Abstract: A switch housing body has a base and a sidewall having an axis and extending from the base to a rim and having a pair of axial slots. A switch cap has: a cap body having a top web; and a sidewall extending from the top web to a rim and having a pair of holes. A shaft passes through the pair of axial slots and pair of holes. A spring biases the cap axially away from the housing from a compressed condition to an extended condition. A cap electrical contact and a housing electrical contact have an electrically closed condition at the compressed condition.

Abstract: An air filter includes an air filter pack includes air filtration media folded along fold lines to define adjacent walls separated by connecting peaks at the fold lines; and a beam defined on both sides of the air filtration media and extending transverse to the fold lines. A frame can enclose the filter pack, and methods for making are also disclosed. The beam can be formed of cured adhesive and reinforces the filter against bending due to upstream air pressure.

Abstract: In a method for manufacturing a turbine engine element such as a blade or vane, the element has an airfoil. The method includes: applying a load across an assembly of a first cast portion of the airfoil and a second cast portion of the airfoil; and applying current across a junction of the first cast portion and the second cast portion to fuse the second cast portion to the first cast portion.

Abstract: A silver-plated product which has more excellent minute sliding abrasion resistance property than that of conventional silver-plated products, and a method for producing the same. The silver-plated product is produced by electroplating a base material 10 of copper or a copper alloy to form an underlying plating layer 12 of nickel or a nickel alloy, a first silver-plating layer of silver (lower silver-plating layer) 14, a zinc-plating layer 16 of zinc serving as an intermediate plating layer, and a second silver-plating layer of silver (upper silver-plating layer) 18 serving as a surface layer, in this order from the base material 10.

Abstract: A shock resistant body comprises a non-metallic lattice structure having a first region with a first foam density in a first region and a second foam density in a second region that is lower from the first foam density. The first region has solid lattice members of a larger cross-sectional area than those in the second region and the first region has smaller interstices between solid lattice members than those in the second region.

Abstract: A method of cooling a component during laser cladding can include attaching a flow adapter to the component, flowing cooling fluid through the flow adapter, flowing the cooling fluid through the component during laser cladding. Attaching a flow adapter to the component can fluidly communicate at least one adapter channel to one or more component channels, and flowing cooling fluid through the at least one adapter channel can pass cooling fluid through the one or more component channels to cool the component during laser cladding. The method can include laser cladding the component.

Abstract: A heat exchanger for providing thermal energy transfer between a first flow along a first flowpath and a second flow along a second flowpath has a plate bank having a plurality of plates, each plate having: a first face and a second face opposite the first face; a leading edge along the second flowpath and a trailing edge along the second flowpath; a proximal edge having at least one inlet port along the first flowpath and at least one outlet port along the first flowpath; and at least one passageway along the first flowpath. An inlet manifold has at least one inlet port and at least one outlet port. An outlet manifold has at least one outlet port and at least one inlet port. The first flowpath passes from the at least one inlet port of the inlet manifold, through the at least one passageway of each of the plurality of plates, and through the at least one outlet port of the outlet manifold.
