Patent CA-2126868-A1 (CA)
Title: Electronic Control for Turf Maintenance Vehicle
Inventor: LONN DANA R
IPC: G06F11/32
Filed: 1992-12-17
Abstract: The present invention provides for an automated clip control device for maintaining a predetermined clip at varying ground speeds, heights of cut, and other changed conditions. The reel speed of the mower 10 is controlled based upon a feed-back control loop, using as input the ground speed of the mower 10, the actual speed of the reel 48, 50, and 52, the number of blades on the reel, and height of cut, among other factors. A microprocessor 102 uses control process equations to determine the duration of an output pulse width modulated signal which is provided to a valve 702, 706 controlling hydraulic fluid flow to the reel motor 71-75. The target value of the reel speed is determined by reading the desired height of cut value and the number of blades per reel, and then going to a look-up table which contains optimized "linear distance traveled per time grass is cut" values. Once the appropriate look-up table target value is found, the target reel speed is determined by finding the product of the number of blades on the reel times the target clip times the ground speed times a constant (to correct for units).

Abstract: The possibility of passing off apparent "good" higher level digital signals that may include corrupted or failed lower level digital signals because of inter-ring grooming of the lower level digital signals from a bidirectional line-switched ring to a path-switched ring and vice versa which employ first and second shared nodes is minimized by dual feeding communications circuits from the bidirectional line-switched ring to the path-switched ring and vice versa via the shared nodes. An inter-ring groomed communications circuit is provisioned from a secondary ring node in the line-switched ring of one of the shared nodes (secondary communications circuit) to be supplied to a primary ring node in the other of the shared nodes of the line-switched ring. A replica of the secondary communications circuit is demultiplexed to obtain the lower level digital signals, which are evaluated on a pair-wise basis with corresponding lower level digital signals from the primary ring node. The least corrupted of the evaluated lower level signals are selected to be combined into a new primary communications circuit which is to be inserted in the line-switched transmission path. An inter-ring groomed communications circuit is provisioned from a secondary ring node of one of the shared nodes in the path-switched ring to be supplied to a primary ring node in the other shared node of the path-switched ring. The secondary communications circuit is demultiplexed to obtain the lower level signals which are evaluated on a pair-wise basis with lower level signals from a corresponding primary communications circuit to determine which of the lower level signals are least corrupted. The selected least corrupted lower level signals are combined into a new primary communications circuit which is then dual fed in the path-switched ring primary ring node.

Title: Thermoformable conductive laminate and process
Inventor: ENLOW HOWARD H
IPC: C08J7/04
Filed: 1993-05-24
Abstract: A process for making a thermoformable conductive plastic laminate for use in making plastic parts adapted for electrostat-ic spray painting of a uniform high quality paint finish includes forming a matte release coated casting sheet (20), casting an elec-trically conductive polymer (24) in thin film form on the casting sheet, drying to form a conductive primer coat (24), and transfer-laminating the conductive coating to a thin, thermoformable plastic face sheet (26). The matte release coat (20) has fine particu-late filler that transfer a micro-roughened matte surface to the conductive primer coat (24). The conductive primer (24) includes a polyester resin containing a fine particulate conductive material such as carbon black and, preferably, an anti-blocking agent such as fumed silica.

Patent CA-2142971-A1 (CA)
Title: Method and apparatus for generating high energy acoustic pulses
Inventor: WALTER BRUNO HARTWIG
IPC: G01V1/133
Filed: 1993-08-25
Abstract: A method and apparatus are disclosed for generating intense acoustic pulses by means of the water hammer effect. The method involves generating a water hammer in a conduit by suddenly interrupting a high velocity flow of fluid through the conduit. The kinetic energy of the fluid flowing in the conduit is converted into a high pressure pulse which propagates along the conduit away from the point where the fluid flow was interrupted. The high pressure pulse deforms the wall of the conduit so as to radiate acoustic energy away from the conduit into a fluid medium surrounding the conduit. The relative amount of energy dissipated in the form of mass flow in the surrounding fluid and acoustic energy in the surrounding fluid can be adjusted by changing the characteristics of the conduit wall. The direction in which acoustic energy is radiated into the fluid medium surrounding the conduit can be set by making the conduit wall asymmetrical or by bending the conduit.  Embodiments of the invention for acoustic cleaning, viscosity reduction in fluids and acoustic sedimentation are disclosed.

Abstract: A system and method which can complete a call to a specific Inmarsat subscriber ship. When a call arrives at a gateway switch, a test is made to determine if the called ship is in the gateway's local database. If it is, then a current region code is retrieved from the database and substituted for the dialed code for callprocessing.  A call is then placed to the ship.  If the call can be completed, the call is processed normally. If the call cannot be completed because the ship cannot be located in the selected region, then the call is automatically retried to each of the other regions, in a predetermined order. The local database in the gateway switch will be updated whenever a call is completed whether the call was originated or terminated at the mobile terminal.

Abstract: Board of lignocellulose-containing material and a method of manufacturing such board. The material is disintegrated to particles or fibres, dried, glued prior to or after the drying, formed to a mat and finally dried by hot pressing to a finished board. According to the invention, the lignin is modified chemically at least in the surface layer of the particles or fibers prior to the final drying, so that an increased binding reactivity is obtained by the introduction of hydrophilic groups and so that the softening temperature of the lignin is lowered. Thereby the lignocellulose material in the board is partially sulphonated so that the organically combined sulphur exceeds the native sulphur content of the material but is lower than 0.4 %.

Patent CA-2165094-A1 (CA)
Inventor: HENRY CHARLES HOWARD
IPC: H01S3/10
Filed: 1995-12-13
Abstract: A new type of monolithic optical waveguide filter comprises a chain of optical couplers of different effective lengths linked by differential delays ofdifferent lengths. The transfer function of the chain of couplers and delays is the sum of contributions from all possible optical paths, each contribution forming a term in a Fourier series whose sum forms the optical output. A desired frequencyresponse is obtained by optimizing the lengths of the couplers and the delay paths so that the Fourier series best approximates  the desired response. The filter is advantageously optimized so that it is insensitive to uncontrolled  fabrication errors and is short in length. The wavelength dependence of practical waveguide properties is advantageously incorporated in the optimization. Consequently, the filter is highly manufacturable by mass production. Such filters have been shown to meet the requirements for separating the 1.3 and 1.55µm telecommunications channels and for flattening the gain of Er amplifiers.
