Title: Attachment bracket for a liquid leakage sensor used in drain openings
Inventor: AKIBA JYUJI
IPC: G21D3/06
Filed: 1988-10-14
Granted: 1990-11-20
Abstract: UNITED STATES PATENT APPLICATION of JYUJI AKIBA for:                   AN ATTACHMENT BRACKET FOR A LIQUID LEAKAGE SENSOR USED       IN DRAIN OPENINGS                        Case No.: P-JUN-135 ABSTRACT OF THE DISCLOSURE An attachment bracket for attaching a liquid leakage sensor to a drain opening is provided. The attachment bracket has a funnel-shaped bracket body whose outer circumference is fitted in a liquid-tight relation inside the upper portion of the drain opening, this upper, tapered funnel portion being inclined downwardly toward a central opening leading to the drain. A generally circularly-cylindrical, "C"-shaped wall member of a prescribed height is installed on the upper funnel surface of the bracket body and extends around the circumference of the central opening of the bracket body except in the region of the opening of the "C" of the wall member, and a leak detecting sensor is attached to the bracket body within the opening of the "C" of the wall member. In use, a leak that enters the drain is blocked by the wall member and channelled by the wall member around to the opening of the "C", thereby concentrating the leak to the region of the sensor location more rapidly than would otherwise occur. In a preferred embodiment, a cap member is positioned over the open top of the "C"-shaped wall member to further channel and concentrate a leak toward the opening of the "C" in the wall member.

Abstract: ABSTRACT OF THE DISCLOSURE           A battery operated standby inverter power supply uses an electromechanical relay switching network to connect and disconnect line power between input and output terminals.          An overcurrent relay pulser rapidly opens the switching system relay contacts upon transition to battery mode, and a breakover diode network accelerates field collapse in the relay coil attendant to reversion of the relay to its normally closed condition attendant to each battery to line transition.          A fault detector establishes acceptable line voltage thresholds, the exceeding of either of which triggers operation from line to battery mode.   These triggering thresholds are automatically pulled closer together during initial system startup.   During system startup and attendant to each battery-to-line transition, the fault detector is momentarily latched to indicate acceptable line voltage conditions, thereby removing its susceptibility to transient retriggering.          During start-up mode a low-current transformerless power supply connected to the power line input terminals charges a storage capacitor sufficiently to power the fault detector through a single interrogation cycle, to actuate the switching circuitry to line mode operation if proper line voltage conditions are sensed.   Collapse of this capacitor voltage during this operation terminates the interrogation cycle, a new cycle begins when the capacitor has been suitably charged.  A overload detector senses the load current in line mode and prevents actuation to battery mode if the load connected to the power supply output exceeds the rated current value of the inverter.   A wiring detector prevents initial power-up to line mode in the event that the house wiring has miswired so as to interchange the house ground and the voltage return lines.

Abstract: BARBELL SYSTEM ABSTRACT OF THE DISCLOSURE: A barbell apparatus comprising a plurality of spaced weights stored on spaced apart support trays and arranged in two horizontal rows on a frame, the weights each having an identically positioned horizontal slot therein and a vertically disposed pin mounted therein for securing the weights to a lifting bar.  The lifting bar has a rotatable collar on each end with spaced circumferen-tial grooves in line with the pins in the weights.  The lifting bar has wheels which rest in a guide channel on each end of the frame and cooperate with a pair of spaced align-ment bars mounted on the frame to maintain the lifting bar in proper alignment with the frame and the weights during weight loading and unloading procedures.  Unselected weights are prevented from movement off the frame by a horizontal safety bar.  Two alternate embodiments of the weights used and the associated securing mechanism are provided.

Title: Read-write optical disk

Granted: 1994-04-19
Abstract: ABSTRACT        A read-write optical disk with a method of manufacture and configuration ofwriting mechanism.  The optical disk is fully configured at every readable location with pits filled with a stable, cyclable, solid-liquid (or solid-fluid) phase-change material, such as a paraffin mineral oil fraction, having specific reflectivity when in the solid state, and a layer of a particulate metallic material capable of being magnetically attracted or repelled and having a reflective value significantly different from that of the phase-change material.  The writing mechanism includes laser light amplification means to provide sufficient heat from the laser, which is used in the reading mode, to effect the solid-liquid phase change.  The writing mechanism further includes a material-moving magnetic element.  During operation of the write cycle, the phase-change material, in selected pits, is fluidized and is in the fluid state while a magnetic field is applied to the pit area.  As a result, the layer of particulate metallic material is magnetically moved through the fluidized phase-change material, either into or out of exposure to the laser used in the reading mode, thereby providing a significant change of reflectivity of the exposed surface of the individual pits.

Abstract: Abstract An orthodontic positioner appliance of elastomer base material is formed directly on the actual tooth attachments or coupling members during the fabrication process so as to assure accuracy of the appliance and its compliance with the exact shape and placement of the attachments or coupling members.  There is provided a construction model of the patient's teeth in a desired or ideal orientation, coupling members are attached to the facial and/or lingual surfaces of the teeth in the construction model, and the positioner is formed by applying positioner material to the construction model and directly to the coupling members thereby providing an exact adaptation of the positioner material to the construction model including the coupling members and providing an exact fit between the positioner material and the coupling members so as to eliminate any void or space between the coupling members and the positioner material to assure maximum purchase on the teeth but yet be easily removed by the patient. A first form of the positioner is formed by a hand lay-up or other appropriate technique providing a positioner body in the form of an elongated strip of silicone elastomer material having a length determined by the location of the coupling members and having a width initiating near the gingival line and terminating near the patient's opposing dental arch to avoid interference in occlusion, the body having a surface facing the teeth and recesses in spaced relation along the strip for snap fitting onto the coupling members, the positioner urging the patient's teeth to an exact fit between the recesses and the coupling members so as to eliminate any void or space between the coupling members and the recesses.  A second form of the positioner is formed by molding such an injection molding in a manner providing a positioner body of silicone elastomer material having an arcuate shape including a trough for receiving teeth of the dental arch, the trough having walls including surfaces having recesses in spaced relation along the trough for fitting onto the coupling members, the positioner urging the patient's teeth to an exact fit between the recesses and the coupling members so as to eliminate any void or space between the coupling members and the recesses to assure maximum purchase on the teeth but yet be easily removed by the patient.  In orthodontic treatment, coupling members are attached to the surfaces of the patient's teeth in a predetermined manner, only the first positioner is installed on the patient's teeth during a portion of the day when the teeth are most likely to be visible to others, and only the second positioner is installed on the patient's teeth during the remaining portion of the day when the teeth are least likely to be visible to others.  The coupling members are attached to the patient's teeth using a transfer matrix formed from the construction model with coupling members attached thereto.
