Abstract: A blow moulded container has a body portion defining a chamber for storing liquid and a neck portion extending from the body portion. The body portion defines a central longitudinal axis and said neck portion is coaxial therewith. The body portion defines an upper shoulder region of curved profile and the neck portion defines a circular cylindrical portion having side walls concentric with and parallel to said central longitudinal axis. The lower end of the cylindrical portion defines a closed loop and has a non-planar intersection with the shoulder region of the body portion.

Abstract: A method of producing a plastics milk container involves blow molding a parison in a mold tool configured to produce a container having a body with a handle eye which defines a central axis extending in a first direction through the body, and a footprint with a longitudinal axis extending in a direction perpendicular to the first direction. The footprint defines four major sides and four major corner regions, each corner region arranged between a respective two of the major sides. The longitudinal axis extends through a center point of the footprint, and the maximum radial extent of the footprint from the center point is greatest where the footprint intersects the longitudinal axis, corresponding to the location of two of the corner regions, so that the extent of parison stretch away from the mold tool split line is less than the extent of parison stretch along the split line.

Abstract: A blow moulded plastics container for storing liquid (e.g., milk) has a body with a central axis intended to be generally vertical during storage. A part line of the container bisects an integral handle on the body. The body defines a footprint having a width which is greater in a middle region than at either longitudinal end of the footprint. The body has opposing side surfaces extending in a direction at least generally aligned with the part line of the container and forming part of the footprint. In one embodiment, the footprint is longer than it is wide and is asymmetrical about a transverse axis extending in a direction perpendicular to said part line. This reduces thinning effects associated with blowing a parison in a mould cavity.

Abstract: A device to measure the amount of light able to transmit through a liquid. The device uses a light detector and light source mounted to a support mechanism such that the detector and light source define a path of light emitted by the light source and detected by the detector. The device uses a structure designed to surround a liquid to be tested such that the structure allows light to transmit through the structure and the liquid. An actuator engenders relative motion between the support mechanism and the structure such that at certain times the light propagating between the light source and the detector passes substantially through the structure and the liquid to be tested such that the amount of light able to transmit through the liquid is detected by the detector, and at other times the light propagates directly from the light source to the detector without passing through the structure or the liquid such that the amount of light emitted from the light source is directly detected by the detector.

Abstract: A device to measure the amount of light able to transmit through a test liquid sample. A single lamp is used to illuminate a liquid sample cell containing the test water. A light detector is fixed relative to the lamp and is used to detect the amount of light from the lamp able to transmit through the liquid sample cell. The liquid sample cell is shaped in such a way as to provide at least two sets of opposed side walls that are able to transmit the light emitted from the lamp, where each set of opposed side walls defines a different path length through the liquid sample in the liquid sample cell. A rotation mechanism is used to provide relative rotation between the liquid sample cell and the lamp/light detector assembly. A microprocessor connected to the light detector calculates the light transmitted through at least two different path lengths through the liquid sample. Using these calculated transmittances the microprocessor then calculates the overall transmittance of the test water.

Abstract: A device to measure the amount of ultraviolet (UV) light transmitted through a water sample, relative to the amount of UV light transmitted through a sample of known UV transmittance, known as UV percent transmittance (UVT). A single UV sensor is used to measure the amount of UV light transmitted through the blank sample and through the water sample under test. In order to maintain accuracy, compensation must be made for fluctuations or drift in the UV lamp output which is common in UV lamps and due primarily to changes in temperature and imperfections in the lamp. The UV sensor measures the amount of light being emitted by the lamp at the times before and/or after the UV sensor measures the amount of UV light transmitted through the blank and water samples. A microprocessor computes the UVT while using the detector readings to compensate the calculated UVT for any drift and fluctuations in the UV lamp output.

Abstract: A system and related techniques and data structures present a Web based or other client application or service with a relational node structure to access, store and manipulate XML-based or XML-compliant data. Unlike unmodified XML information for instance stored in document object model (DOM) format, the inventive platform may load a relational node structure encapsulating XML-compliant information in an organized structure having pointers to next peer, parent, child and other links to related or unrelated information. Searching, querying and other operations may therefore be made more efficient since an entire tree structure need not be exhaustively traversed to locate desired data, but instead sorted via those relational linkages. Client applications such as Web browsing, email, contacts managers, calendars and others may therefore operate on XML or XML-compliant data without the loading or performance disadvantages which conventional XML platforms may incur.
