Title: Gas pressured needle-less injection device
Inventor: CASTELLANO THOMAS P
IPC: A61M5/315
Filed: 1996-10-09
Abstract: An improved medication delivery device is a pen sized instrument that is powered by compressed inert gas. The needle-less injector device contains pre-filled and pre-measured medication dosages. The injector device has a pre-filled and self-contained compressed gas for providing pressure to inject the medication into the skin surface without the use of a needle. The injector device has a pressure sensitive deployment mechanism which insures proper seating of the injector face against the skin surface before medication delivery is accomplished. The needle-less injector device assures safe use by inexperienced operators (including children) under adverse conditions.

Title: Dynamic traffic light, vehicle signalling display
Inventor: KASHEFY HAMID
IPC: B60Q1/44
Filed: 1996-01-23
Abstract: A vehicle signaling display device to be mounted on an automotive vehicle, so that signaling lights of the device are visible for drivers of following vehicles, includes orange or amber, red and green lights and includes a system specifically designed to count speed sensor pulses for measuring speed of any vehicle of any make and model on which the device is installed, for controlling the signaling lights in accordance with the speed of the vehicle and regardless of operation and position of accelerator pedal of the vehicle, in order to perform a set of standardized operations of the signaling lights for dynamically preventing traffic crashes.  The device (a) turns on a distinct arrangement of a number of lights of the signaling lights for indicating different ranges of the speed of the vehicle so that a red light of the signaling lights remains lit without flashing regardless of braking as advanced stop sign indicating very low speed or stationary state of the vehicle, orange lights of the signaling lights remain lit indicating low speed of the vehicle and green lights remain lit indicating forward motion with constant speed; (b)flashes orange lights whenever the speed of the vehicle is reduced by a standardized value without braking;  (c)flashes red lights whenever the speed of the vehicle is reduced by the standardized value by braking; (d) flashes green lights to indicate acceleration by the standardized value; so that as the rate of deceleration increases, the red or orange lights flash faster.
Patent CA-2241194-A1 (CA)
Title: Determination of fluid influx or efflux
Inventor: JOHNSON ASHLEY
IPC: E21B47/10
Filed: 1997-01-24
Abstract: When drilling a borehole for an oil well it is desirable to know when fluid is passing through the walls of the borehole between the borehole itself and the formation through which the borehole is passing.      It has now been discovered that useful information about the influx or efflux of fluid can be gained by observing the pressure within the borehole in the region of the drilling bit, this observation being carried out not when the drill is actually operating but when it is still (and the pipe string to which it is mounted is also still) and the drilling fluid is not being pumped; the basis for this is that the drilling fluid is thixotropic, and when not disturbed will form a gel which is capable of quite accurately transmitting the force created by moving fluids at the interface between the borehole and the earth formation being drilled through - that is inflowing or outflowing fluids - displacing the drilling fluid along the borehole, and with an efficiency far greater than previously recognized. It is this which is the present invention - a method of, and apparatus for, determining fluid inflow or outflow during drilling, by using a gelling drilling fluid whose characteristics - yield stress ~y and gelation period ~g - are known, and then, while all drilling and pumping is ceased, measuring downhole differential pressure ~P and using the observed changes therein to allow a determination of the fluid flow.

Filed: 1997-01-10
Abstract: A method of applying a treating liquid to a porous body (11), in particular a pre-baked carbon component of an aluminium production cell, such as an anode block, a cathode block or a sidewall. In this method, first the body (11) to be treated is inserted, with its part to be treated up, in the treating chamber (12). At least one sealing member (13) is then applied to the inserted body (11) in such a manner as to isolate the chamber into two parts: an upper part (14) of the treating chamber around the part of the body to be treated, isolated from a lower part (15) of the treating chamber around a bottom part of the body which is not to be treated. Next, the upper part (14) of the treating chamber is filled with a treating liquid (10) to cover the part of the body to be treated, and a vacuum is applied to intake an amount of the treating liquid into pores in the part of the body to be treated so that the part of the body to be treated is impregnated with the treating liquid. After completion of the impregnation, the sealing member or members (13) is/are released to free the body, and the treated body (11) is removed from the treating chamber.
