NICHOLSON MAXES Freeze-Proof Steam Traps ^ ior every Plant Use Becauso they drain eomplotoly when cold, these four lypq* of Nicholson steam traps are positively freeze-proof. Con be freely installed out- doors. Universally recommended for use in lines which need not be In continuous use during cold weather, be* cause they are freeze*proof and because their 2 to 6 times overoge drolnogo ca pacity results in minimum heat*up time. The non . air - binding feature of Nicholson traps also notably facilitates heat fvpp A transfer in severe weothor. Types for every plant use. Size 14" to 2"; pressures to 250 lbs.

TTieae basic standards are plenned to govern specifically the installation of consumer-owned gas piping, both In buildings and between buildings extend ing from the utility company gas meter outlet to the Inlet connections of ap pliances; and the Installation of con sumer-owned gas utilizing equipment. It is proposed to eover piping systems lor industrial installations at any pres sure and for all other non-residential installations at operating pressures (n excess of Vk pal gage, installation and testing of these eyslcms for fuel gases such as natural gas, manufactured gas, liquefied petroleum gss-oir mixtures or mixtures of any of these types, but not cover systems for undiluted liquefied petroleum goa or those handling gas-air mixtures within the limits of Inflamma bility. Protective atmosphere gases are not covered. Port I outlines the proper procedure In eaeo of any emergency end or neces sity for doing work on tho gos service pipe, the gas company's meter, eio--that is, on any part of the service Installation containing unmeasured gas. This part also gives general precautionary advice with reference to shutting off gvs piping systems to make now connections, repeir leeks, eta With reference to pis leaks. It aeems almost needless to men tion here that cheeks for ges leakage should be made by brushing a soap and water solution on the suspected areas, that artificial illumination used in such searches should be restricted to flash lights or fixed electric lights controlled by switches remote from the area of leakage and that smoking, open flames, lanterns, or other sources of ignition should not bo permitted when working on piping which conlolns, or has con tained, gas.

BltBepvllla, Saalb Carolina Coal is fed to douhle-Ies, horizontal run of L-lype REDLEK Conveyor through track hopper or yard stor age hopper. The fl-in. ItEDLER handles minus 3* coal at a rate of 35 tons per hour, carrying it hori zontally for 47 feet, then up 56 feet to the top of the boiler house. Here It feeds a 44-foot slope REDLEn, which, in turn, feeds o horizontal REDLEK charging into four coal hoppers. Selective discharge is con- by rack and pinion gates. Y8MG glem cut Construction Cost by Moving Coal Over the Roof This S-A FIEDLER Conveying Syslem utilizes "dead*1 rooftop space for a high capacity, multiple-discharge feed line for stoker hoppers. Construction costs were minimum, because the enclosed REDLEK needs no shelter from the weather. Hopper capacity is greater, since llierc arc no conveyors inside the building to take up headroom. And, of course, spotless-clcan, dust-freo REDLEK handling is a big advantage for this finishing plant. Iloro, as usual, S-A engineering goes beyond mere, provision of "adequate" conveying. It capitalizes on a complete line of efficient bulk handling equipment-- a line so complete that there is a conveyor or combina tion to meet every problem of plant layout, including yours.
