| Y4430 To RHC {R. H. Coverley - Production Engineer} K. {Mr Kilner} E.O. Aq. EXPERIMENTAL BY {R.W. Bailey - Chief Engineer} /WER3/EF28. 11. 21. 4430 X. 2485 - "GOSHAWK" 11. CONDENSER - SECTION 8130. We are now issuing to you detail drawings to enable you to make up another Condenser to a design which allows increased depth of active Condenser Plates. This is an alternative to that previously issued to L.O.P. D. {John DeLooze - Company Secretary} 50087. Please receive herewith one blue print of each of the following drawings, will TB., also receive one set. D. {John DeLooze - Company Secretary} 50522 Condenser Base 1 off. D. {John DeLooze - Company Secretary} 50523 Guide Pin for Condenser Plates 2 off. D. {John DeLooze - Company Secretary} 50524 Condenser Insulation 43¾ off. D. {John DeLooze - Company Secretary} 50525 Condenser Plate L.H. 215 off. D. {John DeLooze - Company Secretary} 50526 " " R.H. 215 off. D. {John DeLooze - Company Secretary} 50527 Condenser Top 1 off. D. {John DeLooze - Company Secretary} 50529 L.O.P. D. {John DeLooze - Company Secretary} 50529 General Arrgt. In addition to the above parts and stock parts called for on the L.O.P., the following details will also be required:- D. {John DeLooze - Company Secretary} 50528 Distance Piece 1 off. K. {Mr Kilner} 4301 5 B.A. Standard Hex.Lock Nut S/M - 1 off. (To be nickel plated). K. {Mr Kilner} 1705 5 B.A. Cheese Head Screw - 1 off. If this design of Condenser is ever standardised then the few parts quoted above would be added to the L.O.P. for the Distributor and therefore are not called for on the Condenser L.O.P. Regarding D. {John DeLooze - Company Secretary} 50522 Condenser Base we suggest that for the first experimental model this detail instead of being produced in Bakelite as a moulding could be made in Ebonite or out out of a block of Continental Bakelite, and thus save the time required for making the Dies for moulding. Regarding D. {John DeLooze - Company Secretary} 50525/6 Condenser Plates it should be noted that the legs have been left long and a hole punched in same at the end, this is to enable the Tinfoils to be more readily built up by locating on two pins instead of as previously on one. The superfluous length of tinfoil would of course be cut off after the Condenser has been built up. BY {R.W. Bailey - Chief Engineer} /WER. WER [STAMPED]: RECEIVED 24 APR 1921 | ||
