Granted: 1999-12-14
Abstract: A method for manufacturing reclosable packages on a form, fill and seal machine includes the step of providing a continuous sheet of thermoplastic material with  a  Z-fold extending longitudinally therealong before the sheet is wrapped around a filling tube for forming and filling the packages.   The Z-fold is maintained on the tube of thermoplastic material thus-formed until it reaches a loop opener on the outside surface  of  the  filling  tube.    The  loop opener transforms  the  Z-fold  into  a  loop  extending longitudinally along and outwardly from the filling tube and  from the tube of thermoplastic material wrapped therearound.   Simultaneously,  a continuous plastic zipper having a pair of mutually interlocking profiles is directed into the tube of thermoplastic material along a channel on the outside surface of the filling tube.   The zipper is ultimately guided out from the channel, through the loop opener and into the loop, and is sealed thereto to form the reclosable openings for the plastic packages being manufactured.

Title: Centrifugal separator in pressure vessel
Inventor: ERIKSSON TIMO
IPC: B01J8/38
Filed: 1994-12-09
Granted: 1999-11-09
Abstract: A pressurized fluidized bed reactor is provided utilizing a centrifugal separator having a gas space that is distinctly noncircular, preferably having a circularity of greater than or equal to 1.15. Most desirably the cyclone has a quadrate (e.g. square) cross section, and is disposed inside the pressure vessel along With the reactor chamber containing the fluidized bed. A number of ceramiccandle or honeycomb filters may be provided connected to the gas outlet from thecyclone separator, within the pressure vessel, to filter the gas. This construction provides a minimized diameter of the pressure vessel because the reactor chamberwith square cyclones is more compact than if conventional circular cross sectioncyclones are employed. Also a second pressure vessel is not needed for the candle or honeycomb filters since there is sufficient room within the pressure vessel to accommodate them.

Granted: 2000-05-09
Abstract: An available frequency range previously assigned to the communication system is divided into a plurality of subranges each including a plurality of frequency channels to which channel identifiers are assigned, respectively. The channel identifiers are repeatedly assigned to all the frequency channels in the subranges. In such a channel assignment, a transmitting side transmits a signal including a desired channel identifier corresponding to a desired frequency channel.  At a receiving side, after detecting a frequency acquisition of the demodulator, the desired channel identifier is detected based on the received signal when the frequency acquisition of the demodulator is detected. When the frequency acquisition of the demodulator is detected and the desired channel identifier is detected, a local oscillation frequency sweeping for demodulator is locked to receive the signal from the transmitting side.

Title: Apparatus for controlling an ozone generator
Inventor: TERADA MITSUO
IPC: G05B23/02
Filed: 1998-06-09
Granted: 2001-08-21
Abstract: The invention provides an ozone generator controlling apparatus capable of controlling an ozone generator so that when a discharge breakdown occurs in some discharge element, the operation of generating ozone can be continued without imposing a bad influence on the remaining normal discharge elements. When an anomaly occurs in one of or a plurality of discharge elements during the operation of generating ozone, the anomaly is detected by an anomaly detection means. In response to the detection of the anomaly, first output control means reduces the output of an AC power supply circuit to a sufficiently low level so that after the discharge element having the anomaly is isolated from the circuit the operation of generating ozone can be continued with the remaining normal discharge elements without interruption and without causing the normal discharge elements to encounter an overload current thus preventing them from being broken one after another. The discharge element having the anomaly may be isolated using nondestructive current cut-off means such as a high-voltage relay. In this case, the current cut-off means can be used for a very long time without having to replace when a breakdown occurs in some discharge element, unlike the case where a fuse is used as the current cut-off means.      When an anomaly occurs in some discharge element, instead of immediately isolating it from the circuit, the output of the AC     power supply circuit may be reduced using second output control means until the current detected by the current detection means becomes lower than the predetermined upper allowable limit. This makes it possible to continue the operation of generating ozone without isolating the discharge element having the anomaly.

Abstract: Demodulating FM signals using digital signal processing extracts a carrier signal from digitized channel signals, multiplies the digital channel signal with this extracted carrier signal, and further filters out the carrier signal to produce the demodulated signal. The DSP technique first down converts a group of channels to baseband which are then processed through an A/D  converter to produce a digitized composite signal. A bank of bandpass filters, typically based on FFT processors, applied to the composite signal produce (a group of) digitized channel signal(s). The digitized channel signal is then demodulated by recovering a carrier signal by digitally filtering, for example, using a Hilbert bandpass filter, the channel signal and digitally filtering the product of the carrier signal and the channel signal to recover the modulating voice signals.
