Abstract: A fluid dosing cartridge (110) comprising a fluid reservoir (112), a delivery conduit (114) with an output nozzle (22), a nozzle socket (24), a pump chamber (42) and plunger (44), and a check valve assembly (118). The check valve assembly (118) comprises a valve housing (26), defining a valve chamber (32), and first (34), second (36) and third (38) valve ports, and first and second check valves (28, 30). Each check valve (28, 30) comprises a stainless steel ball (46) resiliently biased under the action of a spring (50) and a valve seat (48). The valve seat (48) comprises a body member (52) and a circular wall member (56) defining a valve aperture (54).

Abstract: The present invention relates to a system for cooling a beverage, the system comprising: a beverage line (5) connectable to a beverage supply for transporting beverage from the beverage supply through an insulated carrier to a dispensation site (1), a cooling medium generator (2) for generating a cooling medium; a cooling line (6) for transporting the cooling medium from the cooling medium generator through the insulated carrier so as to allow heat exchange between the cooling medium in the cooling line and the beverage in the beverage line; and a pump (3) for pumping the cooling medium through the cooling line. The cooling medium generator (2) is an ice slush generator. The present invention also relates to a method of cooling a beverage flowing through a beverage line using ice slush as a cooling medium.

Abstract: The present invention relates to devices and methodology for determining the variation in concentration of chromophores within an epithelial tissue. The devices comprise a means of illuminate the skin at one or more points and at wavelengths corresponding to specific chromophores. The device further comprises a detection means configured to detect the intensity of light remitted from the epithelial surface, a processing means configured to interpret image data sets obtained by the detection means and an output display to display the results or significance of the results. The invention further extends to a method of interpreting the distribution of chromophores within a lesion of an epithelial tissue. The method comprising the steps of illuminating an epithelial surface, determining the intensity of remitted light, analysing said intensity data to determine variation in the intensity across the lesion and providing an output corresponding to the extend of variation across the lesion.
