Patent CA-2438399-A1 (CA)
Inventor: HART COLIN
IPC: A61M5/00
Filed: 2001-07-27
Abstract: An apparatus and method for manually injecting fluid into a patient with improved contrast visualization are disclosed. The apparatus includes a syringe having a cylinder in which a plunger is reciprocatingly mounted. The syringe is connected to a manifold which itself is connected to a source of radiopaque contrast. Retraction of the plunger within the cylinder draws contrast into the cylinder, and depression of the plunger forces the contrast through the manifold and into a patient through a catheter. In order to increase the speed of injection and thus the visualization of the contrast, an improved visualization device is provided which may be provided in the form of a heater or, alternatively, in the form of an expandible catheter. The heater may be positioned anywhere within the apparatus to elevate the temperature of the contrast material, which in turn reduces its viscosity and thereby increases the speed with which fluid may be injected. The expandible catheter, may be used to restrict blood flow through a vascular structure so that the contrast material may be injected into the patient with lessened resistance and dilution from blood flow.

Title: Method and apparatus for inhibiting projection of selected areas of a projected image
Inventor: VLAHOS PAUL
IPC: G03B21/60
Filed: 2002-02-14
Abstract: A video projector (6) shows the desired scene on a projection screen (3). An infrared source (7) close to the video projector uniformly floods the projection screen with non- visible infrared radiation. An infrared sensitiv e camera (5) observes the projection screen and sees only the uniform illumination of the screen. Upon entry of a subject (4) into the projected video image, the infraged reflected from the subject will not match that of the projection screen and thus the subject area is identified. All pixels of the projected scene, in the area occupied by the subject, are inhibited befo re reaching the video projector. The subject may then look directly at an audience without being blinded by the projector.

Title: System for making incisions for scleral eye implants
Inventor: SCHACHAR RONALD A
IPC: A61F2/14
Filed: 2002-02-22
Abstract: A system and method is disclosed for making incisions in the sclera (102) of an eye (100) to form a scleral pocket (120) to receive a scleral prosthesis (200). The system and method comprises a surgical tool (1100) comprising a surgical blade (1140) for making incisions in the sclera (102) of an eye (100). When a surgeon places the surgical blade (1140) on the sclera (102) of the eye (100) a pressure sensor (2560) in the surgical tool (1100) determines whether there is sufficient pressure between the surgical tool (1100) and the sclera (102) of the eye (300) for the surgical tool (1100) to operate properly. The surgeon activates the surgical tool (1100) to cause the surgical blade (1140) to advance through the sclera (102) to form an incision having dimensions to receive a scleral prosthesis (200). When the incision is complete the surgical blade (1140) is rotated back out of the incision. The incision has the exact dimensions to receive a scleral prosthesis (200).

Title: Method for regulating an electrolytic cell
Inventor: BONNARDEL OLIVIER
IPC: C25C/
Filed: 2002-02-26
Abstract: The invention relates to a method for regulating an electrolytic cell for the production of aluminium by the reduction of alumina dissolved in a melted cryolite bath. According to the invention, solidified bath talus (15) is formed on the internal walls of the tank (2) and a quantity B, called the talus evolution indicator is determined, which is sensitive to the evolution of said solidified bath talus. Subsequently, at least one of the tank regulation means (such as the anode-metal distance (H)) and/or at least one control operation (such as the addition of AlF¿3?) is modified according to the value obtained for said indicator. The indicator can be determined from electric measurements on the tank and/or from measurements in relation to the liquid metal surface. The inventive method can be used to regulate effectively an electrolytic cell having intensities that can reach up to 500 kA with an electrolytic bath having an AlF¿3? content greater than 11 % and to reduce noticeably the number of AlF¿3? content measurements taken for the bath.

Filed: 2001-05-23
Abstract: The invention relates to a tool for tensioning, slackening and opening spring- clip elements, in particular hose clips (1) which comprise actuating tabs (2, 3). Said tool comprises a Bowden cable (11), a tensioning element (12) that engages with the tabs of the clip and on the opposite side an actuating element (10) comprising a locking device (26). The tool is characterised in that the actuating element (10) and the locking device (26 to 32) are configured and co-operate in such a way that several respective, short tensioning strokes, each successive stroke being locked, are executed until the required cumulative tension stroke has been reached. The hose clip can thus be easily opened to the optimum extent using one hand, by pressing the actuating element repeatedly.

Title: Wind powered hydroelectric power plant and method of operation thereof
Inventor: MERSWOLKE PAUL H F
IPC: F03D9/00
Filed: 2002-04-08
Abstract: A hydroelectric power plant uses a plurality of windmills connected to compressed air generators to produce pressurized air. Pressurized air is use d to drive water through a turbine to produce electrical power. The water is recycled and the power plant includes reserve pressurized air tanks to allow the plant to continue to operate when the wind levels are not sufficient to produce high pressure air. The power plant is designed to be operated on a continuous basis based on wind power. When the wind subsides and the reserve capacity has been exhausted, electricity can be drawn from the local utility supplier. When excess power is generated by the power plant, electricity fro m the power plant can be added to the grid of the local electricity supplier.< /SDOAB>

Patent CA-2462943-A1 (CA)
Title: Hand grenade
Inventor: KINLEY IAN
IPC: F42B27/00
Filed: 2002-10-11
Abstract: The invention relates to an airburst hand grenade. Existing constructions of fragmentation grenades all have one basic shortcoming; the active fragments are very unlikely to find the target owing to the fact that detonation takes place with the hand grenade lying on the ground, whereby the effect does not occur. The invention solves the above problem by a hand grenade being caused to jump 1-2 m above the ground before detonating. This means that the fragments will be spread essentially horizontally and an angle (v) to the ground and consequently attack the target from above, which results in a man y times larger target surface and the capability of spreading fragments behind a shelter. The hand grenade comprises a mechanism (1), a detonator (2), a warhead (14) and support legs (9) for raising the hand grenade from a horizontal position to an upright position. The detonator (2) comprises a delay unit (3), an upper charge (4) which can release the support legs (9) b y removing a locking cover (8), a jump charge (5) which can throw the warhead (14) above the ground, and an explosive cartridge (6) which can initiate a main charge (13).
