Abstract: The Toroid Sweep Engine with Reciprocating Jut generates power within a toroidal-shaped chamber whose walls are divided into two ring-like sections which are free to rotate relative to one another around the toroid axis. An obstacle juts from each of the wall sections into the chamber. Fresh air is pumped at high pressure and high temperature into a region of the chamber between the two obstacles, and fuel is then injected into and burned in this region. The products of combustion force the obstacles apart, turning a wall section, and when the obstacles eventually meet after circumnavigation of the toroid, one of them withdraws from the chamber allowing the obstacles to pass. More fresh air and fuel are introduced between the again separating obstacles following the rendezvous, while spent gases from the previous burning are swept and squeezed out an exhaust duct leading from that volume within the chamber which is compressed between the obstacles.

The fuel control system comprises load control signal generating means and idling control signal generating means for detecting the operating parameters of a gas turbine engine and generating a load control signal and an idling control signal each corresponding to the proper fuel feed quantity under load conditions and idling conditions, respectively, and an upper limit selection circuit for selecting greater one of the signals from the two means and generating a fuel control signal for commanding the proper fuel feed quantity.

Abstract: For improved thrust responsiveness and smooth transition of the various zones of an augmentor of an augmented jet engine powered aircraft, the time to prefill the fuel manifolds of the zones are calculated from preselected parameters so as to be on line upon light-off. The throttle lever signal is rate limited so that the preascertained manifold volume of each zone divided by the zone filling fuel flow produces a signal indicative of the time to open the normal fuel fill valve to prefill the manifold at the proper time and in the right sequence using a rate limited throttle lever signal.

Abstract: Apparatus for measuring and controlling the relative humidity of exhaust air from an industrial drier in which exhaust air is passed across a dry bulb and a wet bulb thermocouple from which a voltage is derived providing a measure of the relative humidity in the air in the sample. This voltage is used to control the amount of exhaust air from the drier to atmosphere. The wet bulb thermocouple is cyclically dipped in a bowl of water under the control of a timer system of the voltage to control the amount of exhaust air discharged until the wet bulb thermocouple is equilibrated with the exhaust air sampled after dipping.

Abstract: A ventilated enclosure is formed by an air duct, one end of which is closed ff by a partition pierced with ventilation apertures and the other end of which is closed off by a wall to which is attached at least two fans and which is provided with openings through which air drawn into the interior of the enclosure from its exterior is passed. Each fan is provided with a detection device for detecting inadequate ventilation. The detection device is positioned in the area which is swept by the stream of air which is produced by the associate fan when in operation and generates a signal when the output of air from this fan falls below a predetermined limiting value. Each detection device consists of a thermal detection element designed to emit a signal when its temperature becomes equal to a predetermined temperature threshold and an air non-return casing.

Abstract: The inlet air temperature and the exhaust gas temperature of a gas turbine power plant are monitored and are utilized as a determining characteristic in a power output stabilization control circuit. The control circuit is designed to change its response upon the attainment of a particular inlet air temperature threshold to conform to differing high and low temperature operating characteristics of the gas turbine power plant.

Abstract: An apparatus for monitoring whether the combustion system of a gas turbine is working properly includes an annular array of temperature sensors disposed in the gas turbine to monitor the temperature of the hot gas stream at a plurality of spaced positions and a temperature sensor disposed in the gas turbine to monitor the temperature of the compressor discharge flow, a digital computer, a circuit to input signals indicative of the sensed temperatures of a selected sensor to the digital computer, and a circuit for selecting the temperature sensor to be sampled. The digital computer is programmed to sequentially sample the hot gas stream sensors and to determine the median temperature thereof, compute allowable temperture limits as a function of the median temperature and the compressor discharge temperature, and to output a shutdown or alarm signal when a predetermined number of hot gas stream temperature sensors exceed the allowable limits in a predetermined pattern.

The system has a common sensor and a common variable chamber temperature setting unit. A capillary tube system connects the operating elements to the sensor and the temperature setting unit. An adjustable spring associated with either of the operating units biases the associated valve in the closing direction to provide an operationally dormant dead zone.

Abstract: Apparatus and method for starting a gas turbine engine is shown wherein the combustion chamber has a fixed geometry providing a high throughput velocity to prevent flashback during normal operation of the engine. Thus, there is provided a flame holding zone out of the main flow path through the chamber that exhausts into the chamber upstream of a catalytic reactor element to preheat the catalyst to a sufficiently high temperature for continuous auto-combustion therein prior to the rotor of the engine attaining running speed. After running speed the combustion in the flame holding zone is extinguished and the velocity of the fuel/air mixture in the main flow path through the chamber is sufficient to maintain the combustion within the catalytic element for the continuous running of the engine without any flashback.

Abstract: A rotary internal combustion engine is described and shown having two piston and cylinder assemblies rotating about a single axis. The pistons reciprocate in rotating cylinders having a four cycle internal combustion engine process to receive air and fuel, to compress the air and fuel, to combust the mixture and to exhaust the gases therefrom. The pistons move in a set relation to each other, being connected by a common rod. The center of rotation of the pistons is dynamic relative to the center of rotation of the cylinders and cylinder blocks. Intake and exhaust valves are positioned about the periphery of the rotor assembly, and have staggered opening and closing schedules in order that air and fuel may be admitted and gases scavenged in accordance with the four cycle internal combustion engine principle.

Abstract: Remote control, day-night, outside rearview mirror control apparatus. The control structure includes a plurality of interconnection cables linking an orthogonally pivotable, double sided vehicle mirror and multi-axial actuation, operator control mechanism. Mirror movement in the form of yaw about the vertical axis thereof is facilitated via swivel motion of a control bat resulting in axial movement of cables terminating outwardly of the reference axis of the mirror. Mirror movement about the horizontal axis thereof, including 180.degree. flipping and control pitch adjustment, is facilitated through a single cable, double action mechanical servo which is responsive to axial and rotational control bat movement. The servo may be positioned adjacent the mirror or control bat and utilizes a spring loaded cam biased within a rotable casing to independently differentiate mirror pitch adjustment signals from day-night flip signals in a fashion which permits 180.degree.

Abstract: A pushpull cable conduit is made by continuously moving a tubular mandrel through a crosshead extruding die, forming a tape of micro-porous polytetrafluoroethylene resin into cylindrical form covering the mandrel as it enters the extruding die, extruding an outer layer of fluid polymeric material over the cylindrical covering in the presence of heat, helically wrapping contiguous wires over said outer layer to form a wire layer, extruding an outer covering of thermoplastic material over the wire layer, and removing the tubular mandrel. The porosity of the polytetrafluoroethylene covering insures a good heat bond with the outer layer of fluid polymeric material and also provides a lubricant reservoir in its inner surface, thereby minimizing friction with the cable core and greatly reducing sound transmission.
