Title: Control system for glassware forming machine
Inventor: BRADSHAW ALAN
IPC: G05D16/20
Filed: 1993-03-08
Abstract: A control system, more especially for use in a glassware forming machine, to control movement of a driven member (12), for example carrying molten glass, between first and second rest positions, wherein the member is driven via a pneumatic valve (16) which receives control signals from a signal processing system (32) which continually receives feedback representing the position of the driven member, and responsibly thereto the control signals are produced in accordance with a repetitive algorithm determining a motion profile controlling both velocity and acceleration in such a manner that the driven member is brought to rest exactly at the required position without exceeding limiting values for acceleration.
Patent CA-2125897-A1 (CA)
Inventor: OLMR JAROSLAV J
IPC: F02M7/18
Filed: 1994-06-15
Abstract: An engine has a carburetor that includes a bowl for fuel, a venturi in which the fuel is mixed with air, and a tube for carrying fuel from the bowl to the venturi. A solenoid valve is connected to the tube to control the flow of fuel to the venturi. An engine ignition system includes a coil assembly in which electricity is generated by a permanent magnet driven by the engine passing hear the coil assembly. A transformer includes a primary winding connected to the coil assembly, and a secondary winding. A storage capacitor and a diode are coupled in series across the secondary winding and a switch couples the solenoid valve to said storage capacitor. When an operator desires to stop the engine, the switch is closed which applies electricity from the capacitor to the solenoid valve to reduce an amount of fuel flowing through the tube.

Patent CA-2133809-A1 (CA)
Title: Indirect-fired gas turbine bottomed with fuel cell
Inventor: MICHELI PAUL L
IPC: H01M8/04
Filed: 1994-10-06
Abstract: INDIRECT-FIRED GAS TURBINE BOTTOMED WITH FUEL CELL               ABSTRACT OF THE DISCLOSURE An indirect-heated gas turbine cycle is bottomed with a fuel cell cycle with the heated air discharged from the gas turbine being directly utilized at the cathode of the fuel cell for the electricity-producing electrochemical reaction occurring within the fuel cell. The hot cathode recycle gases provide a substantial portion of the heat required for the indirect heating of the compressed air used in the gas turbine cycle. A separate combustor provides the balance of the heat needed for the indirect heating of the compressed air used in the gas turbine cycle. Hot gases from the fuel cell are used in the combustor to reduce both the fuel requirements of the combustor and the NOx emissions therefrom. Residual heat remaining in the air-heating gases after completing the heating thereof is used in a steam turbine cycle or in an absorption refrigeration cycle. Some of the hot gases from the cathode can be diverted from the air-heating function and used in the absorption refrigeration cycle or in the steam cycle for steam generating purposes.

Patent CA-2161018-A1 (CA)
Title: Telecom adapter for interfacing computing devices to the analog telephone network
Inventor: NICHOLS JAMES B
IPC: G10L13/047
Filed: 1994-05-02
Abstract: A telecommunications  adapter interfaces computing devices to the analog telephone network, achieving a tightly integrated digital telecommunications link with the analog telephone network.  The telecommunications adapter takes advantage of certain host resources including, preferably, the computer's signal processor, the computer's power supply and a computer/peripheral  serial interface. System cost for digital communications  over the analog network is therefore reduced. Furthermore, the telecommunications  adapter is able to accept and deliver a digitized representation  of the analog (voice) data stream in real time, supporting both existing and future voice-band communications technologies. Finally, the invention facilitates rapid and inexpensive adaptation to the various international telephone standards.  Instead of replacing an entire modem, a relatively inexpensive  satellite processor (i.e., the telecom adapter) may be replaced instead.  Data stream synchronization is achieved between the digital data stream and a time-driven DSP task list within the computer. Wide-area communications data streams -either data or voice- obtained from analog telephone lines may therefore be conveniently manipulated and blended into the computer's sound facilities, for example.

Patent CA-2163089-A1 (CA)
Title: Nasal drug delivery composition containing nicotine
Inventor: ILLUM LISBETH
IPC: A61K47/48
Filed: 1994-05-20
Abstract: The present invention provides a nasal drug delivery composition comprising nicotine or a pharmacologically-acceptable salt or derivative thereof wherein the composition is adapted to delivery a pulse of nicotine for rapid absorption and a controlled release of nicotine for subsequent sustained absorption. The controlled release phase can be achieved by providing an ion-exchange material which will form a complex with the nicotine. The ion-exchange material may be a polymeric material such as a polysaccharide, or may be in the form of bioadhesive ion-exchange microspheres. The pulse release can be achieved by overloading the ion-exchange material with nicotine so that the composition contains some excess nicotine forimmediate release and absorption. Alternatively, some nicotine may be associatedwith a non ion-exchange material which will release the nicotine immediately on contact with the nasal mucosa, for example non-ion-exchange bioadhesive microspheres.
