Patent CA-2131621-A1 (CA)
Title: Selective alteration of antibody immunogenicity
Inventor: SYKES THOMAS R
IPC: C07K16/00
Filed: 1993-03-18
Abstract: The present invention relates to a simple process for the modification of, e.g., anti-TAA antibodies, which alters their immunogenicity so that their ability to induce an anti-isotypic response is selectively diminished, while they remain able to elecit an anti-idiotypic response. The latter is of potential immunotherapeutic value, i.e., by activation of the idiotype-anti-idiotype network. This modification takes the form of a controlled and partial reduction of the antibody; effector regions are retained. The invention should permit repeat injections (for diagnosis and therapy) and reduce HAMA interference in serodiagnostic assays.

Title: Secondary filter cleaning method in blood plasma filtration method
Inventor: KAWAMURA AKIO
IPC: A61M1/34
Filed: 1994-01-21
Abstract: ABSTRACT OF THE DISCLOSURE    In a blood plasma filtration method including a primary filtering for separating blood into corpuscule and plasma, and a secondary filtering for cleaning the separated plasma by removing harmful macromolecular substances therefrom, the cleaning of the secondary filter is done by introducing a cleaning liquid the quantity of which corresponds to 5-50 % of the priming volume of the filter into an inner chamber or an outer chamber or both thereof in the filter every time a filtration pressure reaches 70-100 % of the resistible pressure of the filter.  This enables the time required to carry out the filtration of blood plasma to be reduced to about 60 - 70 % of that in a conventional method of this kind, the patient binding hour to be reduced, and the quantity of a cleaning liquid or blood plasma discharged wastefully to the outside of the system to be reduced.

Title: Improved neural semiconductor chip architectures and neural networks incorporated therein
Inventor: PAILLET GUY
IPC: G06V10/764
Filed: 1995-05-16
Abstract: There is disclosed the architecture of a neural semiconductor chip first including a neuron unit comprised of a plurality of neuron circuits fed by different buses transporting data such as the input vector data, set-up parameters, and control signals. Each neuron circuit includes means for generating local result signals of the "fire" type and a local output signal of the distance or category type on respective buses. An OR circuit performs an OR function for all corresponding local result and output signals to generate respective first global result and output signals on respective buses that are merged in an on-chip common communication bus shared by all neuron circuits of the chip. An additional OR function is then performed between all corresponding first global result and output signals to generate second global result and output signals, preferably by dotting on an off-chip common communication bus in the driver block. This latter bus is shared by all the neural chips that are connected thereon to incorporate a neural network of the desired size. In the chip, a multiplexer may select either the first or second global output signal to be reinjected in all neuron circuits of the neural network as a feed-back signal depending on the chip operates in a single or multi-chip environment via a feed-back bus. The feedback signal results of a collective processing of all the local signal.

Abstract: A noise-reduction system for a vehicle wheel assembly which is comprised of a usual rim and a tubeless pneumatic tire having a pair of sidewalls and bead areas mounted  thereon.    A plurality  of  flexible,  non-self-supporting pieces of cloth or other sheet material are attached to the rim or are attached to the bead areas and extend  therebetween,   preferably  at   equally spaced intervals, and form baffles within the annular air chamber of the wheel assembly to reduce noise by changing the characteristics of the sound waves created within the wheel assembly.

Title: High speed media management device
Inventor: TOLLE CHARLES V
IPC: B41J11/42
Filed: 1994-06-08
Abstract: A high speed media management device has tractor means (22) for moving a web (16) through the device past a plurality of work stations at each of which the web may be treated.  Relatively high web tension is maintained throughout its travel path.  Counting means (76) near the beginning of the web path generate a count signal with the passage of each increment of web.  The accumulated count signals are compared to numbers stored in a plurality of registers, each register associated with a work station and each containing a count representative of web travel distance relative to the work station.  The first register count corresponds to the distance required to accelerate the web from a stop.  The remaining registers store that count and a separate count representing the distance between the first station and the corresponding station.  When the counter contents equals the count in a register, an actuating signal initiates a treatment activity at the associated work station.  At predetermined intervals thereafter, additional actuating signals are generated and applied.
