Filed: 1996-06-21
Abstract: A fluid-tight container adapted to contain a fluid, volatile solid, or absorbent for a fluid, in which at least a portion of the container includes a material which, when sufficiently stretched, develops sufficient porosity to allow passage of the fluid through the material.  In some embodi-ments, the material may be a film.  For example, the film may be a filled film.  As another example, the film may be an elastic film, such as a hard-elastic film.  In other embodi-ments, the material may be a laminate.   Components of the laminate may be a film or a nonwoven web, in which case the film may be a filled film or an elastic film, such as a hard-elastic film. Desirably, the laminate will include a film and a nonwoven web.   The fluid-tight container may include a fluid-absorbing solid, such as silica gel or activated carbon for absorbing moisture or odors.  In such case, the movement of  fluid  through  the  material  is  into  the container. Alternatively, the fluid-tight container may include a liquid. For example, the container may include a gel,  cream,  or lotion,  in which case the movement of fluid through the material is from the container.  Also provided is a method of dispensing a liquid which involves providing a fluid-tight container as described above, providing a liquid in the fluid-tight container, and stretching the container.

Abstract: A system and method for testing communication devices, such as speakerphones, are disclosed. In one embodiment, a two-way conversation is pre-recorded for playback through one or more test communications devices to evaluate communications device performance. The test set-up permits the recording of a two-way full-duplex communication onto two or more channels of the same recording/ playback device, thereby preserving the content and timing relationships between speech segments. A comparison can be made between the live conversation and the conversation as it was realized in the playback condition over a test communications device. The original and the test will be different based on the performance of the communications device. This method decreases the test time and provides other efficiencies useful in connection with testing, evaluation and quality control for communications device acoustic and network performance testing.

Title: Positive locking trailer tail
Inventor: PEAKMAN KEN
IPC: B60P1/43
Filed: 1997-01-16
Abstract: There is provided a flat bed trailer including a hinged ramp tail which can be raised between a lower loading and an upper transport position. The ramp tail is raised and lowered by a linkage and extensible lifting means acting on the linkage. The advantange of the linkage of the present invention is that the extensbile liftming means - hydraulic cylinders - are retracted when the ramp is in its raised position, rather than being extended. In addition the linkage provides for an over-center lock further strengthening the ramp tail in its raised position, thus significantly lessening the amount of strain placed on the hydraulic cylinders and other mechanics as compared to that in the prior art.

Patent CA-2202891-A1 (CA)
Inventor: WIEBE LEONARD I
IPC: A61K51/00
Filed: 1995-10-20
Abstract: Diagnostic, radiotherapy, and chemotherapy methods which may be used in conjunction with gene therapy techniques, and the use of certain compounds in performing these methods. The methods are applicable to populations of cells into which a foreign gene has been transferred, which foreign gene expresses a protein which preferably is not naturally occuring within the cells. A  compound is selected which will interact selectively with the protein expressed by the foreign gene to produce a product which is trapped within the cells, is cytotoxix or cytostatic to the cells, or both, depending upon whether the compound is being used for diagnostic purposes or for radiotherapy or chemotherapy purposes. In the case of diagnostic applications, trapping of the product, which is labelled, permits the product to accumulate in those of the cells in which the protein has been expressed by the foreign gene, thus facilitating detection of the labelled product in those cells. In the case of radiotherapy applications, trapping of the product, which is radioactive as a result of the compound being radiolabelled, permits the product to accumulate in those of the cells in which the protein has been expressed by the foreign gene, thus facilitating radiotherapeutic effects directed specifically at those cells. In the case of chemotherapy applications, interaction of the protein with the compound has either a cytotoxic or a cytostatic effect on the cells, which is enhanced if the product is trapped within those of the cells in which the protein has been expressed.

Title: Wheel slip control parameter variation process
Inventor: WOOD JAMES A
IPC: B60T8/1761
Filed: 1997-10-16
Abstract: A wheel  slip  control  system employs  a method of varying the detection and correction parameters it uses based on whether the wheel/axle combinations on a truck of a rail vehicle operate in the coupled or decoupled modes of operation.   The control  system executes programming  code  featuring detection  and correction logic.  The steps of the method include deriving both detection parameters optimized for each mode called coupled and decoupled detection parameters and correction parameters optimized for each mode called coupled and decoupled correction parameters.  Another step involves monitoring the amount of dynamic braking applied to the  wheel/axle  combinations.     Yet  another  step  involves determining whether the amount of dynamic braking lies for a preset time period within a preset zone of operation for the dynamic braking of the wheel/axle combinations on the truck.  The method provides the coupled detection parameters to the detection logic if the amount of dynamic braking lies within the preset zone for the preset time.   Alternately,  it provides the decoupled detection parameters to the detection logic if the amount of dynamic braking fails to lie within the preset zone for the preset time.  The method provides the coupled correction parameters to the correction logic if the amount of dynamic braking lies within the preset zone for the preset time.  Alternately, it provides the decoupled correction parameters to the correction logic only if the amount of dynamic braking fails to lie within the preset zone
Patent CA-2227009-A1 (CA)
Inventor: MILLER BRADLEY J
IPC: B24D3/00
Filed: 1998-01-15
Abstract: An abrasive grit for a metal bonded Single Layer abrasive tool includes abrasivegrains coated with a first active component. The active component is mechanically-bound to the surface of the superabrasive grains. Preferably the abrasive is a superabrasive, especially diamond, and the first active component is titanium, either in the form of elemental Ti or TiH2. The novel grit is made by mixing the first active powder component in a liquid binder to form an adhesive paste; mixing the paste with the abrasive grains to wet the grains, and drying the mixture to adhere active component to the grains. The coated abrasive can be brazed onto a core to form aSingle Layer tool, especially with a brazing composition that includes a bronze alloy and small concentrations of a second active component. During brazing the novel abrasive grains provide excellent surface contact with the brazing composition and the braze strongly bind the grains to the tool core. The brazed composition is easy to chemically or electrochemically strip from the cores of worn abrasive tools to permit reconstruction of the tools.
