Abstract: Abstract of the Disclosure A device is provided herein for transporting and emptying very pure liquid chemicals capable of reacting with constitu-ents of the atmosphere.  The device includes a container which has an upper part connected to a lower part by a flange having seals interposed between the container and the flange.  The upper part of the container has filling and emptying tubes extending into the container. The emptying tubes have rupture valves located therein for preventing contact between the very pure liquid chemicals in the container and constituents of the atmosphere which may be present in the top portion of the emptying tubes prior to emptying of the device.  Thus, chemicals of very high purity may be filled into and emptied from such container.

Abstract: ROTOR MEASUREMENT SYSTEM USING REFLECTED LOAD TRANSMISSION     Abstract of the Disclosure An apparatus is provided for obtaining data from sensor measurements made on a body moving rotationally with respect to a stationary observer.  Reactive means couples radio frequency energy between an energy source fixed with respect to the observer and load varying means located on the moving body.  The load variance is dependent upon measurement data provided by sensors located on the moving body.  The variation in load is reflected back through the reactive coupling means to detection means which is fixed with respect to the observer   The detection means operates to provide signals indicative of the measurement data provided by the sensors.  The apparatus of the present invention may be easily retrofitted to rotational devices such as turbines, motors and generators to provide relevant, continuous, on-line measurements of important parameters associated with such rotating systems.  These parameters include such measurements as temperature, pressure, strain and torque. Because of the reflected load nature of the formation transmission, only a single coupling is provided and this coupling serves to carry both power and information signals.

Abstract: ABSTRACT OF THE DISCLOSURE         A thermally insulated masonry wall comprises a plurality of thermal insulating barrier layers embedded in the wall in juxtaposition with each other and extending laterally inwardly from the surface of the wall.  The method utilized to obtain such an insulated wall involves providing a stream of air and injecting into the stream a thermal insulating liquid so as to form a stream of a thermal insulating liquid-air mixture.  The mixture stream is applied to the surface of the masonry wall so as to provide a first thermal insulating barrier layer embedded in the wall and spaced laterally inwardly from the surface of the wall.  The liquid-air mixture stream is applied to the wall surface a second time so as to provide a second insulating barrier layer in juxtaposition with the first layer and extending laterally inwardly from the wall surface to the first layer.  Thus, the masonry wall is provided with a thermal insulating layered barrier resulting from the coating of the particles of the masonry wall with the thermal insulating liquid and entrapping the air therebetween.

Abstract: CARGO SECUREMENT DEVICE               ABSTRACT OF THE DISCLOSURE         A container pedestal for supporting and securing a cargo container having a catch opening on a vehicle such as a rail car.  The pedestal includes a base defining a platform for supporting the container.  A pivotal latch lever is biased by a spring into a latched position wherein a latching nose on the lever registers with a latch recess in the container. The latch nose is contacted by the container for pivoting the latch lever from the latched to a released position when the container is raised or lowered.  The latch lever is mounted for vertical movement as well as pivotal movement, and inter-facing locking surfaces are provided on the latch lever and on the pedestal base for preventing pivotal movement of the latch lever out of the latched position when the latch lever is in an upper position.  The spring biases the latch lever upwardly to maintain the locking surfaces normally in engage-ment so that, when the latch lever is in its upper position, the container cannot pivot the latch lever.  If a container is lowered into the pedestal with the latch lever in the upper position, the container moves the latch lever downwardly to separate the locking surfaces and permit the latch lever to pivot to the released position for automatic loading of the container.  A cam is selectively operable to hold the latch lever in its lower position wherein the locking surfaces are separated and the latch lever can be pivoted by upward or downward movement of a container.  A line contact between the latch lever and the spring provides a uniform spring lever arm length.

Abstract: INTEGRABLE LARGE DYNAMIC RANGE PHOTODETECTOR          ELEMENT FOR LINEAR AND AREA INTEGRATED CIRCUIT IMAGING ARRAYS     Abstract of the Disclosure An integrable photodetector element of large dynamic range includes a silicon substrate which has a resistivity of between 1 and 100 ohm-cm.  The substrate is of one conductivity type.  In the substrate there is an electrically floating photosensitive diffusion region and a second diffusion region that is spaced apart from the electrically floating region by means of a channel in the substrate.  The two diffusion regions are of the same conductivity type and of opposite conductivity type to that of the substrate.  A metal-insulator-semiconductor gate spans the substrate between the regions and over the channel.  The gate is electrically connected to the electrically floating region, and the second region is reverse biased with respect to the substrate.  Except for the photosensitive diffusion region, the element is shielded against penetration by visible light.  The length of the channel between the regions, the resistivity of the substrate, the magnitude of the reverse bias and the depth of the diffusion regions is selected so that the potential barrier between the electrically floating region and the channel is low enough that electrons which are photogenerated in response to visible light impinging on the electrically floating region can be injected therefrom into the channel to be collected by the second diffusion region.  As a result of this the voltage of the electrically floating region varies logarithmically with changes in visible light incident thereon.

The second plate is slidable with respect to the first plate along a path which substantially bisects the apex angle, and the passage-ways and plates are so located that, as the second plate and collector passageway move along the path in the direction in which the apex angle points, the feeder passageway is gradually closed by the further surface of the collector passageway.  In a preferred embodiment, the collector passageway is triangular.

Abstract: ABSTRACT      Polyols, in particular polyglycerol, are esterified using a fatty acid at atmospheric pressure or under slight vacuum.  The reaction is carried out under an inert atmosphere at high temperatures (220°C-260°C) using an alkaline catalyst.  When the free fatty acid level decreases to less than 1%, the reaction mixture is stripped of substantially all the water by reducing the pressure within the vessel.  The alkaline mixture is then neutralized using a mild acid, e.g. phosphoric acid, while maintaining the high temperature and reduced pressure.  The mixture is rapidly cooled to below 177°C after the neutralization step.  The polyglycerol or polyol esters prepared via this process are of consistently high quality and are not subject to compositional changes during the process or on storage.

Abstract: Abstract Alignment of the [001] crystal axis of a face cen-tered cubic metal with the primary z axis of a single crystal axticle provides good thermal fatigue resistance along the z axis, and minimizes cracking transverse to the axis.  However, significant cracking is still ob-served parallel the z axis in severe applications.  This cracking can be reduced by controlling the secondary crystallographic orientation (i.e., orientation of crys-tal axes within x-y planes transverse to the z axis), to make the [110] crystal axis tangent to the article surface in the region most prone to thermal fatigue cracking.  Algorithims derived from empirical relation-ships enable calculation of the orientation likely to produce improved fatigue resistance.  More durable single crystal gas turbine blades result when the [110] crystal axis is made tangent to the blade surface in the critical crack prone regions just behind the lead-ing edge of the airfoil at about 40-80% of the airfoil span.  A representative improved gas turbine blade will have a secondary orientation angle .alpha. of -10 to +20 degrees, where .alpha. is the angle between the [100] crystal axis and the y axis.
