Abstract: An animal-resistant optical fiber cable (20) includes a core (22) which comprises a transmission medium and a sheath system. The sheath system includes an outer jacket (65) and a dielectric armor (40) in the form of a shell. The shell comprises a plurality of longitudinally extending preformed segments (42--42) each having an arcuately shaped cross section transverse to a longitudinal axis of the cable and each comprising glass fibers embedded in a matrix material. Each of the segments covers less than half of the periphery of the core and, in a preferred embodiment, eight segments are used. Further, the shell segments are stranded helically about the core with longitudinal edge surfaces of adjacent segments being in engagement with each other. The shell segments not only provide rodent protection for the cable, but also they provide suitable tensile and compressive strength. Further, because the cable has an all-dielectric sheath system, it is inherently lightning, corrosion and EMP resistant.

Abstract: Apparatus for loading components into a component insertion machine. The aratus comprises structure releasably mounted on component magazine loading apparatus to retain components in component magazines received by and aligned in the component magazine loading apparatus. The structure is removable after installation of the component loading apparatus on the component insertion machine to enable components to be selected by the component insertion machine from the component magazines.

Abstract: An improvement in silicon wafer flatness is obtained by reducing the time spent in polishing the wafer. After a conventional lapping operation, the wafer is coated with an etch resistant coating, typically silicon nitride. A polishing step removes the nitride coating on the flat surfaces of the wafer, but leaves a nitride coating on the sides of pits that are formed in the lapping operation. The wafer is then etched, typically in KOH, to remove the silicon surface to below the depth of the pits. The undercutting of the nitride coating removes the pits, or leaves relatively small protrusions in their place. The protrusions may be removed by a short polishing operation. Other wafer types and etch-resistant materials are possible. Integrated circuits are typically formed on the wafers by lithography techniques that advantageously utilize the improved flatness.

Abstract: A redundant (multiple) bus system for interconnecting a plurality of data source and destination entities and arranged to direct data communications over an alternative bus in the event that a prior call to a destination over a first bus was unsuccessful. Each source entity maintains a table designating a separate logical path over each bus to each destination entity, marking each path designation in accordance with the success or failure of calls directed through the path. The bus selection for delivering a communication to any destination is determined in accordance with designation markings for the paths to the destination and independent of designation markings for paths to other destinations whereby a bus may be selected for a delivery to one destination even though prior deliveries over the bus to other destinations have failed.

Abstract: A method for forming articles which include silica-containing glass bodies, as well as the resulting articles, are disclosed. In accordance with the method, silica-containing gel particles are fused to form a glass body. In contrast to previous such methods, these particles are formed by mechanically, substantially uniformly subdividing either a substantially cohesive gel body, or an ungelled or partially gelled sol capable of yielding a substantially cohesive gel body, to form substantially uniformly sized, wet gel particles. Significantly, only substantially cohesive gel bodies which are also substantially elastic are useful in the invention, i.e., mechanical subdivision of non-elastic gel bodies results in these bodies undergoing plastic flow to yield non-particulate, pasty masses.

Abstract: A memory matrix for storing control words for controlling a common control time division multiplexed (TDM) switch is formed by employing a plurality of shift registers connected in recirculating configuration. Synchronization of control word time slots in the memory matrix to system timing is realized by storing a timing marker which is advanced in identical manner as the control word time slots. If synchronization between the system timing and control word time slots is interrupted, it is restored by controllably inhibiting advancing of the control word time slots and the stored timing marker.

Abstract: Group III-V compound MISFETs include a low-doped diffusion barrier layer disposed between a source/drain contact-facilitating layer and the channel layer.

Abstract: An ultraviolet screening agent can be incorporated into a preformed silicone rubber intraocular lens by bringing it into contact with a solution which contains the agent in a higher concentration than the lens material.

Abstract: An automatic gain control circuit for an amplifier operating over a prescribed frequency range detects the output level of the amplifier; and couples a repeated predetermined waveform occurring at a rate greater than the reciprocal of twice the upper frequency of the prescribed frequency range to the output level signal. The waveform varying level signal is compared to a reference threshold to control the gain of the amplifier through a switched resistive elemement in the amplifier feedback path. The repeated waveform variations about the amplifier output level causes the value of the switched resistance to vary as a function of the output level. A low pass filter connected to the amplifier output removes switching transients resulting from the high frequency changes in the switched resistive element. The gains of a plurality of amplifiers may be determined by a common control for accurate tracking over a wide dynamic range.

Abstract: The ultraviolet screening of a silicone rubber intraocular lens can be enhanced by the addition of an optical brightener. The optical brightener also serves to reduce any apparent yellow tint that may occur. The optical brightener is incorporated into the preformed silicone lens by immersing it in a solution containing the optical brightener and an ultraviolet screening agent.

