Abstract: ABSTRACT OF THE DISCLOSURE           This invention discloses a novel food container for the storage and transport of food, particularly hot food such as pizza.  It comprises an identical upper and lower portion, each portion having a flat, base surface, outwardly extending side walls with a circumferential lip therearound.  A locking means is carried on the lip to releasably lock the upper and lower portions together.  A plurality of vertical honeycombs are on the interior of the base surface and a plurality of buttresses are found in the interior side walls.  The device is preferably made of an expanded material such as polystyrene.          The device only requires a single mould to manufacture it and is an efficient, inexpensive and strong insulating container which has eliminated the problem of condensation within the containers of the prior art.

Abstract: COMBUSTIBLE  GASES  DETECTOR           ABSTRACT        A differential thermocouple combustible gases detector is provided by coating one thermocouple junction of a differential thermocouple pair with a catalyst and the other thermocouple junction with a non-catalyst.  Heated combustible gases re-act with the catalyst to liberate heat to the catalyst coated thermocouple junction in proportion to the concentration of com-bustible gases and proportionally raise the temperature of that junction above the non-catalyst coated junction.  The output signal from the differential thermocouple device is thus a sig-nal indicative of the concentration  of combustible gases.

Abstract: METHOD OF CURING CONCRETE     ARTICLES BY WATER VAPORIZATION     ABSTRACT OF THE DISCLOSURE Concrete articles to be cured are charged into a kiln.  A hot water bath is maintained on the kiln floor and the water is circulated through a heat exchanger and sprayed beneath the level of the concrete articles into the water bath to maintain the water bath at a temperature of 100-200°F to thereby maintain the internal kiln atmosphere at a humidity greater than 90% and at a sufficiently high temperature to effect hydration and hardening of the cement and due to the closed nature of the kiln, the temperature there-within can be maintained within 5°F from top to bottom.  The sprayed hot water supplies the needed heat energy and the water vaporization within the kiln provides the degree of moisture needed to cure the concrete articles.  As water rather than steam is used, less energy is needed to heat the water than required to generate steam so that the overall cost of curing the concrete articles is considerably reduced as compared to steam curing methods.

Abstract: ABSTRACT    A method and apparatus for printing electrographically upon two sides of a chemically pre-treated recording medium, at comparatively high speed such as is required in a computer print-out apparatus.    A pre-treated paper medium comprised of a conductively treated paper base supporting a plastic dielectric coating on each of its sides, is positioned between electrode assemblies comprised of matrices of a plurality of styli which receive variable information from a data processor, or other equipment and by selectively charging the plurality of styli generating a latent image of alphanumeric characters or other variable printing by electrostatic discharge on the paper which is re-tained by the coating.  The latent image is developed, i.e. made visible, by subjecting the paper medium to charged toning particles suspended in a liquid toning carrier.  The image is then fixed i.e. made permanent by vaporizing the liquid carrier with heat.

Abstract: ABSTRACT OF THE DISCLOSURE:           A combination fireplace enclosure and heat-exchanger unit of the retro-fit variety, for providing supplemental heat to room areas external to a fireplace, comprising an enclosure frame having closure doors, and a series of elongate heat-transfer members carried by the frame and constituted of relatively high thermally conductive material such as aluminum, disposed side by side, and having portions extending rearwardly from the frame in a position directly above the fire so as to absorb heat therefrom. Other portions of the members extend forwardly through an aperture in the frame and terminate as a series of spaced-apart radiating fins of relatively large expanse and disposed at the front of the frame. Air from the room is thus heated by these fins, through conduction and radiation. A ventilating hood is provided, to partially conceal the fins and shield them from inadvertent contact with personnel in the room. A baffle carried by the frame directs hot gases from the fire toward and past the absorption portions of the members, to maximize heat-transfer thereto. The closure doors carried by the frame minimize heat loss from the room, due to air therefrom being drawn up the chimney. As a result, there is realized higher heating efficiency than was possible with other heat-extracting units of the type intended to be used with fireplaces.

Abstract: ABSTRACT OF THE DISCLOSURE         A system is provided for monitoring sputtering deposition parameters and through closed-loop control achieving rapid modification of the parameters to maintain or to obtain a film composition.  In reactive sputtering, the sputtering chamber has individual gas pressure controllers for the various gases to be added to the chamber.  A holder for a substrate on which the film is to be deposited includes a heater with adjustable control.  A differentially pumped quadrupole mass analyzer interconnects with the chamber bottom to receive a sample of plasma ions, measures the ionized species existing in the plasma and generates signals related to the film composition. A controller responsive to the quadrupole analyzer actuation adjusts the pressure of the one or more reactive or non-reactive gases being provided to the chamber, and/or controls other deposition parameters, such as substrate temperature or other plasma features.
