a handgrip holding a fuel tank and an electric arc generator, an actuating device pivoted to the inside of the handgrip, an ignition button mounted in an opening on the handgrip and adapted to trigger the electric arc generator in producing an electric arc for burning fuel gas discharged out of a gas nozzle in a cylindrical metal casing at one end of the handgrip and simultaneously to drive the actuating device in opening the fuel tank for enabling fuel gas to flow out of the fuel tank to the gas nozzle for burning, and a spring-supported locking lever assembly mounted in a sector slot on the handgrip and adapted to move the actuating device between the operative position and the non-operative position.

Abstract: A collapsible, portable outdoor fireplace with a fire screen assembly is easily broken down into its constituent components, which are stored in a space between the cover and bottom members of the fireplace. A fire screen assembly is supported between the cover and bottom members and includes a series of individual screen panels that are hinged together. The fireplace has a support structure that supports it off the ground and includes pairs of legs that are attached to the bottom member. The legs may extend either up through the cover and bottom members or alongside the bottom member. These support legs terminate in handle portions. The legs include moveable joints that permit the handles to be collapsed upon the cover member to retain the cover and base member together.
