Abstract: For delivering parts successively received in  shipment units  by  parts  deliverer  to  part  use  positions,   the delivering operation time required for each parts  deliverer is  uniformalized.  A uniformalizing plan is  produced,  and the delivering operation is continued according to the plan.    The  delivering  operation  time  is  calculated  for   each shipment  unit (first step).  The  assignment  of  shipment units to parts deliverers is shifted such as to uniformalize the  delivering  operation  time for  each  parts  deliverer (third  step).   The shifting operation is  continued  until uniformalizing  is  obtained.  As  a  result,  uniformalized assignment can be realized.

Title: Method of shaping a cell stream including both user cells and operation and maintenance cells
Inventor: PETIT GUIDO H M
IPC: H04L12/56
Filed: 1995-02-21
Abstract: A shaping method is proposed in which cells (U1-U7, 01-06) of a cell stream (CS1) are mutually delayed to obtain a shaped cell stream (CS2). For this a shaping delay is used which depends upon the type of the cells which are so delayed in order for consecutive user cells (U1-U2, U2-U3, ...) to be mutually delayed over the inverse (TU) of the peak cell rate negotiated for these user cells (U1-U7).          The above is obtained by making this shaping delay equal to the above inverse when adjacent cells are user cells (U1-U2), to a fraction (TU/3) of this inverse when the second one of these adjacent cells is an operation and maintenance or OAM cell (01-07) and to the difference between the above inverse and the number of consecutive OAM cells inbetween two user cells (U5-U6) times the above fraction if the first one of said adjacent cells is an OAM cell (03) whilst the second one is a user cell (U6).

Inventor: TAKEDA MASAAKI
IPC: G01M3/26
Filed: 1993-08-31
Abstract: In a method for detecting leakage in a pipetting apparatus, the inner pressure of the pump connected to the nozzle tip is measured to discriminate the presence of leakage objectively.        In step 202, distilled water 90 is aspirated.      When the inner pressure P1 of the pump after aspiration is roughly equal to the atmospheric pressure, a leakage is determined. Further, in step 203, after the inner pressure P1 of the pump has been measured after aspiration in step 202, the tip 36 is kept stopped for 30 sec, for instance without raising the tip, and the inner pressure P2 of the pump is measured again by the pressure sensor. When this inner pressure P2 is different from the inner pressure P1 previously measured, a determination that there is a leakage is made. Further, in step 204, aspirated distilled water 90 is dispensed into the same test tube 62. The inner pressure of the pump is kept monitored by the pressure sensor. In this case, when the pressure changes abruptly, a determination that there is a leakage is made.     The leakage detection is completed at the time whenever the leakage is detected.

Inventor: RABIPOUR RAFI
IPC: H04B3/06
Filed: 1995-05-17
Abstract: In methods and apparatus for estimating the frequency response of telecommunications channels, signals carried on the channels are divided into pluralities of signal segments of limited duration, unvoiced signal segments are identified, and spectral components of the unvoiced signal segments are measured.  The measured spectral components may be integrated over time to derive time-averaged measurements of the spectral components.  The time-averaged measurements may be compared to corresponding components of expected unvoiced signal spectra to improve the accuracy of the frequency response estimates.  Filters may be inserted in the channels to adjust the frequency responses, the filters having filter characteristics selected in response to the measured spectral components. The methods and apparatus can be used to compensate for poor bass frequency response in voice channels.

Title: Tap head for beverage containers or vessels
Inventor: DEGENKOLBE HORST
IPC: B67D1/08
Filed: 1994-05-06
Abstract: Tap  heads  for beverage  containers  or  barrels  respectively comprise a plunger able to be actuated by a hand lever,  a beverage connection, a connection for a gaseous pressure medium and a container connection.  In previous tap heads, the problem exists that a high gas pressure is maintained in the interior of the tap head, when the tap head is closed.   Due to this the housing gasket of the tap head is pressed against the flange of the fitting, so that the tap head can only be released from the flange with a considerable application of force.            In order to provide a tap head,  which makes it possible to respectively remove the gas pressure without risk in the interior of the tap head, it is proposed that a relief valve is connected to the interior of the tap head.

Time stamp information obtained from the PES header is appended to the picture information for storage in a video memory. Picture information can subsequently be read from the memory and decoded using the appended time stamp information without having to reaccess the PES header. Various schemes for detecting, masking and recovering from transmission errors are disclosed.

Filed: 1994-12-06
Abstract: The invention pertains to a process and device for regulating the position of the tip of an electrode immersing in an electric furnace heated by electric arc or resistance heating. To measure with precision the position of the electrode tip and to position it in operation, the invention proposes that a series of gas containers (26) be introduced into the electrode in succession at certain intervals, with each gas container given a serial number (ni). The position of the electrode tip is determined by computer from the data of the last gas container with the serial number (nj) and the current number of the melted-open gas container, determined by gas analysis, using the gas that rises in the furnace vessel through the melting process. Control technology is then applied to the drive (41) of the electrode bearing device (20).
