Abstract: The  present  invention  discloses  an  apparatus  and process for coating hollow objects at precise bands within the internal   cavity  of the  object.    The   process   utilizes centrifugal force to apply the fluid to the object.  A probe is moved   from   underneath   the   object   thereby   utilizing gravitational forces to prevent spillage of the material from the probe.  A computer controls the pumping rate, the vertical movement of the probe and the rotational speed of the probe to allow the machine to precisely coat  a  band  on the  internal cavity  of  an  article.   The  computer  controlled  operation eliminates the necessity to waste material.  One application of the invention is  in the coating of the threads of nuts with Teflon.

Granted: 1993-05-11
Abstract: MA988-011 Abstract of the Invention SECURE MANAGEMENT OF KEYS USING CONTROL VECTORS The invention is an apparatus and method for validating that key management functions requested for a cryptographic key by the program have been authorized by the originator of the key. The invention includes a cryptographic facility characterized by a secure boundary through which passes an input path for receiving the cryptographic service requests, cryptographic keys and their associated control vectors, and an output path for providing responses thereto. There can be included within the boundary a cryptographic instruction storage coupled to the input path, a control vector checking unit and a cryptographic processing unit coupled to the instruction storage, and a master key storage coupled to the processing means, for providing a secure location for executing key management functions in response to the received service requests. The cryptographic instruction storage receives over the input path a cryptographic service request for performing a key management function on a cryptographic key. The control vector checking unit has an input coupled to the input path for receiving a control vector associated with the cryptographic key and an input connected to the cryptographic instruction storage, for receiving control signals to initiate checking that the control vector authorizes the key management function which is requested by the cryptographic service request. The control vector checking unit has an authorization output connected to an input of the cryptographic processing means, for signalling that the key management function is authorized, the receipt of which by the cryptographic processing unit initiates the performance of the requested key management function with the cryptographic key. The invention enables the flexible control of many cryptographic key management functions in the generation, distribution and use of cryptographic keys, while maintaining a high security standard.
