Title: Improvements in or relating to testing the hardness of water
IPC: G01N21/82
Filed: 1953-11-06
Abstract: 756,961. Testing water hardness photoelectrically. BOBY & CO., Ltd., W., and MAZIJK, A. P. VAN. Nov. 5, 1954 [Nov. 6, 1953], No. 30837/53. Class 40 (3). In apparatus for testing the hardness of water the water is caused to flow along a passage at the entrance to which a small dose of soap solution is injected, a beam of light projected lengthways of the passage into a photo-cell being used to give a signal representative of the turbidity the arrangement being that the passage is washed out by the continuing flow of water. As shown, the effluent from the baseexchange bed is fed to a constant head arrangement 13 and through a regulating cock 26 to a housing 22 at the end of test chamber 19. The water enters the housing tangentially at 26, flows through it and leaves through passage 27. Windows 23 close the ends, a light source 32 being situated beyond one end and a photo-cell 33 beyond the other. Wipers 24 actuated from outside the end housings are provided. The soap solution is fed into the water supply pipe 30 from a large shallow tank 28 by electromagnetic operation of a valve 31 which pinches a rubber pipe supplying the soap solution. A motor is provided controlling cams which allow soap to enter at 10-minute intervals and control the regeneration of the bed if the liquid is cloudy. The Specification mentions that if coloured water is used a balancing cylinder and photo-cell are desirable if a second regenerator is being used. Operation.-Closure of main switch 42 energizes motor 36 driving the timing cams 37, 46, 54, 55, 74 and 96 and lighting lamp 32. Cam 37 controls the admission of soap solution by valves 97, 98. A corresponding pair may be actuated alternately by means of cam-operated change-over switch 96 if a second regenerator is being used. The photo-cell output is fed to amplifier unit 50 operating a milliammeter and a relay coil 51 if the water is sufficiently hard. Since the photo-cell output increases gradually, to prevent irregular operation of the relay, cam 46 operates a switch in series with the relay contacts for a small period in the operating cycle only. If the photo-cell output is sufficiently large relay 52 closes its contacts and is locked for a period of two minutes by cam-operated switch 53. During this period cam 55 closes one or other of switches 56, 57, each associated with one of a pair of base exchange units, and one of a pair of relays 58, 59. Assume switch 57 to be closed. A relay 68 is energized through contact of relay 52, switch 57 and contact of relay 58, so that motor 69 is energized. Motor 69 runs and closes the inlet and outlet valves of the softening unit while cam 72 completes the circuit of relay 58 which stops the motor. Shortly after, cam 54 deenergizes relay 52. A few seconds later cam 74 closes a contact 75 for a few seconds, thus energizing relay 76, which locks. Motor 69 thus restarts and runs until its cams have operated all the valves necessary to effect regeneration. Finally the motor circuit is opened by cam 77 and it stops.
