Abstract: A print head module for delivering ink to a print head comprising a module venting system comprising a one-time vent built into the interior of the print head module in which, when an amount of ink comes in contact with the one-time vent, air is prevented from passing through the one-time vent. A system for delivering ink to a print head comprising a print head, a external reservoir of ink, and a print head module comprising a one-time vent built into the interior of the print head module and fluidly coupling the print head to the external reservoir of ink, in which, when an amount of ink comes in contact with the one-time vent within the print head module, air is prevented from passing through the one-time vent.

Abstract: The present invention is directed to systems and methods of creating and deploying electronic forms for collecting information from a user using a browser, where the browser may be one of a plurality of browser platforms. Characteristics of forms are entered by a human designer using a form designer by using drag-and-drop operations, and stored in XML template files. The form may be previewed by the designer. When a user on the Internet (or an intranet) requests a form by a browser, the characteristics of the browser are sensed and a form appropriate for the browser is deployed to the browser by a form server. Information is then captured from the user. The form may also be saved or printed.

Abstract: Image acquisition apparatus is used to obtain images of contents of containers for use in, for example, antibiotic susceptibility testing. The apparatus has image capture means, such as a scanner (6) for obtaining images of the contents of the containers which are supported on receiving means (1) for receiving the containers and positioning them within the field of view of the scanner (6). In addition, light deflecting means, such as reflectors, are provided for defecting light from identification markings on the sides of the containers into the scanner (6) to enable the latter also to obtain an image of said markings, and thus to enable the apparatus to identify each container.

Abstract: An apparatus for measuring optical characteristics of liquid samples, clinical samples for example, has an optical head (21) which is adapted to scan past a rack (12) of sample containers first in one direction and then in the opposite. The optical head has reference and test light sources (22) and corresponding light detectors (28) and separate optical paths are provided in the head for developing reference and test beams passing through the scanned samples. A fixed band pass filter is provided in the reference path and a filter wheel with a plurality of different band pass filters is provided in the test path, the apparatus being arranged to index the requisite filter into the test path in dependence upon the results of the reference scan. The optical head is driven by a reversible stepper motor (26) via a toothed drive belt (27) and this enables the output signals from the detectors to be correlated to the specific samples in the rack.

Abstract: Antibiotic liquids of different concentrations are dispensed to wells of a multi-well tray through an array of nozzles connected to an array of perstaltic pumps operated to supply predetermined quantities of the liquids in co-ordination with upward movement of a support for the multi-well tray from a loading position. A suspended drop of liquid is formed at each nozzle and the drops are dispensed by contact between the wells and the drops.

Abstract: An attachment for a building structure comprises a securing means shaped to locate on a corner of a structure. Two arms are supported by the securing means so as to extend divergently to locate along adjacent faces of the structure to opposite sides of the corner. The arms are provided with engagement portions at their remote ends for engagement into a respective one of the adjacent faces of the structure. A single adjustment means is arranged to effect sliding of the arms along the adjacent faces towards the corner to urge the engagement portions into clamping engagement with the structure.

Abstract: A method of installing or adjusting belt weighing machines to reduce errors in the weights recorded applies to machines having a conveyor belt (25) which is driven over a series of idler rollers (22, 24, 23) in which one or more idler rollers (24) are supported by a weight sensing system. In a first adjustment the isolation of the weighlength is improved in a static test by altering the separation between the first threshold idler roller (A, A') and either the adjacent non-weighed idler roller (B, B') or the next but one weighed idler roller (D, D'). In a second adjustment the theoretical weighlength is adjusted by moving the first threshold idler rollers (A, A') to compensate for the disparity between static and dynamic test results.
