Patent CA-2105484-A1 (CA)
Title: Trailer stabilizer and method
Inventor: HAWKINS WALLACE H
IPC: B62D53/08
Filed: 1993-02-19
Abstract: A stabilizer for a multi-trailer rig has a cylinder assembly including a cylinder (A) and a piston rod (E) pivotally mounted between a front trailer (11) on one end and a wheeled dolly (10) at H  exerting a force which at all times is in a direction tending to bring the dolly (10) into alignment and thereby bring a rear trailer (12) which follows the dolly (10) into alignment. A pair of such cylinder assemblies may be provided with each having a central stop member (B) carried internally of a cylinder (A) with pistons (C and D) on each respective side for effectively moving to pull or to push until such action may be reversed following engagement of a piston (C or D) with the central stop member (B).  Exerting control over alignment of the dolly (10) stabilizes the trailers and continues to exert a force to maintain alignment, yet permits turning. A locking clutch member (I) may be manually fixed to limit movement of the cylinder (a) and piston rod (E) thereby preventing the dolly (10) from coming out of alignment during backing. An anti-jackknifing apparatus includes a stop (j) pivoted downwardly from the trailer into the slot of the tractor fifth wheel.

Title: A process for the synthesis of silyl alcohols
Inventor: CELEBUSKI JOSEPH E
IPC: C07F7/08
Filed: 1992-06-05
Abstract: Novel silyl alcohols having bulky substituents bonded to the silicon, and the silyl group attached to a carbon include the preferred 2-silyl-ethan-1-ols. A method for synthesizing silyl substituted alcohols include hydrosilation of a vinylic ester, especially vinyl acetate, followed by hydrolysis in mild base. The silyl alcohols are useful in preparing phosphorylating reagents for phosphorylating an oligonucleotide. The phosphorylated intermediate bearing the silyl group may be separated from failure product on the basis of bulky substituents on the silyl protecting group, which is later removed, e.g. by fluoride ion.

Title: Methods and apparatus for measuring tissue section thickness
Inventor: BACUS JAMES W
IPC: G06T7/60
Filed: 1993-10-14
Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus and method for measuring the thickness of a tissue  section with  an automated  image analysis  system, preferably using polyploid nuclear  DNA content,  for use subsequent use in analyzing cell objects of a specimen cell sample for the diagnosis and treatment of actual or suspected cancer or monitoring any variation in the nominal thickness in a microtome setting is disclosed.  An image of a measurement material, such as a rat liver tissue section, having known cell  object  attributes  is  first  digitized  and  the morphological attributes, including area and DNA mass of the cell objects, are automatically measured from the digitized image.   The measured attributes are compared to ranges of attribute values which are preestablished to select particular cell objects.  After the selection of the cell objects, the operator may review the automatically selected cell objects and accept or change the measured cell object attribute values.  In a preferred embodiment, each selected cell object is assigned to one of three classes corresponding to diploid, tetraploid and octoploid cell morphology and the measured DNA mass of the identified cell object fragments in the rat liver tissue section sample may be corrected.  Next, the selected cell objects of the measurement material, e.g., DNA Mass, are then graphically displayed in a histogram and the thickness of the rat liver tissue section can be measured based upon the distribution.

IPC: B01D53/50
Filed: 1994-01-27
Abstract: A method of saturating and humidifying the incoming flue gas of a flue gas desulfurization process without the need for underspray headers or the like. Initial humidification occurs by passing the incoming flue gas through a continuous liquid curtain of recycled bottoms product falling from an awning over the flue gas inlet. Further saturation and humidification occurs by causing recycled bottoms product to fall or rain from an overhead tray or grid onto the flue gas prior to passing through the tray or grid. In order to accomplish such humidification, there is an unobstructed passageway between the flue gas inlet and the lowermost tray or grid.

Title: High frequency vacuum tube with closely spaced cathode and non-emissive grid
Inventor: SHRADER MERRALD B
IPC: H01J23/46
Filed: 1994-05-31
Abstract: A vacuum tube for handling an r.f. signal having a predetermined frequency range comprises a linear electron beam emitting cathode, a heater and a non-electron emissive current modulating grid. The grid is positioned from the cathode by the distance an emitted electron from the cathode can travel in a quarter cycle of the r.f. signal. Outer and inner coaxial metal tubes forming a resonant line of a signal coupler are respectively connected to the grid and cathode so electrons passing through the grid are in bundles in an interaction region between an accelerating anode and the grid. Ferrite tiles absorb r.f. fields in the interaction region. In one embodiment a signal coupling loop is between metal tubes at an end of the tubes spaced 3.lambda./4 from the grid and cathode. In a second embodiment the coupler includes a low voltage coaxial line having an inner conductor connected to a first metal face, spaced from a second opposed metal face by a solid dielectric. The coaxial outer conductor is connected to a third metal face, spaced from a fourth opposed metal face by the solid dielectric. The third and fourth faces surround the first and second faces. The first and third faces are at DC ground potential while the second and fourth faces are at high negative- DC voltages. The second and fourth faces are respectively at common ends of interior and exterior coaxial metal tubes forming a .lambda./2 coupler. Other ends of the tubes are connected to the cathode and grid. Bias leads for the grid and cathode are connected to the exterior and interior tubes at positions .lambda./4 from the grid and cathode, while a heater lead goes through the interior tube at a position .lambda./4 from the grid and cathode.
