US11327145B2	Positioning, navigation, timing, ranging, or beacon transmission system apparatus which utilizes and exploits—relayed, delayed, or virtual timing marker transmissions of GPS, GPS alternative, GNSS, PNT, electronic, optic, acoustic, or similar signals Traditional “low-to-high waveform change” timing markers, in navigation or GPS signals, can be easily naturally or maliciously altered and require unshareable, high-resolution, high-capacity channels, often not government available. Whereas, message text format methods include proven error correction, redundancy, encryption, jam-resistance, concealability, spoof-resistance, multiuser, delayable messaging, channel efficiency, and downstream authentication. Herein, “virtual timing markers” exploit message format strengths and more. Because many navigating platforms also communicate voice, messages, or data, platforms and multiuser messages can simultaneously and unintrusively share the same transmission signal, which reduces onboard hardware, needed channel capacity, radio frequencies, costs, and infrastructure. FAA mandated, airliner collision avoidance broadcasts of their GPS location can unintrusively commingle navigation messages with aforementioned strengths as precise derivative GPS timing markers on existing, prolific broadcasts having 1000× greater power levels. “Relayed transmission pathways” can eliminate cumbersome traditional nanosecond synchronization of navigation transmitters or exploit inclusion of happenstance neighborhood transmitters.

A handle shaft has a vertical engagement portion rotatably engaged within the shaft aperture and an angled extension portion coupled to the engagement portion. A locking pin is coupled to the engagement portion and is selectively engageable with each of the plurality of adjustment apertures of the shaft housing to lock the handle shaft in a straight position, at least one alternative left tilt position, and at least one alternative right tilt position.
US11326313B2	Method for pre-stressing a steel structure, and steel structure pre-stressed using said method According to the method, at least one carbon fibre-reinforced polymer band is joined to the steel structure at the end regions thereof, capable of transferring tensile forces. Subsequently, at least one lifting element (7) disposed between the carbon fibre-reinforced polymer band (4) and the steel girder (3) to be reinforced in a region between these end anchorages (5), is extended substantially perpendicular to the carbon fibre-reinforced polymer band (4). So, a tensile force stress is generated between the end regions of the carbon fibre-reinforced polymer band (4). Then, a steel girder treated in such a manner includes at least one carbon fibre-reinforced polymer band, which is each joined to the steel structure (1) at the end regions thereof, capable of transferring tensile forces. In the region between these end regions, a lifting element (7) is disposed between the carbon fibre-reinforced polymer band (4) and the steel girder (3) to be reinforced, by means of which the carbon fibre-reinforced polymer band (4) is subjected to tensile stress by lifting away from the steel girder (3). The tensile force is transferred to the steel girder (3) via the anchoring elements (5).
US11326311B2	Durable joint seal system with flexibly attached cover plate and rib A system which creates a durable seal between adjacent horizontal panels, including those that may be curved or subject to temperature expansion and contraction or mechanical shear. The durable seal system incorporates a plurality of ribs, a flexible member between the cover plate and the ribs and may incorporate a load transfer plate to provide support to the rib from below, and/or cores of differing compressibilities.
US11326310B2	Concrete and masonry restoration and ornamentation method and apparatus A method and apparatus are provided to rehabilitate and beautify cracked concrete surfaces by adding channels to the surface.
US11326309B2	Paper treatment agent Provided is a paper treatment agent with which improved touch feeling different from smoothness that has been conventionally studied is obtainable when a pressure is applied like nose blowing or the like. A paper treatment agent of the present invention is a paper treatment agent containing (A) a polyhydric alcohol as a main component, the paper treatment agent contains (B) a sucrose fatty acid ester having an acyl group with more than 12 and less than 22 carbon atoms and an HLB of 11 or more and (C) an ionic surfactant, and it is characterized in that a mass ratio (C/B) of the component (C) to the component (B) is 0.65 to 24. According to the paper treatment agent of the present invention, when a pressure is applied to treated paper like nose blowing or the like, slick texture that is specific and distinctive smoothness which is non-conventional is obtainable.
US11326303B2	Modified cellulosic compositions having increased hydrophobicity and processes for their production The disclosure provides a composition comprising a modified cellulosic surface having aliphatic fatty acid molecules and amine-silica particles that are covalently bonded to cellulose fibers of the cellulosic surface. Also disclosed is a composition comprising a modified cellulosic surface including low surface energy molecules and amine functionalized nanotubes decorated with silica nanoparticles that are covalently bonded to cellulose fibers of the cellulosic surface. Also disclosed is a process for increasing hydrophobicity of a cellulosic surface. Also disclosed is a process for increasing hydrophobicity and surface roughness of a cellulosic surface. Also disclosed are products comprising the compositions and modified cellulosic surfaces of the present invention.
US11326300B2	Clothes treating apparatus having drying function A clothes treating apparatus having a drying function includes: a cabinet; a drum provided within the cabinet; a heat-exchanger heat-exchanged with air exhausted from the drum; a lint filter disposed on an upstream side of the heat-exchanger with respect to flow of air exhausted from the drum to collect lint in the air; a spray tube spraying water to the lint filter to separate lint collected in the lint filter from the lint filter; and a lint collecting part at least partially provided below the lint filter or below the heat-exchanger to collect falling lint. Lint in condensate water may be collected, and thus, generation of a bad influence when condensate water is re-used may be suppressed. Also, contact between lint in drying air and the heat-exchanger may be restrained.
US11326296B2	Washing machine A washing machine is provided. The washing machine includes a water tub configured to be disposed in a cabinet and to store wash water, a rotating tub configured to be rotatably installed in the water tub and to include an opening formed in an upper end portion thereof, and a driver configured to be connected to the rotating tub and to rotate the rotating tub, wherein a deviation preventer configured to prevent wash water in the rotating tub from being deviated to one side during rotation of the rotating tub is formed at an upper end portion of the rotating tub.
US11326295B2	Basket for a laundry treating appliance A laundry treating appliance includes a tub defining a tub interior and a basket rotatably mounted within the tub interior. The basket can include an upper basket portion defining a basket interior, as well as a lower base portion coupled to the upper basket portion and including at least one spoke.
