Abstract: ABSTRACT         An apparatus for and method of adjusting the effective length of a rotary kiln.  Preheating gas enters the kiln, passes over a portion of the material to be heated and exits the kiln through an axially extending exhaust duct.  Changing the length of the duct modifies the amount of time the material is subjected to direct heating by the gas so that the effective heating length of the kiln is changed.

Abstract: ABSTRACT OF THE DISCLOSURE    A machine for felling standing trees,  cutting logs into segments of the desired length and splitting logs lengthwise.  A shear blade is mounted for reciprocal movement within a framework by means of a hydraulic cylinder or cylinders so as to urge the log against an anvil at the rear of the frame upon the forward cutting stroke.   The frame is pivotably affixed to the drawbar lift assembly of a tractor so as to be rotatable between a horizontal attitude for felling standing timber and a vertical or upright attitude for cutting and splitting logs.   The anvil is pivotably connected to the frame,  and includes an operating mechanism whereby it can be swung open to admit a standing tree and then closed and latched to sever the tree.  The cutting edge of the shear blade is in the form of a V-shaped notch so that the log is stabilized while being severed in opposed directions upon the forward, cutting stroke.   A saddle moveable along the frame with the shear blade laterally stabilizes the blade and, upon retraction of the blade, dislodges logs which may become stuck thereon.

Title: Personal health monitor
Inventor: FU PING W
Filed: 1987-06-12
Granted: 1991-12-10
Abstract: ABSTRACT OF THE DISCLOSURE A personal health monitor includes sensors for measuring patient weight, temperature, blood pres-sure, and ECG waveform.  The monitor is coupled to a central unit via modems and includes a computer which is programmed to prompt a patient to take prescribed medication at prescribed times, to use the sensors to measure prescribed health parameters, and to supply answers to selected questions.  Medication compliance information, test results, and patient answers are compiled in a composite log which is automatically transmitted to the central unit.  The computer is also programmed automatically to disconnect the monitor from an alternating current power source and to rely on internal battery power during certain periods of patient-monitor interaction, such as during use of the ECG module.  In this way, danger to the patient and complexity of the ECG module are minimized.  The computer is also programmed to compare measured test information with predetermined expected values, and in the event of a discrepancy, to collect additional information from the patient to assist trained personnel at the central unit in interpreting the composite log.  The computer is also programmed to alert the central unit promptly in the event one or more measured parameters falls outside of a prescribed normal range.  The normal range for a given parameter is made to vary in accordance with the measured value of one or more other parameters in order to reduce the incidence of false alarms.

Title: Method for the preparation of copper arsenate
Inventor: JONES DAVID L
IPC: C01G28/02
Filed: 1988-09-02
Granted: 1992-07-07
Abstract: ABSTRACT         METHOD FOR THE PREPARATION OF COPPER ARSENATE            Copper arsenate, substantially free from impurities that form sludge in wood preservatives such as chromated copper arsenate, is prepared by adding a solution of soluble arsenate to copper sulfate solution, either or both solutions containing sludge-forming impurities, to form a copper and arsenic-containing solution without precipitating copper arsenate. The pH during the adding is controlled at a value in the range of 1.8 to 2.2 to precipitate impurities. Precipitated impurities are removed, and the copper and arsenic-containing solution is neutralized with a suitable alkaline substance to pH 3.5 to 5.0 to precipitate copper arsenate. Arsenate solution is derived from arsenic oxides, soluble arsenic salts and compounds and metallurgical materials capable of yielding water-soluble arsenate. Copper sulfate solution is derived from crystals and compounds and metallurgical materials cable of yielding copper sulfate. In a preferred embodiment, sodium arsenate is derived by aqueous caustic oxidative pressure leaching of flue dusts and copper sulfate is derived by aqueous acid oxidative pressure leaching of copper matte.

Abstract: APPARATUS FOR AND METHODS OF ADDRESSING          DATA STORAGE ELEMENTS          Abstract of the Disclosure An apparatus for and a method of addressing data storage elements (16) employs an ionizable gas to address the storage elements for storing data in and reading data out of them.  The storage elements are defined by the overlapping areas of multiple column electrodes (18) extending in a common direction on a first substrate (48) and multiple channels (20) extending in a common direction on a second substrate (54).  A layer of dielectric material (46) separates the first and the second substrates, which are positioned face-to-face and spaced-apart with the direction of the channels transverse to that of the column electrodes.  Each of the channels is filled with an ionizable gas and includes a reference potential electrode and a row electrode electrically isolated from each other.  The column electrodes receive data drive signals, and the row electrodes and reference potential electrodes receive data strobe signals.  The addressing apparatus is configured so that for each storage element the ionizable gas functions as an electrical switch that changes between a conducting or plasma state and a nonconducting or de-ionized state in response to an applied data strobe signal.  The ionizable gas functions to either store data in or read data out of the storage element.  If the storage element includes a layer (44) of material having electro-optic properties and receives incident image-carrying light, the ionizable gas functions to select and store image data across the layer and thereby provide a display system having gray scale luminance.

Title: Method and apparatus for determining the rotor resistance of a rotating-field machine
Inventor: SCHMIDT ROLF
IPC: H02P21/16
Filed: 1989-01-12
Granted: 1992-10-27
Abstract: ABSTRACT OF THE INVENTION         In order to determine the rotor resistance of a rotating field machine, a current is impressed in the stator via a field-oriented control, which current has a harmonic component above the nominal frequency of the machine.  From the current, the rotor position and a readjustable parameter value for the rotor resistance, a current model calculates a field-parallel EMF component EF1, the harmonic component EF1N of which is isolated.  In addition, a voltage model calculates from the current and the voltage, the EMF vector as the current component reference value EF1' and its harmonic component EF?.          A correction control CR1 readjusts the parameter rR of the rotor resistance until the difference of the two isolated harmonic EMF components disappears.  The test signal has practically no influence on the flux and the torque of the machine.  At the same time, the stator resistance rS and the stray inductance xSt can be determined.

Abstract: Abstract The application refers to a system for transferring audio and/or video information via an information carrier e.g. DAT, CD or CDV.  In the R-W sub code channel of the CD-signal textual information about the audio and/or video signal has been recorded.  This information is divided in packets.  Packets containing information of different categories are interleaved. After reading the information from disc the packets of a selected category are separated from information read.  This system of transferring additional information allows the use of an own packet category for each of a number of different languages, so that a user can select language with which he is familiar at most. Further, menu information, comprising coded menu text lines and command codes, are recorded in the R-W sub code channel for interactive control of the read-out of the audio and/or video information or the control of other connected devices.
