Abstract: 57 The invention relates to a new process for producing titanium IV and zirconium IV pyrophosphates, certain of which are new compounds, and their uses. The pyrophosphates are prepared by reacting a metal tetraester with phosphorus pentachloride, with or without the addition of an hydroxyl compound, such as an alcohol or a phenol. Depending on the molar ratio of the components, the compounds produced may contain cyclic or straight chain pyrophosphate groups and alkoxy groups attached to the metallic ion. In addition to forming new compounds, the process of the invention produces the desired products without difficult-to-separate by-products. The products of the invention are useful as flame-retardants, antioxidants, coupling agent, impact modifiers and processing aids, and the reaction for their preparation may be represented as follows:
     wherein M is titanium or zirconium; R is a monovalent hydrocarbon group optionally substituted with halogen or oxygen substituents; n is an integer from 1 to 4; m is an integer from 0 to 4; x is an integer from 0 to 2; q is an integer from 0 to 4; n is greater than or equal to m; n = p + m + q; x + m + 2p + q  =  4; and when x is greater than 0, q is 0.

Abstract: Disclosed herein is a process for the hydration of a nitrile compound. Owing to the use of a Raney copper catalyst having an iron content of 0.7 wt. % or less based on the copper component in a suspended state, the process allows the catalyst to retain high activity and facilitates the separation of the catalyst and liquid reaction mixture by sedimentation and/or filtration. In an example, a catalyst with 0.1 % iron achieved 67% conversion of acrylonitrile to acrylamide, whereas a catalyst with 1.56% iron achieved only 40%.

Abstract: An intermittent magnetic video recorder according to the present invention separates vertical synchronizing signals from composite video signals by a vertical synchronizing signal separation circuit (7) and generates correction vertical synchronizing signals different in frequency and phase from the vertical synchronizing signals from a correction vertical synchronizing signal generator (9) so that a drum motor (6) is rotated in synchronization with the correction vertical synchronizing signals by a drum controller (10), thereby to perform intermittent magnetic recording of the composite video signals on a magnetic tape by magnetic heads (3a, 3b) provided on the rotary drum 4. Therefore, even if the composite video signals are recorded on the magnetic tape which is fed at a speed slower than a prescribed speed or in a stopped state, the recording format of the recorded magnetic tape can be interchangeable with that recorded at the prescribed tape feed speed.

Abstract: The Czochralski single crystal growing of semiconductor silicon is performed in an apparatus in which a conically tapered tube having a downwardly decreasing diameter is installed to coaxially surround the growing single crystal keeping the lower end thereof with a narrow gap above the surface of the melt in the crucible. By virtue of the downward stream of a protecting gas flowing inside the tube, vapor of silicon monoxide is efficiently swept off as being carried by the gas stream so that the troubles caused by the particles of silicon monoxide deposit entering the melt is minimized. The tapered tube also serves as a heat shield and a heat conductor so that the cooling efficiency of the growing single crystal is increased and the velocity of single crystal pulling-up can be greatly increased.

Abstract: An onboard flight management system produces cost-effective trajectory target signals in response to an input desired time of arrival. Aircraft monitoring systems produce signals corresponding to real-time aircraft parameters including fuel flow rate, airspeed, windspeed, thrust, drag and mass. Stored in memory are aircraft characteristics including time cost, fuel cost, and acceleration due to gravity. A flight computer responds to an input desired time-of-arrival and the real-time parameters and stored characteristics signals and produces cost-effective trajectory target signals. The computer employs multiply regressed drag and fuel flow models which avoid trajectory discontinuities and the trajectory targets are produced using a Fibonacci search technique, which is computationally very efficient.

Abstract: A device is disclosed for forming a connecting transition between two perpendicularly adjoining surfaces, of which at least one surface is provided with a rigid covering, in particular ceramic tile. The device allows for compensation of the varying stresses occurring in the surfaces bounding the joint combined with adequate sealing of the area of transition. The device is intended to find application in particular as a connecting transition between the edge of a bathtub and the adjoining wall and consists of a single-piece plastic angular profile. A sealing strip with a softened sealing lip is molded onto a leg of the angular profile which is formed of hardened material so as to extend the leg. The sealing lip has an adhesive profile arranged on its outer side in the lengthwise direction of the angular profile. By virtue of its elasticity, the molded sealing lip of the single-piece profile is biased against the surface to be sealed. Because the sealing lip is kept connected to such surface by an adhesive connection, it always acts against such surface in a sealing manner.

Abstract: A two-fluid nozzle for atomizing a liquid-solid slurry which provides a plurality of atomizing gas streams which intersect the discharged liquid-solid slurry centripetally to effect high fidelity atomization of the liquid-solid slurry. The nozzle comprises an elongate central conduit (16) for the flow of the liquid-solid slurry and an elongate annular conduit (12) the cocurrent flow of the atomizing gas. The annular conduit (12) is coaxial with and surrounds at least a portion of the central conduit (16). In gas communication with the annular conduit is a plurality of discharge conduits (22b, 24b) each of which has an intermediate portion and an angled portion. The angled portion extends from the intermediate portion at an angle within the range of from 10° to 80° with respect to an outward extension of the longitudinal axis of the central conduit (16). The cross-sectional area for flow of each of the angled conduit is less than that of the intermediate portion   and the total cross-sectional area for flow of the discharge conduits measured at their intermediate portions is less than that of the annular conduit. By this decrease in the total cross-sectional area for flow from the annular conduit to the angled portions of the discharged conduits, the velocity of the gas being discharged from the nozzle is higher than the velocity of the gas as it passes through the annular conduit. This increase in gas velocity results in better atomization of the liquid-solid slurry.

Abstract: A reproducing machine in which an electrostatic latent image recorded on a photoconductive member (10) is developed with a liquid developer material comprising at least a liquid carrier (58) having pigmented particles (60) dispersed therein. The developed image is transferred from the photoconductive member to a sheet of support material (34). The sheet of support material having the developed image thereon is dried by the application of heat to remove substantially all of the liquid carrier transferred thereto. This application of heat causes the pigmented particles at least partially to melt. The pigmented particles are permanently fused to the sheet of support material in image configuration also by the application of at least heat. This technique avoids the formation of micro-voids.

Abstract: Diisopropyl ethers of oligomers of ethylene glycol having between 2 and 8 ethylene glycol moieties and an average molecular weight between 190 and 300, are more useful physical absorption solvents for the separation of acid gases than are dimethyl, diethyl, ethyl butyl, propyl butyl, dibutyl, or higher alkyl ethers of the same ethylene glycol oligomers, because of a combination of high solution capacity, high separation efficiencies, low viscosity, low gas pressure, and resistance to hydrolysis during use. The diisopropyl ether of diethylene glycol is especially advantageous for use at absorber temperatures below 0°C. Because of low viscosity, the diisopropyl ethers can often be substituted in separation equipment designed for use with chemical rather than physical solvents, thereby realizing the lower operating costs associated with physical solvents without requiring new capital investment.
