Title: System for communicating with an adsi-compatible telephone via a service circuit node
Inventor: MORGAN LARA FELKER
IPC: H04M3/533
Filed: 1994-04-13
Granted: 1999-04-20
Abstract: A telephone display system (10) for communicating data via a service circuit node (11) connected to a PSTN (13) for presentation by a visual display (26) connected to an Analog Display Service Interface (ADSI)-compatible telephone (14). In response to a service selection signal carried by an incoming telephoneline (21), the service circuit node (11) generates information signals containing textual information and telephone instructions. The service circuit node (11) also connects the incoming telephone line (21) to an adjunct processor (12) and sendsthe information signals to the adjunct processor (12).  In response, the adjunctprocessor (12) modulates a carrier in accordance with the digital information signals and transmits the resulting analog information data over the telephone line (21). If the telephone instructions include an initial instruction for causing the ADSI-compatible telephone to enter a data mode, the adjunct processor also converts the digital initial instruction into an analog format for transmission over the telephone line. The visual display (26) enters the data mode and displays the textual information.

Abstract: A multiplexed synchronous / asynchronous data bus (109) uses three communications lines (T, C, R) to convey bi-directional synchronous data between two data devices (115, 609) at a relatively low data transfer rate. The data bus is configured as a full-duplex asynchronous data bus by communicating a false address between the two data devices on two communications lines (T, C) using the synchronous data bus, holding the two communications lines (T, C) in a logic high state for a period of time, and continuing to hold one of the two communications lines (C) in the logic high state during full-duplex asynchronous communication. Full-duplex asynchronous data can then communicated between the two data devices (115, 609) at a higher data transfer rate on two of the three communications lines (T, R).

Title: Filtration
Inventor: WINGE STEFAN
IPC: C07K14/755
Filed: 1995-06-22
Granted: 2005-07-05
Abstract: The present invention relates to a method of virus-filtering a solution that contains at least one macromolecule, by virtue of the total salt content of the solution lying in the range of from about 0.2 M up to saturation of the solution with the salt concerned. The inventive method reduces the residence time and the extent to which the solution need to be diluted, and optimizes the yield when virus-filtering primarily proteins, polysaccharides and polypeptides. The reduction in virus content is at least as good as with conventional techniques where the total salt content is low. The present invention facilitates virus filtration with the aid of the so-called "dead-end" technique, which affords several process and economic advantages in comparison with the tangential virus-filtering technique normally used. When virus-filtering the plasma protein factor IX, the yield obtained in the virus-filtering stags is increased from about 70% to above 95%, by raising the salt. content of the solution in accordance with the present invention.

Title: Determining sinr in a communications system
Inventor: ABU-DAYYA ADNAN
IPC: H04L1/06
Filed: 1998-02-04
Granted: 2002-12-31
Abstract: Diversity path signals, each comprising time division multiplexed symbols in a time slot including known symbols constituting a reference signal, are combined with respective weights to reduce co-channel interference. The weights are determined, from a correlation matrix and a reference signal correlation vector, using a sliding window starting with synchronization symbols and/or CDVCC (coded digital verification colour code) symbols as the known symbols. SINR (signal to interference plus noise ratio) is determined for each window position from elements of the correlation matrix and the reference signal correlation vector. The determined SINRs are averaged through the time slot, over a plurality of time slots, and for the diversity paths to provide an accurate determination of SINR within a short period. The SINR provides a reliable signal quality parameter that is useful in a cellular communications system for procedures such as hand-off, adaptive channel allocation, dynamic power control, and cell tiering.

Title: Cache device
Inventor: UESUGI TAKAHIKO
IPC: G06F12/08
Filed: 1998-06-15
Granted: 2002-08-13
Abstract: A cache device of the present invention has a path through which the desired data contained in block load data transferred  from  a  main  memory  are  delivered  to  a processing unit which required the desired data, even when cache access by an instruction for accessing the main memory results in a cache miss.    This path is different from a path through which the desired data is read from a data array of the cache device when a cache hit occures.          Namely, the path in question neither contains a path from the main memory to the data array nor a path from the data array to a general purpose register which the processing unit can refer to, and allows the desired data delivered from the main memory to be directly transmitted to the processing unit.  The cache device, as soon as it finds the desired data out of block load data delivered from the main memory, writes them into the general purpose register by way of the path in question.  The block load data delivered from the main memory are stored in a data buffer, and then written sequentially into the data array.

Abstract: A jaw assembly is provided for a power tong or back-up tong to make up and break out a pipe section. The jaw assembly includes a jaw element for transferring torque from the tong to the pipe section, and a means for moving the jaw element into and out of gripping engagement with the pipe section. At least one die holder is rotatably mounted to the jaw element and is adapted to freely twist about a first axis oriented generally parallel to a longitudinal axis of the pipe section when engaged with said jaw element. The rotation of the die holder about the first axis allows the die holder to align itself with the pipe section upon engagement therewith and to provide an independent camming action against the pipe section to at least radially maintain the die holder's grip on the pipe section and avoid slippage therebetween when transferring torque. The jaw assembly may therefore be used on a range of pipe sizes without having to change the jaw

Abstract: Connectors used in manufacturing composite wall structures to substantially prevent forms from being displaced in response to pressure generated by concrete poured between the forms. In a completed composite wall structure, the connectors extend through two structural layers and an insulating layer positioned therebetween. The composite wall structures are formed by positioning the insulating layer between and in a spaced-apart relationship to the two forms. The connectors are subsequently inserted through the insulating layer and the forms. As concrete is then poured into spaces between the forms and the insulating layer, a bearing surface on a form retention segment, which extends beyond the outer surface of the forms, abuts the forms and prevents them from moving away from the insulating layer. The bearing surface is either directly positioned on the form retention segment or on a form locking device attached to the form retention segment.  After the concrete hardens, the forms are removed and the form retention segments are optionally detached from the remainder of the connector. The surface of the connectors optionally includes an adhesion promotion material or mechanical anchoring structure to improve the bond between the connectors and the structural layers.
