A strip of curtain web material is stitched to the curtain webs on one side of the slit for covering it when the door opening is closed. Hook and loop fastening tape is located on both sides of the slit, one piece of the tape being stitched to the strip and another complementary piece being stitched to the curtain webs to the other side of the slit.

Abstract: A fiber-reinforced polymeric composite structure having chemically active thermoset particles positioned in an interlaminar region between adjacent layers of reinforcement fibers and method of making the same. Upon curing of the composite structure, the chemically active functional groups on the thermoset particles form covalent bonds with the matrix resin surrounding the particles. In one embodiment, the particles are formed of a partially cured thermoset polymer with a degree of cure of less than 100%. In another embodiment, the particles are derived from a thermosettable resin composition, wherein the stoichiometry is such that there is a deficiency or an excess in the amount of curing agent that is necessary for reacting with 100% of the thermoset resin component. In some embodiments, the composition of the chemically active thermoset particles is the same or substantially the same as that of the matrix resin of the composite structure.

Abstract: A vibratory conveyor system includes two or more product transfer pans bearing lengthwise channels along which products travel, each pan being linked to a respective shaker base via respective spring arms. Successive product transfer pans each have one or more of (1) greater vibration distance oriented along the direction of product travel, (2) greater vibrational frequency/speed, and/or (2) lesser spring arm angle with respect to vertical, than the prior product transfer pan(s). These features assist with obtaining a high degree of uniform product alignment, with products being aligned lengthwise within the channels of the pans, even where products are non-rigid and malleable/reshapeable (for example, for meat cutlets and fish fillets).

Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for selective requests for authentication for voice-based launching of applications. Example methods may include receiving first audio data representing an utterance, determining that the device is in a first operating mode when the audio data was received, determining that the device is in a locked state when the audio data is received, and receiving, from a remote system, a command to display information based at least on part on the audio data. Certain methods may include receiving an indication that the utterance was spoken by a user authorized to access the information while in the first operating mode and the locked state, and causing presentation of the information by the device.

Abstract: A cutting edge system for a snowplow is described. The system includes a backing plate coupled to a moldboard of the snowplow and cutting edge segments mounted to a front of the backing plate. Each cutting edge segment includes a blade segment slidably mounted to the backing plate. Each blade segment has a lower portion, an upper portion having an uppermost edge, and two upwardly extending lobes that define an intermediate portion therebetween. The two lobes each have a slot having a central slot region to receive a fastener and an upper slot region extending between the central slot region and an opening in an upper edge of the lobe. Each cutting edge segment also includes a compression member retained between the uppermost edge of the intermediate portion and an engaging surface of the backing plate to absorb upward movement of the blade segment when the cutting edge engages the ground.

Abstract: Surface-treated polymeric particles which are dispersible in water or an aqueous solution without the aid of any surfactant. Surface treatment of hydrophobic polymeric particles is carried out to increase the surface energy and to render the surfaces of the particles hydrophilic, thereby eliminating the need for a surfactant to disperse the polymeric particles in water or an aqueous solution. As such, a surfactantless slurry can be formed from the surface-treated particles for the fabrication of fiber-reinforced thermoplastic composite structures.

Abstract: Displaying weather-based information for a flight path is disclosed. A data processing system receives a flight path and retrieves weather-related raster-based forecast data along the flight path. The data processing system then generates a vertical profile for the flight path for all altitudes along the flight path and all flight times along the flight path. The weather-related raster-based forecast data is then converted by the system into polygonal bands that are superimposed by the data processing system onto the vertical profile, resulting in a modified vertical profile. The modified vertical profile is then displayed by the data processing system with a selector in a graphical user interface (GUI) for selecting a flight time of the flight times along the flight path.
