Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a carton especially adapted to package single servings of pie.  The carton has a triangular shape due to a triangular top closure and a bottom support panel.  A trapezoidal end wall connects the top and bottom panels at the bases of the respective triangles and slants outwardly from bottom to top.  The bottom panel has inner side wall panels at-tached to it.  The inner side wall panels are secured in a ver-tical upright position by means of corner flaps which are pre-ferably secured to the outer surfaces of the inner side wall panels.  The top closure panel has downwardly extending outer side walls which telescope over the inner side wall panels.          The fragile pie crust is protected by the slanted end wall, overlapping corner flaps, and arcuate or rounded surfaces as required, at the juncture of the end wall and/or outer side wall panels with the top closure panel.

Title: Method and apparatus for tidal electric power  generation using the buoyance energy of the tide
Inventor: CHOI IN K

Abstract: ABSTRACT   The present invention relates to a method and apparatus for tidal electric power generation using the buoyancy energy of the tide.  The present invention includes a buoyant container having a balancing buoyant chamber and a flood gate, a power transmission apparatus having a converting apparatus, and a four-way valve.  The buoyant force of the buoyant container is decreased during the upward movement of the container while the kinetic energy decreases during the downward movement of the container.  With control of the four-way valve, the decreasing buoyancy force is partially compensated for by the pumping of water from the buoyant container and the kinetic energy is reinforced by filling the buoyant container with water.  The converting apparatus comprises two conic helical gears.  By using the conic helical gears, the buoyant force and the kinetic energy are constantly transmitted to the pump.  A brake holds the buoyant container at a height where the weight of the buoyant container balances with the buoyant force.  At the ebb and flow of the tide, the brake is released and instantaneous force is produced.  By virtue of the present invention, greater energy can be obtained with little energy loss by comparison with conventional systems of this general nature.

Abstract: METHODS FOR DETECTING AND IMAGING A, TEMPERATURE OF AN OBJECT BY NUCLEAR MAGNETIC RESONANCE            ABSTRACT OF THE DISCLOSURE     A novel and improved method to detect indirectly a temperature of an object employing nuclear magnetic resonance techniques (NMR).  The method involves obtaining an NMR spectrum to determine chemical shift, relaxation times, spin-spin coup-lings or quadrupole couplings for an element of a compound having at least one conformational isomer wherein the compound is influenced by a temperature of the object.  Uniquely, the present invention may detect temperature in the body of an animal.  Further, the present invention discloses a novel method to determine and monitor thermal physiological states in an animal as well as determine and monitor thermal states in an object.  Because of the unique and advantageous non-invasive, non-destructive and non-ionizing properties, the present inven-tion may be employed in an object or animal continuously.  The preset invention also provides for the thermal imaging, or NMR thermography, by one-, two-, or three-dimensional reconstruction techniques from chemical shift, relaxation times, (e.g., T1 or T2,) spin-spin couplings and quadrupole couplings for an element of a compound having at least one conformational isomer in an object or animal influenced by a temperature in the object or animal.  The methods disclosed are applicable to inanimate and animate solids.

Abstract: EIGD Limited                 80/2079/04 An Infrared Absorption Gas Detector ABSTRACT OF THE DISCLOSURE          An  infrared absorption gas  detector uses  the amount of infrared radiation of a particular wavelength to give an indication of the presence of a particular component or a particular gas.  A monitoring head for such  a  detector  includes  a  source  (8)  of  infrared radiation, two detectors (17, 18) for detecting infrared radiation formed by the two elements of a dual element detector,  an  optical  path  which  extends between  the source (8) and the elements (17, 18) of the detector and which  includes  a  gas  sample  volume,  and  selectively transmitting  spectral  filters   (20, 21)   immediately infront of the dual elements (17, 18) of the detector to filter the radiation impinging on the detectors (17, 18). The optical path also includes converging means  (9)  to provide a converging beam of radiation concentrated onto both elements (17, 18) of the dual element detector.  The location of the gas sample volume, the separation of the two elements (17, 18) of the detector, and the converging means (9) are arranged so that infrared radiation emitted by the source (8) and impinging upon each of the elements (17, 18) of the detector follows a substantially common path through the gas sample volume.  The monitoring head operates, in effect, as a single beam in both space and time whilst having no moving parts whatsoever.

Abstract: ABSTRACT             This invention relates to apparatus and a method of controlling the amount of delay or phase-shift which is applied to a signal received at or transmitted from each transducer in a multi-transducer antenna to produce a beam directed at a specific target point.  For each transducer a first look-up table is used for storing first digital words representative of the included angle between the lines joining the target to a reference point, and the same reference point to a transducer.  A second look-up table is associated with the first look-up table for each transducer, and stores second digital words representing delay or phase-shift control signals corresponding to ranges of the target relative to the reference point for each of said first digital words.          Each first look-up table is addressed with an address signal representing the direction of the line from the reference point to the target, to obtain a corresponding first digital word.  Each second look-up table it addressed with a corresponding first digital word combined with a signal representing the range of the target to obtain a corresponding second digital word. A signal received or transmitted by the corresponding transducer is delayed or phase-shifted an amount represented by the second digital word.
