Title: Control of Airfuel Ratio in an Automotive Emission Control System
IPC: F02D41/26
Filed: 1979-11-23
Abstract: Closed loop feedback control is applied to a V-8 engine. The exhaust duct from each bank of four cylinders has an oxygen sensor 11, 12 and a three-way catalyst 13, 14. Two carburetters 9, 10 each feed some of the cylinders of one bank and some of the cylinders of the other. Experimental measurements are made of the change in voltage of each of the oxygen sensors produced by given changes in air fuel ratio of each carburetter around stoichiometric air- fuel ratio. A microprocessor stores those values and takes them into account when adjusting each of the carburetters. Engines other than V-8 engines can have a similar system. <IMAGE>
Patent GB-2038510-A (GB)
Title: An adjusting means for an hydraulic machine
IPC: F04B49/00
Filed: 1979-11-26
Abstract: This invention relates to an adjusting means for an hydraulic machine, determining the stroke of the displacement elements. The adjusting means comprise a control sleeve 13 which is displaceable by a setting member 15. In cooperation with a setting piston 18, the sleeve 13 forms a communication from the high pressure side of the hydraulic machine to a pressure chamber 52 or from the latter to a pressure-less space. The stroke of the hydraulic machine is varied according as to whether the pressure chamber is influenced or relieved. A throttle 21 is formed in the connection from the high pressure side to the pressure chamber or from the latter to the pressureless space so that the pressure chamber 52 can be influenced or relieved through the same throttle 21 in different directions whereby blocking of the throttle 21 is prevented. Moreover, a relief valve 55 is provided with the aid of which the adjustment means can be over-ridden when a pressure limit value is exceeded. Moreover, the throttle acts so that, during this procedure, only very little pressure medium can discharge from the adjusting means. <IMAGE>

Patent GB-2071292-A (GB)
Title: Drying Granular Materials
IPC: F26B11/04
Filed: 1980-03-07
Abstract: Seeds are dried by warmed air and optionally cooled in an apparatus comprising two concentric drums rotating on a horizontal axis. The inner drum is the drier and annular space the cooler. The inner drum is lined with longitudinal troughs F which repeatedly pick up and drop the seeds to dry them in air suspension. Seeds are continuously fed into one end of the drier drum, emerging at the other end either through holes into the cooling drum or out of the apparatus and still warm. The airflow can be concurrent or counter-current with the flow of seeds, but when the cooling section is used, counter-current airflow is needed. Cooling is by heat transfer to the drying seeds and by radiation from the outer drum. <IMAGE>
