Abstract: The present invention provides a process for making an elastomeric web. Generally stated, the process includes moving a first web (26) along an appointed machine-direction (28) of the process, and delivering a plurality of elastomeric strands (30) moving along the machine-direction. The elastomeric strands (30) have been elastomerically stretch to an elongation of at least about 50 percent, and the plurality of elastomeric strands (30) have been laterally distributed along an appointed cross-direction (32) of the process. The elastomeric strands (30) are positioned at a spaced distance (34) from the first web (26), and an adhesive is applied to the elastomeric strands (30) and the first web (26) while the elastomeric strands are at the spaced distance (34) from the first web (26). A second web (36) is laminated to the first web (26) with the elastomeric strands (30) sandwiched between the first and second webs to provide an elastomeric laminate, composite web (24) attached together with the adhesive.

Abstract: A passive rangefinder for determining the range to an object such as an aircraft, rocket or missile which emits electromagnetic radiation makes use of spectral measurements over a broad band of frequencies. The rangefinder includes means 202 for forming a real image of a field of view, spectrophotometer means 201 including an entrance aperture 27 placed to receive at least a part of said real image, dispersion means (15, 28, 29) for separating radiation of different wavelengths and detector means 24 for measuring the spectrum of radiation received from distinct portions of the entrance aperture. The detector output is connected to data processing means 204 arranged to deconvolve the received spectral profile with a stored representation (205) of a range-dependent atmospheric transmission spectral profile to obtain a representation of the spectral emission profile of radiation from the object.

Abstract: An earphone assembly including a bracket member for retaining an earphone unit in place on the head of a user, the bracket member being formed with a channel for receiving a strap of a head gear for mounting the bracket member on the user's head, the bracket member having a shape and configuration for urging the earphone unit into positive engagement with the ear of the user for the efficient transmission of sound thereto.

Abstract: The present invention relates to stethoscopes of the type commonly employed by air line passengers for use with entertaining sound apparatus and is concerned primarily with a stethoscope which may be adjusted for comfort when applied to and suspended from the ear canals of an air line passenger.
