| To R.{Sir Henry Royce} from EFC. c. Sg.{Arthur F. Sidgreaves - MD} c. PN.{Mr Northey} c. Wor.{Arthur Wormald - General Works Manager} X1589 EFC3/AM.1.30. X.1589. RECTIFIER SET FOR CAR BATTERIES. We have now obtained from the Westinghouse Brake & Saxby Signal Co. a quotation for a Rectifier Set as referred to in our EFC2/AM.16.12.29. except that it was thought more suitable to enquire the price of the next size smaller than the one therein referred to. The quotation reads as follows :- "For our Westinghouse Metal Rectifier Set style RP-10-F to give an output of 12/14 volts 6 amps. from 200 volts 50 cycles single phase A.C. the sum of, THIRTEEN POUNDS. (£13. 0. 0.) This set will be as illustrated on page 10 of our brochure D.P.11 enclosed herewith in duplicate and will consist of a transformer fitted with an adjustable core for control of current, and Rectifier Units protected by a heavy gauge perforated sheet metal case, the whole being mounted on an angle iron frame and arranged for wall mounting. A bakelite panel is provided, and carries A.C. and D.C. terminals and fuses. main switch and moving coil D.C. ammeter. The above mentioned price is strictly nett and provides for delivery your address, which we anticipate could be effected in about 3-4 weeks." We are sending with PN{Mr Northey}'s copy of this note a copy of the manufacturers brochure D.P.11. for his information. In accordance with your RL/M16.12.29.we propose in due course and subject to your approval to place an order for one of these sets. It would be a great convenience here to be able to charge a battery in position on a car thus saving work of two removals and replacements. EFC. | ||
