Abstract: A B S T R A C T          The invention relates to a method for converting metalcontaining waste material having substantial quantities of organic constiuents, such as plastics, rubber, paper and greases, to a product from which metal can readily be recovered. The waste material is introduced into a reactor vessel arranged for rotation about its longitudinal axis and provided with bottom and a common charge and discharge opening, whereafter the reactor vessel is rotated with its axis inclined to the horizontal plane at an angle of less than 90°. The reactor vessel is held during this rotation at a temperature which is sufficiently high to expel organic constituents in the form of a combustible gas far as long as such a gas is generated. The combustible gas is com-busted continuously at a location external of the reactor vessel, and the residual content of the reactor vessel is taken out in a molten and/or non-molten state. During at least a part of the expulsion process, air or gas containing free oxygen can be supplied to the reactor vessel through a lance in sub-stoichiometric amount.

Abstract: ABSTRACT OF THE DISCLOSURE     A deliquefying system including at lenst one drainage device having a wear surface and being connected to a source of suction open to the wear surface.  A wet web of material to be deliquefied is passed over the wear surface so that liquid is removed from the wet web of material by the drainage device.  A liquid deckle is at each exposed end of the drainage device in position to prevent air from entering the drainage device through the end zone and thereby restricting the flow of air to passage through the wet web into the drainage device.

Abstract: ABSTRACT:            "A method of cleaning humid air contaminated with vapour"        A method of cleaning humid air contaminated with vapour, such as ventilation air from a rolling mill or the like, comprises the steps of cooling the air in one or more stages to a temperature below the condensation temperature of the contaminating vapour in the air, and below the dew point of water. The condensate is collected in such a way that the condensed vapour is substantially separated from the condensed water. The condensed vapour may then be re-used. The water, which may still be contaminated with a small proportion of the condensed vapour, is returned to the air to re-humidify the air. In a preferred embodiment the cooling is conducted in two stages, the initial stage condensing substantially only the vapour, and the second stage condensing the water together with a relatively small propor-tion of the vapour still remaining in the air. The condensate may be separated into two phases in a separation tank.

Abstract: ABSTRACT OF THE DISCLOSURE           A pressure medium actuated servomotor system is disclosed which includes a piston sliding in a cylinder.         The piston limits within the cylinder two chambers, each being connected by a first individual line to a pressurized medium source.  A second individual line for each of the chambers connects the chamber to a pressurized medium sink.         A control valve is disposed in one of the two connecting lines of each chamber.  A restructure is arranged in the second connecting line of each piston chamber.  At least a first one of the two control valves is connected to an external control line.  According to the invention, the second control valve is operable by pressurized medium and communicates over an internal control line with the piston chamber to which the control valve communicating with the external control line is connected.  The advantage is in that the servomotor can be actuated by utilizing only a single line which does not have to be loaded more heavily than each of the two single lines typical for prior art arrangements.

Abstract: No-Feedback Steering System for Marine Drives Abstract of the Disclosure A steering system for a steerable marine drive has a fluid filled cylinder with the housing connected to the boat and the piston connected to the steering arm of the marine drive.  The piston contains valves operated by the control cable con-nected to the steering wheel of the boat.  When the valves are closed, the piston, and hence the marine drive, is locked in position.  Propeller torque or other forces imposed on the marine drive are trans-ferred to the boat rather than to the control cable and the steering wheel.  To steer the marine drive, the control cable initially opens the valves in the piston, unlocking the marine drive.  Thereafter it moves the marine drive to the desired position.  A lost motion mechanism, including that used in a vane steering system, may be utilized for this purpose. Alternately, the piston may lock the lost motion mechanism rather than the marine drive, to prevent the transmission of forces to the steering wheel.

Abstract: ENDOTRACHEAL CARDIAC MONITOR     ABSTRACT OF THE DISCLOSURE A flexible endotracheal tube includes at its distal end an inflatable cuff adapted to monitor acoustically the cardiac pulse. The inflatable cuff, when inflated after insertion of the endotracheal tube into the trachea of the patient, contacts and conforms to the inner wall of the trachea to provide an airtight seal, thereby permitting the administration of anesthetic gases, as well as control and monitoring of the respiratory function through the respiratory passage within the endotracheal tube. The cardiac pulse is acoustically transmitted from the interior tracheal wall through the inflatable cuff and into the associated inflation conduits, one of which terminates in a monitor connector suitable for monitoring the cardiac pulse. A transducer connector housing an electromechanical transducer mates with the monitor connector and produces an electrical signal which is suitably processed and subsequently used to drive a visual display, a chart recorder, and to provide an audio output.

Abstract: FIBER OPTIC ROTATION SENSOR UTILIZING        HIGH BIREFRINGENCE FIBER         Abstract A fiber optic rotation sensor comprises a fiber optic interferometer  loop  formed  from  a  highly  birefringent optical  fiber,  and  a short coherence  length source  for introducing light into the interferometer loop to provide a pair of waves which counter-propogate therethrough.   A detector  is  included  to  detect  the  phase  difference between the waves after they have traversed the loop to provide  an  indication  of  the  loop  rotation  rate,  in accordance  with  the  Sagnac  effect.    Phase  errors  are reduced by selecting the coherence length of the source and the birefringence of the fiber, so that the loop is comprised of plural  fiber coherence  lengths.   The  term "fiber  coherence  length"  should  be  distinguished  from source coherence length.   Fiber coherence length is the length  of  fiber  required  for  the optical  path  length difference between the two polarization modes of a single mode  fiber  to  equal  one  coherence  length of  the light source.
