IPC: F23G5/22
Filed: 1972-01-12
Abstract: 1326872 Incinerators CIGECO COMPAGNIE DES CONVOYETJRS SA 12 Jan 1972 [18 Jan 1971] 1483/72 Heading F4B An incinerator comprises an elongated truncated conical rotary drum 1 mounted on a motor vehicle with its axis inclining downwardly from an inlet end opening 33 to the ash removal end 34, burner means 56 in the drum, means for cooling and purifying the combustion gases, and means for supplying combustion air to the drum and the burner. The drum has an outer wall 39 and an inner wall 36 of thin sheet metal panels removably attached to a framework, and the air supply to the drum passes through the hollow wall to exit from apertures 37 formed in the inner wall. Lifters 38, Fig. 7, arranged in front of the air openings 37 which are directed towards the narrow end of the drum serve as air deflectors. The combustion gases pass through a tortuous passage formed by baffles 12, 14, 15, Fig. 2, are washed by a water spray and are evacuated through a stack 28 by a fan 27. The burner 56 is fed with gas from a tank of liquefied gas, the pressure of gas fed to the burner being controlled by passing air heated in an exchanger 58, Fig. 3, in the combustion gas path, or ambient air through evaporator tubes in the fuel tank under the control of a pressure sensor. The gas pressure at the burner is controlled in accordance with the temperature in the furnace by opening or closing a valve in a high pressure gas feed line, which is by-passed by a low pressure feed line. A burner located in the waste gas path may be controlled in accordance with the composition of the exhaust gases. The burner in the drum 1 has two heads, 53, 54 located at the middle and near the ash exit end of the drum respectively, Fig. 3. Refuse fed into the furnace is deposited on the vanes 61 of a paddle wheel mounted at the rear of the vehicle, Fig. 9. A shoot 63 receives refuse from the vanes at the top of their travel, and a piston 67 with a shutter 68, which closes the shoot 63 at the forward end of the piston stroke, feeds the refuse into the furnace. The paddle wheel 7 is moved step by step as the piston 67 is reciprocated. The vehicle, Fig. 1, carries an ash receptacle 5, water tank 11, fuel tank 10 and auxiliary devices 9 such as air supply and induced draught fans and a drive for the drum. The replaceable sheets 42 forming the lining of the drum are held between L-shaped members 43, 44 pivoted on a pin 45 passing through a rib of the drum frame. The sheets 42 are readily removed by extracting cotters 46 to release the members 43, 44, Fig. 5.

Abstract: An aqueous paper pulp comprises cellulose fibre, a polyamide-epichlorohydrin resin and a dialdehyde-carbohydrate. The polyamide-epichlorohydrin resin is of the kind obtained by reacting a polyalkylenepolyamine with a saturated aliphatic dibasic carboxylic acid to produce a water-soluble polyamide containing recurring groups of the formula:  -NH(CnH2nNH)x-CORCO-, and then reacting this polyamide with epichlorohydrin.  The polyamine used may be a mixture or a crude material containing the polyamine.  The dialdehyde-carbohydrate is obtained by oxidizing starch, vegetable gums or alginic acid with periodic acid.  The resin is preferably added to the pulp before the dialdehyde-carbohydrate.  The pulp may also contain carboxymethylcellulose, cationic starch, dye, gelatin and sodium stearate.  Its pH may be adjusted with aluminium chloride or sulphate or with ammonia, The pulp may be made into paper, e.g. on a Fourdrinier machine, and may then be tub-sized with gelatin and calendered.  The paper can be used as a photographic base (see Division G2), or for towelling, bags, tissue or maps.ALSO:Paper made from a pulp comprising cellulose fibre, a polyamide-epichlorohydrin resin and a dialdehyde-carbohydrate is coated with a baryta layer.

