Patent GB-1468880-A (GB)
IPC: C25C3/12
Filed: 1974-04-29
Abstract: 1468880 Paste for carbon electrode ALCAN RESEARCH & DEVELOPMENT Ltd 29 April 1974 18770/74 Heading C1A A paste for the production of carbon electrodes is made by mixing an aggregate of coke particles with a binder, the aggregate being constituted by a major proportion of fully calcined coke particles and a minor portion of partially calcined coke dust particles recovered from gases discharged from a coke calcining operation, said partially calcined coke particles having been ground before incorporation into the paste. The partially calcined coke dust, before grinding, typically has a bulk density of 0À55 to 0À7 g./cc., 60-80% passing 100-mesh (Tyler), 20-40% passing a 200-mesh and 5- 25% passing a 325-mesh is ground so that suitably at least 40%, preferably 50-80%, pass through a 200-mesh. The partially calcined coke dust particles may be ground in admixture with fully calcined coke particles, which are preferably coarser, in a ratio of between 60 : 40 and 95 : 5. The partially calcined coke dust suitably constitutes 5-10% by weight of the aggregate and the remainder is constituted by fully calcined coke particle larger than 48-mesh and preferably a portion of fully calcined coke fines of smaller than 48-mesh. The aggregate is mixed with a binder, suitably pitch in an amount of 28-35%. A paste for a Soderberg anode comprises an aggregate of 50-60% by weight of coarse fully calcined coke particles, 40-50% by weight calcined coke fines and 5-10% by weight of the partly calcined dust mixed with 28-35% of pitch. A pre-baked carbon electrode may be made by compressing a body of the paste to form a hard mass and then baking.

Abstract: 1,132,739. Storing liquefied gases. PHILLIPS PETROLEUM CO. 29 April, 1966 [30 April, 1965], No. 18879/66. Heading F4P. Prior to re-charging a liquid propane storage container 5, Fig. 1, from a tanker, the filling line 1 is cooled by being charged with a cold liquefied gas and any vapour so formed is removed through a valved branch line 6 connected at a high point 2 of line 1. The cooling liquid is preferably liquid propane withdrawn from the base at container 5 through an open valve 9; a valve 7 at the inlet end 3 of line 1 being closed whilst a valve B in line 6 is open. During re-charging of container 5 valves 7, 9 are open and valve 8 is closed and vapour is withdrawn from container 5 through lines 10, 11, a separating chamber 12 and a compressor 17 which delivers compressed propane through a line 20 and a refrigerant-cooled heat exchanger 21 wherein the propane is re-liquefied and returned through lines 22, 24 to the container 5. The refrigerant, e.g. propane, is .gasified in exchanger 21, reliquefied by compression at 38, cooled at 40 by water, further cooled in an exchanger 50 in heat exchange with liquid propane withdrawn from the base at container 5 by a pump 61 and returned through a line 57 to the exchanger 21. Liquid propane warmed in an exchanger 56 is further warmed in an exchanger 65 and is discharged through a temperature-controlled valve 85 to a receiver; the exchanger 65 being in a closed ethylene glycol circuit.

[Class 64 (iii)] A heat-exchanger comprises flat bands 4 wound spirally and clamped between circular plates 6 by bolts running the length of the apparatus, communicating ports between the channels thus formed being provided in the plates 6. The bands 4 are made of rustless steel. The stand 7 of the apparatus may contain hot water for use in the heat-exchanger. The bands 4 form a pair of channels in heatexchange relation between each pair of plates 6 except for the two spaces on the left hand of the figure in which only single channels are formed. Raw milk enters at inlet 23 and flows through two sets of channels in which it is heated by milk already heated in the apparatus. It then passes through outlet 27 to a centrifugal separator. The milk enters again at port 24 and flows through the left hand side of the apparatus where it is first heated by hot water circulated from the tank 7 and then flows through the single channels where its temperature remains practically constant. The milk then passes through connection 29 to the right hand side of the apparatus and first heats incoming milk and then is cooled by heat exchange with a cooling fluid before leaving the apparatus through aperture 25. The plates 6 are covered on both sides with indiarubber which may be grooved to receive the edges of bands 4.

Filed: 1923-07-30
Abstract: 204,022. Nicolle et Cie, P., and Trepier, P. A. Sept. 13, 1922, [Convention date]. Vibration-dampers. - A friction shock-absorber for motor and other vehicles is arranged so that no braking action occurs for small oscillations but the oscillations of large amplitude are braked, in some arrangements progressively, and comprises a friction washer divided into several segments, each segment being given circumferential play. An arm 1 has secured to it a disc 4 having sockets or recesses. bounded by radial arms 5, each recess containing a segment of friction material, the segment being smaller than the recess circumferentially so that play is permitted between them. The segments 8 bear on plates 6, 7 carried by the arm 2 and the whole device is jointed by a screw and nut 11. For small oscillations no braking action occurs owing to the play of the segments, and as the play may differ for each segment large amplitudes of oscillation bring the friction of the segments into action successively to produce a progressive braking action. A dial may be mounted on the screw and a spring 13 pivoted at 14 may combine the functions of a pointer and friction brake on the dial. The ends of the arms are provided with sleeves and a pivot 19 passing through both sleeves and arms for attachment to the chassis and axle respectively.

Bakers' ovens.-In a " travelling " oven of the kind in which the goods-carrying members are pivoted at one end to the conveyer chains while their other ends are so supported that the members are maintained in an horizontal position when moving from an upper to a lower flight, the driving-chains are located outside the oven. in the construction shown the oven casing comprises upper and lower arches 22, 23, and intermediate side walls 24 all supported by brackets 25, the parts being spaced to provide slots or guideways, in which move blocks 11 carrying the baking-plates 10. The blocks and the faces of the guideways are formed with interfitting projections and grooves for preventing sideways motion. and each block carries a roller 27 at the end remote from that at which the block is connected to its driving-chain 12 by a spindle 13 or 13<1>. The means for maintaining the blocks 11, and the plates 10 carried thereby, in an horizontal position while passing round the rear end sprockets, and for allowing the plates to tilt at the front end of the oven, are similar to those described in Specification 256,750. The clearance spaces, which must be left to allow the movement of the blocks round the rear end sprockets, are substantially closed by plates 32<a>, 32<b>, spaced to form slots 34 for the movement of the spindles 13, 13<1>, and discs 33, which rotate with the sprocket shafts and are notched as at 33<1> to take the spindles. A sliding door 37 is provided above the upper lap of the conveyer, and a hinged door 38 is fitted between the laps. The oven may be arranged for use as a hot-plate by hinging portions 39, Fig. 5, of the side walls of the oven so that they can be opened to the position shown in broken lines. In this construction both the blocks 11 and the chains 12 move in the guideways. In a further modification, in which doors are provided at both ends, the baking-plates move from one lap to the other outside the oven.
