Abstract: A low-profile and highly-maneuverable vacuum cleaner having improved functionality including a belt storage compartment located in the bottom cover of the housing. The belt storage compartment is shaped so as to allow for storage of the belt in its relaxed state.

Abstract: A roller bed that is inserted between idlers in a conveyor belt system. The roller bed includes a base plate that is oriented substantially parallel to said surface of said conveyor belt. A first side plate on a first side of the base plate is oriented at an angle to the surface of the conveyor belt to support a first side of conveyor belt and cause the first side of the conveyor belt to be angled upwards with respect to a plane of the surface. Small diameter rollers, very closely spaced, are affixed to a surface of the first side plate to support the conveyor belt and reduce friction between the side plate and the conveyor belt. A second side plate on a second side of the base plate is oriented at an angle to the surface of the conveyor belt to support a second side of the conveyor belt and cause the second side of the conveyor belt to be angled upwards with respect to the plane of the surface.

Abstract: A Coriolis flowmeter having a single flow tube surrounded by connecting rings and a balance bar whose ends are connected by the connecting rings to the flow tube. The balance bar has a thermal coefficient of expansion greater than that of the connecting rings and the flow tube. The outer circumferential surface of each connecting ring is tapered toward the axial center of the flow tube. The inner circumferential surface of the balance bar has a taper matching that of the connecting ring. The connecting ring can only partially inserted into the space between the flow tube and the balance bar when the assembly is at room temperature. Braze material is then applied to the visible ends of the surface common to the balance bar and the connecting rings as well as to the ends of the surface common to the connecting rings and the flow tube. The structure is heated to brazing temperature to braze these common surfaces.

Abstract: A slave pulsed laser stabilizes the frequency by using the master laser frequency to stabilize a cavity in the slave pulsed laser. The slave pulsed laser includes an optical modulator, a cavity, a cavity modifier, and an output generator. The cavity includes an end reflector, a laser generator, an optical injector, and an output coupler. The optical modulator receives a continuous wave laser signal that includes a carrier frequency. The optical modulator then modulates the continuous wave laser signal to generate two sidebands around the carrier frequency. The laser generator generates a first laser signal in the cavity. The optical injector then injects the continuous wave laser signal with the first laser signal. The output generator generates an output signal based on the continuous wave laser signal. The cavity modifier then modifies a length of the cavity based on the output signal wherein the cavity is in resonance with the frequency of the continuous wave laser signal.

Abstract: Yield monitor apparatus and methods for a forage processing machinery are provided. The yield monitor measures a forage yield by variously measuring a forage impingement force, a forage volume flow, a forage volume increment accumulation, or a forage processing machinery drive load. The yield measures an impeller speed. The yield monitor may generate a yield amount, with the yield amount capable of being stored and displayed to a forage processing machinery operator. Alternatively, the yield monitor may generate a groundspeed control signal that is used by the forage processing machinery to control a forage processing machinery groundspeed or other forage processing machinery parameters.

Abstract: An energy metering device includes a volumetric flow meter or mass flow meter in combination with a gas analyzer that provides telemetry regarding the constituents of a natural gas flow stream. An interpreter analyzes this information and provides a real time output corresponding to the enthalpy of combustion for the gas stream. This output is used to adjust or throttle the gas flow stream for purposes of delivering the flow stream according to a preselected parameter, which is related to desired operating conditions for a combustion device including a boiler or an engine.

Abstract: A disk drive system is disclosed that includes a disk device coupled to control circuitry. The control circuitry includes a read channel with a detector that detects a bit sequence associated with Gray codes and delays indications of the bit sequence detection to handle phase shifts. The detector generates a Gray code detection signal in response to the delayed indications. The control circuitry processes the Gray code in response to the Gray code detection signal.

Abstract: A system that provides a remote ordering system for a Coriolis flowmeter. The system is provided by a server. The server begins by receiving input flow stream parameters from a remote client computer. The server then determines flowmeter parameters from the input flow stream parameters received from the remote client computer. The server then determines at least one model of flowmeter suitable for the flowmeter parameters. The suitable models of flowmeters are then transmitted to a remote computer where a customer may then place an order for one of the models suitable for the flowmeter parameters.

Abstract: A manufacturing process that prevents stress between a titanium flow tube and a surrounding steel balance bar due to a brazing operation. A straight tube Coriolis flowmeter having a titanium flow tube is surrounded by a balance bar having separate longitudinal halves. The balance bar halves are connected to each other by an elongated side channel on each side of the balance bar halves. The elongated side channels are radially spaced apart from the balance bar halves but connected to the balance bar halves by means of tubular pegs which extend into holes in the side channels. The flow tube is joined by brazing via connecting rings to the balance bar halves and to an inner end of the pegs. The radially outer end of the pegs are inserted into the holes in the side channels and welded. Circular welds and slots in the side channels reduce axial shrinkage of the side channels as the welds cool. This prevents axial stress on the flow tube.

Abstract: A disk drive system comprises control circuitry and a disk device. The disk device transfers an analog signal representing servo data and user data from a disk device to the control circuitry. The servo data includes servo synch marks. The control circuitry processes the analog signal to generate a digital signal representing the user data. The control circuitry includes Viterbi circuitry and servo circuitry. The Viterbi circuitry interleaves and sums samples of the analog signal. The Viterbi circuitry then processes the sums using two states, an even magnet length constraint, a D=1 constraint, and a sliding threshold algorithm to generate a bit sequence. The servo circuitry processes the bit sequence to detect the servo synch marks.

Abstract: The instrument package mounting apparatus comprises an axle that serves to eliminate the need to wrap a tether line about the axle. In particular, the axle comprises a cylindrical solid configured with a slot extending from the outer surface of the axle to a substantially central axis thereof, the slot being capable of receiving the tether line. Juxtaposed to this slot and located substantially centered about the substantially central axis of the axle is a rectangular shaped interior channel that functions to receive a pinch bar comprising a substantially rectangular shaped tapered bar. The tapered pinch bar is inserted into the channel formed in the axle and operates to frictionally secure the tether line and the axle. The friction to secure the tether line in the slot, as held in place by the tapered pinch bar is generated by a compression fit formed as the tapered pinch bar is inserted into the interior channel of the axle.
