Title: For driving step motors without overshoot
Inventor: BUNYARD MARC R
IPC: H02P8/10
Filed: 2000-10-13
Abstract: A method and apparatus for driving a stepper motor such that when the motor is stepped, the velocity of the motor is substantially zero upon reaching a new  stepped position, thereby eliminating overshoot and ringing, and the wasted energy associated with these effects. The method comprises energizing at lea st one of the stepper motor windings at a predetermined current level for a predetermined step time, wherein the current level is determined as a functi on of the step time and dynamic single-step response characteristics of the stepper motor and load so that the motor velocity is substantially zero when  the adjacent stepped position is reached. At this point, the stepper motor windings that were energized to make the rotor of the motor move are de- energized, whereupon the rotor is held in place by the inherent detent torqu e of the stepper motor. Since the velocity of the motor is substantially zero when the adjacent stepped position is achieved, there is no overshoot, and thus ringing is eliminated.

Title: Cyclone dust collector for preventing backflow
Inventor: OH JANG-KEUN
IPC: A47L9/16
Filed: 2002-05-29
Abstract: A cyclone dust collecting apparatus of a vacuum cleaner has: a cylindric-type cyclone body for centrifugally separating an air drawn into from an outside through a suction pipe and discharging a clean air through a discharge pipe; a dust collector disposed at a lower part of the cyclone body in order to collect a dust centrifugally separated from the air; and a plurality of dust backflow and rotation prevention members protruded from a bottom of the dust collector for a predetermined length in order to prevent the dust collected at the bottom of the dust collector from being flown.      According to the cyclone dust collecting apparatus of the vacuum cleaner having the above construction, the flow of the dust collected at the bottom of the dust collector is prevented, and the dust is not discharged through the discharge pipe, thus the dust collection efficiency of the cyclone dust collecting apparatus is improved.

Title: Band saw blade having reduced noise and uniform tooth loading characteristics
Inventor: CRANNA MARK T
IPC: B23D61/12
Filed: 2000-11-03
Abstract: A band saw blade (10) having relatively extended pitch patterns of eight or more teeth exhibits relatively low noise and vibration during cutting operations, and uniform tooth loading characteristics. The band saw blade defines set patterns within each pitch pattern, and each set pattern is defined by an unset leading tooth (12, 18) followed by offset trailing teeth (14, 16, 20, 22, 24, 26). Each tooth within each set pattern defines a pitch ("P") between the respective tooth and the preceding tooth in the cutting direction of the saw blade, and an accumulated pitch between the respective tooth and the preceding tooth of like set. The ratio of pitch to accumulated pitch for each tooth within each set increases from one tooth to the next, in the direction opposite the cutting direction of the saw blade.

Patent CA-2399130-A1 (CA)
Inventor: HAASE MARK CHRISTOPHER
IPC: E21B47/12
Filed: 2001-02-09
Abstract: A method and apparatus for communicating a desired target signal along a piping structure is provided. Because of the lossy communication path presented by the piping structure, an input signal, which is transmitted from a first location on the piping structure, is consciously predistorted prior to transmission. The amount and nature of the predistortion applied to the input signal is determined by mathematically modeling the communication path between the first location and a second location. Predistortion of the input signal results in reception of an output signal at the second location that closely approximates the desired target signal. Application of this predistortion method of communicating is described in the context of communicating in the borehole of a petroleum well.

Abstract: The invention relates to a teat rubber for a substantially undeformable milking cup sleeve (40) for forming a two-chambered milking cup, by means of  which milk is extracted from a teat in a suction milking process through a milking vacuum during a suctioning stroke and the teat is massaged during a relief stroke, wherein the teat rubber comprises a head part (12) that is substantially rotationally symmetrical relative to its longitudinal axis and  a shaft part (14) that is connected to the head part (12) by means of a transitional part (22), wherein the shaft part (14) is flexible, it surround s the teat and reacts to the alternating changes in pressure during the suctioning and relief strokes by changing its form. The head part (12) is embodied as an annular tube (16), which forms an insertion hole (18) for the  teat (Z), and which ensures sealing relative to the milking vacuum and the best possible grip of the teat rubber to the teat without excessively contracting the teat both during the suctioning and the relief strokes. The annular tube (16) is configured in such a way that an annular hollow space (30) is defined by the teat, the transitional part (22) and the annular tube  (16) once the teat in introduced into the shaft part (14). The diameter insi de the annular tube (16) is smaller during the suctioning stroke than the diameter inside the area of the shaft part (14) provided for the teat. The annular tube (16) is so flexible that its inner diameter can be enlarged radially outward during introduction of the teat and its axial length can be  changed.

Title: Manufacture of oral dosage forms delivering both immediate release and sustained release drugs
Inventor: SHELL JOHN N
IPC: A61K9/22
Filed: 2003-01-30
Abstract: A method is disclosed for manufacturing a pharmaceutical tablet for oral administration, the tablet combining both immediate-release and prolonged-release modes of drug delivery and using an immediate-release drug that is either insoluble in water or only sparingly soluble and is present in a very small amount compared to the prolonged-release drug. The method involves the use of particles of the immediate-release drug that are equal to or less than 10 microns in diameter, applied as a layer or coating over a core of the prolonged-release drug, the layer or coating being either the drug particles themselves, applied as an aqueous suspension, or a solid mixture containing the drug in admixture with a material that disintegrates rapidly in gastric fluid. The result in both cases is a high degree of uniformity in the proportions of the immediate-release and prolonged-release drugs, uniformity that is otherwise difficult to achieve in view of the insolubility of the immediate-release drug and its relatively small amount compared to the prolonged-released drug.
