Abstract: PROCESS FOR MAKING STRONG METALLURGICAL COKE            ABSTRACT OF THE DISCLOSURE         The strength and density of a metallurgical coke produced in a slot coke oven are both increased by replacing at least a part of the normal loose charge in the oven with compacted materials and fragments thereof made from a mix-ture of particularly sized particulate fusible bituminous coal particles, non-fusible particles of a material compatible with the burden of a blast furnace, and water.  During compact-ing the pressure and the moisture content of the mix are such that at least some water is squeezed out of the mix.  The non-fusible materials that are useful include non-coking coals, poorly coking coals, other carbonaceous materials, such as coke breeze, char, anthracite, lignite, and iron oxide-bearing materials, such as iron ores and waste materials from steel plants.  At least a major proportion of the fusible particles and at least a substantial proportion of the non-fusible particles are smaller than about 0.15 mm.          The proportion of fusible to non-fusible particles used is such that such mixture of compacted materials and fragments made from such compacted materials that is charged to the slot coke oven becomes transiently plastic, shrinks and forms a single mass of coke when heated to a coking temperature in the oven, which coke mass is readily dischargeable from such oven.

Abstract: A HYDRAULIC CIRCUIT FOR ACTIVATING A CLUTCH            AND A THROTTLE VALVE USED IN THE CIRCUIT                   Abstract of the Disclosure A hydraulic circuit is disclosed for activating a clutch as well as a throttle valve which is used in the circuit.  The hydraulic circuit includes a hydraulic actuator which is connected to a source of pressurized fluid to alternatively activate the clutch.  Connected between the source of pressurized fluid in the actuator is a control valve and a pressure-responsive throttle valve.  The control valve is basically an on/off valve which controls the flow of fluid to the clutch actuator or from the clutch actuator to a reservoir.          The throttle valve, on the other hand, is arranged in series with the control valve and is responsive to fluid pressure on its downstream side to cause increased throttling of the fluid as the fluid pressure to the actuator increases.  Such a circuit is beneficial in preventing the clutch from snatching as it is being engaged.
