Abstract: ABSTRACT OF THE DISCLOSURE         A process for producing a fruit preparation from a natural fruit juice, the process comprises removing water from the juice by flowing the juice on a heated, recipro-cable, inclinable surface to reduce the water content to 10 to 25% by volume.  A crystalline modifying agent is then added to the product.  The modifying agent and the product are then blended while heating them.  The heating and blending is continued until the water content of the product is in the range of 1 to 15% by volume.  An apparatus for producing the preparation is described.  The apparatus has a concentrator pivotably mounted at about its center.  An end of the vessel can be raised and lowered to reciprocate the vessel about the pivotable mount.  The vessel is heated and has a closable outlet at each end. Extractors for vapour produced from the fruit juice heated in the first vessel are provided and blender means to blend the material produced on the concentrator with an added material.

Abstract: Abstract of the Disclosure Apparatus for calibrating a meter prover is disclosed including a chamber taking the form of a substantially perfect right circular cylinder, a piston adapted for rectilinear movement within said cylinder between a first position and a second position, means for moving the piston from its first position to its second position, and an encoder coupled to the piston for providing an output signal indicative of the movement of the piston and thus the volume of fluid displaced by that movement of the piston.  The calibrating apparatus comprises an antenna disposed within the chamber and a generator coupled to apply electromagnetic energy to the antenna whereby electromagnetic waves are emanated into the chamber.  A detector is coupled to the antenna to detect electromagnetic energy leaving the chamber and is in turn coupled to a resonant detector in the form of a cathode ray tube, whereby a minimum of the level of the electro-magnetic energy may be determined.  Further, a frequency detector in the form of a counter, is connected to the output of the generator to detect the frequencies of the generator output at which the minimum level occurs as observed upon the cathode ray tube corresponding to the establishment of a resonant standing wave within the chamber of the meter prover.  The frequencies at which the resonant standing waves are established within the chamber, in turn determine the volumes corresponding to the first. and second positions and therefore the difference in volume between the first and second positions corresponds to the displacement volume as would be drawn by the movement of the piston from-its first to its second position through the fluid flow meter under test.

Abstract: MOAT GUARDED JOSEPHSON DEVICES ABSTRACT In superconductive circuitry including a super conducting ground plane, a magnetic flux trapping moat is provided which surrounds a superconductive device. The moat is preferably a cut through the superconducting ground plane which extends along a perimeter surrounding the superconducting device, the moat being continuous except for small regions where there is no cut. The small regions serve as current carrying portions to link the ground plane within the moat to the rest of the ground plane outside of the moat. The moat is a flux pinning center so that magnetic flux does not enter the ground plane region located near the superconducting device. In a Josephson circuit, the Josephson tunnel devices are especially sensitive to trapped magnetic flux in the ground plane, and the provision of a moat around each of the devices prevents flux from moving into the ground plane areas near the devices and becoming trapped therein.

Abstract: SHIELDED HEATING ELEMENT HAVING INTRINSIC            TEMPERATURE CONTROL          ABSTRACT          A heating element consists of a  substrate  or core of a non-magnetic material having high thermal and electrical conductivity,   clad   with   a  surface  layer   of   a ferromagnetic  material  of  relatively  low  electrical conductivity. When the heating element is energized by a source  of high frequency alternating current,  the skin effect  initially confines current flow  principally  to the   surface  layer  of  ferromagnetic   material.   As temperature   rises   into  the  region  of  the   Curie temperature of the ferromagnetic material,  however, the decline in magnetic permeability of the  ferromagnetic material  causes  a  significant lessening of  the  skin effect,  permitting  migration of current into the  high conductivity non-magnetic core,  thereby  simultaneously enlarging  the cross-sectional area of the current  flow path   and  expanding  it  into  the  highly  conductive material; whereby the resistence of the heating material becomes  less,   due  to  both  effects.   However,  the structure  is  shielded  by the provision  of  an  outer layer,  the  thickness  of  which  will  depend  on  the frequency  to  be  employed,   whereby   electromagnetic radiation from the structure is substantially precluded.          Preferably, the thickness of the outer layer is at least three  (3)  skin  depths,  and usually five to  10  skin depths.
