Title: Dynamic pricing method and apparatus for communication systems
Inventor: HILLIS DURRELL WAYNE
IPC: H04M17/02
Filed: 1992-03-30
Granted: 2002-08-20
Abstract: A communication system service billing arrangement is described that adapts to system loading in realtime. As system loading varies, one or more individual subscribers units (ISU) of a communication system are provided with realtime information on the current cost of the communication service. The system determines the locations of the ISUs and the current loading there between and calculates a calling rate based at least on the current loading. This calling rate is sent to at least one of the ISUs whose operator can choose to connect or not connect the call between the ISUs based on the current realtime variable rate.

Title: End cap for cooling coils of an electric arc furnace
Inventor: JOHNSON ERIC N
IPC: F27D1/12
Filed: 1992-06-15
Granted: 2004-05-25
Abstract: An end cap is provided for adjacent pipes in the cooling coils of an electric arc furnace. Each end cap includes parallel opposite side walls and a curved end portion connecting the side walls. The side walls and end portion define a perimeter edge, the outer portion of which is beveled.

Title: Method of suppressing torsional vibration in a motor speed control system and apparatus therefor
Inventor: SHIBATA NAOTAKE
IPC: H02P25/098
Filed: 1992-02-05
Granted: 2001-12-18
Abstract: Herein disclosed are a method and an apparatus for suppressing a torsional vibration in an electric motor speed control system including a mechanism for transmitting a drive torque from an electric motor to a load through a drive shaft having a torsional spring system. Generally speaking, the signal of a speed detector (3) of an electric motor is a pulsating signal of high frequency. Even if this speed detecting signal is differentiated, it is impossible to obtain a signal proportional to the changing rate of the motor speed. By computing an average value of the signals of the motor speed detector (3) for every predetermined period, however, the pulsating value of the speed signal can be reduced to compute the changing rate of the motor speed from that signal. In the present invention, an acceleration torque command of the electric motor is given in terms of the output signal of a speed controller (11) to cancel the load torque of the electric motor from disturbing the acceleration torque of the motor, with the torque command compensating signal outputted from a motor acceleration torque controller (25) having a proportional gain and an integrator. As a result, the disturbing torque of the electric motor, which is generated by the load and the torsion of the drive shaft during an acceleration and at an abrupt load fluctuating time, is canceled so that the torsional vibration is suppressed to stabilize the variable speed characteristics.

Inventor: GREV ANN HOFFMAN
IPC: A23L1/308
Filed: 1993-08-12
Granted: 2004-10-19
Abstract: The present invention relates to a modified fiber material, preferably a legume or cereal grain fiber and most preferably a soy fiber material, which is characterized by an increased level of soluble dietary fiber and improved physical characteristics. The modified fiber is produced by a process which comprises forming a slurry of a fiber material, typically a soy fiber such as the spent flake residue derived from soy isolate processing, which typically has a relatively low percentage of soluble dietary fiber. The pH of the slurry is adjusted below about 4.5 by the addition of an edible acid. The pH adjusted slurry is then heated at a temperature and for a period of time sufficient to increase the soluble dietary fiber content, usually to a level of about 30% or greater of the total dietary fiber content in the case of soy fiber. Following modification, the modified fiber is dewatered to provide a food ingredient that has improved textural properties as an additive to beverages, soups, creams, emulsified meats or other types of food products.

Granted: 1998-01-06
Abstract: This arterial blood monitoring system takes advantage of the basic statistical property that arterial blood contains a plurality of dominant absorbers, whose measured light absorption spectra appear as a constant over a short interval of time. By measuring the transmitted light as it varies with arterial pulsation at selected wavelengths of light, over a common light path, the relative amount of these dominant absorbers in the arterial blood can noninvasively be determined. To ensure the common light path, a sandwich construction light detector is used.

Title: Selectively actuatable lighter
Inventor: MCDONOUGH JAMES M
IPC: F23Q2/16
Filed: 1993-10-22
Granted: 2001-08-07
Abstract: A selectively actuatable lighter device (10) is disclosed which includes a body defining reservoir (12) for containing a com-bustible gaseous medium such as butane, and having a valve (20) arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium.  Such lighter (10) can selectively produce sparks at a location (19, 22) proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter device (10) embodies a resi-liently releasable valve actuator (14) which normally prevents actuation of the valve (22). The valve actuator (14) includes an inter-fering portion (14A) which is selectively movable to a position (figure 14) out of interference with an interfering portion (27) of the lighter body, so that the gaseous medium may be released and ignited by the sparks. Once the valve actuator (14) is depressed and released, it returns to its closed or latched position to prevent actuation of the valve to the open position. To "re-use" the ligh-ter, the valve actuator (14) must again be moved to an unlatched position so that the valve (22) can be actuated for subsequent ig-nition of the gaseous medium.
