Abstract: ABSTRACT OF THE DISCLOSURE:           A process for energy recovery from solid fossil fuels containing inert material by conversion of these fuels into gases, the process comprising the steps of:  supplying the fuel to a pressurised fluidised bed reactor, burning the fuel in the reactor in association with compressed combustion air also supplied to the reactor, thereby generating flue gases in the reactor, and sharply cooling the flue gases inside the reactor by heat exchange with at least one fluid passed through the reactor.  Thereafter, cleaning the cooled flue gases under pressure to remove harmful substances, and passing at least a portion of the cooled and cleaned flue gases through the fluidised bed of the reactor to reheat the cooled flue gases.  Afterwards, conducting the cleaned and reheated flue gases to a gas turbine driving a compressor for the compression of the combustion air for supplying to the reactor, passing the compressed combustion air to the reactor in countercurrent gas-gas heat exchange relation to the reheated flue gases, conducting water to the reactor to generate steam and to cool the flue gases before they leave the reactor, and passing the steam to a steam turbine.  And, an apparatus to carry out this process.

Abstract: Lung Surfactant Compositions Abstract A synthetic protein-free lung surfactant composition is utilized to temporarily substitute for natural lung surfactant in the mammalian lung where such natural lung surfactant is absent or in low concentration.  The synthetic surfactant composition consists essentially of a major amount of 1,2-dipalmitoyl-sn-3-glycerophosphoryl choline (DPPC), and a minor amount of a fatty alcohol, preferably a fatty alcohol having from 14 to 18 carbon atoms, and especially n-hexdecan-l-ol.  The synthetic surfactant composition is administrerd directly into the lungs of a distressed subject to create a film on the alveolar interfacial surfaces and reduce suraface tension.  Expansion of the alveolar spaces is thereby facilitated.

Abstract: APPLICATION FOR CANADIAN LETTERS PATENT             INVENTOR                        FRANK FIEDLER, JR.              TITLE                      SAFETY SHUT-OFF VALVE                   ABSTRACT OF THE DISCLOSURE The invention is a pressure responsive shut-off valve including a valve housing that defines a fluid inlet and a fluid outlet separated by a valve seat. A valve closure accommodated by the valve seat moves between the inlet and outlet. Controlling the valve is a valve operator including a pressure responsive piston that moves between a set position in which the valve closure is separated from the valve seat and a release position in which the closure is seated on the seat to prevent fluid flow between the inlet and outlet. Retaining the piston is a cylinder body that defines an activating volume communicating with the inlet and establishing on one face of the piston a fluid pressure forcing the piston toward its release position, and a reference volume communicating with the inlet and estab-lishing on the opposite face of the piston a reference volume. An internal seal isolates the inlet from the reference volume with the piston in its set position while allowing fluid communication therebetween with the piston in its release position.  Maintaining the piston in the set position is a latching mechanism that, after activation of the piston to its release position by excessive pressure, can be restored by a manual reset.

Abstract: W.Moore - 4 LUMINAIRE FOR ROADWAY LIGHTING                     ABSTRACT     A luminaire of otherwise conventional design for street or roadway outdoor lighting which employs as its structural housing, members fabricated of suitable plastic material. The slipfitter structure and the base member on which the weighty, electrical components are mounted is made of material having superior tensile strength such as cast aluminum. The aluminum base member is fitted closely and secured to the plastic housing. Thus, the portion of the luminaire most subject to stresses is aluminum while for the larger exterior areas suitable molded plastic may be used. The contours of the aluminum base member form an arched structure for supporting the comparative light weight but physically bulky upper plastic housing. By this construction, the plastic housings are placed in compression but all tensile forces are applied to the base member. In this way the plastic housing merely forms a protective shroud for the luminaire.

Abstract: ABSTRACT A free piston engine pump (FPEP) converts combustion energy into hydraulic power in an efficient, controlled and relatively uncomplicated manner, for example, for vehicle propulsion, auxiliary system power, etc. The FPEP is substantially naturally mass balanced having opposed engine pistons driving respective in-line hydraulic pumps. An adjustable accumu-lator with a deformable fluid-tight chamber containing a compressible fluid stores and delivers energy for compression, and an arrangement of control valves and check valves enables selective operation of the FPEP in primary (high flow) and secondary (high pressure) modes. Plural FPEP's may be interfaced for parallel operation sharing common elements and functions. Cycle rate, intermittent operation and start-up also may be controlled. Electronic monitoring and control of one or more operational parameters of a FPEP also are disclosed.

Abstract: THE ABSTRACT OF THE DISCLOSURE         A safety device for use in a solid fuel fired heating system with an airtight combustion chamber having a primary air feed duct with a primary air valve closeable to a minimum opening, and an exhaust duct for waste gases.  The device comprises a 100% shutdown valve means through which air being fed to the combustion chamber must pass.  A means is provided to hold the 100% shutdown valve means normally in open position.  Also a means is provided to close completely and automatically the 100% shutdown valve means upon occurrence of a predetermined condition.  Depending upon the application that means may be a fusible link, a pressure or thermostatically controlled switch, and/or a solenoid or motor means actuable upon interruption of line current, used independently or in combination with each other, to cause closing of the shutdown valve.          Closing of the air flow feed completely, by closing of the shutdown valve, will put an end to all further combustion within the heating device or extinguish a flue fire.  Such device meets requirements of listing agencies that prohibit the user from restricting air flow feed completely to the combustion chamber of such solid fuel fired heating devices, while at the same time permitting the safety feature of enabling complete shutdown of the unit when specific conditions arise.

Abstract: ABSTRACT   Scanning apparatus having at least one self scanned array, together with processors for processing line, halftone or continuous tone images. A multi-speed transport carries documents to be scanned past a scanning slit where the moving document is scanned line by line by the array. Normally, scanning is carried out in high speed on the assumption that most documents are composed of lines or text and the resulting image signals processed by the line processor. During scanning, halftone and continuous tone detectors look for halftone and continuous tone images. Where halftone is found, the line is immediately rescanned at low speed and the image signals processed by the halftone processor. Thereafter, the apparatus reverts to high speed scanning. Where continuous tone images are found, the document page is rescanned at low speed with the image signals output by the scanning array processed by a continuous tone processor. To enhance operation, sub-sampling of the document page may be employed on the first high speed scanning pass.
