Abstract: This invention provides an ultrasonic transducer system which utilizes a reconfigurable delay line to perform a variety of processing functions. In particular, for a preferred embodiment, the delay line utilized to sum the outputs of transducer elements is reconfigurable to provide serial processing of image scan lines while providing parallel processing of Doppler color flow scan lines. More particularly, the echo signals generated in response to the packet of color flow lines utilized to generate color flow information are applied in a predetermined way to two separate portions of the delay line, the portions of the delay line having different delay profiles, the resulting outputs being focussed to slightly different points in the image and thus providing color flow packets for two separate points in response to the transmission of a single packet of color flow lines. This results in a substantial enhancement of the system frame rate.

Abstract: Whether a compound will thermoparticulate, that is, decompose to produce particles detectable by an ion chamber monitor or a condensation nuclei monitor and, if so, at what temperature, is predicted by determining the decomposition products of the compound, eliminating the compound if none of its decomposition products are greater than 25 .ANG., and using the temperature at which the decomposition products greater than 25 .ANG. have a vapor pressure of 10 millimeters as an estimate of the temperature at which the compound will decompose to produce products detectable by the monitor. Also disclosed are compounds which have been found to thermoparticulate at low temperatures.

Abstract: A method of removing heat from molten metal in which the metal is caused to flow freely within a gaseous media or vacuum over a body disposed within the metal stream such that any tendency for the metal to solidify during its passage is effective on the surface of said body against which the solidifying metal contracts into intimate contact therewith. The body may be forcibly cooled, e.g. by water. Accordingly, since the liquid metal is not enveloped by a channel or pipe, the solidifying shell tends to shrink on to the body, no gap is created, and this much higher heat transfer coefficients between the shell, the liquid metal, and the cooling body are achieved.

Soil moisture is measured by change in capacitance of the capacitance sensing probe.

Abstract: A downstacker assembly in which paperboard blanks, received from a die cutter station, are passed sequentially through a trim removal station, a feed station, a stacker assembly partially disposed in a pit, and a stack retrieval assembly. The stacker assembly is disposed in a drop chute beneath a vacuum conveyor assembly which drops the blanks from the feed station into the drop chute, assisted by a pair of twin blank striker assemblies which selectively separate the blank therefrom. The stacking blanks are tamped using a semiflexible tamper plate assembly against flexible curtains on a descending elevator assembly. A stack staging assembly serves as a temporary cradle to catch the falling blanks once a predetermined stack height is achieved until the stacks can be removed via the stack retrieval assembly. A dunnage holding assembly provides multiple-tier load forming as the stacks are discharged from the downstacker assembly.
