Title: Fifo queue having replaceable entries
Inventor: FERGUSON PATRICK L
IPC: G06F5/10
Filed: 1995-02-10
Granted: 1999-01-05
Abstract: A FIFO queue is utilized to provide control information to the appropriate time slot in a time multiplexed serial link between an interface chip and a CODEC.  The FIFO queue allows rewriting or replacement of any control registers present in the queue without requiring that a new entry be placed in the queue.  A particular control register which is placed in the queue then maintains its place as the queue is emptied, even though the control register may be written one or more times while the control register entry is in the queue waiting for transmission to the CODEC.  The loss of the prior command information is not a problem as the data rate of the serial link is still sufficiently high so that any minor transitory change which may have been desired would be of minimal effect in any regard and would have been inaudible to the human.

Title: Proportional chemical feeding system
Inventor: SCHRANDT HENRY M
IPC: F04B49/00
Filed: 1996-04-11
Granted: 2007-07-10
Abstract: A treatment system is described having a controllable pump with an automatic calibration and measuring system. Pumped volume can be determined during each cycle using a fluid flow measuring device and a controller. The fluid flow measuring device has a totalizer counter, and batch measurement capability. For each batch, the fluid flow measuring device sends a ready signal to the controller. The controller sends a start signal to initialize the totalizer counter and tells the totalizer to start flow measurement. When the totalizer value equals the batch value, a batch complete signal is sent, defining a predetermined volume by which the controller measures and automatically calibrates the system. The controller determines the number of cycles of the pump required to pump the predetermined volume, and determines deviation from a pre-established number. The pump responds to the detected deviation.

Title: Atv/mpeg sync system
Inventor: FIMOFF MARK
IPC: H04N7/24
Filed: 1996-04-03
Granted: 2001-06-05
Abstract: An ATV system encodes variable length elementary streams of data into a multilevel symbol signal comprising a plurality of multiplexed fixed length data packets without sync information. The fixed length data packets are arranged in fields of repetitive data segments, each of which includes a data segment sync and each field of which includes a field sync. The fields of data segments are transmitted as suppressed carrier VSB modulation. In an ATV receiver, the data segment sync is used to generate a timing signal that identifies the beginning of each fixed length data packet.      In one embodiment, a packet sync signal is inserted into each recovered fixed length data packet for recovering the elementary streams of data. In another embodiment, recovery of the elementary streams of data is accomplished without inserting a packet sync signal.

Abstract: A method and a system are disclosed for the suppression of foams during the processing of streams containing waste materials. An additive is introduced into a waste stream and the waste stream is processed for a period of time at an elevated temperature and substantially atmospheric pressure.
