Abstract: TRACTOR TRANSMISSION    ABSTRACT OF THE INVENTION          A drop box transmission is especially suited for use  in heavy  equipment  of  the  four-wheel  drive, bi-directional Type 1, that is capable of being driven in opposite directions with equal speed and power ranges. The transmission has a four shaft drop from an input shaft carrying high and low range gears alternatively driving a second shaft positioned below the input shaft. A series of gears mounted rotatably on the second shaft are in constant mesh with compatible gears on a third shaft below the second shaft.  The second shaft gears are selectively and alternatively engaged with the  second shaft to be driven by it.  Each of these gears is in con-stant mesh with a corresponding gear rotating with a third shaft below the  second shaft.   The third shaft drives a drive gear meshing with a forward drive gear on a fourth,  output shaft below the third shaft and also drives a gear on a reversing counter shaft carrying a second  gear  meshing  with  a  reverse  drive  gear  also carrier on the fourth shaft.   The forward and reverse drive gears are rotatable on the fourth shaft and are alternatively coupled to it to provide final drive to the fourth shaft.

Abstract: A method for operating an ion mobility spectrometer in which an analyte sample is ionized in the spectrometer reaction chamber, and the analyte ions are permitted to flow freely from the reaction chamber into the spectrometer drift chamber. The ion current output from the spectrometer ion current detector is observed during this time. The ion flow from the reaction chamber to the drift chamber is then momentarily interrupted, and the time delay between the time of ion flow interruption and the appearance of a decrease in the ion current detector output is observed. Difference substances are characterized by different delays. The concentrations of the different substances may be determined by measuring the change in detected ion current after the ion flow interruption.

Title: Method and apparatus for the direct reduction of iron
Inventor: DAM G OSCAR G
IPC: C21B13/04
Filed: 1990-04-10
Abstract: A process for the direct reduction of iron-containing metal oxides to obtain iron is disclosed in which a reformed reduction gas rich in H2 and CO and having an oxidation degree in the range of from about 0.30 to about 0.35 is formed and reduction is carried out simultaneously in a single reaction zone of a reduction reactor.

Filed: 1990-08-16
Abstract: Abstract The present invention is directed to a method for producing a porous preform for use in the fabrication of an optical fiber.  The method uses at least two burners for synthesizing glass soot particles at least one of which generates a double-layer flame having an inner flame and an outer flame and at least one of which is used for forming a core part of the preform.  The method comprises the steps of supplying SiC14 and optionally GeCl4 to the inner flame of the double-layer flame, and SiCl4 to the outer flame of the double-layer flame to flame hydrolyze the supplied compounds to synthesize glass soot particles, supplying SiCl4 and GeCl4 as glass-forming raw materials to the burner for forming the core part to flame hydrolyze the supplied compound to synthesize glass soot particles and depositing the generated glass soot particles on the lower end of a rotating starting member and drawing the porous preform in the direction of the axis of the starting member to produce a porous preform comprising a core part containing at least partly GeO2.  A porous preform produced by this method gives a transparent glass preform the surface of which is not cracked or peeling.

Title: Pellet burner appliances and burners therefor
Inventor: JURGENS HEINRICH J W
IPC: F23K3/14
Filed: 1991-08-28
Abstract: ABSTRACT OF THE DISCLOSURE           A pellet burning appliance with an improved burner is disclosed.  This improved burner includes an open ended retort in communication with a feed auger at the inlet end opposite the open end.  The feed auger delivers solid fuel pellets through the inlet end which results in underfeeding action and cross-flow of the combustion bed.  An air hole arrangement introduces primary and secondary air for highly efficient burning. The floor of the retort is flat, and colinear with the bottom of the auger tube.  The burner is inclined within the appliance at approximately 22.5) from the horizontal. This design promotes efficient burning as the constantly fed fuel spreads evenly whereby it combusts over substantially the entire length of the retort.  The feeding action continually pushes clinkers and other combustion inhibiting particulates, in an unobstructed manner, off the retort's terminal end.

Title: Method for preparing multi-layered ceramic with internal copper conductor
Inventor: TAMHANKAR SATISH S
IPC: C04B35/64
Filed: 1991-09-19
Abstract: ABSTRACT            A method for heat processing of multilayered ceramic articles containing internal conductive metal patterns that have been formed from multiple ceramic green sheets individually coated with inks or pastes containing conductor metal/metal oxide material, and thereafter assembled in registry with each other and laminated.  The heat treating method to convert the laminate to the final ceramic article comprises a first heating stage under conditions to promote burn-out of the organic polymeric binder present, a second stage performed under conditions to reduce the metallic conductor, and a third stage to sinter the multilayered composite to form the final ceramic article.  The invention is characterized by the presence of moisture in an amount of from about 0.5% to about 3% of the gaseous atmosphere in at least the sintering stage, and preferably at both the binder burn-out stage and the sintering stage.  Multilayered articles heat treated under these conditions exhibit a combination of improved properties, including little or no staining in combination with improved conductivity and dielectric properties.  In a preferred embodiment, the present method may be performed as a continuous process without the need for cool-down and heat-up of the laminate, in a continuous furnace with an atmosphere that is microprocessor-controlled.  Optional catalytic generation of the moisture containing heating atmosphere may be utilized to further reduce cost and processing time while increasing process efficiency and productivity.
