Inventor: LABRADOR GAUDENCIO A
IPC: F24F1/0059
Filed: 2002-08-12
Abstract: What has been invented is a series of scientific applications of the wideface energy converter device, be it in the form of a wideface solar heat receiver or a wideface fluid impeder device. The wider is the solar heat receiver, the more solar power is available for conversion. The wider is the sail of the boat, the more wind is available to push the boat. Wherefore, the wideface solar trap made up of multi-layer transparent roofs covering a heat insulated box is used to heat up a radiator tubings that contain water.  The multilayer transparent roof, having spaces in between sheets, prevents solar heat from backing out hence the trap becomes hoter and hoter because the inner sheet is not in contact with the cold wind. This solar trap is now used to heat up radiator pipes of compressed air coming from a gas turbine engine and then returned back to the exhaust turbine of same engine. Applying the principle of the wind sail, the turbine blades of the compressor and the turbine blades of the exhaust turbine are made wideface as much as possible to produce maximum impedance against the expanding exhaust hot air and to produce maximum push upon the fresh air being compressed. This wideface fluid impeder is now expanded into an underwater platform from One Acre or much more and attached to floating hotels, large/small boats, and floating sea walls, to prevent oscillation by the surfs.

Title: Scaffolding safety apparatus and method of installation
Inventor: PANACCI DANNY
IPC: E04G5/14
Filed: 2002-08-27
Abstract: A safety apparatus capable of installation around the top level of a scaffolding from one scaffolding level below includes a plurality of support posts and rails. The support posts each have a set of hooks for pivotably attaching rails, and are each capable of attachment to a scaffolding by workers at a lower level so that a portion of the support post extends above the scaffolding's top level work surface.  Apparatus installation entails pivotably attaching rails to a first support post, which is raised to the edge of the scaffolding and attached. A second support post is then pivotably attached to the free ends of the rails and similarly raised and attached to form a barrier along one edge of the scaffolding. Auxiliary rails may be pivotably attached to an installed support post from the lower level, and the free ends of these auxiliary rails may be pivotably attached to a third support post, which may then be raised and attached to form an adjacent safety barrier. A final barrier may be erected by way of a finishing post, which may be used to attach auxiliary rails to a previously installed support post. An advantage of the apparatus is that no workers are required to be present atop an unsafe top level of a scaffolding while safety barriers are being installed.

Abstract: A process of making molds and inserts where each mold or insert consists of superimposed plates, tightly secured together, having the hollow form(s) or pattern(s) been cut in place. The hollow form(s) or pattern(s) were cut by means of laser or similar cutting machine, which is not possible to do in the blanks or solid pieces that are used to make most molds or inserts because the material to be cut is too thick. The preferred height of the mold or insert was reached by using the proper amount of plates. Superimposed plates with pre-cut pattern(s) can easily be used to make any mold or insert despite its thickness or the intricacies of the pattern(s).
