Abstract: AUTOMATIC SHUT-OFF NOZZLE HAVING CONTROLLED VENTURI  Abstract of the Disclosure An automatic shut-off nozzle has a venturi effect, which causes automatic shut off of the liquid flow through the nozzle body by causing a main poppet valve to be closed when the tank is filled, created by two aligned passages of different diameters in either the resiliently biased bleeder poppet valve, which opens in response to the pressure of the fluid flowing through the nozzle body, or the seat ring for the bleeder poppet valve.  The smaller diameter passage has the liquid enter its inlet with the liquid exiting through the outlet of the larger diameter passage with the larger diameter passage also communicating with the vacuum chamber in which the vacuum is increased by the venturi when the tank is filled to cause automatic closing of the main poppet valve in the nozzle body.

Abstract: A B S T R A C T   The present invention relates to a nozzle plate for ink recording devices.  According to this invention, outlet openings, aligned in accordance with the desired direction of flight of the ink droplets, are provided with an ink inlet zone adapted to initially centre the writing fluid and with an accelerating zone which is concentrically disposed with respect to the inlet zone.  The present invention is applicable to ink writing mechanisms for office, data- or teletype machines.  The direction of flight of the ink drop-lets is improved and satellite droplets form much less frequently than in prior art devices.  Also, lower operating voltages may be used on the drive elements.

Abstract: FLOW AMPLIFIER VALVE ASSEMBLY            Abstract of the Disclosure A vehicle vacuum operated road speed control system has a flow amplifier valve in the circuit.  The system uses a very low flow controlled by a system control valve and applied to the amplifier valve.  The amplifier valve receives vacuum directly from a vacuum source and provides an output to the vehicle road speed control servomotor which is proportional to the control flow but is at a much higher flow level.  This leads to the improved system performance.

Abstract: ABSTRACT OF THE DISCLOSURE    A process for calcining green coke obtained by a delayed coking process in at least three stages of heating furnaces which are connected in series and the control of the temperature and the adjustment of the atmosphere in each furnace can be independently. carried out, which process comprises carrying out, in the respective furnaces in the indicated order,the steps of : a) evaporating the water contained in the green coke, and drying and preheating the coke; b) distilling off the volatile matter from the dried coke, and preliminarily calcining the coke; and c) burning the volatile matter from the step b), and calcining the coke, the coke from the step b), after being once cooled, be-ing introduced into the step c).     Because each furnace can be controlled independent-ly from the other furnaces in the above described pro-cess, it is possible to produce high-grade coke without process difficulties such as the loss of the coke by combustion and the formation of coke ring.  The inter-mediate cooling between the steps b) and c) is effec-tive in further improving the quality, especially the coefficient of thermal expansion and the true density, of the product coke.  The heat for reheating the once-cooled coke is given by the combustion heat of the vola-tile matter from the step b).
