Abstract: A B S T R A C T            The invention offers a new kind of retorting extractor which consists of the retorting tube which is installed in the furnace and it is heated by means of the burner. The tar-sand, or any other material containing the bitumen is loaded through the loading chute, situated on one end of the retorting tube, and the material is pushed through the whole length of the retorting tube, by the drag chain which moves inside the retorting tube. The process of the extraction ends at the other end of the retorting tube, where the material (sand) free from the bitumen is unloaded into the drive chamber and it is evacuated out of the extractor though the unloading chute, which is located at the bottom of the drive   chamber. The bitumen extracted from the solid material, flows through the manifold, welded to the top of the retorting tube, out of the extractor. The drag chain is driven by the drive sprocket, or by the drive system, consisting of the drive chain and two secondary sprokets, which are located in the drive chamber. The drive chain returns from the drive chamber through the return tube into the return chamber, where the idle sprocket re-directs the drag chain back into the retorting tube. The retorting extractor is practically air-tight: the retorting tube and the return tube are welded, or bolted to drive chamber, and to the return chamber, and the loading chute is also welded, or bolted to the retorting tube. Both loading and unloading chutes are equiped each with two gates, and during loading, or unloading, before one of the gates opens, the other closes.

Abstract: ABSTRACT OF THE DISCLOSURE An optical fiber communication system for transmitting information-bearing optical signals over an optical fiber transmission line includes a signal genera-tor coupled to the transmission line for introducing information-bearing optical signals thereonto, preferably as wavelength modulated signals, and one or more optical amplifiers for periodically, collectively amplifying the transmitted signals to overcome the effects of attenua-tion.  Wavelength modulation is achieved by altering the resonant characteristics of an optical resonator, opti-cally coupled to a gain medium so as to provide an output that varies between a first and second wavelength.  The optical amplification is achieved by injecting, prefer-ably via lateral optical fiber couplings, pumping beams into the optical fiber so as to effect an increase in the amplitude of the information-bearing signals by stimu-lated Raman scattering.

Abstract: Abstract of the Disclosure Hour Meter Apparatus and Method Electronic hourmeter devices having non-volatile memories are useful, for example, in industrial vehicles.  Advantageously, such non-volatile memories should be free from a need for battery back-up systems and should minimize the number of changes of the internal memory registers.  The subject electronic hourmeter apparatus includes both a dynamic memory device and a non-volatile memory device.  Data is maintained in each of the memory devices and memory bit changes are minimized by utilizing a gray coded binary representation of a portion of the data and by systematically altering the addressed memory location of a portion of the data in response to one of the stored data values.  Data storage occurs both periodically and in response to disconnection of the vehicle battery.  Thus, the disclosed electronic hourmeter apparatus 10 advantageously maintains the integrity of the stored data, minimizes the number of bit changes that occur in the non-volatile memory device, and avoids the need for a battery back-up.
