Title: Miniature high resolution viewscreen cantilever i.c.
Inventor: TULI RAJA S
IPC: G02B26/08
Filed: 1993-04-16
Abstract: ABSTRACT          A miniature single monolithic chip is to be used to create a viewscreen for computers, television or video applications. The image is formed by the bending of individual cantilever arms configured in a two dimensional array. The bending is activated with heat caused by the application of electricity on a heating or piezoelectric element which has been deposited on the arm. Advantages of this system are higher contrast, greater viewing angle, and capablity of being reflected onto another viewing surface.

Title: Film deceleration unit
Inventor: SHAW WILLIAM C
IPC: G03B1/42
Filed: 1991-08-12
Abstract: A projector having a rolling loop film transport mechanism is provided with a film decelerating cam unit (52) that is located in adv-ance of the aperture of the projector. Deceleration pins (66) carried by a pair of verti-cally spaced arms (62) that project from the cam unit, en-gage in upper and lower mar-ginal perforations in the film and travel with the film tow-ards the aperture and deceler-ate the film as each frame is advanced. The cam unit in-cludes two cams (56, 58), one of which causes the decelerat-ing motion of the pins, and a return motion in the reverse direction, while the other cam (58) causes the pins to adv-ance and retract into and from the film path respective-ly. By positively retracting the pins, their return movement against the direction of film travel can take place independent of the motion of the film. As compared with the prior art, acceleration forces and resultant stresses on the cam are reduced and the cam unit can operate at higher frame rates and/or with smaller rotor gaps.

Title: Method and apparatus utilizing static imbalance to reduce vibration caused by tire/wheel assemblies and tire/wheel assembly made using same
Inventor: BEEBE JAMES C
IPC: G01M1/32
Filed: 1992-04-22
Abstract: METHOD AND APPARATUS UTILIZING STATIC IMBALANCE TO REDUCE VIBRATION CAUSED BY TIRE/WHEEL ASSEMBLIES AND TIRE/WHEEL ASSEMBLY MADE USING SAME       Abstract of the Disclosure The mass of a tire/wheel assembly is altered to apply  a static imbalance to the assembly in a manner  which  reduces the  overall  tendency  of  the assembly to cause vibration in the plane perpendicular to its axis of rotation when in use.   The applied imbalance,   combined  with   any   static   imbalance initially inherent in the tire/wheel assembly, results in a desired net static imbalance oriented so as to induce  a  centrifugal  force  which  opposes,   and, therefore tends to cancel,  at least one component, such as  the  first order harmonic,  of radial  force variation characterizing the assembly.  The magnitude of the net static imbalance is limited and is prefer-ably selected to substantially equal the lesser of either:  (a) a predetermined maximum limit, or (b) the amount of static imbalance required to generate at a designated highway speed a centrifugal  force whose magnitude substantially equals that of the aforemen-tioned radial force variation component.

Patent CA-2107697-A1 (CA)
Inventor: WALSH JOHN T
IPC: F16K35/16
Filed: 1993-10-05
Abstract: A fluid pressure, operated piston engine assembly, such as a pump assembly, including a fluid pressure operated piston engine and a fluid valve for coupling fluid under pressure to alternative portions of the piston chamber of the piston engine.      The fluid valve includes a valve spool which is translated to effect the alternative modes of coupling pressurized fluid to the piston chamber.      The translation is accomplished by a shifter assembly having a shifter rod attached to the valve spool. The shifter rod includes a pair of diametrically opposed magnets attached thereto. A fork is attached to the piston engine drive shaft at one end and is mounted for limited movement along the shifter rod between the pair of magnets of the shifter rod. The interaction between the flux generated by a magnet carried by the fork with one of the magnets of the shifter rod causes the shifter rod, and in turn the valve spool, to shift from one position to another, thereby re-directing the flow of fluid to the piston chamber to effect the reversal of direction of travel of the piston and its associated drive shaft.

Abstract: A variable message display sign having a power source and comprises a plurality of character displays each having signal elements organized in distinct sets, each said signal element having an on state and an off state. A controller located remotely from the character displays produces an address signal containing character address data for identifying an addressed character display, a set signal containing set address data for identifying an addressed set of signal elements and a data signal containing display data corresponding to desired on/off states for each signal element in the addressed set. A logic circuit associated with each character display has a unique character address therefor, each logic circuit located proximately to a respective one of the character displays and having a memory operative in response to an address signal containing character address data corresponding to the unique character address of the logic circuit to receive and store the display data according to the set address data for an addressed set of signal elements. The logic circuit is operative to switch the signal elements of its associated character display to a desired pattern of on/off states according to the display data stored in the memory thereby to display a desired character. A data bus interconnects the controller and the logic circuits whereby the character address data, the set address data and the display data are communicated to the logic circuits.

Patent CA-2128271-A1 (CA)
Inventor: CASSIDY GERALD A
IPC: G07D11/00
Filed: 1994-07-18
Abstract: A system for the secure transportation of articles such as cheques and bank notes comprises first and second docking stations at different locations, and a secure container which mates with the docking stations. The container has a number of lockable doors into which bank notes are fed by a feeder mechanism at the first docking station. The container has its own microcontroller which monitors the status of the doors and the integrity of the container, and which can respond to external control signals while it is in transit. Once the container has been loaded at one docking station, it is transported to the second docking station at a different location, where it can be unloaded. A one-time code is generated each time the container is loaded, and must be communicated to the second docking station before the container can be unloaded. Any attempt to tamper with the container while it is in transit results in the activation of a dye dispenser, which marks the contents of the container.

IPC: B65G15/30
Filed: 1994-07-28
Abstract: ABSTRACT    A conveyor mat built up of plastic intermediate modules and end modules, each module consisting of a plurality of equally spaced-apart hinge plates having hinge loops at the two ends thereof, the hinge plates of a module being coupled to each other by means of a rib asymmetrically located between the hinge loop openings which are located opposite each other, the ends of the hinge plates on a longitudinal side of a module being located between the ends of the hinge plates of a module adjacent in the longitudinal direction of the mat, the hinge loops of the two modules being coupled to each other by means of a hinge pin extending through the hinge loop openings. In operation, when the conveyor mat is driven in a first and second, opposite, direction, a sprocket wheel meshes with a side face of the rib and, respectively, the opposite hinge loop of a module. Through these measures, a conveyor mat is obtained whose modules can have an extremely slight length, up to 0.5".
