Title: Dialysis machine with safety monitoring and a corresponding method for monitoring safety
Inventor: ROSSI ANDREA
IPC: A61M1/14
Filed: 1992-12-28
Abstract: A system is provided herein for providing monitored treatment to a patient.  The system includes a dialysis unit for providing treatment to a patient. A first group of actuators is adapted for operating the dialysis unit. A second group of actuators is operative for shutting off operation of the dialysis unit when the system is set to a general safe condition. A control unit is operative for controlling the first group of actuators in accordance with set values of control parameters, set values of safety parameters, and actual values of safety parameters which have been determined using a first group of sensors. A safety unit is operatively connected to the dialysis unit and is operative for monitoring, at regular intervals, actual values of the safety parameters, and for selectively setting the system in the general safe condition. The first group of sensors is communicatively connected to the control unit and is operative for providing the control unit with information which is indicative both of the actual values of the safety parameters and of treatment progress parameters. At least a subgroup of the first group of sensors provides, through the control unit, the actual values of the safety parameters to the safety unit. A second group of sensors is communicatively connected to the safety unit and is operative for providing the safety unit with information which is indicative of the actual values both of the safety parameters and of parameters which are indicative of an operative condition of the safety unit. A third group of sensors is communicatively connected to the safety unit and is operative for providing the safety unit with information which is indicative of an actual operative condition of the first group of actuators when the system is in the general safe condition. The third group of sensors is operative for communication with the safety unit in response to the safety unit detecting a patient-endangering anomalous situation resulting from inconsistent information which has been detected by one or more sensors of the first group of sensors of the second group of sensors.

Title: Railway bogie with frame having selective deformability
Inventor: LIENARD JEAN
IPC: B61F5/14
Filed: 1992-05-14
Abstract: ABSTRACT                      Company called: USINES ET ACIERIES DE SAMBRE ET MEUSE            "Railway bogie with frame having selective deformability"                  (Invention of Jean LIENARD) The sole-bars (1) bear on the axles by means of elastic suspensions  (12) with frictional damping. The bolster (18) bears by means of elastic blocks (32) on the lower side of a window (24) made through each sole-bar.        Each elastic block (32) bears on a face (31) of the sole-bar which has, in relation to the longitudinal direction (L) of the bolster (18), an inclination (A) such that the compressive force (F) of the elastic block has a horizontal component (FHT) which pushes the sole-bar so as to bear by its reference face (26) against a conjugate reference face (28) belonging to the bolster. Thus, the sole-bars (1) are constantly returned into a favoured configuration of perpendicularity in relation to the bolster.        Use   for   effectively   combatting   parasitic deformations and sideways movements of the deformable-frame bogies.        See Figure 3.

Inventor: HESS DAVID M
IPC: G06F1/08
Filed: 1993-10-15
Abstract: The bidirectional clocking apparatus provides automatic sensing of whether a reference clock being generated by another circuit needs to be divided down to a lower frequency. If this is true, the clock is divided down to a lower frequency and sent out to other circuits requiring the lower frequency clock. If the lower frequency clock is already generated from another circuit, the apparatus accepts this clock for use by other circuits. Only one terminal is required for either sourcing or accepting this lower frequency clock signal.

Title: Endoscope for direct visualization of the spine and epidural space
Inventor: KAGAN JONATHAN
IPC: A61B1/005
Filed: 1993-04-07
Abstract: A system (10) for direct visualization of the spine includes a catheter (12) and a fiber-optic bundle (20) disposed within the catheter (12) which is connected to a light source and camera. The optical bundle is connected (26) to the proximal end of the catheter to permit rotation of the bundle relative thereto. A mechanism for deflecting the catheter tip provides a conical viewing angle (13) for the fiber-optic bundle and assists in steering the catheter through the spinal space. The mechanism includes a deflection wire (57) extending through the catheter and affixed at the distal end (83) thereof. The proximal end of the deflection wire is affixed to a sleeve (58) slidably disposed around the catheter to contact a stop surface (59) as the catheter and deflection wire are moved. The stop surface prevents further movement of the catheter causing tension in the wire between the sleeve and the wire's securement to the catheter, thereby bending the catheter tip in the direction of the securement.
