"i?E7act from the Launces-fcon "Daily Telegraph" of 17-bh July 1918 (Yes,:
"To Master Laurence Jensen belongs the first installa'fcion of elec-briLc light, in
the torn of Rail-bon, The Uttle lad vho is on]y 12 years of gge, became
possessed of sone partly spent baUerxes, and with the aid of a parb of an
electric torch, has fi-btcd'the electric light in his bedroom, -the young lad
having so nianip-ula-bed his wires -that -fche light can be sw.-bched on and off as
easily and as quicld-y as an ordinary fix-fcure'1
That li-fctle lad is now, of course, tha-b elflerly gent V&7LJ hij

An "Add on" Produc-fc Detector b <T Browi YI^7BJ'.
Whils-t a diode detector can demodulate SSB quite sa-bisfac-fcorily 3^ -fche
BFO injec-bion is high enough, -fcheproduc-fc de-fcectior -will make a far better job^of
it when the usual BFO is used. G. W» reception is also improved as the produc-fc
detec-bor mil no-fc "block up" on s-brong signals.
The unit rescribed vas designed -bo fit in an exi.s'tin.g set which was
already crammed full and therefore uses the Eiininun of parts. It. will demodulate
A. M, (with the BFO off) but -this does not matter in practice.

If a 3 pole sid. tch is used -the 3rd. pole can be used to disable the AVG
although it should be OK -bo use AVG particularly if -the time 1 constant Is long,
This a-wi-tch replaces the existing A. M. noise limi-ber "In/Out1 one. The -valve
should be located near the output I. F. -fcransfomer and HFO valve. The
secondaxy of the I»F, ou-fcpu-b -bransfomer will need re-bum. ng· Any other •fcwLn
iriode- con be used without changing values, A 68N7 or 12AU7 would probably
be be-b-ber than the 6J6,
