    Abstract: A method of welding a window frame provides a welding system (10) having movable head fixtures (16). Certain of the head fixtures include cutting structure (37) and each head fixture includes heat supplying structure (40). A one-piece lineal (20) has first and second ends and notches therein. The lineal is loaded with respect to the head fixtures, with portions of the lineal being folded about the notches to define folded corners. Head fixtures are moved to clamp on the lineal. The cutting structure cuts the lineal generally at each notch to separate each of the folded corners from the lineal, with each corner of the lineal being defined by a pair of ends. The head fixtures are repositioned so as to provide a space between each pair of ends. A heat supplying structure is inserted into the space to heat each pair of ends and then removed. The head fixtures are moved so that each pair of ends contact and join in a thermally welded manner.

    Abstract: An apparatus (60) for applying a dry film lubricant comprises a tool (62) and a pad (64). The tool (62) includes a handle (66), a cranked member (68) and a supporting member (70). The pad (64) is removably locatable on the supporting member (70). The supporting member (70) is oval in cross-section and the pad (64) includes an oval cross-section hollow member removably locatable on the supporting member (70). The supporting member (70) comprises locking means (78) to lock the pad (64) on the supporting member (70). The supporting member (70) comprises positioning means (80) to position the pad (64) on the supporting member (70). The tool (62) also has a shielding member (72) spaced from and arranged parallel to the supporting member (70). The handle (66) is arranged in a plane (A) substantially parallel to a plane (B) containing the supporting member (70) and to a plane (C) containing the shielding member (72). The pad (64) is substantially dovetail shape in cross-section to correspond to a rotor slot (40).

    Abstract: A composite magnetic card for bearing printed data and suitable for mailing purposes comprising (a) a first planar sheet of paper cardstock having a first face and second face; (b) a second planar sheet comprising a magnetic material having a first face and a second face and defining at least one detachable portion defined by a die cut while having suitably located portions integrally retained to non-detachable magnetic material of the second planar sheet; wherein the first sheet first face is sufficiently and suitably adhered with an adhesive to the second sheet first face to retain the detachable portion of the second sheet to the first sheet but wherein the adhesive is not disposed at first selected locations between the first sheet and the second sheet within the card. The resultant card after the detachable portion has been removed is adhesive-free to provide a non-sticky, clear area of the card, which may be readily used to clearly displace further desired data.

    Abstract: Within a turbine engine a heat exchanger may be provided to cool compressor air flows to be utilized for cabin ventilation or other functions. A fluid flow acting as a coolant for the heat exchanger is generally drawn from the by-pass duct of the engine and a dedicated outlet duct is provided such that the exhausted fluid flow from the heat exchanger is delivered along the conduit duct to a low pressure region. In such circumstances, an appropriate pressure differential across the heat exchanger is maintained for operational efficiency when required, whilst the exhausted fluid flow is isolated and does not compromise the usual engine ventilation vent exit area sizing. Over-sized ventilation vents would create an aerodynamic step and therefore drag upon the thrust of the engine. Typically, the outlet end of the outlet duct has a variable geometry to enable adjustment in the pressure differential across the heat exchanger such that an air fan valve used to control flow rate through the heat exchanger may not be required.
