Abstract: In one embodiment, a hydraulic simulation model corresponding to a real-world hydraulic network is loaded in a hydraulic modeling and simulation application executing on a computer system. The hydraulic simulation model represents leakages as pressure dependent emitter flow at selected nodes (leakage nodes). Optimization criteria include a specified maximum of possible leakage nodes. A genetic algorithm (GA) generates trial solutions for an optimization, each trial solution representing locations for leakage nodes and corresponding emitter coefficients. A hydraulic analysis is performed for the trial solutions to generated model-simulated results. The model-simulated results are compared to field-observed data for the real-world hydraulic network to generate goodness-of-fit values. The process is repeated until a particular goodness-of-fit value is achieved or a maximum number of iterations is reached.

Abstract: A fluid transfer assembly for transporting medicinal substances. The fluid transfer assembly includes flexible tubes and a manifold each comprising silicone. The manifold has an inner protrusion and connector portions having inner walls. Free ends of the tubes are inserted into complementary configured inner walls of the connector portions until each of the free ends abut the inner protrusion, which creates a continuous uninterrupted passageway between the inner bores of the tubes through the manifold.

Abstract: A method of dividing the total leakage losses of a pipe network into intrinsic background leakage and burst leakage, the method comprising: defining a first infrastructure condition factor (ICF) which is a numerical representation of the condition of a network in a threshold good condition in which intrinsic background leakage can assumed to be a negligible proportion of the total network leakage losses; defining a second ICF which is a numerical representation of the condition of a network in a threshold poor condition in which intrinsic background leakage dominates total leakage losses; deriving a network ICF for the network under consideration which expresses the condition of the network as a numerical fraction of the difference between the first and second ICFs; determining total leakage losses from the network by performing a network analysis on the network; and multiplying the total leakage losses by the network ICF to divide the total leakage losses into intrinsic background and total network burst lea

Abstract: A double-lift Jacquard mechanism in which the heddles are connected to resilient metal blades which pass through first and second plates that are reciprocated transversely of the blades in opposite directions, the blades having catches thereon which are selectively engaged by bars on the first plate to raise the associated heddles and having shoes thereon which engage the second plate to lower the associated heddles when the second plate is reciprocated, and the blades being deflectable to select the engagements thereof with the plates by deflection magnets which are under the control of a pattern selecting device to determine which directions the respective blades will be moved in by the plates.

Abstract: In a tufting machine for making patterned pile fabric, each thread passes on two successive guiding pulleys horizontally spaced from each other and selectively displaced vertically independently from each other by the hooks of a loom Jacquard. A thread-lowering beater bar is vertically reciprocated between these pulleys in unison with operation of the machine to draw from the supply bobbin a predetermined length of thread for the formation of a pile loop by the corresponding needle of the machine, a unidirectional thread clamping device being provided between the second pulley and the needle to prevent thread being drawn from the needle itself. The length of thread thus fed to the needle at each advancing stroke of the latter thus varies as one or both of the pulleys are raised by the Jacquard. A stationary bar may be disposed at an adjustable height laterally of the pulleys to permit of altering the length of thread fed to the needle when the adjacent pulley is low.
