Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus is disclosed which is adapted to conduct water from a source of water to a water consumer which is moveable relative to said source.  More particularly, watering apparatus is disclosed suited for watering large areas of ground.  Developments within the farming industry have resulted in increased requirements for the artificial watering of agricultural ground and a number of proposals have been submitted as to how relatively large surfaces of ground can be watered artificially using water sprays.  One such proposal suggests the use of a large number of spray devices mounted on a network of pipes, which network may be permanently in place or only temporarily in place.  Other proposals incorporate tractor-driven or tractor-carried pipes or hoses provided with water sprays.  Self-propelling apparatus have also been proposed, in which the water pipes are carried on a plurality of sequentially arranged wheels which are arranged to move parallel to a mains water-pipe or circularly around a water hydrant which may be permanent fixture or which may be moveably arranged.  All of the previously proposed systems have serious drawbacks.  The present invention is based on the concept of using two substantially identical, extendible and collapsible pipe-systems arranged to conduct water from a water source, for example a water mains or a water hydrant, to a water-consumer, for example one or more water sprays.  Each system of pipes is constructed of a number of substantially rigid pipes and a plurality of pipe-coupling devices which pivotally connect the pipes at the ends thereof in a manner to permit water to flow from pipe to pipe through the coupling devices.  The system of pipes is held together by holding means and is carried above the surface of the ground by supporting means.  The use of two pipe-systems enables substantially the same flexibility to be obtained as that obtained with hoses, whilst at the same time eliminating a number of the disadvantages encountered with hoses.  By connecting one end of respective pipe-systems to a water hydrant and the other ends of said system to a water spray, and by extending and collapsing the pipe-systems, the water spray can be moved reciprocatingly over a surface to be watered.

Abstract: SURGICAL INSTRUMENT FOR OPERATION OF ANTERIOR FENESTRATED SPONDYLODESIS IN VERTEBRAL          OSTEOCHONDROSIS            Abstract of the Disclosure A surgical instrument for the surgical operation of anterior fenestrated spondylodesis comprising an elongated hollow body with a handle at one end, and a detachable hollow cylindrical cutter with a cutting edge, at the other. Incorpo-rated within the body is a shaft with a knife on the end situa-ted within the cavity of the cutter.  The instrument has a de-vice for locking the shaft in the body in a position whereat the blades and cutting edge of the knife and the cutter lie in the same plane. The cutter is intended for excising two transplants in the shape of cylindrical segments from two adja-cent vertebrae, and the knife, for undercutting them, once they are formed by the cutter. Also situated in the cutter's cavity is a limit flange secured on the shaft, which comes in contact with the surface of the vertebral bodies and restricts the depth to which the knife descends into the intervertebral slit and, together with a stop on the rear end of the body interact-ing with the end of the shaft, ensures the right depth of the cutter's penetration into the adjacent vertebral bodies.    The instrument is reliable, does not endanger, during surgery, nearby large vessels and nerve formations, and pre-cludes the penetration of the knife into the vertebral canal. The instrument permits the operation to be performed on any region of the spinal column.

Abstract: ABSTRACT OF THE DISCLOSURE        The porous material adapted for making a tool-electrode therefrom features a porosity up to 15 - 25 per cent of its volume, a pore size within 10 to 40 microns and ?? oxygen con-tent up to 0.1 wt.%.  The method proposed for producing such a material resides in hot compression moulding of a powdery elec-trode material.  The powdery material is first heated in a com-pression mould to a temperature equalling 0.3 to 0.5 that of the melting temperature while pumping a gaseous reducing agent therethrough at a pressure of 1.2 - 1.8 atm, whereupon the powdery material is held for some lapse of time at that temper-ature, while continuing to feed said reducing gas in a quantity exceeding the stoichiometric one.  Next, the powdery material is heated to a temperature equal to 0.6 to 0.9 that of the melt-ing temperature, and a pressure is applied thereto to obtain the required porosity of the material being prepared.

Abstract: TITLE          METHOD AND APPARATUS FOR WRAPPING OBJECTS WITH A SEALABLE WRAP            ABSTRACT OF THE DISCLOSURE       A parallelogram linkage controls the speed of a sealing and cutting bar while in engagement with a poly-ethylene wrap while the wrap is being sealed around an object moving along a conveyor.  The linkage assures synchronism between the speeds of the sealing and cutting bar and a re-silient roller between which the wrap is pressed during sealing and cutting.  Pressure on the sealing and cutting bar is controlled by an adjustable but controllable air pressure link.  Sealable wrap is uniquely stored on the top and bottom sides of the conveyor such that it may be freely released when the object engages a web formed by the initial sealing of the two wraps together at a wrapping station.  Once the wraps have been cut and sealed to form a new web at the rear of the pre-viously wrapped object, the web is drawn back to position it for engagement by the next object in the path.  Also disclosed is the method of accumulating lightweight polyethylene-type films so that they may be easily pulled from the storage po-sition for wrapping around an object moving along a path.

Abstract: ABSTRACT OF THE DISCLOSURE            Method and apparatus for continuously detecting cracks in aircraft blades while in flight.  A hollow blade is sealed with a pressure differential, either above or below atmospheric. A reduction in the pressure differential such as results from cracks, is detected by a pressure sensor having a member which moves between a high pressure differential position and a low pressure differential position.  A radiation source, typically a beta source, is carried on the member and moves from a shielded position to an unshielded position when the pressure differential drops.  A radiation detector is mounted on a fixed portion of the aircraft ant detects radiation from the source when the member moves to the unshielded  position.  The detector output may be used to operate a go-no go indicator providing a warning signal when the pressure differential falls below a predetermined value, or to operate an analog indicator providing an output varying as a function of the pressure differential.
