| 20100187727 | METHOD OF VOID FREE FOR MOLDING PRODUCT - A method of removing voids from a molded product is disclosed, in which a main mold, is connected with an auxiliary mold, and molten material in the auxiliary mold moves toward the main mold by adjusting a cooling time between the main mold and the auxiliary mold, thereby preventing voids from occurring in the molded product having a large thickness, preventing sink marks from occurring. The method includes the steps of: preparing a main mold and an auxiliary mold connected with the main mold; introducing molten resin into the auxiliary mold and the main mold; and retarding cooling of the auxiliary mold such that negative pressure in the auxiliary mold is different from that in the main mold due to a cooling time difference and a temperature difference. The molten resin in the auxiliary mold moves toward the main mold, and then is filled in the main mold during cooling. | 07-29-2010 |
| 20110001267 | MACHINE FOR INJECTING A HEAT CURABLE MATERIAL, IN PARTICULAR FOR RUBBER VULCANISATION, AND CORRESPONDING METHOD FOR ACHIEVING SAME - This machine includes means for plasticizing the material and injection means suitable for injecting the material in the fluid state into a flow channel ( | 01-06-2011 |
| 20110147996 | SELF SHORTENING FASTENER - Disclosed is a fastener that can be mounted to a bone of a patient and can foreshorten and swell of a desired period of time. The fastener can include a head portion and a body portion extending from the head portion. At least one of the head portion and the body portion has a first width that changes to a second width greater than the first width and collectively the head portion and the body portion have a first length that changes to a second length shorter than the first length upon the head portion and the body portion being exposed to a temperature below a glass transition temperature of a polymeric material forming the head portion and the body portion. | 06-23-2011 |
| 20120086152 | METHODS AND APPARATUS FOR FORMING A COMPOSITE COMPONENT - A mould for a composite component having a fillet joint, the mould including a mould body having a cavity within which the component is formed, and an insert mating with the mould body and including a forming surface against which, in use, the fillet of the component fillet joint is formed. The insert may be thermally insulating and highly rigid. A method of forming a composite component having a fillet joint using a mould, the method including forcing a surface of the fillet region of the component to adopt a non constant radius of curvature while the component is inside the mould during the cure process is also provided. Additionally, a method of forming a composite component having a fillet joint that is defined between first and second legs the method including placing the legs of the component in bending during cure of the component is described. | 04-12-2012 |
| 20120267828 | ZONE CONTROL OF TOOL TEMPERATURE - A tool system for moulding an article is provided which comprising a tool ( | 10-25-2012 |
| 20120299218 | COMPOSITE ACTIVE MOLDS AND METHODS OF MAKING ARTICLES OF SEMICONDUCTING MATERIAL - The disclosure relates to a substrate mold comprising a shell material having an external surface configured to engage with molten semiconducting material, and an internal surface configured as a thermal transfer surface to transfer heat therethrough, and a core defined within the shell material and configured to remove heat from the shell material through the thermal transfer surface of the shell material. The substrate mold is configured to be immersed into the molten semiconducting material, and the external surface of the shell material is configured to have solidified molten semiconducting material formed thereon. | 11-29-2012 |
| 20130161872 | Preservation of the Appearance of Pre-Printed Graphics on Hot Stretched Film - The present disclosure is concerned with improving the appearance of graphics printed on a flexible polymer film which is subsequently heated to a forming temperature and then drawn into a mold to form a cavity adapted for the packaging of an item, typically a food item. The improvement is effected by reducing the heat transfer to the portions of the film carrying the graphics thereby reducing the formability of these portions so that they stretch less than the rest of the film which is drawn into the mold. Typically the film is heated by contact with a heated platen. In such cases the reduced heat transfer can be effected by having zones of a cooler temperature which are adapted to be in registry with the portions of the film carrying the graphics or by covering the portions of the heated platen in registry with these graphics with an insulating material such as Teflon tape. The mouth of the cavity can then be closed by sealing to another flexible polymeric film. If the films used are heat shrinkable, the sealed package can be subjected to thermal conditions which cause it to shrink about the packaged item. | 06-27-2013 |
| 20130241111 | Golf Ball Core And Method Of Making A Golf Ball Core - A method and system for making a golf ball core is disclosed. The method may generally include forming a golf ball core out of a raw core material. The golf ball core may be rapidly heated to begin curing (or vulcanizing) from the outermost surface toward the center of the golf ball core. Before curing the entire golf ball core, the golf ball core may be quenched to stop the curing process. As a result, the golf ball core may include an outer cured zone and an inner uncured zone. In this state, the golf ball core may be incorporated into a finished golf ball to be sold to consumers. Following a set of instructions provided with the golf ball, the consumer may heat the golf ball to customize the properties of the golf ball core, and, thus, the characteristics of the golf ball. | 09-19-2013 |

| 20140097556 | METHOD FOR FABRICATION OF STRUCTURES USED IN CONSTRUCTION OF TOWER BASE SUPPORTS - Disclosed are apparatus and corresponding methodologies for providing a base support, such as including concrete, and used such as for a wind-driven generator. Precast concrete cylinders are stacked in place upon a platform that may be partially precast and partially cast in place during assembly and supported, in certain embodiments, by plural concrete legs, the other ends of which are supported on a unitary or subdivided concrete foundation. In other embodiments, the platform may be supported by ribbed concrete panels. The concrete cylinders are glued together using an epoxy and then secured by an internal vertical post tension system extending from the platform to the upper most cylinder. Methodologies and apparatus for fabrication of concrete structure used in constructing the base support are also disclosed, with a focus on staves and various ring piece constructions. | 04-10-2014 |
