Patent CA-2028643-A1 (CA)
Inventor: BECKER RAINER
IPC: A23F5/04
Filed: 1990-10-26
Abstract: The quality of Robusta coffee is increased by treating raw Robusta coffee beans whose water content has been increased to about 30% to 45% with steam at about 135 DEG  C. to 140 DEG  C. and at a pressure ranging from 3 bar to 4 bar approx. for 60 min to 120 min. This treatment particularly removes the substance responsible for the "earthy" and "musty" aroma note of Robusta coffee, namely the compound 2-methylisoborneol. After the treatment, the beans are processed and roasted in the customary way.

Title: Plastic film metal foil multi-laminates
Inventor: SCHIRMER HENRY G
IPC: B32B7/02
Filed: 1990-11-20
Abstract: A plurality of corona-treated polymeric films, and metal foils or sheets, are alternately arranged and laminated together to form a laminate suitable for e.g. insulating panels. Construction of this absolute or near-absolute barrier can be simultaneous or sequential. The metal foils may be of the same type, or may differ. Aluminum and steel are preferred metal foils. At sufficient thicknesses, the sheet can be stamped or shaped. Both outermost surfaces of the laminate can comprise polymeric film, or both surfaces can comprise metal foils. Alternatively, one outer surface can be a polymeric film and the other outer surface can be a metal foil.

Title: Fault-tolerant computer system with online reintegration and shutdown/restart
Inventor: JEWETT DOUGLAS E
IPC: G06F11/10
Filed: 1990-12-12
Abstract: FAULT-TOLERANT COMPUTER SYSTEM WITH ONLINE REINTEGRATION AND SHUTDOWN/RESTART   ABSTRACT:     A computer system in a fault-tolerant configuration employs multiple identical CPUs executing the same instruction stream, with multiple, identical memory modules in the address space of the CPUs storing duplicates of the same data. The system detects faults in the CPUs and memory modules, and places a faulty unit of offline while continuing to operate using the good units. The faulty unit can be replaced and reintegrated into the system without shutdown. The computer system employs a power supply system including a battery backup so that upon AC power failure the system can execute an orderly shutdown, saving state to disk. A restart procedure restores the state existing at the time of power failure if the AC power has been restored by the time the shutdown is completed. The system employs a pseudo-filesystem to dynamically manage the hardware components. A directory which appears as a standard, hierarchical directory in this filesystem contains a file for each component; each file maps to either a hardware component or a software module. The pseudo-filesystem hierarchy is determined during system initialization and is automatically updated whenever the software or hardware configuration changes. The pseudo-filesystem, called /config filesystem herein, is implemented as a Unix filesystem in the Unix filesystem switch. The multiple CPUs are loosely synchronized, as by detecting events such as memory references and stalling any CPU ahead of others until all execute the function simultaneously; interrupts can be synchronized by ensuring that all CPUs implement the interrupt at the same point in their instruction stream. Memory references via the separate CPU-to-memory busses are voted at the three separate ports of each of the memory modules. I/O functions are implemented using two identical I/O busses, each of which is separately coupled to only one of the memory modules. A number of I/O processors are coupled to both I/O busses. I/O devices are accessed through a pair of identical (redundant) I/O processors, but only one is designated to actively control a given device; in case of failure of one I/O processor, however, an I/O device can be accessed by the other one without system shutdown.

Abstract: Method and apparatus for measuring the repeat length (L) of a moving web (20) includes forming a plurality of detectable marks (80) along the length of the web (20) at a repeated length interval.  First (70) and second (72) detectors positioned along the web path are separated by known distance (S).

Patent CA-2046283-A1 (CA)
Inventor: SCHER HERBERT B
IPC: A01N25/28
Filed: 1990-01-31
Abstract: Microcapsule formulations are combined with emulsions or particle dispersions in a single-package formulation which is storage-stable and provides substantially the full efficacy of each of the two forms as if applied individually. The single-package formulation is suspension having two dispersed phases -- the first being an active species encapsulated in a shell of inert polymeric diffusion-limiting material (i.e.) a microcapsule), and the second being an active species in water-insoluble form with no diffusion-limiting barrier at its surface. An appropriate suspension system is included to prevent the dispersed phases from agglomerating within themselves and with each other. The invention is useful in combining two different active ingredients as well as in combining immediate-delivery and delayed-delivery forms of the same active ingredient.      The invention may for example involve combining a biocide with an activity modifier such as a safener, with the effect of lowering the needed amount of one or the other by removing it to a separate phase. In certain cases, a unique combination of surface-active agents maintains the phases in suspension.

Title: Flame detector using a discrete fourier transformer to process amplitude samples from a flame signal
Inventor: KOMPELIEN ARLON D
IPC: G06F17/14
Filed: 1991-09-25
Abstract: ABSTRACT OF THE DISCLOSURE    A circuit for detecting presence of a flame receives a flame signal from a standard photocell positioned to receive radiation from the flame and digitally processes the amplitude variations in the photocell's output to sense for the presence of frequencies near a frequency which is characteristic of a flame.  The frequencies substantially higher than the characteristic frequency are filtered from the signal, and the remaining signal is sampled at a frequency which is preferably four times the characteristic frequency.  The samples are converted to digital values and processed using a discrete Fourier transform.  If the value resulting from the transform operation exceeds a preselected value, presence of a flame is essentially certain.  Such digital processing allows use of a dedicated microcircuit or a microprocessor for the flame sensing function and avoids the need for many large discrete components.

Filed: 1992-03-20
Abstract: ABSTRACT OF THE DISCLOSURE A system and method for processing image data from a document and for producing a compressed binarized version of the image data for transmission to or use by subsequent users.  Processing of the image data is done in parallel after the scanning of the document is started but before the entire document is scanned.  A splitter is used to divide a scan line of image data produced by an imager at the scan line into a plurality of channels, with each channel having at least one overlap area of pixels and with the overlap areas of pixels being used to avoid errors between channels.  Thresholding and compression are performed by each one of the channels in parallel. The compression is performed in a direction which is perpendicular to the direction of scanning and conforms to a standard compression algorithm like CCITT Group 4.

Abstract: Disclosed is a pedicle-screw holder designed to be linked by joint with a screw (2) having a threaded shaft (3) and a sphere-segment head (4) and with a rod (16). In order to lower the cost of stocking screws of different shaft lengths and shaft diameters, the holder has a holder space (7) inside it, at one end of which is a bore (8) through which the threaded shaft (3) passes and, adjacent to the bore, on the inside, a hollow sphere-segment section (9) against which the head of the screw (2) to be held rests, and at the end remote from the bore (8) an opening (10) through which the screw (2) can be inserted. The invention also calls for a pressure element (18) which, when screw and holder are assembled, hexerts a force on the screw head such that the head is pressed against the hollow sphere-segment section. The new holder means that only screws with very different shaft dimensions have to be stocked since screws can be inserted in common holders.
