Abstract: ABSTRACT OF THE DISCLOSURE     An emission computed tomograph provided with a collimator ring rotatable about an object being examined and having a plurality of slits for defining the direction of incidence of the radiation emitted from the object on the radiation detectors.  The slits are arranged circumferentially of the ring and directed at successively different angles relative to the radial direction of the collimator ring, so that as the ring is rotated, the object is tomocraphically scanned.  The collimator ring may be divided into a plurality of equal arcuate portions, in each of which the slits are directed toward  the object in parallel with each other, so that as the collimator ring is rotated to scan the object, only the parallel profile data thereof can be obtained.

Abstract: ABSTRACT    A loudspeaker horn having improving directivity has a pair of smoothly flared vertical sidewalls joined to a pair of smoothly flared horizontal sidewalls.  In an exemplary embodiment, one pair of sidewall is generated as a surface of revolution, with the curvature of the surface being defined by a power series formula.   The contour  of the remaining pair of sidewalls is also defined by the power series formula, although different constants may be used.   The vertical and horizontal sidewalls are separately defined and are substantially congruent at the rectangular or square mouth.   In the exemplary embodiment, the gap formed at the back of one of the pairs of sidewalls is connected to the throat formed at the back of the other pair of sidewalls by a connecting  section having  an arcuate area which mono-tonically increases from the throat to the gap.

Abstract: ABSTRACT OF THE DISCLOSURE         Relative rotational movement is allowed between two longitudi-nally extending articulated members connected by a joint, while at the same time longitudinal relative translation of the members is restrained.  Each joint is composed of two substantially identical halves with each half having parallel semi-cylindrical slots provided therein cooperating with the semi-cylindrical slots of the opposite half to form cylindrical apertures for receiving the longitudinally extending articulated members.  Each semi-cylindrical slot has a circumferential groove about its periphery.  The grooves of cooperating semi-cylindrical slots meet to provide a complete circumferentially extending groove for receiving a pin inserted through the member received in that aperture.  In this manner, rotary motion of the longitudinally extending member is allowed to a full 360°.  Each half of the joint contains a raised surface and a recessed surface for cooperating with the raised and recessed surfaces of the other joint half in order to properly align the two pieces to form a complete coupler joint.  The two pieces are held together by threaded connectors, such as screws, bolts, or the like.

Abstract: PROCESS FOR PREPARING A CITRUS FRUIT JUICE CONCENTRATE                   Rudolf G. K. Strobel Abstract of the Invention A process for preparing a natural citrus fruit juice concentrate prepared from natural citrus fruit ingredients is disclosed.  The fruit juice concentrate has at least 35% solids including pulp, non-volatile compounds, pectin and volatile compounds.  This fruit juice concentrate has at least 65% of the aroma and flavor volatile compounds of the natural juice.    The fruit juice concentrate is prepared by separating natural citrus fruit juice into a particulate solids portion (such as pectin or pulp) and a serum portion.  The serum portion which comprises 7% to 20% solids and from 80% to 93% water is concentrated by removing essentially pure water.  The concentration step can be accomplished by freeze concentration or by sublimation concentration.  When sublimation concentration is used, the particulate solids do not have to be separated from the serum.  Substantially 100% of the non-volatile solids are retained.  Moreover, the product is substantially free of oxidative degradation products.

Abstract: ABSTRACT   A degreasing apparatus which utilizes hot water under pressure from a sink faucet to inject a degreasing solution directly into a blocked U-trap or downstream sewerage system.  The degreasing apparatus consists of a small pipe elbow permanently affixed at one end to the output nozzle of a liquid dispenser and provided at the other end with a female hexagonal coupling nut for attaching the apparatus to standard U-traps.  To use the apparatus, the input of the liquid dispenser is coupled by a conventional washing hose to the hot water faucet of the blocked sink.  The output end of the degreasing apparatus is coupled to the input of the U-trap after the trap is uncoupled from the drain pipe of the sink.  After tightening the hexagonal coupling nuts of the U-trap, the degreasing apparatus permits the injection of a degreasing solution from the liquid dispenser container at maximum pressure into a blocked U-trap or downstream sewerage system relying solely on the water pressure pro-vided by the faucet of the sink.
