Negative Plate
Communication being established, the lead is forced by the
The mold being released; after cooling sufficiently, is opened After scraping and trimming, the Plate is "Formed".
That is to say, the plate is put into a bath of Zinc chloride,
This eliminates the Chlorine in the pastilles, leaving
After this, the plate is made the cathode It is known as the Chlorine Plate. |
The Positive Plate
The Positive Plate is essentially, a number of Rosettes, circular,
It is necessary to hold them in place, which is
The Rosettes, are intended to be subject, to chemical change, They are therefore, the active element of the plate.
The Grid is not intended to be subject The Process of Manufacture
The Grid is cast, in an iron mold, the lead being forced in under
The Rosettes, are made in a machine, from a take
In passing through the machine, it is corrugated
The corrugations, have the effect of making the rosette very
They are then entered, into the holes in the grid |
The Positive PlateForming the Plate
The process is exactly the same as in the old Plante Process
Also instead of using the negative plate a dummy plate is
The positive plate is put into a bath of sulfuric acid
The action of the battery thus formed is to
This form of positive plate is called the Manchester |
Exciting Fluid
The exciting fluid is of Sulfuric acid diluted with pure Freshwater is a poor conductor of electricity.
If however a little acid is added it improves the conductivity
The solution then is at the maximum conductivity when it is
The solution must also be free from iron & from nitric acid.
The maximum capacity of the plate is 2.8 volts
per cell or element. The Battery must not be discharged |
Instructions for setting up and using the
|
Salt water is fatal to these Batteries & must be carefully |
(11) If a battery is to remain idle a long time, it should first be
Then start discharging the battery at its normal rate, which will only
It is very essential that the voltage of each cell, should be Read these instructions carefully. If any further information is desired, communicate with the company. |
Storage Battery Design
As a preliminary it is necessary to understand, that the hourly output
Required a Storage Battery capable of furnishing a Power IHP The current A
The total voltage of the battery is determined by considerations of Therefore A = IHP x 746; amperes. (1) V Surface S of one element
One square foot of element, will yield a normal output of 44.24 ampere S = (IHP x 746) h (2) ( V x 44.24) Number of elements n
The individual voltage of each element is (v) and the total voltage v 2.25 Weights G The weight of the element is 11 pounds, per square foot, consequently for one element G = 44(IHP x 746) h pounds (4) (V x 44.24) while for V/n elements G = 82.439(IHP) h G = 44 (IHP x 746) h (5) ( n x 44.24 ) including electrolyte & lead lined vessels G = 172.37(IHP) h G = 20 (IHP x 746) h pounds (6) ( n x 44.24 ) Cost $
This is a subject of various aspects, but at 75/8 cents per $ = (IHP x 746 x 0.75) h dollars for one cell only ( v x 8 ) For V/n cells and adding 12 per cent for lead lined tanks and the electrolyte Then the cost will be $ = 1.12( IHP x 746 x 0.75) h = $ = 34.813(IHP) h ( v x 8 ) In the Holland v = 2.066+ volts Roughly speaking the cost per IHP is 300 dollars for 8 hours normal rate Lights In casting about to find the number of lights which can be maintained; in the absence of better information reckon 10, 16 candle lamps to one IHP.
Therefore v = 2.25
