Abstract: A dryer (10) used to remove a flammable solvent or vapors from a traveling web of material (12) or the dryer. The dryer (10) consists of a chamber which is preferably a large metallic cylinder (14) through which the web of material (12) moves longitudinally. Seals (16,18) in the metallic cylinder at the points of entry and exit of the traveling web permit the control system to maintain the desired environment under controlled pressure within the metallic cylinder. The web of material travels successively through one or more zones within the metallic cylinder. At each zone, the web of material is exposed to a pressurized atmosphere which may be at increasingly higher temperatures. The solvent is recovered from the pressurized atmosphere by rapid cooling, membrane separation or absorption. Sensors within each zone measure the oxygen content of the pressurized atmosphere. If the oxygen content exceeds a given threshold, pressurized nitrogen or other inert gas is added. Through the use of a carbon bed (60) at the last zone, the pressurized atmosphere from that zone is rendered sufficiently free of solvent to be exhausted to the air or a nitrogen recovery unit, thereby maintaining the desired overall pressure within the metallic cylinder.

Abstract: A valve control assembly (10) controls the flow rate of a liquid through a solenoid valve (11) by repeatedly opening the valve (11) for a predetermined time. The control assembly (10) includes a timer (30) for providing a pulsed signal having a pulse width proportional to flow rate to energize and deenergize the operating coil (24) to open and close a valve sealing element (20). A nominal delay time is provided between the start time of the pulse and actual movement of the valve element (12). With each pulsed signal, the actual movement time of the valve element (12) is compared to the nominal delay time providing a deviation time. The deviation time is added to the original pulse width to obtain an adjusted pulse width, which when supplied to the operating coil (24), will effectively maintain the valve element (12) consistently open for the predetermined time.

Abstract: An operability or processability evaluating method and apparatus for facilitating design evaluation even by an unskilled user by determining quantitatively and definitely evaluation indexes for article or a part or parts subjected to evaluation and relation between the evaluation index and cost/time involved in operation performed on the article or a part/part. States of the article or a part/part of concern corresponding to the kinds of operations such as processing, assembling or inspection are categorized into a variety of basic elements ( m X) of which the element corresponding to a relatively simple state is defined as a standard element ( m X o ). An index formula is prepared for determining an index ( m ε x ) indicating degree of difficulty of operation by comparing cost ( m C x ) and/or time ( m T x ) involved in operation performed on the basic element ( m X) or an index ( m I x ) thereof with those for the standard element. A program indicating relation between the basic elements ( m X) and the indexes ( m ε x ) is stored in a memory (2). Standard article having predetermined states (m o , a o ,  m ℓ b ) serving as the standard for the article to be evaluated is previously defined. When the cost/time involved in the operation determined in accordance with the index formula in response to the input of the basic elements ( m X) or indexes for the article/part subjected to evaluation by the user increases beyond the cost/time for the standard, an operability evaluation score ( m E i ) indicating difficulty of operation or processing is calculated in accordance with an arithmetic program on the basis of a predetermined evaluation standard value (100) to be subsequently displayed in an evaluation form desired by user.

Abstract: Selective coloring of bi-level latent electrostatic images is obtained through a combination of 1) a scavengeless development nip enabled by an AC biased wire (41,48) in self-spaced contact with a toned donor roll (36,42), 2) a belt image receiver (10) such as either a photoreceptor or electroreceptor without a ground plane and 3) an array of addressable, stationary electrodes (54,56) positioned behind the belt in alignment with the AC biased wire (41,48). Selective coloring of the electrostatic image is obtained by selectively DC biasing addressable, stationary electrode structures forming electrode arrays (54,56) positioned behind the belt (10). By controlling the level and timing for applying a DC bias to each electrode segment, the developability can be switched on and off with x,y addressability in the plane of the electrostatic image. Thus, with a system having resident multi-colored development systems, different areas of the electrostatic image can be developed in a single pass with different colors and perfect registration simply by controlling the DC electrical signals to the electrodes (54,56).

Abstract: An electronic image processing system uses data provided by one or more sensors to perform cooperative computations and improve image recognition performance. A smoothing resistive network, which may comprise an integrated circuit chip, has switching elements connected to each node. The system uses a first sensory output comprising primitives, such as discontinuities or object boundaries, detected by at least a first sensor to define a region for smoothing of a second sensory output comprising at least a second, distinct output of the first sensor or a distinct output of at least a second sensor. A bit pattern for controlling the switches is generated from the detected image discontinuities in the first sensory output. The second sensory output is applied to the resistive network for data smoothing. The switches turned off by the data from the first sensory output define regional boundaries for smoothing of the data provided by the second sensory output. Smoothing operations based on this sensor fusion can proceed without spreading object characteristics beyond the object boundaries.
