Patent CA-1299656-C (CA)
Title: Protection against loss or corruption of data upon switchover of a replicated system
Inventor: KOCAN KRISTIN F
IPC: H04B10/03
Filed: 1989-08-21
Granted: 1992-04-28
Abstract: Abstract In a protection-switching arrangement, each optical output of replicated switching nodes is connected to the input of an error detector and of an optical delay line; their outputs are in turn connected to inputs of an optical AND gate. The error detector generates an error signal when it detects error in data at the connected output. The error signal causes the connected AND gate to block signals incoming from the connected delay line. The delay line is sized to ensure that the connected AND gate, when responding to an error signal, blocks signals whose error status is represented by that responded to error signal. AND gates whose inputs are coupled to like outputs of the switching nodes have their outputs connected to inputs of an optical OR gate. The OR gate combines signals received at its inputs into a single signal at its output. The switching nodes may be replaced by computers, transmission lines, other replicated signal-handling elements.

Abstract: WAVEFRONT VECTOR CORRELATION PROCESSOR      ABSTRACT OF THE DISCLOSURE A wavefront vector correlation  processor (10) for  providing rapid, weighted correlation of a  given vector with other  vectors in a given  vector space.   In one embodiment  the processor  (10) includes  an  interconnected   two-dimensional  array  of   simple processing elements (12) that is an electronic analogue of the X,Y plane.  Each processing element  (12) is connected to  neighboring processing elements (12) and is capable of transmitting a pulse to its neighboring processing elements in response to an input pulse. An initial pulse initiated at  a processing element (12) having  a first classification causes  electronic ripples to  spread out  in chain/reaction among neighboring  processing elements (12).   When the electronic ripple  reaches processing elements  (12) having  a second classification,  a  controller circuit  (24)  senses  these events and measures  the time  between the initial  pulse and  the detected pulse.  This measured  time may then  be used to  provide correlation between  the vector of the  first classification  and vectors having a second classification.

Abstract: ABSTRACT OF THE INVENTION    A combination  log debarking,  log chipping unit having a debarking apparatus and a chipping apparatus mounted on a common chassis, the two apparatus are aligned for conveying logs from the debarking  apparatus to the chipping  apparatus.   The  two apparatus are separated by a space of about 6-10 feet to permit loose bark to be removed from the logs and thereby avoid bark contamination of the chip.   A conveyor system between the two apparatus guides and conveys logs to the chipper.  A single power source enables control over the feeding of the logs to synchronize log feeding with the chipper's chipping capability.   A loader over the debarking apparatus provides convenient loading of the logs into the debarker.  The power source and controls for the various operating components are all under the common control of the loader operator.

Abstract: In the substantially radially extending compartments of a cell wheel or drum of a processing apparatus for processing printed products, there are inserted removable divider or partition walls. The removable divider or partition walls divide each of the compartments into two feed channels. These divider or partition walls terminate at a predetermined distance or spacing from the floor of the compartments. Feed structure, such as grippers for advancing the printed products are arranged in the region of the floor of each compartment and such feed structure commonly coacts with both feed channels. A printed product is inserted into each feed channel. Both printed products are conjointly advanced in the longitudinal direction of the compartments by the related product feed structure and these products are simultaneously opened and furnished with inserts. The opening of the printed products and the stuffing of inserts is done separately. The divider or partition walls can be removed without difficulty, whereby the number of reception spaces or regions (feed channels) for printed products is reduced by one half.

The propellant air is laden with synthetic silica having a BET surface area of at least 25 m<3>/g. With the propellant air, the synthetic silica is introduced into the mass flow of the spray concrete mix in such a quantity that the applied spray concrete undergoes a spontaneous temperature increase by a few degrees Kelvin immediately after the application. A spray gun for the process is also described.

Date Mar. 5, 1992.In an m-of-n computer system, timer signals (TA, TB, TC) are fed as interrupt requests (IA, IB, IC) to modules (BGA, BGB, BGC) allocated to the individual computers and from there to the majority elements (MA, MB, MC), which release appropriate interrupts (INT2A, INT2B, INT2C) to the corresponding computer when the m-of-n condition is adhered to. To be able to recognize, after one computer (for example MCA) has failed, when interrupt requests (IB) of another computer (for example MCB) fail to appear, each remaining operational computer (MCB, MCC) initiates troubleshoot testing programs in larger time intervals. This is achieved by performing OR-gating operations on certain timer signals. Switching through the interrupt requests via the majority elements requires much less time than does a corresponding software-comparison operation and results in only a very slight base load for the computer system during the processing of interrupts.

Abstract: The present disclosure describes flame-retardant, high-temperature resistant polyimide fibers, nonwovens made from said fibers, as well as the fibers and molded articles obtained after a heat treatment. A composite of such fibers is heated to a temperature in the glass transition range of the fiber, i.e. between 280 DEG  and 350 DEG  C. This heat treatment develops a contraction force of 0.3 to 1.1 cN in the fibers which results in a fiber shrinkage of between 20 and 60% and the formation of cohesive bonds. The fibers of the invention enable the manufacture of molded articles that are particularly strong, have a high temperature resistance and flame-retardant properties, while having a relatively low density.

Input and output sections of microstrip conductor are mounted on the surface of the substrate and the sloping surfaces of the ramp members in axial alignment with the rod and ramp members.  A helical coil surrounding the rod and passing through the substrate and ground plane is selectively energized to produce a unidirectional magnetic field along the longitudinal axis of the rod which causes Faraday rotation of RF wave energy passing through the rod from the input microstrip section and subsequent misalignment of the RF wave energy exiting from the rod to the output microstrip conductor section.
