Patent CA-2208540-A1 (CA)
Inventor: SAVA LUCIAN FLORIN
IPC: B60C23/00
Filed: 1997-06-17
Abstract: In the automotive area it is well known the importance of tire pressure. Incorrect air pressure in tire can: (A) Make steering of a vehicle difficult and possibly generate accidents. (B) Increase fuel consumption and pollution. (C) Cause excessive tire wear. Tire pressure cannot be accurately estimated by looking at tire, especially if it's radial. Some drivers do not check the pressure in the tire. It takes time and effort to pick up a gauge and check the pressure in all tires. My invention is simple and will give drivers an indication of pressure in a tireat a glance. My new "Pressure Checker" will be permanently left on the tires valve and will show when tires are over or under inflated. This tool will not give a numeric value for the pressure. It will help drivers to know when it's the time to go to a compressor and inflate a tire. From my own experience many drivers ask me if I have a gauge to check the pressure in a tire because they think that the pressure is not good. Sometimes the pressure is correct sometimes not. With this innovation drivers will be able to determine at a glance when it is necessary to have their tire pressure adjusted. My innovation will look like a valve extension. When it is screwed onto the valve it will allow air pressure from the tire to pass into the pressure indicator. The air will move a plunger with a sleeve against a spring in proportion to tirepressure. The sleeve will be coloured in two colours, blue for over inflation and red for under inflation. The sleeve will be visible because it will move inside a clear cylinder. The division between the two colours will match an index line on the clear plastic cylinder showing when the tire pressure is correct. My new "Pressure Checker" will be made for various pressure ranges to accommodate the pressure specification for different vehicles as required by the car owner's manual. The device could be used for example by cars, trucks, tractors and other vehicles. The convenience of this type of reading will alert drivers to unsuitable tire inflation so they may have it corrected. I emphasise the simplicity of this kind of reading. Everybody can do it. This will make it easier for drivers with little technical knowledge.

Title: 800 number call back
Inventor: KESHAV SRINIVASAN
IPC: H04M3/51
Filed: 1997-07-16
Abstract: A method and system for handling incoming calls when no destination stations are available. When an incoming call from an originating station is received, it is determined  whether a destination station is available. If a destination station is not available, a telephone number of the originating station is stored, Shortly before its current call is concluded, a destination station indicates its approaching availability. Responsive to this indication, an outgoing call is placed to the originating station. If the originating station does not answer the outgoing call within a predeternined time, the outgoing call is terminated and rescheduled. If the originating station answers the call within apredetermined time, the outgoing call is connected to the available destination station.

Filed: 1996-02-05
Abstract: A clamping apparatus (35) for detachably connecting a tool unit (10) to a tool supporter (37) with increased holding force is provided. The clamping apparatus (35) includes a housing (41), a pair of opposing locking spheres (57a, b) within the housing (41), a cylindrical canister member (39) mounted within the housing (41) that is matable with an insert-supporting tool unit (10) and which has a pair of opposing apertures (55a, b) in its sidewalls for conducting the locking spheres (57a, b) from a locking to an unlocking position, and a lock rod (60) reciprocally movable within the interior of the canister member (39) along an axis (A) and having opposing cam portions (64a, b) for radially moving the locking spheres (57a, b) through the canister apertures (55a, b) into wedging engagement with opposing angled walls (30) of sphere receiving openings (20) in the tool unit (10). To increase the mechanical advantage of the wedging action between the locking spheres (57a, b) and the angled walls (30) of the tool unit (10), the aperture walls (56) of the canister member (39) are angled with respect to a line (R) extending radially from the lock rod axis (A) to reduce the angle between the aperture wall (56) and the tool unit wall (30). Such angling increases the force of wedging and locking engagement between the locking spheres (57a, b) and the angled walls (30) of the tool unit (10). In the preferred embodiment, the aperture walls (56) are angled 15~ with respect to the aforementioned radial line (R), thereby increasing the holding force of the clamping mechanism (35) by 30 %.

Abstract: A painting wagon (20) for carrying a plurality of components to be painted through a painting facility is disclosed. The wagon (20) includes a component supporting assembly (50) having a plurality of opposed pairs of component mounting pins (66) fixed thereto.

Title: High energy laser focal sensor
Inventor: LIVINGSTON PETER M
IPC: B23K26/04
Filed: 1998-04-20
Abstract: A   sensor  having   an   interferometer,   and   a corresponding method,  for use in the sensing of focal shifts in high energy laser beams are provided.   The interferometer includes optical elements for generating a  reference  beam  with  a  known  wavefront  phase curvature.   In a preferred form of the invention, the reference beam is dithered and recombined with a sample beam, to produce a time-varying interference pattern indicative of the focal shift in the high energy laser beam.   The interference pattern is focused by a lens onto  a  detector  that  produces  electrical  signals indicative of the detected interference pattern.   The electrical signals are synchronously detected to remove the   dither-frequency   component,   integrated,   and amplified to generate a focal shift correction signal.          The focal shift correction signal is then applied to an axially adjustable lens positioned to effect phase curvature changes in the reference beam wavefront to match  those  of  the  sample  beam.   The  focal  shift correction  signals  generated  by  the   sensor  are indicative of the high energy laser beam focal shift, and may be used for purposes of correcting these focal shifts.

Title: High fidelity vibratory source seismic method with source separation
Inventor: ALLEN KENNETH PAUL
IPC: G01V1/37
Filed: 1997-09-19
Abstract: A method of separating the effects of the earth response on vibratory energy from individual ones of multiple vibrators (Va-Vd) to geophones (G1-G5), in generating a seismic survey, is disclosed. According to the disclosed method, measurements of the actual vibrations generated at the source are made, in addition to the geophone measurements of the refracted and reflected vibrations, both over a number of frequency sweeps. The source (Va-Vd) and geophone (G1-G5) vibrations are first transformed into frequency domain representations, by way of Discrete Fourier Transforms. An inverse matrix of the recorded frequency-domain source vibrations is then generated for each frequency. When the number of sweeps equals the number of vibrators (Va-Vd), the inverse matrix is merely the multiplicative inverse of the source measurements; if the number of sweeps exceeds the number of vibrators (Va-Vd), the inverse matrix is the generalized inverse of the original matrix. The inverse matrix for the frequency is applied to the recorded geophone vibrations at that frequency, to derive the transfer function (ha-hd), corresponding to the earth response, for each vibrator-geophone path in the survey. A weighing factor may be used to discount the effects of poorly behaved sweeps, and may be based on the ratio of the maximum and minimum eigenvalues for the inverse matrix. Using the derived transfer functions (ha-hd), an earth reflectivity function may be derived for each vibrator-geophone path by applying a minimum phase filter to the separated vibrator-geophone transfer function over frequency.
