Abstract: An electrically operable valve assembly having an integral pressure regulator provides ease of installation and compact packaging for a water supply control system. The valve assembly is particularly useful for systems that control household water supplies to prevent flooding, but is also useful in other applications such as agricultural and industrial systems where water pressure determined water flow volume must be predicted accurately. The valve may also incorporate a flow meter having a positive flow characteristic permitting determination of very low flow rate flow and the valve may incorporate a manual control. All of the controls and features are integrable within a compact package that occupies essentially the same volume and piping space as a conventional electrically operable valve.

Abstract: A dual compartment tire has a primary air compartment and a secondary air compartment that is internal to the primary air compartment. During ordinary travel, the primary air compartment is in contact with the road surface, with the secondary air compartment constituting an integral spare tire in the event of a flattening of the primary air compartment. Each of the primary and secondary air compartments is bounded by an exterior surface. In contrast to prior art dual compartment tires, the exterior surface of the secondary air compartment is relatively thicker than the exterior surface of the primary air compartment.

Abstract: A flow meter and electrically operable valve assembly having integral flow meters provide detection of very low water flows, along with ease of installation and compact packaging for a water supply control system. The flow detection is particularly useful for systems that control household water supplies to prevent flooding, but is also useful in other applications such as agricultural and industrial systems where low water flow rates must be determined. All of the controls and features are integrable within a compact package that occupies essentially the same volume and piping space as a conventional electrically operable valve.
Abstract: A writing aid for helping to steady a hand of an individual to allow the individual to write in a more steady manner has a writing pad. The writing pad has a magnetic layer. A writing instrument is provided wherein the writing instrument has at least one magnet coupled to a bottom section of the writing instrument. The magnetic attraction between the magnet and the magnetic layer will steady the hand of the individual using the writing aid. The writing instrument is adjustable so that the individual can adjust a distance a writing tip of the writing instrument is deployed. By adjusting the length of the writing tip that is deployed, the individual can adjust the magnetic attraction between the magnet at the bottom section of the writing instrument and the magnetic layer.
Abstract: A toilet paper dispenser is disclosed which contains a spool that extends at a right angle from a mounting plate secured to a surface. The mounting plate may, optionally, be mounted to a wall surface or may be recessed. The spool receives a roll of toilet paper thereon, and has an end cap that is removably coupled to an end of the spool, after placement of the toilet paper roll on the spool to prevent the roll from coming off of the spool. The toilet paper dispenser includes a top cover positioned so as to conceal a top portion of the toilet paper roll when the mounting plate is mounted on a wall surface. When a drywall type surface is used, a butterfly type anchor permits attachment of the mounting plate to the drywall type surface.
Abstract: A telephone line connection and disconnection circuit has a diode bridge coupled to the telephone line which converts different voltages of the telephone line into a voltage referenced to ground. A switching circuit is coupled to the diode bridge which opens and closes a conductive pathway for connecting and disconnecting a telephony product from the telephone line. A resistive element is coupled to the diode bridge and the switching circuit which allows for the conductive pathway to be normally closed. An optical isolator is coupled to the switching circuit and the resistive element for sending a control signal to the circuit when required.
Abstract: A rotor of a synchronous motor and a method of manufacturing the same. The rotor of the synchronous motor comprises a main core, formed from a plurality of laminated thin iron sheets, the thin iron sheets having a hole at a center for receiving a rotating shaft, and a number of magnet holes and induced conductor holes radially disposed in the thin iron sheets at a predetermined space differently from the hole. A plurality of magnets are inserted into the magnet holes of the main core. Supplementary cores, having a hole and induced conductor holes corresponding to the hole and the induced conductor holes of the main core, are disposed at the ends of the main core wherein the magnet is inserted. An induced conductor formed by ingoting through the induced conductor holes of the main core and the induced conductor holes of the supplementary cores. Consequently, through the induced conductor and the magnet, the efficiency of the motor can be improved.
Abstract: A method and system for performing swept-wavelength measurements within an optical system provides improved operation in resonator-enhanced optical measurement and data storage and retrieval systems. The system includes an illumination subsystem having a swept-wavelength mode, a detection subsystem, an interferometer or an optical resonator interposed in an optical path between the illumination subsystem and the detection subsystem and a time domain analysis subsystem. Multiple resonance points of the optical resonator are detected by the time-domain subsystem when the illumination subsystem is in the swept-wavelength mode in order to determine resonator or interferometer characteristic changes. The resulting information can be used directly as a measurement output, or cavity length information may also be used to adjust the operating wavelength of a constant wavelength mode of the illumination subsystem.

Abstract: A locking lid and method for a valve box. The locking lid has a closure and surrounding external seal, which fit into the valve box opening and close/seal it. The locking mechanism of the locking lid preferably consists of an actuator spindle that extends through the closure, and that is received in an actuator follower positioned therebelow. The actual follower is in pivotal engagement with a plurality of locking pawls, such that turning of the actuator spindle causes movement of the actuator follower and thus pivoting of the locking pawls—moving the locking pawls into a locked or unlocked position relative to a lid seat within the valve box.
