IPC: H04L69/40
Filed: 1993-02-18
Abstract: Buffers are provided in two elements between which data is to be transferred wherein both buffers are managed solely by the originator of the data transfer.  Only one transfer is required to transmit a message,  and a second transfer acknowledges the completion of the function because message delivery to the receiver is guaranteed under the implemented protocol.   When  a  request  is  sent,  a message  timer  is started at the sender.   When the normal response for the request is received,  the timer is reset; however,  if the duration of the message operation exceeds the timeout value, a message-timeout procedure is initiated.  When the cancel command is issued, a second timer is set.  If this timer is exceeded,  subsequent cancel  commands  can be  issued.   If subsequent cancel commands are issued,  a cancel complete command must be sent and responded to.  Since the commands must be executed in the sequence in which they are received, a response to the cancel complete command ensures that there are no other cancel  operation commands  remaining in the receiver,  allowing subsequent operations to start without danger of being canceled.

Title: Document handling system having a shunt path
Inventor: ACQUAVIVA THOMAS
IPC: B65H29/60
Filed: 1993-03-31
Abstract: ABSTRACT OF THE DISCLOSURE A document handling system and method for automatically and successively transporting documents is provided. The system includes a primary path and means feeding documents in a predetermined sequence along the primary path from a stack of documents. The document handler system also provides a means for transporting selected ones of the document along the path to an upstream portion of the primary path out of the sequence and means for returning the selected ones of the documents to the other fed documents so that the combined documents are arranged in a collated manner corresponding to the predetermined sequence. The method of the present invention includes the steps of feeding documents in sequence along the path from a stack of documents, diverting selected ones of the fed documents from the defined path to an upstream portion of the path output so that the combined documents are in sequence again. The invention includes a secondary or shunt path which acts as a buffer for holding sheet units previously passing through the processing station. The secondary path is arranged to permit selected return of ones of the documents in the secondary path to the processing station while providing sequential return of the documents to the primary path for transport to the sheet output. Thus, the document handling system and method provides for selective reprocessing of documents to promote job recovery operations.

Inventor: HENDRY JAMES WATSON
IPC: B29C49/06
Filed: 1991-11-01
Abstract: A method of gas-assisted injection molding in which: 1) a first amount of plastic is injected into an article-defining cavity of a mold so that it flows therein; 2) a second amount of plastic continues to be injected into the cavity simultaneous with the injection of a charge of pressur-ized gas wherein the pressurized gas pre-vents the flow of plastic in the cavity from stopping; and 3) the charge of pressurized gas continues to be injected after the sec-ond amount of plastic is injected to distri-bute the total amount of molten plastic resin in the cavity. The ratio for the first amount of plastic to the total amount of plastic required for the preparation of the article is in the range of .2 to .7. Also, the pressurized gas has a pressure between approximately 1000 psi and 5000 psi. These steps prevent imperfections on the exterior surface of the plastic article. The gas charge is maintained under pressure within the article until the article has set up in the article-defining cavity. Finally, the gas pressure is relieved in the article and the finished article is removed from the mold. The method is particularly useful in molding articles having a relative large cross-section.
