  • Publication number: 20060016599
    Abstract: A method of initiating fluid circulation in a well bore through a casing inner diameter and an annulus outside the casing, the method having the following steps: inducing an increase in the annulus fluid pressure; flowing cement composition into the annulus at the top of the well bore; maintaining a difference in pressure between the fluid pressure of the casing inner diameter and the fluid pressure of the annulus until enough cement composition has entered the annulus to drive fluid circulation by the added cement composition weight.

  • Publication number: 20020108160
    Abstract: A wetsuit structure (10) having a zipper (15) extending from a neck opening (14) of the wetsuit and down that portion of the wetsuit which, in use, will at least surround the upper part of the torso (11) of a wearer of the wetsuit. A barrier panel (16) of stretchable, substantially water proof, material is attached within the interior of the wetsuit adjacent to, and underlying, at least a major portion of the length of the zipper. The wetsuit structure also has a detachable neck or collar (17) of stretchable, substantially water proof, material adapted, in use, to be pulled over the head of the wearer while stretching in the process, but then relaxing to fit relatively tightly into sealing engagement around the neck of the wearer, and a series of press studs or snaps (18, 19) to detachably connect the neck or collar to the body of the wetsuit.

  • Publication number: 20010052176
    Abstract: A tool for withdrawing a shifter shaft from a transmission comprising a a smaller cylinder mounted concentrically on a largest cylinder. A concentric bore extending through the tool is dimensioned for a slip fit onto the shifter shaft. An open slot extending from end to end of said tool permits straddling the tool onto the shifter shaft. The smallest cylinder is then engaged with the a hole in the end of the shift lock wherein a flat surface on the outside surface of the smallest cylinder abuts flat section of inside surface of the shift lock. The tool is then used to rotate the shift lock so as to align one or more pins in the interior surface of the lock housing with internal grooves in the shift lock so as to permit separation of the shift lock and shifter shaft from the lock housing.

  • Patent number: 6307693
    Abstract: A magnetic media storage system output circuit includes a filter for filtering an analog output signal from the storage media system before the analog output signal is provided to a read channel. Within the magnetic media storage system a read/write head reads data from a magnetic medium and provides an analog signal representing the data to an output circuit. The output circuit includes the filter for filtering the analog output signal and a pre-amplifier circuit for amplifying and transmitting the analog output signal to a read channel. Preferably, the filter has a linear frequency response and constant group delay below the cutoff frequency. Current on a write current control pin is used to control the cutoff frequency of the filter so that the cutoff frequency will track the data rate. An output signal from the storage media system output circuit is provided to a read channel.

  • Patent number: 5879060
    Abstract: Multiposition valves are used for instance to interrupt a flow of pressure fluid that begins at a pressure source, such as a master cylinder, and leads to a consumer, such as a wheel brake. To that end, such multiposition valves have a valve seat, a valve seat closing body, an electromagnet which presses the valve closing body against the valve seat, and a valve opening spring, so that when the electromagnet is turned off, the valve closing body assumes an outset position spaced apart from the valve seat. To reduce noise production, especially when power is supplied in pulsed fashion to the electromagnet a further spring is provided that urges the armature in the direction of its outset position, so that when the valve opens, the armature can lead ahead of the valve closing body. The valve is advantageously usable in a hydraulic vehicle brake system where irritating noise production during operation is to be avoided.

  • Patent number: 4937037
    Abstract: An electronic recording and display apparatus for performing the function of a chart recorder comprises a solid state display device controlled from a memory by a display controller. The memory receives signals in the form of 8-bit binary number digitized by a signal digitizer from an analogue input signal. the display device graphically displays a set of the signals stored in the memory and this can be "scrolled" through all the information stored in the memory in a manner similar to a chart recorder.

  • Patent number: 4090119
    Abstract: Apparatus for electronically simulating the response of a direct current traction motor to predetermined operating states whereby there is provided a resultant signal representative of the torque that would be produced by an actual motor operating in the prescribed states. The apparatus calculates E per RPM for the simulated motor from measured values of available armature voltage and armature velocity. A function generator thereafter converts the E per RPM signal to a signal representative of the motor field current based upon known values for the simulated motor. The field current signal is converted to an armature current signal by a circuit which responds to the motor commanded state of field weakening to compute the instantaneous ratio of armature current to field current under the commanded conditions and thereafter multiplies the field current signal by that ratio to obtain a signal representative of armature current.
