Abstract: ABSTRACT OF THE DISCLOSURE           An improved curable epoxy resin composition of a vicinalpolyepoxide and an effective amount of a novel poly-ether urea curing agent is disclosed.  The improved curable epoxy resins which are  useful as coatings, castings, seal-ants, and adhesives show improved tensile shear strength, flexural strength, and ultimate elongation.  The novel polyether urea curing agents of the instant invention are characterized by terminal primary amino groups and are formed by reaction of polyoxyalkylenepolyamines with urea, urea forming compounds, or bifunctional isocyanates.         A preferred curing agent includes a mixture of a novel polyether urea formed by reaction of a polyoxy-propylenepolyamine having a molecular weight of from about 200-2000 and an effective amount of urea; and another known epoxy resin curing agent such as a polyoxyalkylenepolyamine in ratios of from about 5:1 to 1:5 by weight.

Abstract: ABSTRACT OF THE DISCLOSURE      A pea harvester incorporates a threshing device and a system, known per se, which maintains the device in a fixed orientation in space irrespective of the ground contours. To feed the threshing device a series of conveyors is pivoted so that these can continue to supplier the threshing device without crop loss even if a local ground irregularity deflects a forward pick-up reel which discharges on to a first one of the conveyors.      The pick-up reel has a width at least equal to the widest track of the harvester wheels and the first conveyor has substantially the same width. A number of cleaning stages is incorporated and peas are received from the threshing device by two inclined vibratory conveyors the inclination of each of which is adjustable.      A hopper assembly for peas is arranged forwardly of the threshing device and includes an auxiliary hopper which automatically takes the place of the main hopper when the latter is moved to its discharge position.

Abstract: ABSTRACT A sliver opener roller for use in textile machinery comprises a replaceable clothing sleeve, a roller body, and a clamping ring screwed to the roller body.  It is proposed according to the invention to arrange within the clothing sleeve, between the radial surfaces of the roller body and of the clamping ring, a resilient element which can be so radially deformed, subject to an axially applied pressure that it frictionally connects the clothing sleeve to the roller body.  As a consequence of the elasticity of the resilient element, the clamping ring can be adjusted to a varying extent relative to the roller carrier, without the frictional connection between the clothing ring and the roller body being thereby impaired.

Abstract: DRIVE SYSTEM FOR  SILO UNLOADER     abstract of The Disclosure A drive system is provided for a silo unloader, in which a generally radially disposed auger at the bottom of a silo, both rotates about its own axis, and sweeps across the bottom of the silo floor.  A sweeping movement is provided by a hydraulic drive.  The rotation of the auger about its own axis is provided by an electric motor drive that traverses a silage dischargeway disposed at the general center of the silo, and that drives the auger from its radial inner end.          A protective covering is provided for part of a drive chain that connects an electric motor drive disposed outside the dischargeway with a  portion of the drive train located inside the dischargeway.  The electric motor drive is mounted for responding to a certain level of resistance to the auger turning on its own axis, that is engendered by silage contact, whereby the motor will pivot on its mount in reactive response to the motor torque developed in driving the auger in rotation on its own axis, with the pivotal movement of the motor being operationally connected to the hydraulic drive that effects the sweeping movement of the auger, to discontinue the provision of hydraulic fluid to the sweeping-motion-drive, until silage resistance is reduced.

Abstract: ABSTRACT OF THE DISCLOSURE            A process is described for the recovery of gallium from scrap materials in which the gallium occurs as gallium compounds containing at least one element selected from the group consisting of aluminum, antimony, arsenic and phosphorus.          The process comprises the steps of leaching said gallium compounds with an oxidizing agent selected from nitric acid and a combination of nitric acid and hydrogen peroxide to form a gallium-containing leach solution, forming a gallate solution from said gallium-containing solution, and recovering gallium from said gallate solution. The leach solution can be treated with a calcium compound chosen from the group consisting of lime and calcium hydroxide for precipitation of calcium arsenate and calcium phosphate.  An alkaline material such as sodium hydroxide may then be added to said leach solution in an amount sufficient to raise the pH to a value of at least 11 to form gallate solution.  Gallium metal preferably is recovered from said gallate solution by electrolysis.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for the high speed labeling of objects includ-ing fruits and the like in which the object is brought to a labeling station by an endless conveyor. The labels are re-leasably mounted on a carrier tape which is stored on a supply reel. The tape is pulled from the supply reel by a knurled roller which impresses a pattern on the outer surface of each label in order to allow it to more readily conform to non-planar surface portions of the object to be labeled. A feed storage loop is formed in the tape by an oscillatable tension regulating arm which controls actuation and deactuation of the knurled roller, dependent upon the position of the arm. The tape then forms an indexing segment which passes through a transfer station, and as each label centers an indexing block in the transfer station, its presence is sensed by suitable label detecting means. Indexing movement of the tape through the indexing block is initiated by object detecting means lo-cated in a predetermined position relative to the conveyor to sense the presence of an object thereon to be labeled. When the object detecting means is actuated by the presence of the object, the tape is indexed, i.e., moved forward and around a sharp bend to strip a detected label from the tape and cause it to be located in a label holding frame. As this occurs, a label transfer wheel is rotated past the label holding frame, and a suction cup that moves in timed relation with the detected object on the conveyor, passes closely adjacent to the label. At this point, a vacuum is applied to the suction cup, which causes it to grip the imprinted surface of the la-bel and carry it from the holding frame as the transfer wheel rotates. The timed movement of the suction cup, and the in-dicated object on the conveyor causes the two to come to-gether with the label to be pressed against a surface of the object, at which time the vacuum is released. Substantially simultaneously, a thin lip of the suction cup is deformed by reaction to pressing against the object, thereby connecting the cup interior with the atmosphere and insuring release of the label from the cup. After the labels have been removed from the tape, the tape passes into a take-up storage loop formed by a second oscillatable tension regulating arm which controls the intermittent actuation of a motor driven take-up reel.
