Abstract: A compact applicator has a two-piece telescoping plunger. The compact applicator, with such telescoping plunger, has a full-size barrel region while maintaining an overall applicator length that is the same and/or slightly shorter than current known compact applicators. In a non-deployed configuration, the inner sleeve of the plunger is generally telescoped within the outer sleeve of the plunger, and the outer sleeve of the plunger is generally telescoped within the applicator barrel.

Abstract: In a self-referencing instrument for measuring electromagnetic radiation, a mounting member to which a sample can be coupled moves the sample such that, in a first position, the electromagnetic radiation impinges on the sample, and, in a second position, the electromagnetic radiation does not impinge on the sample. A detection unit receives the electromagnetic radiation from the sample and generates a sample signal when the sample is in the first position, and the detection unit receives the electromagnetic radiation from the source and generates a reference signal when the sample is in the second position. A processor coupled to the detection unit processes the reference signal and the sample signal. This results in a continuous, accurate reference measurement, and permits the instrument to efficiently compensate for error, while offering accurate measurements.

Abstract: A stationary power tool extension table includes a transparent support plate for positioning against a first side of a built-in table on a stationary power tool. Side plates are connected to an edge of the support plate for positioning against adjacent sides of the built-in table. The support plate is hinged to a frame with an open top and an open bottom. Height adjustable legs are attached to the frame for positioning the support plate level with the built-in table. Slide connectors on the frame and the side plates connect the side plates to the support plate, and enable the side plates to slide horizontally against the sides of the built-in table. A removable tray is supported within the frame by a flange around the bottom of the frame. When the tray is removed, a light may be positioned under the support plate to illuminate a work piece from below.

Abstract: An improved procedure for manufacture of optical replication products comprising the use of a thin amorphous coating of carbon as a protective coating which also facilitates release during replication, between master and replication members. Particular attention is given to controlling the compressive forces of the carbon layer to provide good mechanical coatings on suitable optical surfaces. Thereafter, the replicated members may themselves be coated with the carbon as a protective coating only or for further use as a release-promoting "submasters".

Abstract: Indicia are formed in the surface of an ophthalmic contact lens by sublimating lens material with a high intensity beam of radiation. A beam of light from a laser is directed through one or more cooperating masks having openings defining desired indicia. The light which passes through the masks is directed upon a surface of a contact lens, advantageously near the periphery thereof. By selecting a proper wavelength and controlling the amount of energy directed upon the lens surface the depth of sublimation of lens material can be controlled. In this manner symbols can be formed upon the lens for uniquely identifying it.
