Abstract: ABSTRACT OF THE DISCLOSURE             A log surface determination technique involves optically measuring a tree stem and accurately separating the image of the tree stem from adjacent background, determining the true surface of the stem, eliminating discontinuities or anomalies, and identifying the ends of the stem, thereby making more accurate the definition of diameter measurement planes and more accurate edges or sides of the stem for permitting a more precise evaluation of the tree stem to obtain optimal board feet yield. The tree stem is optically scanned to produce data representative of a series of adjacent optical slices through the stem, with successive optical slices of the tree stern being aligned with one another to produce a composite picture of the surface of the stem which may include a number of edges containing both the size of the stem and anomalies such as branch stubs, bark chips, etc.          Through a refinement algorithm, employing an X-shaped filter, the existence of a true edge or side of the stem can be identified as contrasted to anomalies which would otherwise produce erroneous data for subsequent tree stem evaluation. Through this filtering process, once the anomalies are removed, gaps in the outline of the tree stem which result from the filtering process are filled in by an interpolation procedure based upon adjacent portions of the stem edges.

Abstract: ABSTRACT A process for producing an anhydrous aluminum chloride composition from a water-based aluminous material such as a slurry of aluminum hydroxide in a multistage extraction process in which the aluminum ion is first extracted into an organic liquid containing an acidic extractant and then extracted from the organic phase into an alkali metal chloride or chlorides to form a melt containing a mixture of chlorides of alkali metal and aluminum   In the process  the-organic liquid may be recycled.  In addition  the process advantageously includes an electrolysis cell for producing metallic aluminum and the alkali chloride or chlorides may be recycled for extraction of the aluminum from the organic phase.

Abstract: METHOD OF REMOVING ORGANIC CONTAMINANTS                  FROM AQUEOUS COMPOSITIONS                      ABSTRACT OF DISCLOSURE     A method is provided of removing organic contaminants from an aqueous composition contaminated therewith.  The method com-prises contacting the aqueous composition with a sufficient amount of organoclay for a sufficient amount of time to absorb a substantial portion of the contaminant, and to form an aqueous organoclay admixture.  The organoclay and aqueous composition are then separated from each other.  The method is particularly useful for separating oily contaminants from water toxic substance precursors, e.g. humic acid and toxic organics (e.g.          PCB) from water.

Abstract: -i-Abstract of the Disclosure Present day amalgam carriers include a separate spring member for urging the dispensing lever to its original position after serving to dispense the amalgam or restorative material into a prepared cavity, for example.  Fracturing of the spring member occurs periodically and replacement thereof in the carrier, even if replaceable, is a time-consuming and frustrating operation and demands digital dexterity.  The present invention provides an improved amalgam carrier wherein the spring and dispensing lever form an unitary member which requires infrequent replacement, if any, and when so replaced, or any other replaceable component of the carrier, may be done with comparative ease.

Abstract: ABSTRACT OF THE DISCLOSURE:         Ventilating unit comprising a housing to the front of which is fitted, preferably pivotably, a cover-flap.  The front of the said housing comprises a wall closes off the interior in which a fan is arranged. Known ventilat-ing units of this kind contain, inside, a plurality of com-ponents, more particularly a fan, insulating material, an actuator, etc..  These components have hitherto been secured to the housing, and to each other, by means of screws or other attachment-elements, resulting in relatively high material and assembly costs.  Furthermore, cleaning of the ventilating ducts, involving opening-up the unit, has been possible only by using trained personnel. In order to over-come this problem it is therefore suggested that the wall be built as an inspection-flap which is hinged to the front edge of the housing and is provided with means for locking it to the said housing.  In this connection, the fan housing is designed, or bears against the said inspection-flap, in such a manner that when the latter is locked, the said fan-housing is also locked in the housing.  Finally, at least one retaining wall is preferably provided inside and this, together with the said inspection-flap, produces a ventilat-ing unit with adequate stability.

Abstract: PREPARATION OF RESORCINOL AND SUBSTITUTED RESORCINOLS BY LIQUID-PHASE DEHYDROGENATION OF 1,3-CYCLIC DIONES DERIVED BY VAPOR-PHASE CYCLIZATION OF DELTA-KETO CARBOXYLIC ACID ESTERS     Abstract of the Invention A process is disclosed for making resorcinol and substituted resor-cinols by a first reaction step of vapor phase cyclization of a delta-keto carboxylic acid ester over a carbon catalyst bed to form a 1,3-cyclic dione intermediate.  The delta-keto ester is conveyed through the catalyst bed by a vaporized carrier characterized by being liquid at 25°C and having a suffi-ciently high boiling point that the vaporized carrier is easily condensable under ambient conditions.  In a second reaction step, a liquid solvent containing the 1,3-cyclic dione intermediate is contacted with a supported noble-metal catalyst to form resorcinol or a substituted resorcinol.

Abstract: ABSTRACT OF THE DISCLOSURE           A multicomponent feed mixture may be separated into its components continuously by injecting said feed mixture and a carrier fluid into a magnetically stabi-lized  fluidized  bed  containing adsorbent particles admixed or composited with magnetizable particles.  The bed particles continuously move transverse to the flow of the carrier fluid, which serves to fluidize the bed, such that the components of the feed mixture are trans-ported downstream varying distances from the injection point depending  upon the adsorption and desorption characteristics  of  said  components.   Product  streams comprising a portion of the carrier fluid and a portion of the feed mixture containing at least a portion, preferably a major portion, of one of the components can then be recovered from the surface of the bed, the most strongly adsorbed component being transported (and thus recovered) farthest from the injection point.

Abstract: A regulator system for both the Diesel and the electric portions of a Diesel electric locomotive allowing more reliable operation at all locomotive speeds. Said regulator has a regulator to regulate the electric power by varying the excitation (43) of the main generator by means of orders coming from a driver control (1, 8) which set a reference current level and (17) a voltage reference level (19) for the main generator and a Diesel engine gas oil reference level (18). These levels are compared with measurements of true corresponding values (24, 30, 27) and orders (43) for increasing or decreasing excitation are delivered so that the excitation of the main generator remains inside the scope delimited by the various reference levels and a Diesel power regulator which sends out orders to increase or decrease the gas oil injection in accordance with a predetermined Diesel engine speed/injection law and in comparison with the true measurements of the injection and of the Diesel engine speed.

Abstract: ABSTRACT         An infra red photo detector system comprises a piece of detector material, such as CdxHgl-xTe, InSb, InAs, egc, carrying at least a pair of spaced electrodes.  An optical arrangement directs a small spot of radiation onto the detector.  The position of the small spot on the much larger detector is found by applying an electrical bias between the electrodes causing a drift of photo carriers.  The bias may be of alternating polarity and the detector output measured at each polarity.  Alternatively, a high frequency bias may be applied and the A.C. offset from the detector used to indicate spot position.  Alternatively the spot position may be modulated or swept along the detector by a mirror moving in a saw tooth scanning action.
