Title: Evaluation and treatment of patients with progressive immunosuppression
Inventor: OCHOA AUGUSTO C
IPC: A61P31/04
Filed: 1993-04-06
Granted: 2003-09-30
Abstract: A soluble immunosuppressive factor present in serum derived from tumor-bearing mammals, is associated with changes in TCR protein subunit levels, T lymphocyte signal transduction pathway proteins.  These changes provide a method of determining the level of immunosuppression in a mammal by determining the level of expression of at least one selected TCR subunit protein, a protein in the T lymphocyte signal transduction pathway, or of the NF-KB/rel family and comparing the level and pattern to chat found in non-immunosuppressed individuals: The method is useful to identify patients having T lymphocytes capable of acti-vation for immunotherapy and for identifying agents which cause or reverse immunosuppression. An isolated immunosuppres-sive factor associated with the level of expression of the proteins is useful for suppressing the immune response, for example, in organ transplantation.

Title: System for detecting and classifying movement of objects along a passage
Inventor: ZAAIMAN BEN THOMAS
IPC: G07C9/00
Filed: 1993-10-07
Granted: 1999-09-07
Abstract: For detecting and analyzing movement of objects along a passage, a plurality of sensors spaced along a length of the passage are utilized to gather data relating to a historic two-dimensional representation of the presence or absence of objects on spaced lines extending transversely to a longitudinal axis of the passage. One dimension is time and the other dimension is the sensor index. A computer is utilized to classify segments of the historic representation by means of computerized pattern recognition technique, such as an artificial neural network. In one application, the results of the analyzing step may be utilized as inputs to an object counter for counting the number of objects moving in a selected direction along the passage in a defined period of time.

Abstract: A multi-stage froth flotation process is provided for concentrating sulphide minerals or middlings containing non-ferrous metal values such as nickel, cobalt and copper, which co-exist with significant amounts of pyrrhotite. The process is carried out without relying on any specific reagent as pyrrhotite depressant, but rather by exploiting the natural pulp environment with low REDOX potentials generated by mild steel grinding media in the grinding step preceding the froth flotation. The concentrate from the flotation stage(s) in which the REDOX potential rises above a predetermined value, is recycled back to the grinding step and/or to preceding flotation stage(s) from which concentrate is collected as the final product or is subjected to an up-grading in a further cleaning stage.

Abstract: In a vector quantizer device including an input vector quantizer (11) for a current input vector of an input vector sequence to produce a first quantized vector and a predicted vector quantizer (13) responsive to the input vector sequence for quantizing into a second predicted vector a predicted vector predictive of the current input vector with quantization, a predicting unit (37) produces the predicted vector in response to a predetermined number of output vectors including such first and second quantized vectors.  Responsive to a prediction error vector between the current input and the predicted vectors, a control circuat (35) controls, at a time, input and output switches (31, 33) to supply the input vector sequence to only one selected quantizer of the input and the predicted vector quantizers and to produce as one of the output vectors one of the first and the second quantized vectors that is produced by the selected quantizer.  The first and the second quantized vectors are produced as two of the output vectors when the prediction error vector is greater and smaller than a threshold value, respectively.

Title: Piston advance mechanism for automatic taper
Inventor: MCMILLAN DONALD MARK
IPC: E04F21/00
Filed: 1996-01-22
Granted: 1999-02-23
Abstract: The mechanism consists of a crankshaft and connecting rods driving two rods which extend through the full length of the cylinder of the taper.  The rods reciprocate 180° out of phase with each other and pass through a piston assembly.  Clutch mechanisms in the piston assembly engage when the rods are moving toward the head assembly and do not  engage  for the  opposite motion.  As  a result  the piston  assembly  advances  toward  the  head  assembly  an increment of motion each time one of the rods moves in that  direction.   A  mechanism  in  the  piston  assembly engages  the  head  end  of  the  cylinder  as  the  piston assembly approaches the head end and prevents the clutches from engaging so that the piston assembly does not jam against the head end of the cylinder.  Also, mechanism is provided  to  disengage  both  clutches  and  keep  them disengaged so that the piston assembly is free to move as the cylinder  is being filled.   This mechanism involves rotating the rods to drive cams which engage the clutches to hold them disengaged.  An alternate driving mechanism between the crankshaft and the oscillating rods enables adjustment of the amount of motion of the rods for turn of the crankshaft.

Abstract: A timing technique for a Quantization-Level-Sampling (QLS) modem puts timing information in a downstream pulsed signal transmitted from the public switched telephone network (PSTN) to the QLS modem. In response to this timing information, the QLS modem synchronizes to the network sampling clock of the PSTN. In particular, the pulsed signal includes data-bearing samples, which were provided by a far-end QLS modem, and at least one non-user-data-bearing (NUDB) sample in which the level of this NUDB sample periodically alternates. The QLS modem extracts timing information from this periodic alternating signal level to synchronize the QLS modem to the network sampling clock.
