Abstract: ABSTRACT The invention relates to metallic object detector comprising a coil system with a transmitter coil for generating an electromagnetic field and a receiver coil which is arranged in such a way that an electromotive force is induced in the coil when the coil is affected by the field generated by a metallic object and the field generated directly by the transmitter coil.  The invention relates particularly to the transmitter side and includes a feed-back circuit for keeping the amplitude of the electromagnetic field generated by the transmitter coil constant.  The transmitter side comprises, specifically, an oscillator which generates a sinusoidal signal for the transmitter coil and a variable attenuation/amplification circuit which controls the amplitude of the sinusoidal signal.  The attenuation/amplification circuit is controlled by a signal which is emitted by the coil system after the sinusoidal signal has been rectified and compared with a reference voltage.  In one embodiment it is the signal emitted by the receiver coil due to the directly induced electromotive force in the coil which is fed back but in a second embodiment it is a signal emitted by the transmitter coil which is fed back.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method and an apparatus for a direct airborne electromagnetic prospecting of hydrocarbon deposits wherein it is carried out a circling with an helicopter along a surveying network composed of identical closed rectangular profiles stacked one above the other at different altitudes.          Induction signals received during such a circling are compensated for a total signal measured at a starting point of the circling, and the so compensated induction signals which are representative of the amplitude and phase of three orthogonal electromagnetic field components Hx, Hy and Hz are measured and stored.  The electromagnetic field compo-nents vary with the flight altitude of the helicopter, with the used frequency, with the orientation of an induction transmitter loop and with the position of the helicopter, the used frequency being at least one frequency selected within the range of 0.1 - 10 Hz.  A multidimensional geo-physical information vector is formed from the induction signals and is processed into a discriminant function based on a pattern recognition theory and previous reference helicopter flight results.  Last of all, the resulting patterns are classified in accordance with the probability level of a hydrocarbon deposit occurrence.

Abstract: COMPOSITIONS FOR TREATING GLAUCOMA           Abstract of the Disclosure A method for the treatment of glaucoma or lowering intraocular pressure in a mammal, involving topically administering to the eye of such mammal a selectively metabolized beta-blocking compound of the formula   wherein R may be lower alkyl, lower hydroxyalkyl, lower alkynyl, aralkyl, or an ester-containing group and Ar may be substituted or unsubstituted aromatic; or a pharmaceutically acceptable salt thereof.  Because of a relatively long duration of action of such compounds in ocular fluids and a relatively short duration of action in the systemic circulation, such compounds are useful for the treatment of excessive intraocular pressure without substantial systemic effects.

Abstract: INDEXABLE COMPOSITE CUTTING INSERT HAVING      CORNER CUTTING EDGES                  ABSTRACT OF THE DISCLOSURE   An indexable composite cutting insert which is generally polygonal in plan view and includes spaced upper and lower surfaces, is composed of a core, such as a SiC-Si composite material, with the corners along one surface of the composite cutting insert being made of a superhard material of diamond or cubic boron nitride crystals bonded to the core.  The limited use of super-hard crystals in the critical areas of the cutting edges of the insert results in significant cost savings, both in manufacturing costs and costs of materials, as well as minimum warpage of the insert.  In addition, improved wear resistance of the cutting edges of the insert is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE           In a process for decontaminating contaminated metallic scrap, an oxygen bearing hot gas stream is passed into the inlet end of a container and is discharged from an exit end of the same container.  The decontaminated scrap is loaded in the container at the inlet end.  Concurrently the scrap is (a) moved from the inlet end to the exit end, (b) mixed and agitated within the interior of the container, and (c) during the mixing and agitation contacted with the hot gas stream moving through the interior of the container.  The contact of the scrap with the hot gas stream is under conditions essentially capable of inhibiting flaming.  By virtue of the contact with the hot gas stream, heat from the hot gas stream is transferred to the scrap, which lowers the temperature of the hot gas stream while raising the tempera-ture of the scrap.  This heat transfer takes the scrap to a first temperature phase wherein contaminants such as organics are volatilized and/or cracked into volatiles which become dispensed and diluted in the gas stream.  Further, water is converted into steam.  The volatiles including the stream are rapidly removed from the container by virtue of their disbursement into the gas stream.  Further transfer of heat to the scrap raises the scrap to a second temperature phase wherein contaminants which are not volatilable, but which are subject to oxidation below 1200°F., are oxidized by oxygen in the gas stream.  The scrap is maintained within the second temperature phase for a time sufficient to ensure complete oxidation and then the scrap is discharged from the container.

Abstract: ABSTRACT OF THE DISCLOSURE       A super-tough molded elastomeric chewable poly-urethane toy for an animal.  The toy may be shaped to simulate  a dog bone and to make swallowing difficult when being chewed.  It is also chemically inert in the animal's digestive system and is characterized by moderate hardness, resilient deformability, large tensile strength and resist-ance to shearing.  It is generally slightly heavier than water, but may be foamed or impregnated with air to float. The toy also makes use of a unique property of polyurethane whereby a surface-migrating flavoring pleasing to the animal is mixed with the polyurethane composition while the latter is in a liquid phase prior to being molded to the desired shape.  Thus as the flavoring is chewed off or other-wise dissipated from the exterior surface of the toy, the flavoring is continuously replenished.
