Abstract: A process and a device for the control and/or regulation of a wagon body tilt system (1) for a railed vehicle, e.g., a train. Limit values with respect to comfort are taken into consideration for this purpose. In an equivalent way, these limit values preset a comfort scale for a rail camber or tilt (.PHI.c) as desired tilt values (.PHI.desired, .PHI.des. speed, .PHI.des.  accel.) for the control and/or regulation of a wagon body (2) as relevant value based on the system limits and permit a subsequent regulation within the adjustment system (4) of the wagon body (2) only within these limits. If at least one limit value for comfort and/or parameters describing the system is exceeded, these desired tilt values (.PHI. desired, .PHI. des.speed, .PHI. des.accel.) are then adapted by taking into account this at least one exceeded limit value and are converted to adapted desired tilt values (.PHI.' desired, .PHI.' des. speed, .PHI.' des. accel.) and used to adjust the wagon body tilt systems (1). The device for implementing the process consists of a desired value adapter (11), including a simulated tilt system (7), a tilt condition limiter (8), and an inverse, simulated tilt system (10), as well as a tolerance presetting unit (9), which can be a component of the desired tilt value adapter (11). The limit values as well as parameters describing the system used to determine the adapted desired tilt values (.PHI.' desired, .PHI.' des.speed, .PHI.' des. accel.) are stored in the tolerance presetting unit (9). This desired tilt value adaptation makes it possible to avoid hitherto existing disadvantages in the control and/or regulation, e.g. lowered driving comfort, damage or early wear and tear of the tilt system.

Abstract: The present invention relates to an induction head for sensing a magnetic strip or other magnetically permeable security structures. The induction head includes an exciting coil associated with an electrically conductive concentrator, which produces a primary field and induces a responsive secondary field in the concentrator. The concentrator has an endwall and sidewalls defining a central cavity. The endwall has a narrow measuring gap dividing the endwall into two opposed sections. The sidewalls are also interrupted adjacent the measuring gap to cause a concentrated current of the secondary field to pass along the gap. This concentrated current can be monitored for a change in induction due to the presence of an elongate magnetic strip or other magnetically permeable security structure which is moved past the measuring gap.

Abstract: A forced air furnace circulation fan controller adjusts the speed of the circulation fan according to the incidence of air delivery restrictions.   Upon detecting insufficient air delivery as a function of the temperature of the furnace heat exchanger, the control system increases the circulation fan speed to increase the air delivery within the heating system. The controller utilizes fuzzy logic techniques to determine a speed adjustment for the furnace fan motor, based on the value of the furnace heat exchanger temperature. The use of fuzzy logic control allows the circulation, fan controller to provide a highly adaptive response to changes in air delivery.   The resulting balanced air delivery provides for efficient furnace operation and superior occupant comfort.

Abstract: An obstacle detecting pig for preliminary inspection of a section of a pipeline travels through the section and determines if there are any restrictions that exceed industry guidelines or that might damage other pigs that require the full bore of the pipe. In a first embodiment, a disk-shaped segmented resilient member (14) is mounted in the body of the pig. Its outside diameter is smaller by a spacing (21) than the inside diameter of the pipeline (15). The spacing is set at the maximum tolerable size of the obstacle encountered. The deformation of the member (14) is transmitted by a linkage (22) to a slider (16) activating a switch system signalling that an obstacle has been encountered. A non-resiliently deformable checkup disk (19) may be provided at the rear end of the pig, to double check that a no-signal passage through the pipe is not due to failure of the switching system. In a particularly preferred embodiment, the resilient member is a disc-shaped detector (46) made from an elastomer and provided at its leading surface with a scratch recording layer (51), for instance a layer of lead which is thin enough to follow resilient deformations of the elastomeric ring (50) as it encounters an obstacle, and return of the ring back to its regular, shape. The scratches caused on the recording layer are evaluated after the passage of the pig through the examined pipeline section. The detector is mounted directly on a slider (44) or the like operating device designed to produce electric signal when an anomaly is encountered. Preferably, the detector (46) is a replaceable element of the pig. The device is structurally simple thus providing low manufacturing and operation costs and simple operation.

Abstract: A kit of cord grip components which when applied to an electrical cord provide a strain-relieved, water-tight cord grip. A body having a bore with a tapered end wall and external thread portion receives a deformable bushing having a matching tapered portion. An assembly device having a second tapered end wall and an internal threaded portion receives a grip device having a plurality of displaceable fingers. When the assembly device is threaded onto the body, the deformable bushing is compressed upon a cord inserted in the cord grip to provide a water-tight seal and some strain relief while the displaceable fingers of the grip device securely grip the cord to provide the major portion of the strain relief. By changing the bushing and grip device, to ones having different diameter bores, and provided with the body and assembly device, the cord grip can accommodate a wide range of cord diameters.

Granted: 2006-03-21
Abstract: An acoustic logging tool having an acoustic transmitter and at least one acoustic receiver longitudinally spaced from the transmitter is lowered into a borehole fluid within a tubular member having a known resonant frequency. A pulse of acoustic energy is then transmitted into the tubular member, and acoustic energy traversing the tubular member and formation is detected at the acoustic receiver. A frequency domain transformation is performed on the detected acoustic energy and a cement bond evaluation is performed by comparing transformed detected acoustic energy amplitudes within a predetermined range of the resonant frequency of the tubular member, effectively filtering out acoustic energy which traverses the formation surrounding the tubular member.

Abstract: An off-road vehicle has an undercarriage and a superstructure and a tilting mechanism for levelling the superstructure. The tilting mechanism comprises upper and lower members coupled to tilt about a tilt axis by a hinge. The lower member is pivotally mounted to the undercarriage. A brake allows the orientation of the tilt axis relative to the undercarriage to be locked. The tilt mechanism allows the superstructure to be levelled by a method which includes the steps of releasing the brake, rotating the lower member until the tilt axis is horizontal, and tilting the upper member about the tilt axis until the superstructure is level. The tilting mechanism is simple and provides a full range of tilt in all directions. A tilting mechanism may be retrofitted to existing vehicles.

Title: Use of taurolidine for treatment of leukemias
Inventor: MORRISSEY JAMES H
IPC: A61P35/02

Granted: 2007-10-02
Abstract: Taurolidine (taurolin; tauroline; 4,4'-methylenebis(perhydro-1,2,4-thiadiazi n 1,1-dioxide) has been found to be an effective agent for treating patients inflicted with monocytic and/or myeloid leukemias through the induction of apoptosis in leukemia cells. Concentrations of taurolidine in the range of 50 to 100 .mu.g/ml induced apoptosis in 75 % of peripheral blood monocytes incubated in culture medium within six hours. Further, 100 .mu.g/ml taurolidine induced apoptosis in 92 % of granulocytes incubated in culture medium within six hours. Taurolidine was also effective in reducing the hypercoagulable state associated with tissue factor expression on leukemia cells, providing a means by which the incidence and degree of severity of coagulopathies associated with tissue factor expression can be reduced in leukemia patients. Preferred therapeutic dosages for treatment of leukemias are from about 10 to about 500 mg/kg body weight. Most preferred is a dose that results in a 200 .mu.g/ml concentration in the plasma, which is typically about 150 mg/kg body weight.
