Filed: 1996-02-15
Abstract: Novel benzoic acid derivatives have formula (I) wherein: -X- represents C1 to C6 alkylene, C2 to C6 alkenylene or a divalent moiety having the structure -(CH2)m-Z- in which m is an integer from 0 to 3 and Z represents -O-, -S- or -NH-; -Y- represents a direct bond, C1 to C6 alkylene, C2 to C6 alkenylene or a divalent moiety having the structure -(CH2)m-Z-(CH2)n in which m and n are each, independently, an integer from 0 to 3 and -Z- represents -O-, -S- or -NH-; R represents a 5- or 6-membered carbocyclic or heterocyclic ring or a carbocyclic or heterocyclic fused ring system containing up to 10 members in the ring, which carbocyclic, heterocyclic or fused ring system may be saturated or unsaturated and may contain up to two substituents selected from lower alkyl, methoxy, halo and trifluoromethyl; and R1 and R2 are each, independently, selected from hydrogen, lower alkyl, methoxy, halo and trifluoromethyl. The benzoic acid derivates are useful as anti-inflammatory agents.
Patent CA-2212689-A1 (CA)
Title: Coin mechanism with magnetic release system
Inventor: SCHWARZLI JOSEF W
IPC: G07F9/00
Filed: 1997-08-08
Abstract: A coin mechanism is provided with a magnetic release system, for selectively unlocking the coin mechanism when a coin or token having a magnetic component is inserted. A magnet is lodged in a rocker arm which is biased to a locked position in which a latch on the rocker arm engages a rotating member, preventing the rotating member from rotating. The attractive force of the magnet on a coin or token having a magnetic component and inserted into the coin mechanism is greater than the force biasing the rocker arm to the locked position, causing the rocker arm to move toward the coin which thus retracts the latch from the rotating member allowing the rotating member, and thus the mechanism, to rotate.

Patent CA-2216194-A1 (CA)
Title: Selective damping system for harps
Inventor: CLEMENT PHILIPPE SERGE ROBERT
IPC: G10D3/046
Filed: 1997-11-13
Abstract: Harps are musical instruments with a great number of strings which are not dampened through a felt lined mechanism, as is the case in the piano or the harpsichord. Because they have to deal with so many strings, harp players are often confronted with the challenge of controlling the duration of a sound (sustain) or preventing sympathetic vibrations of strings from occurring. Harpists rely on their hands to dampen strings; however, since they also need both hands to pluck the strings, choices have to be made. So far, no satisfactory mechanical solution has been offered to help them overcome or minimize this problem. I have designed a system which addresses such problem. I have built it, and it has been successfully tested by a professional performing harpist.   Because my invention is about to be introduced to a large public of musicians and harp makers, I would be grateful if the Canadian Intellectual Property Office was to consider my patent application as being time sensitive.
Patent CA-2218833-A1 (CA)
Inventor: YAO JONATHAN YI
IPC: H01J47/02
Filed: 1997-10-22
Abstract: An ionization chamber (36) for monitoring a radiation beam includes a housing having a primary beam passageway (86) and a number of secondary beam cells (88 and 90) that are adjacent to the primary beam passageway. The primary beam passageway passes entirely through the housing. In the preferred embodiment, a large-area beam measuring electrode (54) and an array (58) of small-area beam measuring electrodes (60, 62, 64 and 66) are each coaxial with the primary beam passageway. Also, in the preferred embodiment, each secondary beam cell includes a beam measuring electrode (68, 70, 72 and 74). Because the portions (76, 78, 80 and 82) of the radiation beam that enter the secondary beam cells do not pass through the ionization chamber, these portions do not contaminate the treatment beam, allowing the beam measuring electrodes within the cells to be dimensioned and configured so as to maximize signal strength.

Patent CA-2238742-A1 (CA)
Inventor: TURCOTTE STEVEN LUC
IPC: B60K16/00
Filed: 1998-06-30
Abstract: This concept of creating power by the use of natural ram air would be a very energy saving system. The Free Power House would use the ram air that is created with the speed of the moving vehicles, boats, trailers, or aircraft and in turn use the ram air to turn a turbine which would in turn supply the energy to turn the shaft of the Power House air handling unit.   The energy that is created would be used to replace fossil fuel components in transports, and also supply energy to electric cars. When vehicles are running at a low speed an auxiliary alternator on the engine would be relayed to kick in. Once the vehicle is up and running at higher speeds the relay would shut down the alternator being energized by the fossil fuel engine and the non polluting ram air would turn the Power House air handling system.   As we all know we have seen and felt the air being moved by a transport as we pass one on the raod is very strong. It has the energy to make your car swerve and the grass and the trees blow around. All transports are crashing the air and the energy created has never been harnessed. The air deflectors that are used on most transports could incorporate a turbine as described above to create non polluting electrical energy which in turn would save on fossil fuel.
