Abstract: A davit arm holder 30,50 for a davit arm 11-18 for suspending lines 4 from elevated heights by mounting the davit arm 11-18 on a structural substrate 1. The davit arm holder 30,50 comprises a base 50 formed from one or more planar layers 52 of sheet material adapted to lie parallel to the plane of a surface of the substrate 1, and an attachment 30 adapted to be fixedly attached to the base 50 and to provide a connection 32 to engage a davit arm 11-18. The base 50 includes an outer layer 52 and at least one inner mount 60. The outer layer 52 has a plurality of first engagement portions 70 that are radially spaced from a centre point 54 of the base 50. The at least one inner mount 60 is integrally formed with the outer layer 52, is fixedly securable to the substrate 1 and is adapted to space an inside surface 68 of the outer layer 52 from the substrate 1 to form a gap 66 under the outer layer 52. The base 50 is adapted to have a low-profile when anchored to the substrate 1.

Abstract: A system for controlling blade clearances within a gas turbine engine includes a rotor disk and a rotor blade coupled to the rotor disk. Additionally, the system includes an outer turbine component positioned outward of the rotor blade such that a clearance is defined between the rotor blade and the outer turbine component. Furthermore, the system includes a heat exchanger configured to receive a flow of cooling air bled from the gas turbine engine and transfer heat from the received flow of the cooling air to a flow of coolant to generate cooled cooling air. Moreover, the system includes a valve configured to control the flow of the coolant to the heat exchanger. In this respect, the cooled cooling air is supplied to at least one of the rotor disk or the rotor blade to adjust the clearance between the rotor blade and the outer turbine component.

Abstract: A sterilization enclosure to be placed within a sterilizer, the sterilization enclosure defining an interior for accommodating at least one surgical instrument and maintaining sterility of the at least one surgical instrument after the sterilization enclosure is removed from the sterilizer. The enclosure comprising a light source and a transparent window. The light source to illuminate the interior and the transparent window positioned such that the interior and the at least one surgical instrument are visible through the transparent window. A process indicator that is either disposed within the interior or coupled to an external surface of the sterilization enclosure. The process indicator in fluid communication with the interior of the sterilization enclosure such that the process indicator is exposed to a sterilant agent disposed within the interior of the sterilization enclosure to measure a characteristic within the interior during a sterilization process.

Abstract: A multi-mode ring scanner (MMRS) has a ring unit for wearing on a finger. The MMRS optionally has a wrist unit coupled to the ring unit, such as via a cable. The MMRS optionally communicates wirelessly with a computing device. The ring unit has one or more scanners (such as an optical scanner or an RFID tag reader). The ring unit optionally has two paddle switches for activation by inward pressure from fingers adjacent to the finger. The two switches enable specifying operation of the MMRS in a plurality of modes and/or to communicate a plurality of information codes to the computing device. The computing device is optionally enabled to assign a function to each combination of activation of the two switches. A scanning system including the MMRS optionally provides feedback to a user based on feedback from a host processor.

Abstract: An aerofoil having a leading edge point within a leading edge region and a pressure surface with a profile wherein within the leading edge region the pressure surface profile has a local minimum. The local minimum reduces the loss which may be caused by high negative incidence on to the blade.
