Patent CA-2033063-A1 (CA)
Title: Methacoal integrated combined cycle power plants
Inventor: KELLER LEONARD J
IPC: F23J15/00
Filed: 1990-07-02
Abstract: ABSTRACT      Methacoal Integrated Combined Cycle Power Plants comprise a thermal separation plant for producing condensate liquid fuel and particulate carbonaceous fuel from Methacoal fuels, gas turbine plants for burning the liquid fuel to produce electric power; steam turbine generator plants for producing electric power; a boiler plant for producing steam for steam turbines; a small firebox for burning reactive particulate carbonaceous fuel, with minimum retention time for high temperature combustion gases and minimum oxygen required for combustion, thus minimizing emissions of nitrogen oxides and hazardous ultra-fine particulates; and means for controlling ash fusion and slagging problems.     The two generating plants are respectively sized to provide the capacity required, and to consume the two fuels in the proportions produced from the Methacoal fuels, during normal operations, allowing fuel inventory control.  Gas turbine exhaust gases provide most combustion air for burning particulate fuel.  Other uses of gas turbine exhaust heat facilitate control and achieving the high overall efficiencies.  capacity is about one-fourth gas turbine generated power to three-fourths steam turbine generated power for these new plants.  Conventional combined cycle power plants have about two-thirds gas turbine generated power and only one-third steam turbine generated power.  The invention facilitates low-cost retrofitting of steam power plants. New power plants will be much less costly that other coal or lignite power plants available, including fluid bed combustion plants and integrated gasification combined cycle plants.

Abstract: - i -Parking hand brake for a motor vehicle and manufacturing process of its brake lever.                       ABSTRACT.         Brake designed to be connected to a brake cable (15),  comprising a ratchet plate (1, 2)  fixed to the floor of  the vehicle,  a pawl  (4)  designed so as  to interact with the ratchet plate (2), and a handgrip lever (6) equipped with a push-button (18) associated with the pawl;  it comprises a cassette casing (5) mechanically integral with the lever, containing the ratchet plate (1, 2) and the pawl (4), articulated on the ratchet plate and on the end of the brake cable (15). The cassette (5) is formed  from  two  end  plates  (5a)  between  which  are arranged the ratchet plate (1) and the pawl (4),  and which are fixed to the lever (6). Because the lever is split into a grip lever (6) and a cassette casing (5), it is possible to make only the latter from sheet metal so as to enable it to withstand forces, whilst the lever (6) can be made from plastic moulded into various shapes depending upon the desired aesthetics. This arrangement reduces the weight and the cost price of the brake, and permits automatic assembly of its constituent parts, with the exception of the plastic lever (6).
