Patent NL-9400648-A (NL)
IPC: B29C45/02
Filed: 1994-04-22
Abstract: In a method of molding resin to seal electronic parts, an internal die space defined at least by pots, cull portions, resin passages and cavities when an upper mold section and a lower mold section are closed, is cut off or sealed from the exterior atmosphere. Thereupon the die space is evacuated using a first evacuation by a vacuum source and a second or instantaneous evacuation by an instantaneous evacuation mechanism. The vacuum source for the first evacuation may be an active vacuum pump, while the instantaneous evacuation mechanism may be a vacuum tank that has been previously pumped down, for example. According to this method, it is possible to quickly improve the degree of vacuum in the internal die space by efficiently and reliably discharging air, moisture and gas from the internal die space to the exterior due to a synergistic action of the evacuation and the instantaneous evacuation. Consequently, the formation of voids in resin molded members is prevented.

Title: Multiple mould assembly and process for manufacturing construction elements in concrete and other similar materials
Inventor: SANTOS JOSE CARLOS VIEIRA DOS
IPC: B28B7/00
Filed: 1991-07-31
Abstract: The invention relates to a process for manufacturing construction elements in a completely automatic manner, using a moulding system applied to a moulding machine of essentially conventional type. The process is characterized in that it allows the mass-manufacture of moulded components, economically and rapidly, providing a high-quality product. The device used in the process according to the invention is provided with a vessel for the raw material, a store for pallets and a transportation system which takes successive pallets to a moulding station from where each pallet emerges with the moulded components. A control device - for example with a suitably programmed microprocessor - automatically controls all the operations. The objectives of the invention are achieved essentially by the addition, to the basic moulding elements - a mould and a countermould - of the third element: a set of spikes which acts as removable base of the moulding system.

Title: Free-standing sliding gate
Inventor: ERDETSCHNIG ALFRED
IPC: E05D15/06
Filed: 1995-01-17
Abstract: A sliding gate that runs on rollers (7, 8) mounted on two roller blocks anchored in the ground, comprises a box section (1) that has on its lower wall a longitudinal aperture (5) through which the roller blocks (3) project into the interior of the box section (1). The rollers (8) that run on the flat inside upper wall (10) of the box section (1) are cylindrical rollers. The rollers (7) that run on the inside of the lower wall of the box section (1) are groove rollers which engage with ribs of diametrically opposite contour, running in the longitudinal direction of the box section (1) immediately alongside the longitudinal aperture. Without using lateral guide rollers, this design provides precision guidance of the sliding gate when the latter is opened and closed.
