Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to downhole apparatus for causing sealing or mechanical engagement between two conduits. The apparatus includes telescopingly interfitted housing (32) and mandrel (16) members movable one relative to the other to actuate the seal and anchor systems for setting the packer. A locking mechanism for holding the packer in the set position includes a cylindrical lock ring (72) having axially spaced ratchet teeth, referred to in the art as wickers (70), on an outer circumferential surface engageable with cooperating internal axially spaced ratchet wickers (62) formed on the housing member. The lock ring (72) also includes axially spaced teeth (84) on an inner circumferential surface engageable with cooperating teeth (76) on a collapsible latch system engaged with the mandrel which may be collapsed radially inwardly to release the lock ring with respect to the mandrel to permit relative movement between the mandrel and the housing to release the packer elements from engagement with the casing. The collapsible latch system is held in position by a supportive sleeve (52) slidably disposed in a bore formed in the mandrel and held in its retaining position by shear pins (95).               The arrangement of the mandrel (16) and housing (32) and the latching and releasing mechanism is adapted for use in well tools of all types and may be set by fluid pressure applied to an expansible chamber, within the apparatus, by various wireline setting tools adapted to move the mandrel with respect to the housing, or mechanically, and can be retrieved simply by shiftingthe supporting sleeve to release the latch system and lifting the tool by the mandrel.

Abstract: Abstract A solid dose ballistic projectile formed almost entirely of a cohesive mixture of biologically active material, in the form of grindable solid particles having an average diameter between about 7 and 25 micrometers, and biologically inert binder.  These projectiles are capable of containing more active medicament than conven-tional ballistically implantable projectiles.  The projec-tiles, even those made of up to 95 percent medicament, are capable of withstanding the stresses imparted thereon when the projectile is propelled ballistically from a barrel and implanted in the flesh of a living animal.  The ability of these projectiles to withstand such stresses is due to the projectile composition, including the particle size of the medicament.  These projectiles are used to administer medication to animals such as cattle and free-ranging animals.

Abstract: AUTOMATIC TOOL CHANGER WITH INTERNAL TOOL STORAGE MAGAZINE             ABSTRACT OF THE DISCLOSURE      A vertical spindle numerically controlled machining center includes a stationary bed or base on which a work-piece holding table is slidably mounted for movement along a first axis.  A vertically extending upright or column, having a vertically reciprocal spindlehead slidably mounted thereon, is slidably mounted on the bed for movement along a second axis perpendicular to the first axis so that the spindlehead overlies a portion of the table.  Within the upright is a recess adjacent to the bed.  A tool storage magazine is located in the recess and is slidably mounted on the bed for movement through the recess along an axis parallel to the second axis.  During a tool change cycle, the toolholder then held in the spindle is returned to the tool storage magazine by first moving the spindlehead to the ready position and then moving the tool storage drum toward the spindlehead to engage the tool then held in the spindle.  To provide the spindle with a new tool, the spin-dlehead is first moved upwardly to clear the toolholder shank and then the tool storage drum is indexed to position a new tool directly beneath the spindle so that the spindle can engage the tool when the spindlehead is moved down-wardly to the ready position.

Abstract: ABSTRACT OF THE DISCLOSURE:         A process for isolating and recovering butene-1 of high purity at a high yield is provided.  The process comprises the steps of continuously passing a butane-butene fraction containing 0.1 to 15 wt% of isobutylene and 10 to 50 wt% of butene-1 through a first reactor packed with a strongly acidic cation exchange resin having an average particle size of from 0.2 to 10 mm at a temperature of from 30° to 100°C and at a space velocity of liquid of from 0.1 to 50 hr-1 under a pressure of from 1 to 50 atm., dividing the output mixture flowing out of said first reactor into two flows at a division ratio in flow rate of 1 ~ 15 : 1, recirculating the first flow having the flow rate of 1 ~ 15 into said first reactor packed with said cation exchange resin, passing the second flow having the flow rate of 1 through a second reactor packed with a strongly acidic cation exchange resin under the conditions similar to those of the first reactor, distillating the output flow from said second reactor to separate the same into a heavy hydrocarbon fraction containing oligomers of isobutylene and a light hydrocarbon fraction containing butane and butene, and rectifying said light hydrocarbon fraction to isolate butene-1 from other C4-hydrocarbons.

Abstract: TITLE Delay Detonator ABSTRACT OF THE DISCLOSURE Improved uniformity of timing, and particularly reduced sensitivity of timing to minor variations in delay charge size, are achieved in delay detonators by placing a loose load of a flame-sensitive ignition composition between a pressed delay charge and an ignition assembly, e.g., a percussion primer, a the actuation end of the detonator.  The loose ignition charge has a free surface and is adapted to be ignited in response to direct contact with flame emitted from the ignition of a charge in the ignition assembly. Preferably, the delay charge is pressed into a plastic carrier which, in a non-electric detonator, has an open end terminating between the walls of the detonator shell and a primer shell that closes the actuation end of the detonator and the ignition charge is loosely loaded into a metal capsule seated against the delay charge.

Abstract: ABSTRACT          This invention relates to hydrophobic mineral oil-based composi-tions and to the use of such compositions as filling compositions particularly for telecommunication cable splice cases.  It has been found that filling composition comprising a fluid mineral oil and a hydrophobic fumed silica has excellent water-exclusion properties.  Fumed silica can be rendered hydro-phobic by treating its surface, and has excellent properties for use as a hydrophobic filling compound, without having the disadvantages of petrolatum-based compositions generally available.  The use of a fumed silica thickener having a hydrophobic surface provides a filling composition having improved water-excluding properties and a very low water content compared to similar compositions containing untreated, hydrophilic fumed silica.  Resistance to oil separation can be further improved by the addition of a low molecular weight polymeric thickener which is soluble in the mineral oil:  depolymerized butyl rubber is preferred.
