A spray apparatus comprises a housing having a fluid inlet, a plurality of tubes for dispensing fluid from the housing, and an integrating member operatively coupled to at least a subset of the plurality of tubes for effecting coordinated movement of the coupled tubes in response to movement of the integrating member. An actuator, such as a turbine or an adjustable control ring, is employed for inducing movement of the integrating member. The dispensing tubes may be flexible so as to allow for easy adjustment of the fluid-dispensing direction or shape by the application of a lateral force at one or more locations along the length of the tubes. The flexibility also facilitates amplified direction/shape changes (compared to rigid dispensing tubes) in the dispensed fluid streams, e.g., when the tubes are subjected to a lateral force on one side and an opposing pivoting force (axially offset from the lateral force) on the other side.

Spray apparatus and dispensing tubes therefore

A spray apparatus includes a housing having a fluid inlet and a plurality of fluid outlets, and a turbine carried for rotary movement within the housing under fluid flow from the fluid inlet to one or more of the fluid outlets. An integrating member is preferably operatively coupled to the turbine for oscillatory movement relative to the housing under rotary movement of the turbine, and a plurality of tubes are each disposed in one of the fluid outlets for dispensing fluid from the housing. At least a subset of the plurality of tubes are operatively-coupled to the integrating member for coordinated movement of the coupled tubes in the respective plurality of fluid outlets.

Spray apparatus

The present invention provides a spray head assembly with a moving spray nozzle that delivers fluid in a substantially uniform spray distribution. The movement of the spray nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the spray housing and nozzle to wobble. The spray pattern produced by the wobbling spray housing changes more or less rapidly so that fluid droplets or streams are directed along arcuate paths rather than at a single point. This type of spray distribution pattern is gentler than many stationary patterns and the unique design of the wobble inducing member does not include complex mechanical parts or significant flow restrictions.

Fluid delivery from a spray head having a moving nozzle

The present invention provides an apparatus with a moving nozzle that delivers fluid in a wobbling, rotating or oscillating pattern. The movement of the nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the nozzle to wobble or rotate. The moving nozzle can be used as a motor providing a rotating output shaft or ring.

The movement of the wobble turbine is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine has outlet channels disposed therein that distribute the water. The spray pattern produced by the apparatus changes more or less rapidly so that fluid droplets or streams are directed along arcuate paths rather than at a single point. This type of spray distribution pattern is gentler than many stationary patterns and the unique design of the wobble inducing member does not include complex mechanical parts or significant flow restrictions.

Spray head for use with low pressure fluid sources

The present invention provides a fluid discharging apparatus that delivers fluid in a substantially uniform distribution. The movement of the apparatus is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. In certain embodiments, the wobbling turbine then causes the body or housing to wobble.

The present invention provides improved cigarettes and other smoking articles in which the substrate is a cellulosic material, preferably paper or a paper-like material, e.g., tobacco paper. The substrate of the present invention is used to retain very high amounts of aerosol forming materials and flavorants, which, upon exposure to heated air passing through the aerosol generating means during smoking, are vaporized and delivered to the user as a smoke-like aerosol.

Cigarette with improved cellulosic substrate

A new substrate for cigarettes includes an overwrapped rod of gathered cellulose-based paper having an outer diameter of from about 4 mm to about 8 mm; wherein the paper has a basis weight in the range of about 10 g/m.sup.2 to about 90 g/m.sup.2 ; and the paper can include up to about 50 weight percent of one or more burn retardant hydrated salts. The substrate typically comprises an overwrapped rod of a gathered web of a nonwoven cellulosic material, having a length of about 10 mm; wherein the dry unit weight of the substrate rod is from about 20 mg to about 120 mg; and wherein the web of cellulosic material is embossed or scored prior to gathering, thereby providing a substrate rod with a pressure drop of from about 2 to about 40 mm of H.sub.2 O, under FTC conditions. When employed in a cigarette at a 10 mm length, the substrate is typically capable of generating an aerosol density of at least about 2000 Units for at least about 50% of the puffs, preferably for at least about 80% of the puffs (under 50/30 smoking conditions).

Cigarette with improved substrate

The present invention is directed to improvements in carbonaceous fuel elements wherein (a) the fuel elements are provided with a composite support member which assists in retaining the fuel element within the cigarette structure during smoking, and (b) the fuel elements burn at a lower average temperature than previously known carbonaceous fuel elements. In one preferred embodiment of the present invention, the fuel element comprises at least two different materials contiguous throughout the length thereof, and including one material which burns, and another material which preferably does not burn, or burns more slowly than the burnable material. The non-burning, or substantially non-burning material is advantageously a heat exchange material such as graphite. In preferred embodiments, the nonburning support or retaining member extends beyond the periphery of the burnable material such that it interacts with the insulating jacket which surrounds the fuel element, locking the same in place, particularly during smoking.

Composite fuel element for smoking articles

A cigarette including a longitudinally segmented combustible fuel element, and a substrate carrying tobacco extract and glycerin positioned physically separate from the fuel element is disclosed. The substrate is a gathered paper-type material, and is positioned in a spaced apart relationship from the fuel element. One preferred smoking article of the present invention is a cigarette which comprises (i) a symmetrical and longitudinally segmented combustible fuel element; (ii) a physically separate aerosol generating means including at least one aerosol forming material; and (iii) means for securing, maintaining or retaining the fuel element within the smoking article. The symmetrical fuel element of the present invention comprises two substantially identical end segments; a longitudinally disposed intermediate segment; and two, preferably identical, reduced cross-sectional area (or reduced circumference) segments (also called 'isolation' segments) located between each of the end segments and the intermediate segment. The symmetrical nature of the fuel element allows it to be inserted into the cigarette without concern as to any particular longitudinal orientation. Thus, when placed in a cigarette, one end segment of the fuel element serves as a burning segment, while the other end segment serves as a base segment.

A cigarette includes a longitudinally segmented combustible fuel element, and a substrate carrying tobacco extract and glycerin positioned physically separate from the fuel element. The substrate is a gathered paper-type material, and is positioned in a spaced apart relationship from the fuel element. The fuel element is composed of a carbonaceous material and is extruded in such a manner that when positioned within the cigarette, its extrusion axis is perpendicular to the longitudinal axis of the cigarette. The fuel element includes a burning segment at one end, a base segment at the opposite end, and an isolation segment between the burning and base segments. The fuel element is circumscribed by glass fibers so as to hold the fuel element in place within the cigarette.
