Title: Method and apparatus for deaerating a liquid in a substantially closed liquid circulation system
Inventor: ROFFELSEN FRANCISCUS
IPC: B01D19/00
Filed: 1994-10-25
Abstract: A method and apparatus for deaerating a liquid in a substantially closed liquid circulation system, wherein an amount of liquid is withdrawn from the circulation system and is introduced into a closed reservoir via a valve which is alternately open and closed, wherein by means of a pump which is operative in the open as well as the closed positions of the valve an underpressure can be created in the reservoir for the purpose of deaerating the liquid, and the liquid can be sucked from the reservoir and added to the circulation system again, separated air being discharged via a vent unit to the environment. For the valve adapted to be opened and closed alternately, preferably a throttling valve is used.
Patent CA-2137887-A1 (CA)
Inventor: WILSON MATTHEW A
IPC: B26D7/18
Filed: 1994-12-12
Abstract: A die roll and air manifold system comprising a rotary die roll rotatable in a press, and an air manifold having a cylindric body positioned in a central bore in the die roll.  The cylindric body of the air manifold has an outside diameter only slightly less than the diameter of the bore.  A pair of shafts extend coaxially from opposite ends of the cylindric body beyond respective ends of the die roll for mounting of the air manifold and die roll on a press. The manifold shafts have outside diameters less than the diameter of the central bore in the die roll and less than the outside diameter of the cylindric body of the air manifold.  Axial passaging in the air manifold is provided for connection at its inlet end to a source of pressurized air.  One or more air outlet passages in the body of the air manifold extend from this axial passaging to the outer surface of the manifold body.  These passages are positioned for intermittent alignment with radial outlet passages in the die roll as the die roll rotates relative to the air manifold thereby to effect the intermittent delivery of bursts of pressurized air through the air outlet passages in the die roll to remove scrap material from cutters on the outer surface of the die roll.

Title: Compact c-arm tomographic bone scanning system
Inventor: MAZESS RICHARD B
IPC: G01V5/00
Filed: 1993-11-12
Abstract: 2148912 9410908 PCTABScor01 An x-ray imaging system provides both scanning radiography and computed tomography by means of a modified C-arm geometry that provides improved angular rotation. Estimation techniques are used to produce missing projections of the complete tomographic projection set, and a limited size detector (50) reduces the amount of data required for reconstructing tomographic images of compact objects of unique composition within the patient (such as the spine (65)). The introduction of image artifacts caused by external volumes to the field of view is reduced by employing dual energy techniques to isolate the internal structure from the external volumes.

Patent CA-2149510-A1 (CA)
Inventor: MORITA SHIGEKI
IPC: F23D17/00
Filed: 1991-06-27
Abstract: A combustion apparatus comprises a mixture feeding pipe (1) through which a mixture of pulverized coal and combustion air flows. The mixture is injected into a furnace (2) through the mixture feeding pipe and then ignited. A radial outwardly flared flame maintaining ring (3) is provided at the tip end of the mixture feeding pipe. The flame maintaining ring is under a reduction atmosphere and exposed to high temperatures due to radiant heat from the furnace. Therefore, there is a possibility of burnout of the flame maintaining ring or growth of slag on the flame maintaining ring. In order to prevent this, a projection (6) is disposed to extend into the furnace beyond the flame maintaining ring so as to shut off radiation from the inside of the furnace to the flame maintaining ring adequately, thereby suppressing an excessive temperature rise. Combustion air flows along the surface of the projection so as to locate the projection under an oxidation atmosphere. A pulverized coal/air separating member (7) extends through within the mixture feeding pipe. A portion where separation of the flow is forcibly occurred is formed locally in a conical end portion (II) of the pulverized coal/air separating member. It is therefore possible to effect a combustion in a stabilized manner as a whole regardless of the unit capacity and load of the combustion apparatus. <IMAGE>

Abstract: Adaptive apparatus for eliminating interference from a received signal provided on a transmission line caused by radio transceivers includes a plurality of frequency tunable filters tuned to the operating frequency of a corresponding transmitter.  The transmitter signal of each transmitter is provided to a corresponding filter.          The filter eliminates the non-essential transmission of harmonics, intermodulation and wideband noise of the transmission signal.   The adaptive apparatus includes a plurality of cancellation devices wherein each cancellation device receives a sample of each filtered transmission signal and the received signal.  The received signal includes an error portion generated by the transmitters and a non-error portion corresponding to the signal received by the antenna.  Each cancellation device compares the corresponding sampled transmission signal with the sample of the received signal.  A cancellation signal is generated by the cancellation device that is substantially equal to and opposite in phase to the error portion of the receive signal.  The cancellation signals are then combined and amplitude and phase adjusted so that they have substantially the same amplitude but are 180° out of phase with the error portion.  The combined error signal is injected onto the transmission line and provided to each of the frequency tunable filters.

Inventor: BARON STANLEY C
IPC: A01F15/00
Filed: 1996-07-22
Abstract: A method and apparatus for processing a crop growing in a field by continuously cutting the crop with a transportable cutter and forming a layer of the cut crop on a moving conveyor.  A stream of solar heated air is continuously forced onto the moving crop to reduce its moisture content.  Thereafter the crop is continuously formed into bales and the bales accumulated.   The crop is much more efficiently processed by continuously cutting, solar drying, baling and accumulating it directly in the field in a one pass operation within a contained, transportable chamber.          Operator time, machine usage and fuel are conserved while weathering and collection losses are minimized.  A dessicant material aids in removing moisture from air used for drying so that dried air can be recirculated.
