    Detection of known and novel genes encoding aromatic ring-hydroxylating dioxygenases in soils and in aromatic hydrocarbon-degrading bacteria (2002)

    Notes: Primers were designed and successfully used to screen aromatic hydrocarbon-degrading bacteria for the presence of class II aromatic ring-hydroxylating dioxygenase (RHD) genes and to amplify novel RHD genes from DNA extracted from soil using the polymerase chain reaction. Two previously undiscovered groups of genes encoding putative class II RHDs, designated the S and T clusters, were found in RHD different soil samples. Only one of 70 RHD gene fragments amplified from these soil samples could be assigned to a cluster of previously reported RHD genes. These results suggest that distinct and potentially numerically dominant groups of as-yet unrecognized aromatic hydrocarbon-degrading bacteria exist in soils.

    Presentation and gripping of flexible materials (1995)

    Notes: Examines studies into the automated handling of flexible materials suchas fabrics, paper and food products and the behaviour of such materialsduring handling, concentrating on the two most crucial aspects ofpresentation and gripping. Looks at the problems caused by lack of obviousreference points with many flexible materials and looks at solutionsinvolving overhead cameras and multiple cameras. Outlines the various typesof grippers which can be used for non-rigid materials, coveringmechanical action grippers, intrusive grippers and surface attractiongrippers. Concludes that understanding the properties of the material to behandled is very important when selecting both presentation strategies andgripping technology.

    Pinching grippers for the secure handling of fabric panels (1996)
    Bradford : Emerald
    Assembly automation 16 (1996), S. 16-21 
    Details
    ISSN: 0144-5154

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Describes one of the most frequently occurring processes in automated garment manufacture - the picking and placing of fabric panels. This can be carried out using pinch grippers which comprise two pegs that are pushed down on to the top of the fabric. The pegs are then brought together so that the fabric buckles up and is secured between them. It is essential that this operation has very high reliability and repeatability as an error can result in distorted, badly placed or misaligned fabric panels, which would then lead to the production of a faulty garment. The important parameters are the frictional characteristics of the peg surface/supporting surfaces combined with the weight and bending stiffness of the fabric, the opening distance of the pegs and the downward pressure applied to them. Describes a model for these relationships and uses experimental data on frictional and bending properties to predict the gripping behaviour for a given gripper design and gripping strategy. The predictions are compared with experimental results.
