Patent CA-1284427-C (CA)
Title: Integrated head-up and panel display unit
Inventor: FERRER JOHN J
IPC: G02B27/00
Filed: 1987-03-06
Granted: 1991-05-28
Abstract: INTEGRATED HEAD-UP AND COLOR PANEL DISPLAY UNIT                 ABSTRACT OF THE DISCLOSURE An integrated head-up and panel display system for aircraft cockpits and the like is disclosed.  The system utilizes a wavelength-sensitive fold mirror to separate the HUD image and the panel images.  The system includes a monochromatic HUD image source for projecting the HUD image toward the fold mirror, and at least one panel display image source for projecting panel imagery toward the fold mirror.  The transmission function of the fold mirror is notched at the wavelength of the monochromatic HUD image source.  Thus, the fold mirror reflects the HUD image in the direction of the HUD optical combiner which reflects the HUD image to the system exit pupil.  The fold mirror is adapted to transmit light in the visible spectra outside the narrow bandwidth of the HUD image source, so that the panel image is transmitted through the fold mirror to a look-down display screen assembly.  The screen assembly may be a diffusion screen for providing an image plane at the screen, or an assembly of optical elements for providing a panel image superimposed at the system exit pupil.

Granted: 1991-06-11
Abstract: ABSTRACT OF THE DISCLOSURE          A gas burner assembly for a fireplace is shown.          The assembly is operative to produce a flickering yellow flame pattern which closely resembles to that produced by a natural wood log fire, yet there is virtually no formation of carbon monoxide gas.

The gas pipe is located adjacent to the bottom of the casing and having a plurality of openings facing downwards. The artificial log comprises a flexible metal tube wrapped with a ceramic fibre blanket which is impregnated with a colloidal compound and thermally cured.          The surface of the log is textured and painted to simulate the appearance of a natural wood log.

Title: Method and apparatus for removing pseudo-sync and/or agc pulses from a video signal
Inventor: RYAN JOHN O
IPC: H04N5/76
Filed: 1987-09-14
Granted: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE          Added pseudo-sync pulses and AGC pulses are removed from a video signal to enable acceptable video recording thereof.  The added signals previously interfered with acceptable video recording of the video signal because the automatic gain control of videotape recorders sensed false recording levels, while conventional televisions receivers were unaffected by those modifications to the video signal.  Removal of the added pulses permits acceptable video recording of the previously modified video signal.  A selectively-operable clipping circuit is used to remove selected negative-value components (i.e., pseudo-sync pulses) from the video signal, while added AGC pulses are effectively blanked from the video signal with an electrically-operable switch.  Both the blanking and clipping functions are selectively achieved by sensing both the normal sync pulses of the video signal and the added pseudo-sync pulses.  Method and apparatus are disclosed for "cleaning up" video signals modified by either the pseudo-sync pulses alone, the AGC pulses alone, or combinations thereof.

Title: Preconditioning apparatus for extruder
Inventor: HAUCK BOBBIE W
IPC: B01F7/04
Filed: 1987-10-13
Granted: 1991-12-24
Abstract: PRECONDITIONING APPARATUS FOR EXTRUDER            Abstract of the Disclosure A conditioning device for an extruder includes two juxtaposed, frustocylindrical, inter-communicated chambers, one chamber of which has greater cross sectional area than the other cham-ber.  A mixing shaft centrally located within the small chamber carries a number of radially extend-ing beaters which rotate at a speed twice that of the rotational speed of paddles mounted on a second mixing shaft located in the large chamber and material introduced into the vessel is passed from side-to-side between the two chambers while being advanced along the length of the vessel. The use of relatively fast moving beaters within a small mixing chamber in combination with relative-ly slow moving paddles in a larger mixing chamber enables flour-like materials to be properly blend-ed with water with both sufficient agitation and proper retention times within the vessel.   In an alternate embodiment of the invention, the vessel is tiltable about an axis parallel to the longitu-dinal axis thereof, in order to bias the materials under the influence of gravity toward one chamber or the other and to thereby vary the residence time of the materials within the vessel and the mixing characteristics of the device.

Granted: 1992-04-14
Abstract: Abstract of the Disclosure A releasable and gas tight sealing apparatus for construction panels of a paint baking oven which relieves the buildup of gas pressure within the oven in the event of an explosion.  The apparatus has tongue and groove members and a compressible cord rope received in the groove members.   In assembly and during normal use of the oven, the tongue is received in the groove and bears on and compresses the cord rope to provide a gas tight seal.  In the event of an explosion, the construction panels are forced outwardly which disengages the tongue and groove members and relieves the buildup of gas pressure in the oven.

Title: Thick film packages with common wafer aperture placement
Inventor: WILBY JOHN L
IPC: H01L23/28
Filed: 1988-07-25
Granted: 1991-04-02
Abstract: ABSTRACT           A multilayer thick film package for housing a microchip is formed from a series of insulating wafers.  A wafer adapted to occupy an outer position on the package has a first series of apertures positioned to correspond with the placement of pins on the package, and wafers adapted to occupy inner positions on the package each have a second series of apertures.  The second series of apertures is comprised of apertures that correspond in position to the first series of apertures, but is also comprised of additional apertures.  Conductive material in the additional apertures allows electrical connection to be made within the package to the conductive lines that extend from the pins of the package to the inner package interface adapted to abut to a microchip.  Two forms of the electrical connections are discussed. One form relates to connection of some of the conductive lines on a wafer to an electrically conductive coating at ground potential on one of the other wafers, this form being used in frequency sensitive applications.  Another form relates to connection of some of the conductive lines on a wafer to a parallel line or lines on another wafer for reducing the resistance in the line in power sensitive applications.  Packages capable of housing a variety of microchips may be formed from wafers each having only a first or a second series of apertures, thus reducing hard tooling cost.
