Abstract: A beta radiation sensor and an X-ray radiation sensor are used to monitor the specific weights of both components of a two-component web, in particular, a web of magnetic recording material, by using the beta radiation sensor to measure the combined specific weight of the material. The measurement by the X-ray sensor permits such combined specific weight to be apportioned between the two components of the web. Cross talk between the two sensors arising from bremstrahlung produced by the beta radiation sensor is suppressed by softening the beta radiation beam with films of polyester, by shielding the housing in which the detectors of the two sensors are disposed with a sheet of phenolic, and by stopping down the aperture through the sheet of phenolic through which X-ray radiation enters the detector housing.

Abstract: The water permeability of a subterranean formation is selectively reduced by introducing a non-aqueous treatment agent into the formation. The treatment agent comprises a hydrogel polymer and a non-aqueous fluid carrier. The treatment agent preferably further comprises an alkali metal carbonate when calcium-rich aqueous brines are resident in the formation. The treatment agent is maintained within the formation for a time sufficient to permit the hydrogel polymer to absorb water from the formation. As it contacts water, the hydrogel polymer swells and thereby blocks further water flow through formation pores. Treatment of formations in accordance with this method permits enhanced recovery of minerals, such as hydrocarbons, by selective reduction of water flow into producing wells or shafts.

Abstract: A system for aborting the dual pathway tachycardias in a heart comprising the syndrome of paroxysmal supraventricular tachycardia (due generally to atrioventricular nodal reentry or atrioventricular reentry using an anomalous atrioventricular connection for retrograde conduction) by sensing cardiac impulses and, with respect to each sensed cardiac impulse, determining if such sensed cardiac impulse is an inciting cardiac impulse, a cardiac impulse which occurs at a time with respect to the last received cardiac impulse which falls within a predetermined echo zone and which will result in the initiation of a dual pathway tachycardia, and inducing an aborting cardiac impulse in response to a sensed inciting cardiac impulse in the cardiac muscle at a time within the predetermined aborting zone for aborting the initiation of the dual pathway tachycardia.

Abstract: The present invention contemplates electronic ammunition for simulating live ammunition detonation when utilized with an ammunition firing device having a mechanism for firing ammunition when triggered wherein an electronic sound assembly is disposed within a component space within a shell and the shell is loaded within the ammunition firing device. The electronic sound assembly has recorded therein the sound of the detonation of live ammunition and is adapted for providing the live ammunition sound in an audibly perceivable form in a play mode in response to receiving a triggered signal.

Abstract: An improved rotating head having an inner barrel disposed within and rotatingly supported on an outer barrel wherein an elastomeric member is connected to the inner barrel via bolts and a kelly is extendable through the inner barrel and through the elastomeric member, the elastomeric member sealingly engaging the kelly, and wherein a lid is connected to the elastomeric member encompassing the bolts connecting the elastomeric member to the inner barrel for retaining said bolts in the event any of said bolts become inadvertently unthreaded.

Abstract: Subterranean paths of water flow are impeded or changed by the facilitation of microbial growth therein. Either indigenous bacterial growth may be stimulated with nutrients or the formation may be first seeded with bacteria or their spores which inhibit fluid flow after proliferation. These methods and bacteria are usable to alter the flow of water in a waterflooded oil formation and to impede the outflow of contaminated water.

Abstract: A tool for aligning pipes to be secured in an end-to-end relationship which includes a strap to be secured around the end of one pipe and a lever engaging the strap, the lever having a foot to engage and deform a portion of the other pipe.

Abstract: A battery box hold-down comprising three metal strips. One metal strip is attached by one end to a base and has a slip-joint hinge component at the second end. Another metal strip is attached by one end to a base and has a hasp component at the second end. The top metal strip, shaped to fit over the top of the battery box, has a slip-joint hinge component at one end and a hasp component at another end. When the top metal strip engages over the battery box, the attached metal strips by slip-joint and hasp and a lock is fixed through the hasp, the battery box is fixed in a secure position.The battery may be serviced by unlocking the lock and disengaging and removing the top metal strip and the battery box top.

Abstract: A filtration module formed from a first flexible sheet having a first edge section, an opposed second edge section and an interior section, comprising engaging each portion of the first and second edge sections respectively to uncorrugated first upper and lower terminal elements. Corrugations are formed in the first upper and lower terminal elements of the first flexible sheet-terminal elements assembly, and slits are cut in the interior section of the first flexible sheet-terminal elements assembly, with the slits extending transversely to the edge sections. Each adjacent pair of slits in the interior section defines a ribbon element. One or more filtration modules may be assembled to form a filter by stacking the elements or by winding the filtration module or modules around a central core. The stacked or wound filtration modules are supported within a housing so that each ribbon element is disposed in a fully extended, fexible state.

Abstract: A sorting gate assembly adapted for use in cooperation with a holding pen including a sorting gate and a gate support assembly. The sorting gate is movably connected to the gate support assembly for movement in a first direction generally toward the gate support assembly and for movement in a second direction generally away from the gate support assembly. The gate support assembly also movably supports the sorting gate for movement of the sorting gate in a first direction generally away from the exit of the holding pen and for movement in a second direction generally toward the exit of the holding pen. The sorting gate is movably supported on the gate support assembly for movement within the holding pen to sort a selected animal and to move the sorted animal into an exit area portion of the holding pen for exiting the animal through the exit of the holding frame.

Abstract: A fishing tool comprising a body member having an offset entrance port into a cylindrical cavity that contains a slide member having a trough-shaped lower portion positionable adjacent the entrance port in either of two diametrically opposed angular positions to alternatively capture or release an enlargement on a rod inserted into the body member cavity via the entrance port. Grooves are cut into the slide member and a pin is mounted on the body member to rotate the slide member one half turn when the slide member is reciprocated in the cavity. The rod can be a portion of a collet in a barrel attached to the body member, the bore of the barrel and the collet having mating frustoconical surfaces for collapsing the collet fingers about a uniform diameter rod when the rod portion of the collet is released from the body member and slide member.

Abstract: Pulses produced by a pulse generator coupled to the output shaft of an electric motor that reciprocates a polish rod of a well pumping system are counted by a computer to locate the polish rod at a series of positions during each reciprocation of the polish rod and the dynamic load on the polish rod at each of these positions is determined by the computer from the time difference between pulses. The pulse count and dynamic loads are simultaneously displayed on a two-dimensional array of light emitting diodes under the control of the computer to visually present the dynamic pumping characteristics of the system. The operation of the system following pump off or breakage of a sucker rod is interrupted by controlling the operation of the motor via the computer, the computer switching off the motor following the occurrence of a preselected set of dynamic loads for a preselected set of pulses.
