The mixing portion is disposed between the multi-lumen dispense passage and the dispenser outlet.

A foam dispenser comprising an outer container having a closed end bottom at a first end and an open neck at a second end and defining an outer container volume therein and an actuator. The outer container volume is configured to hold a compact shampoo composition.

A pressurized liquid delivery assembly has at least one liquid delivery module. Each module may include a housing and an associated compartment. The compartment may be located within the housing and may be moveable with respect to the housing to permit access to the compartment by a user. The compartment may define a space adapted to receive a replaceable pressurised receptacle containing liquid to be dispensed by the assembly. A liquid dispenser may be operatively associated with the receptacle and adapted to dispense liquid. The dispenser may include a conduit that may be extendable from a dispensing nozzle to a liquid receiving connector. The liquid receiving connector may be adapted to releasably connect to the liquid receptacle in use.

A swivel connector for a spray gun includes a first portion, the first portion including a first interior passage that extends entirely through the first portion along a longitudinal axis and a second a second interior passage that extends along a first axis perpendicular to the longitudinal axis. The swivel connector also includes a second portion coupled to the first portion, the second portion including a third interior passage that extends entirely through the second portion along the longitudinal axis, and a fourth interior passage that extends along a second axis perpendicular to the longitudinal axis. The swivel connector also includes a connector pin coupled to both the first portion and the second portion, wherein the connector pin includes a fifth interior passage that extends along the longitudinal axis.

A process for producing a layer or a body built up of layers. A process gas which has a pressure of >10 bar is accelerated in a convergent-divergent nozzle and a coating material which is formed by particles and is composed of Mo, W, an Mo-based alloy or a W-based alloy is injected into the process gas. The particles are at least partly present as aggregates and/or agglomerates. It is possible to produce dense layers and components in this way. We also describe layers and components having a microstructure with cold-deformed grains having a high aspect ratio.

A dispensing system for dispensing a hot melt adhesive foam onto a substrate is described. The dispensing system comprises a pump having a first input to receive a hot melt adhesive and a second input to receive a gas, where the pump mixes the hot melt adhesive and the gas to produce a solution. The dispensing system also includes a temperature sensor to detect a temperature of the solution, a dispenser to receive the solution from the pump and dispense the solution, and a controller. The controller instructs the pump to operate at a first speed, receives the temperature of the solution, and instructs the pump to operate at a second speed that is different than the first speed in response to the signal.

The present invention relates to self-foaming hot melt adhesive compositions and methods of making and using the same. Self-foaming hot melt adhesive compositions are formed by admixing a dispersion concentrate including a chemical blowing agent and a compatible carrier (liquid or molten) with a molten base hot melt adhesive composition at a temperature below the decomposition temperature of the chemical blowing agent. The resolidified material is processed through a device that heats the material above the decomposition temperature of the chemical agent and cools it below such temperature before being dispensed. The device preferably includes sensors and a controller configured to prevent the material from accumulating an adverse thermal history during processing.

The present invention relates to a device and method for making sclerosing foam, which is useful in the treatment of varicose veins and other venous conditions. The device comprises a continuous pathway that is at least partly formed of flexible or compressible material and that comprises a foam generating structure within the continuous pathway; the foam generating structure being formed of two or more elements, wherein each element defines at least one passageway of cross sectional area 1 m2 to 10 mm2 and said two or more elements being arranged in series; a port which allows introduction of material into or extraction of material out of the continuous pathway; and a liquid pathway that is at least partly formed of flexible or compressible material and is arranged to deliver liquid into the foam generating structure between a first and second element of the foam generating structure.

A foam generating device includes a housing defining an agitation chamber and a conditioning chamber. A cartridge assembly arranged within the agitation chamber defines an agitation flow path of the solution to increase a quantity of a gas in the solution. A conditioning assembly arranged within the conditioning chamber defines a tortuous flow path for the solution including a plurality of cylindrical discs configured to sequentially receive the solution. Each of the discs defines a plurality of radial ribs on a first side and on a second side opposite the first side, the first and second sides separated by a floor, and a disc passage defined in the floor. The conditioning assembly is adjustable in order to selectively define the tortuous flow path with a first quantity of radial ribs and second quantity of radial ribs in order to alter the aeration of the solution along the tortuous path.

A composition for a single-component polyurethane foam and a nozzle for spraying the same. The composition comprising a polyurethane pre-polymer dissolved in liquid hydrocarbons, wherein the polyurethane pre-polymer further comprises polyethers or polyesters, wherein at least one of the polyethers or polyesters is a diol with an average functionality =2, a hydroxyl value within 35-180 mg KOH/g, and with an acid value not exceeding 0.2 mg KOH/g. The single-component polyurethane foam composition being sprayable onto a surface at a rate of 6 to 10 grams/second from the nozzle of the present invention wherein a coating depth of up to 30-55 mm is obtained over a 1 m.sup.2 surface after one minute of product application. The nozzle of the present invention comprising design features to produce a cone-shaped spray pattern of the foamable product.
