The optical fiber spooling ring includes a plurality of 360 degree rotations of the fiber cable.

Abstract: A thermal management system includes a closed-circuit refrigerant system to circulate a refrigerant fluid. The system includes a compressor to compress a flow of the refrigerant fluid. The system includes a condenser coupled to the compressor. The system includes a receiver to store at least a portion of the refrigerant fluid. The receiver is coupled to the condenser. The system includes a pump to circulate the refrigerant fluid through at least a portion of the system. The pump is coupled to the receiver. The system includes a flow control device to control the flow of the refrigerant fluid to an evaporator. The flow control device is coupled to the pump. The evaporator extracts heat from at least one heat load that is in thermal conductive or convective contact with the evaporator.

Abstract: A turbine wheel for use in a gas turbine engine having a plurality of blades attached to a rotor disk. Each blade is formed from a composite comprising ceramic matrix material. The blades each include a root that fits within dovetail slots of the rotor disk and cooperates with a blade retention assembly to couple the blades to the rotor disk.

Abstract: A controller equipped with a user interface having multiple-day programming capabilities, including methods of programming such devices, are disclosed. The user interface may include one or more menus or screens that can be used to program a schedule for one or more selected days during the week. An illustrative method of programming the controller may include the steps of entering a scheduling routine, selecting multiple days for schedule modification, changing the schedule parameters for one or more periods during the selected days, and then exiting the scheduling routine.

Abstract: A touch region for a controller having a touch screen that, when touched, makes a setting change to the controller. In one illustrative embodiment, the controller displays a display image on the touch screen, wherein the touch screen has a defined touch region that when touched makes a setting change to the controller. The display image has a portion that coincides with the touch region, wherein when the touch region is touched, at least part of the portion of the display image that coincides with the touch region changes from a first display image to a second display image to indicate a setting change of the controller. A subsequent touch to the touch region may cause at least part of the portion of the display image that coincides with the touch region to change from the second display image to a third display image to indicate a subsequent setting change of the controller.

Abstract: Barriers for flood defence and other purposes are often constructed using sand bags. The strength of these barriers is limited and the invention seeks to address this problem. The invention provides a tie formed as a single injection moulded item placed between layers of sandbags to help to hold them together. The tie has two rigid triangular end plates (4) and (5) linked by a flexible arm (11). The end plates are formed with protruding spikes (6) shaped with a barb so that they will easily penetrate the fabric of a sandbag but are difficult to pull out. In use, each tie is placed between layers of sandbags so that spikes of respective plates (4) and (5) become anchored to adjoining bags. The bags of the barrier are thus held together and any irregularities in it are accommodated by the flexibility of the arm (11). Slots (14) and lugs (15) allow a plurality of ties to be linked together as may be required when oversize sandbags are employed.

Abstract: A system for inspecting rail tracks for loose connections (4, 7) employs moulded plastic caps (8). The caps carry arrows (9) or other indicators aligned with a datum direction such as the direction of the rails. Any loosening of the connectors (4, 7) is immediately apparent from the fact that the arrows are no longer aligned. The invention avoids the need for individual manual torquing of each connector during routine safety inspections.
