Patent EP-0572202-A1 (EP)
Inventor: BLACK STEPHEN H
IPC: F23R3/28
Filed: 1993-05-25
Abstract: A lean burn gas turbine combustor has a premixer zone receiving compressor discharge air through openings in a combustor liner. A fuel nozzle has an upstream orifice 52, a downstream orifice 56, and a captured response volume 54 therebetween. Upstream orifice 52 affords a high pressure drop for gaseous fuel to approximately the pressure of the compressor discharge air. The low pressure discharge orifice affords a pressure drop comparable to the pressure drop across the openings of the combustor liner for the air supply. The dynamic pressure response characteristics of the fuel and air inlets to the premixer zone are substantially matched to eliminate variations in fuel/air concentration resulting from pressure variations in the premixer zone. The captured response volume between the upstream and downstream orifices is sized sufficiently to store enough fuel to accommodate the mismatch in phase angle of fuel flowing into the captured response volume through the upstream orifice at a first phase angle relative to the phase angle of a pressure forcing function in the premixer zone and fuel flowing out of the captured response volume through the downstream fuel discharge orifice at a second phase angle relative to the phase angle of the pressure forcing function.

Abstract: A tapping attachment for use in connection with radial tapping comprises a tap spindle member (34) rotatable in a tapping direction, a driven part (20) engageable with a driving (16) part from a power source in a different direction from the tapping direction, a forward drive member (28) engageable with the tap spindle member (34) to drive the tap spindle member in the tapping direction, a reverse drive member (30) engageable with the tap spindle (34) to drive it in a direction opposite to the tapping direction, means (24,26) for transmitting drive to the forward drive member (28) and the reverse drive member (30) and engageable with the driven part (30) for receiving drive and with the tap spindle member. The forward drive member (28) and the reverse drive member (30) are moveable axially along the tapping direction relative to the tap spindle member (34) and upon relative axial movement in a direction opposite to the tapping direction, the forward drive member disengages from the tap spindle member and the reverse drive member engages in driving engagement with the tap spindle member to impart reverse rotation to the tap spindle member.

Abstract: Lower, arced decurling guide (1) is pivoted on pin (3) and biased upward by spring (7). Upper stop (11) prevents the lower guide from moving closer to upper decurling roller (15). Paper (9) is guided between these upper and lower guides and the lower guide is moved outward in proportion to the rigidity of the paper being decurled. This automatic adjustment provides good decurling for all papers within a broad range of rigidity.

IPC: A61B18/00
Filed: 1993-11-15
Abstract: Ultrasonic sensing systems are incorporated into surgical instruments to monitor operational fields defined by distal ends of the instruments. The instruments include proximal ends for their activation typically including one or a pair of handles which a surgeon grasps and operates, for example by squeezing the handles together or by pivotally moving a trigger portion of the handle relative to a fixed portion of the handle. Circuitry for performing ultrasonic sensing preferably is enclosed in housings defined within the handles of the proximal ends of the instruments. Wiring, preferably running through the instruments, connects the circuitry to transducers formed in or mounted on the distal ends of the surgical instruments. The transducers direct ultrasonic energy to the operational fields defined by the distal ends of the instruments and receive ultrasonic energy reflected from the operational fields. The direction for transmission and receipt of ultrasonic energy is determined by acoustic lenses, angularly oriented transducer mounts or a combination of the two. Signals representative of the tissue or contents of the operational fields of surgical instruments drive audible signal generators or preferably tactile transducers to inform the surgeon of the contents. Tactile transducers are mounted for access by the surgeon, preferably on the handles of the surgical instruments.

Abstract: A linear actuator comprises a threaded spindle (1) rotatable in either direction, a threaded bushing (3) that drives an output rod (4) and a reversible motor (5) that drives the spindle via a power transmission (6). In certain cases such as hospital beds it might be desired instantly to arrive at one or the other extreme position or an intermediate position from any position. This is achieved by disconnecting the power transmission from the spindle which is not of the self locking type. In a gear transmission having a pair of bevel gears (8, 9) the power transmission may be disconnected by pulling the gear (9) on the drive shaft out of its engagement with the other pair of gears. The gear (9) is axially displacable along the drive shaft, but mutually locked in the rotation for instance by a driver unit or polygon. The construction offers the advantage of being instantly operational from the connected position.

Abstract: A child resistant attachment for containers used for storing and dispensing potentially dangerous materials, such as medicament tablets or the like, the attachment being resistant to opening by children but readily openable by adults, particularly adults having impaired manual dexterity of their hands and/or fingers. In a particularly preferred embodiment, the attachment comprises a finish portion including thread ring with an integrally molded annular tab ring or collar generally concentric to the thread ring and a closure which is releasably secured to the thread ring by means of complementary screw threads. The tab ring or collar preferably includes a pair of resiliently deformable spring-like pushtabs containing vertical extensions which engage interlocking pawls on the innermost surface of the closure skirt when the closure is fully assembled onto the finish portion. To remove the closure, the opposed pushtabs must be depressed prior to applying unscrewing torque to the closure to disengage the pushtab extensions from the interlocking pawls on the closure. In a particularly preferred embodiment, the finish portion of the child resistant attachment of the present invention is integrally molded with the container in a ready to use configuration without the need for additional assembly or molding operations. Methods for producing the child resistant attachment and child resistant packages employing it are also disclosed.

Date Aug. 19, 1993A process for preparing amorphous ultrahard material based on boron nitride which has a hardness sufficient to scratch diamond uses hexagonal or turbostratic boron nitride hBN as starting material. The starting material is compressed at pressures of at least 70 Kbar and heated to temperatures of at least of 1650 DEG  C. until a boron nitride melt is obtained, the boron nitride melt is quenched by shutting off the heat supply and the quenched boron nitride melt is then relieved of the pressure. In the process, the hexagonal or turbostratic boron nitride employed as a starting material is treated in the presence of crystallisation inhibitors so that the formation of crystals is completely prevented and an amorphous structure is compacted by incorporation of reaction products comprising boron suboxides.

Abstract: Disclosed is a class of light modulating materials comprising microdomains of ferroelectric smectic liquid crystal dispersed in a light-transmissive polymer medium. The microdomains are formed by phase separation of the liquid crystal from solution with the polymer as the polymer is solidified. The switching of the liquid crystal may be either monostable or multistable ( e.g. , bistable), depending on the liquid crystal and polymer. The material modulates light in either a scattering-transmissive mode or a birefringence mode. Materials operating in the scattering-transmissive mode do not require polarizers. Advantages of the materials include switching times down to the order of microseconds or less, multistable optical states, wide viewing angles and high contrast.
