Abstract: An improved construction for articles of footwear, such as boots and shoes of all types, includes an inflated insert, preferably in the shape of an insole, having a multiplicity of intercommunicating, gas containing chambers, and a ventilated moderator member which overlies the inflated insole for evenly distributing the forces exerted by the gas containing chambers across the plantar surface of the foot of the wearer. The material from which the insole is constructed and the gas contained in the intercommunicating chambers of the insole member are selected so that the rate of diffusion of the gas through the barrier material of the insole will be extremely slow, the insole remaining inflated to a substantial pressure for several years.
Abstract: An underwater template has one or a plurality of pile housings through which piles are driven into the earth at the floor of the water to fix the template in place by forging the pile into grooves in the housing. The forging operations are performed by a rotary cold forge tool with expansible rollers, the tool being rotatable by a running string of drill pipe guided by a swivel which lands on and is centered by the pile, or the forging is done by explosives confined between seals within the pile section.
Abstract: A well packer has a casing engaging slip mechanism and a packing element carried on a tubular body which is released from the slip assembly enabling setting of the slips and packing by an upward pull on a running in string of pipe. The body and the expander for the slips are locked to hold the packer set. A length of tubing extends through a seal in the body and is released to be slideable in the body enabling temperatue change responsive elongation and contraction of the running pipe, without affecting the packer. A shearable release enables retrieval of the packer assembly by pulling on the running pipe. An emergency release of the running pipe is accomplished by releasing a guide on the end of the slideable tubing.Well bore packers are frequently used in well casings, with a tubular string of running and retrieving pipe or tubing associated with the packer and held in tension. In the presence of high temperatures, the resultant expansion of the tubing tends to relieve the tubing tension.
Abstract: A helicoidal in-hole motor assembly has a speed change gear drive for converting the eccentric motion of the rotor to concentric rotation of the drive shaft at a different speed. The gear set is enclosed in a sealed housing containing gear lubricant. An eccentric yoke and bearing enable orbital motion of the drive gear.
Abstract: A ring gasket is retained in position on a pipe connector flange with the ring gasket properly positioned for sealing engagement and loading between opposed circular grooves in the flange and a mating flange or member. The ring gasket is supported on one of the connector parts by a spacer ring or by a portion of the flange which effects a standoff between the connector parts when they are connected. In the case of a separate spacer ring, it is connected to the flange or supported adjacent to the groove by a support member adapted to be hand-held. The support for the ring gasket includes elements frictionally engaging or biting into the outer periphery of the ring gasket. The ring gasket has outer peripheral, oppositely tapered sealing surfaces loaded into sealing engagement with opposing companion surfaces forming the grooves in the flanges upon making up of the connection.

Abstract: A connecting rod assembly has universal joints at the ends of a connecting rod of tubular construction, the universal joints being lubricated by grease contained in the tubular rod and retained in the universal joints by flexible boots disposed about the exterior of the universal joints, the tubular rod containing a pair of pistons between which fluid from exterior of the universal joints can enter the tubular rod and equalize the pressure in the universal joints with the external fluid pressure.The connecting rod assembly is installed between the rotor of an in-hole fluid motor of the progressive cavity type and the drive shaft of a bearing assembly for a motor driven drill.
Abstract: A retrievable double grip well packer having an elongated tubular body, longitudinally spaced, upwardly holding and downwardly holding expander and slip mechanisms and an intermediate, elastomeric deformable packing which are sequentially expanded into anchoring and sealing engagement with the well casing upon relative longitudinal movement between the body and the upwardly holding and downwardly holding slip and cone mechanisms. The body is locked in position holding the packer set and anchored. The downwardly holding slip and cone mechanism is connected to the body by a releasable connection and the elastomeric packing is supported by a telescopic sleeve which enables the slip and cone mechanism to be easily released from the casing. The body and the upwardly holding slip and cone mechanism are constructed to enable the packer to be run on pipe and mechanically actuated by shifting the body relative to casing engaging friction means which effects expansion of the slip and cone mechanisms and the packing.
Abstract: A spring actuated pump device is mounted on a container for fluid, the device including a pump chamber into which fluid from the container can flow, the spring forcing a cylinder structure against the fluid in the chamber to pressurize it, in order that opening of a finger actuated discharge valve will effect spraying of a desired quantity of fluid from the device, a suitable captive nut being swivelly mounted on the container against axial movement with respect thereto, the nut being threadedly connected to the cylinder structure to enable such structure to be shifted axially in response to rotation of the nut relative to the container and cylinder structure to compress the spring and store additional fluid pressurizing energy therein.
