Abstract: A carton (11) with parallel flat front and rear surfaces joined by curved sides and a flip-top lid (10) hinged to the carton. The carton is composed of two superimposed layers adhesively secured at a joint line at lapped edges. The outer layer is slit along its front surface parallel to the carton ends and along upwardly extending curves around the sides to a fold line parallel to and raised above the front slit and the inner layer (12) has a cutout in its front surface above the front slit of the outer layer. The cutout curves upwardly short of the sides where tags (13) are cut out of the sides of the inner layer and the outer layer overlaps the inner layer at the carton ends. Top and bottom closures are adhesively secured to the outer layer at the ends of the carton.

Abstract: A method for the ablative reshaping of material surfaces, including the steps of providing a source of an ablative beam having a given average fluence distribution over its cross-sectional extent, determining the ablation curve of the material to be reshaped, selecting, from said ablation curve, an ascending region having an at least approximately constant slope, selecting a beam fluence from among the fluences comprised in said region, irradiating the material surface to be shaped, and controlling the geometry of the material surface thus being reshaped by controlling the total amount of energy per unit area of said surface delivered during said irradiation.

Abstract: A bypass flowmeter assembly has a plurality of branch pipes (11) connected in parallel with a main pipe (10), with at least one of the branch pipes having a respective flowmeter (14), and at least another of the branch pipes having respective selectively operable pipe closure means (12, 13). Preferably each branch pipe has a flowmeter and closure means. Preferably also control means (30) are provided to operate the closure means through a routine of successive phases of respectively different patterns of branch pipe flow. This allows derivation of main pipe flow rate on the basis of branch pipe flowmeter measurements with comparison of flowmeter outputs between different phases to eliminate high order measurement error, averaging of such outputs to reduce low order measurement error, or by computation to eliminate unknown factors. The assembly can be connected serially with a similar assembly (20) to monitor relative variations in the total flow of interest and adjust the actual measurement of this flow.

Abstract: The invention provides a method for testing for the presence of catalase in a milk sample comprising combining a milk sample with a substantially catalase-free alkaline protease enzyme enriched detergent to disrupt catalase containing somatic cells present therein and release active catalase therefrom in the present of a pH buffering salt having a concentration of at least 20 mM in the resulting sample solution and providing the solution with a pH in a range of about 7.0-8.0 and thereafter testing the sample for the presence of catalase, as well as providing a test kit for detecting the presence of catalase in milk comprising a substantially catalase-free alkaline protease enzyme enriched detergent and 20 to 400 micromoles of a pH buffer alone or in combination with any other solute capable of reducing the solubility of oxygen in milk and of providing the resulting milk solution with a pH in the range of about 7.0-8.0.

Abstract: Microorganisms isolated from soil enriched with chitin or collagen were found to be very effective in controlling soil nematodes, probably by destroying their eggs or egg-shells. Pure culture of such microorganisms were prepared. These microorganisms are formulated into solid or liquid nematicidal compositions and as such used for combating soil-nematode infestations.
