Title: Process for preparing rubber-modified asphalt compositions
Inventor: HESP SIMON ADRIANUS MARIA
IPC: C08L95/00
Filed: 1995-08-01
Abstract: A modified asphalt composition having improved low-temperature fracture properties is obtained by devulcanizing crumb rubber, preferably ground rubber tire.  The devulcanization is effected without the use of harsh oxidizing treatments or the addition of potentially hazardous solvents, by fractional distillation of a mixture of the rubber and crude oil to a temperature at which substantially complete devulcanization occurs, around 300°C.  Alternatively, the vulcanized crumb rubber can be directly blended with asphalt and the mixture heated to a devulcanization temperature with gentle stirring.  Compositions are relatively inexpensive and simple to produce and, not having been oxidized, may be expected to show better long-term aging and fatigue performance compared to air-blown asphalts and the like.

Title: Multiport analyzing, time stamp synchronizing and parallel communicating
Inventor: ZHANG JING
IPC: H04J3/06
Filed: 1995-09-27
Abstract: A plurality of digital transmission network analyzers are arranged to analyze and compare the appearance of a data packet on the plurality of ports of a network.  Each analyzer has its own internal clock for time stamping of data packets in addition to other internal timing purposes.  In order to synchronize the time stamping of the packet as it appears to each analyzer at a each different port, the clock outputs of the several analyzers are connected together; and a controlling CPU commands one of the analyzers to supply the master clock to the others.  That master analyzer then commands the other analyzers to disable or disconnect their own clocks, thereby all of the analyzers involved in a given test are under timing control of the clock of the master analyzer.  Packet headers and time stamps are transmitted between analyzers for comparison, analysis, and reporting to the controlling CPU.  This analyzer intercommunication is done over a separate bus that interconnects all of the analyzers and the controlling CPU.

Title: Resilient safety barrier
Inventor: VOIGT WILLIAM L
IPC: E01F15/00
Filed: 1995-10-23
Abstract: A resilient mounting system for safety barriers, including guardrails, hand rails, etc., includes a urethane rubber or other resilient material substantially between the periphery of the barrier and a floor or base. The barrier is biased against the base so as to provide an stiff yet resilient impact resistance that yields to absorb the energy of impact, such as from a vehicle, rather than requiring the structural material of the barrier itself to absorb and perhaps become dislodged or deformed by the impact. The resilient material can be shaped generally like the periphery of the barrier or it can be a standard shape that is replicated and arranged to engage a support for the barrier. A rail is resiliently mounted between two supports, the resilient mounting being arranged to permit limited relative movement between the rail and the supports but resisting removal of the rail from the supports.

Patent CA-2163914-A1 (CA)
Title: Method and apparatus for detecting malignancies in living tissue
Inventor: PARENT ANDRE
IPC: A61B5/00
Filed: 1995-11-28
Abstract: The most common method of determining whether a breast contains cancerous tissue utilizes ionizing radiation, i.e. x-rays, which possible have tissue damaging properties.          Ultrasound and transillumination using visible and non-visible light have been proposed as safe alternatives to x-radiation.          It has been found that lasers can be used as a light source in a breast tissue transillumination process.  However, due to the high scattering coefficient (or diffusing properties) of breast tissue, it is not possible to obtain images having good resolution using classical transillumination techniques, even when a laser is used as the light source.  When passing through a diffusing medium, a laser pulse decomposes into three classes of photons, namely ballistic, snake-like and diffuse photons.  In most practical situations, the ballistic photon portion of a laser pulse, which travels in a straight line, does not pass through the tissue, i.e. only snake-like and diffuse photons pass through the tissue.  It has been suggested to use the natural temporal separation of light passing through highly dispersing medium to separate the snake from the diffuse photons using time-gating techniques.  The diffuse photons are then disregarded.  Rather than discarding the diffuse photons, it is proposed by this invention to use both the snake-like and diffuse photons in a method involving time gating and multiple field of view techniques to obtain a more precise evaluation of the scattering coefficients, i.e. a map of the interior of a region of the sample, whereby the presence (or absence) of tumors is determined.  The use of multiple field of view and time gating techniques will yield a relatively clear picture of the structure of the tissue.

IPC: B01D53/047
Filed: 1996-09-27
Abstract: A method and apparatus for the removal from a feed gas stream such as air of at least two contaminating gas components such as water and CO2 features repeated cycles of operation which comprise: feeding the feed gas stream in a feed direction at a first pressure and at a first temperature, e.g. 30°C in contact with a solid adsorbent such as alumina that adsorbs a first of said contaminating gas components more strongly and a second of said contaminating gas components less strongly so that said first contaminating gas component is adsorbed in an upstream portion of said adsorbent and said second contaminating gas component is adsorbed principally in a more downstream portion of said adsorbent, halting the feeding of said feed gas stream, depressurising the gas in contact with the adsorbent to a second, lower pressure, feeding a regenerating gas such as dry nitrogen at said second pressure and at a second higher temperature, e.g. 70°C, in a direction counter-current to said feed direction in contact with said adsorbent to produce a heat pulse travelling in said counter-current direction to desorb said less strongly adsorbed second contaminating gas component from the downstream (with respect to the feed direction) portion of the adsorbent by TSA whilst at the same time desorbing the more strongly adsorbed second contaminating gas component from theupstream (with respect to the feed direction) portion of the adsorbent by PSA, ceasing said flow of regenerating gas before the heat pulse travels as far as the upstream portion of the adsorbent in which is adsorbed the first contaminating gas component, and repressurising said adsorbent. Improved capacity for the more weakly adsorbed component allows longer cycle times than in PSA and hence longer repressurisation times with consequently less variation in purified gas output.
