Abstract: The dual chamber - child-resistant blister package (22) is provided. The blisters of the package include a storage chamber (34) and a discharge chamber (36). In addition, the blister includes restraint means (38) for preventing the medicament (24) from moving from the storage chamber (34) to the discharge chamber (36) until a predetermined force is applied to the blister package (22). The medicament (24) may not be dispensed directly from the storage chamber (34), since a nonrupturable layer (30) is located adjacent the storage chamber (34) of the blister (22). The nonrupturable layer (30) includes an opening (44), or a mechanism such as a score line for forming and opening through which the medicament (24) can pass adjacent the discharge chamber (36). A rupturable layer (32) is also provided to seal the medicament (24) within the blister (22). Typically, the rupturable layer (32) is located adjacent the nonrupturable layer (30) to seal the opening in the nonrupturable layer (30). The blister package (22) may also include indicia associated with the blisters to help insure compliance with complex therapeutic regimens. The blister package may also include fold lines to help reduce the overall size of the blister package; thereby making it easier to transport.

Title: Gelatin capsules containing a highly concentrated acetaminophen solution
Inventor: SHELLEY RICKEY S
IPC: A61K31/165
Filed: 1994-08-04
Granted: 1999-10-12
Abstract: A method is disclosed for increasing the solubility of acetaminophen alone or in combination with antihistamines, antitussives, decongestants, and expectorants to form a clear solution for encapsulation into a softgel. The acetaminophen is solubilized alone or in combination with the above ingredients by mixing with polyethylene glycol, propylene glycol, water, polyvinylpyrrolidone and potassium (or sodium) acetate. This invention increases the solubility of the acetaminophen obtain the same size softgel for a 325 mg dose as is presently available for a 250 mg dose softgel product. The disclosed solvent system is useful because it provides for a highly concentrated solution of acetaminophen capable of encapsulation in a small enough capsule to permit easy swallowing.

Title: Board drying process and device
Inventor: BAHNER FRIEDRICH
IPC: F26B15/12
Filed: 1994-07-27
Granted: 2001-10-30
Abstract: In order to dry boards, the boards are guided on racks through a drier and brought into contact with drying air in two stages. In a stage A with a higher drying power, the drying air is supplied at a higher temperature and with an at least average humidity, and in the other stage B, it is supplied at an average temperature and with a low humidity. The waste heat of the outgoing air from stage A is used for preheating the drying air. This process should reduce the consumption of primary energy. For that purpose, a process is known that consists in also using the outgoing air condensation heat. This has the inconvenient, however, of requiring substantially more secondary energy, as important air mass flows are required to transfer heat because of the low condensation temperature. Primary energy should be reduced by using condensation beat without substantially increasing secondary energy requirements.  According to the invention, the outgoing air from stage A is supplied to stage B through a heat exchanger arranged in the rack of the drier. The drying air of stage B is supplied in counter-current through the drier with a low humidity and temperature, so that the boards are dried in stage B both by condensation heat and by radiant heat. Thus only a reduced mass flow of drying air is required to transfer the condensation heat. The consumption of primary and secondary energy is low. This invention is suitable for drying boards, in particular boards for buildings, such as gypsum plaster boards and fibre boards.

Abstract: A system for feeding a cable into a pipeline or other conduit comprises a rotating turret and a local cable feeding mechanism for drawing the cable off of the turret reel and loading it thereon. A remote cable feeding mechanism for inserting the cable into or withdrawing it from the pipeline is attached to a launch saddle secured to the pipeline, and its feeding rate is synchronized with that of the local cable feeding mechanism. Where the cable acts as an umbilical cable carrying fluids and electrical power to a tool inside the pipeline, the fluid and power supplies may be located on the floor of the reel, connected to an operator station by an electrical cable which winds onto and off of the turret shaft and is kept taut by a spring-biased tensioning arm. A flexible fibreglass rod extends through the cable to prevent coiling or bunching up within the pipeline while permitting the cable to traverse bends and corners.

Abstract: In summary, the present invention is a multithreaded computer system having a memory that stores a plurality of objects and a plurality of procedures. Each object has a lock status of locked or unlocked, and includes a data pointer to a data structure. The system uses a global object locking procedure to service lock requests on objects that have never been locked as well as objects that have not recently been locked, and uses a local object-specific locking procedure to service lock requests on locked objects and objects that have been recently locked. The global object locking procedure has instructions for changing a specified unlocked object's lock status to locked, and for creating for each specified object a local object locking procedure. The local object locking procedure includes a lock data subarray for storing theobject's lock data and instructions for updating a specified object's stored lock data. A lock data cleanup procedure, executed when the system's garbage collection procedure is executed, releases the local object locking procedure of a specified object if the object has not been recently locked.

Abstract: Methods for the fabrication of miniature electromagnetic microwave switches are disclosed in this invention. In one embodiment, on a dielectric substrate, miniature electromagnetic switches for coplanar waveguide transmission lines are fabricated. In another embodiment, miniature electromagnetic microwave switches are fabricated for microstrip transmission lines. The miniature microwave switches are built on a dielectric substrate and are accompanied by miniature electromagnetic coils on the back of the substrate. The switch is controlled by regulating the dc current applied to the electromagnetic coil. A switch is ON when a dc controlling current is applied to the electromagnetic coil and is OFF when the controlling current is cut off. A reverse dc current may also be applied to the electromagnetic coil to repel the top electrode so it does not touch the bottom electrode. The use of reverse current will prevent the two electrodes from sticking together and thus reduce the switching time. For the switch described in the second embodiment, the miniature electromagnetic coils are separated from the signal lines by a grounding metal layer fabricated within the substrate. In yet another embodiment, switches with two electrodes separated by a gap and a third element, a cantilever, are built on a dielectric substrate. Under the influence of a magnetic force, the cantilever will move downwards so that the two separated electrodes are connected.

Title: Spring applied parking brake actuator having a collet style slack adjuster
Inventor: MOORE ROLAND S
IPC: F16D65/28
Filed: 1997-10-02
Granted: 2001-05-29
Abstract: A brake actuator  for use on passenger transit railway vehicles.  The actuator includes a housing containing a service piston and a parking brake piston.   The service piston is connected to an inner hollow stem having a forward conical surface  disposed to  engage  a  conical  surface  of  a  collet provided on a threaded rod located within the stem.  The parking brake piston has a hollow outer sleeve surrounding the hollow stem, while a coil spring is located about the outer sleeve for applying a braking force when fluid pressure is removed from a housing containing the parking brake piston.  The spring expands against a locking ring located on a forward sleeve secured to an intermediate sleeve that engages the hollow stem.  This causes forward movement of the outer sleeve and forward movement of the conical portion of the hollow stem into engagement with the conical portion of the conical surface of the collet.  This, in turn, moves the threaded rod to engage brake applying components of a transit vehicle.
