Title: Grill
IPC: A47J37/06
Filed: 1995-07-07
Abstract: Grill which makes it possible to solve the problem of fumes and gases released in traditional grills without introducing the difficulties inherent in the lack of uniformity of the heat distribution in the plane of the grill, given that the heat sources 2 which are under the area of the foods, i.e. under the grill 1, are protected by deflectors 3 which prevent the fat which may fall from the foods placed on the said grill coming into contact with the said heat sources. The figure shows the grill in an overall view, in perspective, where, for clarity of the view, one of the side panels has been partially cut away, making it possible to see the grill 1; the heat sources 2, the deflectors 3, the geometry of which comprises, in the example shown, the two ramps 31 and 32; the removable tray 4, the handle 5 for controlling the gas-flow- regulator valve, the lighter 6, the ventilation holes 7 for cooling the front panel and the double insulation walls 8. <IMAGE>
Patent PT-102135-A (PT)
Title: Tank for transporting and unloading pulverulent products
Inventor: COUTINHO VALDEMAR DA SILVA
IPC: B60P3/00
Filed: 1998-03-18
Abstract: The invention relates to a metallic reservoir of cylindrical shape that, having special forms of construction, individual devices and other equipment, allows the transportation of pulverulent products more securely than is usual, on account of its low centre of gravity. This reservoir (tank) may be mounted directly on the chassis of a lorry or semi-trailer, for transportation. The inner base of the tank is constructed with metallic ramps sloping at 4 degrees that flow at least to two lower orifices to which the piping system that will convey the product to the outlet hole is connected. This base is totally covered by fine fluidifying fabrics, the aim of which is to generate a constant vibration by means of the passage of pressurized air (between 0.6 kg/cm2 and 1.8 kg/cm2, depending on the product contained), which will move the product towards the outlet orifices with a view to its being unloaded. The external shape of the reservoir - which is totally cylindrical - thus allows it to be mounted lower than equivalent tanks, the latter having lower tapering cones for unloading, and therefore requiring their centre of gravity to be higher relative to the ground, making balancing of the reservoir more difficult. Its totally cylindrical shape, in addition to facilitating construction, results in a lower final weight for the entire assembly, which in turn results in an increase in the available transportable load. <IMAGE>
