Abstract: METHOD AND APPARATUS FOR GAMMA RAY WELL LOGGING     ABSTRACT          Gamma rays from a subsurface earth formation are detected, and measurement of their respective energy levels transmitted to the surface where the resultant spectral data is stored in a plurality of narrow energy windows.  Functional relationships relating photoelectric cross-section, density, and soft-to-hard ratio are developed from a formation model.  These relationships are utilized with the stored spectral data in a perturbative process whereby effect of photoelectric cross-section on density is reduced and improved accuracy in density determination effected. Additionally, density is factored into photoelectric cross-section determination, compensating for effects of density on the soft-to hard ratio.  Availability of the entire spectrum permits improved resolution of the windows, monitor peaks, and detectors t and permits compensation for detector resolution in the observed spectrum.  In one embodiment, the energy range over which the long space count rate is derived for determination of density is varied as a function of logging conditions.

Abstract: ABSTRACT OF THE DISCLOSURE           An electronic article surveillance system for microwave frequencies (500 MHz and higher) has low profile (i.e., shallow) transmitter antenna arrays and a low profile receiver antenna array, each array comprising a pair of thin metal patches, spaced apart in the normal direction of travel through a surveillance zone, and a thin metal ground plane behind the patches.  The patches and ground plane are in spaced parallel relationship.  Each metal patch and the adjacent portion of the ground plane together form a cavity resonator which resonates at a desired transmitter or return signal frequency and thereby form a signal radiating or receiving structure.  The patch size, patch to ground plane spacing, and spacing between patches are determined by the desired resonant frequency.

Abstract: ABSTRACT      Disclosed is a method and apparatus for forming pat-terns in a thick film circuit or the like to be used when forming elements such as conductors and resistors on a thick film circuit board.  The pattern forming apparatus comprises a writing head for storing paste to form patterns, and the writing head lowers and approaches an arbitrary point in close proximity to the board of a thick film circuit and, while in the same state, moves laterally to another arbitrary point along the surface of the board, and then ascends to be separated from the board.  The paste in the writing head is pressurized to be forced out of the head before the writing head begins to move laterally such that the paste is immediately applied on the board when the writing head begins to move laterally.  This pressurization of the paste is stopped before the writing head finishes its lateral movement, so that the extrusion of the paste may be stopped the moment the writing head finishes the lateral movement.  As a result, blurring or blotting at the begin-ning and ending part of the pattern writing may be prevent-ed, so that patterns may be formed at high speed and with high precision.

Abstract: Abstract of the Disclosure This invention pertains to a water-insolubi-lized resin of a polymer of at least one monomer selected from N-alkyl- or N-alkylene-substituted acrylamides or methacrylamides represented by the following general formula (I);                  (I) wherein R1 and R2 mean individually a hydrogen atom or methyl group and R3 denotes a methyl, ethyl or propyl group, with the proviso that R3 is an ethyl or propyl group when R2 stands for a hydrogen atom, and that R3 is a methyl or ethyl group when R2 stands for a methyl group, or wherein R2 and R3 form        or         in combination; or a copolymer of at least one monomer selected from the acrylamides or methacrylamides and another copolymerizable monomer.          The resin has water-absorbing capacity which varies in degree depending on temperature and, when heated, undergoes shrinkage even in the presence of a large excess of water to release once-absorbed water.          Because of this property, it may be used as a water-separating agent to remove water from a water-containing system.  Since the resin can exhibit a sort of molecular sieve action, it can selectively control the concentration of a macromolecular material without affecting the concentration of a low molecular weight compound such as a buffer agent.  The resin is useful particularly in concentrating an aqueous solution or emulsion containing a material susceptible to thermal denaturation, such as an edible substance, amino acid, protein, polysaccharide  or, enzyme which is difficult to concentrate by the evaporation technique, and also in controlling the concentration of an aqueous solution while adjusting the degree of water-absorbing capacity of the resin by varying its temperature.

Abstract: Abstract of the Disclosure In a method of culturing a plant with a dwarf habit, the plant to be grown is placed in a plant pot of a porous material as for example fired clay. The plant pot is placed within an outer jacket vessel so as preferably to leave a space between the two, such space being filled with a nutrient solution. The-?re are slits running from the interior of the pot radially outwards and/or axially downwards in the form of blind channels within the thickness of the pot wall. The roots of the plant grow into the channels and become trapped therein so that they do not develop any further but only put out fine root hairs. The retardation of the growth of the roots of the plant causes the plant to exhibit a permanently dwarfed habit.
