Abstract: A CATV system uses a single single-mode optical fiber for transmitting a composite optical signal containing television signals in different frequency channels for a plurality of subscriber terminals from a headend terminal to a distribution terminal, and converts the transmitted signals at the distribution terminal into electrical signals for distribution to a plurality of subscriber terminals over a plurality of coaxial cables. The distribution terminal further receives electrical service request signals from each of the plurality of subscriber terminals, and convert each received service request signal into an optical service requestsignal for transmission to the headend terminal over the same single-mode optical fiber as used from transmitting the composite optical signal. Wavelength-division multiplexer/demultiplexers couple the optical fiber to the headend terminal and the distribution terminal to enable bidirectional transmission. The subscriber terminal is responsive to a control signal transmitted to the subscriber terminal for enabling a receiver therein to receive television signals transmitted to the subscriber terminal over a selected one of said different given frequency channels. The headend terminal includes a digital switch that is operated in coordination with the control signals that are transmitted to the subscriber terminals for enabling reception of only selected frequency channels in the respective subscriber terminals, by frequency positioning the television signal indicated by the service request signal received from a given subscriber terminal within the composite signal for transmission to the given subscriber terminal over the given frequency channel enabled by the control signal that is transmitted to the given subscriber terminal.

Title: Melting glass with oxidation control and lowered emissions
Inventor: KNAVISH LEONARD A
IPC: C03B5/173
Filed: 1991-04-05
Granted: 1995-03-21
Abstract: Premature dissociation of fining agent is avoided in a glass melting operation while controlling the final redox state of the product glass by initiating the melting process under relatively oxidizing conditions and subsequently altering the redox conditions to make the glass more reducing.  A glass that is more reduced than usual can thereby be produced without sacrificing the ability to adequately fine the glass.  For a given redox level, less fining agent need be used, thereby lowering emissions from the melting operation, because dissociation of the fining agent is delayed until a later stage of the process where the redox conditions are changed.

Title: Connector attachment component
Inventor: TAKANO TSUNESUKE
IPC: H01R13/00
Filed: 1991-04-11
Granted: 1996-04-16
Abstract: Connector assemblies for electrical components include a base frame having opposing side walls and opposed pairs of interior walls which are disposed parallel to the side walls.          The interior walls define a mounting hole which is sized and configured to receive an individual one of the holders.  The interior walls are interiorly spaced from their respective side walls so as to establish a relief slot therebetween.          The side walls of the base frame are provided with vertically separated locking tabs and mounting flanges.  During mounting of the connector assembly to the supporting structure, the locking tabs will be inwardly resiliently displaced until such time that they each clear the edge which defines the mounting space in the supporting structure for the connector assembly.  At that time, the locking tabs will resiliently return to their "normal" condition.  As a result, the supporting structure will be lockably positioned between the vertically separated locking tabs and mounting flanges.

Abstract: ABSTRACT OF THE DISCLOSURE A diagnostic device detects blood analytes with a sample volume as low as 2 microliters in the hematocrit range of 0% to 60%, or higher. This is accomplished by employing a housing with various chambers and compartments for processing the blood.  A sample application port in the housing is used to introduce blood into a metering chamber.  From the metering chamber, the blood flows to a reaction chamber for analyzing blood analytes.  Blood entering the metering chamber flows into a fluid capillary which indicates that an adequate amount of blood has been received in the metering chamber. The reaction compartment includes a reagent and a filter, the latter of which is disposed between the metering chamber and the reagent so that the reagent reacts with the filtered blood.

Abstract: In a facsimile machine printing received image data on cut sheets that are loaded, cut sheets of different sizes being selectively and exchangeably loaded, a page length determining means, such as a scan line counter, determines the length of each page of the document of which the image data is received.  In the event that the document of which the image data is received contains a page which is longer than the cut sheet being loaded, the image data for that page and any subsequent pages is stored in an image memory, and an alarm is actuated to indicate to the operator the occurrence of a longer page, thereby prompting replacement of the cut sheets with those of a longer size.

Title: Tamper indicating closure having retaining hoop with relief windows
Inventor: HAYES THOMAS H
IPC: B29C57/00
Filed: 1990-08-22
Granted: 1998-12-01
Abstract: A closure (11) for a container (10) has a tamper indicating band (22) with a ban d retainer (29) in the form of an apertured flap or hoop which is hinged to the lower edge (30) of the band. A series of win dows (36) open through the retainer, extending toward but not to its distal edge (32). As the retainer is turned inside out fro m its as-molded position to its use position, its distal and/or outer edges deform to relieve compression and permet the retainer to be i nverted by direct downward pushing force. As a result of the deformation, the retainer in its use position may, depending on th e number and relative size of windows, have an advantageous polygonal peripheral shape rather than a circular shape.

Title: Method for radiation detection and measurement
Inventor: MILLER STEVEN D
IPC: G01T1/105
Filed: 1990-10-31
Granted: 2001-02-13
Abstract: M-center luminescence is used to measure radiation. An LiF crystal (20) is excited with a 442 nm He-Cd laser because absorption measurements in LiF indicate the peak of the M-center absorption occurs at 443 nm. Laser stimulation produces an excited state of the M-center, which undergoes a very strong Stokes' shift.  The peak of the M-center emission spectrum occurs, at 665 nm with a half-width of 0.36 ev. Since the excitation wavelength differs significantly from the emission wavelength, measurement of the deep red emission can be done simultaneously with the excitation. The population of M-centers grows with increasing radiation damage, and therefore M-center luminescence provides a basis for radiation dosimetry.

Title: Method for the production of composite panels based on ornamental stone or an equivalent material
Inventor: MAROCCO GIUSEPPE
IPC: B32B37/00
Filed: 1990-11-26
Granted: 1998-12-22
Abstract: In a first step of the method, a pack (P) of slabs is formed by positioning successive layers constituted by ornamental slabs of stone or equivalent material alternating with supplementary layers constituted by slabs or sheets in succession on a support base (10). A liquid-tight container (C) is then formed around the pack (P). A peripheral space is left in the container (C) at least around the edges of the layers of the pack (P). The interior of the container (C) is then subjected to a vacuum and a settable fluid binder, such as a thermosetting synthetic resin, is introduced into the container whilst it is under vacuum so that the binder fills the whole of the peripheral space, penetrates the gaps between the slabs, and covers the pack of slabs. The vacuum is then released to complete the penetration of the binder and the binder is left, or made, to set so as to produce a consolidated pack of slabs in a block in which the faces of the block corresponding to the edges of the layers are covered by a hermetic covering of binder. The block thus produced is then subjected to final multiple cutting along intermediate planes of some layers to produce one or more composite panels from each zone between two consecutive cuts.
