Abstract: ABSTRACT A spectrometer which comprises a light source for exciting a sample to be analyzed, and a monochromator whose intensity values, as detected at the output gap, are subjected to further processing in a computer, in conjunction with the associated wavelength values, for the purposes of achieving a large measuring range and a high degree of measuring accuracy, is provided with two secondary electron multipliers and a beam splitter which supplies the second secondary electron multiplier with only a small fraction of the radiation issuing from the monochromator.  An electronic switch transmits to the computer, by way of an A-D converter, the output of that secondary electron multiplier whose output signal is within the analysable range of levels.  The computer causes the monochromator to pass through the measuring range a plurality of times, and individually stores the measurement values which are then processed to form mean values.

Abstract: ABSTRACT OF` THE DISCLOSURE                     Methods of Assay An electrochemical specific-binding assay of a ligand wherein one of the components is redox-modified by having incorporated into its molecular structure a redox centre, and which includes the step of determining the extent to which an electro-chemical characteristic of the components is perturbed by complex formation and/or by controlled external influences.     Redox centres are molecules, atoms, groups, ions, radicals etc capable of undergoing reduction and oxidation.  A preferred example is ferrocene or its derivatives.     The electrochemical apparatus will typically contain a working electrode, which is preferably solid.  Components may advantageously be immobilised onto such a solid working electrode.     When controlled external influences are employed, these may comprise displacement of non-immobilised electroactive components relative to the working electrode.     The method is particularly applicable to the assay of antigens, haptens and antibodies.     The use of redox centres avoids radioactive labels and provides a simple, rapid, sensitive and specific assay method.

Abstract: ABSTRACT   Method and arrangement for signal transmission in ultrasonic echo sounding systems An ultrasonic echo sounding apparatus disposed at a measuring location transmits ultrasonic pulses in successive transmission periods. The echo pulses received after re-flection at a target are converted to electrical envelope signals which  represent the envelope curves of the echo pulses. The envelope signals are transmitted via a connecting line to an evaluation apparatus disposed at an evaluation station remote from the measuring location. In the evaluation apparatus the envelope signals are evaluated for determining the target distance from the travel time of the ultrasonic pulses. The transmission of envelope signals results in the advantage that the information contained in the pulse shape of the echo pulses is available in the evaluation station, although it is not necessary to transmit signals having the high frequency of the ultrasonic pulses via the connecting line. Preferably, the envelope signals are transmitted in a first section of each transmission period, and low-frequency signals which are generated at the measuring location and are characteristic of parameters necessary for the evaluation of the envelope signals are transmitted in a second section of each transmission period. It is also possible to transmit control signals from the evaluation station to the measuring location during the second section of every transmission period.

Abstract: SYNCHRONIZATION SYSTEM FOR USE IN DIRECT SEQUENCE SPREAD SPECTRUM SIGNAL RECEIVER                               Abstract A plurality of transmitters synchronized to a common clock each  transmit  a  data  signal  spread  by  a  common  bipolar pseudo-random  code  having  a  different  assigned  code  sequence shift.  A receiver, synchronized to the clock, discriminates the signals  transmitted by a predetermined transmitter from signals transmitted by the others by generating a first pseudo-random code that is a replica of the common bipolar pseudo-random code and has a code sequence shift corresponding to that of the predetermined transmitter,  and a second bipolar pseudo-random code that is a replica  of  the  common  bipolar  pseudo-random  code  and  has  an unassigned code sequence shift.  The difference between the first and  second  bipolar  pseudo-random  code  sequences,  which  is  a trinary  code  sequence,  is  cross-correlated  with  the  incoming signals.  The cross-correlation despreads only the signal having the predetermined code sequence shift.  Each receiver includes a number  of  correlation  detectors  offset  from  each  other  by  a fraction  of  a  code  chip,  together  with  decision circuitry to identify cross-correlation peaks.  The cross-correlation output of a   primary   correlation   detector   generates   in-phase   and quadrature-phase  correlation  signals,  with  the  quadrature-phase signal being  at  a minimum when  the receiver and predetermined transmitter are perfectly synchronized with each other.  The ratio of  the  in-phase  and quadrature-phase  signals  are processed  to identify the presence of a data signal within a background of noise and to improve synchronization lock between the receiver and predetermined transmitter.

Abstract: Abstract:    A method of recovering hydrocarbon from an argillaceous subterranean rock formation involving the flooding of the formation with an aqueous fluid to displace the hydrocarbon from the formation.  The method involves first subjecting the formation to an acid stimu-lation treatment by injecting a strongly acidic solution to dissolve acid soluble pore clogging materials, although this first step can be omitted, if desired.  The formation is then treated with a solution containing an acid, a sur-factant and a clay stabilizing agent.  The concentration of the treatment solution is initially quite high but is gradually reduced until a certain threshold concentration is reached, after which a treatment solution having this threshold concentration is continuously injected into the formation to displace the hydrocarbon.  The ingredients of the treatment solution exhibit a synergistic effect in maintaining a desirable rock permeability and a favourable mobility ratio between the treatment solution and the displaced hydrocarbons.

Abstract: ABSTRACT     Implant Tissue A collagenous fibrous tissue preparation of human or animal origin is described which is suitable for homo- or hetero transplantation either as a temporary dressing or as a permanent implant.  The fibrous tissue preparation is preferably in sheet form and is prepared by a process which results in the fibrous tissue being substantially free of non-fibrous tissue proteins, glycoproteins, cellular elements, lipids and lipid residues.  This process involves treatment of the fibrous tissue with a diisocyanate which unlike earlier processes using, for example, dialde-hyde treatment agents, provides a fibrous tissue preparation which is non-cytotoxic and is stable to endogenous proteolytic enzymes.  The preparation and use of the fibrous tissue is also described.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a gas-fired cooktop for a range which provides high thermal efficiency and low emissions of air pollutants, particularly low levels of NOx.  The cooktop includes a perforated tile burner which radiates infrared energy upward at a high flux rate to rapidly quench burner gas temperatures and inhibit the formation of NOx.  A perforated glass-ceramic jet plate positioned between the burner and a cooking vessel transmits most of the radiant infrared energy from the burner to the vessel and also forms jets of combustion products which are directed against the bottom of the vessel for convective heating.  Thermal efficiencies of up to about 70 percent and NOx emissions as low as about 15 parts per million are achieved by the cooktop.

Abstract: "METHOD FOR CONTROLLING WATER CONING IN OIL WELLS" In a reservoir having an oil zone underlain by an aquifer, injection and production wells are completed by perforating them in the oil zone, well above the oil/water interface. A non-condensable gas is then injected at the injection well while the production well is simultaneously produced. In due course, the gas establishes communication with the production well along the oil/water interface. A layer having a relatively high gas saturation is produced along said interface. Injection of gas is continued at a rate higher than gas is being produced at the production well. Primary production of the producing well is continued in conjunction with the gas injection. It is found that water coning at the production well is suppressed by the gas "blanket".
