Abstract: The present invention provides a tubular member and a burner with a tubular member that is capable of improving the flavor of a food product having undergone roasting treatment. A tubular member that is a part of a burner with a tubular member is attached to a tip of a gas burner, and has holes through which the combusting flames pass. This configuration eliminates gas odor from a food product having undergone roasting treatment. Thus, the flavor of the food product having undergone roasting treatment can be improved.

Abstract: A vehicle propulsion system includes a rotor shaft defining a cavity within the rotor shaft and a radial hole extending from the cavity to an external surface of the rotor shaft, and a restrictor that reduces a flow of liquid through the radial hole in response to a rotational speed of the hollow rotor shaft exceeding a predetermined threshold rotational speed.

Abstract: A needle guide assembly for inserting a needle into the body of a patient in order to access a subcutaneous target, such as a vessel, is disclosed. In one embodiment, the needle guide assembly comprises a needle guide body that is configured to at least indirectly and removably attach to an image producing device, such as an ultrasound probe. The needle guide body defines at least first and second elongate guide channels. Each guide channel defines a unique insertion angle with respect to a longitudinal axis of the ultrasound probe. Further, each guide channel is configured to accept needles of differing gauges. In other embodiments other needle guide assemblies are disclosed that include multiple guide channels for inserting a needle at a variety of insertion angles into the patient's body. Related methods are also disclosed. In yet other embodiments, needle guide assemblies including needle stop features are disclosed.

Abstract: A removable vent (1) for an air ventilation system, the vent comprising: a frame (2) configured to allow the vent to be removably mounted within an opening; a grille (3) configured to allow the passage of air through the vent from a first face to a second opposing face; and a passive air flow diverter (4, 5) extending beyond the first face (7) of the vent and configured to redirect air flowing laterally across the first face to flow through the vent.

Abstract: An air conditioning register including a plurality of adjustable slats coupled to respective pinion gears. The pinion gears may engage with a rack gear so that a linear motion of the rack gear translates into a rotational motion of the pinion gears. A driving gear coupled to a shaft may be used to drive the rack gear. The shaft can be driven by a manual tool of suitable length, or by electrical or electronic methods. The manual tool and/or electronic methods may be so designed that a user can rotate the shaft without being in close proximity to the register.

Abstract: An air diffuser for underfloor air and electrical distribution systems, which can be rapidly converted to a cable grommet assembly, is provided with a diffuser grille having generally helical slots that produce a swirling air flow pattern with low impulse, low turbulence and high induction of room air. The helical air slots allow the grille to be rotated or spun off a mold, which allows the grilles to be molded more rapidly and economically. The grille sits on a housing which contains a flow regulator. Both the housing and the flow regulator have side walls with air slots. The regulator is connected to the grille and can be rotated by rotating the grille to regulate that air flow through the diffuser. The air diffusers and cable grommet assemblies are supported by common mounting systems that can be installed through the floors overlying an air distribution and/or electrical cable plenum.

Abstract: An air outlet vent (1) adapted to be mounted in a floor (6) and connected to a heating, ventilating and air-conditioning air supply duct (30) includes a cylindrical housing (2) and a cover plate (4) that covers the top open end of the housing (2). The plate (4) includes a first group of air outlet openings in the form of concentric circular arcuate slits (11) extending over a first sector of the plate (4), and a second group of air outlet openings in the form of radially extending slits (12) in a second sector of the plate (4). The plate (4) is rotatably adjustable in the housing (2). With this arrangement, the direction of the main air flow axis of the air flow pattern generated by the vent can be infinitely rotationally adjusted around an imaginary inverted cone, to direct the air flow where desired and avoid undesirable drafts, while still providing a highly turbulent twisting or spiraling air flow characteristic.

Abstract: A floor mountable air outlet adapted to distribute a generally vertical or a generally horizontal air stream is disclosed. The outlet includes an uppermost plate having an inner and an outer series of openings inclined relative to the plane of the plate. The plate forms the upper surface of a cylinder and there is mounted within the cylinder a disk shiftable toward and away from the plate. In the uppermost position of the disk the inner series of openings is blocked resulting in a generally vertical air flow, whereas in the lowered position of the disk a generally horizontal flow is obtained.

Abstract: A floor well air distribution outlet for forming a trumpet shaped air stream includes a cylindrical casing the open upper end of which is covered by a distribution disk having radially extending slots. A plate spaced below and parallel to said disk includes an inflow opening concentric with the disk. The radial outermost extremities of the slots are defined by soffits sloping downwardly toward the axis of the disk. A first series of soffits is inclined at a steeper angle than the soffits of a second series intervening between the first series. A cover plate includes radially extending tongues partially overlying the slots, the radial extent of the tongues being such as to overlie the innermost radial extremity of the slots of the second series only. A valve is vertically shiftable between two positions respectively unblocking or blocking the inflow opening.

Abstract: A ceiling outlet and process for producing same is provided with outlet slits and air deflector slats for blowing supply air from an air-guide system into a room, wherein mountings for holding slats are bent in a metal sheet, a steel plate or a plate of another material.

Abstract: In an outlet, in particular for introducing cold air into a room, having a housing (1) made of side walls (2) and a room-side cover plate (3) with outlets (4), a refrigeration assembly (11) is to be inserted in the housing (1). The refrigeration assembly (11) comprises a covering (12) with a cylinder-like air inlet (20) and a cooling unit (13). The latter is assigned at least one fan, preferably however two fans (14, 15) inside the cylindrical air guide plate (20).

Abstract: A ventilation device comprises a hollow body having an air inlet end and an ir outlet end, swirl disk associated with the air outlet end and a perforated disk associated with the air inlet end.
