Abstract: ABSTRACT:    Infrared radiation source arrangement, in particular for use in infrared spectral analysis.  To an electrically insulating substrate (2) there is applied one and preferably at least two separate electrically conductive films (2a, 2b) adapted to be heated by ap-plication of a time dependent electric current thereto. Two or more films may form a radiation group (array) in which each film (2a, 2b) is adapted to be energized se-parately with electric current from an electric drive circuit (1) for applying a time dependent, preferably pulse shaped electric current to the film or films, so that infrared radiation pulses are emitted.  The electric current is time controlled in order that the radiation pulses from the respective films may be dis-tinguished from each other in a detector (6).  The thickness of the substrate and the thermal conductivity, specific heat and density of the substrate material are so chosen that the thermal time constant is adapted to the pulse frequency range of the drive circuit.

Abstract: CONTROLLED INERTING OF CHAMBER ATMOSPHERES    ABSTRACT OF THE DISCLOSURE A chamber such as a curing oven or drier is inerted during the curing of solvent borne resin coatings with the solvent vapor formed wherein being withdrawn together with inert gas at a substantially constant flow rate.  The withdrawn gas stream is supplied to a condensation unit to enable re-covery of solvent and the noncondensed gas discharged from the condensation unit is returned to the oven at a flow rate which may be varied so as to maintain a material balance with respect to the oven atmosphere.  Appropriate adjustments are made in response to changes occurring in the oven solvent vapor and/or oxygen concentration without disturbing the material balance mentioned above while the oven atmosphere is withdrawn it a substantially constant flow rate.  A plurality of ovens may be connected to a single condensation unit and upon detecting undesired conditions such as excessive oxygen levels in one oven, the same may be separately isolated from the condensation unit.                   BACKGROUND OF THE INVENTION The present invention relates to methods and apparatus for recovering solvent vapor from an oven or the like and more particularly to such methods and apparatus wherein a material balance is maintained with respect to the oven atmosphere.         Prior art techniques for recovering solvent vapor from curing ovens during the curing of solvent borne resin coatings typically include the withdrawal of oven atmosphere and the condensation of solvent vapor therefrom.

Abstract: DUAL MODE CODING     Abstract A dual mode encoding/decoding technique for use in digital systems wherein transmitted digital words are limited, on average, to an allotted number of bits.  The transmitted digital words are coded into first and second modes.  The first coding mode utilizes predictive diferential coding to provide a precision which can be greater than that obtainable by coding information solely with the allotted number of bits, while the second mode assures at least a minimum precision for the allotted number of bits.  The first coding mode is transmitted as long as a preselected precision is provided.  If not, the second coding mode is transmitted.  In the disclosed embodiment, the dual mode encoding/decoding technique is applied to the transmission of color video signals.

Abstract: A SYSTEM AND METHOD OF SEISMIC EXPLORATION            Abstract A seismic exploration system includes a gun shot control unit which compensates for the inherent delay between the shot command signal and the actual occurrence of the seismic pulse.  A digital clock 17 is synchronized with remotely located detectors for receiving the seismic pulses.  Timing pulses occurring at a time preceding the timing pulse upon which the occurrence of a seismic pulse is desired are produced by the clock 17.  These timing pulses start a digital counter 20 at a time preceding the desired time of occurrence of the seismic pulse.  The counter 20 is adjustable so that the delay which interposes between the timing and the actual occurrence of the seismic pulse can be minimized.
