Abstract: A rotary valve (1) particularly suitable for use in a turbocharger for an internal-combustion engine, the rotary valve provided between a turbocharger inlet port (10) and at least first and second scroll passages (13, 14), the rotary valve rotatable between (a) a position at which at least one scroll passage is blocked and a bypass outlet is blocked, (b) a position at which no scroll passage is blocked and the bypass outlet is blocked, and (c) a position at which no scroll passage is blocked and the bypass outlet is not blocked. The control valve is rotatable about a central axis, includes a disk-shaped base (2) and a control surface (4) provided upon said base, the control surface preferably being generally wedge shaped, and the disk optionally having an aperture (7) for communication with the bypass outlet. The rotary valve is preferably mounted on both sides via a shaft (112a, 112b) extending through the axis of rotation.

Abstract: An indexing device including a housing, a cassette support mechanism, a cassette, and transport apparatus carried by the housing. The transport apparatus includes a bed of rollers having a common plane and a drive assembly coupled to the bed of rollers. The cassette support mechanism is mounted in the housing and movable along a pathway between a raised position and a lowered position relative the bed of rollers. The cassette is mounted on the cassette support mechanism.

Abstract: Apparatus for manipulating wafers comprising a fixture including seats each for receiving and supporting a wafer in a seated condition and an element mounted for reciprocal movement in opposition to the fixture between a retracted condition and an extended condition into an opening of the fixture for engaging a wafer held by the fixture in the seated condition.
