Abstract: A perforating apparatus (100) includes a plurality of shaped charges (102) each having a case, an initiation end and a discharge end. A detonating cord (116) is operably associated with the initiation ends of the shaped charges (102). An energy absorbing charge holder (104) has a gas expansion region and a detonating cord receiving area to receive the detonating cord therein (116). The energy absorbing charge holder (104) also has a plurality of charge receiving locations that closely receive the shaped charges (102) therein such that upon detonation of the shaped charges (102), energy is transferred from the cases of the shaped charges (102) to the energy absorbing charge holder (104), thereby reducing fragmentation of the cases.

Abstract: The silo includes at least three hoppers, each formed by flat inclined plates along opposite sides and ends terminating in rectilinear discharge openings extending lengthwise transversely of a loading area for trucks below the discharge openings. Clam gates are movable between open and closed positions to discharge material into the truck bed. By using flat sided hoppers, the discharge area at the bottom of the silo is increased, facilitating faster loading of trucks with the particulate material.

Abstract: A perforating apparatus (100) includes a plurality of shaped charges (102) each having an initiation end and a discharge end. A detonating cord (116) is operably coupled to the initiation ends of the shaped charges (102). A carrier (106) contains the shaped charges (102). The carrier (106) includes at least one discharge location corresponding to the discharge ends of the shaped charges (102) when the perforating apparatus (100) is in its operable position. The discharge location has first and second material layers (122, 124) wherein the second material layer (124) exhibits resilient recovery such that an opening created by a jet formed from detonating one of the shaped charges (102) in the second material layer (124) is smaller than an opening created by the jet in the first material layer (122), thereby retaining debris in the perforating apparatus (100) with the second material layer (124).

Abstract: A detonator system for borehole systems which include detonating cord exposed to borehole fluids, pressures and temperatures. A firing head has a sealed chamber for an electrically fired detonator and has a booster charge holder forming part of the seal. The chamber is sealed by a wire line firing sub and by the booster holder. The charge holder includes a bulkhead separating the detonator chamber from a booster charge chamber and providing part of the detonator chamber seal. The detonator explosive and the booster charge are positioned on opposite sides of the bulkhead so that upon detonation of the detonator, the bulkhead is ruptured and the explosion transfers to the booster charge and from it to the detonating cord. The firing head includes holes for attachment of borehole tools such as perforating guns or back off tools to be fired by the detonating cord.

Abstract: A unique phasing pattern is provided that maximizes the effective perforation geometry of a wellbore. The improvement overcomes the problems associated with multi-phase guns of the past that failed to account for the fact that the gun rested on the low side of the casing. In one embodiment of the present invention, the phasing is arranged so that there is a zero phase tunnel formed. The zero phase tunnel is located at approximately the location where the gun rests against the low side of the well. Further, tunnels are formed by shape charges at plus and minus forty-five degrees and at plus and minus ninety degrees. This can also be referred to as a penta-phase. In another embodiment of the invention, charges can also be placed to allow for a plus and minus one hundred and thirty-five degrees pattern in addition to the penta-phase pattern described above. This expanded pattern can also be referred to as a hepta-phase pattern.

Abstract: A portable dispenser for dispensing a variety of tape materials which includes a base portion formed as a C-shaped or continuous clamp which is engageable over the back of an individual's hand so as to not interfere with the normal use of the fingers and thumb and which supports a tape supply housing and a cutter assembly which are spaced relative to one another so that a length of tape may be extended from the tape supply housing with the free end thereof positioned adjacent a cutting edge.

Abstract: Detachable trays for water beds having wooden side rails and headboards wherein the trays include one or more shelves or support surfaces which are vertically oriented with respect to one another and wherein the lowermost shelf or support surface includes an enlarged surface portion and a reduced surface portion which cooperate with mounting legs extending from the enlarged surface portion so as to enable the trays to be slideably engaged along the full length of the bed side rails with portions of the lowermost shelf being extendable beyond the headboard when the trays are positioned in close proximity to the headboard.

Abstract: In preparing arylalkanoic acids, e.g. ibuprofen or naproxen, via the conversion of the selected .alpha.-haloketal derivative of a 1-haloethyl aryl ketone to the haloalkyl ester of the arylalkanoic acid using a zinc salt catalyst the improvement comprising reacting a ring-substituted 6-membered ring ketal of the selected 1-haloethyl C.sub.6 -C.sub.12 -aryl ketone with a soluble zinc carboxylate salt to form the corresponding 3-haloalkyl arylalkanoic acid ester. The ester is converted to the alkali metal salt of the acid with base in an aqueous/water insoluble organic liquid mixture and the crude salt is converted to the corresponding acid in an aqueous/water insoluble solvent mixture for the acid, the organic solution of the acid is washed with a pH 7.0 to 8.

Abstract: The process of the present invention transforms 17-keto steroids (I) to the corresponding corticoids (IV) in three steps.

Abstract: A system and method for maintaining a prescribed track pitch in an optical storage system wherein a second radiation beam is aligned a desired distance from a first radiation beam, the first radiation beam being controllably steered to follow a previously written data track on a record carrier used within the optical storage system. A write alignment servo aligns the second radiation beam the prescribed distance from the first radiation beam in response to an offset signal. The offset signal is generated by optically measuring the distance between a pair of calibration tracks that have previously been placed on the disk so as to have the desired track pitch therebetween. The effect of variations or drift occurring in the optical or electrical components of either the write alignment servo or the optical track pitch measurement system is significantly reduced by regularly calibrating against the fixed track pitch of the calibration tracks.
