Abstract: ABSTRACT OF THE DISCLOSURE    A mechanism for generating oscillatory motion omnidirectionally transforms rotating motion in which the rotating member is continuously rotated unidirectionally into any number of simultaneous arcuate motions intersecting at predetermined angles.  This mechanism includes a disk-shaped body rotatably mounted and swept in a circle so that it completes two periods of rotation over the course of one period of sweep. The altitude of the disk-shaped body always intersects a point on an imaginary line, regardless of the angle of inclination of the disk-shaped body. This imaginary line is perpendicular to the circularly swept path of the disk-shaped body at the center of the circularly swept path.  Points on the circumferential edge of the disk-shaped body describe an infinite number of arcs as they move around the circularly swept path.  These arcs intersect at a common point from an infinite number of angles.  Any number of desired arcs intersecting at any angle can be obtained by selecting points on the circumferential edge of the disk-shaped body describing those desired arcs.  This apparatus is the basis for improvements in a variety of existing devices such as mixers, grinders, drills, pendulum devices, centrifuges, signal lights, electric shavers, massagers, scanning devices such as ultrasonic, x-ray, radar and computer memory scanners, optical cameras and projectors, dispersing devices, assembly lines, robots, energy bombardment chambers, amusement rides and educational toys.

Title: Control for automatically starting a diesel engine
Inventor: HANSON JAY L
IPC: F02N11/08
Filed: 1989-08-18
Granted: 1995-07-11
Abstract: Electrical  control  apparatus  for  automatically starting a Diesel engine.   The apparatus  includes start, preheat  and  run  relays  which  respectively  control  the energization of a starting solenoid, glow plugs and a fuel solenoid.  The energization of the start, preheat and run relays is controlled by a control module which drives the preheat relay as soon as the control module is energized. The glow plug preheat time is measured,  and the run and start relays are respectively energized just prior to, and at the termination of the preheat time.   Engine cranking time and speed are monitored, dropping the start and preheat relays when the engine starts, and also when the engine speed fails to reach certain thresholds within first and second predetermined periods of time.  The run relay continues to energize an electrical circuit which includes an engine reset switch and a low oil pressure switch.  The engine reset switch de-energizes the control module,  and thus the run relay, in the event the engine fails to start.

Title: Track roller assembly
Inventor: HASLETT GLENN M
IPC: B62D55/108
Filed: 1989-09-28
Granted: 1992-12-01
Abstract: Abstract of the Disclosure Track Roller Assembly A track roller assembly supports and guides a portion of the endless track of a track type vehicle as that portion of the track travels between a drive wheel and an idler wheel of the vehicle.  The rim portions of the roller assembly include a plurality of alternating resilient non-metallic rings and metallic rings.  The non-metallic rings are compressed between the metallic rings to increase the diameter of the outer walls of the rings.  The link rails contact the non-metallic rings only.  Conventional track supporting rollers have metallic treads which generate noise and impact against the metal link rails.  The rollers often fail to rotate due to insufficient friction with the link rails.  The subject roller assembly, with resilient rings in contact with the link rails, generates low levels of noise and vibration and produces sufficient friction to rotate the rollers.

Abstract: The present disclosure provides the complete primary amino acid, and underlying DNA, sequence for the 47-kilodalton surface immunogen of Treponema pallidum, subsp. pallidum. The-sequence was obtained by using a combined strategy of DNA sequencing of the cloned gene as well as confirmatory N-terminal amino acid sequencing of the native antigen. An open reading frame corresponding to the 47-kDa antigen was comprised of 367 amino acid codons, which gave rise to a calculated molecular weight for the corresponding antigen of about 40,701. Also disclosed are methods for preparing variant and mutant molecules having biologically similar attributes, as well as methods for preparing particular antigenic/immunogenic subportions of the 47-kDa protein. In particular aspects, antigenic/immunogenic subportions are identified by hydrophilicity analysis of the protein sequence. The 47-kDa antigen and antigenic subportions of the present invention can be used both as antigens in the detection.of clinical materials having anti-47-kDa antibodies therein, as well as in the preparation of vaccines for use in connection with promoting an immune state in vaccinated individuals. Also disclosed are DNA sequences which may be useful both in the preparation of second generation antigens, and as hybridization probes in the detection of pathogenic T. pallidum in clinical samples. Particular methods and embodiments are also disclosed which allow greatly improved recombinant DNA production of the 47-kDa antigen, including placement of the gene under the control of the T7 RNA polymerase promoter.

Abstract: A moving video image estimation system is provided, in which, when a video image occurring at an arbitrary time t between time n and time n + 1 or at an arbitrary time t after time n + 1 is produced for time  series video images  given at discrete times  1, 2, ... n, n + 1, ..., even if the position and shape of an object in the video image are considerably changed between the frames, the video image of the object in the original frame can be prevented from being reproduced doubly in the interpolated video image.    Based on an original video image of time n and time n + 1, the centroid, the principal axis of inertia, the moment about the principal axis of inertia and the moment about the axis perpendicular to the principal axis of inertia are obtained.   By using them, an affine transformation for transforming the original video image at time n to the original video image at time n + 1.    Further, based on the infinitesimal transformation (A), ?exp (At), and exp(A          (t - 1))} obtained by making the affine transformation continuous with regard to time is executed on the original video image at time n and time n + 1.   The results are synthesized to perform an interpolation between the frames.   {exp (A (t - 1))} is applied to the original video image at time n + 1, the video image after time n + 1 is predicted.
