摘要： A hydraulic intensifier for oil well fracturing and/or erosion drilling, having a pair of intensifier units including a pair of sequentially operated reciprocating ram assemblies powered by hydraulic cylinder motors which are operated to maintain a substantially uniform output fluid pressure from the intensifier unit. Each cylinder motor is supplied from a main source of hydraulic fluid under high pressure which operates on the working faces of the pistons of the cylinder motors. Hydraulic fluid is also supplied to the return face side of each piston in the hydraulic cylinder motor. The return face side of the pistons have a smaller operative area than the working face sides and each can be connected to the main source of supply of hydraulic fluid to the working faces so that as the pistons are driven to their extended positions by application of hydraulic pressure to the working face, the fluid on the return face side can be expelled from the cylinder motors and returned to the working face side to either reduce the fluid flow from the source while maintaining the same cycling rate or maintaining the same flow from the source by increasing the cycling rate and thus increasing the total volume flow. An adjustable pressure relief valve is provided to permit control of the pressure in the well to a maximum desired limit by relieving pressure of the infeed fluid to the hydraulic cylinder motors.

摘要： A hydraulic intensifier for oil well fracturing and/or erosion drilling incorporates a pair of intensifier units mounted on a common bed. The intensifier units are particularly defined for ease of maintenance in the field, and structure is provided by which the ram seals as well as the ram, the ram cylinder, and the hydraulic cylinder can be easily and readily removed in the field without the necessity for releasing the tension on the tie rods. To this end, the apparatus includes a front wall which supports the ram cylinder and an intermediate wall which supports the forward end of the hydraulic cylinder. The space between these walls and the manner in which the components are assembled permits the ram seal assembly, the ram and ram cylinder, and hydraulic piston to be extracted and reinserted. Also, an improved ram return system and a hydraulic cushioning system are disclosed.

摘要： A quadraplex pumping unit for use as a mud pump, an intensifier, or as a pump for abrasive fluids or the like includes four rams and four ram operating pistons. A control valve arrangement provides for pressure equalization and energy transfer from a cylinder which has just extended in a working stroke to a companion cylinder which has just returned to its retracted to rest position, to conserve energy and reduce the thermal burden on the hydraulic system. The valve arrangement further provides for prepressurization, after pressure equalization, prior to an extending stroke.

摘要： An intensifier unit includes a pair of sequentially operated reciprocating ram assemblies, each powered by a cylinder motor. Extension of the cylinder rods is accomplished by application of pressurized hydraulic fluid to the pistons. The pistons are returned quicker than they are extended by means of continuous application of pressurized air to the back side of the pistons. The cylinder motors are precompressed prior to their respective forward strokes by means of an accumulator which continuously bleeds from the main hydraulic fluid supply line. Circuitry is provided to insure that precompression continues even if the ram and its driving piston move from their retracted position. Also disclosed is a safety interlock to shut down the intensifier if both cylinder rods become accidentally simultaneously extended.

摘要： A bale debanding method and apparatus comprising a band breaking blade, a band winding mandrel and a mandrel cleaning plate are mounted to a frame. A support table is attached to the frame for receiving a waste paper bale that is held together by banding material. As the bale is moved past the band breaking blade, a band retention notch engages a band and by stretching it breaks the band. Once a band is broken, an extensible band catch extending out of the mandrel contacts the band and facilitates the band in being wound around the mandrel. Once all of the bands have been removed from the bale, the band catch is retracted to a position within the mandrel and a cleaning plate is moved axially along the mandrel sweeping the bands off a free end of the mandrel. This process is repeated to remove bands from other surfaces of the bale, thereby releasing the waste paper in preparation of processing.

摘要： A rheometer has temperature control means which include a bath through which liquid is circulated, so that it will completely immerse both the upper and lower probes or plates between which a sample, whose rheological are being investigated, is located. This allows the temperature of the sample to be closely controlled to within 0.2.degree. C. of a selected temperature. The rheometer is particularly suitable for measuring the properties of bitumous materials which are extremely temperature sensitive.
