Abstract: A dispensing tip assembly includes a foodstuff additive dispenser for a pressurized foodstuff container. A tip body of the dispensing tip assembly may have low pressure zone in which fluid pressure is lower than fluid pressure upstream of the low pressure zone as flowable foodstuff from the foodstuff container flows through the internal flow passage toward an open downstream end of the tip body. The dispenser tip assembly may include one or more of duckbill valves tethered to one another, and/or a plurality of injection ports and/or structure for one-direction dispensing, and/or internal fins to couple to an actuator of the foodstuff container, and/or an anti-rotation device, and/or a collar for attaching a bulb or pod of the tip body, and/or an ergonomic and functional bulb.

Abstract: A method and apparatus for mixing additives into a fluid fuel at a predictable concentration. The method involves taking a sample of the fuel; mixing the additive into the sample in metered proportions; testing the sample to determine that the correct amount of additive is present; storing the remaining fuel until it is time for the fuel to be used; and mixing the additive into the remainder of the fuel in the same metered proportions.

Abstract: A method and apparatus for calculating the derived cetane number of a liquid hydrocarbon sample is disclosed. The method comprises combusting (19) the sample in a constant volume combustion chamber (45). The method comprises obtaining (23) a pressure versus time combustion profile (69) of the sample wherein the profile comprises a first region (81) and a second region (83), the first region (81) including the start of combustion, and the second region (83) relating to a later time than the first region. The method comprises selecting a single data point from the second region (83) of the combustion profile (69), said data point representing a combustion delay (CD) of the combustion profile; and calculating a derived cetane number for the sample using the time value associated with said single data point.

Abstract: An apparatus for measuring the vapour pressure of a liquid hydrocarbon sample is disclosed. The apparatus comprises a sealed chamber (25) for receiving the sample. The chamber (25) is at least partially defined by a moveable element (26) such that moving the moveable element (26) alters the volume of the chamber (25). The apparatus comprises a displacement sensor (29) configured to measure a displacement of the movable element (26).

Abstract: A height-adjustable work station includes (a) a partition wall having an internal wall frame and axially opposed first and second exterior wall surfaces mounted to the wall frame, the first and second exterior wall surfaces spaced axially apart by a wall thickness; (b) a carriage support located within the wall thickness and mounted to the wall frame, the carriage support including a vertical track; (c) a carriage mounted to the carriage support in sliding engagement with the track; (d) a work surface assembly movably supported by the carriage on a first side of the wall; and (e) a linear actuator mounted within the wall thickness and coupled to the carriage, the actuator configured to vertically translate the carriage along the track for facilitating height adjustment of the work surface assembly.
