Sharp p-bounds for maximal operators on finite graphs. (arXiv:2005.03146v1 [math.CA])

Let $G=(V,E)$ be a finite graph and $M_G$ be the centered Hardy-Littlewood maximal operator defined there. We found the optimal value $C_{G,p}$ such that the inequality $$Var_{p}(M_{G}f)le C_{G,p}Var_{p}(f)$$ holds for every every $f:V o mathbb{R},$ where $Var_p$ stands for the $p$-variation, when: (i)$G=K_n$ (complete graph) and $pin [frac{ln(4)}{ln(6)},infty)$ or $G=K_4$ and $pin (0,infty)$;(ii) $G=S_n$(star graph) and $1ge pge frac{1}{2}$; $pin (0,frac{1}{2})$ and $nge C(p)<infty$ or $G=S_3$ and $pin (1,infty).$ We also found the optimal value $L_{G,2}$ such that the inequality $$|M_{G}f|_2le L_{G,2}|f|_2$$ holds for every $f:V o mathbb{R}$, when: (i)$G=K_n$ and $nge 3$;(ii)$G=S_n$ and $nge 3.$

Sharpener, especially for a cosmetic or pharmaceutical pencil

A sharpener for sharpening a pencil, in particular a cosmetic pencil, is especially suitable, when used correctly, for producing a particularly uniform outer jacket edge in the region of the pencil tip. The sharpener includes a sharpener body, in which a pencil guide channel is provided. The pencil guide channel has a circular cone-shaped channel section and opens out in a pencil inlet opening on the outer side of the sharpener body. A paring blade is positioned tangentially to the lateral surface of the channel section. The paring blade serves to pare off a pencil tip, which includes a front lead section and a rear outer jacket section. A shaping tool cuts a shoulder into the pencil tip, the shoulder being set back in relation to a circular cone-shaped enveloping surface of the pencil tip. The shaping tool is arranged relative to the pencil guide channel to insert the shoulder into the transition between the lead section and the outer jacket section of the pencil tip.

Wavy agricultural tillage blade with sharpened edge

A method of making a tillage blade by obtaining a generally circular sheet metal steel disc having an outer peripheral edge. Waves are made in the outer peripheral edge of a circular steel disc in a predetermined pattern while the steel is cold. The outer peripheral edge is then sharpened at a predetermined acute angle with respect to a first plane by grinding. Then the disc is heat treated to make it harder so it will wear longer. If it is desired to have a concave/convex disc, instead of a coulter, then during the heat treating process the disc is deformed so that the sharpened portions of the peripheral edge remain generally in the first plane but a central portion of the disc is disposed at least partially in a second plane which is parallel to but spaced from the first plane.

Sharpening a cutting edge of a tool using a reverse sharpening guide

Apparatus and associated method for sharpening a cutting edge of a tool.

Sharpener for a snow travel member such as a ski or a snowboard

In one aspect, the invention is directed to a sharpener for sharpening a corner edge of a snow travel member, which may be, for example, a ski or a snowboard. The corner edge is between a bottom face and a side face of the snow travel member. The sharpener includes an angle adjustment mechanism to adjust the angle between surfaces on the sharpener that support the bottom face and side face of the snow travel member, in order to accommodate different snow travel members, that may have different angles between their bottom face and their side face. For example, the angle adjustment member may be capable of adjusting the angle between a bottom face orienting surface on the sharpener and a side face orienting surface on the sharpener between a range of angles. The range of angles may be, for example, a range from 85 degrees and 90 degrees.

Adjustable abrasive sharpener

An adjustable manual abrasive sharpener having a pair of sharpening slots formed in a frame with opposing abrasive arms being pivotally mounted in each of the sharpening slots. A rod is mounted on the frame for rotatable motion and for linear motion long its axis of rotation from a position at which the rod is locked against rotation to a depressed position whereby the rod may be rotated. The bottom end portion of the rod includes a pinion gear which engages a pair of gear racks which are mounted for movement laterally relative to the axis of rotation of the rod. The pair of gear racks respectively engage slots formed on the bottom of the abrasive arms in each sharpening slot. Rotation of the rod causes movement of the gear racks to adjust each pair of abrasive arms with respect to each other to vary the sharpening angle of the abrasive elements.

Blade sharpening system for multiple blade shapes

A blade sharpening system using the interior surface of a grinding wheel against which a blade is drawn along its entire length for sharpening. The sharpening system includes a blade holding configuration having multiple hinged arms. A cam operating between two of the hinged arms serves to alter the angle of incidence between the blade and the grinding wheel as the blade is drawn across the grinding wheel. The result is that a wide variety of different blade configurations can be easily accommodated by the sharpening system.

Hand-held sharpener with multiple abrasive rods to sharpen a cutting edge of a tool

A multi-rod hand-held sharpener includes a handle with an outer grip surface for a hand of a user, a first abrasive rod having a first outer abrasive surface with a first abrasiveness level, and a second abrasive rod having a second outer abrasive surface with a second abrasiveness level different from the first abrasiveness level. At least one guide surface extends toward the first sharpening surface at a selected guide angle non-orthogonal to the first sharpening surface. The user contactingly engages a side of the tool against the guide surface and a cutting edge of the tool against the first abrasive surface, and then advances the side of the tool away from the guide surface and the cutting edge against the first abrasive surface while maintaining the tool at the selected guide angle. An optional second guide adjacent the second abrasive surface at a different angle facilitates micro-beveling.
