Abstract: A seat assembly having a front and a back and adapted to be attached to a floor comprises a seat base and a seat back attached to the seat base, a seat belt mechanism attached to the seat base and free of the floor, a blast mitigation device attached to the seat base and adapted to be secured to the floor, wherein the blast mitigation device has a crumple zone which absorbs energy in the event of a blast, and a front impact dislocation resistance device mounted on the blast mitigation device with a pair of brackets. The front impact dislocation resistance device acts to resist separation of the seat base from the blast mitigation device.

Abstract: A computer-implemented method of overseeing and adjusting the instruction and evaluation of a student with respect to one or more topics of study within a classroom. The subject matter of an academic course is studied and broken down into a plurality of discretely defined behavioral performances designed to be readily and objectively recognized as being mastered or not by a student. One or more of the discretely defined behavioral performances are then selected, with the aid of a first computerized database system, as learning objectives for the week. At the end of the week, a student is subsequently evaluated on these objectives. Results of the evaluation are then transferred to a second computerized database system, which organizes the collected data into an interactive learning management report that can be configured by a reviewer in real time to display a variety of levels of detail.

Abstract: A seal ring arrangement generally includes a pair of opposed seal rings which define a shaft seal to prevent leakage along the shaft of rotary equipment. A seal face treatment process has been developed using seal ring machining equipment which has a laser unit that forms micro-topography depth features in the seal face and then performs a material surface treatment process to selectively alter the conductivity of the seal face so as to virtually eliminate electro-corrosion in the seal rings. The seal rings preferably are provided in a conventional combination of a carbide seal ring material for one of the seal rings and a silicon carbide material for the other seal ring. The laser machining and the laser treatment processes are preferably applied to the silicon carbide material.

Abstract: The musical headwear includes headwear having a pocket that carries an electronic audio device. The pocket has an opening, sealable via fasteners disposed across fabric surrounding the top central portion of the opening. The electronic audio device is dropped into the open pocket and then sealed inside by fastening together the fasteners proximate the top central portion of the pocket opening. Gaps on either side of the seal are provided so that a user can touch the case of the electronic audio device, the case having a touch sensitive electronic pad that actuates the unit when momentarily touched by the user. When the unit is actuated, speakers embedded in the audio unit broadcast a song, chant, or other refrain that has been pre-stored in the unit's digital memory. The unit is factory programmed to play one or more different programs responsive to momentary user contact with the touch pad.

Abstract: A mount adjustable end cap clamp lock used with an adjustable light source with one or both ends collared by a barrel-type end, which is rotatable within an end cap. The end cap has a mounting surface that works in conjunction with a fastener to secure the lighting system to an object. The clamp pad, which may extend beyond the mounting surface, is slidable relative to the end cap. When the fastener is tightened, the clamp pad slides relative to the end cap to press against the barrel to lock the barrel in angular position and secure the light source from rotating when the fastener is tightened to secure the lighting system to an object. The end cap in conjunction with the clamp pad serves a dual purpose.

Abstract: An access control system with at least one entrance lane (4) has two or more antenna coils (12 to 15) arranged in pairs mutually opposing each other. Each antenna coil pair (12, 13 or 14, 15) is actuated by a reading device (20) for reading out a transponder (22) carried by the user, the transponder (22) having a transponder coil (24) coupleable with the antenna coils (12 to 15). The two mutually opposing antenna coils (12, 13 or 14, 15) of a pair are actuated at the same time, but alternately either in an in-phase or antiphase operation mode. For reading out the transponder (22) carried by the user the one operation mode, with which the transponder (22) is detected, is maintained until the reading transaction is completed.

During patterning of the semiconductor layer (4) the power of the laser (13) is so reduced that the front electrode layer (3) is not damaged.

Abstract: A mechanical seal face has a significant increase in the ability of the seal to tolerate poor lubrication conditions such as dry running. The mechanical seal employs a thin, non-corrugated flat sheet of flexible thermally conductive graphite material placed between one of the mechanical seal faces and a metal surface such as a metal surface defined by a shaft sleeve or gland serving as a seal ring holder. The graphite sheet is located axially between a back face of the more thermally conductive mechanical seal ring and the metal face holder part. The conductive seal face material preferably is a ceramic or cermet material such as silicon carbide, tungsten carbide, silicon nitride, aluminum oxide, or a metallic material such as stainless steel.

Abstract: A kiln having a body with an internal chamber accessible via an opening which normally is closed by a closure that is movable. Lift apparatus effects movements of the closure between its closed and opened positions. The lift apparatus includes an arm which overlies the closure and is pivoted to a support independently of the kiln body for rotation about a second axis that is spaced a selected distance from the axis about which the closure rocks. The lift arm is connected to the closure by a pivot coupling which maintains the lift arm and the closure substantially parallel and uniformly spaced apart throughout the movements of the closure. The pivotal connection of the lift arm to the closure enables relative movement of the lift arm and the closure during movements thereof to avoid imposing appreciable stress on either the arm or the closure.