Abstract: A subsea template is installed on a level base provided by lowering and landing on the floor of the sea a container to which is supplied a quantity of fluent, settable material which flows to form a level upper surface on which the template is landed. The template is fixed in place by setting a pile into the floor of the sea. The receptacle is a guide base anchoring guidelines on which the template is lowered after hardening of the fluent material, or, in the case of a guidelineless installation, the base and template are lowered together and the template raised above the base during setting of the fluent material and then lowered onto the level base.
Abstract: A misalignment connector for large pipelines, conductor pipes or the like, includes an internal, metal seal ring having an external spherical periphery which is axially and circumferentially loaded between opposed internal spherical surfaces of connector structures which are operable by hydraulic piston and cylinder means to be interconnected over a range of angular misalignment. The internal sealing ring is preloaded when the connector parts are secured together. Initially, the internal sealing ring is supported in or nearly in engagement with one of the companion spherical surfaces of the connector parts for proper engagement and angular motion upon the interconnection of the connector parts over the permissible angular range of misalignment. The connector is made up by the application of fluid pressure to the actuator cylinder and piston means after the connector parts have been stabbed together. Radially shiftable locking elements are wedged towards one another by the action of the actuator cylinders.
Abstract: A packer having an orienting device is lowered in a well bore to a desired location and turned, if necessary, to point the orienting device in a selected direction, after which the packer is anchored against movement in the well bore. A whipstock, anchor and orienting mandrel are secured together in such manner that an orienting device on the mandrel, companion to the packer orienting device, is aligned with the whipstock. The whipstock, anchor and mandrel combination is then lowered in the well bore, the mandrel orienting device engaging the packer orienting device, effecting turning of the combination to point the whipstock in the same final direction as the packer orienting device, whereupon the anchor is secured to the packer to prevent movement of the whipstock from its final oriented position, which is the direction that a suitable cutting tool is to be deflected by the whipstock to cut a window in a well casing in the well bore, to sidetrack the well bore, or to perform both of these operations.
Abstract: A misalignment connector has a pair of hubs providing internal, opposed spherical surfaces loaded into engagement with an internal, metal sealing ring having a spherical, outer sealing surface, the hubs being constrained together to maintain loading of the seal ring over a range of angles of misalignment. The internal seal ring is initially retained in position with respect to one of the hubs and is shiftable for proper sealing and loading engagement by the hubs over the range of permissible misalignment. The metal-to-metal seal between the hubs and the seal ring is backed up by a resilient seal. The metal seal ring has an outer peripheral projection forming a connection for the retainer, and the projection is engageable by the hubs to angularly shift the seal ring during assembly.
Abstract: A pipe connector has a pin initially stabbed into a box, the pin and box then being axially loaded together at confronting transverse surfaces while the pin and box are pressurized to expand the box and compress the pin, so that when the pressure is relieved a pressure energized shrink fit is provided and the connector is rendered rigid to enhance tensile, compressive and bending strength and provide a fluid tight joint useful in making up lengths of pipe such as piles and pipelines. Locking means are installed while the connector is pressurized, is axially loaded by a loading tool and before pressure is relieved, the locking means engaging between opposed pin and box shoulders to retain the pin in compression and the box in tension when the pressure is relieved and the loading tool removed. The locking means is a wire, discs, balls or a split ring.
Abstract: A hole-opener and a hole-opener apparatus is provided for enlarging a pilot hole of the inverted arcuate type which bypasses an obstacle, the pilot hole having an entrance and terminal end, both ends usually being accessible to surface drilling equipment.
Abstract: An equalizing valve is incorporated in a subsurface shutoff valve for wells and has a number of balls loosely confined in an annular groove in the tubular valve body and adapted to seat in by-pass ports in the shutoff valve actuator piston sleeve to prevent flow through such by-pass ports from ports in valve body which communicate with the groove. Actuation of the piston sleeve to open the shutoff valve causes a shoulder forming the groove to wipe the seated balls from the by-pass ports to equalize fluid across the shutoff valve before it is opened. The shutoff valve is of the ball type or of another type. The shutoff valve of the ball type, when closed, subjects its support bars to a force deforming them to allow the shutoff valve ball to move into seating engagement with a seating sleeve to prevent extrusion of an elastmer seal.
Abstract: This invention relates to production of improved zeolitic catalysts produced from mixtures of cation exchanged zeolites of the faujasite type incorporated into a matrix such as alumina, silica-alumina gels and clay or mixtures thereof.
Abstract: A hanger for supporting dual tubing strings in a well casing from hanger mandrels which can swivel to facilitate threadedly connecting each mandrel to its associated tubing string. The hanger includes an orienting sleeve for receiving safety shut-off valves, the sleeve being adapted to swivel with respect to the rest of the hanger, making it easier to assemble the hanger onto the running and setting tool used for setting the hanger in the casing. The running and setting tool is releasably secured to the hanger. By imposing fluid pressure on the setting tool, the tubing hanger slips are expanded against the casing.
