The invention relates to a method of controlling a smoke generator. The smoke generator is adapted to be connected to a supply of a pressurized gas and a supply of a smoke liquid and further comprises a valve to regulate the pressure of the gas, a fluid driving means, a mixing unit for mixing the smoke liquid and the gas, and a heat exchanger heating the mixture of the pressurized gas and the smoke liquid to vaporize the smoke liquid and form a smoke upon ejection into surrounding air. The control method according to the invention then comprises the steps of receiving a smoke density parameter indicative of a desired amount of smoke to be generated by the smoke generator, measuring a gas pressure at a position between the valve and the heat exchanger, and using these parameters in controlling the valve. The invention further relates to a smoke generator arranged for performing the control method.

A hand-held apparatus for the application of a sunless tanning composition to the skin of a user. The apparatus includes: a housing, the housing enclosing: an air mover, a nozzle, and a reservoir. The reservoir and nozzle are in operable gaseous connection with the air mover such that in use, a composition in the reservoir is expelled through the nozzle to form a spray. The apparatus is useful in methods for spraying a tanning composition onto the skin of an individual.

A light beam emission system includes: a blower that forms a flow path in which aerosol flows; and an emitter that emits a light beam. At least part of the light beam propagates along the flow path of the aerosol.

The present disclosure provides a coating apparatus and method for applying a coating of a therapeutic agent, comprising an openable and sealable device compartment, a therapeutic agent positioned in communication with the device compartment, a thermal source for vaporizing the therapeutic agent, and a vacuum source in fluid communication with the device compartment.

The invention relates to a coating material for use in a hot-melt coating method, said material containing as the main constituent one or more polyglycerol fatty acid, each obtained by way of a complete or partial esterification of a linear or branched polyglycerol containing two to eight glyceryl units with one or more fatty acids, each containing 6 to 22 carbon atoms.

A system (1, 101, 201) for spraying hot-melt adhesive onto glued surfaces comprising a melter (61) to heat hot-melt adhesive, an air compressor (60), a power and control system (63) and a gun (10). The gun (10) is connected to the melter (61) by a pipe (53) with screw connectors (54, 55), through which a hot-melt adhesive being heated flows, and the air compressor (60) by an air pipe (56) with screw connectors (57, 58) through which a pressurized compressed air flows. The gun (10) has a nozzle (20) with a hot-melt adhesive outlet or orifice (21) and a compressed air outlet (23). The pipe (53) through which flows the hot-melt adhesive having a viscosity between 2500 mPa.Math.s and 7000 mPa.Math.s and a temperature between 120° C. and 200° C., and a density between 0.8 kg/dcm.sup.3 and 1.4 kg/dcm.sup.3, and the air pipe (56) are fitted in an insulating layer of a hose (50), and wherein the throughput of the pipe (53) through which the hot-melt adhesive being heated flows is between 0.5 kg/h and 1.5 kg/h, while the air pipe (56) has a throughput between 0.1 m.sup.3/min and 0.6 m.sup.3/min.

A disposable coating applicator container for applying a coating of a therapeutic agent upon an object to be coated. The disposable coating applicator container includes a sealable container, the sealable container having a container bottom, the container bottom having upwardly extending walls, each upwardly extending wall terminating in an upper edge, and a closure for sealing a device compartment formed in part by the upwardly extending walls, the closure adjacent to the upper edges of the upwardly extending walls; and a therapeutic agent positioned in fluid communication with the device compartment, wherein the disposable coating applicator container comprises a flexible material and is in the form of a bag-like structure.

A hazer, method of controlling a hazer, and a system including one or more hazers are provided. The hazer includes a peristaltic pump, a heater, and a controller coupled to the peristaltic pump and the heater. During hazer operation, the controller actuates the peristaltic pump to pump fluid into the heater, and causes the heater to vaporize the fluid to form a haze. The controller may similarly actuate the pump and heater in each hazer of the system to form haze. In this way, more consistent pump operation and less pump failure rates may be observed in contrast to piston pumps. Additionally, the hazer may include various other features including at least one of an air pump with variable flow rate, a fan with tachometer for detecting fan errors, RDM error reporting, low voltages, a fan sponge, a pressure sensor, OTD for determining heater errors, and HVAC attachments.

Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes a low temperatures that do not deform the device. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.

A light beam emission system includes: a blower that forms a flow path in which aerosol flows; and an emitter that emits a light beam. At least part of the light beam propagates along the flow path of the aerosol.
