Publication number: 20240051293Abstract: A continuous inkjet printer (50) has an ink droplet generator (52) and a controller (58) that varies a modulating voltage applied to the ink droplet generator (52) and measures corresponding breakup times of a jet of ink into ink droplets to obtain a portion of a characteristic of breakup time against modulating voltage. The controller (58) obtains a variation range, varies the modulating voltage over the variation range to obtain the portion of the characteristic, calculates a gradient from the portion of the characteristic, compares the gradient with a predetermined gradient and, depending on whether the calculated gradient is less than or greater than the predetermined gradient, generates an adjusted variation range that is displaced in a first sense or a second, opposite sense, respectively, relative to the variation range.Type: ApplicationFiled: December 15, 2021Publication date: February 15, 2024Applicant: DOMINO UK LIMITEDInventors: Richard Thomas Calhoun BRIDGES, Justin CHASE, Stuart Mark WALKINGTON

Publication number: 20230158829Abstract: Implementations disclosed and claimed herein provide a wheel cover system. In one implementation, an inward force exerted against a wheel cover of the wheel cover assembly in an inward direction towards the hub is received. The inward force overcomes a spring bias of a spring of the receiver and translates the wheel cover assembly in the inward direction. A first rotational force rotating the wheel cover assembly in a first direction is received. The first post guides and engages the first hook, and the second post guides and engages the second hook during rotation. A first positive feedback is generated in response to the inward force and the first rotational force. The wheel cover assembly is releasably locked to the receiver by translating the wheel cover assembly in the outward direction using an outward force generated by the spring bias. The outward force provides a second positive feedback.Type: ApplicationFiled: January 23, 2023Publication date: May 25, 2023Applicant: Moochout LLCInventors: Jonathan E. Fleck, John Thomas Calhoun

Patent number: 11479044Abstract: A print head (10) for a continuous inkjet printer has an ink drop generator (12), an ink supply tube (14) connected to the ink drop generator (12), and a solvent supply tube (16) connected at a first end to the ink drop generator (12) and for connection at a second end to a solvent reservoir. The solvent supply tube (16) is provided with ink flow restriction means (24, 26) for restricting a flow of ink from the ink drop generator (12) into the solvent supply tube (16). The flow restriction means (24, 26) comprise an arrangement (24) of the solvent supply tube (16) such that, for a flow direction reversing portion (26) of the solvent supply tube (16) at the first end of the solvent supply tube (16), a flow of solvent from the second end to the first end of the solvent supply tube (16) flows away from the ink drop generator (12). Also a printer including such a print head and a former for use with such a print head.Type: GrantFiled: July 29, 2019Date of Patent: October 25, 2022Inventors: Richard Thomas Calhoun Bridges, Stuart Mark Walkington

Patent number: 11220103Abstract: A continuous inkjet printer (10, 100) has an ink drop generator (12, 112a, 112b) to generate a stream of ink drops (24), deflection means (14, 16, 18, 20, 114, 115, 116, 118a, 118b, 120) to direct each drop of the stream of ink drops either to a gutter (28) or to one of a plurality of default print positions in a stroke direction (30) on a substrate (26, 126), and input means (22, 122) to receive an indication of an offset. The deflection means, in dependence upon the indication of the offset, direct drops that would otherwise be directed to default print positions to offset print positions on a substrate (26, 126), the offset print positions being displaced in the stroke direction 30 by the offset from the default print positions.Type: GrantFiled: June 27, 2019Date of Patent: January 11, 2022Inventor: Richard Thomas Calhoun Bridges

Patent number: 10906324Abstract: The invention provides a method of adding solvent or make-up fluid into the gutter line of a continuous ink printer. During the addition of solvent, the vacuum level in the gutter line is monitored and maintained at a level sufficient to ensure that vacuum is maintained at the gutter. Vacuum level in the gutter line is preferably controlled by controlling the speed of a variable speed gutter pump. Noise in the gutter line is preferably used as a control over pump speed.Type: GrantFiled: July 13, 2017Date of Patent: February 2, 2021Inventors: Stuart Mark Walkington, Richard Thomas Calhoun Bridges, Colin Jon Partridge, Justin Chase
