ARGUMENTS Hero's l/e place fo unload your gripes to editors, roanufocf * and fellow engineers u,<" See how this NMtrap Rotatory Wonder Solves Farm Problems British newsmen describe this lifesize, rustic machine as a "joyous end improbable attempt to achieve the im possible.'' And no wonder. It's Rowland Emett's ``Hogmuddle Rotatory Nlggler and Fidgeter," built by J E Slater, Ltd, Kfbworth, Leicester, for Petters, Ltd, Staines, Middlesex. Emelt, who is wellknown both in England and the U. S. for bis erlislic genius, is the self-styled chairman of Improbable Railways. Emelt claims that this complicated machine wilt do all the work of a farm --from inducing eggs to filling out government forms. Hero ore some of its features, as reported by the Driliah raogatine, The Engineer. Immediately behind the pylon sup porting the 10-hp engine is a concur rent 4-stage baler. Next to it, an egginducer with X-ray attachment encour ages egg laying by tbe resident hen. A rotary stook1 drier and setter and sn aeromechanic's seat complete the first section of the niggler and fidgeter. A hogmuddle free-Row arch joins the machine'* two aectloni, and allot otherwise b disturbed by the le_ n"'jjjjhjjtj;ji: the machine. Above the arch u a c j-, liined hedge trimmer and gentlemen*/! hairdresser, consisting mainly of thf pairs of spring-operated scissors. The secondary section conlsi wursle3 digger, scrubber and poliibV embracing the lully automatic hegV muddle carrot rejector. Wursle* st dug by the 4-fork scrahbler, which to* moves them from ihe esrth and impalu them on prongs of the large fer ' wheel. Should a carrot inadvertently dug, all rotary movement stops. T carrot is advanced slowly toward i rejector-trap, whioh leapt forward receive it. Trap passes the cirroi to vihrotory corrol-fuddler, which rem! ders the csrrol entirely harmless, etf cept for the subsequent carrot-puree. There ia a control office, devised ft^> taking care of most of the farm paper`S work. Covernment forms moving imsrt-ij ly on an endless belt are filled ln,( stamped and carefully disposed of qu'its^ painlessly as the machine is working,^, leaving ihe gentleman-farmer entirely." freo to enjoy the revolving featherbed., Beneath llte bed a rotary haystack ii.j fed by a reversible hay lift that, forms' a useful method of supplying the fanner with refreshment. ladles greater volume in less time Yet it's small--gives you maximum capacity per dollar cost new SARCO Inverted bucket trap Hwith CAMLIFT valve mechanism Cwtt Ml n tat- As bueUi sink* CAMLIFT mechanism pro- , A vjdei ihe poweiful crowbar action needed to M open Urge valve against steam pressure.

That means you get more for your steam trap dollar. Do You Advocate Fuel-Oil Additive!? The article, "18 Diesel Q and A," May power, mentions use of lube oils with additives to fight aullur. But it does not mention using odditivea in the fuel directly. Do you advocate their use, and have you ever tested any? There are several on the market over here, ond 1 understand that at least two Cerman firms propose their use. His any reader had experience with using additives directly in the fuel, and what have been the results? R C Mueller St. Nom la Breteche, France We Don't Need Earth-Leakage Trlpi Rf.cardinc this question o! grounding techniques, September "Arguments," I was glad to note Whitaker's pertinent statement, "Our rules for grounding portable equipment ... are based on conditions existing in (be U. S." From 1935 to 1938, I wos in India where the earth-leakage breaker was being applied to local bungalow instal lations, mostly with only one SO-cycle oc eircuit.'These units operated at 22 v 2 v above ground with a 200-ohm resistance, and at less than 6S v with an 800-ohm resistance. The breaker* were installed because usiog them was less expensive than arguing intermin ably with an oiflhority. But the manufacturers used no spe cial grounding devices for portable tools, and there were no serious results. I presume Hardy's system is nomin ally at 250 v, line to neutral. This re quires care where local labor is con-. corned, since fatalities at less than 220 v were not uncommon during my so journ in Indio. During a 5-year period 1 kept a care ful record of troubles for a group of public utilities in the U. S., extend- ing Irom Maine to Florida and as far-'ia west as Michigan. There were only.] two occasions where poor grounding caused serious results. if U. S. technique "is way behind current British practice,'' one wooden TjvSj why the additional equipment woold 'ijwf be justified here. A separate earth- T* leakage trip would be required for caeb portable-device circuit to looalite the '* fault area, while with one grounded lead a fault is at once apparent. C 0 vonDannf.ndgrc Brooklyn, ff. Y. Right You Are ... In "Hard Surfacing," March, psg* 115, Fig. 9 states that magnetic bio* happens with ac. In welding shop I learned that "arc blow" occurs only with dc. What'i the right answer? J S Miller Seattle, IFash. Editor's note: You are right. F* meant to say '7/ you have arc blaer. correct by using oc." The Sarco Camli/t valve mechanism makes this possible. It provides the powerful force needed to open the Unusually large valve without a corresponding increase in trap sixe. , When eam pressure Is overcome CAMLIFT mechanism drops to limit of slot, allowing . rapid and free discharge of condensate.
