Title: Cross-connect method for stm-1 signals of the synchronous digital multiplex hierarchy
Inventor: POSPISCHIL REGINHARD
IPC: H04L5/22
Filed: 1990-08-29
Abstract: Cross-connect method far STM-1 signals of a synchronous digital multiplex hierarchy. Data blocks having differing multiplex structure of the synchronous digital multiplex hierarchy are processed in common in a cross-connect equipment. Controlled via a bus by a microprocessor, AU-4 administration units of STM-1 signals are resolved into virtual container groups of approximately the same length such as TUG-31 and TU-31. After the removal of auxiliary signals that are no longer required, an individual switching matrix network clock matching painter and an individual switching matrix network overhead are respectively attached to these virtual container groups for the formation of uniform switching matrix network input signals (D39, D52). After a rearrangement in a switching matrix network, switching matrix network clock matching pointers and overheads are again taken from the switching matrix network output signals and are evaluated. Subsequently, the input signals (D39, D52) are subjected to a corresponding multiplexing method for the formation of new STM-1 signals. This method is employable in cross-connect and drop insert multiplexing equipment.

Title: Process for the manufacture of a carbon fiber reinforced composite material having a ceramic matrix
Inventor: ROCHER JEAN-PHILIPPE
IPC: C04B41/50
Filed: 1991-02-05
Abstract: In the process according to the invention, before the ceramic matrix is densified, the carbon fiber reinforcement material is subjected to a thermal treatment in a non-oxidizing environment at a temperature greater than 1300° and less than 2200°C, to act on the bonding between the fibers and the matrix.      If a preform of the carbon fiber reinforcement material is formed prior to densification by a matrix, then the thermal treatment may be performed on the preform, prior to densification by the matrix.      If the matrix is densified by chemical vapor infiltration inside a furnace, then the thermal treatment may be performed inside the infiltration furnace prior to the densification.      The thermal treatment grants a significant improvement in the strength of the resulting composite material.

Patent CA-2038344-A1 (CA)
Inventor: COUGHLAN THOMAS N
IPC: C09D5/00
Filed: 1991-03-15
Abstract: Conventionally, paints which are formulated for use as markings on roads have also been used as markings on airport runways but have been found unsatisfactory since airport runway markings have special requirements. The present invention provides a high opacity thin coat concept airport runway marking paint comprising 20-60% by weight of titanium dioxide in the paint or higher within the critical pigment volume concentration (C.P.V.C.), extenders such as Barium Sulphate, Laminar Talc, Calcite or Dolomite used alone or as blends thereof, binders such as Plasticised Chlorinated Rubber, Acrylated rubber, Epoxy, Polyurethane or emulsified resins and an anti-skid aggregate comprising crushed glass particles or calcined Aluminum oxide or the like. Airport runway markings need frequent maintenance re-application of paint in order to obliterate the black marks left after contact with aircraft tyres. The high opacity paint has the advantage that it can be sprayed on at very thin film thickness thereby minimising the tendency of the build up of thick smooth film to potentially hazardous levels.

Title: Safety needle container
Inventor: HOLLISTER WILLIAM H
IPC: A61M5/31
Filed: 1991-07-18
Abstract: ABSTRACT OF THE DISCLOSURE A universal safety adapter usable with different types of needles and syringes has integral first and second portions and a  housing,  including  an  integral  compressible  section connecting a main body section to an end cap section, flexibly connected to one of the portions.  Alternatively, in place of the compressible section,  a compressible joint coupling a unitary housing to the base of the adapter may also be used.      In the case of the first portion being mated to the hub of a needle assembly, the housing is flexibly connected thereto by a living hinge.  The needle assembly is threadedly mated with an internally threaded annular collar surrounding a protrusion which is to be coupled to the hub of the needle assembly.  The second portion of the safety adapter, in a first embodiment, includes a female luer that can be mated with different types of syringes, such as a luer slip or a luer lock.  Once the needle assembly has been threadedly mated to the first portion of the safety adapter, to ensure that the cannula of the needle assembly is not exposed so as to preclude accidental pricking by the needle, the housing is pivoted to a position whereby it completely  envelops  the  cannula.    To  provide  additional protection, the end cap section, which has adapted thereto an elastomer, is urged longitudinally toward the main body section so that the tip of the needle is completely encased by the elastomer as the compressible section  (or joint)  collapses under pressure.  The dead space volume at the junction where the needle is connected to the syringe can be substantially reduced by a second embodiment of the safety adapter of the present invention which includes a male extension within the female luer.

Title: Automatic monitoring of digital communication channel conditions using eye patterns
Inventor: NOHARA TIMOTHY J
IPC: H04L1/20
Filed: 1991-11-29
Abstract: A digital signal transmission channel degradation monitor for determining the error rate in a received data signal includes circuitry to generate an eye pattern signal for the received data signal which eye pattern signal is applied to a grid containing a number of cells defining regions in an ideal eye pattern. Each cell contains circuity to count the number of time an eye trace is located in that particular cell over a predetermined period of time. A number of cells within the ideal eye pattern area are grouped to define a predetermined pseudo error region. The number of times an eye trace enters into that error region over a predetermined time provides an indication of the generalized pseudo error rate for the transmission system. In addition, the number of times an eye trace is located in particular cells through the grid over a predetermined period of time can determine the type of stress that the transmission system is undergoing. This detector can be automated to determine both the error rate and type of stress for the data transmission system.

Title: Fluid dispensing instruments having barbed nib holders
Inventor: LINDSEY RAYMOND A
IPC: B43K8/02
Filed: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE         Fluid dispensing instrument, such as a writing instrument, comprising a nib holder and a nib.  The nib holder comprises a generally cylindrical inner wall disposed between its front and back ends, having an opening at one end to receive a nib.  Stops limit the depth of axial insertion of a nib through the opening. Barbs prevent axial withdrawal of a nib from the opening. The nib comprises a fluid dispensing tip defining its front end and a body made at least in part of resilient material defining its back end.  When the writing instrument is assembled, the body is engaged by and resiliently deformed between the barb means and stop means.  Also, a method of permanently securing a nib in the nib holder of a fluid dispensing instrument, comprising the steps of inserting the nib in the nib holder through the opening until an abutment of the nib engages a stop of the nib holder, applying an insertion force sufficient to compress the resilient part of the nib and thus move at least part of the nib axially in the nib holder, and removing the insertion force.  When the insertion force is removed, the compressed part of the nib relaxes and the part of the nib which previously moved axially in one direction moves axially the other way. When this happens the barb of the nib holder engages and digs into the moving part of the body.  Some residual tension will remain in the body after the insertion force is removed if the barbs engage sufficiently to prevent further axial movement of the nib body before the compressed resilient portion of the nib is fully relaxed.
