Abstract: A latch for securing a wafer to a clamp plate. The latch may include a bearing that couples a wheel to a horizontal shaft. The horizontal shaft is adapted to rotate relative to the clamp ring so that the wheel secures the wafer. The bearing minimizes the amount of particles generated by the moving components of the latch that may contaminant the wafer.

Abstract: A clamp useful for firmly securing a camper housing within the bed of a pickup truck which allows for efficient attachment or removal of the camper housing. The device includes a U-shaped clamp body having a pivotal connector at one end that is affixed to the camper housing and a reciprocally movable, spring biased arm having a roller at its free end such that the roller engages the lip of the pickup truck bed to permit pivotal movement over center to effect spring locking action of the clamp. The device allows a camper housing to be readily installed or removed from a vehicle bed by manual actuation of the holding clamps.

Abstract: A clamping or gripping device comprises a handle by which the device can be held in one hand to position it relatively to the work, a carrier mounted or mountable on the handle, or on a part on the handle, a first jaw carried by the handle, and a second jaw pivotally mounted on the carrier. The carrier is movable along the handle, or along a part on the handle, to move the second jaw bodily towards and away from the first jaw; and there is pivotally mounted on the carrier a lever so arranged that, when the device is being held by the handle in one hand to position it relatively to the work, the lever is movable by the same hand, as that which is holding the handle, in a direction towards the handle to cause leverage to be exerted on the second jaw to cause clamping or gripping pressure to be applied, against the work, in the direction of the first jaw.
