Title: Encryption key exchange protocol
Inventor: PARISIEN BRIAN R
IPC: H04L9/08
Filed: 2000-10-23
Abstract: The calculation of encryption keys is a processor intensive undertaking that is not suited for "thin client" terminal devices typically used for session applications in an Internet Protocol network. The present invention provides an encryption scheme for use with such terminal devices for the secure transmission of session data that minimizes session set-up delays associated with the exchange of encryption keys.      First, keys are negotiated between network elements using prior art techniques (e. g. shared secret, IKE, Diffie-Hellman, RSA).      Then, security is maintained by refreshing symmetric keys after each session under cover of an existing key. Perfect Forward Security (PFS) can be provided by "breaking the chain" through periodic key refreshes during system idle times.

Inventor: STAUNTON JAMES
IPC: A61P31/04
Filed: 1999-06-29
Abstract: A polyketide synthase ("PKS") of Type I is a complex multienzyme includ-ing a loading domain linked to a multi-plicity of extension domains. The first extension module receives an acyl starter unit from the loading domain and each ex-tension module adds a further ketide unit which may undergo processing (e.g.  reduc-tion). We have found that the Ksq domain possessed by some PKS's has decarboxy-lating activity, e.g. generating (substituted) acyl from (substituted) malonyl. The CLF  domain of type II PKS's has similar activ-ity. By inserting loading modules includ-ing such domains into PKS's not normally possessing them it is possible to control the starter units used.

Title: Springless seat cup
Inventor: LABINSKI JEFFERY J
IPC: F16K31/52
Filed: 2001-02-13
Abstract: A seat cup seal for a valve includes a base portion and a nipple portion projecting outwardly from the base portion. The nipple portion and said base portion define a blind bore about a longitudinal axis that opens in the base portion.  The nipple portion defines a transverse end wall at an outermost end relative to the base that is adapted for sealingly engaging an associated valve seat. A flexible shoulder portion interconnects the base portion and the nipple portion so that said nipple portion is selectively movable between a first, relaxed position where the transverse end wall is spaced a first distance from the base and a second, retracted position where the transverse end wall is spaced a second distance from the base, with the second distance being less than the first distance. A plurality of biasing ribs projects outwardly from and extending between the base portion and the nipple portion.  The biasing ribs, which are conformed in one of several suitable arrangements, bias or urge the nipple portion toward the first position when it is in its second position. In this manner, the seat cup does not require a coil spring or other separate biasing agent to urge the transverse end wall into sealing engagement with the associated valve seat.

Filed: 1999-05-12
Abstract: The present invention relates to a method for end-to-end joining of paper ro ll cores into a continuous core master. The primary goal of the invention is to  produce usable cores from those returned for recycling after use. In the method, the ends of core sections are reworked into complementary shapes required for a mating joint, glue is applied to the complementary mating surfaces of the joint and the core section ends pushed in the axial directio n abutting each other and the glue is set. According to the invention, the cro ss section of the cores is trued circular at least over the area of the joined core sections by applying a radially expansive trueing force on the joint. T he radial trueing force is also advantageously employed for braking the axial travel of the core sections during the joining operation. The invention also  concerns an apparatus suited for implementing the method.
