Title: Production of Fresh Water from Salt Water Aboard Watercraft
Inventor: MCINTYRE E LOWE JR
IPC: C02F1/10
Filed: 1967-04-13
Abstract: 1,177,819. Distillation of water on watercraft; separating water droplets from air. E. L. McINTYRE. 13 April, 1967, No. 17021/67. Headings BIB and BIT. Fresh water is produced from salt water on watercraft driven by an I.C. engine by using a stream of the salt water as coolant for the engine, introducing the heated salt water through inlet W1 into a substantially closed vessel wherein the water is sprayed through nozzle 47 into a circulating flow of air which has bubbled up through a layer L of hot salt water in the bottom of the vessel, so that a mixture of air and water-vapour flows through mist eliminator 27 and down over cooled coil 15 where the water-vapour condenses, and withdrawing the condensate (i.e. fresh water) from the vessel through conduit 20 and outlet F. The cooled air passes through mist eliminator 28 and is recirculated by fan 13, driven by electric motor 14, through an annular passageway between the outer wall of the vessel and the partition 18 to below the surface of the layer L of hot salt water. Some of this salt water is returned to the engine cooling-system through outlet WR, and the excess is discharged to waste through overflow 23. Coil 15 is disposed in an annular passageway between partitions 16 and 19. The vessel is vented to the atmosphere by pipe 24. Seawater to be distilled is pumped through coil 15 and then through a heat exchanger which is also traversed by fresh water which circulates through the cooling-jacket of the I.C. engine. In a modification, the engine coolant may be passed through a coil in the base of the evaporator/ condenser vessel; and the coil 15 is replaced by nozzles for sprays of cool fresh water. The body and partitions of the vessel may be made of glass-fibre reinforced polyester. The mist eliminators 27, 28 may be made of open-cell polyurethane foam having a porosity such that 97% of the volume is air-space.

Patent GB-356162-A (GB)
Title: Improvements in or relating to indicating or display devices
IPC: G09F11/295
Filed: 1930-06-02
Abstract: 356,162. Electric signalling systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, and SAXBY, R. N., 36, Millersdale Road, Mossley Hill, both in Liverpool. June 2, 1930, No. 17037. [Class 40 (i).] An indicator, of the thermometer type, and described in connection with totalizators, comprises an indicating member controlling by its movements the position of a rotary switch which in turn stops the member at the desired point. As described in Specification 331,500, [Class 40 (i), Electric signalling systems &c.], the total to be indicated is represented by the marking of a particular lead and these leads are wired to the banks of a rotary switch CS. The wipers 6 .. 11 of this switch are connected by a common line 19 with a magnet 28 controlling by its armature 27 the rotations of a shaft 30 carrying a sprocket wheel 5 adapted to permit ascent of a weight-influenced band 1 bearing a pointer. The band normally occupies a position well below zero, but when lead 14 is earthed, to start the indicator in action, relay A closes contact a2 and breaks the earth circuit through contacts a1 .. a6. The magnet 28 is thus de-energized and allows the pinion 31 and therefore the shaft 30 to rotate, and the indicator to ascend. As the shaft rotates, a contact 26 sends impulses through a line 20 to operate a relay P and cause corresponding stepping of the switch. When wiper 6 reaches the nought lead U, earthed to denote that the particular horse is a runner, earth potential is thus again applied to line 19 to operate the magnet and stop the movement ot the indicator. Similarly as bets are registered the indicator advances and in turn steps the switch until the marked lead is reached and the magnet again energized to stop the indicator. As the total passes from denomination to denomination, the lower unwanted denominations are cut out by the relays B, C, D one after the other so that only the first digit of the total is indicated. A governor 23 steadies the movement of the band 1 and this may be restored to normal position by raising the weight 3, the chain 4 being removed from the sprocket wheel 5 during this operation, or a freewheel connection between wheel 5 and shaft 30 being interposed to prevent closure of contacts 24, 15. The switch may be zeroized by operation of a key R to apply earth potential to the homing banks of the wipers 12, 13.

Abstract: A strip of synthetic linear polyamide is formed by feeding molten polyamide, by a screw 5, between the nip of rollers 10, 11 which are cooled by water in a bath 16.  To prevent the surface of the strip from being spoilt by the cooling water, resiliently mounted flexible wipers 22a remove the water from the rollers <PICT:0662013/IV (a)/1> at a point beyond their point of contact with the water and before the entrance nip.  The wipers may be made of a synthetic linear polyamide or polytetrafluoroethylene.  The water is circulated through inlet and outlet pipes 20, 21.  The outlet pipe 21 may have an elbow which may be rotated to allow the level of the water in the bath to be varied.  The material may be melted by electric heaters 8. Take-off rollers 19 maintain a slight tension on the strip, but they also allow the strip to slip, when necessary.
