Patent number: 11097472Abstract: At least one agent distributor may be to selectively deliver coalescing agent onto portions of a layer of build material at a first density and at a second density lower than the first density. A controller may be to control the at least one agent distributor to selectively deliver the coalescing agent at the first and second densities onto respective first and second portions of the layer in respective first and second patterns derived from data representing the three-dimensional object to be generated, so that when energy is applied to the layer the build material may coalesce and solidify to form a slice of the three-dimensional object in accordance with the first pattern. The second portion may be in proximity to a boundary of the first portion. Presence of the coalescing agent in the second portion may be to prevent at least some heat from flowing away from the first portion when the energy is applied.Type: GrantFiled: July 30, 2019Date of Patent: August 24, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Bernardo A.

Patent number: 6162555Abstract: A novel fuel particle feeding mechanism that significantly improves operation of a refuelable electrochemical power source is provided. One embodiment of the mechanism provides an input of electrolyte and electrochemically active particles into one or more electrochemical cells through a feed tube. The feed tube has several embodiments that improve the flow of electrolyte and particles, and the even and complete settling of particles into individual cell cavities. Each cell cavity is completely filled, evenly and without clogging when open, and fluid communication between cell cavities is completely cut off when closed, to prevent short-circuiting of the power source during discharge or standby. Means are provided to prevent clogging of the feed tube with fuel particles, to promote complete filling of the cell cavities with fuel, and to prevent fuel particles from prematurely flowing out of the cell cavities. A method of operation is also described.Type: GrantFiled: July 15, 1999Date of Patent: December 19, 2000Assignee: Metallic Power, Inc.Inventors: Bernardo A. Gutierrez, Jeffrey A. Colborn, Stuart I.
