Abstract: METHOD OF UNDERGROUND GASIFICATION OF A         SERIES OF GENTLY DIPPING AND INCLINED                      COAL SEAMS                         Abstract A method of underground gasification of a series of gently dipping and inclined coal seams comprises the steps of determining the depth of  occurrence and the thickness of each coal seam in said series thereof, opening the seams by drilling operating wells, inter-connecting them within the given seam, setting the coal afire, and gasifying the seams. A safe mining depth is determined for each coal seam in the series and said series of the seams is gasified upwards when a rock thickness therebetween exceeds a safe mining depth for the underlying seam and downwards when the rock thickness therebetween exceeds said safe depth, a firing boundary of the underlying seam being shifted towards a coal pillar by an amount equal to or greater than a first spacing of rock caving in the roof of a gasified layer.

Abstract: ABSTRACT           A calorie counter for persons wishing to control their weight has a housing with a base and a transparent cover rotatably mounted to the base.  An opaque partition is located in the housing parallel to the cover and spaced apart therefrom.          This partition has three circular calorie counting scales provided thereon.  The partition consists of an inner disk having first and second calorie counting scales and an annular disk which is an outward extension of the inner disk.  The annular disk is rotatable and protrudes through a side wall of the base at one location.  Two line indicators are provided by two transparent disks located between the cover and the annular partition.  The first indicator points to the number of calories contained in a food item while the second indicator points to the total number of calories consumed by the user during a set time period.  A gear mechanism operated by a thumb wheel operates both of the indicator disks at the same time.

The framework includes a wall abutment section and a ladder support section projecting therefrom.  The platform is carried by the framework and is pivotally attached to either the wall abutment section or the ladder support section of the framework.  Connected to the platform and carried by the framework is a latch which engages at least one of the ladder sections to maintain the ladder sections in a collapsed condition.  The application of weight to the platform allows the ladder sections to assume an extended condition.  In one embodiment of the invention the plurality of ladder sections in their extended condition lock to form a rigid escape ladder.  The use of the latch in cooperation with the platform provides for automatic quick and simple extension of the ladder sections to form an escape ladder.
