Abstract: A method for controlling process conditions in a continuous skull nozzle process is provided wherein one or more process parameters are controlled to maintain the opera-tion of the process within a process window derived using integral solutions and expressed in terms of dimensionless parameters, the process window defining a range of values within which a steady state solidified skull will be main-tained, and outside of which a steady state solidified skull will not be maintained. A pressure differential between the inside of a crucible holding the melt and outside the cru-cible is one process parameter which is controlled to adjust the melt discharge flow rate to maintain operation within the process window.

Title: Analog to digital converter
Inventor: LYDEN COLIN
IPC: H03M3/02
Filed: 1991-05-17
Granted: 1997-03-18
Abstract: A sigma-delta analog to digital converter 1 is disclosed .         The digital filter comprises a digital integrator (8, 10) for reception of  the negative  feedback  signal  of  the analog modulator.  The digital integrators (8, 10) are connected to replicate processing of the feedback signal by the analog integrators (3, 5).  Accordingly, the digital filter and the analog modulator may be reset simultaneously so that there is no time lag between conversion cycles.   Thus, single shot operation is achieved.

Title: Chemical ionization mass spectrometry method using notch filter
Inventor: KELLEY PAUL E
IPC: H01J49/42
Filed: 1992-02-11
Granted: 2000-05-02
Abstract: A mass spectrometry method in which notch-filtered noise is applied to an ion trap to resonate all ions except selected reagent ions out of the region (16) of the trapping field. Preferably, the trapping field is a quadrupole trapping field defined by a ring electrode (11) and a pair of end electrodes (12, 13) positioned symmetrically along a z-axis, and the filtered noise is applied to the ring electrode (11) [rather than to the end electrodes (12, 13)] to eject unwanted ions in radial directions [toward the ring electrode (11)] rather than toward a detector (24) mounted along the z-axis.  Application of the filtered noise to the trap in this manner can significantly increase the operating lifetime of such an ion detector.

Abstract: A method in conjunction with updating one or more HLR-databases included in a GSM-type mobile telephone system. Updating of an HLR (HRL1) is requested by sending a so-called Reset-message, which identifies the HLR-database concerned, to a number of VLR-databases. The losses in process capacity of the VLR-bases will be relatively small, because of the following: the time points (t:HLR1) at which Reset-messages and the time points (t:MS1) at which radio contacts were made with different mobile stations (MS1) are registered in each VLR. For each radio contact made between a VLR and a mobile station, a search is made in VLR to ascertain whether the mobile station belongs to an HLR which has been requested updating. If such is the case, the time point of the earliest preceding radio contact between the VLR and the mobile station is compared in VLR with the time point at which the Reset-message was received, wherein HLR is updated with data from VLR when the preceding radio contact occured before the Reset-message was received.

Granted: 2000-10-31
Abstract: A switching device is presented for the transmission of telecommunication signals between a telephone network exchange and at least one subscriber connected thereto, where the exchange is able to transmit metering pulses, in addition to the voice signal. The signals are transmitted as digital signals between the exchange and the subscriber via a two-wire line, which is connected with the exchange through a hybrid switching unit. To prevent the metering pulses from interfering with the voice signals, a parallel resonant circuit consisting of an inductance and a capacitor is connected to the two-wire system of the hybrid switching unit, and the receiving branch of the hybrid switching unit has an active and a passive filter connected in series. The passive filter is adjusted for the metering pulse frequency, and a filter that is tuned to the passive filter is used as the active filter, which compensates for a decrease in the NF (low frequency) level caused by the passive filter, with a corresponding increase.

Abstract: 23 The Recognition Training System (RTS) incorporates a new and innovative process which facilitates the training of a person to rapidly and accurately distinguish between members of a set of entitles, through the trainee interacting with RTS. The methodology of RTS involves the presentation of one or more attributes associated with an entity, while the trainee attempts to identify by name the entity, or the trainee may request that specific entities and associated attributes be shown for reference purposes. RTS supports an interactive training process which is almost completely self directed and affords a trainee an opportunity to make distinctions between similar entities by employing a two stage presentation facility. Attributes presented may be in the form of descriptive text, bitmap images, audio, and still and motion video.

Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure.  The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits.  The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network.  The papermaking belt is made by applying a coating of photosensitive resinous material to a reinforcing structure which has opaque portions, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions and also through the reinforcing structure.  A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers.  The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source.  Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.

Abstract: Obstacles are protected against collision in aisles adjacent mobile storage units with an IR transmitter mounted in spaced apart relation to an IR  receiver  on  a  unit.    For  initializing  and calibrating the system a microcomputer controls the transmitter to emit IR pulses of increasing width at a uniform repetition rate.  If there is no defect in the  system  the  receiver  responds  with  output electric pulses after the IR pulse width is reached that has the minimum integrated energy to exceed the input signal threshold of the receiver.  The minimum energy pulse width is stored in the microcomputer and the system switches to a run mode allowing storage units to move when commanded.  The computer responds to the absence of returned pulses from the receiver by inhibiting the system so the mobile unit will not run.   If returned pulses are not in the proper phase relationship the system goes into a diagnostic  mode  wherein the  interval  between transmitted IR pulses is reduced in increments for reasons including determining if there may only be temporary ambient IR interference.  If the problem does not clear up by the time the  interval  is reduced to one-half normal interval the system locks out.
