Abstract: DART WITH FLIGHT LOCK          Abstract of the Invention A dart comprises a shaft having a flight lock for securely mounting a flight on the shaft.  The flight lock comprises a threaded post extending rearwardly  from the shaft body and a flight holder mounted on the post.   The flight holder has a threaded axial bore at its front end for receiving the post and an X-shaped slot at its rearward end which extends forwardly to a position overlapping the bore.   A flight is inserted into the slit and is pushed forwardly until it enters the back of the bore.  The flight holder  is  then  threaded  onto  the  post  until  the  post engages the flight and wedges it between the post and the wall of the flight holder defining the bore.   In another embodiment of the invention, the flight lock comprises an x-shaped slit extending forwardly from the rearward end of the shaft.  A locking hole extends transversely through the shaft at a position rearward of the forward end of the slit.  A locking pin is inserted into the locking hole and through a flight lying within the slit to lock the flight in the shaft.

Granted: 1994-12-20
Abstract: A method is provided for obtaining images for use in dis-playing a three-dimensional illusion which includes the step of obtaining first and second images of a subject volume having foreground and background portions with the points of origin of those images located in a first plane which includes left and right points of origin of an observer of the subject volume and which is normal to the optical axis of that observer.  The first and second points of origin are also respectively located equi-distant above and below a first line interconnecting the left and right points of origin and are located along a second line which is normal to and bisects the first line.  The first and second optical axes are aligned to converge in a second plane parallel to the first plane which includes the foreground portion of the subject volume within the field of view of the observer which is closest to the first plane.  A support apparatus is provided for using one or two imaging devices in implementing the method of the subject invention and an alternative support apparatus is disclosed which incorporates a teeter-totter arrangement to auto-matically provide for maintenance of convergence of the optical axes in the second plane upon adjustment of the effective first and second points of origin above and below the first line con-necting the left and rights points of origin of the observer.          Image recording medium containing images produced by the above method is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE        A method for renewing an existing pipeline comprises the steps of advancing a shield tunnelling machine from one end of an existing pipe defining the existing pipeline to the other end thereof, excavating at least the existing pipe by the machine and disposing a new pipe in an excavated spot while the machine is advanced, whereby the existing pipeline is renewed by breaking the existing pipe embedded in the ground while laying the new pipe therein.  An existing pipeline renewing apparatus embodying the method described above comprises a shield tunnelling machine for excavating an existing pipe embedded in the ground so as to defining an existing pipeline and a means for disposing a new pipe in a spot excavated by the machine.  Accordingly, since the new pipe is disposed while excavating the existing pipe by the shield tunnelling machine, it is not necessary to excavate the spot, in which the existing pipe to be renewed is laid, by a driving method.

Abstract: ABSTRACT OF THE DISCLOSURE         The cooling-air ducting of the axial flow gas turbine runs in the area of the last blading stage (9 + 14) radially inwards of the heat accumulation segments (23, 24) inside the outer boundary of the rotor (4) and through blade root channels (21) in the blade roots of the last moving blade ring (9) and finally through a cooling-air blade ring (28) fixed to the rotor into the diffuser into which the cooling-air flow enters with a velocity vector which essentially corresponds to the average velocity vector of the exhaust-gas flow entering into the diffuser.  This avoids the flow losses which occur when the cooling-air flow passes out into the exhaust-gas flow in the area of the last stage or stages.  At the same time, the temperature difference between the rotor circumference and the last rotor disk (4), likewise cooled by tapped air from the compressor, is in this way reduced, as a result of which the thermal stresses in the rotor are also reduced.

Inventor: LIDINSKY WILLIAM P
IPC: H04L12/56
Filed: 1988-11-29
Granted: 1993-03-23
Abstract: IDENTIFICATION AND AUTHENTICATION OF END USER SYSTEMS FOR PACKET COMMUNICATIONS NETWORK SERVICES Abstract A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user.

Abstract: ABSTRACT      TECHNIQUE FOR IMPLEMENTING BYTE-WIDE UART     A technique for transferring byte-wide serial data from a UART to a word-wide parallel data bus and vice versa is provided.  Input control signals are established for the UART to specify the type of transfer to be implemented:  odd byte, even byte or word.  When a single byte is being sent from a CPU to a UART FIFO for serial transmission, then the predetermined storage location within the UART depends upon the address and the number of bytes being sent, not upon the byte's position on the data bus as is conventional.  Similarly, when a serially received byte is to be transferred from a UART FIFO to the CPU, the next byte available is transferred to the data bus regardless of the position on the bus that it will occupy; in other words, regardless of whether it will be in the high byte or low byte position.
