Abstract: Aspects include receiving a document and classifying at least a subset of the document as having a first type of data. Features are extracted from the document. The extracting includes initiating processing of the at least a subset of the document by a first processing engine that was previously trained to extract features from the first type of data. The extracting also includes initiating processing of a remaining portion of the document not included in the at least a subset of the document by a second processing engine that was previously trained to extract features from a second type of data. The first type of data is different than the second type of data. Features are received from one or both of the first processing engine and the second processing engine. The received features are stored as features of the document.

Abstract: A water resistant scale damper has a damper sleeve with an interior passage, an open top, and an open bottom. A piston is received in and axially slidable along the interior passage and has a top surface, an underside, and a piston rod extending from the underside toward the open bottom. A top cap is fitted over the open top of the sleeve and an air chamber is created between the top cap and the top surface of the piston. An air passage is formed through the top cap to permit air to enter and exit the air chamber. A portion of the top cap can create an elongate, non-linear air channel between the air passage and a port remote from the air passage and formed through the top cap. A bottom cap can also be fitted over the open bottom of the sleeve. The bottom cap has an annular flange that extends radially inward from a skirt of the bottom cap. The flange is funnel-shaped so as to direct liquid from beneath the underside of the piston toward a central opening in the flange.

Abstract: A pair of the hair cutting scissors (10) includes a finger loop (20), preferably the one for the thumb, which has a finger loop part (32) that can be selectively interconnected with a fixed finger loop part (22) to vary the finger loop area.

Abstract: An electric propulsion system for a wheeled vehicle has a generator and motor connected to a drive shaft and an electrical system for charging a battery during all conditions of power transfer from the wheels of the vehicle to the generator to minimize energy required for propulsion. A variable speed power coupling unit connecting the motor to the drive shaft has sprockets revolving about a belt connected sun sprocket with speed control effected by varying the rate of satellite sprocket rotation.

Abstract: An epoxy resin composition curable to a hard impermeable solid which contains a liquid aromatic diluent having the general formula:C.sub.6 (R.sub.1).sub.6wherein R.sub.1 is hydrogen; a straight or branched chain alkyl radical; a cycloparaffin radical or a mixture thereof; wherein the alkyl and cycloparaffin radicals have within the range of about 1 to 10 carbon atoms; and further wherein at least one R.sub.1 group is said alkyl or cycloparaffin radical.
