Patent CA-2001226-A1 (CA)
Inventor: KAMMEL REFAAT A
IPC: F01N13/02
Filed: 1989-10-23
Abstract: DIESEL ENGINE EXHAUST OXIDIZED                     ABSTRACT OF THE DISCLOSURE     A device for connection to a diesel engine to collect soot and other particulate emissions before the exhaust is discharged to atmosphere.  When the filter becomes loaded with particulates to the point where it either may not function properly or otherwise interferes with the vehicle's operation, a forced regeneration cycle is induced.  During forced regeneration a valve mechanism at the inlet to the device is operated to divert flow from the main flow path into a by-pass passage, and an electric power heater is energized elevating the temperature of the filter to burn off the accumulated particulate material.  The valve mechanism is duty cycled as the forced regeneration process continues.  As the process concludes, the valve open time increases and this increase is monitored to terminate the duty cycle operation so that the main passage through the device is now open.  The main passage through the device contains a series of nested vanes which take the axial flow of particulate-containing exhaust and direct it outwardly through the filter which is located just after the vanes.  In certain embodiments an electrostatic precipitator precedes the filter to enhance soot collection efficiency.

Inventor: SHERIDAN JOHN P
IPC: C05F15/00
Filed: 1990-02-26
Abstract: The present invention provides methods for re-processing incinerator ash to recover phosphates and minerals therefrom. The incinerator ash may be agitated in a bath of sulphuric acid - which may be diluted or concentrated. The process may be carried out at elevated temperatures and/or pressures. Because the incinerator ash contains high concentrations of phosphates of calcium, magnesium, aluminum, or any of them, the agitated mixture will have phosphate-containing compounds, which may then be separated from it. Thereafter, optionally the residue following the separation of the phosphate-containing compounds may be purged of any trace metallic elements that are present in it; and further optionally the residue may then be died and re-ground followed by a cyanide process separation of precious metal elements that are in it. Still further, the residue following the precious metal separation process may be dried to form an aggregate, which once again may have phosphate-containing substances that may be separated from use as fertilizers. In any event, the aggregate may be then mixed with cement so as to form cement-based rigid and solid products such as cement blocks or the like.      Cement-based products having this aggregate tend to be less dense than ordinary cement-based products, they set up quickly, they have a better co-efficient to heat transfer, and they may present a semi-polished appearance at their exposed surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for providing improved phase error measurement as shown and described.   The measured phase error (?E) is used as an input to a SYNCHROPHASER? which provides for phase control of a slave propeller with respect to a master.  The phase error (?E) is the sum of the sensed phase error and 360° divided by Np  times ?COUNT minus ?REF.   ?COUNT is a counted number of phase discontinuities which occur in ?S,  the sensed phase.  The values of ?COUNT and ?E, measured phase output, may be limited in number and magnitude.

Abstract: ABSTRACT          A block made of a resilient material is molded to conform to the inner perimeter of a gun trigger guard.  The trigger is held in a depressed state when the block is inserted.  The block  has  flexible  flanges  formed  on  both  sides  which partially extend around the trigger guard and the depressed trigger to hold the block in place.      At the approximate center, where the undepressed trigger would normally be, a simulated trigger is formed so as to appear to be part of the weapon.  In front of the simulated trigger is an opening into which the trigger finger may be inserted in a normal manner r promoting the appearance of the block as being part of the weapon, disguising the fact that the weapon has been disabled.

The cup dispenser is pivotally mounted about a substantially horizontal pivot, about which the cup dispenser is cyclically pivoted to allow the cup stack to cyclically swing through a dispensing travel arc during a dispensing cycle. A pair of opposed cup separating members are mounted on opposite sides of the stack of cups in the cup dispenser along the dispensing travel arc. The opposed cup separating members are spaced a distance apart substantially equal to the width of a cup just beneath the cup rim, and each of the pair of opposed cup separating members comprises at least one cup separating wedge positioned opposite to a corresponding cup separating wedge in the oppositely positioned cup separating member. The appositely positioned cup separating wedges cooperate to separate the bottommost cup from the cup stack as the cup dispenser is pivoted along the dispensing travel arc. A preferred embodiment of the cup dispensing arrangement includes a cup carousel, having a plurality of the cup dispensers positioned circumferentially therearaund, with each cup dispenser being pivotally mounted relative to the cup carousel by a pivot thereon. Each cup dispenser with an associated pair of opposed cup separating members is supported on the cup carousel for rotation therewith, such that any one of the cup dispensers can be positioned at the cup drop station. A cup dispensing mechanism is positioned at the cup drop station to activate any one of the cup dispensers positioned thereat.

Title: Scanner system for successive irradiation of a working surface, particularly for ultra-violet exposure of a photo emulsion on a seri-graphic printing frame materials, e.g. in mixing plants, for central analysis of the sample
Inventor: ANDERSEN ALLAN V
IPC: B41C1/14
Filed: 1990-11-14
Abstract: A scanner system for successive irradiation of a working surface, particularly for ultra-violet exposure of a photo emulsion on a serigraphic printing frame.                  A B S T R A C T:      For producing fine printing patterns on large seri-graphical printing frames it is possible to apply an exposure through correspondingly large film areas, but it is cheaper to make use of a successive line-by-line exposure with the use of a modulated light or laser beam, which is caused to sweep across an emulsion coated printing frame surface from an oscillating deflection mirror. The beam (20), in its outermost positions, will be directed obliquely towards the surface (14), and if the latter changes its distance from the oscillating mirror (48) the exposure lines (16) will thus be cor-respondingly shorter or longer, whereby the printing pattern may be distorted. According to the invention this can be counteracted by the light ray being brought to pass a lense beam (56) mounted just in front of the line of exposure and adapted so as to deflect, all along the line, the light beam such that it will hit the sur-face perpendicularly, whereby the length of the lines will be independent of occurring distance variations. The width of the lense beam (56) should be at least twice the line width, as the invention also provides for a transverse displacement of the light beam for achiev-ing that the latter may be delivered from a resonance-wise oscillating goniometer mirror (48) with a high operational speed without overlappings occurring between the consecutive lines of exposure.
