Abstract: Abstract of the Disclosure A fire-protection sprinkler head with an improved response characteristic is disclosed.  A fusible link is provided with a fin  having multiple face portions oriented to direct air currents from any of a plurality of orthogonal directions over the fusible region of the link.  An embodiment with multiple fins provides an aggregate set of face portions that direct over the fusible region air currents that have X, Y, and Z orthogonal components in both positive and negative senses.  Air currents can be directed both by deflecting effects and air foil effects.  Preferably the face portions are facets formed integrally with sheet metal body members that form the link.  In the preferred embodiment the link and all fins are formed of a pair of similar stampings from sheet metal.

Abstract: TITLE            UTILITY DISTRIBUTION SYSTEM FOR FLOATING PIERS     ABSTRACT         A system for distributing utility service such as electrical power, telephone service and water to a plurality of spaced apart finger floats extending angularly from a floating mainwalk.  The floats are formed by rectangular concrete shells filled with a buoyant material and having a plurality of tie rods extending transversely through the floats with their ends projecting from the sides.  The floats are typically fastened to each other by elongated wales ex-tending along the sides of the floats which bridge the joints between adjacent floats.  In one embodiment the wales include inner and outer wale members separated from each other by a plurality of rectangularly shaped spacers. The spacers as well as the gap between the wale members are preferably cov-ered by an elongated cover.  Utility conduits extend along the gap between the inner and outer wale members and are sup-ported by the spacers.  Utility outlet fixtures are mounted on the wale members thereby allowing the utility conduits to be easily connected to the utility outlet since the utility conduits are positioned directly beneath the fixtures.  In another embodiment the spacers form a continuous beam extend-ing along the side of each mainwalk float.  The utility con-duits extend through the beam to a plurality of conventional utility outlets mounted directly on the beams.

Abstract: ABSTRACT OF THE DISCLOSURE:           Linear polydihalophosphazene polymers which are substantially free of gel are prepared by thermally poly-merizing a cyclic polyhalophosphazene represented by the formula (NPX2)3, wherein X is fluorine, chlorine or bromine in the presence of a catalyst which comprises the reaction product of a boron trihalide compound with an oxygenated phosphorus compound.         In addition to producing substantially gel free polymers, the catalyst composition of the process of the invention permits improved control of molecular weight, lower polymerization temperature, high rates of conversion of (NPCl2)3 to (NPCl2)n and provides for more readily processible and derivatizable polymers.

Abstract: ABSTRACT      A hardness tester includes a frame with a penetrator slidably carried by said frame for movement along a penetra-tion axis, and thereby adapted to form an indentation in a specimen upon application of a load thereto.  The resulting depth of the indentation is determinative of the hardness number of the specimen.  The means by which a load is applied to the penetrator is rotatably actuated.  The rotational dis-placement of the loading means bears a predetermined relation-ship to the linear dimension of the indentation depth formed during hardness testing of a specimen.  The hardness tester further includes electro-optical mechanical encoding means, and further adapted to emit a coded electrical signal indicative of the sensed angular displacement.  Furthermore, an electronic counting circuit decodes the output signals of the encoding means in the form of a count.  The count, determinative of the resulting depth of penetration, is indicative of the hardness number of the tested specimen. Optical numerical display means are also provided for visually displaying the specimen hardness number.

Abstract: ABSTRACT         The invention relates to an apparatus and method for quantitatively measuring the concentration of a first element or group of elements having substantially similar atomic numbers in a matrix comprising other elements having substantially different atomic numbers to that or those of the first element or group of elements.  The apparatus comprises:  (I) a source yielding gamma-rays, of sufficient energy for pair production; (II) a detector or detectors associated with the gamma-ray source which is capable of detecting 0.511 MeV annihilation radiation; (III) a measur-ing system capable of making a measurement of, or propor-tional to, bulk density; (IV) a shielding interposed be-tween the gamma-ray source and the detector or detectors in order to reduce the intensity of direct source gamma-rays impinging on the detector or detectors; and (V) a calculator to calculate the concentration associated with the outputs of the detector or detectors and the measuring system which measures bulk density or a property proportional thereto.          The measuring system for measuring bulk density or a pro-perty proportional to it must be located so as to make its measurement over substantially the same volume of the matrix as that in which the annihilation radiation origi-nates.  One suitable method for measuring bulk density over substantially the same volume is to measure the comption scattered radiation from the same source which is used to generate the pair production gamma-rays.

Abstract: J. Davis-l MULTIPLE LINE TELEPHONE INSTRUMENT            ABSTRACT OF THE INVENTION  The present invention is directed to a multiple line tele-phone instrument operative over a pair of data conductors and a pair of speech conductors using time division principles.  The data pair transmits line condition signaling and control using an asynchronous sixteen bit binary code while the speech and dialing information is sent over the speech pair of conductors in standard analog format for translation to PCM code within the system (not shown herein).  Line condition signaling between an instrument and its group logic circuit or group processor is in parallel over the data pair.  Incoming line condition signaling information is used to generate an audible signal and to illuminate a selected lamp representing the desired line.  Outgoing line condition signaling is encoded in diphase code using a square wave of a second frequency to represent a binary zero.  The outgoing encoding ensures that only one or the other binary signal is sent and to ensure that the sig-nals are sent in diphase mode.

Abstract: EAROM CELL MATRIX AND LOGIC ARRAYS WITH COMMON MEMORY GATE            Abstract of the Disclosure A three gate programmable memory cell comprised of a variable threshold memory element medial of two access gate elements, together forming a series path whose conductive state can be altered by any one of the series elements.  Each cell has lines for individually accessing the three gate electrodes, in addition to line connections to opposite ends of the conductive path formed by the elements in series.  In one form, an alterable threshold transistor is connected in series between two field effect transistors, one of the two controlling cell addressing and the other actuating the read mode.  The cell is erased with a high voltage pulse on the memory line.  Subsequent programming of the cell is defined by the voltage states on the word and bit lines of the addressing transistor in time coincidence with an opposite polarity, shorter duration pulse on the memory line.  The logic state stored in the cell is defined by the presence or absence of a conductive path through the cell when all three gates are biased to their read mode levels.  A unitary configuration of the cell includes a single substrate, with a channel defined between doped node regions.  Electrically isolated gate electrodes of the three transistors are symmetrically disposed adjacent each other over the channel to control its conductivity in segments.  The cells are amenable to being grouped in arrays, while retaining the independence of the high voltage memory line and the flexibility of individual row and column addresses.