Abstract: Decoding unit for CMI-encoded input signals. A signal having 0/1 transitions is first derived from a signal. A 0/1 transition occurs in a CMI-signal as the result of encoding a binary zero or two consecutive binary ones. In the latter case the 0/1 transition is preceded two bits earlier by a 1/0 transition. By deriving a signal having 1/0 transitions, delaying this signal by two bit intervals and by comparing it to the first signal, the 0/1 transitions corresponding to a binary zero are then accurately detected. The resultant signal can easily be extended by one bit period, so that independent of any phase inversions of the read clock, the appropriate binary information is always generated.

Abstract: A high resolution image is decomposed into a low resolution replica and into corresponding supplemental information for facsimile transmission to a remote location. The low resolution replica is generated by replacing a super pixel (picture element) including a plurality of high resolution image pixels with a single low resolution pixel and corresponding supplemental information, if any is required. The pixels of the low resolution replica are chosen such that all supplemental information required to convert the low resolution replica back to the original high resolution image is located at the "edges " of the low resolution replica. Thus, if a low resolution pixel is at an edge in the low resolution pixel is at an edge in the low resolution replica, supplemental information is generated in accordance with prescribed criteria.

Abstract: A method and apparatus for processing calls to a directory number, shared by a multiple number of terminals, in which a switching system selects a preferred terminal for serving the call based on call answering activity. The switching system establishes a connection to the preferred terminal. This system connection is for use in answering the call at the preferred terminal. Although the system connection is established to the preferred terminal, all the terminals sharing the directory number are enabled to answer the call. The arrangement dynamically selects the preferred terminal rather than establishing an initial system connection to only a statically defined terminal.

Abstract: A multilayer ceramic package for optical devices is disclosed for use in both high and low bit rate applications. A side portion of the multilayer package is formed to provide a multilayer microwave input connection for a high bit rate signal. In an exemplary arrangement, an intermediate ceramic layer of the multilayer structure is defined with an appropriate thickness and metallized on areas of the top and bottom surfaces. This combination thus forms a multilayer microwave connection defined as a microstrip. Other multilayer configurations, for example, a stripline, may also be used. By utilizing a multilayer microwave connection in place of a conventional electrical connection, the impedance of the high frequency input source can be better matched to the optical device.

Abstract: A cable (20) which is particularly suited to the transmission of substantially error-free data at relatively high rates over relatively long distances includes at least two pairs of individually insulated conductors (42--42). The pairs of individually insulated conductors are enclosed in a tubular member (51) comprising a plastic material. A metallic shield (54) may or may not enclose the tubular member, and in a preferred embodiment, a plastic jacket (58) is provided. The twist length of each pair of insulated conductors does not exceed a value equal to the product of about forty and the outer diameter of the plastic insulation. Further, the twist lengths among the conductor pairs are varied in accordance with a twist frequency scheme modulated by non-uniform increments of twist frequency.

Abstract: Multiple copies of sheets produced by a copying machine or the like are sorted onto trays. The trays are arranged in a stack and are moved upwardly and downwardly to enable different sheets to be sorted onto the trays on each upward pass and downward pass of the stack. The trays have pairs of pins extending outwardly from opposite side edges into a pair of slots on upright support plates. The walls of these slots support each tray as a cantilever. One of the slots, which is closest the rear edge of the trays, is preferably larger than the other and enables any adjacent trays to be spread apart by lifting and tilting one of the trays so as to provide access between the separated trays for jam clearance and the like. A shifting mechanism moves the trays across a gap into which sheets are dispensed from the copier onto the tray at the underside of the gap. This lifting mechanism is a rotatable assembly which engages the pins and moves a tray across the gap.

Abstract: A connector body (26) which terminates at least one transmission medium includes on each side thereof a cantilevered arm (66) having a latching nub (70) projecting from a free end of the arm. A release cover (80) having a gripping portion (88) oriented toward a cable input end (32) of the connector body is mounted slidably on the connector body with the latching nubs of the arms each projecting through a window (90) in the cover. Conductors in the connector body are connected to conductors of another connector or of a device by inserting the connector body and release cover into a coupling (100) or into a receptacle. The latching nubs of the arms protrude into openings (106--106) provided in a housing (102) of the coupling to secure the connector body thereto. In order to withdraw the connector body from the coupling, a user moves the cover slidably along the connector body toward the cable input end.

Abstract: Oxypricin, an antibiotic of the Formula (II) ##STR1## having antibiotic activity is disclosed.

Abstract: A call coverage arrangement in which coverage personnel are informed of the switch-hook status of covered terminals by way of a single two-part indicator on the coverage terminal. The two-part indicator indicates switch-hook status for any one of a number of covered terminals. The first part of the indicator identifies the covered terminal and the second part defines the switch-hook status of the identified terminal. The arrangement is flexible in providing coverage for additional terminals and in providing coverage via forwarding from any termianl, since there is no need to assign and dedicate status indicators to particular terminals.

Abstract: By adjusting the AC field conditions, i.e., by grounding the environment of a substrate being etched with a chlorine-containing plasma, a significant increase in etch selectivity is achieved. By applying a similar AC field adjustment to the reaction chamber surfaces, excellent etch uniformity is achieved in conjunction with excellent selectivity.
