Abstract: A textile substrate is patterned by the selective application of various dyes to the substrate surface in a way that provides desirable, visually apparent enhancements in the area of pattern detail, definition, and color range, through the use of a novel patterning system, including the application of various chemical agents, that makes such enhancements possible. In one embodiment, the patterning system described herein is capable of producing pile-faced textile substrates, useful as floor coverings, that exhibit a unique combination of desirable pattern attributes that have been identified and measured using novel techniques specifically developed for these substrates and pattern attributes.

Abstract: The present invention is directed to an apparatus and process for precisely measuring the position of a deflector blade. When patterned dyeing a moving textile web wherein continuously flowing streams of liquid normally directed in paths to impinge upon the web are selectively deflected from contact with the web in accordance with pattern information then each continuously flowing liquid stream is selectively deflected by a stream of air which is discharged, in accordance with pattern information, from an air outlet located adjacent each liquid discharge outlet. The air outlet is positioned to direct the air stream into intersecting relation with the liquid stream and to deflect the liquid into a collection chamber or trough for recirculation.

Abstract: An improved mechanism for securing a parison molding cone atop the plunger shaft of a glass container-moulding machine. A one piece collar is secured to the head of the shaft by a bayonet tongue-and-groove assembly. The collar has a crenulated inwardly projecting flange around its upper rim. The base of the molding cone has an outwardly projecting crenulated flange around its lower rim. The flanges of each part are shaped and dimensioned to mesh together, thus allowing the flanged part of the base to be inserted into the top section on the collar then rotated into a locking position. Two spring-loaded locking members mounted into the collar engage recesses in the flange of the molding cone in order to prevent rotation of the molding cone away from its engaged position. A locking pin located in a vertical channel in the collar when forced down by the cone engages a recess or groove in the shaft and is locked there permanently by the cone while it remains in its engaged position.

Abstract: An apparatus and method for alleviating the foam associated with the application of dyes or other liquids to moving textile materials, such as pile carpets, fabrics and the like. This invention may be used with machines in which arrays of individual streams of liquid dye are used to pattern substrates. There is a means for alleviating the foam created in the fluid stream utilized to treat the textile substrate.

Abstract: A method and apparatus for patterning a substrate wherein liquid unfixed dye is applied to the substrate in the form of a spray. One or more streams of pressurized gas such as air are then directed onto the substrate for the purpose of displacing some of the unfixed dye where the streams impinge the substrate, thereby causing a visually distinctive area on the substrate where the relative dye concentration is reduced. Resulting products are also disclosed.

Abstract: A method and apparatus for dyeing a substrate using an array of spray generators. In a preferred embodiment, each spray generator is comprised of a gas port from which an intermittent jet of pressurized gas is directed onto the substrate to be dyed. Positioned along the path of the gas jet is a nozzle from which continuously flows a liquid dye. When dyeing is desired, i.e., in response to pattern data, the gas jet is rapidly cycled on and off, thereby atmoizing the dye emerging from the nozzle and establishing discrete bursts of spray which meter a controlled quantity of dye onto the substrate. When the gas jet is interrupted, the nozzle projects an interrupted stream of liquid dye which does not contact the substrate.

Abstract: A telephone switching system for telephone trunk and subscriber lines that carry voice and associated supervisory information signals. The voice signals are received through one of a plurality of ports under the control of a port event processor, and are transferred through a switching arrangement under the control of a call processor for transmission through a second port. The supervisory information is received with the associated voice signals, and is sampled and stored in a port data store memory. The call processor can retrieve or modify the supervisory information stored in the port data memory store, and can store control information in the port data store. The port event processor enables the transfer of certain supervisory information from the port data store for transmission with the associated voice signals to the respective port. The port event processor also performs certain operations specified by the commands and supervisory information stored in the port data store memory.

Abstract: An adjustable transceiver antenna mount in which the force required for adjustment is such as to facilitate one-hand operation, enabling the driver to adjust the antenna position from the driver's seat. With internal controls, the driver is able to do so without even opening the window. The mount has a releasable positive locking action and also a serially arranged fail-safe friction connection. The mount provides for connection of the coax cable to a fixed component of the mount to eliminate cable flexing. The mount provides a sealed housing for the connection. The mount provides embracing electrical contact elements for a main shaft. These are pressed against the shaft by a compression spring arrangement which also urge releasable antenna locking members to remain in engagement. The mount has other features recited in the body of the specification.

Abstract: A common control for a community office (C.O.) switching system includes two interactive processors. One of these interactive processors is a call control processor which comprises the uppermost element in the control hierarchy. It is a stored program processor and its functions include: (i) control of call progression, (ii) marking paths through the matrix switch network, and translations. The other of these interactive processors is a port event processor. It is a construction of electronic logic circuitry known as "combinatorial logic". The port event processor operates on the principle of the combinatorial logic being sequentially coupled to every one of the port equipment positions over a 4 millisecond scan cycle. A pair of functional units of the port event processor provide the common control capability to sense or transmit supervisory events.

Abstract: A telephone switching system for telephone lines in a telephone network that carry voice and associated supervisory information signals. The voice signals are received through one of a plurality of ports under the control of a port event processor and are transferred through a switching arrangement, under the control of a call processor, and transmitted through a port again under the control of the port event processor. The received supervisory information is stored in a port data store memory, which also stores call state and command information. The port event processor retrieves the stored supervisory information and commands from the port data store memory, and processes the supervisory information in response to the commands in at least two functional units, and returns processed information for storage in the port data store memory.

Abstract: A common control for a community office (C.O.) switching system includes two interactive processors. A call control processor comprises the uppermost element in the control hierarchy and is a stored program processor that controls call progression, marks paths through a matrix switch network, and performs other functions. A port event processor constructed of "combinatorial logic" is sequentially coupled to every port equipment position connected thereto over a four millisecond scan cycle. Interaction between the call control processor and the port event processor is effected through a port data store, which provides an individual port data file per port equipment position. The port event processor also includes timers that respond to call timing information that can be stored in a port data field for controlling the processing of certain signals from the corresponding port equipment position.

To eliminate periodic clogging of the dye jets they are periodically washed by directing a stream of liquid into the dye jet orifices under sufficient pressure to counteract the dye liquor jet action to dislodge and remove contaminants from said orifices.
