Title: High pressure downhole progressive cavity drilling apparatus with lubricating flow restrictor
Inventor: IDE RUSSELL D
IPC: E21B4/02
Filed: 1990-12-20
Abstract: A progressive cavity drilling apparatus which includes a drill bit (26), a drill bit driving shaft (16) have a hollow bore (25) formed therein and a progressive cavity drive train (A) for driving the drilling shaft (16). A flow restrictor (42) is provided to cause fluid leaving the progressive cavity drive train to enter the interior of the hollow drilling shaft and then to be exited therefrom through nozzles formed in the drill bit. The flow restrictor includes a groove (44) to allow a small amount of fluid to flow in a path winding around the circumference of the flow restrictor (42) and into a bearing assembly (30) located below the flow restrictor (42). Because the flow path winds around the circumference of the flow restrictor, it is significantly longer than a straight longitudinal flow path. Consequently, the velocity of the high pressure fluid through the flow path is significantly reduced thus minimizing erosion and wear of the flow restrictor. The flow restrictor may also function as a radial support which can obviate the need for a separate radial bearing. The radial support may be provided between the helical grooves or in a separate portion of the flow restrictor. The flow restrictor can also have an inner diameter which is eccentrically moveable with respect to the outer diameter of the flow restrictor so as to accomodate shaft movement.

Title: Method and apparatus for forming a wad
Inventor: OATLEY JOHN A
IPC: D04H13/00
Filed: 1991-09-11
Abstract: A wad of particulate material is formed by entraining fibres in a stream of air that flows through an air-permeable carrier strip from top to bottom, the fibres being deposited on top of the strip. The area on the strip where the fibres are deposited is defined by an aperture in a forming screen located below, and in contact with, the strip. The air stream is a result of a suction applied below the screen. With an aperture, a uniform layer of fibre is deposited on the strip.      Instead, the screen may have a forming zone which has a region of high permeability and a region of intermediate permeability, more fibre being deposited on that area of the strip in alignment with the high permeability region than that area in alignment with the intermediate permeability region. The wad is then stabilized and bonded to the carrier and a liquid impervious backing layer is secured to the strip, sandwiching the wad therebetween. The wad or that portion of the strip and backing to which it is bonded are cut out from the rest of the strip and the backing to provide a pad.

Title: Method and apparatus for controlling the output voltage of an ac electrical system
Inventor: KONISHI HIROO
IPC: H02M7/48
Filed: 1992-06-11
Abstract: The present invention relates to an AC system having, for example, a voltage source, an inductance and a load has connected thereto an apparatus for controlling the phase and amplitude of the voltage of the system.  The instantaneous current and voltage in the AC electrical system are measured and power measurements derived therefrom.  The power measurements may be instantaneous real and imaginary power, instantaneous active and reactive power, or active and reactive power averaged over less than one cycle.  The power measurements are then used to derive phase related control values, on the basis of which control signals are generated to a converter.  The action of the converter in accordance with the control signals thus controls the amplitude and phase of the voltage.  By use of power measurements, it is not necessary to measure the phase of the voltage of the AC system.
