Title: Heating vessel construction
Inventor: YIGDALL JEFFREY S
IPC: C03B3/02
Filed: 1987-10-06
Granted: 1990-11-27
Abstract: Abstract The circulation of exhaust gas within a heating vessel is controlled to reduce the adverse effects of the abrasive and corrosive exhaust gas on exposed interior surfaces of the vessel.  The firing rates of the burners in the vessel may be varied to alter the flow patterns within the vessel.  Additional jet burners with high exhaust gas velocity may be used to direct their exhaust flow in a direction opposing the exhaust flow of other selected burners.  Burners may also be angled so as to reduce the flow component of the exhaust gas that may pass over the exposed interior surfaces of the vessel.

IPC: C12N15/87
Filed: 1987-11-20
Granted: 1998-06-09
Abstract: A method and apparatus is disclosed for the genetic transformation of plants and plant lines by pollen mediated transformation.  Foreign genes are introduced into pollen by coating on carrier particles which are physically accelerated into plant pollen.  The treated plant pollen is then hand pollinated and the progeny are recovered, a portion of which will contain in their genome the foreign gene.  The procedure may be used to create genetically engineered maize plant and lines.

Abstract: (57) Abstract The invention relates to a method and apparatus for separating knots. Especially the method and the apparatus are meant to be adjusted in separating knots from the fibre suspensions of wood processing industry. According to the prior art a problem acknowledged has been the quick wear of the screen surface of the knotter when the screen surface has been profiled. On the other hand the ability to separate with the unprofiled screen has been unsatisfactory. When using a profiled screen cylinder (5)  it has been noticed in the performed tests to be most prefarable to feed the pulp from the connections (2)  in the direction of rotation of the  screen cylinder and also to discharge the reject from the connections (4) and the accept from the connections (3) of the cylinder (5) in the direction of rotation. A result from this is not only lesser wear of the screen surface, but also a significantly smaller consumption of power per pulp ton than in the apparatuses in accordance with the prior art.

Title: Mandrel for making elastomeric articles
Inventor: PRATER RONALD E
IPC: B29C41/40
Filed: 1988-03-07
Granted: 1993-06-01
Abstract: ABSTRACT   A one-piece mandrel for making elastomeric articles by a dipping process has a one-piece body which includes at least one opening extending therethrough.  A split extends from the opening through a cross-section of the one-piece body.  At least a portion of the body adjacent the split is formed of an elastically resilient material to allow the split to open for removal of the elastomeric article after formation, and to cause the split to self-close after removal of the article from the mandrel.  Closure of the split forms a substantially continuous molding surface in the immediately vicinity of the split.  Proper alignment of the mating surfaces of the split is assured by irregular (non-planar) design of the split surfaces, or by use of an alignment element embedded in the mandrel.  In embodiments where a ferro magnetic alignment element is used, a separate magnetized element may also be embedded in the mandrel to assist in holding the split closed during the dipping process.  If necessary or desired, both elements may be magnetized.  An especially advantageous material for forming the mandrel of the present invention is an elastomeric composition having a Shore A hardness ranging from 20-90 (preferably 60-75), a tensile strength ranging from 500-1,100 pounds per square inch, a percentage elongation of 150 360%, a tear strength of 55-120 pounds per square inch, and a continuous surface temperature equal to or greater than 212°F.

Granted: 1991-03-26
Abstract: ABSTRACT:      With this arrival regulating equipment,  the difference, which arises between actual speed value and     target speed value on the transition from an unregulated phase of the travel to the regulated braking phase, can not come into effect so that the travel comfort is not impaired and the stopping accuracy remains assured.  For this purpose,  a factor is formed from the actual speed value and  an assoc-iated nominal speed value by means of a divider (21) during the travel phase before the onset point of braking and stored during  the braking phase in a storage equipment (23).   Stored in a travel curve store (20) are travel-dependent target speed values (vs), which are multiplied by the factor by means of a multiplier (24) and conducted as target speed values (vs') to a speed regulating circuit during the braking phase.

Abstract: Abstract of the Disclosure A first delay circuit delays a digital composite color video signal by a one-scanning-line time.  A second delay circuit delays the output signal of the first delay circuit by the one-scanning-line time.  A first correlation detector detects a correlation between the digital composite color video signal and the output signal of the first delay circuit.  A second correlation detector detects a correlation between output signals of the first and second delay circuits.  A coefficient gen-erator generates first and second coefficients corre-sponding to magnitudes of the correlation-detect outputs of first and second correlation detectors.  A first difference-signal detector detects a difference signal of the digital composite color video signal and the output signal of the first delay circuit.  A second difference-signal detector detects a difference signal of the output signals of the first and second delay cir-cuits.  A first weighting section weights the difference signal from the first difference-signal detector with the first coefficient provided from the coefficient generator.  A second weighting section weights the difference signal from the second difference-signal detector with the second coefficient provided from the coefficient generator.  A chrominance signal component outputting section adds together output signals of the first and second weighting sections to separate and output a chrominance signal component contained in the digital composite color video signal.
