Patent number: 10189292Abstract: A method for applying a security device (e.g., a micro-optic security thread) to a fibrous web during manufacture is provided. By way of the inventive method, the security device is preferably applied onto the fibrous web at or near a couch roll or similar tool of a paper machine when the fibrous web constitutes a sufficiently consolidated, fully formed wet web. Papers made in accordance with the inventive method, when subjected to the Circulation Simulation Test, showed minimal damage at the paper/security device interface. Moreover, the surface-applied security devices showed acceptable levels of intaglio ink adhesion, and the papers had higher cross-direction (CD) tensile strength and much less show-through on opposing sides thereof.Type: GrantFiled: February 11, 2016Date of Patent: January 29, 2019Assignee: Crane & Co., Inc.Inventors: Giles D. Prett, Manish Jain, Kraig M. Brigham

Patent number: 10150657Abstract: The crane includes a swing brake device installed between a hydraulic motor and a control valve and having a flow restrictor; a first backpressure detector detecting a motor backpressure between the flow restrictor and one of ports of the hydraulic motor; a second backpressure detector detecting a motor backpressure between the flow restrictor and the other port of the hydraulic motor; and a control device. The control device has an external-force direction estimation unit that estimates a swing direction of an upperstructure under an external force acting on the upperstructure on the basis of a motor backpressure detected by the first backpuressure detector and a motor backpressure detected by the second backpressure during an operating state of the swing brake device. The control device has a notification control unit that causes the notification device to provide notification of the estimated swing direction of the upperstructure.Type: GrantFiled: March 2, 2017Date of Patent: December 11, 2018Assignee: Hitachi Sumitomo Heavy Industries Construction Crane Co., Ltd.Inventor: Kota Miyoshi

Publication number: 20180104976Abstract: A sheet material having a security device applied over a paper machine made or ‘soft-edged’ through-hole and a method for preparing such a sheet material is provided. By way of the inventive method, the through-hole(s) is formed in a forming fibrous web before it becomes sufficiently consolidated and then the security device is applied onto the fibrous web and preferably over the through-hole(s) at or near a couch roll or similar tool of a paper machine when the fibrous web constitutes a sufficiently consolidated, fully formed wet web. Applying the security device and then further consolidating the region underlying the device at this stage of paper manufacture when the fibers would not be displaced, greatly reduces (if not eliminates) the possibility of the through-hole(s) becoming occluded or blocked. Moreover, papers made in accordance with the inventive method, when subjected to the Circulation Simulation Test, showed minimal damage at the paper/security device interface.Type: ApplicationFiled: December 14, 2017Publication date: April 19, 2018Applicant: Crane & Co., Inc.Inventors: Giles D. Prett, Manish Jain, Kraig M. Brigham

Patent number: 9944502Abstract: A cylinder retraction system causes a crawler side frame hoisting hydraulic cylinder, swingably suspended on a ventral surface side of a lower boom, to swing between a retracted attitude, in which the hydraulic cylinder is set along a ventral surface of the lower boom, and an operating attitude, in which the hydraulic cylinder is oriented along a vertical direction. As the rod of the hydraulic cylinder, currently having the operating attitude, is contracted by a predetermined extent, the rod front end of the hydraulic cylinder is guided by the guiding portion until the hydraulic cylinder takes on the retracted attitude. As the hydraulic cylinder, currently having the retracted attitude, is extended by a predetermined extent, engagement between the rod front end of the hydraulic cylinder and the guiding portion is released so as to allow the hydraulic cylinder to take on the operating attitude.Type: GrantFiled: November 25, 2016Date of Patent: April 17, 2018Assignee: Hitachi Sumitomo Heavy Industries Construction Crane Co., Ltd.Inventor: Tomoaki Yamashita

Patent number: 9708773Abstract: The invention generally relates to a security sheet or document having one or more enhanced watermarks. In one exemplary embodiment, the inventive security sheet or document is a single-ply paper that is made up of a paper layer including one or more watermarks, and a micro-optic security device (e.g., a patch or thread) that at least partially covers an upper or face portion of the watermark(s). The overlying patch or thread increases the durability of the watermark(s), thereby allowing for the watermark(s) as well as reduced fiber density areas therein to be made larger, and further allowing for the reduced fiber density areas to be made thinner. In a preferred embodiment, the micro-optic security device projects one or more synthetic images that coordinate or link in with the watermark design(s). In a more preferred embodiment, the micro-optic security device offers a machine detectable/readable feature in the form of enhanced IR-brightness, especially when measured in transmission.Type: GrantFiled: December 2, 2014Date of Patent: July 18, 2017Assignees: Crane & Co., Inc., Crane Security Technologies, Inc., Crane ABInventors: William Blake, Jeffrey Boody, Kraig M.
