Title: Method of circulating water through a cooling circuit
IPC: F25D9/00
Filed: 1974-12-24
Abstract: 1493955 Blast furnace evaporative cooling NIPPON KOKAN KK 24 Dec 1974 [28 Dec 1973] 55780/74 Headings F4B and F4U The cooling staves 10 of a furnace are supplied with water from a separator 20 through a delivery pipe 18, and a steam/water mixture returns by a pipe 22 to the separator inlet 24. The level of the water 25 in the separator is measured by a meter 40 and is maintained at a level L1 or L2 according to the selection made on an automatic control device 51. The selection made depends on the reading on the meter 54 which registers the steam content of the steam/water mixture in the return pipe 22. Initially on starting up the furnace the L1 level is selected and this is maintained by the device 51 which permits additional water to enter the separator through the valve 26 if the level falls below L1 or shuts off the valve 26 if the level rises above L1 so that the water level is lowered due to the release of steam from the relief valve 34. When the meter 54 indicates a certain steam content has been reached in the return pipe 22, a water level L2 below the inlet 24 is selected and the control device 51 functions as above to maintain this new level.

The porous material is preferably nickel. The electrode elements are sealed by means of annular sealing rings 20 preferably made of neoprene. An uncured rubber adhesive is first applied to the metal surface and is then heated to partially cure the same. A body of uncured neoprene is then moulded against the partially cured adhesive by applying heat and pressure which completely cures the adhesive and neoprene.

Abstract: 1,200,747. Fuel batteries. ALLMANNA SVENSKA ELEKTRISKA A.B. 13 Dec., 1967 [14 Dec., 1966], No. 56569/67. Heading H1B. In a fuel battery having inlet and outlet channels for electrolyte the outlet channel is directed such that when the battery is placed in its working position upon a horizontal plane, the outlet channel is inclined at an angle of at least 10 degrees to the horizontal plane and has its uppermost end connected to means for returning electrolyte to the inlet channel of the battery. Preferably the inlet channel is also inclined to the horizontal and both channels are connected at their lower ends to an inert-gas supply to decrease leakage currents and reduce the explosion risk from reactant gases leaking into the electrolyte. As shown in Fig. 2, N 2  is blown into the outlet channel and, in smaller quantity, into the inlet channel 14 for electrolyte in an inclined fuel battery. Electrolyte and nitrogen with H 2 O vapour and gas (H 2 , O 2 ) are led to a separator 18 for electrolyte and H 2 O. The separator has a scrubber and a recombiner for reacting the gas to form more H 2 O. Separated electrolyte returns to the inlet channel 14 of the battery, via chamber 19, mixed with condensate from cooler 24. Other material from separator 18 is cooled in condenser 20 by fresh N 2 , supplied by fan 23, and led to cooler 24 where H 2 O is separated at 24 and condensate is supplied in metered amounts to chamber 19. After acting as coolant in condenser 20 the N 2  is mixed with fresh N 2  supplied by temperaturecontrolled valve 22 and supplied to the battery. A similar system with four cell stacks in the battery and a source of fresh electrolyte is also described (Fig. 6, not shown). The cells may have free electrolyte between the electrodes or may have free electrolyte flowing in channels 45 cut in the surfaces of porous bodies 42, one porous body being attached to each electrode (Fig. 4).

As shown, the chassis 1 has fixed front and rear undercarriages 3, 2 at the shorter spacing and a further hydraulically-actuated foremost undercarriage 4 at the larger spacing, the latter being vertically displaceable so that it can be lowered on to the track 5 to render the undercarriage 3 inoperative. The undercarriage 4 may also be horizontally displaceable along guide 20. In a modification, Fig. 3 (not shown), the shorter-spaced undercarriage (3) is vertically displaceable, whilst the foremost undercarriage (4) is carried by a horizontal beam telescopically protruding from the front of the chassis 1. The tamping tools 7 are height-adjustable and may as shown straddle a single sleeper or, Fig. 3 (not shown), a pair of sleepers. The rail-gripping rollers 8 are shifted by hydraulic cylinders 9, 10 to effect vertical and lateral alignment. Monitoring systems.-In Figs. 1 and 2 track level is monitored by a track-mounted shadow board 13 between light transmitter/receivers 11, 12. Lateral alignment is monitored by measuring the horizontal arc heights (at point 12<SP>1</SP>) from short and long chord wires 15 and 16 stretched between trolleys 17-18 and trolleys 17-21, the track 5 being shifted sideways until the arc heights are equal.

A moulding press is driven by a motor having a three-phase main winding supplied through two groups of thyristors for reversible operation, and a retarding winding which is energized through a bridge rectifier network comprising a pair of thyristors and a pair of diodes. At the beginning of a programmed cycle of operations, the ram is driven downwardly from an intermediate position at a controlled speed. The main winding is de-energized when the ram reaches a lower position and the retarding winding is energized in a controlled manner so that ram engages the moulding material with a desired force. After a predetermined period, the retarding winding is de-energized and the ram is returned towards the intermediate position at full speed. At this position the upward drive is halted and the ram is retarded for a set period. The ram is then reversed for a second impacting operation, the second impact being stronger than the first. Thereafter, the ram is raised to an upper position to provide a longer stroke, and is driven downwardly without being retarded as it approaches the lower position so as to provide a heavy impact force.
