Abstract: An image display system  (10)  includes an image buffer (20,22) having a plurality of addressable locations for storing image pixel data.  The  system further includes circuitry (24,34,36) coupled to an output of the image buffer for converting image pixel data read therefrom to electrical signals for driving an image display (18). The circuitry is responsive to signals generated by an image display controller (16) for generating one of a plurality of different timing formats for the electrical signals for driving an image display having a specified display resolution.  The  apparatus  further  includes  circuitry (40,42)  for configuring the image buffer in accordance with the specified display resolution. The image buffer is configurable,  by example,  as two,  2048 location by 1024 location by 24-bit buffers and one 2048 location by 1024 location by 16-bit buffer; or as two, 2048 location by 2048 location by 24-bit buffers and one 2048 location by 2048 location by 16-bit buffer.  Each of the 24-bit buffers store R,G,B pixel data and the 16-bit buffers each store a color index (CI) value and an associated window identifier (WID) value. Circuitry at the output of the image buffer decodes CI  and WID values into R,G,B pixel data and a Key value specifying pixel mixing.

Patent CA-2069979-A1 (CA)
Inventor: MOREIRA ALBERTO
IPC: G01S13/90
Filed: 1992-05-29
Abstract: In a method of generating a reference function for pulse compression of frequency, phase and/or amplitude-modulated signals, a reference signal (ho(t)) corresponding to a conjugated complex function of an error-free frequency-modulated signal (so(t)) and a signal (sf(t)) containing phase and amplitude errors are generated in two following FFT units by a Fourier transformation in the form of signals (Ho, Sf) present at the outputs thereof. Thereupon, the signal (¦Ho¦2) is generated from the output signal (Ho) of the one FFT unit by means of an intensity-forming unit and the signal (1/Sf) is generated from the output signal (Sf) of the other FFT unit by means of a reciprocal-forming unit and said two signals (¦Ho¦2, 1/Ff) are multiplied together in a following multiplying member; finally, the output signal (Hi) of the multiplying member is subjected in an IFFT unit to an inverse transformation for generating the reference function (hi(t)) in the time domain.            For performing a pulse compression in the time domain a pulse response (fo(t)) corresponding to the function (sin(x)/x) is then formed from the signal (sf(t)) and the generated reference function (hi(t)) in a convolution unit (3).

Magnifying this display would produce an inexpensive screen capable of being mounted on face goggles, or alternate stand alone apparatus. Using an optic system, the eye could perceive an Image of various size screens. The chip being so close to the eye would require very little illumination. Advantages of this apparatus are numerous especially due to low power consumption and light weight. Ideally this would be suitable for portable lap top Computer and Video systems. Dual chips could also be used to produce true Three Dimensional images capable of large screen viewing.            (4) CLAIMS,   (2) DRAWINGS

Title: Self-cleaning strainer
Inventor: LESCOVICH JOSEPH E
IPC: B01D33/58
Filed: 1992-08-11
Abstract: A  self-cleaning  strainer  comprises  a  vertically disposed housing which contains a rotatable strainer basket.  The housing has an open top, closed by a closure plate, an inlet adjacent the top of the housing and an outlet adjacent a closed bottom of the housing, the closed bottom having a flush discharge opening.  The components used to rotate the strainer basket are disposed outside the flow of any water containing particulates that enters the housing.   Cleaning devices such as a scraper blade  supported  in the  strainer basket,  a rotatable brush supported in the strainer basket,  and a water jet manifold disposed between the housing sidewall and the sidewall of the strainer basket are used to clean the rotatable strainer basket.          In one embodiment, a hollow backwash conduit with a passage through the sidewall is positioned adjacent the inner surface of the strainer basket and communicates with a sealable aperture in the wall of the housing.  Upon opening of the aperture, cleaned water flows through the side wall of the strainer basket, removing particulates therefrom, and out the hollow backwash conduit.  An intermittently rotatable brush is also provided to brush the inner surface of the strainer basket.

Patent CA-2079419-A1 (CA)
Inventor: PULLEN ELAINE A
IPC: B41J2/195
Filed: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus are disclosed for controlling the flight time and composition of a marking fluid used in a continuous jet marking system.  A three-way valve permits switching between fresh ink and system ink supplies.          Periodically a comparison of pressure required to maintain a constant drop flight time is made by a controller.  Because both supplies are in the same operating environment any difference in pressure is due to a change in system ink viscosity.  Make up solvent is added, if necessary, via a pump to restore viscosity to desired values.

Title: Rotary lobe pump
Inventor: DODD IAN
IPC: F04C2/02
Filed: 1992-10-02
Abstract: ABSTRACT OF THE DISCLOSURE    The pump is improved to facilitate maintenance of the pump, especially when the pump is installed in difficult to access  locations.  A  split  housing  for  the  shaft/pump compartment seals is provided to give easy access to the seals while allowing the shaft bearings to be located near to the pump rotors. A front cover plate is sealed to a front end of the pump compartment and is connected to the pump housing by a hinge bolted to the front cover plate outside the seal of the front cover plate in such a way that the front cover plate can be reversed to avoid the need to replace the front cover plate when only one side is worn down. A pair of timing gears interconnect the two shafts of the rotors and are provided in a rear compartment which is closed by a rear cover plate. A timing cover plate closes an opening surrounding one of the shafts passing through the rear cover plate, and when the pump is jammed, the timing cover plate can be removed to gain access to a taper locking assembly of the timing gears to realign the two shafts with respect to one another.

Title: Method and apparatus for desalination of saltwater
Inventor: LUMBRERAS Y GIMENEZ MANUEL
IPC: B01D1/16
Filed: 1991-04-26
Abstract: Method and apparatus for seawater potabilization, wherein saline water is resolved by atomizing process, through mixing with compressed air in droplets of maximum 3 microns of diameter, which are projected at a velocity close to that of the sound, injecting them in an environmental air drag area where the droplets loose the water by evaporation within a small distance from the ejection point thereby causing the salt particles to precipitate completely out of the solution. The generated water vapor condenses thereby forming a suspension of fresh water droplets inside a chamber till the fresh water suspension is evacuated from the environmental space to containers prepared to receive the droplets and where the suspension precipitates in order to collect the resulting fresh water flow. All the process is carried out at environmental temperature.

Title: Process for moving an item with drillings during its wet chemical treatment e.g. galvanisation, and device for implementing the process
Inventor: VAN KEMPEN JOS
IPC: H05K3/18
Filed: 1991-07-04
Abstract: ABSTRACT OF THE DISCLOSURE      The invention is primarily based on a process for the to and fro movement of an item with drillings during its wet chemical treatment.  In order, especially with an unfavourable ratio between the thickness of the item and the drilling diameter, to be able to be sure of removing existing residues and/or gas bubbles in the drilling, it is proposed that the item be vibrated at a frequency of at least 4-5 Hz, the direction of vibration be at least partially and/or in time directed along the longitudinal axis of the drillings and the vibration be exerted only or at least primarily on the bearing part of the item.  In addition, the invention relates to a device for implementing the process, whereby several treatment stations are arranged one behind the other with the purpose of largely avoiding the drawback of prior art embodiments of the transfer of such vibrations to the stationary part of such an installation.  To this end, at least one vibration generator generating vibrations at a frequency of 4-5 Hz is fitted to a transport and/or supporting component by means of which the item is held during transport, insertion in the bath and its immersion therein, and between the vibration generator and the stationary parts of the installation there are blocking and at least largely damping means.
