Abstract: An improved probe cover and thermometer for tympanic temperature measurement include means to preclude the reuse of a probe cover. In the preferred embodiment, a cup-shaped probe cover includes two or more legs terminating in tabs or flanges. The tabs or flanges are sensed by switches. In the preferred embodiment, the switches are disposed within a recess, thereby precluding the circumvention of the switch function. In an alternative embodiment, a plurality of externally located switches are provided to mate with a plurality of flanges. Alternative, the extension from the probe cover may comprise a skirt terminating in a flange or tab. In operation, the thermometer may not be operated without the positive presence of a probe cover, as indicated by the presence of the tabs acting upon the recessed switch or a plurality of tabs acting upon the externally located switches. Ejection of the probe cover causes deformation of the probe cover to indicate prior use.

Abstract: A two bulb mercury vapor lamp apparatus includes a housing with a bottom whose cross-section forms a curved "M" shape. A pair of reflectors are attached to the bottom of the housing with each reflector positioned in one-half of the "m". The reflectors direct light from the bulbs onto a focal plane where a photosensitive material is located. A plurality of quartz liquid coolant circulating tubes are positioned between the bulbs and the photosensitive material which tubes both cool the lamp and filter out infrared rays. The coolant tubes are attached to a pair of end blocks which are removably secured to the housing. The end blocks, connected plumbing lines and coolant tubes can be lowered from the housing intact, thus greatly facilitating maintenance access to the bulbs and reflectors.

Abstract: A radiant drying system includes a radiant energy source such as a lamphead with a mercury vapor lamp which produces radiation in the infrared and ultraviolet spectral ranges. Water-filled tubes extend through the lamphead below the lamp for filtering some of the infrared radiation. A housing or filter assembly is mounted on the bottom of the lamphead and includes downwardly-diverging walls and a bottom enclosed by a light-transmitting lens, which filters the ultraviolet radiation to reduce the output thereof in the "B" (beta) range. A fluid system circulates water through the lamphead and air through the housing assembly.

Abstract: A heat lamp assembly is provided which includes a housing with a pair of quartz tube, infrared heat lamps mounted therein. A pair of reflectors partially enclose the heat lamps ad include extension legs which project downwardly from the housing and partially under the respective heat lamps. The heat lamp assembly is mounted on a printing press which includes a delivery area for a stack of printed sheets and a structure partially overhanging the delivery area. The reflector extension legs extend in an upstream direction with respect to the printing press whereby those areas of the printed sheets underneath the overhanging structure receive infrared radiation from the heat lamps.

Abstract: A tensioner assembly pre-stretches a film web prior to unitizing a pallet load. The film web undergoes three stages of stretching by the tensioner assembly which includes two driven rollers and a resiliently biased dancer roller. The dancer roller engages the film and maintains it under continuous tension loading as the pallet load rotates. An electrical control signal proportional to the angular position of the dancer roller is employed by a control circuit to vary the rotational speed of the pretensioner drive rollers. The film web is stretched in a first stage between a feedstock roll and the first drive roller. A second stage of stretching occurs between the first driven roller and the second driven roller. Finally, the film web undergoes a third stage of stretching between the second driven roller and the pallet load, with the web being maintained under tension at all times by the resiliently biased dancer roller.

Abstract: An elongated, resilient member such as a coiled spring or a belt of elastic material is disposed in lapping engagement with first and second drive rollers for engaging and threading a web around the rollers in response to rotation of the rollers. The drive rollers are rotated in opposite directions and the belt or spring is disposed in a twist, thereby defining a figure "8" lapping pattern. In a preferred embodiment, each roller is circumscribed by a groove in which the spring or belt is reeved.

Abstract: The apparatus employs two or more beams of radiation of different spectral composition which are transmitted through a sample and received by a detector which provides signals for computing the required parameter by ratio measurements. The beams are directed to a sample zone where a part is transmitted through, and a part is reflected by a sample. The invention provides diffusing means to receive the transmitted and reflected parts and pass the same onto a radiation responsive detector. The diffusing means may be a ground glass plate or a member made of fused alumina. A concave mirror may be used to reflect the reflected part back through the sample zone which is close to or at the center of curvature of the mirror. A beamsplitter may also be used so that the beams are directed substantially normal to a plane in the sample zone.

Abstract: A dryer for removing vaporous substances from products in which the product sequentially passes beneath an array of ventilating nozzles and an array of infrared heaters. The dryer includes a generally rectangular frame forming a central drying zone having an infeed end and an outfeed end. The array of ventilating nozzles is positioned at the infeed end of the drying zone in order to quickly remove surface moisture from the product. The downstream array of infrared heaters removes residual surface moisture and moisture beneath the surface of the product. The ends of the heaters project into a pair of inlet ducts extending along opposite sides of the frame so that the ends of the heaters are cooled by air flowing through the ducts. Air flows through the ducts from an inlet near the outfeed end of drying zone to a blower manifold where the air is mixed with recirculated gases from the ventilating nozzles and air entering the infeed end of the drying zone before being conveyed to the blower.

Abstract: A projector for projecting images of an image bearing film which has marginal edges and a central image bearing portion, comprises a film guide which includes vertically spaced, substantially cylindrical guide members. The image bearing film is guided radially to the periphery of said guide and is passed around the peripheries of the guides with the marginal edges engaged thereon and the image bearing portion disposed between the guides.
