Patent CA-2237740-A1 (CA)
Inventor: DHURUVASANGARY VEERASINGHAM
IPC: G04G9/00
Filed: 1998-06-25
Abstract: Clocks are used to tell time. There are clocks with 24hrs (1 Rev./day) and l2hrs dial (2 Rev./day). Currently very expensive clocks are used to see the time at different locations, other than that number of locations or countries is very limited. The clocks, as well as the dials, are flat. This means that are incapable of accommodating all the countries name.  Apart from the above noted disadvantages, existing clocks require a minimum of two adjustments per year i.e., one at the start of the spring season for Daylight Saving Time and the other at the end of the fall season for back to Standard Time. It is also very difficult to find time for different locations on the earth's surface or countries especially under dim light conditions. In this invention the clock is made with spherical or cylindrical configuration to accommodate large number of locations or cities as many as 4000-5000. Additionally major cities could be illuminated with a melody for one minute as required. In addition to correctly identifying a location, or a country and its time as well as daytime or night-time of that location, the location could be found even in extremely dim lighting. This is achieved by a special circuit which will make dial and map to illuminate at desired light intensity This product, the "World Clock" has numerous practical uses. First, it is an excellent educational tool for teaching children about different time zones, the earth's movement, and the occurrence of day and night etc. Moreover, this product is ideal for travel agents, international airports and various other institutions. As major cities are illuminated with light emitting diodes this clock also has ornamental value too. Due to above said facts this invention /  product would find world wide market in the near future.

Abstract: L'administration locale, concentrée, directe d'anticorps, et notamment d'un pool d'immunoglobulines humaines, sur des surfaces tissulaires (telles que des plaies, des brûlures, etc.), et sur des surfaces d'implants de biomatériaux ralentit considérablement l'infection sur ces sites et améliore la cicatrisation. Les immunoglobulines servent à opsonizer les agents infectieux circulant en vue de favoriser leur phagocytose et leur élimination, avant adhésion microbienne et formation d'un biofilm, et de neutraliser les toxines bactériennes. Cette méthodologie de traitement entraîne une réduction des inflammations, du complément et des lésions tissulaires ainsi que du rejet des biomatériaux et des transplants.

Patent CA-2245019-A1 (CA)
Inventor: LEWIS ROGER
IPC: B60T17/22
Filed: 1998-09-24
Abstract: The present hostler control of a computer control train brake system combines the computer control of the train and locomotive brake system with a manual control during a hostler mode to provide soft and safe operation of the vehicle. Interlocks provide efficient and safe transferring of the controls between the computer control brake system and the manual hostler control portion.  The computer control train brake system includes an electropneumatic brake controller which automatically applies the independent brake once the hostler lead mode is determined.  Next, the brake controller charges the brake pipe to release the train brakes.  Control of the independent brake is transferred to a pneumatic independent brake control valve of the hostler stand after the brake pipe has been charged sufficiently to fully release the train brakes.  The brake pipe is charged or the train brakes are released only after the independent brake application has reached a predetermined value.  The computer controls the locomotive brakes in response to the pressure of the independent brake pipe and brake pipe.  When the operator deactivates the hostler control, brake control is automatically transferred back to the computer control.

Title: Magnetic centrifugal clutch
Inventor: LAMB KARL J
IPC: H02K49/04
Filed: 1997-03-13
Abstract: A magnetic coupling device has an electroconductive rotor (15) presenting a band (16, 17) of electroconductive material and has a magnet rotor (14) with permanent magnets (26) which are slide-mounted to move radially outward responsive to centrifugal force in opposition to a spring (40) bias. When the magnet rotor is stationary the magnets are radially inward of the orbit of the electroconductive band, and when the magnets have moved outwardly when the magnet rotor is rotating, the magnets are spaced by an air gap from the electroconductive band so that eddy currents are induced in the band resulting in coupling of the rotors. The electroconductive rotor preferably has two such bands (16, 17) positioned on opposite sides of the magnet rotor. The rotors may have sheaves mounted thereon.

Patent CA-2250020-A1 (CA)
Inventor: KOPP LORENZ
IPC: C25F3/14
Filed: 1997-03-26
Abstract: The invention relates to a process and a device for the electrochemical treatment with a fluid of mutually electrically insulated electrically conductive regions (2) on items (1). Insulated, e.g. etched, structures on printed circuit boards cannot be treated electrochemically by prior art processes as there is no electrical connection between individual regions and the bath current source. According to the invention, this connection is made by means of brushes (3), the electrically conductive and thin fibres contact the structured surfaces to be treated. A large number of brushes, which are arranged transversely to the conveying direction of the items to be treated, ensure that all mutually insulated electrically conductive regions on the items to be treated are electrically contacted at least in succession and the contact time obtained is long enough. There are preferably counter-electrodes (8) between the brush electrodes which may also take the form of moving brushes. The brushes are cyclically demetallised in electrochemical processes in which metal is removed. Various methods therefor are proposed.

Abstract: The dispenser enables a multiplicity of doses of a substance in powder or granular form contained in a reservoir to be dispensed in succession. To form a dose a shaft must be rotated relative to a part of the dispenser, the shaft having to be substantially vertical while the dose is being formed.      Between the shaft and said part of the dispenser there is provided a joint which prevents relative rotation if the shaft is not substantially vertical, or which although allowing relative rotation enables a signal to be emitted which can be sensed by the user. In particular the dispenser can be a multi-dose inhaler for medicaments.
