Abstract: A fuel injection nozzle of the inwardly opening type including a valve member surrounded by a sleeve, the valve member and sleeve both being movable by fuel under pressure supplied to an inlet. The valve member is biased into engagement with a seating by the action of a spring which acts on the valve member through a spring abutment. The sleeve acts on the spring abutment through an annular intermediate member. The extent of movement of the sleeve is limited by the engagement of the intermediate member with a stop surface and the extent of movement of the valve member is limited by the engagement of a step on the valve member with the intermediate member.

Abstract: A rotary distributor type fuel injection pump has a pair of angularly adjustable stop rings having shaped internal surfaces which can engage with the cam followers of the pump to limit the outward movement of the pump plungers. The stop rings are interconnected by a saddle member and a spring biases the saddle member into engagement with a stop. The stop which may be adjustable determines the normal maximum amount of fuel which can be supplied by the pump. For starting purposes the stop rings are moved to an excess fuel position which is achieved by a pin engaged in a slot in one of the rings. The pin is spring biased to move the one end and hence the other ring to an excess fuel position and is coupled to a fluid pressure operable piston which when the associated engine is started is moved by fluid pressure to move the pin to allow the spring to move the saddle member and stop into engagement with the stop.

Abstract: A fuel pumping apparatus for supplying fuel to an engine has a high pressure pump which includes a component movable to determine the maximum amount of fuel which can be supplied to the engine. The component is biased by a spring to a minimum fuel position and to adjust the setting of the component there is provided a three armed lever one arm of which is coupled to the component. The other two arms are coupled to engine operating parameter responsive devices. In the example the device is a piston which is spring loaded and is responsive to the output pressure of a low pressure fuel pump and the device includes a diaphragm which is subjected to the air inlet manifold pressure.

Abstract: Coal is processed first through a moving bed reactor and then through a fixed bed reactor. Hot carbonized coal char is fed from the first stage reactor to the second stage reactor via a lock hopper and gas is taken off from the reactors either in separate streams or in a common stream.

Abstract: A process is described for separating soluble copper and manganese catalysts from organic saturated monocarboxylic acids having 3 to 9 carbon atoms by precipitating the copper and manganese as oxalates.

Abstract: A process for producing formcoke composed of char and selected binders comprising process steps in which non-oxidative thermal carbonization is employed.

Abstract: Sulfonic acid catalysts useful in, for example, esterification reactions and which contain an admixture of any of several phosphorus compounds including specifically ortho-phosphoric acid are much less corrosive toward metal processing equipment than are sulfonic acid catalysts without the phosphoric admixture.
