Abstract: METHOD AND APPARATUS FOR MONITORING      METABOLISM IN BODY ORGANS     ABSTRACT    A spectrophotometric method and apparatus are directed to non-invasive, continuous, atraumatic, in vivo, in situ monitoring of metabolism in a body organ. In the described applications, measuring and reference wavelengths within the near infrared region, i.e., 700-1300 nm, are utilized for non-invasive, continuous, atraumatic, in situ, in vivo monitoring of oxidative metabolism by monitoring oxygen sufficiency in an internal organ, e.g., the brain or heart, of a human or animal body.  Advantage is taken of the critical characteristic of cellular enzyme cytochrome a, a3 within the optical path and within the radiated portion of the selected organ for absorbing the selected measuring wavelength and for light of this measuring wavelength, as well as at least one reference wavelength within the same defined infrared region and at a low, non-hazardous level of intensity to be detectable at the end of a relatively long transillumination or reflectance path, e.g., of several centimeters length, which may include substantial content of bone as well as soft tissue and skin.  Variations in metabolic and circulatory parameters during measuring are recognized and the selection of wavelengths, circuitry and method also provide techniques for compensating for changes in blood volume in the organ being monitored, for continuous monitoring of hemoglobin oxygenation and blood volume, for intermittent monitoring of blood flow rate,for skin blood flow effects and variations in the light source, i.e., laser diode, output.

Abstract: ABSTRACT OF THE DISCLOSURE Catalysts for use in promoting hetrogeneous chemical reactions in the gas phase, such as hydrogenation, cracking, dehydrogenation and Fischer-Tropsch reactions, are prepared by depositing a catalytically active metal such as nickel electrolytically onto an aluminum substrate in such a manner that the metal particles are deposited in micro-particulate form to enhance their catalytic activity.  The aluminum substrate is prepared by cleaning and anodizing it, so to deposit thereon an aluminum oxide surface film having micro porosity.  Then the substrate is immersed into an electrolysis bath of solution of salt of the metal to be deposited, and subjected to alternating current electrolysis to cause the required deposition.  Prior to use, the catalysts so prepared should be heated to remove absorbed gases from their porous surfaces.

Title: Process for thermal treatment, especially drying
Inventor: CURTIUS FRIEDRICH
IPC: C02F11/13
Filed: 1980-05-26
Granted: 1982-06-29
Abstract: ABSTRACT The invention relates to the thermal treatment of flowable material using heated contact surfaces in a fluidised bed. Known processes use a gas, often air, to fluidise the bed. This imposes limits on the tempera-tures that can be allowed to be reached as higher temperatures can cause the material to be treated to burn. It also often produces sterilization of the material. Further there is the problem of disposal of the gases generated in the treatment process. In an attempt to alleviate these problems, the present invention proposes a process generally of the abo-ve kind but in which the fluidising gas comprises gases generated in the bed itself. This is economical as it reduces the heat losses, environ-mentally desirable as it reduces the amount of gas discharge and more efficient as these gases are generally inert, thus enabling higher tempe-ratures to be generated in the bed without risk of the material burning, thus also facilitating sterilization of the material.

Abstract: IMPROVED METHOD AND APPARATUS FOR SECURING DATA TRANSMISSIONS                   ABSTRACT OF THE DISCLOSURE       A method and apparatus are provided for improving the security of data transmissions between stations and for controlling secured transactions from remote locations in a data-transfer system.  The method and apparatus obviate the need for transmitting user-identification information such as personal identification number (PIN) from station to station, e.g., from the station utilized by the user to enter his PIN and initiate a transaction, to the station that processes the transaction.  Data transfers between locations within the system may be remote-controlled using conventional data links, and this permits convenient changes of and additions to the files of stored codes for the system without compromising the security of data transfers or of identifying codes for authorized individuals.  An encoding center may be established which can be contacted by telephone and supplied with the PIN of a user and which can produce an encoding word that is received by the user via the telephone for his subsequent use in completing a telephone-oriented transaction.

Abstract: ABSTRACT:        A field effect transistor of which source and drain are realized partly as a semiconductor region in the semiconductor body, partly as a part of a deposited epitaxial layer, while the channel region underlies a recess in the substrate.  As a result of this construc-tion the channel length is independent of variations in the thickness of the epitaxial layer and the  stray capac-itances from source and drain to the substrate are small.      Moreover, a conductor pattern, separated from the epi-taxial layer by an insulating layer may extend to beyond the connection zones of source and drain, which involves a high packing density.  The epitaxial layer moreover comprises extra wiring tracks; this gives a large free-dom in design.
