Abstract: A compensator for manipulating a radiation beam traveling along an optical path. The compensator includes a fixed support holding a first optical wedge and an adjustable support holding a second optical wedge. The adjustable support includes a base, a stage holding the second optical wedge, first and second flexures, and a drive block. The stage defines a cavity and is movable relative to the base and the fixed support. The first and second flexures couple the stage to the base such that the stage translates along a stage path. The drive block is disposed in the cavity of the stage and is configured to translate along a drive block path perpendicular to the optical path and perpendicular to the stage path. The drive block includes first and second drive bearing surfaces configured to translate the stage in first and second stage directions, respectively, along the stage path.

Abstract: An alignment system configured to be substantially insensitive to thermal variations in its system during alignment measurements. The alignment system includes a sensor system, a support structure, a sensing element, a position measurement system, and an athermal interface between the sensing element and the support structure. The sensor system is configured to determine a position of an alignment mark on a substrate and the support structure is configured to support the sensor system. The sensing element is configured to detect an unintentional displacement of the support structure and the position measurement system is configured to measure the unintentional displacement relative to a reference element based on the detected unintentional displacement. The athermal interface is configured to prevent detection of temperature induced displacement of the support structure by the sensing element.

Abstract: A new deformable container is disclosed, suitable for use in packaging items of different dimensions. In use, portions of the container are deformed to provide abutments at the interior of the container for fixing therein the relative position of the items of different dimensions. The container is generally rectangular and is made of sheet material, for example, cardboard. In the preferred form, the container is used in conjunction with a detachable cover and with such cover forms a closed rectangular box. When the cover is detached from the container, two pairs of tabs are exposed. These pairs of tabs are located respectively at opposite longitudinal ends of the container. One tab in each pair is coplanar with and hingedly connected to the front wall of the container while the other tab of each pair is hingedly connected to and coplanar with the corresponding side wall of the container.

Abstract: The invention relates to a new and novel synthesis of prostaglandin E.sub.2, and it particularly relates to a novel process starting with relatively inexpensive starting materials. The invention further relates to a synthesis which is readily adaptable for large scale processing because of the high yields in the individual reaction steps.The invention further relates to novel compounds formed as intermediates in the synthesis of prostaglandin E.sub.2. The invention still further relates to synthetic analogs and known metabolites of prostaglandin E.sub.2 and prostaglandin E.sub.1, useful as standards in certain biological assays for determining prostaglandin-like activity.
