Title: Method and apparatus for thermoforming elongate material into arcuate shapes
Inventor: KALE HEMANT D
IPC: B29C53/12
Filed: 1995-04-12
Abstract: A method and apparatus for shaping thermoformable elongate material, such as straight tube or rod, into arcuate shapes, such as helical coils, simple circular bends and the like, without kinks or sharp bends includes preforming a female mandrel with an interior forming surface of predetermined curvature, positioning the material adjacent one end of the mandrel, heating the material to its softening point prior to bending by the mandrel, moving the material through the mandrel relative to the mandrel interior surface so that the material assumes the shape of the interior surface, cooling the material so that it retains its newly formed shape, and then removing the cooled material from the mandrel.  The mandrel can be operated with reduced internal pressure so that the material is held against the interior surface of the mandrel as it is moved.

Title: Power saving method and apparatus for computer disk drives
Inventor: NELSON DWIGHT QUENTIN
IPC: G06F1/32
Filed: 1995-06-01
Abstract: A power saving method and apparatus while maintaining an operational or near-operational state for computer memory disk drives. A microprocessor implements microcode instructions to determine if a disk drive is inactive. This is done by checking a control unit through an interface to see if any files are currently opened or data is being transferred by the disk device. If no files are opened and/or no data transfers are occurring, the drive is considered inactive. If theinactive period continues for a period of time which is greater than a predetermined reference activity level, then actions are taken to reduce the rotational velocity of the drive spindle motor to its lowest operational level, or just below the lowest operational level without stopping the disk. The spindle motor is accessed by the microprocessor through a spindle motor control unit. In the case of a constant linear velocity disk drive, the spindle motor is indirectly controlled by the microprocessor sending a message to an actuator to move a data head to a track that is near the outer periphery of the disk medium. In order to maintain a constant linear velocity, the spindle control slows the angular velocity of the motor resulting in a reduction of power consumed. When it is necessary to access data again, thedrive enters an active state and the head is moved by a microprocessor "seek" command. In the case of a constant angular velocity disk drive having selectablespeeds, the microprocessor controls the motor speed directly. The microprocessor, upon determining that the disk has been inactive for a predetermined threshold period, selects a constant speed that is the lowest operation speed available. This results in a power saving mode being implemented for the disk drive. The drive is returned to normal operational speed by a microprocessor "seek" command. For further savings, the motor is stopped or "spun down" when left inactive for a longer period of time.

Patent CA-2164926-A1 (CA)
Title: Melt heating method
Inventor: YAP LOO T
IPC: F27D7/02
Filed: 1995-12-11
Abstract: A method of heating a melt containing an oxidizable substance in which a fuel isburned with an oxidant by projecting fuel oxidant jets over the melt. The fuel and the oxidant jets have a fuel jet momentum and an oxidant jet momentum, respectively. The oxidant jet produces a top oxidation layer on the top surface of the melt and such top oxidation layer has a thickness. The oxidant jet momentum is adjusted to be below a threshold momentum at which the top oxidation layer is forces aside by the oxidant jet to expose fresh melt that potentially can be oxidized and can increase the thickness of the top oxidation layer. The fuel-jet momentum is adjusted so that it is greater than the oxidant jet momentum to draw the oxidant jet towards the fuel jet and thereby forms a desired combustible mixture in a mixing layer. Additionally, the oxidant and fuel jet momentums could be adjusted so that their total momentum (the sum of their individual momentums divided by the power output developed by the burner of the fuel) were less than about 60 newtons per megawatt.

Title: Bale-accumulating trailer
Inventor: KOHNEN RICHARD
IPC: A01D90/08
Filed: 1995-12-13
Abstract: A bale-accumulating trailer is connectable to a baler for forming round bales of agricultural crop mate-rial.  The trailer includes a fixed frame having a set of ground-engaging wheels, and a dumping frame pivotably mounted to the fixed frame for movement between a bale accumulating position and a bale dumping position in response to operation of a dumping cylinder assembly.  A bale transfer mechanism functions to receive bales dis-charged from the baler and to place the formed bales onto the dumping frame.  The bale transfer mechanism includes a carriage movable between a forward position and a rearward position in response to operation of a cylinder assembly.  A bale receiver is mounted to the carriage, and is movable between a bale receiving position and an upright position in response to operation of a pair of cylinder assemblies.  The bale receiver is positioned adjacent and below the discharge of the baler when the carriage is in its forward position, so that a bale from the baler is deposited on the bale receiver upon dis-charge from the baler.  The formed bale is placed onto the dumping frame upon rearward movement of the carriage to a rearward position and movement of the bale receiver to an upright position.  Bales carried by the dumping frame can then be deposited onto the ground by tilting the dumping frame relative to the fixed frame and moving the trailer forwardly.

Filed: 1994-12-08
Abstract: An automatic computer implemented technique which may be used for identifying makers and determining the centroids of fiducial markers (40a, 40b, 40c) (e.g., cylindrical fiducial markers: attached to the head in magnetic resonance (MR) and X-ray computed tomography (CT) volume images, is disclosed.  This technique may be referred to as image space localization.  A first portion of the technique identifies many candidate voxel points (172) included in a bright area of the image which may correspond to candidate markers. A second portion of the technique selects from the identified candidate voxels a predetermined number of candidate points of the image volume that are most likely  to lie within an actual fiducial marker (174).  The centroid for each of these markers is then determined. The method finds markers whose images are of a higher intensity than their surroundings and which have a given shape and size.
