Title: Caster wheel control apparatus
Inventor: KARCHEWSKI JOHN
IPC: A01M7/00
Filed: 1988-07-20
Granted: 1992-08-04
Abstract: ABSTRACT OF THE DISCLOSURE         In general, the remote control of a caster wheel assembly on a farm implement such as a crop sprayer of the type including a boom rotatable between a transport position and a field position is a complicated operation.  In the transport position, the wheel assembly should be fixed, i.e. non-castering and in the field position the wheel assembly should caster freely.  A relatively simple apparatus for effecting caster wheel assembly control includes a frame mounted on the boom, a hydraulic cylinder on the frame, and a linkage connected to the piston rod of the cylinder and releasably connected to an arm on the shaft carrying the wheel assembly, whereby initial extension of the piston rod moves the wheel assembly to a turning position, full piston rod extension causes release and thus free castering of the wheel assembly in the field position, and retraction of the piston rod causes re-engagement of the wheel assembly by the linkage to lock the wheel assembly in the transport position.  In the turning position, the wheel is at an acute angle with respect to the longitudinal axis of the boom.  With such an arrangement the boom can be moved into the field position by moving the implement a relatively short distance of 100 feet, instead of the 200 - 300 yards normally required.

Granted: 1992-07-07
Abstract: ABSTRACT OF THE DISCLOSURE         A solid state microscope for viewing and scanning microscopic objects.  The solid state microscope has a light source with a condensor and diffusion filter. A moveable stage is provided to allow X, Y, Z plane displacements in order to scan objects under the microscope.  There is an objective to magnify the image of the object and project this image onto a two dimen-sional solid state image sensor.  the solid state image sensor sends signals to an analog-to-digital converter where the signal, are digitized and sent to a frame memory.  A monitor is used to display the image of the object as stored in frame memory.  The present invention can be interfaced with a computer to allow for automatic focusing and scanning of an image.  The computer also houses storage means to store image.  Methods of scanning an object are also described.  A prism element can be used to obtain sepctral scans of an object.  In another scanning method, a first edge row of pixels is used to detect an object of interest in the scanned image.  This first detection row activates an area of the sensor array at a-later time to capture the entire image. In this way, only relevant information is collected and processed.

Abstract: ABSTRACT The present invention relates to a process for polymerizing olefins.          In the process of the present invention, olefins are polymerized using a catalyst composed of a compound of a transition metal (e.g. zirconium) of Group IVB of the periodic table, an aluminoxane produced from tri-methylaluminum, and an aluminoxane wherein at least one hydrocarbon group other than n alkyl groups is bonded to an aluminum atom.  The present process can polymerize olefins with excellent polymerization activity and can produce an olefin polymer having a relatively large molecular weight even when the use amount of the aluminoxane produced from trimethylaluminum (which is expensive) is small.

Abstract: AXIAL SEALING MECHANISM FOR A SCROLL TYPE COMPRESSOR          ABSTRACT OF THE DISCLOSURE This invention discloses an axial sealing mechanism for axially seal-ing an orbiting scroll and a fixed scroll of a scroll type compressor. The compressor includes a driving mechanism for driving the orbiting scroll in an orbital motion and a block member fixedly attached to the housing of the scroll compressor to support the driving mechanism. The block mem-ber and the fixed scroll define an intermediate chamber in which the orbit-ing scroll is disposed. The intermediate chamber is divided into a first and second chamber by an end plate of the orbiting scroll. A first conduit, which is sized to produce a pressure throttling effect, links the second chamber and the discharge chamber of the compressor to increase the pressure in the intermediate chamber. A second conduit, which also is sized to produce a pressure throttling effect, links the second chamber to the suction chamber of the compressor. During operation of the compres-sor, the second chamber is maintained at an intermediate pressure without pressure fluctuation due to the presence of the first and second conduits. This intermediate pressure provides a constant urging force against the orbiting scroll to urge it against the fixed scroll to obtain a good axial seal between both scrolls without decreasing the durability of the driving mech-anism and the rotation preventing mechanism.
