Title: Method for making knotless bead bundle, a bead bundle made thereby and a tire incorporating said bead bundle
Inventor: SHEMENSKI ROBERT M
IPC: B60C15/04
Filed: 1990-08-10
Abstract: Abstract of the Disclosure METHOD FOR MAKING KNOTLESS BEAD BUNDLE, A BEAD BUNDLE MADE THEREBY, AND A TIRE INCORPORATING SAID BEAD BUNDLE     A method for making a knotless bead bundle, a bead bundle made according to the method, and a tire made using the knotless bead bundle are provided.  In the method a bead ring is made using a plurality of annular turns of wire as is conventional in the art, and the annular turns of wire are wrapped with cord, tape, or other conventional wrapping material which is held on the bead ring without using knots.  The wrap is held on the bead ring by using a tie down area that is made by forming a loop in the wrapping material, holding the loop in place by a number of close turns of wrap on the bead ring while leaving a first end of the wrapping material free, wrapping the bead ring 360° around the ring, passing a second end of the wrapping material through the loop, closing the loop by pulling the first end of the wrapping material whereby closing the loop pulls the second end of the wrapping material under the close turns of wrapping material.  The ends of the wrap are then cut flush with the close turns of wrap. A tire made using the bead bundle of the invention demonstrates improved uniformity, stability and durability.

Title: Tire composter
Inventor: ANANI RIAD M
IPC: C05F17/02
Filed: 1990-10-05
Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides composters comprising used tires. Three main types of tire composters are discussed in this disclosure. These types are: simple tire composters, generally indicated as 100; more advanced tire composters provided with aeration and compost-gas scrubbing options for speeding up the composting process and reducing foul smell, generally indicated as 200; and tire-stack composters, also provided with aeration and compost-gas scrubbing options, generally indicated as 300. Other tire composter types, of less dominance in this presentation, are also discussed briefly. Each type may include a family of a wide variety of tire composters having similar general structure, but different in specifics such as shape and positioning of composter components, and number of tires utilized. While sharing the same novel idea of using tires to build composters, each tire composter type is distinguished from others in the degree of sophistication, cost, and performance.

Filed: 1991-04-16
Abstract: A print engine including a two-dimensional matrix print head is operated by data signals from a raster image processor through a distributed digital controller having a master controller and a plurality of separate controllers each for a separate set of elements along one of the dimensions of the array, specifically the finger control electrodes of an ion projection printing head. The elements along the other dimension of the array (the RF electrodes of the ion projection head) are controlled by the master controller which also controls the timing of writing of the pixel data signals into memories associated with each of the distributed controllers and the timing of the readout of the pixel data to the finger control electrodes in synchronism with the activation of the RF electrodes and the movement of a medium on which the image is printed in synchronism with each other so as to print portions of each line in sequence (interleaving dots representing pixels on each line) to form the image on the medium.      The pixel data is in the form of digital grey-scale data words representing the grey scale or density of the pixels. The distributed controllers have counters which are preset by the grey-scale data words and deliver pulses of duration (a pulse width modulated output) which varies the density or grey scale of the dots.

Title: Methods and apparatus for quantifying tissue damage
Inventor: YOUNG WISE
IPC: G01N33/84
Filed: 1990-08-13
Abstract: Tissue damage may be quantified, tissue type identified, neural activity monitored or blood hematocrit determined by mea-suring the difference between the total tissue sodium and potassium concentrations in the area in question. Comparison of these measurements with standard values permit evaluation of the amount of tissue damage in cells of the same type or the tissue type in non-necrotic cells. Evaluation over time of normal brain cells permit monitoring of neural activity. By directly and simultane-ously measuring sodium and potassium ion concentrations, for example, a nuclear magnetic resonance spectrometer can image areas of different tissue type in differing colors. In this manner tumors and lesions can be clearly delineated. Measurement of to-tal potassium concentration of a blood sample and the potassium concentration of the cell-free plasma will permit determination of cellular volume fraction (hematocrit).
