Patent number: 9718744Abstract: Disclosed is a hydroalkylation process in which the hydroalkylation catalyst is activated in the presence of a flowing fluid comprising hydrogen and a condensable agent. The presence of the condensable agent enables fast, effective activation of the hydroalkylation catalyst precursor in a cost-effective manner. It also yields superior catalyst performance.Type: GrantFiled: September 26, 2014Date of Patent: August 1, 2017Assignee: ExxonMobil Chemical Patents Inc.Inventors: Gabor Kiss, Thomas E.

Publication number: 20090106772Abstract: The invention concerns a method, computing device, data processing system and computer program product for ensuring correct processing of data according to various system states. The system includes a first data processing module having a state control unit which blocks reception of data on input channels where a state message indicating a change from an old state to a new state has been received and sends a loop check message into each loop in a set of data processing loops the module is connected in and for which the old state applies. The state control unit also removes the blocking when for each loop in the set either the loop check message is received in the module or an associated input channel has received the new state and all other input channels have received the new state.Type: ApplicationFiled: October 18, 2007Publication date: April 23, 2009Applicant: OMX Technology ABInventors: Henrik Jarl, Magnus Rosenlund, Johan Eriksson, Thomas E.

Patent number: 4247767Abstract: Apparatus for detecting the position of an object, e.g. for interaction with a computer graphic display, has a number of light emitting diodes in an endless array, and a lesser number of light detecting devices for providing electrical signals in response to momentary and successive energization of the light emitting diodes. The signals are electronically processed to provide cartesian co-ordinates. This apparatus provides high resolution with a minimum number of light detecting devices and enables too large objects and malfunctions to be readily detected.Type: GrantFiled: October 16, 1978Date of Patent: January 27, 1981Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of National DefenceInventors: C.
