Patent CA-1038059-A (CA)

Abstract: ABSTRACT     A liquid level gauge which utilizes the electrical resistance of the liquid being gauged to provide readings. An immersion unit is adapted to be disposed vertically in the liquid storage vessel. It comprises an elongate conduc-ting member coextensive with a row of insulatedly-mounted electrodes which letter are individually connected to an indicating type selector switch means. The conducting member is connected to one input of an extremely sensitive electronic amplifier, which in turn drives an output indi-cating meter. The indicating selector switch means can apply an energizing voltage to any of the electrodes, which results in A driving signal applied to the amplifier only if the energized electrode is submerged. An indicator light signals the amplifier output under such circumstances. By sweeping the selector switch means over its range and noting the point at which the indicator light becomes illuminated, it is possible to acertain the location of the upper-most electrode which is submerged and thus determine the level of fluid in the tank. In addition, the indicating meter provides a reading corresponding to the percentage or portion of the electrode which is submerged, and thus gives a finer degree of accuracy to the level measurement. An electrical guard surrounds the conducting member and elec-trodes, and means are provided for maintaining both the guard and the electrodes which are not energized at a potential equal to that sensed by the conducting member. The advantage of the present device over prior types is that the potential which the conducting member senses is not adversely influenced by proximity of the immersion unit to other objects in the tank.  Improved reliability and accuracy are thus realized.

Abstract: IMPROVED PROCESS FOR MAKING NODULAR IRON AND AFTER-TREATING ALLOY UTILIZED THEREIN                   Abstract of the Disclosure An improvement in a process for making nodular iron is dis-closed.  Prior to casting, an iron melt which has previously been contacted with a graphite-spheroidizing agent is further con-tacted with an after-treating alloy agent containing about 0.8 to about 1.8 weight percent magnesium.  Magnesium utilization in the pre-casting step is unusually high and the amount of graphite-spheroidizing agent can be substantially reduced with-out detrimentally affecting the metallurgical or physical pro-perties of the resulting nodular iron product.  The after-treating alloy agent is also claimed.

Abstract: A gelatinized, palatable, nontoxic extrusion cooked ruminant feed is disclosed which contains a disrupted starch-bearing food source reacted with a nonprotein nitrogenous substance (NPN) and a quantity of lipid material such as animal fat which serves to greatly facilitate product performance and handling of the feed, especially when certain tuber or waxy starch materials are used therein or in the case of high pro-tein equivalent feeds where the starch-bearing material-NPN (preferably urea) ratio is on the order of 4 to 1 or greater. In addition, lipid addition synergistically acts to yield cooked products exhibiting derivable bacterial protein levels approxi-mately equal to or better than otherwise identical feeds free of added lipid notwithstanding the fact that extent of starch disruption and consequent gelatination within the feed is normally decreased by virtue of the lipid addition.  In pre-ferred forms, lipid in the form of animal fat or the like is added to the feed constituents in liquid form and in amounts ranging from 0.25 to 10% by weight prior to cooking of the feed in a conventional extrusion cooker, and the expanded and gelatinized cooked product is thereafter cut and dried to its final form as ruminant feed which can easily be shipped, stored and fed to ruminants as a high protein food source.

The halogenation reaction can be effected directly using phosphorus pentachloride or pen-tabromide or the 2-hydroxy group of the acyldiaminopropane can first be halogenated using phosphorus oxychloride, oxybromide, trichloride or tribromide or thionyl chloride to give the cor-responding 2-haloacyldiamine and the acyl group then halogenated using phosphorus pentachloride or pentabromide to give the imi-doyl halide so permitting intermediate purification of the haloacyldiamine.

Abstract: ABSTRACT      A Television tuning system has a ramp voltage source including an electrical current source and an electrical current sink coupled through selectively operable transmission gates for varying the voltage of a tuning capacitor to control a local oscillator for tuning independent of received signal.  The local oscillator signal is mixed with a received signal to produce an intermediate frequency signal which is amplified in an IF amplifier. A frequency detector is coupled to the IF amplifier and produces an error signal dependent upon the frequency difference between a reference frequency and the IF signal.  An additional current source and sink are coupled to the tuning capacitor through transmission gates controlled by the error signals.  Differences greater than a predetermined amount selectively activate the latter transmission gates to provide substantially constant magnitude tuning voltage corrections irrespective of the amount of the difference.

Abstract: ABSTRACT OF THE DISCLOSURE A finger jointing machine in which timber is fed on a horizontal support table and is clamped against this table  and against a vertical guide fence adjacent the table.  The timber is clamped with the rear end of one piece of timber spaced from the front end of a second piece of timber at a defined spacing. A cutting and gluing unit is movable vertically through the space and carries two rotatable cutters, rotatable about horizontal axes, each cutter having axially spaced teeth, the teeth of one cutter being axially spaced from those of the other by half the spacing between the teeth. The cutters are caused to rotate in opposite directions so that the teeth of one cutter engaging the rear end of the one piece of timber and the teeth of the other cutter engaging the front end of the other piece of timber are both moving upwardly as the cutting and gluing unit is caused to move upwardly.  The cutting and gluing unit also includes two ribbed gluing rollers arranged one below each of the cutters, the ribs of the gluing rollers being disposed directly below the teeth of the cutter thereabove, so that they pass through the groove formed by the respective cutter thereabove.  The cutting is effected by vertical upward movement of the cutters and support members are arranged which themselves have the shape of the fingers and prevent the wood from breaking out as the cutters pass up to the top surface.  These cutters are retracted immediately after the cutters have gone by so that glue is not deposited thereon.                    - 1a -

Abstract: ABSTRACT OF THE DISCLOSURE           A bearing assembly comprises a plurality of bearing shoes positioned to engage a slide member or a journal in supporting relation thereto, each bearing shoe having a bearing face con-forming to the surface of the member to be supported.  Each shoe is a composite member comprising a main shoe portion and a pair of auxiliary end shoe portions which are articulately con-nected to the main shoe portion and displaceable therefrom to dis-engage the member being supported.  Each bearing shoe is sym-metrically mounted with respect to a pivot, and the auxiliary shoe portions are selectively displaceable between operative and inoperative positions so as to establish an effective bearing face positioned to engage the member being supported, which bearing face is asymmetrically disposed in relation to the pivotal mounting.  The geometry of the bearing assembly is thus reversible.
