Title: Element for sealing and monitoring a body, in particular a refuse dump
Inventor: RUTHROF KLAUS
IPC: B09B1/00
Filed: 1992-03-19
Abstract: The invention relates to an element for sealing and monitoring a body  (1).  Provision is made for two seals  (4, 5) to be spaced apart by supporting elements (6), while at least one channel (7) remains free between the supporting elements 16). At the outlet openings of said channel one or more sensors (18) is or are disposed. The seals  (4,  5) are connected to each other at their edges. The supporting elements (6) consist of a material which is permeable but resistant to flow, preferably a material  whose  flow  resistance  perpendicular  to  the channel  (7)  is less than that parallel to the channel (7). The position of a leak (29) can be determined with the aid of two sensors (18), which in a refuse dump also determine whether the leak (29) is located in the lower or upper seal (4, 5).

Abstract: A threaded pipe connection as shown in Figures 1, 4, 5, 6 or 7, having a thread form such as depicted in Figures 8-11, that has: improved sealing; increased resistance to mechanical loads; easy assembly and low makeup torque. Both pin (31) and box (45) may be cut on non-upset pipe ends and result in nearly 100 percent joint efficiency. Tension flank (33) and compression flank (34) may be formed on pin (31) at high flank angles measured from the tubular axis so as to withstand high axial loads without forcing the pin inwardly and the box outwardly, which would tend to separate the mating threads, break the seal and jump threads. Low torque is assured by the complementary forms of pin threads (32) and box threads (42) which confine the thread dope (49) to remain in the root gaps (52) and (54) during assembly.

Abstract: The present invention provides an apparatus and method for performing polarization-insensitive four-photon mixing of optical signals.  The polarization-insensitive optical mixer receives an input optical signal and two substantially orthogonally polarized pump signals.  The input optical signal and the two substantially orthogonally polarized pump signals are combined in a beam combiner and then four-photon mixed in a first nonlinear mixing device to produce a number of mixing products. The two substantially orthogonally polarized pump signals may he generated in an orthogonal pump signal generator which includes a second nonlinear mixing device for four-photon mixing the first pump signal and a mixing signal to produce a second pump signal which is a phase conjugate of the first pump signal.  Certain of the mixing products represent phase conjugates of the input optical signal, and are therefore useful in compensating for chromatic distortion in optical fiber.

IPC: H04Q11/04
Filed: 1994-10-21
Abstract: Method for automatically adapting and configuring the speed of a terminal adapter to the rate 56Kbps or 64Kbps which is used by a calling adapter. After the sending in the called terminal adapter of the CONNECT message which is sent to the ISDN NETWORK in accordance with CCITT Q.931 Recommendations,  the called TA is initialized to a rate of 64 Kbps and then continuously transmits an alignment pattern ALL_ONES while starting a first timing process (T1). This first timing process will cause the called TA to switch to a 56Kbps speed if the 64 Kbps validation process does not succeed.  The  method  then  involves  the  step  of  checking  the reception of a ALL_ZEROS pattern coming from said calling adapter (20) before the end of said first predetermined period (T1). If this case, a 64 Kbps validation process will be performed which comprises the checking whether a ALL_ONES pattern is received within a second period  (T2),  in which case the 64 Kbps rate configuration will be validated. On the contrary, if the ALL_ZEROS pattern is not received at the end of the first period (T1), a 56 Kbps rate validation process is initiated which is based on the detection of a so-called 56 Kbps pattern within the data flow. The 56 Kbps pattern is defined as being a number of n bytes with the first bit of every byte being set to a one. Additionally, the 64Kbps validation process involves the checking of the continuous receiving of said ALL_ZEROS pattern during said first period (T1) as long as the ALL_ONES pattern is not yet received, and at the end of said first period (T1) validating the 64Kbps rate.
