Patent CA-2060495-A1 (CA)
Inventor: MCNAUGHTON JAMES
IPC: F16L37/098
Filed: 1992-01-31
Abstract: A unique quick connect fluid coupling is disclosed in which tube  inner end does not contact a seal  if  the  tube is not  fully connected.   Preferably, a retainer retains  the  tube within the bore. The retainer is of the avalanche type such that a high force is required to insert the tube, and once this high force is overcome the momentum of the tube carries it to its fully inserted position.  No seal is formed between the tube and seals within the housing unless the tube has moved beyond the point where the high force begins.  Once the tube has moved beyond that point,  it will be fully connected.  The invention ensures that there would be no seal between a tube and a housing unless the tube is fully connected.

Abstract: A seal for a container having an outwardly directed annular rim.  The seal includes a top panel with a central section and an annular lever section integrally joined to the central section by a living hinge.  A side wall integrally depends from the outer periphery of the lever section and includes an inwardly directed concavity for receiving the rim edge.  A continuous convexity below the concavity provides for a snap-mounting of the seal to the container rim and a vertical skirt below the convexity provides for a guide for mounting the seal.  A fulcrum rib depends from the undersurface of the lever section and engages the container rim on a depression of the top panel at the hinge to swing the side wall away from the rim.  Vent openings are provided through both the fulcrum rib and the convexity to maintain pressure release air flow as the seal is mounted and removed.

Abstract: ABSTRACT OF THE DISCLOSURE   A secure storage drawer and an installation clamp for the drawer are disclosed.  The drawer is suitable for mounting to a horizontal surface without surrounding cabinetry. Suspension rails which support the slides for the drawer are so designed that when the drawer is closed there are no exposed fasteners.  Tampering is thus discouraged.  The drawer has a wide shallow partitioned front storage area and a wide deep rear storage area which is large enough to accommodate purses or handbags.  The drawer is readily retrofitted to installed furniture.  An advantage of the drawer is that it provides generous storage capacity yet permits a seated user to move freely across a front of a desk or table to which the drawer is mounted.  The installation clamp permits a drawer to be retrofitted to installed furniture quickly and efficiently in situ.  The installation clamp is useful for mounting any drawer supported by suspension brackets in accordance with the invention.

Abstract: An ultrasonic processing method and apparatus are disclosed wherein during the processing time interval the motional amplitude of the resonating horn and thereby the power to the workpiece is changed responsive to the production of a control signal.  The control signal is process related and generated, in a typical example, when there is sharp rise in the power curve.          In another example, the power is changed responsive to a changing dimension of the workpiece.  In typical examples, the control signal reduces the motional amplitude for the remaining time interval.

Abstract: A system and a method for marking a continuous substrate (14), such as a sheathed wire, are disclosed. An aqueous-based ink is deposited onto a continuous substrate passing through an ink deposition means (32). A gas, heated by a heater (54, 56) and directed by a blower (53, 60) across the continuous substrate (14), heats the deposited aqueous-based ink in an amount sufficient to cause a pigment of the aqueous-based ink to bond to the substrate, thereby marking the continuous substrate (14). In an alternate embodiment, a system for marking a continuous substrate includes an elongate housing which is disposed substantially vertically. A  continuous substrate, onto which an aqueous-based ink has been deposited, is directed upwardly through the housing. Gas, which has been heated in a tube disposed within the housing, is directed across the continuous substrate, causing the pigment of the aqueous-based ink to bond to the continuous substrate and thereby mark the continuous substrate.

Title: Image undithering apparatus and method
Inventor: KNOWLTON KENNETH C
IPC: H04N1/40
Filed: 1991-10-01
Abstract: A method enables a dithered representation of an image to be converted to a continuous tone representation of the image. This undithering method compares the regions of dithered representation with sections of dither patterns to determine an appropriate continuous tone representation from which the dithered image could have resulted. When the continuous tone representation is found the region is converted into a continuous tone representation. This procedure maybe spatially iterated on a pixel by pixel basis until all of the initial representation of the image is converted into a continuous tone representation. The procedure may also be modified to account for line art. Furthermore, the procedure may be applied to produce adjustments in the size of the picture including miniaturizations and enlargements of the original image. In accordance with this application, dithered portions of the original image are redithered in a manner to produce an alternative size output image. Similarly line art portions of the original image are treated as grey scale values and redithered to produce the alternative size representations of the line art.

Title: Electromagnetic induction heater
Inventor: IGUCHI ATSUSHI
IPC: H05B6/36
Filed: 1993-08-13
Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed is an electromagnetic induction heater in which magnetic flux diffusing members are fixed to at least two ends of an iron core wrapped with an electric wire to form a coil, and a metal plate is connected to the magnetic flux diffusing members to heat a wide area of the metal plate uniformly.  By supplying a commercial low frequency alternating power source of 50-60Hz to the coil,  a magnetic flux is generated in the iron core.  The magnetic flux, flowing in the magnetic flux diffusing members, is diffused  in  a  longitudinal  direction.   Diffused magnetic  flux flows through the metallic plate to generate Joule heat over the plate.   Therefore,  the  entire  surface  of  the  metal  plate  is heated   uniformly.    Either  a   single-phase   or   three-phase alternating power source is used in this invention.
