Patent CA-1311264-C (CA)
Title: Electrical generating plant
Inventor: WRIGHT BARTRAM J
IPC: H01M8/04014
Filed: 1985-03-11
Granted: 1992-12-08
Abstract: ABSTRACT OF THE DISCLOSURE      There is disclosed an electrical generating plant, especially for use in a submarine, having dual modes of operation and which comprises a fuel cell which requires a supply of gaseous hydrogen and a supply of gaseous oxygen in order to generate an electrical output.  First supply means supplies to the plant a hydrogen-containing compound, preferably methanol, which is liquid at NTP and which can undergo an endothermic reaction to liberate gaseous hydrogen, and second supply means is provided which is selectively operable for supplying to the plant liquid hydrogen peroxide in a first mode of operation and air in a second mode of operation.  A reformer is connected to the first supply means and causes the hydrogen-containing compound to undergo the endothermic reaction with liberation of gaseous hydrogen, whereas a decomposer is selectively connectible to the second supply means, in the first mode of operation, and is arranged to decompose the hydrogen peroxide exothermically so as to liberate gaseous oxygen.  Means is provided, preferably by means of the decomposer in the first mode of operation, for transmitting heat to the hydrogen-containing compound, prior to and/or during its reception by the reformer, so as to maintain the endothermic reaction in the reformer.  However, for the second mode of operation, separate means is provided for supplying heat to the reformer, in order to maintain the endothermic reaction.  The gaseous hydrogen given-off in the reformer is supplied to the fuel cell, in the first and second modes of operation.  Concerning the supply of gaseous oxygen to the fuel cell, this is derived from the decomposer in the first mode of operation, whereas it is obtained from an air source in the second mode of operation, whereby an electrical output is obtainable from the fuel cell in the first or the second modes of operation.  When the electrical generating plant is applied to a submarine, the plant can operate in the first mode of operation underwater, and in the second mode of operation during surface or snorting operation of the submarine.

Title: Fire extinguishing apparatus
Inventor: DAVIS CHARLES B
IPC: A62C35/00
Filed: 1987-06-08
Granted: 1991-08-13
Abstract: ABSTRACT Fire extinguishing devices are designed to extinguish specific classes of fires. The action and character of the fire extin-guishing stream are planned and fixed to combat a specific fire in a fixed state of burning.          The invention, a venturi-activated tube, extinguishes fire in it's changing states of burning, in it's stages of development and composition. The ejector-tube can discharge fire extin-guishing agents at sonic velocities to counterbalance suction flows extinguishing fire in- and through the hollow center ax s of the tube. The heat of the damaging fire regulates the optimum densities of the unified discharge- and suction flows. Pressure and suction forces combine to increase the power of this invention to put out fire.          The ejector is self-adjusting and self-cleaning. The orifice Abstract ring opens under overthrust created by driving pressures to dis-charge flow-obstructing solids automatically.

Title: Apparatus for crushing containers containing a toxic liquid
Inventor: GRIFFITH LORIN C
IPC: B02C19/00
Filed: 1988-03-03
Granted: 1993-08-31
Abstract: APPARATUS FOR CRUSHING CONTAINERS     CONTAINING A TOXIC LIQUID Abstract of the Disclosure An apparatus for crushing small containers, such as vials, containing a scintillation liquid.  The apparatus includes a closed housing having a feed open-ing in the upper end which communicates with a hopper.  The lower end of the hopper registers with a pair of cooperating crusher rolls, and the vials fed into the hopper flow downwardly through the rolls which crush or rupture the vials to permit the liquid to be expelled.  After crushing, the vials and the liquid pass through a chute and are discharged into an end of a closed vibratory conveyor unit that includes at least one vibrating screen.  The liquid passes through the screen and is collected in a container while the crush-ed vials are conveyed along the screen and are dis-charged into a collection drum.  The apparatus includes a loading basket that is pivoted to a carriage which is slidable on tracks mounted on the outer surface of the housing beneath the inlet opening.  After being filled with vials, the basket is manually raised to a position adjacent the inlet opening and is then tilted inwardly causing a door which normally encloses the inlet open-ing, to be swung to an open position to permit the vials to be fed into the hopper.  The feeding mechanism enables the vials to be fed to the crushing mechanism while maintaining a substantially sealed condition to prevent pollution of the atmosphere by fumes generated from the separated liquid.

Title: Devices and systems based on novel superconducting material
Inventor: CAVA ROBERT JOSEPH
IPC: H01F6/02
Filed: 1988-03-18
Granted: 2012-02-14
Abstract: Superconducting copper oxides of the perovskite structure are modified to have mixed occupancy of a cation site, thereby resulting in increased limits in critical field and/or critical current. Mixed occupancy may be observed in terms of increased resistivity as the superconducting material reverts to a nonsuperconducting state. A significant advantage, at least for preferred compositions, derives from the fact that critical temperature is substantially unaffected relative to the prototypical material.
