Abstract: GATED LIGHTNING DETECTION SYSTEM                 ABSTRACT OF THE DISCLOSURE           A lightning detection system utilizes a gated magnetic direction finder for determining the range and direction of lightning discharges to ground.  The magnetic direction finder is controlled by an electric field detector that includes logic circuitry for analyzing the waveforms of the detected electric field to determine whether the discharge is a ground stroke or other type of discharge, or background noise.  The magnetic direction finder is gated by the electric field control logic circuitry so that a direction measurement may be made for a few microseconds after it has been determined from the electric field waveform analysis that a ground stroke has occurred.  Different criteria are used for determining whether or not a stroke is a ground stroke depending on whether the stroke being anaylzed is the first stroke in a flash or a subsequent stroke.

Abstract: AN IMPROVED SLIDING DOOR UNIT     ABSTRACT OF THE DISCLOSURE      A sliding door unit having a stationary and a movable door panel has an improved sill which underlies and supports the door panels.  The sill includes sill surfaces of different elevations for imposing a gravitational potential on any water seeking to infiltrate between the door panels.  In addition, the sill includes a drain tank which operatively communicates with the highest sill surface for draining any water reaching that sill surface to an exterior side of the sill.  The sill also includes an improved support member for supporting an outwardly extending threshold of the sill.          Furthermore, the sill includes a guide system for guiding the stationary door panel into place during manufacture of the door unit.  The improved sill is advantageous in preventing water from entering the meeting stiles of the door panels because of the change of elevation between the sill surfaces.

Title: Arrangement for cooling the cutter teeth of the cutting tool of a rock-cutting machine and for cooling the breast
Inventor: ZITZ ALFRED
IPC: E21C35/187
Filed: 1979-08-01
Granted: 1982-06-29
Abstract: Abstract This invention relates to an arrangement for cooling the cutter teeth of a cutting tool preferably a rotary cutter head, of a rock-gutting machine, which cutter teeth are only temporarily in engagement with the rock to be cut, and for cooling the breast, by means of nozzles which are mounted on the cutting tool and associated with respective cutter teeth and are supplied with water without an admixture of air. In order to save water, a discharge of water from a nozzle is to be restricted to the time in which the associated cutter tooth engages the breast. For this purpose the cutter teeth are axially slidably mounted in tooth holders and are resiliently biased substantially in the direction of the cutting pressure. As a cutter tooth is displaced under the action of the cutting pressure, a valve is opened which is upstream of the nozzle that is associated with the cutter tooth concerned. As a result, water is discharged from that nozzle as long as the associated cutter tooth is subjected to the cutting pressure.

Abstract: ABSTRACT OF THE DISCLOSURE:          A method for preventing damage to the strand guide elements of strand guide arrangements or roller aprons of a continuous casting installation for metal, especially steel, wherein it is possible to withdraw a strand which is immobile in the strand guide arrangement or roller apron, by means of a powerful withdrawal unit, without the risk of damaging ele-ments of the strand guide arrangement.  At pre-selected loca-tions of the strand guide arrangement there are determined the withdrawal forces effective at such locations and acting upon the elements of the strand guide arrangement.  Upon exceeding maximum permissible values the strand withdrawal operation is interrupted.

Abstract: A LATERALLY MOBILE IRRIGATION SYSTEM   Abstract of the Disclosure An overhead irrigation system and a method of control-ling it whereby a main irrigation pipe, supported on towers, is moved laterally across a field.  The towers at the extremities of the pipe are independently driven while the remaining towers move in response to misalignment between pipe segments caused by the motion of the outside towers.  Proper overall direction of the system is maintained by a path sensor which detects devia-tion from the designated path and corrects it by slowing down the tower at the end toward which the correction is required, thereby causing the entire unit to pivot about a point on or beyond and in line with the end of the unit.  Two-way misalign-ment sensors are capable of propagating a path correction signal along the entire length of the unit and in either direction.          An engine, generator and pump are mounted in a sling support hung from the pipe.

Abstract: Can. C-1722 CIP (ER/MRD) OUTDOOR EPOXY SHELL BUSHING            ABSTRACT OF THE DISCLOSURE           An electrical insulating bushing for outdoor use has a shell cast of a thermosetting resin, such as epoxy or the like, having a cylindrical conductive mesh shield embedded in an intermediate portion thereof and having means for connecting the shield to the grounded housing of an electrical apparatus.  An electrical conductor extends axially through a center bore of the bushing with an annular air gap formed between the exterior surface of the conductor and the interior surface of the bushing.  The embedded ground shield eliminates the need for a conductive ground coating on the exterior surface of the bushing.  The differing dielectric constants of the epoxy shell and air gap provide a field grading influence to reduce the maximum voltage gradient adjacent to the embedded ground screen, thus raising the corona inception voltage level of the bushing.  A thin insulation sheath is disposed around the full length of the electrical conductor in one embodiment of the invention.  The novel bushing of the invention is also disclosed for use in connection with switchgear with circuit breaker drawout capability where a novel bushing combination is used in which the circuit breaker bushing has the con-struction of the present invention.
