Patent EP-0365986-A2 (EP)
Inventor: HUANG MAO YAO
IPC: C08G18/63
Filed: 1989-10-18
Abstract: A method for preparing graft polymer dispersions having broad particle size distribution without wildly fluc­tuating viscosities is disclosed. The method comprises:
     (a) preparing intermediate graft polyol disper­sions containing 30 percent by weight or less solids to achieve a broad distribution of partial sizes in a continuous process by feeding a suffi­cient amount of an ethylenically unsaturated mon­omer and a free radical initiator into a flow re­actor at a temperature sufficient to promote poly­merization, and   (b) charging the intermediate graft polymer dis­persion of (a) to a semi-batch reactor as seeds for further grafting to increase the solids content of the dispersion to above 30 percent by weight by feeding an effective amount of an ethylenically unsaturated monomer and a free radical initiator into the semi-batch reactor at a temperature suf­ficient to promote the growth of the seeds, whereby   the seed particles generally grow larger but retain the characteristic of broad size distribution. The graft polymer so formed is useful in the production of polyurethanes.

Abstract: In a wavelength division switching system having m₁ inlet highways and m₂ outlet highways, m₁ splitters (14) are coupled respectively to the inlet highways to split each multiplex signal into m₂ × n output signals for coupling to respective inputs of m₂ × n optical switches. (15) Each optical switch (15) is responsive to a switching control signal for coupling one of its inputs to one of m₂ × n tunable wavelength filters (16) capable of passing one of n different wavelengths, in response to a wavelength selecting signal, to one of m₂ × n fixed wavelength converters (17) which are organized into m₂ groups. These wavelength converters provide conversion of the input signals so that the converted wavelength is unique in each of the m₂ groups. An array of m₂ combiners (18) are respectively associated with the groups of the fixed wavelength converters and with the outlet highways. Each combiner (18) has n inputs coupled respectively to the outputs of the fixed wavelength converters of the associated group to multiplex signals appearing at the n inputs thereof for coupling to the associated outlet highway.

Abstract: This invention is a method of representing the text in a document in a way that enables very fast text processing on digital computers. More specifically, each word of text is represented as a number (or token) that refers to an information packet describing the word's characteristics. Operations then process each token, rather than each character, to perform text processing functions. In addition to the compact nature of this representation, the performance of virtually all functions in a 'what-you-see-is-what-you-get' (WYSIWYG) editor are improved. In particular, determining line breaks and displaying text are significantly faster when the text is processed a token at a time rather than a character at a time.

Abstract: The reference electrode probe utilizes a metal/metal oxide/ZrO₂ electrode sensor. Metal/metal oxide couples suitable include copper/copper oxide, tin/tin oxide, bismuth/­bismuth oxide, and iron/iron oxide. A zirconia tube (18) has a closed end (20) and an open end (22). The closed end contains the metal/ metal oxide powder (24) and is retained therein by mineral insulation packing (26). A first annular metal sleeve (28) is formed of metal exhibiting a coefficient of thermal expansion compatible with the zirconia tube and has a distal open end (30) in sealing engagement with the open end of said zirconia tube. The first annular metal sleeve (28) also has a proximal open end (32). An insulated first electrical conductor (16) having a distal end in electrical connection with the metal/metal oxide powder extends through the mineral insulation packing and into the first annular   sleeve (28). The first conductor also has a proximal end that terminates near the proximal end of the first annular sleeve. Advantageously, an annular ceramic tube (48) is nested within said first annular metal sleeve and provides the insulation for the first electrical conductor. A signal transfer assembly (14) is sealingly associated with the proximal end of the first annular sleeve. A second electrical conductor (46) passes through the signal transfer assembly (14) to its electrical connection with the first electrical conductor (16). The probe has the ability to withstand powerful radiation fields in high temperature, high pressure water, and constr­uction features which avoid any leakage of the radioactive environment, which the sensor contacts.

Abstract: The invention provides a mass flowmeter for measuring the velocity of a fluid uses an active and a compensating sensor. The sensors (25,27) generate heat when supplied with electrical power. A first heat sink (31) is located a first gap (G) from the first sensor (25) in a direction substantially perpendicular to the direction of fluid flow. A second heat sink (33) located a second gap (GC) from the second sensor (27) in a direction substantially perpendicular to the direction of fluid flow. The dimension of the second gap (GC) is different from the dimension of the first gap (G). Electrical power supplied to the sensors (25,27) causes a thermal flux to flow across the first gap (G) from the first sensor (25) to the first heat sink (31), and causes a thermal flux to flow from the second sensor (27) across the second gap (GC) to the second heat sink (33). A measuring circuit computes the temperature rise of each of the sensors (25,27) when supplied with power over the ambient temperature of the fluid. A computer divides the temperature rise of one of the sensors by the temperature rise of the other of the sensors to determine a ratio. The computer computes from that ratio and the power supplied to each of the sensors, the velocity of the fluid.

Abstract: In a reproduction apparatus outputting copy sheets via exit rollers (14) and stacking the outputted copy sheets adjacent the exit rollers in a stacking tray (18), and which exit rollers are reversible in their direction of rotation to feed selected copy sheets imaged on one side back into the reproduction apparatus in a return path to be reimaged, an actuatable gate system (30) prevents the previously outputted and stacking copy sheets from being recaptured by the reversed rotation exit rollers, by interposing a guide or baffle (32) between the stacking copy sheets and the exit rollers (14) to prevent accidental re-acquisition of copy sheets by the reversed rollers automatically in response to the reversal in direction of rotation of the exit rollers. The guide or baffle (32) preferably comprises commonly rotatably mounted arcuate fingers closely adjacent the exit rollers, which fingers are automatically rotated to extend outside of the periphery of the exit rollers towards the stacking tray in response to the reversal in direction of rotation of the exit rollers. That may be accomplished by camming this finger rotation from an axial shifting of the exit rollers also providing lateral deregistration.

Abstract: An error correction system generates a residue for data symbols encoded in accordance with an (n,k) code which has a distance "d" and a generator polynomial g(x). If the residue contains fewer than "T" non-zero symbols, where T < d/2, the data symbols are assumed to be error free. If there are T or more non-zero symbols, the data symbols are assumed to contain errors and the residue symbols are manipulated to correct the errors, if possible. The residue symbols are thus encoded using an encoder constructed in accordance with the generator polynomial g(x) by loading the residue symbols and shifting the encoder "m" times, where m is a factor of k. The number of non-zero symbols are then counted. If there are fewer than T non-zero symbols in the encoded residue, the encoded symbols are combined with the corresponding symbols in the code word. Thus the first encoded residue symbol is combined with the m th  code word symbol, the second residue symbol is combined with the m+1 st  code word symbol, et cetera. If there are more than T non-zero symbols, the residue symbols are again encoded by shifting the encoder another m times, and so forth. The encoder may include feedback paths which allow it to encode the symbols in one shift the equivalent of i shifts of a conventional encoder, where i < m. Each feedback path includes multipliers which are associated with the expression x r-i+j  modulo g(x), where r is the number of residue symbols and        j = 1,2...,i.
