Abstract: A firearm slide includes a mounting plate that is removably connected to a planar mounting surface of the firearm slide. A rear sight is removably attached to the mounting plate so that different types or styles of rear sights may be used with the firearm. Upon removing the mounting plate itself, various mounting features defined in the planar mounting surface of the slide are exposed. These mounting features can be used to attach any of a variety of accessories (whether a telescopic sight, a red dot sight, a light, or other accessory) directly to the exposed planar mounting surface of the slide.

Additionally, the invention features a seed treatment composition that includes a) an agrochemical; b) a pH-dependent film-forming polymer; and c) a seed coating agent.

Abstract: A method of manufacturing a machining tool in which an insert holder comprises a first surface, a second surface opposite the first surface, and a first insert tip slot extending between the first surface and the second surface. The first insert tip slot is configured so as to be compressed and densified to support a first insert tip. The insert holder further includes elevated projections extending from the first and second surfaces proximate the first insert tip slot.

Abstract: A heat sink is disclosed comprising a metallic pin extending between a proximal end and a distal end. A lower pin stud is positioned adjacent to the proximal end. An upper pin stud is positioned adjacent to the distal end. A base flange is interposed between the lower pin stud and the upper pin stud and defines a lower base surface and an upper base surface. The lower pin stud engages a source aperture and the lower base surface engages a source surface. A composite pitch fiber encapsulates the upper pin stud and the upper base surface. The metallic pin and the composite pitch fiber transfer the thermal energy from the lower pin stud and the lower base surface, through the upper pin stud and through the composite pitch fiber for dissipating the thermal energy from the source.

Abstract: A method of preparing an iron-implanted semiconductor wafer for use in surface photovoltage iron mapping and other evaluation techniques. A semiconductor wafer is implanted with iron through the at least two different regions of the front surface of the semiconductor at different iron implantation densities, and the iron-implanted semiconductor wafer is annealed at a temperature and duration sufficient to diffuse implanted iron into the bulk region of the semiconductor wafer.

Abstract: A latch for coupling a first object to a second object is disclosed comprises a primary block coupled to the first object. A locking cam is rotatably coupled to the primary block. A cam track having a sloped surface is in the locking cam. A locking stem slideably engages the primary block and traverses the locking cam. A cam pin is coupled to the locking stem. The cam pin slidably engages the sloped surface for displacing the locking stem between an extended position and a retracted position. A stem head is coupled to the cam pin. A secondary block is coupled to the second object. A cam channel is in the secondary block for receiving the locking stem. A head receiver is in the secondary block for engaging the stem head. The extended position defines an unlocked position and the retracted position defines a locked position.

Abstract: Various embodiments of a rotatable awning with illumination are provided. The awning includes an axial groove wherein a plurality of luminaires are located for lighting of an area below and around an extended awning. The awning includes an electromechanical rotatable conductor which provides electrical contact between a fixed portion of the awning assembly and the rotating awning roller tube. This allows for flow through of electricity or current to the luminaires and/or the awning motor internally through the roller tube.

Abstract: Various embodiments of an awning roller assembly is provided. The structure provides an awning roller tube having a first end and a second end with a powered groove extending between the ends, in full or in part. The powered groove includes a plurality of tracks having at least one electrical conductor in each track. An accessory base is provided for connection with a plurality of powered accessories, including but not limited to, lights, fans or audio-video equipment. The accessory base provides electrical connection between the powered groove and the accessory to provide improved function in the outdoor living space beneath and around the awning.

Abstract: A thermally conductive rope includes a plurality of tows of crystalline carbon fiber, a plurality of tows of additional fiber, and at least one of a thermoset and thermoplastic.

Abstract: A power track assembly is provided which may be used with an accessory base (454) therefore. The power track assembly includes a track housing (402) having at least one track (470) with first and second conductors (484, 485). The conductors provide power to the accessory base which may be connected to an accessory (32, 34, 36, 37) requiring power for operation. The accessory base (454) may also be used with power tracks in a roller tube awning assembly (20), a cassette awning assembly (120), or hardware assembly (328).

Abstract: A system and method are presented for learning call analysis. Audio fingerprinting may be employed to identify audio recordings that answer communications. In one embodiment, the system may generate a fingerprint of a candidate audio stream and compare it against known fingerprints within a database. The system may also search for a speech-like signal to determine if the endpoint contains a known audio recording. If a known audio recording is not encountered, a fingerprint may be computed for the contact and the communication routed to a human for handling. An indication may be made as to if the call is indeed an audio recording. The associated information may be saved and used for future identification purposes.

Abstract: In process for the hydrolysis of a methyl acetate with at least one of water and methanol in the presence of at least one Brønsted acid catalyst to produce acetic acid the performance of the catalyst is improved by using a methyl acetate feed in which the total amount of acetaldehyde and 1,1 dimethoxyethane impurities is maintained at 100 pm wt or less calculated as mass equivalents of acetaldehyde.
