摘要:
A production information reporting/recording system is disclosed herein including a number of features to ensure efficient, flexible and reliable recording of production data in a manufacturing system. Such features include validating the content of event messages to ensure compliance of event report information with a standard. The system also supports caching IDs associated with particular aspects of an event message (e.g., a production request, a process segment) as well as a unique ID corresponding to the ID assigned by the production event database to reduce the need to access the database when assigning unique database IDs to received events. The production event messaging system also supports both asynchronous and synchronous transactional messaging between the sources of events and the production database service. Furthermore, the system supports including extensions to a base production message schema through the inclusion of metadata that designates a particular production server to parse and apply/store the extension information.

A glass adhesion composition containing a copolymer having an acid and a substituted amide, silanol, or amine oxide functionality. The substituted amide, silanol, or amine oxide functionality provide excellent adhesion of the copolymer to glass, silica, sand and other silicon-based substances. The copolymer is useful as a fiberglass binder, and also useful in providing protective coatings on glass sheets. A fiberglass sizing composition is also provided having a copolymer that includes at least one acid group derived from at least one acid monomer, a hydrophobic comonomer, and a crosslinker. Additives can be added to the compositions to provide other functionality such as corrosion inhibitors, hydrophobic additives, additives for reducing leaching of glass, release agents, acids for lowering pH, anti-oxidants/reducing agents, emulsifiers, dyes, pigments, oils, fillers, colorants, curing agents, anti-migration aids, biocides, plasticizers, waxes, anti-foaming agents, coupling agents, thermal stabilizers, flame retardants, enzymes, wetting agents, and lubricants.

The present invention relates to novel catalysts for use with a fiberglass non-woven binder. The catalyst can be a Lewis acid, an organic acid salt, a free-radical generator, or a mixture thereof. The catalyst provides stronger bonding, increased crosslinking density, reduced curing times, and reduced curing temperatures. Fiberglass mats made with polymer binder compositions containing the catalyst exhibit both flexibility and elasticity, allowing the mats to be compressed for storage, yet return to original thickness once the compressive forces are removed. Formaldehyde-free wood composites, such as plywood and fiberboard, may also be produced with polymer binder compositions containing the catalyst.
摘要:
A method and an apparatus for demodulating M-ary PSK signals of the type wherein the modulation is limited to phase transitions between adjacent phase states. The method is operative in a demodulator which comprises a phase splitter dividing a source signal into three paths with a preselected phase relationship among phases, one of the phases being delayed by nominally one bit period, a pair of mixers or multipliers, each one of the mixers receiving as one input a representation of the delayed-phase component and each one of the mixers receiving as a second input a representation of one of the other of the phase components. Combined signals are provided by the mixers to a combiner which adds or subtracts the combined signals according to expected input signal type to produce from one to N intermediate output signals. An intermediate output signal is coupled to a corresponding two-level comparator, each of which receives and responds to the respective intermediate output signals to produce a digital output. Digital logic circuitry responds to the digital outputs of each of the comparators to map the digital outputs into a single digital bit stream of ones and zeroes.

Apparatus utilizing pressurized liquid for testing containers such as soft drink beverage bottles for the ability to withstand internal pressure and for the absence of leakage. The pressurized liquid is introduced into each bottle with a swirling motion through an annular passageway and air is expelled from the bottle through a vent tube positioned coaxially within the passageway. The outer wall of the annular passageway is formed by a resilient sleeve which is compressed radially and extended axially by the pressurized liquid to provide a tight seal with the bottle. Pressure within the bottle is monitored by a sensing member which is displaced by the pressurized liquid and actuates a pivotally mounted lever arm which provides an amplified movement and corresponding to the displacement of the sensing member. In the disclosed embodiment, the apparatus is mounted on a rotary turret, and the introduction of the pressurized liquid and the expulsion of air are controlled by valves which are actuated automatically as the turret rotates between different positions.

A pyramidal horn antenna that decreases ringing in radar systems that are placed against a solid volume of e.g. concrete or wood for finding an object in or behind the solid volume. The antenna includes a solid, pyramid-shaped dielectric, the pyramid shape including a rectangular base and four triangular sides that extend from the base to meet at the apex of the pyramid. Two conductive triangular plates overlay opposite ones of the four sides of the pyramid, each of the plates including an electrical connection for coupling the plate to a radar system. The pyramid-shaped dielectric has a dielectric constant that approximates the dielectric constant of the solid volume, and therefore provides an impedance match between the antenna and the solid volume.
摘要:
A baseband signal is spectrally efficiently transmitted on a broadband transmission medium by inserting gaps in packets of digital data transmitted in a modulated first radio frequency carrier. The transmitted packets of data are received by demodulating the modulated first radio frequency carrier, and the gap is monitored for the presence of digital data thus indicating a collision of simultaneously transmitted packets of digital data. A seed of arbitrary digital bits are used in scrambling each packet of digital data and is transmitted with the packet of data for use in descrambling the data. In retransmitting the packet of data the seed is included. The originally transmitting node receives the retransmitted packet and compares the retransmitted seed with the originally transmitted seed for detecting an error in retransmission.
摘要:
A communication network having a first broadband communications channel or transmitting bus and a second broadband communications channel or receiving bus, wherein the first broadband communications channel passes information upstream to a head end employing an offset quadrature phase shift keyed (OQPSK) modulator in bursts, and the second broadband communications channel passes information downstream from the head end to remote nodes in a continuous bit stream. All nodes of the system are coupled to both the first communications channel and the second communications channel. According to the invention, modulation of signals applied to the first communication channel is optimized for burst communication from a plurality of sources to central control at the head end, and modulation applied to the second communications channel is optimized for continuous communication from the central source to a target node. In one specific embodiment, the communication between the central unit (head end) and any one of a choice of target nodes through the second communication channel is by means of three-level class one partial response AM-PSK modulated onto a carrier, which is optimized for continuous operation.
