Abstract: A compact endothermic catalytic reaction apparatus for converting hydrocarbon feedstock and methanol to useful gases, such as hydrogen and carbon monoxide, comprising a tubular endothermic catalytic reactor, a radiant combustion chamber and an annular convection section. Thus tubular endothermic catalytic reactor receives radiant energy from a metal fiber burner that is disposed within the radiant combustion chamber. Combustion products from the radiant chamber enter an annular convection section wherein heat is transferred by forced convection to the tubular endothermic catalytic reactor. The combination of radiant and convective heat transfer results in a compact design of high thermal efficiency.

Abstract: Apparatus for use in controlling vertical movement of a first weight, comprises a first element rotatable in one direction about an axis and blocked against rotation in the opposite rotary direction; a second element acting as a guide; a control weight; and lines supporting the first weight and control weight by the elements, and including a first line wrapping about the first element and a second line entraining the second element, whereby changes in force exertion on the control weight determine alternative existence of a first mode of operation wherein line slippage relative to the first element allows the first weight to descend, and a second mode of operation wherein line non-slippage relative to the first element thereby blocks descending of the first weight. In addition, the control weight is usable to exert force acting to remove slack from the second line, which is important for safety reasons, where the apparatus is used for climbing. Governor, hoist and other safety elements may be employed.
