Patent CA-1113919-A (CA)
Inventor: WALTER BRUNO
IPC: F03C2/30

Granted: 1981-12-08
Abstract: ABSTRACT OF THE DISCLOSURE           A down-hole hydraulic or mud motor of the type adapted to be connected to the lower end of a drill string and powered by drilling mud for driving a drill bit is described.          The down-hole motor is capable of operating at a much slower speed than conventional motors thus enabling the use of conventional drill bits.  The motor includes a Venturi system which creates a suction effect on the exhaust fluid thus increasing the effective fluid pressure drop across the working chambers of the motor.  The motor also includes improved valving means and is also arranged to prevent large particules of grit and the like from entering the working chambers of the motor.          The motor may also include a unique form of pressure balanced flap arrangement which serves to reduce flap to stator contact pressures thus providing for longer flap wear.  Furthermore, to reduce the amount of vibration and shock forces reaching the bearings which support the rotor within the stator, a unique form of shock-absorbing arrangement is provided.  An overrunning clutch may also be provided to prevent reverse rotation of the rotor relative to the stator.  This serves to protect the flaps and also permits the drill bit to be rotated from the surface in the event of motor failure.  A unique form of locking system is also provided for locking the rotor relative to the stator in the event of an emergency situation occurring.  In order to activate the locking system, a heavy object can be dropped downwardly through the drill string thus striking certain components and activating the lock.  The motor is also designed so that it can be disassembled for maintenance purposes and re-assembled with a minimum of effort.

Abstract: ABSTRACT OF THE DISCLOSURE           A process and apparatus for transfer printing of a wide substrate from patterned webs or sheets of lesser width, in which the webs are fed side-by-side parallel to one another, any staggering of the pattern being corrected by suitable adjustment of web tensioning rollers by detecting reference marks corres-ponding to the pattern.  The webs can then be joined by sticking, or are directly used for transfer printing without being secured together, by being fed into transfer rollers together with a substrate onto which the pattern is to be transferred.

Abstract: 47,901 IMPROVED STRUCTURAL SUPPORTING ARRANGEMENTS FOR      A MULTI-BREAK LIVE-TANK CIRCUIT-BREAKER ASSEMBLAGE HAVING IMPROVED VOLTAGE-DISTRIBUTION CHARACTERISTICS BETWEEN THE SEVERAL SERIES BREAKS                 ABSTRACT OF THE DISCLOSURE         A multi-break, high-power, live-tank, circuit-interrupter assembly has improved inherent voltage-divi-sion characteristics by having upstanding supporting column structures disposed slantingly outward, in a diverging "V"-shaped relationship, or, alternatively, vertically-disposed in an inverted "U"-shaped relationship.  A modi-fied mounting constitutes a generally inverted "U"-shaped supporting construction, with the series multi-breaks disposed at the upper horizontal side of the structure, that is disposed within the horiziontal "bight" portion of the inverted "U"-shaped supporting structure.  This minimizes the effects of inherent parasitic capacitance, which tends to lead to unequal voltage distribution between the several series breaks.

Abstract: ABSTRACT OF THE DISCLOSURE          A unique, current conducting bipolar separator in a cell for electrolysis of chlorides makes multiple contact with the anodes and cathodes bonded to an ion transporting membrane in an electrolysis cell.  Each side of the separator plate includes a plurality of electrode contacting, current conducting ribs or projections which also define a plurality of flow channels to allow fluid transport and good flow distribution. The projections or ribs on opposite sides of the separator plates are angularly disposed relative to each other so that the membrane is supported on one side by ribs of one separator and on the other side by the ribs from another separator which are angularly disposed to the first group.  The intersection of the ribs on opposite sides of the membrane, thus, establishes a plurality of pressure areas or bearing surfaces which support the membrane without deforming it and without requiring very precise registration and alignment of the ribs.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for producing petroleum from subterra-nean formations is disclosed wherein production from the formation is obtained by driving a fluid from an injection well to a production well.  The process involved injecting via the injection well into the formation an aqueous solution of lignosulfonate salt modified by alkoxylation as a sacri-ficial agent to inhibit the deposition of surfactant and/or polymer on the reservoir matrix.  The process may best be carried out by injecting the lignosulfonates modified by alkoxylation into the formation through the injection well mixed with either a polymer, a surfactant solution and/or a micellar dispersion.  This mixture would then be followed by a drive fluid such as water to push the chemicals to the production well.

Abstract: ABSTRACT OF DISCLOSURE An apparatus and method for detecting and locating a fluid leak in an underground pipe or the like in which the vibration produced by the leak is intercepted at selected spaced apart points by microphones or other trans-ducers, in which the vibration intercepted at each of the two points is con-verted into an electrical signal, and in which the extent of correlation of the two resulting signals is varied by variably time delaying one signal re-lative to the other to determine the leak's location from the occurrence of maximum correlation between the signals.  In one embodiment, the variable time delay of one signal relative to the other is accomplished by a variable length time delay line and a means for progressively varying the length of the delay line.  In another embodiment the variable time delay is accomplished by a re-circulating delay line analyzer that does more data age comparisons with the same delays in the same time than the variable length delay line.
