Abstract: This invention relates to a food receptacle and heating apparatus to receive food products therein for receiving, displaying, and maintaining at a proper serving temperature which includes (1) a main container housing; (2) a food support assembly mounted within the main container housing to receive and transfer the food product therein; and (3) an air flow and temperature control assembly to provide for the flow of heated air therethrough. The main container housing includes a generally rectangular box shape basic housing assembly having a top lid member pivotally connected thereto. The food support assembly includes (1) a clean out tray member for receiving debris and food particles thereon; (2) a first inclined screen member to receive the food product thereon about to be removed therefrom; and (3) a second inclined screen member to hold the food product for initial heating before moving downwardly onto the first inclined screen member.

Abstract: This invention is a volatile hydrocarbon detector apparatus to continuously sample methane gas in an oil well drilling mud. The detector apparatus includes 1) a gas sampler assembly to gather the methane gas from the drilling mud; 2) a control module assembly to receive and amplify electrical signals from the gas sampler assembly; and 3) a recorder assembly to receive output electrical signals from the control module assembly.The recorder assembly is of a conventional nature and operates to record on a paper roll the date, time of day and the amount of methane gas present in the drilling mud. The main novelty lies in the gas sampler assembly which includes 1) a hood housing assembly to straddle a flowing channel of drilling mud; 2) a sensing head assembly mounted in the hood housing assembly to measure amount of methane gas therein; and 3) a pump assembly operable to draw inlet air through the sensing head assembly and discharge air into the channel of drilling mud.
