Title: Steam reforming
Inventor: LYWOOD WARWICK J
IPC: C01B3/38
Filed: 1990-12-20
Abstract: Abstract Steam reforming A process for the production of a hydrogen containing gas stream comprises partially reforming a feed stream containing hydrocarbon feedstock to be reformed together with steam and/or carbon dioxide as reforming gas by passage of said feed stream over a steam reforming catalyst disposed in heated auxiliary tubes, thereby forming a partially reformed gas stream; subjecting the partially reformed gas stream, optionally together with a further quantity of said feedstock and/or reforming gas, to further reforming by passage over a steam reforming catalyst disposed in furnace reformer tubes heated by combustion of a fuel, thereby forming a reformed product gas stream; and passing the reformed product gas stream past the exterior of the auxiliary tubes, thereby supplying heat to said auxiliary tubes and cooling the reformed product gas stream.

Patent CA-2035105-A1 (CA)
Inventor: FREEMAN H BRUCE
IPC: G01N17/00
Filed: 1991-01-28
Abstract: ABSTRACT   An  apparatus  for measuring the diffusion  of hydrogen atoms  from a second surface to a first surface of a ferrous metal body as a means of measuring the magnitude of  corrosion  occurring  at  the  second  surface.    The apparatus comprises a chamber-defining member which can be sealed to the first surface of the body so as to define with the first surface a sealed chamber.   The chamber-defining  member  is  constructed  of  material sufficiently flexible that upon evacuation of the sealed chamber the chamber-defining member deflects toward the first  surface  to  reduce  the  chamber  volume.    The apparatus provides a connecting means for attaching an evacuating pump which is used to evacuate substantially all of the contents of the chamber.  A valve is provided to  isolate the  evacuated  chamber from the evacuation pump so that hydrogen atoms,  generated as a result of corrosion of the second surface, migrate through the body and exit the first surface within the chamber and combine to form hydrogen molecules which collect in the chamber. A vacuum gauge is provided to monitoring the decay of the vacuum in the chamber over time.

Abstract: ABSTRACT            METHOD OF AND APPARATUS FOR MONITORING            OPERATION OF A CATALYTIC CONVERTER.            Sensors measure the temperatures of exhaust gas upstream and downstream of a catalytic converter for internal combustion engine exhaust gas.  The difference between the temperatures is multiplied by the rate of mass flow of exhaust gas and the result is integrated or low pass filtered to provide a measure of converter operation. Alternatively, the multiplication is omitted and the difference between the temperatures is integrated or filtered.

Title: Plant transformation process with early identification of germ line transformation events
Inventor: CHRISTOU PAUL
IPC: C12N15/82
Filed: 1991-02-22
Abstract: ABSTRACT      A method is disclosed for making more efficient the particle-mediated germ line genetic transformation of bean species such as soybean.  After a particle mediated transformation event, in the absence of a selectable marker gene, relatively large numbers of plants must be regenerated to find the relatively low likelihood germ line transformation events which have occurred.  It has been discovered that using in the transformation process a marker gene, linked to the gene of interest, and by excising a segment of the stem of the shoot during the regeneration process and assaying the segment for the marker gene, certain patterns or phenotypes can be identified in the stem segment which are associated with an increased frequency of germ line transformation events.  As the plants are regenerated, other indices of gene expression, at the first trifoliate leaf stage and at the third or fourth trifoliate leaf stage, also serve as markers of the likelihood of germ line transformation.  By using these markers in the relatively early stages of plant regeneration to assay for likelihood of germ line events, it is possible to concentrate regeneration efforts on plants most likely to yield germ line events, and to discard the others, so as to lower the burden and effort in achieving a desired number of transformation events.

Abstract: An electrical machine having a stator formed from a pair of cup-shaped permanent magnets symmetrically disposed on opposite sides of a conductive, disk-shaped rotor. The magnets are polarized such that a portion of their external magnetic flux passes in one direction through a short peripheral gap formed by the magnets in which the periphery of the rotor is disposed. The remainder of the external magnetic flux substantially passes in the opposite direction through a cavity defined by the inner volume of the cup-shaped magnets. The inner portion of the disk-shaped rotor is disposed in this cavity. One embodiment of the invention implements the cup-shaped magnets with modified "magic spheres" mounted on either side of the conductive disk-shaped rotor. Other embodiments use a magnetic plate on one side of the disk-shaped rotor to act as a magnetic mirror for a cup-shaped magnet mounted on the other side of the rotor. In still another embodiment, the magnets are mounted as rotors while the conductive disk is the stator. The machine may be used as a homopolar generator or a homopolar motor,

Abstract: A release mechanism for facilitating launching a spin-stabilized self-propelled missile, which includes a rotary missile support and a launching support for support-ing the rotary missile support for rotation about a spin axis and for movement axially of the spin axis.  A nozzle assembly extends between the rotary missile support and the missile coaxial with the spin axis.  A separable portion of the nozzle assembly moves axially in an aft direction under the influence of exhaust gases expelled by the missile. The separable portion strikes an abutment on the rotary missile support to effect rapid movement of the rotary missile support axially away from the missile on separation of the separable portion of the nozzle assembly.   A low friction bearing is provided for engagement by the rotary missile support at its aft limit position of travel away from the missile to reduce spin momentum induced forces caused by the rotary missile support.  Another low friction bearing surrounds the rotary missile support between the support and the launching support to further reduce spin momentum  induced forces.   A time release mechanism is provided for preventing aft movement of the rotary missile support during a given number of initial revolutions and for releasing the rotary missile support to  allow aft movement thereof after the given number of initial revolu-tions.   A prescribed clearance is provided between the missile  and  the  launching  support  to  prevent  post-separation collisions between the missile and the launching support.
