Title: Process for the preparation of arylcyclobutene terminated condensation polymers
Inventor: MARKS MAURICE J
IPC: C08G63/00
Filed: 1991-12-17
Abstract: In an improved process condensation polymers having terminal arylcyclobutene moieties are prepared. Such polymers are prepared by adding to a condensation polymerization process one or more arylcyclobutene chain terminating compounds along with the multi-hydric compounds and condensation polymer precursors that are typically employed in such a process. Desirably the condensation polymers have an average degree of polymerization of at least 2, preferably at least 3 based on multi-hydric compound. This process can be used to prepare a range of condensation polymers including polycarbonates, polyesters and polyestercarbonates. The resulting products can be easily processed and shaped into various forms and structures according to the known techniques. During or subsequent to the processing, the polymers can be crosslinked, by exposure to heat or radiation, for example, to provide crosslinked polymer compositions. These compositions have a good combination of properties, including for example, processability into shaped articles having unexpectedly good combinations of toughness, solvent resistance, ignition resistance, modulus and resistance to thermal linear expansion.

Inventor: TAGUCHI TETSU
IPC: H04L27/36
Filed: 1993-06-30
Abstract: In a modulated signal transmission system operable in response to an input digital signal of a baseband to produce a modulated signal through a nonlinear amplifier, a nonlinear converter is controlled by a control signal generator to compensate for not only a nonlinear distortion but also a linear distortion.  The control signal generator is given a difference signal formed by the difference between a linearly-detected signal and the input digital signal and the addition of an estimated linear distortion by a linear filter having filter coefficients controlled by a filter coefficient estimator.  An additional nonlinear converter is located prior to the linear filter.  Alternatively, the linear filter may be located after the nonlinear converter.

Title: Food composition for inhibiting the formation of an intestinal putrefactive product
Inventor: TAKAICHI AKIHISA
IPC: A23L1/09
Filed: 1993-04-02
Abstract: The present invention provides a food composi-tion for inhibiting the formation of an intestinal putrefactive product, containing lactosucrose as an effective component. This food composition is low in calorific value because the lactosucrose is indigesti-ble, and can decrease the amount of an putrefactive product to be generated in intestines. Accordingly, this food composition effectively prevents the out-break of a variety of cancers for which the putrefac-tive product might serve as a promoter.
Patent CA-2113020-A1 (CA)
Inventor: KOBAYASHI SHINYA
IPC: G03G15/01
Filed: 1994-01-07
Abstract: The present invention relates to an electrophotographic color printer which exposes a photosensitive body to form an exposure pattern thereon.  Toner material of two different colors is then applied to the exposure pattern by developers. The toner materials are subsequently transferred to a recording medium and fixed thereon.  The toner materials are applied to the photosensitive body so that each of the two colors of toner materials have regions of two different thicknesses so they will have different thicknesses when applied to the recording medium.  When two of the thicker regions are adjacent, the fixing of the toner materials will cause the toner materials of the two regions to mix.  Thus, if the two adjacent thicker regions are of different colors, a third color will be produced.  Toner material of further colors may also be transferred to the recording medium, by applying further toner materials to the same or another photosensitive body using further developers.

Title: Methods and reagents for diagnosis of autoantibodies
Inventor: HARLEY JOHN B
IPC: C07K19/00
Filed: 1993-04-13
Abstract: A number of octapeptides were generated from the sequences encoding the 60 kDa Ro/SSA peptide, the La/SSB autoantigen, the 70 kD nuclear ribonucleoprotein (nRNP), and the Sm B/B' polypeptide, which represent linear epitopes for autoantibodies present in the sera of SLE and SS patients. These peptides are useful in solid phase assays for patients characterized by the presence of these autoantibodies, and can be used to categorize patients as to the likelihood of developing certain conditions associated with SLE. The peptides are also potentially useful in treatment of these patients using immobilized peptide to remove autoantibody and to block binding of the autoantibodies with patient molecules reactive with the autoantibodies.

Patent CA-2128580-A1 (CA)
Inventor: CASSELMAN BRENDA L
IPC: H04M3/523
Filed: 1994-07-21
Abstract: A system for managing a telemarketing complex is disclosed  wherein  the  probability  of  meeting  a  given performance objective by the agents servicing an automatic call distributor (ACD) within the complex is computed for each subinterval of a predetermined service interval.  This probability is then compared with threshold levels in order to determine whether the ACD requires that calls be shifted to meet the performance objective or whether calls can be accepted by that ACD.   A record is maintained for each subinterval  of  the  probabilities  computed  for  that subinterval and as to whether the system succeeded or failed in achieving the performance objective at the end of the service  interval.   This record is used to compute  the threshold levels used in future comparisons.  In addition, the system computes a line-estimation factor which when multiplied by the number of agents working can be used to estimate the call load for an ACD.

Title: Method and sensor for measuring electric voltages and/or electric field intensities
Inventor: PEIER DIRK
IPC: G01R19/00
Filed: 1993-02-20
Abstract: A method for measuring electric voltages and/or electric fields by the use of a crystal with an electro-optical (Pockels) effect. To this end, in a direction transverse to the direction of propagation (y direction) of a light wave polarized in the z direction, an electric field intensity gradient is generated in the crystal in the direction from which results a corresponding gradient in the refractive index of the crystal. This produces a deflection of the light wave in the crystal which depends upon the field intensity, and on emergence, it is used as a measure for the voltage of field intensity. A suitable sensor for this purpose also is described.

IPC: H02J3/06
Filed: 1994-01-26
Abstract: The method of interconnecting first and second synchronous polyphase AC  networks is for regulating transfer of active power from one of the AC networks to the other. The method involves the steps of for each phase line of the first AC network (a) connecting a first one of a first susceptance to the phase line of the first AC network; (b) connecting a first end of a second susceptance to the phase line of the first AC network; (c) applying to a second end of the first susceptance a first phase voltage derived from the second AC network; and (d) applying to a second end of the second susceptance a second phase voltage derived from the second AC network. the second phase voltage being phase shifted with respect to the first phase, voltage. One of the susceptances is inductive and the other of the susceptances is capacitive. In operation, a phase shift between the first and the second phase voltages forces a regulated transfer of active power from one of the AC networks to the other. These is also provided an interconnecting apparatus for the same purpose.
