A method for treating ash produced by a waste coal fluidized bed reactor or boiler 10 in which hot ash fines and heated secondary air are introduced into the reactor or boiler as the coarse ash is cooled. An ash treatment system 20 for cooperation with a fluidized bed reactor or boiler 10 operating on waste fuel having a high ash content receives and classifies (C1) hot ash from the reactor or boiler, returns ash fines (48) to the reactor or boiler, cools (35) coarse ash fines (C3) for disposal and burns (C2) carbon associated with the ash received from the reactor or boiler.

A gas insulated switch device has at least two hollow cylindrical containers 50, 51 each accomodating top end portions of a system of line cables 11A, B, 12A, B, and a disconnector having contacts 30A, B, 31A, B coupled to the line cables via detachable conductors 27A, B, wherein electrical tests on the cables, etc. in the first container can be conducted from a test window 43 formed in a side wall of the adjacent second container, by means of a test tank 19 attached thereto. The side walls of the first and second containers comprise a pair of opposing windows 44, 45 that are coupled to each other, via an electricallv insulating spacer 24; branch conductors 26 within the first conialner have inner end portions that can be selectively coupled to the line cables or the contacts of the disconnector within the first container, and have outer end portions 25 projecting into the second container through the electrically insulating spacer. The test tank comprises test conductors 17 which can be selectively coupled to: (1) the end portions 25 of the branch conductors projecting into the second container, (2) the end portions of the branch conductors and the ends of the line cables within the second container, and (3) the contacts of the disconnector within the second container.

A motor-driven power steering system for a vehicle is disclosed which comprises a motor (13) operatively connected with the steerable road wheels and adapted to be energized by a power source (11) for power assisting the steering motion caused by the operator through a steering wheel (1). An electromagnetic hysteresis clutch (14) is interposed between the motor (13) and the steerable road wheels for electromagnetically connecting the motor (13) with the steerable road wheels in a manner such that the assisting torque transmitted from the motor (13) to the steerable road wheels is continuously changed in accordance with the exciting current supplied to the clutch (14). A control unit (9) is provided which is adapted to receive the output signals from a torque sensor (3) and a vehicle speed sensor (10) for controlling the operations of the motor (13) and the electromagnetic hysteresis clutch (14) in a manner such that the current supplied to the motor and the current supplied to the clutch are respectively controlled in an appropriate manner in accordance with the detected steering torque and the detected vehicle speed.

A display device for a torch l3 with an enlarged head comprises a display panel l which can be suspended by means of a slot 3, a hinged loop 6 at the lower edge of the panel, which in use extends obliquely and fits round the underside of the torch head, on a hinged tab 8 on the lower edge of the panel inside the loop, which is pivoted forwards so as to seat on the torch lens 33 and against the inside of the lens rim l6. By these means the torch is reliably held suspended, but can be handled by a prospective purchaser and can be easily removed from the device and replaced in it.

A phase shifter according to this invention comprises circuit groups on a phase advance side (A) and on a phase retardation side (B) in each of which N phase shifting circuits (A 1 to An, B 1 to B n ) of constant amplitude are connected in cascade, and in which the time constants of the successive phase shifting circuits are set at a geometrical progression of a fixed ratio α, while the time constants of the phase shifting circuits on the phase retardation side (B) are made times greater than those of the corresponding phase shifting circuits on the phase advance side (A). Thus, any desired difference can be attained according to the value a, while a desired phase difference can be attained according to the value (3, and the limits of a frequency band width are eliminated by increasing the number of stages N of the cascade connection of the circuit group.
摘要:
The storage medium 30 for an optical data storage system is a contiguous laminate formed by a plurality of layers 18, 19, 20 of photochemical hole burning material, such layers individually exhibiting inhomogenous absorption spectrum characteristics spanning different, successive wavelength ranges. This arrangement greatly expands the cumulative or overall absorption band of the storage medium available for laser hole burning to implement data bit writing, and thus increases the storage density at each memory site. The absorption spectrum characteristics of the layers can be varied by including coloring dyes in the layers.
摘要:
Method and apparatus for manufacturing a sheet-prepreg reinforced with fibers wherein a sheet of fibers such as warp or woven fibers such as fabrics is conveyed between a pair of band belts one of which is coated with a film of thermoplastic resin which has been heated higher than its softening point to enhance resin-impregnating efficiency and prevent the impregnated resin from contacting air. Further, when the sheet of fibers or woven fibers is conveyed in this manner, the molten resin is not maintained on the manufacturing line, thereby preventing it from being deteriorated by heat. The apparatus can be thus kept under operation for a long time and the sheet-prepreg reinforced with the fibers can be made much higher in quality and the deterioration of the impregnated resin can be further delayed.
摘要:
A flotation cell for recovery of minerals from ore using a three phase system flotation process provides improved metallurgical recovery through improved pump rotor/stator 24, 26 and cell design by establishing good zonal separation within the cell and minimizing froth turbulence, providing uniform aeration in the cell, and accommodating higher aeration volumes before encountering turbulence. Parameters for the rotor/stator pump assembly 22, a deflector vane 36 forming part of the stator, and for the pump assembly/cell configuration are disclosed.
