US11421391B2	Snow plow blade assembly with angled top shield A snow plow blade assembly allows substantially rigid blades to shift in response to surfaces and obstacles without placing undue stress on the blade assembly as a whole. The assembly includes a flexible bushing that is received in a bushing hole of a blade, the bushing further having at least one bushing hole to receive at least one stem. The blade is disposed between first and second plates that cooperate with the stem and a fastener to removably secure all of the elements together. A kit contains replacement blades and bushings, a flexible bushing or variable density, a wear block assembly on the blade trailing edge, a protuberance on the bushing that is received in one of the plates and a bushing hole formed as two connected lobes for receiving a like shaped bushing.
US11421389B2	Variable height mold A slipform paving machine includes an offset mold, including a mold frame, a form insert, a form insert actuator and a form insert sensor. A controller receives a signal from an external reference sensor and controls a position of the form insert actuator to control the height of the form insert relative to the mold frame and thereby control a height of at least a portion of a molded structure relative to a ground surface at least in part in response to the signal from the external reference sensor.
US11421386B2	Inner liner for a cigarette A moisture-retaining, quality-preserving and aroma-keeping vacuum aluminum-plated inner liner for cigarettes and method of making the inner liner, the inner liner including a raw paper layer, an upper surface of the raw paper layer being provided with a hot melt sealing layer, a water-based sealing layer, a vacuum aluminum-plated layer, and a water-based protective layer, where a lower surface of the raw paper layer is provided with a moisture returning layer and the inner liner further includes a moisture-retaining and aroma-keeping layer disposed on the upper surface or the lower surface of the raw paper layer.
US11421384B2	Soft textured tissue Provided are tissue webs and products that have a modest degree of surface texture, but are still soft. In certain instances the tissue products and webs may also have good sheet bulk and low stiffness. For example, the tissue products may have good softness, such as a TS7 value (measured using the EMTEC Tissue Softness Analyzer) less than 11.0, and a textured surface, such as an R2 value from about 11,000 to about 20,000 (measured using an OpTiSurf tester). The foregoing tissue products may have a sheet bulk greater than about 8.0 cc/g and a Stiffness Index less than about 15.0. In certain instances the tissue product and webs may be through-air dried and may be either creped or uncreped.
US11421381B2	Artificial leather and method of manufacturing the same The present invention relates to artificial leather and a method of manufacturing the same. More particularly, the present invention relates to artificial leather for automobile seat covers, the artificial leather having a texture similar to that of natural leather, having a soft feel like natural leather, and having excellent peel strength and a method of manufacturing the artificial leather.
US11421373B2	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.
US11421367B2	Laundry processing apparatus An apparatus comprising: a washing machine, a drying machine disposed on the washing machine, and a control panel. The control panel including a first user interface configured to control the washing machine, a second user interface configured to control the drying machine, a first start/pause button configured to receive an input for starting or pausing an operating of the washing machine, a second user interface configured to receive an input for controlling the drying machine, and a display configured to display operation information of the washing machine and operation information of the drying machine. The apparatus configured to control an operation of the drying machine in response to an input received through the second start/pause button while operation information of the washing machine is displayed on the display.
US11421362B2	Needling loom with elliptical type movement, table for such a needling loom and manufacturing method of such a table Needle machine comprising at least one needle plate, from which projects an array of needles, means for imparting an elliptical, reciprocating motion to the needles and at least one support table drilled with an array of through holes, or which it is intended to pass in a direction MD, being supported on it, a fabric or web of fibres to be consolidated by needling, the each executing an elliptical, reciprocating motion in the respective through holes, each having an upper respective opening on the fabric support side, a lower respective opening on the opposite side and an inner sidewall extending between the two upper and lower openings, characterised in that each hole is machined so that there is a longitudinal section with a greater dimension MD in which the upper respective opening of the hole has a greater dimension in the direction MD and, in this longitudinal section of greater dimension MD, the inner sidewall of the hole is defined, at least in its upper region, by two left and right lines inclined to the vertical and converging downwards, the angles of inclination of the two lines to the vertical being of opposite sign and in particular each having an absolute value of between 2 and 30° respectively, in particular having the same absolute value.
