Abstract: A perforated steam plate mainly consists of a retaining plate and an upright tube vertically connected to the retaining plate via a central hole thereof. The retaining plate is a convex plate and therefore allows an adequate space between the retaining plate and the surface on which the retaining plate is positioned. Both the retaining plate and the upright tube have a plurality of perforations evenly formed on their entire surface. When the perforated steam plate is put into a common boiler or a cooker, raw rice to be boiled may be adequately separated from the bottom surface of the boiler or the cooker by the steam plate. In the course of steaming, steam formed by heated water inside the boiler or the cooker permeates from the perforations on the retaining plate and the upright tube to every corners of the boiler or the cooker, making the boiled rice more delicious.

Abstract: Machine for extracting juice from citrus fruit in which the fruit are squeezed between a fixed plate (41) and a movable plate (42) mutually convergent at their lower part. At the beginning of every operative cycle, the fruit (6) is introduced between the plates from their upper part. During the first half of the operating cycle, the movable plate (42) approaches the fixed plate (41) by the action of a crank (31-32-34) - connecting rod (35) unit controlled by a motor reducer (30). The approaching movement of the movable plate (42) causes the squeezing of the fruit (6). The squeezed juice falls into the hopper (22) and, then, into the container (8). Afterwards, the movable plate (42) goes away from the fixed plate (41) and the squeezing residual product (6A) comes off said plates (41,42), it falls on the inclined grill (23) and it slides from the grill into the drawer (26).

Abstract: A burner for the combustion of a fuel plus air mixture comprises a central nozzle pipe having an inner surface with a portion which diverges outwardly. An axially moveable plug is positioned within the nozzle pipe and includes an outer wall with a diverging section extending within the diverging section of the nozzle pipe.

Abstract: A pressurized incineration method for pressurized incineration of a solid waste material to produce electrical and thermal energy is disclosed. A combustion chamber is fueled by a solid waste fuel. The chamber is pressurized by an air compressor and the fuel is combusted. The hot compressed gases created by combustion pass out of the combustion chamber into an exhaust line that splits so as to provide hot gases to a turbocharger and a separate power recovery turbine. The turbocharger and the power recovery turbine have a rugged design so as to handle compressed gases containing corrosive effluents and particulate matter. If necessary, gas cleaning equipment may also be used to reduce corrosive effluents and particulate matter to an acceptable level in the inlet gas stream to both the turbocharger and the power recovery turbine. Expansion of a portion of the hot compressed gas through the turbine section of the turbocharger provides energy to drive the turbocharger's air compressor.

Abstract: The invention is a novel transit system in which vehicles are piggybacked onto electrically operated upper sled modules for longer distances or between critical high volume areas such as city centers and airports. The front wheels of the Electric vehicles (EVs) in this system are carried on an upper sled module which is connected by a strut or fin to a lower airfoil wing travelling in a generally below grade duct or conduit. The EV uses its own power to move the articulated unit from co-axial AC and DC motors supplemented by a parallel power supply and signals system. Vehicles mounted on the sled units are automatically spaced in response to central computerized timing and speed controls so as to ensure proper separation of vehicles using the guideway. Piggy backed vehicles can quit the guideway at predetermined nodal points to revert to conventional vehicular travel on the public highway system.

Abstract: A twin-axle rail-bogie which incorporates a steering mechanism for positively steering one or both of the axles of the rail-bogie in proportion to the rotation of the frame of a structure supported by this rail-bogie. Steering is achieved by slidably mounting one of the axle end supporting assemblies onto the chassis of the bogie so that this assembly is longitudinally slidable and thus causes the one axle having one of its ends connected thereto to pivot forwards or rearwards out of its normal transverse position relative to the transversally opposite supporting assembly which holds the other end of the one axle and then acts as a pivot. An operating arm attached to the frame near the one supporting assembly is used for moving via a linking mechanism the one supporting assembly in such a direction as to cause the one axle held by this supporting assembly to pivot in the same direction but at an angle smaller than and proportional to the frame with respect to the chassis of the bogie.

Abstract: A pollution control system for removing harmful elements from industrial smoke streams comprises a reciprocating pump assembly that draws smoke from a furnace or the like and delivers it through a passageway where the smoke is treated sequentially to remove harmful elements therefrom. Disposed along the passageway is an atomizer station, a first fibrous filter, an ignition chamber, and a second fibrous filter. Having traversed the passageway, the smoke is ejected into a large tank of water and bubbles to the surface thereof, thus being further cleansed. From the water tank, the cleansed smoke stream moves up a stack, through a final fibrous filter, and into the atmosphere where it poses a substantially reduced environmental hazard.

Abstract: Harmful constituents are removed from non-combustible solid waste, such as incinerator ash, by continuously feeding a mixture of the solid waste and a combustible excitation material into a reaction chamber, igniting the mix in said chamber and causing it to react in the presence of oxygen until the heat of the reaction causes the solid waste material to become a molten slag and the temperature within the chamber above the molten slag is high enough to destroy substantially all of the harmful constituents in the gaseous effluent released by the formation of the molten slag. The excess molten slag is conducted from the reaction chamber. The effluent is conducted from the reaction chamber into a second chamber where it is rapidly cooled to cause particulate material to precipitate out of the effluent. The effluent is thereafter treated to remove substantially all of the remaining particulate and harmful gases to achieve acceptable environmental quality. The thus treated effluent is released into the atmosphere.
