Title: Composite magnet stepper/torquer motor
Inventor: ALLWINE ELMER C JR
IPC: H02K3/28
Filed: 1994-06-06
Abstract: COMPOSITE MAGNET STEPPER/TORQUER MOTOR         Elmer C. Allwine, Jr.     ABSTRACT    A stepper motor is provided that is compact, easily manufactured, and provides high torque.  The stepper motor comprises a multi-pole composite magnet which functions as a rotor, at least one stator member which determines the angular position of this rotor, and means for positioning the rotor and the stator members on a common axis.  The composite magnet comprises two pieces, each piece having a mating member and an arc-shaped member integrally formed with the mating member.  To form the composite magnet, the mating members of both pieces are aligned on an axis and the arc-shaped members of both pieces are juxtaposed.  The first and second pieces are magnetized in opposite axial directions which results in two advantages.  First, the composite magnet provides a high area of energy conversion per unit volume, thereby significantly reducing the size of the stepper motor in comparison to prior art stepper motors.  Second, because the projections and apertures are magnetized in opposite axial directions, the magnetic poles are extremely well-defined thereby ensuring that the composite magnet provides both accuracy and high torque capability.

Title: Perforable cap for a biological specimen container
Inventor: DAYKIN VICTOR
IPC: B01L3/14
Filed: 1994-06-14
Abstract: The present invention provides for a cap for sealing a biological sample tube for use in an automated analyzer.  The cap comprises a skirt portion forming the side wall of the cap and having thread members on the interior surface of the side wall, the skirt portion having an open top with an inwardly extending rim.  The cap also includes a top portion of a flexible elastomeric material sealed to the skirt portion through engagement with the inwardly extending rim and closing off the open top of the skirt portion.  The flexible elastomeric material is selected to permit puncture by a needle or probe such that the hole formed by the puncture of the needle or probe permits passing of the needle or the probe therethrough and reseals after removal of the needle or probe.  In a preferred embodiment, the top portion also includes an upwardly extending sealing surface near the periphery of the top portion.  The sealing surface defines a cavity to the interior thereof which may be sealed against the external environment when the sealing surface contacts a planar surface.  The present invention also provides for a sample tube for use in automated sample accessioning equipment and automated clinical analyzers.  The sample tube has generally cylindrical side wall with an open top and bottom and thread members provided on the exterior of the side wall near the top.  The tube further has a cone-shaped sample holding divider located in the interior of the tube intermediate the top and bottom.  The cone-shaped sample holding divider has an angular measurement to allow for a relatively small sample volume to be utilized such that a sample probe will be able to pick up the proper analysis volume from such relatively small sample volume.

Title: Adjustable rotary drum bale cutter apparatus and method
Inventor: BERGKAMP ALAN R
IPC: A01F29/00
Filed: 1994-10-05
Abstract: Abstract of the Disclosure A horizontally oriented three sided frame is adapted to hold a round hay bale.  An endless chain driven conveyor encircles the floor of the frame to cause the round bale to rotate about a longitudinal axis thereof while simultaneously urging a portion of the perimeter of the bale against a rotary drum cutter arrayed just above the floor on one side of the frame.  The cutter chops the hay bale into individual strands for feeding to livestock.  A spacer, commonly called a concave, is pivotably attached to the frame, and is spaced from and extends longitudinally along the top of the rotary drum.  The spacing between the concave and the drum is adjustable.  By adjusting this spacing, as well as the speed of rotation of the rotary drum and the speed of rotation of the round bale via the conveyor, the length of hay strands cut by the cutter is  adjustable.

Abstract: A caller-ID telephone station having a caller-ID based directory of telephone numbers automatically adapts its directory to compensate for a change to the area code in which the telephone station is located. The caller-ID telephonestation stores the area code for all incoming caller-ID telephone numbers along with each telephone number received. The telephone station also stores its home area code. This home area code is inputted by a user during an initialization step when the telephone station is first installed, moved to a different area code or the station's locale is changed to a different area code. In response to a request from the user for dialing a telephone number entered into the directory, the telephone station compares the stored area code received as part of the caller-ID telephone number with thestored home area code and determines from this comparison whether to include or omit the received area code as part of the dialed telephone number. In one disclosed embodiment, the received area code is included in the dialed telephone number only if the received area code and the home area code are different.

Title: Method for drilling and cementing a well
Inventor: NAHM JAMES JANG WOO
IPC: C09K8/42
Filed: 1993-10-21
Abstract: A borehole is drilled utilizing a conventional drilling fluid or a drilling fluid such as one containing a cementitious component selected from blast furnace slag, a metal oxide component of an ionomer or a metal oxide component of a phosphate salt. A compatible cementitious slurry containing blast furnace slag and an activator system is then introduced into the borehole and displaced up into an annulus by direct contact with a displacement fluid. Generally, in the case of the slag-containing drilling fluid the cementitious slurry is prepared by adding additional blast furnace slag and an activator such as a sodium hydrox-ide/sodium carbonate mixture to the used drilling fluid. Similarly, in the case of the ionom-ers or phosphates, additional metal oxide component and the reactive second component can be added to the used drilling fluid to produce the cementitious slurry.
