Abstract: A carbonization kiln for transforming pieces of raw material into charcoal. The kiln has an elongated container body formed by a peripheral wall and a pair of longitudinally opposed end walls. Each end wall has a fixed section and a pivoting section. The pivoting sections are adapted to be used for charging the raw material into the container body and removing the charcoal from the container body. Both the fixed section and the pivoting section of both end walls are provided with venting apertures extending therethrough. The venting apertures are adapted to act alternatively as air inlet apertures and combustion gas outlet apertures. A valve plate is pivotally mounted adjacent each venting aperture for controlling the flow of gas through the corresponding venting aperture. The container body is divided into two contiguous and substantially symmetrical carbonization half chambers by a dividing plate extending transversally across the container body and located approximately halfway between the end walls. The dividing wall is provided with a set of dividing wall apertures extending therethrough. The dividing wall apertures are configured and sized so as to prevent the migration of the content of the container body from one carbonization half chamber to the other while allowing the passage of gases and of the incandescent combustion plane through the dividing wall. The container body is pivotally mounted on a kiln stand so as to allow the container body to be pivoted about a pivoting axis that extends substantially in register with the dividing wall.

Abstract: An electronic test instrument adapted for displaying only meaningful information notwithstanding the intermittent arrival of valid input signals due to probing operations is provided. Two independent measurement processes measure the input signal simultaneously. The first measurement process operates in a similar fashion to a digital storage oscilloscope (DSO) by successively sampling the input signal to produce waveform information which are selectively sent to an LCD display device which graphically displays the waveforrn. The second measurement process continually performs a stability assessment of the input signal by collecting a series of stability measurements of a selected input signal parameter, creating a moving average of the series, and comparing each new stability measurement to the moving average relative to stability criteria. The stability decision controls the flow of waveform information to the display, thereby ensuring that only meaningful information is displayed based on waveform scans conducted when the input signal is stable.

Title: Dry polymer processing system
Inventor: PARDIKES DENNIS
IPC: B01F15/02
Filed: 1996-08-29
Granted: 2000-10-17
Abstract: A low cost dry polymer processing system has a housing containing submersible pump with a weir mounted on top of the housing and over an impeller chamber in the housing. The weir is a combination of a sleeve and a coaxial funnel with a top edge of the funnel that is level with respect to gravity to the extent that an inside wall of the funnel is wetted with an unbroken sheet of liquid. An electrolyte liquid rising in the sleeve overflows the top edge of the funnel in order to form a liquid sheet or curtain uniformly covering the inside wall of the funnel. The amount of liquid is limited so that the impeller is not hydraulically locked. Dry polymer is dropped through the funnel and into the eye of the impeller enclosed within the chamber which is drained via a port in the bottom of the pump housing. Fresh electrolyte is introduced into the housing at a level which is under the impeller. Thereafter, the mixture of the electrolyte and polymer is drained from the impeller compartment via the port. Before the mixture is completely discharged from the housing, another supply of fresh electrolyte is introduced into the draining mixture.

Filed: 1997-03-10
Granted: 2000-06-20
Abstract: An adaptive high speed data transmission system is described.  In one aspect, the transmitter for this system employs a plurality of transmit antennas which have controllable offsets.  The tranmsitter also includes signal coding circuitry suitable for use to address transmission impairments due to fast fading in the transmission channel.  At the receiver, the received signal is analyzed to determine the fading characteristics of the channel.  Where slow fading is detected, the offsets are employed to convert the slow fading into fast fading.  The channel characteristics are continually resampled and these characteristics are used to adjust the transmitter and the receiver to achieve optimal transmission speed.
