Publication number: 20200206873Abstract: A blasting or stripping booth is provided creating a generally downward flow for treatment of fluid and particle flow, which reduces operator exposure to potentially hazardous debris. The booth comprises an enclosure defining an upper region for a workpiece, a lower region, and a separator assembly. In some instances the separator assembly includes individual separator units which are discrete units, each having a generally square or rectangular plan view configuration which are arranged in an array for providing the required process flow capabilities. Further embodiments utilize structures forming the separator which have an elongated trough-like configuration. These embodiments find a particular application in large-scale stripping or blasting booth used in production environments where workpieces may flow through a treatment system in a serial manner. Other suitable applications include batch type processing of parts.Type: ApplicationFiled: July 27, 2018Publication date: July 2, 2020Applicant: GIFFIN, INC.Inventors: ABRAHAM J. SALAZAR, DONALD A.

Publication number: 20200206878Abstract: A handheld skate blade sharpening tool that has an automatically indexing, rotating sharpening stone that matches the concaved profile of the skate blade retained within a two-piece body member. Screws hold the two-piece body member together to keep the round sharpening stone sized to match the desired concave profile. The sharpening stone will remove metal to match the shape of the stone each time the sharpener is moved back and forth along the blade. The sharpening stone has gears on each end of the stone that match the gears inside the two-piece body. As the tool is moved along the skate blade, the sharpening stone will incrementally rotate within the body when the direction is changed in the reciprocating motion by the user's back and for movement.Type: ApplicationFiled: August 19, 2019Publication date: July 2, 2020Applicant: Maintain Your Edge, LLCInventor: Daniel Ray Downen

Publication number: 20200206879Abstract: A pliers (1) has jaw portions (21) incorporating gripping faces for the clamping of the desired workpiece (80), two pivotal handle portions (22) and a sprung toothed strut (40) positioned between the handles (22, 301). A bow shaped resilient portion (304), incorporated within the second arm (20, 300) portion, when the pliers (1) are operated this resilient portion (304) imparts a useful superior sprung pressure upon the clamped workpiece (80) by the gripping face (26, 303) of the jaws (201, 21). The second arm (20, 300) and bend promoting portion are contiguous with each other. The jaws (201, 21) can be usefully locked in the required clamping position upon the workpiece (80) by a toothed sprung strut (40) pivotally attached to the first and second arms (20, 22) and conveniently being locked or unlocked according to the locking switch (500, 50) pivotal within the first arm (20, 300).Type: ApplicationFiled: July 10, 2018Publication date: July 2, 2020Inventor: Nigel Buchanan

Publication number: 20200206881Abstract: A driving tool includes a housing, a follower assembly at an end of the housing, a driving assembly at another end of the housing, and a pressing handle. The driving assembly includes a first driving member, a second driving member, and a one-way rotation structure between the first driving member and the second driving member. The pressing handle is engaged with the first driving member to drive it to rotate. The first driving member drives the second driving member to rotate toward a specific direction via the one-way rotation structure. Thereby, the follower assembly is driven to rotate toward a specific direction.Type: ApplicationFiled: December 27, 2018Publication date: July 2, 2020Inventor: YU-TUNG TAN

Publication number: 20200206882Abstract: A fastener system includes a fastener and a driver, each of which have three alternating lobes and troughs that define the drive surfaces. Each alternating lobes and troughs is defined by an outer radius portion, a drive side transition, an inner transition radius, and a reverse drive portion. The fastener recess and the driver each also have a side wall defined by the outer transition radius that tapers at a taper angle relative to a rotational axis. The fastener side wall may taper at about 60°. The driver side wall may taper at about 60°. Alternatively, the driver side wall may taper at an angle at least 10° less than the taper angle of the recess side wall, such as 42°. The drive side transition defines a drive angle, which may be between 0° and 5°.Type: ApplicationFiled: December 20, 2018Publication date: July 2, 2020Applicant: INFASTECH INTELLECTUAL PROPERTIES PTE.
