Abstract: ABSTRACT A marker for concrete safety barriers incorporates a hollow, cylindrical body which is bifurcated from one end to define spaced-apart diverging legs, and an end wall on the other end.  Inner walls close the legs and allow them to define pockets which can receive granular material.  A reflective sheet material can be affixed to at least part of the exterior.  All parts are made of deformable materials such as linear, low-density polyethylene.

Abstract: An antenna in a transponder receives signals from a reader, modulates them, and reflects them back to a reader to pass the information contained in the transponder to the reader.  The system includes a thin planar dielectric material having first and second opposite surfaces, preferably with the approximate dimensions of a credit card.  First conductive material is disposed on the first surface of the dielectric member at a first end of the member.  Second conductive material on the second opposite surface of the dielectric member at the second end of the member defines a dipole with the first material.  The second material, preferably triangular in configuration, extends from the second end to a median position between the opposite ends.  Preferably the triangular configuration is defined by a base extending substantially the width of the dielectric member and by an apex at the median position.  An electrical circuitry module on the dielectric member produces reflected signals modulated at a particular frequency from the signal transmitted by the reader to pass information contained in the transponder to the reader.  The third conductive material on the second surface of the member is electrically coupled with the second conductive material and extends from the triangular apex toward the first end to enhance an impedance match between the dipole and electrical circuitry.  The third material has a first low impedance portion split into two parts connected in parallel to provide an extended effective length in a relatively small distance, and has a second portion, preferably a "pigtail" of substantially higher impedance than the first portion connected in series with the first portion.  The first portion converts the antenna impedance to a low value and the second portion converts the low impedance to the impedance of the electrical circuitry module.

Abstract: ABSTRACT OF THE DISCLOSURE             A method for forming an abradable composite material and  the material so formed.  A filler is fed axially into a stream of high-temperature combustion gases such that the filler is  entrained  in  the  gaseous  stream.   The  gaseous  stream containing the filler is then used to atomize the molten tip of a metal wire which is continuously fed into the gaseous stream. The resultant gaseous stream which contains both the filler and the  atomized molten metal  is  directed  to  the  surface  of  a target.  The filler and the molten metal impact the target and combine to form a substantially continuous metal matrix in which the  interstices  are  filled  by  the  filler.   The  composite material abrades readily upon frictional contact with a moving part.

Abstract: ABSTRACT      An incident radiation sensing apparatus comprises an array of photosensitive elements formed as an integrated circuit on a substrate. Each of the photosensitive elements includes a capacitor for storing charge, a conductive means for charging the capacitor to a preselected magnitude, a blocking means for inhibiting the discharge of charge stored on the capacitor; and a photoresponsive means formed from deposited semiconductor material for generating charge carriers at a rate responsive to the intensity of radiation incident upon the photoresponsive means. The photoresponsive means is connected to the capacitor so that the charge carriers generated in the photoresponsive means reduce the magnitude of the charge on the capacitor as a function of the magnitude of, and the time incidence of, the incident radiation.     The apparatus further includes means for sensing the magnitude of charge remaining on the capacitor of a given photosensitive element a preselected period of time after its charging by the conductive means, so as to produce a signal corresponding to the time integral of the magnitude of the incident radiation impinging on the photoresponsive means connected to that capacitor during the preselected period of time. The present invention includes using such a radiation sensor in x-ray images, contact-type document copiers, and electronic cameras.

Abstract: The Invention relates to a process of increasing the solids content of black liquor at its recovery in a sulfate pulping process. According to the invention, the liquor is first heated at a presure which is so high that no boiling occurs at the heating temperature, after which the liquor is led to a tank where its pressure is released to a value below the saturation pressure of steam at the relative temperature of the liquor such that water is evaporated. The liquor thus concentrated can be led to the liquor combustion in the recovery process.
