Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a method of producing ceramic-form-ing oxide powders with variable and predetermined sinter-ing characteristics such as MgO,  BaO,  Ta2O5,  ZnO,  CeO, SnO, CaO, Cr2O3, CoO,  As2O3,  Sb2O3,  ZrO2,  TiO2,  ThO2 Y2O3, SiO2, UO2, A12O3, and Tio2.  There is a relationship between  sintering  rate  of oxide powders produced from metal alkoxides and degree and nature of hydrolysis.  This relationship  between  the  degree  of  hydrolysis  of  the corresponding alkoxide and the density of the resulting oxide is determined by hydrolyzing several samples of the alkoxide  using  different  amounts  of  water  in  diluted systems.  The samples are sintered to produce the metal oxide and its density is measured.  A desired density can then be achieved by using the amount of water of hydroly-sis which corresponds to that density.  Oxide powders with very high rate  of  sintering characteristics  can be a-chieved by using at least 5 moles of water of hydrolysis per mole of alkoxide.

Abstract: ABSTRACT:          The apparatus comprises a cylindrical carrier (1) which is rotatable about a supporting shaft (5) and is provided with n transducers (3) regularly distributed around its periphery, a first display device (35) for the display of a circular sector scan ultrasonic image with m radial picture lines in the B-mode, and a second display device (37) for an M-mode display of an ultrasonic image which consists of images relating to a single selected picture line (k) of the former image relating to succes sive instants in time, the successive line images being arranged parallel to one another with the same interline spacing. In order to obtain a line image repetition quency in the M-mode for the selected picture line (k), which is n times greater than the picture frequency in the B-mode, the device is arranged so that each of the n tran-sducers provides data for the formation of a corresponding group of mn picture lines during one revolution of the carrier, the transducers taken as a whole together provid-ing the data for all m picture lines. The image is formed in the B-mode by an n-fold line interlace (e.g.fig.4 where n-4). Each time any one of the transducers is in a position to provide data concerning the selected picture line (k), the formation of the image in the B mode is interrupted, the relevant transducer is activated to form the selected picture line (k), and transmitter pulses relating to any of the (n-l) lines following the selected line in the numerical sequence of lines, is suppressed.

Abstract: ABSTRACT OF THE DISCLOSURE:     A room-heating stove comprising:  a combustion chamber and a plurality of coaxially nested tubular ceramic columns rising above said combustion chamber and including an innermost column, a middle column and an outermost column.  The innermost column forms a central channel carry-ing off flue gases evolving from the combustion chamber, the middle column being a boundary of an intermediate channel in which the flue gases ascending in the central channel are guided downward, the outermost column bounding an external channel.  A metallic partition coaxial with the columns radially subdivide the external channel into an annular inner section and an annular outer section.  The inner section communicates with the intermediate channel for conducting the flue gases upwardly toward an exhaust near the top of the outermost column.  The outer section is open at the top and at the bottom thereof toward the surrounding atmosphere for conducting a flow of ambient air to be heated by the rising flue gases in the inner section through contact with the metallic partition.  At least the innermost and middle columns consist of superposed rings of heat-storing refractory material.

Abstract: ABSTRACT      A method and apparatus for treating ground and ground water contaminated with hydrocarbon and halogenated hydrocarbon compounds.  Treatment of contaminated water removed from the ground is accomplished by microorganisms which consume the contaminants.  Growth of microorganisms is enhanced under controlled conditions by addition of nutrients and gases such as oxygen, nitrogen, carbon dioxide or a combination of these and other gases to the contaminated water.  Treated water carrying microorganisms, nutrients and gases is returned for recirculation through the contaminated area of ground to leach out and biodegrade the contaminants deposited in the ground.  Microorganism activity is also enhanced in the ground by injection of nutrients and oxygen or ether gases into the ground and ground water in the contaminated area.

Abstract: ADJUSTABLE END WRENCH WITH RELEASABLE LOCKING FEATURE      Abstract of the Disclosure A thumb adjustable, parallel jaw end wrench, that uses a worm gear and a movable jaw with a rack, is provided with a locking feature.  The worm gear is so mounted in the fixed jaw portion of the wrench that it has play in its axial direction.          A first hole ("cam follower hole") that extends perpendicularly away from the head end of the gear is intersected by a second hole ("cam pin hole") running perpendicular to the cam follower hole. Biasing means urge the worm gear toward the cam pin hole.          A cylindrical pin having a cam surface with high and low posi-tions that extends radially around a central segment of the pin is rotatably mounted in the cam pin hole.  Cam follower means slidably mounted in the cam follower hole ride on the cam surface and extend to the head end of the worm gear.  To lock the wrench's grip on an object, the pin is turned to its high cam position, causing the follower means to push the gear, and therefore the rack and movable jaw as well, toward the fixed jaw.

Abstract: ABSTRACT            In touch sensing keyboards which use the capacitance of the human operator to vary the characteristics of a resonant circuit thereby inputting data corresponding to a specific keyboard electrode touched by the operator, problems arise because the "steady state" capacitance varies from electrode to electrode.  The sensing circuits may, as a consequence, fail to identify a touch condition in respect of one or more of the keyboard positions.  The invention overcomes this by compensating for the capacitance variations basically by providing a ROM which switches in a different compensating capacitance as necessary for each specific keyboard location.

Abstract: TITLE               APPARATUS FOR MONITORING REFRACTIVE                   INDEX CHANGES IN FLUIDS     INVENTOR                  Jacques P. Legendre ABSTRACT OF THE DISCLOSURE           The apparatus for monitoring refractive index changes in fluids includes an optical fiber with one end forming a probe for contact with the fluid to be monitored, a source of optical energy to be directed into the fiber from the other end and a device for detecting reflected light from the fiber probe end. The probe end of the fiber has a planar surface normal to the axis of the fiber.  The refractive index discontin-uity between the probe end surface and the fluid causes a portion of the optical energy transmitted through the fiber to be reflected back through the fiber.  The reflected optical energy which is detected, is directly related to the refractive index of the fluid.
