Patent CA-2044123-A1 (CA)
Inventor: PERICHON PIERRE
IPC: H03K17/04
Filed: 1991-06-07
Abstract: For a preset period (2s) following application of a closing order (5), the semi-conductor (T1) of the static power switch, supplied with DC voltage (V1), is controlled by a regulating circuit (F, 8, R3) so as to operate as a current generator limiting the current to a value (100mA) much lower than its rated value (30A). A fuse (F) acts as measuring shunt. The switch can comprise a circuit breaker function. In this case, the fault detection circuit (13) measures the voltage at the terminals of the semi-conductor (T1) and supplies an opening signal when this voltage exceeds a preset threshold.

Title: Method and mechanism for the supersonic separation of droplets from a gas stream
Inventor: NASIKAS ATHANASIOS
IPC: B01J19/10
Filed: 1991-08-09
Abstract: "Method and mechanism for the supersonic separation of droplets from a gas stream"                         ABSTRACT        In the present invention separation is effected by means of a convergent-divergent nozzle, in which the divergent portion is convex.  A supersonic flow of a gas-droplets mixture is introduced into a convergent--divergent nozzle and at the throat thereof a normal shock wave occurs and results to an abrupt change in the speed and direction of gas flow, which becomes subsonic and follows the geometry of the convex divergent portion.  The droplets are inertially separated from the gas stream and two flow zones emerge, one zone free from droplets and one enriched with droplets, these two zones being subsequently separated by a separator plate,  Henceforth, a conventional subsonic separator is used to receive the liquid formed by the separated droplets, whereas the zones of gas flow being free from droplets converge to be subsequently used in any desired manner.

IPC: A61M3/02
Filed: 1991-11-14
Abstract: The cutting of tooth or bone tissue with laser radiation  is  enhanced  by  giving  the  radiation  a polarization P parallel to the surface of the tissue being cut. For enlarging a tooth canal, laser radiation is delivered via an optical fiber which is introduced into the canal and is tapered in the region of its distal end. To fill a canal, an optical fiber having a low melting point is introduced into the canal and radiation is conducted through the fiber to melt the fiber and form the filling. The fiber may be coated with a material which will be melted by the radiation and will bond to the canal wall. Fillings and coatings are formed on tooth or bone tissue by projecting toward a surface of the tissue two starting components which when combined and exposed to light of a selected wavelength undergo a photochemical  reaction to  form a calcium containing product, and causing light of the selected wavelength to impinge on the components at least partially before they reach the surface in order to create the reaction and cause the resulting calcium containing product to bond to the tissue. Bacteria on a tooth surface are destroyed by staining the bacteria to cause the bacteria to have a dark coloration, and exposing the stained bacteria to laser  radiation  at  a  wavelength  and  energy  level sufficient to destroy the bacteria.

Abstract: A retractable ramp is telescopable to a stowed position within a rearwardly open, longitudinally extending storage chamber within a cargo vehicle frame below a cargo carrying floor therein. It can be pulled from the vehicle, tilted downwardly so that its rear end engages the ground, and then its front end can be raised and connected to the vehicle adjacent the floor of the cargo compartment to serve as an unloading or loading platform for the vehicle floor. the ramp includes carriage arms pivotally connected to the ramp assembly near ~ts front end and extending forwardly into the storage chamber to connect to glides which are slideable along the chamber. A.force asserting, weight counterbalancing mechanism is pivotally connected between the carriage arm assembly and the ramp, and positioned to exert power to assist manual movement of the front end of the ramp from an initial position in which it is pulled from the storage chamber to a raised, operatively deployed position attached adjacent the ramp floor. the ramp is so positioned in the stowing chamber as it is being stowed, and as it is being withdrawn, that it virtually floats with respect to the walls of the storage chamber and does not generate appreciable frictional forces which add to the physical exertion required to stow and remove the ramp.

Filed: 1992-06-23
Abstract: An electrostatic relay essentially comprises a fixed electrode with a fixed contact insulated therefrom, a movable electrode plate with a movable contact insulated therefrom, and a fixed pair of oppositely charged electrets. The movable electrode plate is pivotally supported to a pivot so as to have a cantilever fashion or a seesaw fashion, and also to move about the pivot axis relative to the fixed electrode between two rest positions of closing and opening the contacts.  A control voltage source is connected across the fixed electrode and the movable electrode plate to generate a potential difference therebetween. The electrets are disposed adjacent the movable electrode plate to generate electrostatic forces of attracting and repelling the movable electrode plate, respectively when the movable electrode plate is charged to a given polarity.  That is, the attracting and repelling forces are cooperative to produce a torque for moving the movable electrode plates in one direction from one of the rest positions to the other.  The electrostatic relay is useful for precisely and rapidly operating of the relay.
