The collector has a casing having a discharge port at the center thereof for receiving the excavated material and a helical screw, incorporated within the casing, having two sets of spiral blades for gathering the excavated material toward a discharge port and expellers for expelling the material forcibly to the first conveyor through the opening according to the rotation of the screw.

Abstract: A fiber optics sensor (10) and method for attaining accurate measurement are provided. A polarization maintaining optic fiber (22) forms a linear optical path. An optical element (24) is used to convert linearly polarized light waves to circularly polarized light waves which propagate along the optical path and pass through a sensing medium (24). Because of external stresses and disturbances, the optical element (24) introduces light of the wrong state of polarization into the optical path. The result is a scale factor error in the measurement and an extra incoherent D.C. light detected at the detector (36). The presence and magnitude of the extra incoherent D.C. light is used to provide a normalizing factor to compensate for the scale factor error.

Abstract: The time-triggered communication control unit and method for the transmission of messages within a distributed real time computer architecture consist of a plurality of fault-tolerant units, in which the information to be transmitted consists of a control field (K), a data field (D) and a CRC (Cyclic Redundancy Check) field (CRC). The contents of the CRC field are calculated over the concatenation of the control field (K), the data field (D) and the local internal state of the transmitting communication control unit. The local internal state of such a communication control unit consists of a concatenation of the global time with a membership field. The membership field is composed of a sequence of bits, where each bit is assigned to a unique fault-tolerant unit. The value TRUE of a membership bit means that the assigned fault-tolerant unit is operating, the value FALSE means that it is faulty.

Abstract: Lignocellulose-containing materials are treated with lime (calcium hydroxide) and water at a relatively high temperature and for a certain period of time under certain conditions. The process variables were: lime loading which ranged from about 2 to about g Ca(OH).sub.2 /100 g dry material; water loading which ranged from about 6 to about 19 g water/g dry material; treatment temperature which varied from about 50.degree. C. to about 150.degree. C.; and treatment time which varied from about 1 to about 36 hours. The effects of treatment time and temperature were interdependent.A process for lime recovery is developed. The soluble Ca(OH).sub.2 was washed out of the pretreated material with water and converted to insoluble CaCO.sub.3, by reacting with CO.sub.2, and was thus separated. The CaCO.sub.3 can be heated to produce CaO and CO.sub.2. The CaO is hydrated to Ca(OH).sub.2 which can be reused as the lignocellulose treatment agent. Carbon dioxide is reused for lime recovery.

Abstract: Multi-phase RF ablation employing a two-dimensional or three-dimensional electrode array produces a multitude of currents paths on the surface of the ablation zone. This results in a uniform lesion with a size defined by the span of the electrode array. An orthogonal electrode catheter array suitable for cardiac ablation is used in conjunction with a two-phase RF power source to produce uniform square-shaped lesions of size 1.2 cm.sup.2. Lesions of larger size are created by successive adjacent placement of the square-shaped lesions. A temperature sensor at the electrode tip allows monitoring of ablation temperature and regulation of thereof to minimize the electrode tips from being fouled by coagulum.