Title: Process for the fabrication of fuel elements for nuclear reactors and fuel elements thus obtained
Inventor: BLUM PIERRE
IPC: G21C21/02
Filed: 1966-01-14
Abstract: 1,130,111. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 14 Jan., 1966 [21 Jan., 1965], No. 1934/66. Heading G6C. A spherical fuel element for a pebble-bed reactor is made by moulding a paste comprising a mixture of particles of enriched uranium dioxide and graphite together with a binding agent. The moulding produces a cylindrical fuel kernel which is rendered impermeable by a heating operation in which the kernel is impregnated with gaseous hydrocarbons at 800 to 1000 C. The fuel kernel is next coated with a layer of paste comprising a mixture of graphite and a binding agent and this layer is similarly heat treated with gaseous hydrocarbons at 800 to 1000 C. Finally, the coated fuel kernel is inserted in a recess formed in a ball of graphite and the recess is closed by a plug bonded in position. In a modification, the fuel kernel has a central core of graphite and the fuel mixture forms a layer around the core. In both constructions, since the mechanical strength of the fuel kernel is greater than that of the graphite ball by a ratio of at least 1.5 to 1, the fuel may be readily separated from the ball after irradiation for reprocessing, by merely applying sufficient crushing force to break the ba.1, the kernel remaining intact.

Abstract: 808,379. Severing by tearing. SOC. FOMAC. Jan. 23, 1956 [Jan. 22, 1955], No. 2165/56. Class 31 (1). In apparatus for tearing a strip 1 of paper or cards along longitudinally-spaced transverse preformed lines of perforations of the kind comprising a pair of rollers 3a, 3b which are driven at a greater peripheral speed than a pair of rollers 2a, 2b, the rollers 2a, 2b are driven from an electric motor 4 through a chain 7 which is subjected to the action of a pair of tensioning members 9, 10 pivoted at 11 and acted on by springs 12, 13, the spring 12 being stronger than the spring 13. In operation, when the strip is engaged by both pairs of rollers, it causes the rollers 2a, 2b to rotate at a peripheral speed greater than that derived from their drive, and this causes the tensioning members 9, 10 to swing counterclockwise against the action of the spring 12. When the tensioning member 9 engages an abutment 14, the rollers 2a, 2b are caused to resume their normal speed and the strip is thus subjected to increasing tension to effect tearing of the strip along a preformed line of perforations disposed between the pairs of rollers. Reverse rotation of the rollers 2a, 2b is prevented by means of a pawl 16. The abutment 14 is adjustable according to the spacing between the preformed lines of perforations.

Type-lever machines; keyboard operators.- Relates to machines for punching holes in a sheet or card and simultaneously printing a record on another sheet, of the kind in which the punching-mechanism is connected to the keys of a typewriter, and consists in an arrangement whereby the punching- mechanism is operated only when the papercarriage of the typewriter moves for letterspacing, the arrangement ensuring correspondence of the punched and printed records, since if the keys are not depressed sufficiently to print, the carriage is not released and the punching- mechanism is silenced. The punching-mechanism is preferably of the kind comprising interponents which on depression of the numeral keys 10, Fig. 3, of the typewriter are moved into the path of an actuator operated by an electromagnet 45<a>, Fig. 4, the keys closing contacts 12 in circuit with electromagnets 11 for operating the interponents, and the interponents closing contactc 40 in circuit with the electromagnet 45<a>. There is now provided a pair of contacts 18 controlled by a star-wheel 16 which is geared to the papercarriage 55 of the typewriter, the contacts being in circuit with the electromagnet 45a, the contacts 40, and contacts 68<a> between which is arranged a movable contact 68 operated by 'an electromagnet 72 and spring 76. The key-levers engage a universal bar 14 for closing contacts 13. When any key 10 is depressed, a type-lever 54 is swung upwards, the associated contact 12 and the contact 13 are closed, the contact 40 is closed by an interponent, the contact 68 is moved to the top contact 68<a>, and if printing is effected the paper-carriage moves on release of the key and the contacs 18 are closed by the star-wheel, the circuit of the electromagnet 45a being thereby closed and a punch being operated. If the key is not depressed sufficiently to print, the papercarriage is not released and the contacts 18 remain open, thereby preventing operation of the punch. When the spacing-key or back-spacing key is operated, the contacts 18 are closed, but the electromagnet 45a is not energized. The punching-mechanism can be operated manually and independently of the typewriter, current flowing to the electromagnet 45<a> through the lead 75, lower contact 68<a>, and contacts 40. The contacts 13 may be omitted.
