Abstract: PCT No. PCT/FI92/00238 Sec. 371 Date Feb. 24, 1994 Sec. 102(e) Date Feb. 24, 1994 PCT Filed Sep. 9, 1992 PCT Pub. No. WO93/05340 PCT Pub. Date Mar. 18, 1993The invention concerns a method and a device in the cooling of the circulating material in a fluidized-bed boiler. In the method the fuel (A) is introduced into the circulating-powder combustion chamber (10) of the fluidized-bed boiler into the lower part of the circulating-powder combustion chamber (10) and an inert circulating material, which contains a proportion of unburned powdered fuel (A), is circulated from the top part of the circulating-powder combustion chamber (10) to the lower part of the circulating-powder combustion chamber (10). The flue gases are passed in the method from the powder separator (13) along the duct (15) into the exhaust-gas boiler (16), through whose heat exchanger (16a) thermal energy of the flue gases is transferred further to other useful use. In the method, part of the cooled flue gases are recirculated along the duct (20) into the circulating material and, by means of the cooled flue gases, the capacity of cooling of the fluidized-bed furnace is regulated by affecting the temperature of the circulating material.

Title: Improvements in means for transmitting time signals over electric supply circuits
IPC: G04C13/02
Filed: 1921-01-08
Abstract: 157,213. Trichard, P. July 13, 1917, [Convention date]. Electric clocks.-A system of distributing time from a central station over existing conductors already supplying a constant voltage comprises an auxiliary generator which is connected and disconnected in series with the main line under the control of a standard clock to produce abrupt variation of voltage of low frequency, and as receiver an undamped voltmeter which by mechanical resonance acquires a swing to operate the local signaling device. The transmitting appa. ratus is shown in Fig. 2. The auxiliary generator is connected to contacts A, C. and a resistance is connected to a contact B in parallel with the generator, so that as contact P moves over contacts A, B, C the auxiliary generator is alternately in and out of circuit. The contact P is carried on an arm at the other end of which is a core of soft iron N which is moved in one direction or the other by two coils B, B<1>, connected in parallel to a source of current G and alternately placed in circuit by the hand and peripheral contacts of a standard clock H. The hand has a beat of a fraction of a second. The receiving apparatus, Fig. 3, consists of a coil D branched off the main at 1, 2, with a softiron core F connected by a non-magnetic rod with a core F<1> of another coil D', which acts as a damper. When the movements of the core P due to the variation in voltage in the mains reach a certain critical value by resonance a ratchet R is moved one step to register a minute by a lever L attached to the core F at S<2> and pivoted at S. At the same time a contact J is turned by a rod T<1> attached to the lever L to close the circuit of the coil D<1> and as its core F' is oppositely placed in relation to the coil D<1> to that of F in relation to D the whole core device is locked. The circuit of the coil D<1> is opened by a thermal switch U operating on the contact J. Specification 104,077 [Class 40 (i), Electric signalling systems &c.], is referred to.

Abstract: 438,302. Spray-producers; valves. AERASPRAY MANUFACTURING CO., Ltd., and NEWLIN, H. J., 179, Thimble Mill Lane, Birmingham. Jan. 12, 1935, Nos. 1098 and 12112. [Classes 69 (iii) and 135] An air-pressure sprayer for paint, &c., adapted to give at will a round or flat spray is provided with a single trigger to control the air supply both to the atomizing nozzle and to flattening jets, the first movement of the trigger opening a valve to control the spraying nozzle, and a further movement opening a second valve to control the flattening jets. The trigger 4, Fig. 1, pivoted on the frame of the apparatus controls the needle valve 2 and is provided with a link 16 to open the air valves. Below the needle valve the frame is provided with a stepped bore 7 having a valve seat 8 on which a valve 11 engages, controlling admission of air to a chamber 10 communicating by a duct 17 to the atomizing nozzle, and a second seat 21 closed by a valve 20 controlling a duct 19 leading to the flattening jets 43. The valve 11 is mounted on a sleeve 13 to which are threaded nuts 15, 15<a> between which the link 16 engages. The valve 20 is fixed on the end of a stem 22 carrying a collar 23 engaged by the nut 15 after the valve 16 is opened. The volume of air delivered to the flattening jets may be regulated by a screw valve 25. The spray-head comprises a cap 31 having a flange 32 screwing on the body 1 and a second flange 33 abutting against a shoulder 34. A ring 35 forms a division for two air chambers fed by the ducts 17, and 19 respectively. The paint nozzle 36 screws into the cup 32 and an air cap 18 is fixed on the nozzle 36 by a clamping ring 37. The air-cup is formed with ducts 44, leading to a central nozzle and ducts 43 leading to flattening jets. A rubber sealing ring 44 prevents leakage of air between the distributer and the cap 31. Fig. 3 shows a modification in which the valves are placed above the trigger 46 and are situated in an inclined bore into which is screwed a bushing 48 formed with ports 56. In alignment with this bushing is a second bushing 49 having ports 56<a>, a valve seat 50 being formed between them. The valves 51, 58 are mounted on the same stem and acted on by a spring 65. The valve 58 engages a seat in a sleeve 59 sliding in the bush 49. On pulling the trigger the valve 51 admits compressed air to the chamber 62 and thence to the atomizing nozzle. The valve 58 is simultaneously moved but the pressure of air in the chamber 62 causes its seating to slide until it abuts against an adjustable stop 67 when the valve 58 will open and admit air to the flattening jets. The adjustable stop comprises a rotatable pin 66 having a round head 67 one half of which is cut away. In a further modification the second valve is formed as a ball bedding in the slidable seat which engages with an adjustable stop screwed in the frame coaxial with the valve.

Filed: 1941-01-29
Abstract: 544,903. Coating with metals. GENERAL MOTORS CORPORATION. Jan. 29, 1941, No. 1167. Convention date, Feb. 1, 1940. [Class 82 (i)] [Also in Group XXII] Composite metal is formed by sintering a loose layer of metal powder, distributing a uniform layer of soft low-melting point metal powder on the matrix thus produced, compressing to force this powder into the pores of the matrix and then heating to melt the powder but not dissolve or melt the matrix. The soft metal may be applied continuously in the form of powder 28, Fig. 5, to a steel strip 22 having a matrix layer 20 previously fluxed, if desired. The powder 28 is forced into the pores of the matrix by roll 34 which may also compress and upset projections of the matrix. The strip is then heated by electric elements 38 or otherwise in a furnace 36 containing non-ozidizing gas to melt the soft metal and cooled. If desired a second layer of the soft metal powder may be applied at 44, melted at 46, and cooled at 40 and if this is done the furnace 36 may be omitted. Side guides 48, Fig. 7, may be used to retain the molten metal. The cooled strip may be passed finally through another pair of rolls. Instead of applying a second layer of soft metal in powder form this may be molten and applied by known apparatus. Powders for making the matrix preferably have spherical grains, pass a mesh of 150-200 per inch and are free from oxides. They may be made of copper, iron, aluminium, or alloys thereof by electrolysis, reduction, atomizing &c. The soft metal powder may be made of lead, tin, antimony or combinations thereof and preferably passes a mesh of 2,50-300 per inch if the matrix is a 150 mesh powder. Instead of using a continuous process, the separate steps may be performed on separate pieces of porous metal matrix. The compound strip 22, 20 may be made continuously as described in Specification 496,763 which also describes the manufacture of anti-friction material strongly bonded to a backing, by melting low-heating point metal on a strip so made..
