Title: Reaction vessel having a charge of spherical elements
IPC: G21C5/00
Filed: 1972-07-21
Abstract: 1355599 Reactors HOCHTEMPERATURKERNKRAFTWERK GmbH (HKG) 21 July 1972 [21 July 1971] 34315/72 Heading G6C A nuclear reactor comprises a reaction vessel having a charge of spherical fuel elements which are circulated during operation, there being at least two groups of spherical fuel elements with the elements in each group being of the same diameter but the groups of elements being of different diameters from each other. The fuel elements are uniformly mixed together with the different diameters selected such that the circulation of the elements does not cause substantial segregation of the groups. Where the charge comprises two groups, these may for example comprise elements having respective diameters of 58 and 61 mm. The provision of such groups prevents the fuel elements from adopting an arrangement corresponding to the densest possible packing, in which each element is in contact with twelve neighbouring elements, so that when the control rods are advanced into the charge the stresses applied to the elements and to the tips of the rods are considerably reduced. Fracturing of the fuel elements, particularly at the greater depths of penetration of the control rods, is thereby prevented.

Title: Improvements in or relating to visual signalling systems
IPC: G09F9/307
Filed: 1928-11-22
Abstract: 317,271. Shipton, E. Nov. 22, 1928. Monogrammic signals.-Relates to an electric signalling system for displaying a selected number or sign simultaneously in a number of different places, for example in hotels or auction rooms, and for giving an audible signal to call attention to the number. The apparatus, which embodies a series of monogrammic signs, may be used in conjunction with existing telephone systems. Fig. 6 shows a field of lamps 1 - - 8 arranged for displaying different numerals by selective illumination, the lamps being of the well-known type 23, Fig. 4, used in telephone systems. Fig. 1 shows an alternative arrangement of lamps 1 - - 20 for the same purpose, three adjacent fields being provided so that three-figure numbers may be signalled by means of sets of keys 33, 34, 35 for the hundreds, tens and units digits respectively. After depressing the selected keys to signal the required number in different parts of the building by means of multiple connections, the operator presses a button 36 to ring bells 37 to call'attention to each visible signal. By pressing a button 38 locking-plates are operated to restore the keys to normal. For the lamp connections, the wires multipled to each telephone in intercommunicating systems may be used in such a way as to avoid interference with telephone speech, for example by employing direct current and connecting the lamps up through sufficiently high impedance. In an intercommunication or automatic telephone system a special common line independent of the telephone system proper may be provided, access to which is available both to the party called on the visual signalling system and the party calling. Fig. 8 shows the invention applied to an automatic telephone system. For ordinary calls relays P, PV are connected to the test wiper 51, and the relay PV does not energize. When the special number for this service is dialled, the relays P, PV operate in series with a relay C and extend the loop to a relay A1. The calling party next dials a number, say the digit 7, allocated to the called party. The digit 7 is repeated by the, relay A1 to a magnet W which sets a stepping switch SS to select the appropriate signal lamps, and at the end of the digit the relapse of a relay VB completes the circuit of the clamps and of the associated bells 85, 86. The called party may connect himself at the nearest telephone instrument over a final selector FS1 to the calling party over the special circuit. For signalling at distant stations the digit may be repeated over a lead 87 to a stepby-step switch SS1 similar to SS.

Abstract: 154,936. Oesterreichische Siemens- Schuckertwerke. Jan. 29, 1916, [Convention date]. Addition to 145,589. Drawings to Specification.. Systems for continuous-current motors only.- Direct current motors employed in connexion with batteries or other generators for ship propulsion, and started according to the method described in the parent Specification, are controlled in accordance with the following sequence of changes, beginning with the lowest speed and proceeding to the highest. (1) The motor armature is connected to one-half of the battery, the field being fully excited. (2) The field is reduced to one-half strength by means of a regulator. (3) The armature is connected to the entire battery and the field restored to full strength. (4) The field is again reduced to one-half strength. In the case of two motors, they may be changed from series to parallel instead of using a divided battery. For reversing, especially where it is required to change quickly from the highest forward to the highest reverse speed, a resistance is switched into the armature circuit, and then without disconnecting this from the main, the field is changed from positive to full negative value, thus braking the motor regeneratively and restarting it in the opposite sense.

