Abstract: An arc tube comprises a light transmissive body containing an arc generating andsustaining medium and has a press seal formed at one end of said body. The press seal comprises a planar portion separating opposed edges. A first foil is sealed in the planar portion. A lead-in conductor is attached to the foil and extends outside of the body and an electrode is also attached to the foil and extends inside the body. A first cavity is formed on a first of the edges and a second cavity is formed on a second of the edges. A fill is provided in each of the cavities for supporting emission of ultraviolet radiation; and a second foil sealed in the planar portion is attached to the first foil, said second foil having a first end terminating in the first cavity and a second end terminating in the second cavity. A ground plane is provided adjacent the cavities. A high voltage pulse applied to the electrodes, and, thus, the foils, creates a capacitive discharge creating the ultraviolet radiation which aids in starting the lamp in which the arc tube is employed.

Abstract: A method for detecting translation data error in a central office switch comprises: receiving a call directed to a ported directory number in a switch; retrieving translation data from the switch memory to connect the call to a customer line; and determining that the call cannot be completed to a customer line served by the switch. Upon determining that the call cannot be connected to a customer line served by the switch, a translation data error (TDE) indicator is set in the switch memory so that the instant call, and all subsequent calls directed to the same ported directory number, are connected to an announcement circuit. An translation data error message is also sent to a central switch maintenance and control center by the switch.

Filed: 1995-09-19
Granted: 2000-03-07
Abstract: A method and apparatus for sampling and measuring a physical property of a product in a container (11). The container (11) has an aperture (11a) in its bottom surface, to which a sampling tube (13) is affixed. A piston (14) moves back and forth in the sampling tube (13), thereby withdrawing and replacing samples of product via the aperture (11a). While a sample is in the sampling tube (13), a sensor (15) senses a measured value of the physical property of interest. The piston (14) has a calibration layer (14a) that is made from a material having a property that is similar to that of the product with respect to the property of interest. For calibration, the piston (14) is positioned so that the sensor (15) senses a measured value that can be compared to a reference value to determine if the sensor output is properly calibrated.

Abstract: Within a differential detection demodulator, a received signal is first quantized by a limiter amplifier and then subjected to frequency conversion by a frequency converter.          The frequency converter circuit converts a frequency of a first 2-level signal using a second 2-level signal having a frequency distinct from the frequency of that first signal, and includes: an exclusive OR element for obtaining a logical exclusive OR element of the first and second signal; running average generator means, coupled to the exclusive OR element, for generating a signal corresponding to k times a running average of an output of the exclusive OR element, k being a positive integer; and hard decision means, coupled to the running average generator means, for converting an output of that running average generator means to a 2-level logical signal.  In response to the output of the frequency converter, a phase comparator outputs a relative phase signal representing the phase shift of the received signal after frequency conversion relative to the phase reference signal.

Abstract: A compressor has a drive plate located in a crank chamber and tiltably mounted on a drive shaft and a piston operably coupled to the drive plate and located in a cylinder bore. The inclination of the drive plate is variable according to a difference between the pressure in the crank chamber and the pressure in the cylinder bore.  The compressor has an adjusting mechanism for adjusting the pressure in one of the crank chamber and a suction chamber to vary the difference between the pressure in the crank chamber and the pressure in the cylinder bore.  The adjusting mechanism includes a gas passage for passing the gas used for adjusting the pressure and a control valve for adjusting the amount of the gas flowing in the gas passage.  The control valve includes a valve body, a reacting member and a solenoid.  The valve body adjusts the opening size of the gas passage.  The reacting member moves the valve body in accordance with the pressure of the gas supplied to the compressor from the external circuit.  The solenoid biases the valve body in a direction with the force based on a value of current supplied to the solenoid.  A supplying apparatus supplies undulating current to the solenoid.  The supplying apparatus varies the average value of the undulating current to vary the biasing force of the solenoid.

Abstract: A hydrous resin composition suitably employed in producing preexpanded polyolefin resin particles, which contains a polyolefin resin and a hydrophilic polymer and which has a water content of 1 to 50 % by weight; and preexpanded polyolefin resin particles obtained by preexpanding the hydrous resin composition and having an apparent expansion ratio of 5 to 60, a closed cell ratio of 80 to 100 %, and an average cell diameter of 50 to 500 µm.  The preexpanded particles can be produced without the use of a volatile expanding agent by dispersing resin particles produced from a resin composition containing a polyolefin resin and a hydrophilic polymer in a water-base dispersion medium in a closed vessel to thereby form a dispersion, heating the dispersion at a temperature not lower than the softening point of the polyolefin resin to thereby form hydrous resin particles having a water content of 1 to 50 % by weight and releasing the water-base dispersion from the closed vessel into an atmosphere of a pressure lower than the internal pressure of the closed vessel to thereby expand the hydrous resin particles.  When the release of the dispersion from the closed vessel is conducted after introducing nitrogen gas, air or an inorganic gas composed mainly thereof into the closed vessel so that the internal pressure is set to be 25 - 75 kg/cm2G, preexpanded particles capable of providing foams of a high expansion ratio and excellent properties can be obtained.

Title: Pricing control system for multi-operation vending machines
Inventor: BROKER JOHN F
IPC: G07F7/00
Filed: 1998-10-30
Granted: 2005-03-22
Abstract: A pricing control system for multi-operation vending machines, such as those commonly found in laundromat facilities, incorporates an offset price setting field for storing at least one incremental offset price which is added to a pre-established base price in order to set the cost for a respective vending machine operation. In accordance with a first preferred embodiment of the invention, a single offset price is used to increment each of the base prices established for a given vending machine such that the costs associated with each of the operation is incremented an equal amount. In accordance with another embodiment of the invention, multiple offset amounts are stored and added to predetermined base prices to establish the cost of each of the respective vending machine operations. The price control system is considered to be particularly advantageous when utilized in connection with a debit card charging arrangement and enables facility operators to change the numerous vending machine operation prices by only altering the data stored in the offset price setting field. In addition, the use of the pricing control system of the present invention readily enables penny increment price changes to be implemented in existing vending machine facilities.
