Filed: 1955-09-09
Abstract: 783,225. Welding by pressure; rolling. LICENTIA PATENT-VERWALTUNGS GES. Sept. 9, 1955 [Sept. 9, 1954], No. 25877/55. Class 83 (4). A welding installation for welding hot billets supplied from a reheating furnace to form a continuous bar for a continuous feed to the rolls of a roller mill, comprises at least two movable buttwelding machines, a feeding track along a line from the furnace towards the roller mill, a return track and a control arrangement for the machines such that one machine is stepped at the discharge point of the furnace to grip the trailing end of the preceding billet and the leading end of the following billet and is then caused to move towards the roller mill at a speed greater than the feeding speed to form a loop in the welded bar whilst the second or last machine is caused to return to the furnace. Three flash butt-welding machines 4, 5, 6 are mounted on wheeled carriages on an endless oval track 14 located between the reheating furnace 1 and feed devices 8, 9, a deburring device 10 with feeler rollers 13 being arranged between the feed means 8, 9. Feeler rollers 11, 12 in contact with a billet produce impulses to control the advance of the machines. Each machine comprises clamping-jaws 3, 15 and a pair of aligning jaws 18 adjacent each pair of clamping jaws, the clamping jaws operating after the aligning jaws. With the machines in the positions shown in Figs. 1 and 2 the machines 4, 5 are stationary, the machine 4 clamps the end of the welded bar 7 in its jaws 15 and the machine 6 releases the bar and travels along the track towards the furnace. While the machine 6 is moving, a billet is ejected from the furnace 1 until it contacts the end of the bar 7. The left-hand jaws 3 of the machine 4 clamp the billet and welding current is switched on. When a loop formed beyond the machine 5 in the previous operation has been straightened the machines 4, 5 are set in motion, the machine 5 at feeding speed and the machine 4 at twice this speed, thus forming a loop between the machines. When the billet end from the furnace passes the feeler 11 the speed of the machines 4, 5 is reduced and when it passes the feeler 12 the machines are stopped. The machine 6 has meanwhile reached the original position of machine 4 and grips the end of the bar 7 and the process is repeated. The track may be circular, rectangular or in two parallel tracks with automatic points at the ends.

Title: Improvements in or relating to apparatus for measuring and/or controlling the ratio between two quantities
IPC: G05D11/13
Filed: 1938-09-12
Abstract: 520,330. Indicating and recording apparatus. BAILEY METERS & CONTROLS, Ltd. Sept. 12, 1938, No. 26601. Convention date, Sept. 11, 1937. [Class 106 (iv)] [Also in Groups XXXV and XXXVIII] Apparatus for determining and/or controlling the ratio between two quantities comprises means for periodically establishing two electric impulses which are normally of equal duration, means controlled in dependence on the values of the quantities and adapted to disturb the equality of the impulses upon variation of the ratio and means adapted under the influence of such disturbance by varying the relative degrees of control exerted by the two quantities to reestablish equality of the impulses and thereby to effect an indication and/or control of the ratio. In the apparatus shown in Fig. 1, two known flow meters 7 measure the flow of fluids in conduits 1 and 2 and operate levers 12 and 15. Contacts 24 and 28 are moved by these levers and co-operate with contacts 21 and 27, the latter being reciprocated at the same rate by synchronous motors 17 and 25 acting through cams 19 and 26. Contacts 21 and 24 are situated in the circuit of a coil 33 of a motor 34 and contacts 28 and 27 in that of a coil 35 producng a magnetic field opposed to coil 33. When the ratio of the flows in conduits 1 and 2 changes the current impulses through coils 33 and 35 become unbalanced and an armature 36 is rotated. This adjusts a link 32 in the operating mechanism of contact 28 until equality of impulse is again produced. The change in position of the link to produce this effect is a function of the flow ratio and thus a suitably shaped cam'connected to the armature may operate an arm 3 to indicate the ratio on a scale 5 and record it on a chart 4. The flow in conduit 1 may be controlled by a valve 6 controlled by a motor 40 similar to motor 34 and connected to the various terminals in parallel therewith. In an alternative construction for a compact apparatus the contacts 21 and 27 are arranged on one arm actuate by a single cam. In another arrangement the meters 7 and 13 operate a differential beam 72 to the centre of which is attached a link 75 operating a contact 78 co-operating with a contact 81. The pair of comparison contacts 82 and 83 are in this case driven with constant motion as the movements of contacts 78 and 81 in this construction vary if any difference arises in the ratio of flows. The apparatus operated by these two pairs of contacts operates in the same manner as the corresponding parts in 'the first construction.

Title: Improvements in or relating to processes for carrying out exothermic chemical reactions under pressure and at a high temperature
IPC: C01C1/04
Filed: 1926-10-25
Abstract: 268,721. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude, (Assignees of Soc. Chimique de la Grande Parcisse Azote et Produits Chimiques). March 31, 1926, [Convention date]. Catalytic processes and apparatus. - In the synthesis of ammonia and other catalytic processes carried out at high pressures and temperatures and with absorption of a part or nearly the whole of the heat of reaction bv the fresh reaction gases, there is circulated between the container for the catalyst and the outer pressure resisting wall a gas which maintains the temperature of the wall within safe limits and is discharged to the outside of the pressure tube. After cooling, if necessary, the gas may be used again for the same purpose, or may form the reaction mixture in the same or another catalyzing vessel. Or it may consist of gas which has already been treated. Fig. 1 shows the catalyst enclosed in a vessel B coated with heat-insulating material, which may be thicker near the lower end. Gas passes through the space between the vessel B and the pressure tube C from a pipe D to a pipe E; it then traverses a cooling coil F, a pipe G, and tubes H embedded in the catalyst, being further heated, if necessary, by an electric resistance I before passing downwards in direct contact with the catalyst. The inner tubes H may be of variable heat conductivity, ur may have a larger surface in the hottest zone. The direction of the gas in the space between the vessel B and tube C may be reversed. Further heat may be imparted to the fresh gas by the reaction products, in a heat exchanger within the pressure tube. In another arrangement, the fresh gas is divided inside or outside the pressure vessel into two portions, which pass respectively inside and outside a heatinsulating tube situated midway between the catalyst container and the pressure vessel. The inner gas current then flows down through the catalyst, and after cooling and separation of the reaction product it may rejoin the other fraction and the mixture may be sent to the next catalyzing vessel or returned by a compressor to the same vessel. A third arrangement employs a catalyzing chamber similar to that shown in Fig. 1, but the annular space between the catalyst container and the pressure tube is supplied with gas which has been employed for the reaction, cooled, and separated from the product: after cooling again, the gas from the annular space passes on to the next catalyzing chamber. Specifications 150,744 and 171,970 are referred to.
