Title: Methods for detection of rearranged dna
Inventor: PILARSKI LINDA M
IPC: C12Q1/6886
Filed: 1997-06-03
Abstract: The invention provides methods for the identification of members of a malignant lymphocyte clone by analysis of clonotypic DNA  rearrangements of T cell or B cell receptor genes. The DNA or RNA from isolated single tumor cells is amplified by PCR using consensus primers to the VDJ region of the receptor genes, and the sequence of the VDJ  region is obtained from each. The clonotypic sequence of the malignant clone is identified as the most frequent VDJ sequence amplified.  Individual-specific PCR primers for the VDJ region are then designed based upon the clonotypic sequence. These specific PCR primers are used to detect and quantitate clonotypic cells in subsequent patient samples using in situ PCR or in situ RT-PCR. Fractionated or unfractionated samples of blood or bone marrow, as well as tissue sections can be analyzed. The methods provide a highly sensitive and quantitative means to monitor the progress of disease and the efficacy of treatment protocols, as well as to detect members of the malignant clone in autologous bone marrow cells destined for transplant.

Title: Current limiting circuit
Inventor: MORAN RICHARD JEROME
IPC: H01H47/10
Filed: 1997-09-10
Abstract: An electronic circuit (125), and corresponding method, for controlling the closing velocity of electrical switchgear (120), includes an actuator (120) and a current detection circuit (125) that detects whether an optimum amount of current is flowing through the actuator. When the optimum amount of current is detected, a current optimizing resistor (135) is inserted into the path of the current flowing through actuator, thus limiting the current flowing through the actuator to the optimum amount. This, in turn, limits the closing velocity of the electrical switchgear and minimizes contact bounce.

Inventor: SCHMITZER HEIDRUN
IPC: H04B10/2507
Filed: 1999-07-23
Abstract: Optical communications networks include optical fibres (30) that subject the polarization of the light passing through the fibre and the polarization-dependent components (50) to vary over time. In order to optimize the optical information processing in the individual components of the optical network, it is essential to keep the polarization of the light, as well as its frequency and intensity, within narrowly defined limits. This is achieved in that light that is of the characteristic polarization of the polarization dependent components is sent to every component (50) of this sort. Even though numerous attempts have been made to do so, up to now it has not be possible to develop a simple polarization regulating device that can be manufactured in a cost-effective manner.     According to the present invention, the polarization regulating device (10) comprises an input (20) to receive light with a polarization P e, and output (40) to decouple light with a predetermined polarization P a, an electrically controllable polarization adjustment device (60) to convert the light that is received that is of polarization P e into light with the predetermined polarization P a, a light-sensitive detector (90) that follows the analyzer (80), and a device (100) that supplies the control signals, this being connected electrically on the input side with the light-system detector (90) and on the output side with the polarization adjustment device (60).

Title: Combined cycle power plant
Inventor: YAMAMOTO HIROYUKI
IPC: F02C7/18
Filed: 1998-01-23
Abstract: A combined cycle power plant mixes steam heated to a high temperature by cooling a high temperature cooled part of a gas turbine. Other steam favorably guarantees the safety of the alternating current apparatus, so that it is operated stably over a long period of time. The combined cycle power plant has a mixing tube that mixes exit steam from a steam cooling system and a bypass steam. The exit steam from the steam cooling system that has been heated by cooling the high temperature cooled part of this gas turbine and the bypass steam that bypasses this high temperature cooled part in order to control flow volume and temperature of the steam introduced into the high temperature cooled part are introduced into the mixing tube and mixed. Thus a mixed superheated steam having uniform pressure and temperature is formed, with no deleterious effect on any downstream equipment.

IPC: A61B19/00
Filed: 1998-05-15
Abstract: A surgical method and apparatus for accurately aligning the trajectory of, guiding of, and introducing or withdrawal of an instrument is disclosed. The apparatus includes a base which has a movable member movably attached to the base. The movable member has a passage therein which forms a portion of the trajectory path. A positioning stem further includes a first locator and a second locator. The first and second locators are associated with two different portions of the positioning stem so that they are essentially two points on a line. The first and second locators are also locatable by a scanning or imaging system. The positioning stem is removably attached to said movable member and used to position the movable member. Moving the movable member also moves the passage therein to different trajectories. Once the passage within the movable member more or less is aligned with a target within the body, a locking member locks the movable member into a fixed position. The movable member can be moved to different trajectories using a first hydraulic system. A second hydraulic system can be used to introduce or withdraw an instrument to or from the patient. A mechanical advancement tool can be substituted for the second hydraulic system. The surgical instrument may also be provided with a remote portion for controlling the instrument from a remote location. The instrument can also be computer controlled.
