Patent number: 9457600Abstract: A conveyance device including an upstream roller that supplies a sheet medium to be processed to a conveyance path; a downstream roller that conveys the supplied medium to a processing position; and a control unit that, in order to convey the sheet medium at a constant speed, controls driving the upstream roller and the downstream roller using the constant speed as a target speed. The control unit changes the target speed of the upstream roller to eliminate a conveyance difference, which is the difference between the length of media conveyed by the upstream roller and the length of media conveyed by the downstream roller from the start of the conveyance operation, based on the conveyance difference in each conveyance operation.Type: GrantFiled: June 7, 2012Date of Patent: October 4, 2016Assignee: Seiko Epson CorporationInventor: Norio Horaguchi

Patent number: 9394977Abstract: A tensioner is disclosed that may be part of a power system where the tensioner provides tension to an endless power transmitting element such as a belt, chain, or other continuous loop. The tensioner has an arm that is rotatable about a first axis and includes an arm arbor having a window therethrough, a bushing having a protrusion and being positioned adjacent the arm arbor with the protrusion received in the arm arbor's window, and a spring coupled to the arm urging the arm to rotate about the first axis into tensioning engagement with a power transmitting element. The spring is positioned where it can radially expand into contact with the protrusion of the bushing as the arm is rotated in a direction opposite the direction of tensioning engagement such that the bushing is urged radially outward relative to the arm arbor to provide frictional damping.Type: GrantFiled: March 15, 2013Date of Patent: July 19, 2016Assignee: DAYCO IP HOLDINGS, LLCInventors: Kevin Gerard Dutil, Anthony Eugene Lannutti

Patent number: 9377090Abstract: A tensioner assembly that includes a base, an arm, an opening spring (i.e., a torsion spring that opens or radially expands with increasing torque applied thereto), a spring reaction member, and a pivot bushing. The tensioner assembly is configured to orient various loads in predetermined directions. For example, a spring load can be oriented to counteract a hub load to reduce a bushing load that acts on the pivot bushing. As another example, a spring reaction force exerted by the spring reaction member can be employed by a damping mechanism to generate a grounding force that is parallel to the spring reaction force and is directed to intersect an axis about which the arm pivots relative to the base. A tensioner assembly having improved assembly characteristics is also provided.Type: GrantFiled: September 30, 2009Date of Patent: June 28, 2016Assignee: Litens Automotive PartnershipInventors: Wei Ma, Gerald J.

Patent number: 9328805Abstract: A chain-tensioning device comprises at least one main chain-tensioning sprocket wheel on which a chain engages, a main spring that urges a shaft of the main chain-tensioning sprocket wheel in a direction of tensioning of the chain, and an auxiliary cam element that engages a cam-follower element operatively connected to the shaft of the main chain-tensioning sprocket wheel so as to tend to push this shaft in the tensioning direction under the action of auxiliary elastic means. The auxiliary cam element automatically recovers any play that is generated owing to wear of the chain and prevents a movement of the chain-tensioning sprocket wheel in a direction opposite to the tensioning direction. In a variant, two main chain-tensioning sprocket wheels are provided, each having a respective auxiliary cam element. The two auxiliary cam elements may form part of a single pivoted lever.Type: GrantFiled: November 14, 2013Date of Patent: May 3, 2016Assignee: Comau S.p.A.Inventor: Gianpiero Gromme

Patent number: 9303813Abstract: A method, device, and nozzle for dispensing cooled lubricant is provided. Lubricant is supplied to the nozzle through an inner lubricant tube. Cooled compressed gas is also supplied to the nozzle through a conduit which surrounds the inner lubricant tube. Cooled compressed gas from the conduit is introduced into a nozzle gas bore in the nozzle and lubricant is introduced into a nozzle lubricant bore in the nozzle. The cooled compressed gas and the lubricant are mixed at a junction between these bores, such that the lubricant is siphoned into the junction by the cooled compressed gas. The mixture of cooled compressed gas and lubricant are then dispensed from an aperture in the nozzle, preferably as a fine atomized mist of cooled lubricant.Type: GrantFiled: July 22, 2013Date of Patent: April 5, 2016Assignee: Nex Flow Air Products Corp.Inventor: Leslie Frank Rapchak

Patent number: 9303814Abstract: A system for automatically delivering lubricant to at least one bearing (16) has a lubricant pump (1) feeding lubricant under pressure through a supply line (3) to an injector (4). The injector, driven by the lubricant, sends a measured amount of lubricant down feed line (14) to bearing (16). A pressurizing valve (15) maintains injection pressure in the feed line (14) enabling any failure of supply to be detected as a pressure drop at pressure switch (2). Preferred features include the incorporation of a second pressurizing valve (12) at the injector end of the feed line (14), a blocked-line vent valve (13) to enable detection of a blocked or crushed feed line, and check valves (10) and (11). The injector (4) is preferably configured to produce a higher pressure at the outlet than the inlet, and various versions of this intensifying injector are described and claimed.Type: GrantFiled: August 27, 2010Date of Patent: April 5, 2016Assignee: BOB IFIELD HOLDINGS PTY LTDInventors: Benjamin Ifield, Robert William Ifield, Craig Alan Ifield
