A WIRELESS WONDER.

S-. 0.5. THAT RINGS A BELL. ; LONDON, Jan. ;6. The first ileiiioiistratieii of a new’ wireless instrument, enabling the o]_.)—'i erator in‘ a Ship in -:li:.'.':'.‘e:::s to ring! loud alarm bells in all vessels or sta-I tiolls within wireless range, was given ' at the Marconi works, Clenlnsf:ml,‘ Essex, yesterday. 1 Vvhen the Titanic sank, .-1 vessel; was within twenty mile.;, but the riis-‘ tress signals were not lieas.-xl owing to; the operator being in bed. ‘ It is necessary for ships to carry a special automatic transmitter and receiver, and when an enieigenrrj arises ‘ the operator presses the key of the traiisniitter, and in the fraction of :1 minute, a signal of Mon:-5: :lot:<_ sent at exactly 180 per minute, is 1.-eiiig received by every vessel within range carrying a receiver, and :1 bell is l<€Dt ringing until the operator €:StEil)ll.~‘.h«.?S :1 record wireless communication. For the demonstration, a portable xviri;-less was stationed 30 miles away at Shalt'ord, and upon a pressman telephon—[ ing by wireless the device was DUI!‘ into operation. The dots could be heard by the receiver, and a bell rangg until stopped. The range is not lim-' ited, but depends upon the Do~Wel‘ Of‘ the transmitter. Eighty miles is 0011-’ sidered a usual and a sufficient dis‘ tance. During the war the device‘ was used for exploding miles, et.c.,l and an illustration of its eflicacy was made yesterday, glmpoWdel' being fired by wireless sent from 30 miles ‘away. ‘At the Marconi works at Chelmslford, says the Morning Post, there is a wireless mast 450 ft high, or higher ‘than the cross on the top of St. :Paul‘s. A. short time ago the highest ipart of its was broken by a gale, and ;the question of repairing it arose. sLadders were out of the question. But lthe difficulties did not daunt one of “he workmen, who noticed that the ;mast. was made of quarter-sections bolted together and then fitted one on '}top of the other. He asked, and was given permission to try -his luck. He made himself a belt, at the two ends of which were rings that would slip over the end of the bolts. He also made for each hand a ring that fitted the bolts. Thus equipped, he started to mount on high, the belts being his only means of support. On the first day he swarmed up 200 ft., fitted the tackle, and descended to earth, for it was too cold to proceed lfurther. On the second day he was hoisted up to 200 ft, and then, hand over hand. by means of his rings and ‘bolts, he got to the top of the mast, where he effected the necessary repairs. The last 250 ft. of climbing was done in an hour. And the man. whose name was Post, was 55 years Inf age.
