Title: Insulation assembly and method for applying adhesive thereto
Inventor: SHAFFER ROY E
IPC: C09J7/21
Filed: 1995-12-27
Abstract: Our unique process applies pressure-sensitive hot melt adhesive to fiberglass insulation with improved adhesion to the insulation surface and the adjoining substrate.

Title: Optical communications network
Inventor: AGUILAR MORALES ANTONIO
IPC: H04B10/272
Filed: 1995-12-29
Abstract: For subscriber access, via optical fibre, to communications networks that offer various types of service by means of an optical access node (AN). The connections between the optical network terminating equipments (ONT), to which the subscribers are connected, and the access node (AN) can be made with point-to-point or point-to-multipoint fibre optic links.      The links between the access node (AN) and the switching centre (CE) are made via optical fibres through which pass the lightwave signals corresponding to a number of subscribers, multiplexed together by means of wavelength division multiplexing. This network permits access to all types of communications services in which each type of service employs a reserved wavelength for its connection between the access node (AN) and the optical network terminating equipment (ONT). This reserved wavelength is fixed and depends only on the type of service.

Abstract: Two dichroic mirrors (26,30) and a dichroic beamsplitter (36) are introduced into the conventional Michelson Fourier transform spectrometer to accommodate two spectral bands. A conventional Michelson Fourier transform spectrometer (FTS) uses two mirrors (20,22), one fixed (20) and the other moving (22). The present invention replaces each of the two mirrors (20,22) with a pair of mirrors, one of which is a di-chroic mirror (26,30). The present invention involves inserting the first dichroic mirror (26) fixed in position between the beamsplitter (12) and the first plane mirror (20) and inserting a second dichroic mirror (30), which can be moved in a direction normal to the plane surface, between the beamsplitter (12) and the second plane mirror (22). The first dichroic mirror (26) and second dichroic mirror (30) transmit long wavelength radiation and reflect short wavelength radiation. A dichroic beamsplitter (36) is also inserted in the interferometer assembly (10) to separate the two spectral bands in the third beam (24). By moving the second plane mirror (22) and the second dichroic mir-ror (30) a different amount to change the optical path difference between the second plane mirror (22) and the beamsplitter (12), and the optical path difference between the second dichroic mirror (30) and the beamsplitter (12), two spectral bands can be proc-essed with different spectral resolutions.

Abstract: A cytological screening system assists a cytotechnologist to determine the presence of "abnormal" cells in a cytological specimen. The system includes a microscope with a motorized stage, autofocus lens, video camera and image capturing and image analysis systems. The specimen is scanned, and cells with characteristics falling outside ranges determined by the system specifically for the specimen are marked for analysis. Analysis is performed by utilizing a set of weighted characteristics, which are based in part of the individual medical history of the patient. Cells with a combination of characteristics which fall outside a predetermined range are determined to be abnormal and are identified for further analysis by the cytotechnologist. Alternatively, the system provides relational information and reference material during the manual screening process.
