Title: DC machine with distributed exciting and compensating windings - uses yoke made from AC machine stator laminations
IPC: H02K3/24
Filed: 1976-06-24
Abstract: The design reduces the cost of compensated D.C machines by employing a single type laiminations to build both yoke and poles, instead of three separate ones. The laminations can thus resemble those of an A.C machine stator and existing lamination types for such a machine can be used. The field (5) and compensating (6) windings fill practically every slot (4) in the yoke. The compensating winding is pref. nearest to the air gap (10). This winding compensates for practically the whole of the armature MMF, therefore the air gap can be narrow. The commutating poles are also eliminated. For enhanced cooling an air duct (7) may inserted in the slots between the windings.

Title: Control system for hydrocarbon hydroconversion processes - monitoring process parameters and regulating hydrogen/hydrocarbon mole ratio
Inventor: MCLAUGHLIN JAMES HERBERT
IPC: C10G49/26
Filed: 1976-07-31
Abstract: The hydrogen/hydrocarbon mole ratio is continuous, hydrogen-consuming, hydrocarbon hydroconversion processes, is controlled by employing analyser to monitor composition characteristics of the charge stock of the liquid reaction effluent and the hydrogen concentration of the vapour phase introduced into the reaction zone, and transmitting representative output signals to comparator/computer means which generate additional comparator output signals which are then utilised in the control system for regulating the H2/hydrocarbon ratio. The technique is applicable to processes in which the reaction zone effluent is separated into liquid and hydrogen-rich vapour phases, a portion of the later being recycled in the reaction zone. The method compensates rapidly for changes in charge stock characteristics and operating parameters and maintains catalyst activity and stability.
