Filed: 1992-09-18
Granted: 1999-08-24
Abstract: The present invention provides for a locking mechanism for use in a door and the like. A remote handheld controller transmits coded signals to an electronic door lock. A sensor/receiver receives the signals and provides the signal to a processor which compares the coded signals against a predetermined stored signal. If the received coded signal matches the predetermined signal, then the processor generates control signals to actuate an electromechanical device, which acts solely along or about the locking axis, to enable or disable the locking latch. The user is then able to turn the door handle in a normal manner. The coded signals are comprised of two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.

Abstract: A process and a device for producing self-supporting saddle coils (96), where first, a winding receiver (10), which has a base (11) and a cutout (13), is produced to form saddle coils (46). Segments (12) can be attached to the inside contour of the cutout (13). These segments (12) are spaced with respect to each other. These spaces, also called slots (14), serve to receive wires running in the Z-direction. The constructed length of the segments (12) is such, that their ends extend beyond the base (11), thus forming the chambers (16.u, 16.o) between the edges (15.o, 15.u) and the ends of segments (12) that curve away from the centerline. This winding receiver (10) is wrapped by a winding device (21), which wraps the wire in the slots (14) and the chambers (16.u, 16.o). When the winding pass of saddle coil (46) is formed, the wrapping wire (32), covered with thermoplastic material, is heated so that the windings of the wrapping wire (32) are bonded to each other, after cooling. The segments (12) are then removed from the cutout (13) and the finish-baked saddle coil (46) can be pulled out of the cutout (13).

Abstract: A process for removing sulphide(s) from sour gas comprising contacting sour gas with a treatment agent comprised of make-up triazine. The treatment agent extracts sulphide(s) from the sour gas to sweeten the gas and form a residual solution comprised of a sulphinated component and an alkanolamine component. The sulphinated component of the solution is substantially separated from the alkanolamine component of the solution by decanting.      Dithiazine and trithiane is crystallized out of the spent sulphinated component and removed from the process.      Aldehyde is added to the remaining alkanolamine component to form a sulphide reactive agent. The sulphide reactive agent is combined with make-up triazine to produce the treatment agent for contacting with the sour gas. The present invention also includes a system for completing the above steps comprising feed means for supplying the treatment agent, H2S reactor for contacting the sour gas with the treatment agent, a decanting vessel for separating the sulphinated component from the alkanolamine component, a crystallization unit for crystallization of the dithiazine and trithiane, an aldehyde reactor for adding the aldehyde to the alkanolamine component to form the sulphide reactive agent and a feed line to add the sulphide reactive agent to the treatment agent.

Granted: 1997-09-23
Abstract: A Medium Access  (MAC) Protocol is utilized for wireless radio access for a plurality of remote stations to a base station on a LAN.  The MAC protocol is based on a reservation scheme for user data  traffic  and  a  random  access  technique  for  control  and signalling traffic. There is a time division fixed frame structure in which time is slotted, and time slots are grouped into fixed frames consisting of data and control subframes or periods.  The fixed frame structure consists of three periods (A, B, and C) along with their respective headers.  The first period, the A period, is the outbound channel which is used exclusively for data transfer from the base station to the remote stations.   The following period,  the B period,  is the inbound channel that is used for contention-free data transfer from the remote stations to the base station. The allocation of the data slots in the A and B periods is performed by the base station.  The last period of the frame, designated as the C period, is the control channel used for the transmission of reservation requests and data from the remote stations to the base station in a random-access contention mode using a slotted Aloha protocol.  The duration of the three periods may be varied using a movable boundary technique.  The base station estimates the number of actively transmitting remote stations utilizing feedback information from the remote stations.  This estimate is broadcast to the remote stations as control indicia to control their transmission attempts in the C period, thus yielding high transmission efficiency.

Title: Automatically relaxable query for information retrieval
Inventor: LIZEE ROBERT
IPC: G06F16/9032
Filed: 1994-03-31
Granted: 1998-08-25
Abstract: A data processing system is disclosed for automatically querying databases. The system uses an Automatically Relaxable Query (ARQ)  consisting of a list of query conditions ordered in descending degree of importance. When an ARQ is processed, the database is queried on the first condition of the ARQ; if any object is found, the first condition is labelled. Then, the system proceeds with a query composed of all the conditions labelled previously in conjunction with the next condition of the ARQ; if any object is found then this next condition is labelled. The last step is repeated until all the remaining conditions of the ARQ have been used. The system then reports which conditions were labelled. If the query composed of the labelled conditions matches only few objects of the database, the  objects may be  automatically retrieved.  The automatic querying  with  an  ARQ  enables  faster  searches,  minimizes interaction between the database and the user and permits off-line preparation of database querying.
