摘要:
A method for overpressure control in a hydraulic system having multiple hydraulic pumps, with each hydraulic pump being connected by a respective hydraulic circuit for actuating a single respective hydraulic actuator, includes actuating a first variable displacement hydraulic pump, the first hydraulic pump being fluidly linked by a first hydraulic circuit to a first hydraulic actuator for powering the first hydraulic actuator. Upon detecting a pressure that exceeds a predetermined threshold pressure, the flow rate of the first hydraulic pump is electronically modified to a second flow rate lower than the first flow rate whereby the pressure in the first hydraulic circuit is reduced to a pressure that is below the predetermined threshold pressure.

A doctor assembly for a pad printing system includes a body and a doctor blade. The body has an outer surface and an opposite inner surface that defines a passageway through the body. The inner surface engages a removable pre-filled ink cup to secure the ink cup to the body. The inner surface directs ink from the ink cup through the passageway toward an ink-receiving surface of a cliché device. The doctor blade is coupled with the body and engages the cliché device. The doctor blade wipes the ink along the cliché device as the body laterally moves relative to the cliché device. The doctor blade is coupled with the body such that the doctor blade is laterally spaced apart from the inner surface of the body.

摘要:
An answer engine determines an entity related to a query from a user in a system designed for computation, search, or other activities involving the processing of queries. The system determines whether an entity page for the entity is stored in an answers database and, if so, retrieves and displays the stored entity page. If there is no stored entity page for the entity, the answer engine generates and displays an answer to the query and may optionally store the answer as an entity page. Additionally, the answer engine may pre-generate and store entity pages according to algorithmic variation of received queries and/or according to information received from external sources.

Compounds of the general formula: ##STR1## wherein X represents a halogen atom or a trifluoromethyl group; R.sup.1 represents a hydrogen atom or a lower alkyl group and Het represents an optionally substituted C-attached 5-7 membered aromatic heterocyclic ring which ring contains one or more heteroatoms selected from O, N and S and optionally carries a fused ring and where an acidic or basic group is present, the salts thereof have been found to possess excellent metaphase arresting ability and are of use in combating abnormal cell proliferation. Thus a knowledge of the cell division cycles of the normal and abnormal cells enables a cytotoxic drug to be administered while the abnormal cells are in a phase susceptible to attack and while the normal cells are in a non-susceptible phase.The compounds of the invention are prepared by alkylation, deprotection of a protected keto group, oxidation or electrophilic halogenation.

摘要:
A system (10) for tracking warranties and other time critical contracts. The system (10) includes a data store (12) for storing at least authentication information for authenticating a user to the system and contract information including start date and end date of the contract being tracked. The system (10) also includes a processor (13) adapted to access the data store and from the information made available in the data store, determining one or dates regarding time critical contracts, and for directing communications with a user via a communications module (14) which is adapted to send and receive information to and from a user's networked device including a mobile telephone (16) or a computer (18) and where the information sent to the device includes at least, an alert reminding the user that the contract is about to expire, in advance of the end date of a contract being tracked.
