Abstract: Abstract of the Disclosure The invention relates to a high-voltage network.  The high-voltage network includes a transmitting substation and a receiving substation and an overhead power transmission line which connects busbars at the transmitting and receiving substations.  A source for melting icing is joined, during the ice melting, to at least one disconnected phase of the power transmission line at one end of the power transmission line.          An insulated conductor is joined,  during ice melting, to at least one disconnected phase at the other end of the overhead power transmission line.  The network may also include an additional overhead power transmission line leading away from the busbars of the receiving substation.  The additional line also includes an insulated conductor, and one end of the insulated conductor is grounded while the other end of the insulated conductor is joined, during ice melting, to at least one disconnected phase of the main overhead power transmission line.

Abstract: ABSTRACT OF THE DISCLOSURE      Conveyor gas is passed through a conveyor conduit to covey bulk material therethrough, while clean gas is passed through a by-pass conduit connected to the conveyor conduit at positions spaced along the length of the conduits.  The by-pass conduit can be divided into a plurality of sections by shut-off valves which close in response to n predetermined pressure difference between the two conduits, with a reduced pressure in the conveyor conduit due to a blockage of material therein.  Due to the pressure difference, clean gas is transferred from the by-pass to the conveyor conduit at a plurality of said connections between the two conduits, only in the respective section in which there is the pressure difference.

The tool consists of a mandrel sleeve having an inner tapered surface, a series of conical rollers mounted in a roller cage within the mandrel so the rollers bear against the tapered surface.  With the pipe inserted between the rollers and with relative rotational and axial movement between the pipe and the mandrel, the rollers will engage the surface of the pipe applying a swaging force to the pipe which is increases by the decreasing diameter caused by axial movement of the pipe and rollers along the tapered surface.

Abstract: ABSTRACT OF THE DISCLOSURE         An ultrasonic ranging system for a camera includes an ultrasonic transducer responsive to a keying pulse for transmitting a frequency modulated burst of ultrasonic energy toward a subject.  The leading half of the burst is a chirp whose frequency varies from a higher to a lower value; during the trailing half of the burst, the frequency remains substantially constant.  The system also includes a receiver for processing an echo signal produced by the transducer on receipt of an echo within a predetermined time interval following the burst, and producing a range signal with a characteristic linearly related to the distance of a subject being photographed from the camera.  A variable Q filter in the receiver filters echo signals produced by the transducer eliminates the need for a matched filter.  The filter Q has a relatively low value during the initial portion of said predetermined time interval causing the bandwidth of the filter to be wide enough to pass all the frequencies of the chirp returned from a subject relatively close to the camera.  During the remaining portion of the interval, the Q increases narrowing the filter bandwidth and optimizing it, with regard to the signal-to-noise ratio, for the constant frequency of the burst returned from a relatively remote subject.  This arrangement reduces sensitivity of the receiver to echo cancellation due to interference between waves reflected from a nearby subject without adversely affecting the signal-to-noise ratio for returns from remote subjects.  An accompanying change in filter admittance reduces angular sensitivity of the receiver to off-axis echoes.

Abstract: HIGH TEMPERATURE THERMAL STORAGE SYSTEM      UTILIZING SOLAR ENERGY UNITS                Abstract of the Disclosure A thermal storage system includes a solar collector.  A first fluid circulating through the col-lector is piped to a heat exchanger wherein heat in the first fluid is transferred to a second fluid circula-ting through a heat pump circuit.  The temperature of the second fluid is further elevated by the heat pump and is circulated through a second heat exchanger thereby transferring heat to a third fluid.  The third fluid is circulated through a third heat exchanger to elevate the temperature of a fourth fluid stored in a high pressure, high temperature storage tank.  The fourth fluid is em-ployed to elevate the temperature of a working fluid that may be used for consumption or heating.  Alternate embodi-ments of the fluid system include an accumulator tank wherein heat from the first fluid is transferred to fluid in the accumulator tank.  Heat from the fluid in the accu-mulator tank is transferred to the second circulating fluid or heat utilization means as required.  Automatic transfer to a fourth fluid heated by auxiliary means, and stored at high pressure and temperature is provided when the accumulator tank temperature drops below a pre-set valve.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus are disclosed for drying and pelletizing organic material such as animal waste, sewage and the like.  The organic material is dried in two stages using a high temperature, rotating primary drying drum, and a lower temperature secondary louvred drying drum.  The primary drum includes an inlet section and an outlet section.          The inlet section includes a plurality of transverse chain curtains for increased heat transfer to the organic material, for breaking up the organic material and for cleaning the sides of the drum.  The primary drum outlet section includes a plurality of vanes angularly attached to the inside of the drum to form an auger to retain the material in the drum until it is partially dried to a desired level.  The organic material is then transported to the secondary louvred dryer.  The louvred dryer includes an input section, an output section and a central pelletizing section formed by adjacent portions of the input and output sections. The louvred dryer input section is connected to a supply of heated air and the louvred dryer output section is connected to a supply of cooling air.  An adjustable baffle is located in the pelletizing section for use when it is desired to pelletize the organic material.  The baffle defines a con-tinuous cylindrical rolling surface which blocks the air flow through the louvres in the pelletizing  section and which rolls the organic material to form pellets.  The longitudinal location and the longitudinal length of the baffle may be adjusted for controlling the point where pelletizing begins and for controlling the size of the pellets.  Suitable air-pollution apparatus is provided to prevent atmospheric pollution.

Abstract: ABSTRACT OF THE DISCLOSURE An animal trap having two similar frames each having jaw forming sides and ends extending between the sides to support the jaws.  The ends have a central portion in which the frames are pivotally engaged through adjacent ends for rotation about a common axis between set and closed positions and outer portions on each side of the central portion extending to the jaws.  At least one actuator cap-able of rapidly and forcefully effecting the rotation is present.  The actuator has two arms spring biased at one end so that the other ends, which terminate in rings encircling adjacent ends of both frames on opposite sides of the axis would, if unobstructed, move apart to a distance substan-tially greater than the length of the frame ends.  There are trigger means for releasably maintaining the trap in set position.  The trigger means comprises a trigger lever pivotally connected to a first frame and extending, when the trap is in the set position, to engage releasably the second frame at first and second points, spaced from each other. The trigger has contact means extending, when the trap is in the set position, from the trigger lever across the trap. Movement of the contact means moves the lever from engage-ment of the first and second points and thus releases the trap from the set position.  The trap is particularly useful for trapping long legged animals.  The contact for the animal cannot be seen by the animal approaching the trap, indicating a clear pathway to the animal.
