Patent number: 7726922Abstract: A quick release support post and associated method are provided to attach a cable to a structure and later move the cable location without the need for many small parts and tools. Thus, cables and wires may be installed in hard-to-reach areas quicker and easier than with conventional clamps because no tools are required and an installer generally does not have to use both hands. Because the quick release support posts and associated method require only a hole in the structure for installation, there is no need for extra materials, and minimal weight is added to the structure during installation or movement. In addition, the quick release support posts and associated method of the present invention create efficient cable management systems because the support posts may be various lengths and cables may be grouped and secured to the support posts together, which makes trouble shooting and later moves much easier.Type: GrantFiled: December 9, 2003Date of Patent: June 1, 2010Assignee: The Boeing CompanyInventor: Kenneth M.

Patent number: 7726962Abstract: An apparatus and method for molding composite material with a selectable uniform predetermined temperature during most of the curing time. The mold apparatus has two cooperating and complementing mold bed assemblies hingedly mounted to each other and movable between two extreme positions, open and closed. A composite inner skin and outer skins sandwich a spacer in between. The spacer member includes interconnecting passages throughout. An outer perforated composite skin member covers the spacer member. A source for pressurized gas is applied to the mold assemblies when in the closed position. A predetermined cooperative temperature is selectably used to uniformly control the curing characteristics of the first and second skin members as the pressurized hot gas or air forced to pass through the outer skin and the spacer member adjacent to the inner skin thereby exposing the form being molded to a uniform temperature gradient.Type: GrantFiled: October 19, 2005Date of Patent: June 1, 2010Inventors: Joseba Aramburu, Sergio Velez

Patent number: 7726963Abstract: Disclosed is a soap making split mold composed of a set of splits 1A and 1B adapted to be assembled together to form a molding cavity 1C. The split 1A has a larger surface area in its recess 11A defining part of the cavity 1C than the other split 1B does in its recess 11B defining the other part of the cavity 1C. The ratio of the surface area of the recess 11A of the split 1A to that of the recess 11B of the split 1B ranges from 52:48 to 66:34. Otherwise, the split 1A has a larger surface roughness Ra in its recess 11A defining part of the cavity than the other split 1B does in its recess 11B defining the other part of the cavity. The difference of the surface roughness Ra between the recess 11A and that of the recess 11B is 0.1 to 30 ?m.Type: GrantFiled: April 1, 2004Date of Patent: June 1, 2010Assignee: Kao CorporationInventors: Takashi Nakano, Shinji Kodama

Patent number: 7726964Abstract: A molding apparatus for patterning a workpiece includes a first support member for supporting the mold, a second support member arranged opposite to the first support member, and a pressing mechanism for pressing the mold and the work together using the support members to pattern the workpiece. In this structure, either the surface of the first support member for supporting the mold or the surface of the second support member for supporting the workpiece is smaller in area than both surfaces of the mold and the workpiece.Type: GrantFiled: August 29, 2008Date of Patent: June 1, 2010Assignee: Canon Kabushiki KaishaInventor: Junichi Seki

Patent number: 7726966Abstract: An exemplary mold unit includes a first mold module and a second mold module adjacent to the first mold module. Each of the first mold module and the second mold module includes a fixed mold and a movable mold capable of moving toward and away from the fixed mold. The fixed and movable molds are configured to form a plurality of shaping chambers therebetween when the fixed and movable molds are in a closed position. The fixed mold defines a main runner having an inner end capable of communicating with the shaping chambers for supplying molten material into the shaping chambers.Type: GrantFiled: December 3, 2008Date of Patent: June 1, 2010Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Hou-Yao Lin, Sheng-Jung Yu
