Title: Method and apparatus to provide a secure multicast transmission
Inventor: BHAGAVATH VIJAY K
IPC: H04L29/06
Filed: 1999-07-30
Abstract: A method and apparatus for a secure multicast transmission is provided. A  secure multicast transmission reservation, received at a multicast session security platform, is sent from a sender of a secure multicast transmission and may include, for example, information about the secure multicast transmission and information about which multicast receivers are authorized to receive the secure multicast transmission. The multicast session security platform also receives a request for security information from a requesting multicast receiver. The multicast session security platform may include, for example, a multicast session security server capable of communicating with a plurality of senders and a plurality of requesting receivers. It is determined, using information from the reservation, if the requesting receiver is authorized to receive the secure multicast transmission. If so, multicast transmission security information, such as IPSEC SA information needed to receive the secure multicast transmission, is sent to the requesting receiver.
Patent CA-2282640-A1 (CA)
Title: Process for making double metal cyanide catalysts
Inventor: HINNEY HARRY R
IPC: C08G65/12
Filed: 1998-03-02
Abstract: A process for making substantially non-crystalline double metal cyanide (DMC) catalysts having improved activity and performance is disclosed. The process comprises using a metal salt having an alkalinity within the range of about 0.2 to about 2.0 wt.% as metal oxide based on the amount of metal salt to prepare the catalyst. Surprisingly, important polyol properties such as viscosity and unsaturation improve when the alkalinity of the metal salt used to make the DMC catalysts is properly controlled. The process allows catalyst producers to enjoy the benefits of substantially non-crystalline DMC catalysts even when relatively inexpensive, technical-grade metal salts are used to make the catalyst.
