Abstract: A method and apparatus for printing arbitrarily large circuit patterns using small field optics. The use of small field imaging optics allows the use of high NA lens designs capable of printing smaller geometries than otherwise would be possible. The field size in a first axis is extended by scanning an object and image past the lens; the field size in a second axis is extended by stitching the scans together in an overlapped fashion. This overlapped printing technique averages many random and systematic errors and allows the placement of field adjacencies within die boundaries. The effective field size of such a system is limited only by reticle size and stage mechanics. The apparatus further includes error correction loops for enhancing stage synchronization accuracy and for reducing field adjacency errors.

Abstract: A non-halogenated cable for use in an electronic system having a core which includes a transmission medium, the transmission medium being a metallic or optical fiber conductor having thereon an insulating layer of non-halogenated polyethersulfone polymer composition, and a non-halogenated jacket which enclosed the core and the transmission medium, said non-halogenated jacket being a single layer of insulating material.

Abstract: The present invention is for a radiation transmitter which transmits radiation to an illumination spot for forming reflected radiation. The transmitter includes a plurality of radiation transmission sources. Each of the sources transmits to a portion of the illumination spot. The transmitter includes means for alternately activating a portion of the transmission sources to illuminate a portion of the illumination spot for aligning a radiation receiver to receive the reflected radiation.Each resident of network transmits in turn its address and the address of each resident that it recognizes. Once a prospective resident can recognize each resident of the network it announces that it is joining the network and states its new address and the address of each resident it can see. Every resident then amends its list of recognized residents to include the new member.

Abstract: One or more rigid sealing segments are attached to pipe end sections and the assembly lined to form a fluid-resistant joint. A segment surface forms the primary sealing interface of lined pipe sections without the need for a conventional removable liner edge seal. The lining process and configuration sealably bonds the liner to the fluid-resistant sealing segment and to the non-fluid-resistant pipe. The manner of bonding both avoids (or limits) liner stress and covers the non-fluid-resistant material of the pipe. In an alternative embodiment, the sealing segments are engaged at mating threaded surfaces, the mated threads providing a single primary sealing and engagement interface. Redundant liner end sealing may also be accomplished by a sandwiched deformable material if added reliability of sealing harsh fluids is desired. In another embodiment, portions of the rigid sealing segments are slidably mounted relative to each other and the primary seal interface is temperature actuated.

Abstract: The present invention is for an illumination transmitter. The transmitter projects a signal onto a planar reflective surface such as the ceiling of an open office environment. The transmitter includes a plurality of illumination sources positioned in a line wherein the line has a predetermined orientation to the planar surface. The illumination sources are preferably infrared LEDs. The transmitter has means for jointly aiming the illumination sources toward a desired location on the planar surface. The location on the planar surface is usually used to allow multiple transmitters coupled to infrared receivers to allow communication between computers in a LAN. The transmitter also includes means for maintaining the predetermined orientation between the planar surface and the line. The orientation is usually parallel to allow transmitters located large distances from the illumination to project a relatively small illumination spot onto the planar surface.

Abstract: A butt welded and lined flange connector allows the joining of pipe sections lined with a brittle material. Spacing and a sleeved liner at the weld end protects the liner during butt welding. A conventional flange face gasket is modified to protrude into the lined zone to perform a dual sealing function. Like conventional flanged joints, the modified gasket forms a seal sandwiched between the flange interface surfaces. However, departing from current practice, the single gasket also fills the gap and seals the liner edges, protecting the pipe sections from the flowing materials. The invention avoids separate putty-like or elastomeric liner seals as well as exotic liner surface configurations. The present invention is expected to be tolerant of severe conditions and cost effective in many applications.

Abstract: A method for preparing stabilized, rehydratable polyacrylamide gels, wherein the stabilizers employed include substituted monosaccharides where the hydroxyl group of the carbon 1 is substituted with a non-charged group comprising an .alpha.-methyl group or an oligosaccharide having from 2 to about 8 repeating units which can be the same or different. These rehydratable gels can be stored for extended periods of time at ambient temperatures, and can be rehydrated without loss of structural or functional integrity to be used for electrophoretic separation of proteins and nucleic acids.

Abstract: An infrared RS 232 communication link protocol is particularly suited for correcting any errors introduced during a transmission of information. The information is transmitted from a transmitting station to a receiving station. Each of the stations has a control counter each of which toggles between a logic 0 and 1. The control counter for the transmitter and the receiver are phase locked so that all errors may be corrected. The receiver echoes each data bit back to the transmitter which compares the echoed data to the transmitted data. If there is a match, the transmission was successful. If there is no match, the data must be retransmitted. A retransmit control character RTXx is sent to indicate that the receiver should discard the previous character and prepare for a retransmission of the character having the error. Under the proper circumstances and if the counters are still phase locked, the receiver then discards the previously stored character and inverts the counter.

Abstract: A system of localized low velocity laminar air flow in a recirculation path through filtering mechanisms for removing dust mites, waste and other particulate contaminants from the stream of air. That stream of air has a downwardly directed external portion in which a patient's head (particularly its mouth and nose) is adapted to be received.

Abstract: The present invention is for a method for correcting errors in received data during transmission of infrared radiation from a transmitter to a receiver without retransmitting entire packets. The method includes the steps of detecting an error in received data. A negative acknowledgement signal is transmitted from the receiver to the transmitter. A predetermined acknowledgement is transmitted by the transmitter to indicate to the receiver that the negative acknowledgement signal has been received. The data is then retransmitted.The data is transmitted using pulse position modulation. An error is detected by either sensing two pulses within one cycle or sensing no pulses within one cycle.The negative acknowledgement signal comprises transmitting a pulse several positions in duration. The predetermined acknowledgement by the transmitter includes purposely transmitting a cycle containing a known error.

Abstract: A polymer concrete pipe liner is formed from a fluidized, but substantially waterless cement containing mixture applied to the pipe interior. The mixture is composed of inorganic cement particles, a liquid styrene mixture and a minor amount of one or more poly-olefinically unsaturated co-monomers. The mixture substantially excludes acrylonitrile and acrylamide. The co-monomers are preferable selected from a group including trimethylolpropane-trimethacrylate, divinyl benzene, hexadiene, and polyvinylsiloxanes. Mixing the liquid and solid components forms a slurry which is transferred to a pipe interior. Transfer properties can be controlled by particulate gradation, dissolved polymers, and rheology control additives. The pipe is then spun to centrifugally cast the liner. The composition avoids the need for high temperature curing and toxic reactive unsaturates to co-polymerize and cross-link polystyrene.