Title: Method of Making Flocked Sheet Material
Inventor: HOLROYD ERIC
IPC: B32B5/16
Filed: 1966-08-06
Abstract: 1,180,219. Flocked sheet material. DUNLOP CO. Ltd. 4 Aug., 1967 [6 Aug., 1966], No. 35296/66. Heading B2E. [Also in Division D1] Flocked sheet material is produced by coating a base sheet with an adhesive in a pattern by bringing the sheet while it is supported by an embossing roller having an embossed pattern into contact with a coating roller coated with the adhesive applying flock fibres to the adhesive and drying the adhesive. The embossing surface may be provided by means of a closely-fitting matrix having the desired pattern which can be preformed and then secured to the circumference of the roller by means of adhesive. The desired pattern in the matrix can be obtained by cutting the pattern in a blank of suitable material e.g. vulcanised rubber, or by making the pattern of a greater thickness than the remainder of the matrix. The embossing roller can be of inflatable rubber or suitably reinforced rubber e.g. textile or wire reinforced rubber. Provision can be made to apply a vacuum along the edges of the matrix and/or through any "cut-outs" in the matrix. In the example the embossing roll 4 (Fig. 1) comprises a hollow metal cylinder having an endless matrix of vulcanised rubber providing a repeating pattern corresponding to the size and shape of a mat for covering the wheel arch of a motor car. Unvulcanised rubber base sheet is fed into the nip between the right-hand distributor coating roll 3 resting on the licking roll 1 which is partially immersed in a rubber latex adhesive. A bar 6 placed against the distributor roll removes surplus adhesive. The coated sheet is then passed through an electrostatic flocking apparatus where a textile flock is applied, and then passed through a vacuum extraction unit which removes flock from the uncoated portions of the sheet. The flock coated sheet is then dried by passing through a drying tunnel, cut into lengths and vulcanised on heated, vacuum assisted moulds. The matrix can alternatively be in the form of an endless belt (Fig. 3 not shown).

Title: Improvements in processes for producing metal sponge
IPC: C21B13/08
Filed: 1929-11-19
Abstract: 343,954. Metal sponge. GUSTAFSSON, E. G. T., 95, Birger Jarlsgatan, Stockholm. Nov. 19, 1929, No. 35366. Convention date, Nov. 28, 1928. [Classes 72 and 82 (i).] In a process for producing metal sponge, e.g. iron, cobalt, chromium nickel or chrome iron sponge without fusing the ore or metal, finely divided ore and carbonaceous reducing agent and/or thermic reducing agent in excess of the amount required for the complete reduction of the ore are intimately mixed and transformed into briquettes or other form of pieces, and the briquettes &c. are reduced in a shaft or rotary furnace by heat given off by combustion gases of such a character that they burn at least part of the excess of reducing agent in the briquettes. The excess of the reducing agent is applied to the surfaces of the briquettes by powdering or blowing the briquettes with powdered coal or rolling them in the coals before the briquettes are dried. The shaft furnace 12, Fig. 1, is provided with an annular combustion chamber 16 for the fuel burnt in burners 17, Fig. 2, and the gases produced pass through openings 18 into the reducing part 12b of the furnace. The gases produced pass upward through the furnace charge and with the addition of air supplied through the openings 19, 20 from pipes 21, 22 are converted into oxidizing gases which preheat the charge in the part 12a of the furnace. The sponge passes into the cooling zone 12c, the cooling being effected by a double.walled hopper 30 in the interspaces of which air or water is circulated. The cooled sponge is discharged by screws 32, 33. In the rotary furnace, Fig. 3, the briquettes are fed into the preheating part 12a where the combustion gases are burnt with air from the ports 19, 20 and pass into the reduction part 12b where they are acted upon by gases produced by the combustion of gases from an electric furnace 53 in a burner 17 with air supplied by a pipe 58. The partly-reduced charge passes by an opening 51 into a shaft 52 and thence into the furnace 53 where the reduction is completed, an ore carbon charge being introduced through the hopper 14a to increase the production of reducing gases. Thermic reducing agents such as ferro-silicon, ferro-aluminium, .ferro-aluminiumsilicon or aluminium may replace, wholly or partly, the carbonaceous material.
