Patent CA-2100362-A1 (CA)
Inventor: WALTER DAVID T
IPC: B02C17/24
Filed: 1992-12-15
Abstract: A motor-driven drive shaft is coupled to a grinding mill or other unbalanced rotatable member through a clutch arranged to accommodate misalignment, the clutch being so controlled during start-up as to be initially engaged to effect a first limited rotation of the mill in the drive direction, then disengaged to permit the mill to rotate under its own weight through a second rotation in the direction reverse to the drive direction and through a third rotation in the drive direction, and then to be re-engaged during the second rotation of the member in the drive direction. Clutch orbiting is thus reduced if not eliminated.

Patent CA-2109890-A1 (CA)
Title: Engine Control Method for Use with Automatic Clutch Control
Inventor: SLICKER JAMES M
IPC: B60W30/18
Filed: 1993-11-24
Abstract: A friction clutch (20) coupling an engine (10) and a gear transmission (30) of a vehicle is controlled by a microprocessor based circuit using logic which defines operating modes according to engine (10) and clutch (20) conditions.  During the time of clutch closure, when the vehicle is starting from rest in a startup or launch mode, the throttle or other engine control signal is restrained from quickly responding to the accelerator pedal  (11).          This  avoids  engine  overspeeding  which  results  from generating high torque before sufficient clutch capacity has been achieved.  The control signal is developed as a function  of the pedal  (11)  position under  control  of throttle logic which,  in turn,  is dependent on clutch operating modes defined by the clutch logic.  The clutch operating  modes  are  four  modes  for  automatic  clutch operation comprising touch point (81) approach mode which prohibits a throttle signal during initial clutch movement, creep mode or startup mode after touch point 81 occurs, and lockup mode for completing clutch closing when low clutch slip is attained.  A non-automatic mode is entered before the accelerator pedal (11) is depressed or when engine (10) stall conditions are detected.

Abstract: The subject disclosure concerns Bacillus thuringiensis strains which can be used to control lepidopteran pests. The strains were previously known to control coleopteran pests. The discovery of lepidopteran activity was totally unexpected. These B.t. strains can be formulated using standard lepidopteran formulation procedures.  Means of administration are also standard. The genes encoding lepidopteran-active toxins can be isolated from the B.t.  isolates and used to transform other microbes or plants for use to control lepidopteran pests.

Abstract: An apparatus (10) for providing a fluidized bed (12) to effect the separation of a mixture of articles (22) having a first density and a second density that is greater than the first density into separate groups. The apparatus (10) includes an inclined trough (12) which is supplied with either a fluidization on medium, such as sand, or a mixture of articles (22) from which a fluidized bed is formed by forcing gas upwardly  therethrough and through the bottom of the trough (12). Where a fluidization  medium is used, the mixture of articles (22) is introduced into the fluidized bed medium so as to be entrained therewith to effect separation as the articles travel in the direction of flow of the fluidized bed medium. Essentially  only vertical oscillatory movement is imparted to the trough to improve the separation and layering where the mixture is fluidized, or to improve the density uniformity where a fluidization medium is fluidized as the bed.

Abstract: The present invention is a portable two-way awning for use with recreational type trailer vehicles. The awning is comprised of a number of roof panels made with two sheets of aluminum surrounding a polystrene core. A hanger mechanism is bonded to each of the panels, and suspends them on an adapter rail that slidingly engages with a standard awning attachment rail. The roof panels mate together via a number of interlocking members disposed on theirmating sides. The outer periphery of the roof assembly is surrounded with a number of extrusion members. Once the roof assembly is pivoted to a nearly horizontal position, it is supported at its front end by a number of adjustable height poles, two of which swing freely into n vertical position when the roof is initially erected. The awning requires no tools or caulking to set-up, and takesless than thirty minutes to either erect or dismantle. The awning is relatively light in weight, yet strong enough to withstand the harshest of weather conditions.

Abstract: Refuse 21 in a refuse container Z is heated by a heater 16, and the steam generated from the refuse 21 is condensed by a condenser 8. The ambient temperature near the refuse container 2 is detected by a first temperature detector 6, and the output of the heater 16 is controlled by the output of the first temperature detector 6 so that the temperature near the refuse container 2 may be a specific temperature, and the temperature of the steam flowing out from the refuse container 2 into the condenser 8 is detected by a second temperature detector 7 at the condenser 8. When the temperature change of the second temperature detector 7 exceeds a specific value, the drying process is terminated, so that the drying end time can be detected accurately without allowing to scorch.

Filed: 1992-10-22
Abstract: 2122493 9309447 PCTABS00022 An apparatus and method are disclosed for detecting and locating the origin of a gamma ray in a medical diagnostic imaging system.  At least one primary fiber, which is a scintillating optical fiber, is positioned to receive radiation from a gamma ray source.  At least one secondary fiber intersects the primary fiber at a non-zero angle and is in optical contact with the primary fiber.  Both the primary and secondary fibers are provided with means for detecting light propagated in the fibers. The interaction of a gamma ray with the primary fiber will result in the propagation of light in both the primary and secondary fibers, thereby permitting the determination of the site of impact of the gamma ray in the detector, and possibly also enabling the determination of the path of incidence of the gamma ray.

IPC: B29D30/48
Filed: 1994-05-12
Abstract: A plurality of helically wound tire beads are made by winding them on a forming wheel at two predetermined tension levels. The tension levels are generated by a braking pulley and magnetic particle brake in conjunction with a programmable logic controller. The first few turns of wires are made at a relatively low tension level.      Subsequent turns are made at a higher tension level. The lower tension level contributes to longer life of the forming wheel assembly.

Title: Downdraft velocity estimator for a microburst precursor detection system
Inventor: RUBIN WILLIAM W
IPC: G01S13/95
Filed: 1992-12-16
Abstract: A weather surveillance apparatus utilizes a set of beams (1a, 1b; 2a, 2b; 3a, 3b) in an elevation angular sector (0 1; 0 2; 0 3) one beam being offset from the other by a predetermined offset angle. Radar signal returns in each beam are processed to establish an average doppler frequency shift for the signals in the respective beams. An average of the averages and a differ-ence of the averages are determined which are utilized to establish horizontal and vertical wind velocities. These velocities are further processed to determine whether a microburst precursor exists and the location, magnitude, time to impact, and track of any resulting windshear.

Title: Automatic Cycle Terminator for Dryers
Inventor: HART DOUGLAS R S
IPC: D06F58/28
Filed: 1992-12-10
Abstract: A control device is constructed in the form of a plug adaptor and a control means that can interrupt the power to a dryer when the load is dry. The pattern of the power consumption of the dryer is used, together with a control algorithm, to provide the information needed for the control decision. The device provides a superior means of determining the cycle termination point which could also be incorporated directly into dryers at the point of manufacture. In addition, the invention provides a means of correlation between the moisture level and character of the laundry load with the pattern of power consumption of the clothes dryer. This correlation may be used to further optimize the performance of the drying cycle or to provide load-specific control and termination procedures.
