Abstract: Disclosed is an arm guard for the protection of the bow arm of an archer. The arm guard comprises an elongated rigid member attachable to a bow at the handle of the bow generally beneath the bow hand of the archer. The elongated member extends rearwardly and closely parallel to the bow arm of the archer, to a point substantially at or beyond the elbow region of the bow arm, with the rearward portion of the elongated member curving towards the bow arm. The elongated member thus presents a physical barrier to a released bow string from striking the arm of the archer.

Abstract: A loading station receives a substrate into a load-lock volume pressure isolated from a loading station chamber which is open to a processing chamber. The volume is evacuated and the substrate lowered into the loading chamber. A transport arm moves the substrate from the loading station to a substrate carrier of a cooling fixture within the processing chamber. The carrier is connected to a clamp which together move vertically downward to lower the wafer onto a substrate seat of the fixture. During substrate processing the fixture is tiltable and rotatable and provides substrate cooling by solid-to-solid conduction, forced convection and free convection.Solid-to-solid conduction is provided by the clamp. The substrate is pressed to the fixture by the cooling clamp having a circulating cooling fluid.
