Title: Arrangement for forming a conference call
Inventor: ESCHMANN J
IPC: H04M3/56
Filed: 1982-12-09
Abstract: A conference circuit in a digital telephone switching system includes a first code converter (CCL), which converts nonlinearly coded speech samples into linearly coded speech samples, and adder (ADD), which sums the converted speech samples originating from the participants in the conference, and a second code converter (LCC), which reconverts the sum values into nonlinearly coded speech samples. To avoid distortion without increasing the insertion loss, the speech samples of the individual participants are integrated with respect to time and compared in an evaluation circuit (EVC). The speech samples of the loudest participant are fed to the adder unattenuated, while those of all other participants are attenuated by a predetermined value before being added.

Title: Road testing apparatus
Inventor: SCRIVENER STEPHEN PEDDER
IPC: G01N33/42
Filed: 1983-05-02
Abstract: A road testing apparatus has a framework extending over a test portion of road pavement and has tracks with upwardly curved ends along which wheels of a trolley unit roll so that the trolley unit decelerates as it approaches an end position to cause kinetic energy to be transformed into potential energy and when return motion trolley commences the potential energy transforms back to kinetic energy. The trolley unit has a pivotally mounted base structure carrying a test load and a pair of road wheels which are mounted so as to be steered by the trolley as it progresses in a forward direction along the test pavement, additional wheels of the trolley running up an end portion of the track to lift the road wheels off the road surface as the end position is reached. A telescopic linkage latches into engagement at this end position to retain the road wheels in an elevated position relative to the trolley so that, during return motion, the road wheels can continue to rotate in the same direction but engage on the bottom of a base plate structure of the framework to drive the trolley in the reverse direction, the latch arrangement being released when the trolley reaches the opposite end position to permit a further cycle of operations.

Title: Combinations of tumor necrosis factors and anti-inflammatory agents and methods for treating malignant and non-malignant disseases
Inventor: FIERS WALTER C
IPC: A61K38/00
Filed: 1987-10-15
Abstract: Combinations and methods for the treatment of malignant and non-malignant diseases. More particularly, this invention relates to combinations of natural or recombinant tumor necrosis factors (''TNF'') and non-steroidal anti-inflammatory agents, such as indomethacin and ibuprofen, useful for the growth inhibition or killing of transformed cells. According to this invention, the non-steroidal anti-inflammatory agents are used to reduce or eliminate the toxic side effects of high doses of TNFs employed in the treatment of malignant and non-malignant neoplastic diseases. Advantageously, the combinations and methods of this invention allow the administration of higher doses of TNF than those tolerated in conventional treatment regimens based upon TNF alone.
