Abstract: A round bar blade (10) and a cutter head (8) provided especially for the same are described. The blade has a shank with a generally round cross-section for being fixed by clamping means (28, 30) in a blade bore (12) of the cutter head (8). A substantially planar positioning surface (38) serving as an engagement surface for the clamping means (28, 30) is formed along the shank length in the extension of a cutting face (43) formed on the cutting end (40)  of the round bar blade  (10)  parallel to the longitudinal blade axis. The cutting face (43) and the positioning surface (38) lie in one and the same plane parallel to the longitudinal blade axis. They are not reground during use and can therefore have a coating which increases the serviceable life of the blade. The clamping means are wedging devices which press with their clamping surface against the positioning surface (38) of the round bar blade  (10)  in the same direction in which the load during operation also acts. The round bar blade (10) and the cutter head (8) can be produced at low cost, the round bar blade has a long serviceable life, can be easily set up in the cutter head (8) and also maintains its set-up during operation under load.

Inventor: GALASSI ROSSANO
IPC: G01R31/34
Filed: 1997-07-29
Abstract: A probe positioning assembly for an armature tester has a plurality of electrical probes corresponding to the number of commutator bars in the armature to be tested.  The probes are mounted on insulating blocks that are connected by spring arms to an insulating ring.  In their neutral positions, the probes define a circular opening into which the armature can enter with clearance between the probes and the commutator.  An actuator in contact with each support block also contacts at its other end a flexible membrane defining one wall of a hollow annular chamber surrounding the assembly.  After the armature is in position with the commutator bars adjacent the probes, the hollow chamber is pressurized, causing the membrane to uniformly and simultaneously push on each actuator, so that each support block and the probes carried thereby move uniformly and simultaneously toward the commutator, until the probes touch the commutator bars. Testing can then be carried out, after which the hollow chamber is depressurized, allowing the support blocks and their probes to return to the neutral position under the influence of the spring arms.  By providing a socket in the test station for receiving the assembly, one can provide a system that can test armatures of different sizes by inserting different sized assemblies in the socket.

Patent CA-2221330-A1 (CA)
Inventor: EGGERS PHILIP E
IPC: A61B18/12
Filed: 1996-05-30
Abstract: An electrosurgical probe (10) comprises a shaft (13) having an electrode array (12) at its distal end and a connector (19) at its proximal end for coupling the electrode array to a high frequency power supply (28).  The shaft includes a return electrode (55, 56) recessed from its distal end and enclosed within an insulating jacket (18). The return electrode defines an inner passage (83) electrically connected to both the return electrode and the electrode array for passage of an electrically conducting liquid (50). By applying high frequency voltage to the electrode array and the return electrode, the electrically conducting liquid generates a current flow path between the target site and the return electrode so that target tissue may be cut or ablated. The probe is particularly useful in dry environments, such as the mouth or abdominal cavity, because the electrically conducting liquid provides the necessary return current path between the return electrode and the target site.

IPC: H04M11/00
Filed: 1998-01-13
Abstract: When a teleconference among more than two places is performed using a multi-point teleconference system, each of teleconference terminal units makes a connection to a multi-point control unit by line. When the number of participants in the teleconference reduces during the teleconference so that the teleconference is performed between only two places, a conference state managing section requests the two teleconference terminal units to make a point-to-point-connection. When the point-to-point connection is acknowledge by these teleconference terminal units, the teleconference by the multi-point control unit is finished. Thereafter, the line is automatically connected between the two teleconference terminal units to perform a teleconference in the style of the point-to-point connection, so that a fee paid for use of the line is one-half compared with that in the case of the prior art.
Patent CA-2228227-A1 (CA)
Title: Dynamic gain control system for optical amplifier and method thereof
Inventor: VAN DER PLAATS JOHANNES CHRIST
IPC: H04B10/17
Filed: 1998-01-27
Abstract: The dynamic gain control system includes a pump source providing pump light. The dynamic gain control system measures a certain portion of the input pump light into the optical amplifier and measures a certain portion of the output pump light from the optical amplifier. The dynamic gain control determines the pump light loss based on the input pump light and output pump light measurements. Based on the pump light loss, the dynamic gain control system maintains the pump light loss relatively constant (for example 0.1 dB) independent of the number of input channels and their relative powers (for example, input channel powers of-50 dBm to 10 dBm) by providing feedback to control the output pump light. In doing so, the dynamic gain control system maintains the inversion level of the optical amplifier. A relatively constant inversion level corresponds to only small variations in the gains of the input channels (multi-channel gain) as a result of changes in the input channels to the optical amplifier.

Title: Pager based monitoring
Inventor: HAMILTON DOUGLAS R
IPC: H04W84/02
Filed: 1998-03-31
Abstract: A remote monitoring system uses a bi-directional pager communications system for monitoring remote monitoring stations. Each remote station includes monitoring hardware, data storage for recording data collected by the monitor and a pager for transmitting the data to a user through a commercialpager system. The pager also receives control signals from the user. The remote station may include control devices for altering the monitoring process or varying other operating parameters. As a data communications system, the bi-directional pager or digital cellular PCS modem can be mated to most any monitoring device. This allows for inexpensive monitoring because the need for frequent visits to the remote site is eliminated. Where a monitored site is not within an area covered by a host pager service, a mobile pager host is used as an intermediary for collecting monitoring data and delivering control data.
