Inventor: ILENDA CASMIR STANISLAUS
IPC: C08F255/00
Filed: 1989-03-29
Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith a good balance of tensile modulus, sag resistance and melt viscosity, is a polyolefin trunk having a, preferably relatively high weight-average molecular weight, methacrylate polymer chain grafted thereto. The graft copolymer is formed by dissolving a non-polar polyolefin in an inert hydrocarbon solvent, and, while stirring the mixture, adding methacrylate monomer together with initiator to produce a constant, low concentration of radicals, and covalently graft a polymer chain, preferably of relatively high molecular weight, to the polyolefin backbone. The graft copolymer can be separated from the solvent, by volatilizing the solvent, for example in a devolatilizing extruder, and pelletised or extruded or otherwise shaped into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a polyolefin matrix to improve its physical properties in the melt, upon cooling, and in the solid state, and is useful in cast and oriented films, solid extruded rod and profile, foamed rod, profile and sheet and blown bottles. The graft copolymer can also be used to improve compatibility between polymers in a wide range of polymer blends.

Title: Central controller with adaptive message handling characteristics
Inventor: BREEDEN ROBERT L
IPC: H04W88/18
Filed: 1990-09-04
Granted: 1995-01-17
Abstract: A central controller (40) operating as a pager terminal for receiving, handling, and transmitting messages is shown that adaptively alters its message handling characteristics in order to improve the overall throughput of the central controller. The channel loading characteristics, based upon the time of day, are used in order to vary the limitation of the size of message received by the central controller (40) as well as vary the transmission size and age of messages prior to transmission. Additionally, channel loading may be determined by determining the total size of messages within the central controller (40). In response to the total size determination, the limitation of the message size received by the controller (40) may be varied. Furthermore, the transmission size and age of messages prior to transmission may be varied in response to the total size determination. The central controller (40) may also adopt these operations in response to the combination of the total size determination and channel loading based upon the time of day characteristics.

Granted: 1997-05-13
Abstract: A system for authorizing access to a secured location, such as the vault of an automated teller machine (ATM) or the coin box of a pay telephone, without a key or combination for the secured location, and without requiring a fixed communication link extending to the location.  A service technician receives an encoded access message which identifies a present access code previously stored at the secured location, the personal identification number (PIN) of the technician, and the identification number of a portable terminal assigned to that technician.  The technician manually enters the encoded access message and the proper PIN into the terminal, where the identification number stored in the terminal and the manually-entered PIN are verified against the information encoded in the access message. If that information is authenticated, the technician then proceeds to the secured location and connects the portable terminal to a processor at that location. The encoded access message is transferred from the terminal to the secured location, where the access code previously stored at that location is compared with information contained in the encoded access message.  The technician must also re-enter the proper PIN at this time. Access is granted only if all information is verified by information in the encoded access message. If access is allowed, the access code at the secured location is replaced by a new access code contained in the encoded access message, and that new access code is stored for the next authorized access to the particular secured location.
