Abstract: A method and apparatus for providing dual energy radiation images of a patient in a kinestatic charge detection system utilizes first and second kinestatic charge detectors commonly connected to apparatus for rotating the detectors about a radiation source at a predetermined velocity. The detectors are adjusted such that ion drift velocity in each detector is equal in magnitude but opposite in direction to the velocity of rotation of the detectors. The radiation from the radiation source is modulated such that relatively low average energy radiation impinging on the patient is received by the first detector and relatively high average energy radiation impinging on the patient is received by the second detector. As the radiation is scanned across the patient and received by the detectors, output data from each detector provides information representative of the intensity of radiation received during the scan. The output data is then combined by a imaging system to form a difference image.

Abstract: Modular web processing units may be physically and electrically assembled into clusters to perform various web processes (e.g. the production of paper forms such as invoices, checks, labels, etc.). Each module has a main process driver which is not directly coupled to a web drive mechanism. Rather, the web drive is program controlled so as to effect the desired web process at controlled displacement intervals along the web. Accordingly, a plurality of successive but different form lengths of depths can be accommodated as the web surface is sequentially processed. A system of such modules can be physically wheeled into position as individual units and electrically connected together by a suitable intermodule bus to rapidly configure a desired overall web finishing process. Examples of modules for unwinding web from a roll, for folding processed web, for printing and for perforation or cut-off are described. Each module has a mechanism driven by a motor for performing an action on the web, an encoder driven by the mechanism and a servo coupled to the motor and encoder, the servo being responsive to signals on the intermodule bus to control the speed of the motor so that the average velocity of the web through the module does not exceed the velocity of the web as it moves through the other modules of the line.

Abstract: A digital subsystem for improving the resolution of a TV digital signal by inserting additional digital samples into the digital TB signal in response to the correspondence of the digital signal and predefined patterns. The digital subsystem is a logic circuit which is responsive to received digital samples to group (502, 504) these digital samples into sets of samples. The digital circuit then calculates (505, 506, 507, 508, 510, 513, 521, 522, 523, 528) the slope between pairs of digital samples of each set and utilizes the calculated slopes to determine the correspondence to the predefined patterns. The determined predefined pattern designates the digital sample to be inserted (503, 520, 524) into each set. The inserted digital sample is either equal to one of the digital samples or the average between two of the digital samples of each set. The calculation of the slopes results in a logical "0" for a constant slope and a logical "1" for a negative or a positive slope. An Exclusive OR gate is utilized to make the determination of whether to use a value equal to one of the digital samples of the set or the average of the value of two of the digital samples. A slope is considered constant if the difference between the pair of digital samples if less than a value calculated from range information of the set of samples.

Abstract: A moderate pressure hydrocracking process in which a highly aromatic, substantially dealkylated feedstock boiling between 149 and 343°C (300°C and 650°F) is processed directly to high octane gasoline by hdrocracking over a catalyst, preferably comprising a large pore size, crystalline alumino-silicate zeolite hydrocracking catalyst such as zeolite Y together with a hydrogenation-­dehydrogenation component. The feedstock which is preferably a light cut light cycle oil has an aromatic content of at least 50, usually at least 60 wt % and a density of at least 0.93 g/cc (an API gravity not more than 25). The hydrocracking typically operates at 4200-7000 kPa (600-1000 psig) at moderate to high conversion levels to maximize the production of monocyclic aromatics which provide the requisite octane value to the product gasoline.

IPC: H04N19/61
Filed: 1987-12-07
Abstract: A video codec is used to reduce the bandwidth of a video signal for storage and/or transmission. To transmit an uncoded quality colour NTSC television signal in digitized form requires channel bandwidth typically 90-130 Mb/s for the signal in the composite format and 216 Mb/s for the signal in the component format. The proposed video codec achieves a reduction of the required transmission bandwidth by a factor of 2-3 by splitting the input signal into two channels, a main and a complementary channel, and by applying different coding techniques in each. In the main channel the input signal is subsampled and DPCM encoded using a fixed-rate companded quantization, whereas VWL and block coding is used to encode the complementary channel carrying the interpolation error signal. This arrangement seeks to ensure high picture quality while being easily adaptable to different transmission rates and signal formats. In bandwidth-on-demand applications the main channel can be used alone to provide a lesser quality signal, for example CATV quality at 35 Mb/s, with an attendant reduction in system complexity.

Abstract: Known supporting and pull-out devices have a multiplicity of individual parts for pulling out the two plates, with the result that the device is of complex construction. Furthermore, the individual parts are visible from the outside and thereby exposed to the risk of soiling and damage. In order to simplify the design of the device and to protect the individual parts optimally, the plates (1, 2) are provided on their two side edges (21', 48) with a panelling (9, 28, 28'), which panellings are in engagement via a carrier (27). When the one plate (1) is pushed in and pulled out, its panelling (9) interacts with a lifting member (8') of the device. The panelling (9, 28, 28') of the two plates (1, 2) fulfils several functions since a positive connection of the plates (1, 2) is achieved due to both panellings (9, 28, 28') when the plates (1, 2) are pulled out. At the same time, the panelling (9, 9') of the one plate (1) serves for lifting and lowering said plate (1). The panellings (9, 28, 28') also protect the plates (1, 2) from wear and damage and allow a constructionally simple design of the device from few individual parts. <IMAGE>

Abstract: An assembly (10) for separating, metering and delivering fluids includes a central rotating member (12) rotatable about a fixed spin axis (14). A processing chamber holding member is connected to the central rotating member (12) by a centrifugally actuated frame (30). At rotational speeds below a first predetermined speed, the centrifugally actuated frame (30) is in a first position. At rotational speeds greater than the first speed, centrifugal force moves the frame (30) to a second position angularly spaced from and at greater distance from the spin axis (14) than the first position. A processing chamber (60) is mounted on the holding member (26, 28) and its orientation relative to the spin axis (14) is the same in the first and second positions. Fluid is provided in the processing chamber (60). By accelerating the processing chamber (60) to the first predetermined speed and decelerating below the first predetermined speed in a selected sequence, specific centrifugal force vectors are generated in the processing chamber (60) that move the fluid (70) and retain it in selected chambers (90, 96, 104, 120). During this sequence, the fluid (70) is metered, separated and delivered to a reduction area (138) where measuring is performed.
