Abstract: The invention concerns a method for removing sodium oxalate from the aluminate liquor from the Bayer process derived from the caustic attack of bauxite slightly loaded with organic matter (typically generating less than 400 grams of oxalic carbon per ton of alumina produced). Said method consists in treating a rather low proportion of non-concentrated spent aluminate liquor (typically 10 to 30%), by causing it to follow a circuit passing though a series of decomposition vessels-called cold mini-series- at low temperature around 40 ·C, the oxalate precipitating on part of the hydrate produced which is then recuperated after washing, in a slightly greater amount than the sampled amount. The capacity of the suspension from the cold mini-series of being filtered is remarkably enhanced by the input of an additive usually designed to promote agglomeration of fines during decomposition.

Title: Method and apparatus for fluid jet formation
Inventor: CRAIGEN STEVEN J
IPC: B26F3/00
Filed: 2000-03-08
Abstract: A method and apparatus for controlling the coherence of a high-pressure fluid jet directed toward a selected surface. In one embodiment, the coherence is controlled by manipulating a turbulence level of the fluid forming the fluid jet. The turbulence level can be manipulated upstream or downstream of a nozzle orifice (30) through which the fluid passes. For ex-ample, in one embodiment, the fluid is a first fluid and a secondary fluid is entrained with the first fluid. The resulting fluid jet, which includes both the primary and secondary fluids, can be directed toward the selected surface so as to cut, mill, roughen, peen, or otherwise treat the selected surface. The charac-teristics of the secondary fluid can be selected to either increase or decrease the coherence of the fluid jet. In other embodiments, turbulence generators (75), such as inverted conical channels, upstream orifices, protrusions and other de-vices can be positioned upstream of the nozzle orifice to control the coherence of the resulting fluid jet.

Filed: 2000-09-08
Abstract: The time required to perform communications between an entertainment apparat us (12) and a manual controller (200) having complex and sophisticated function s which is connected to the entertainment apparatus (12) is reduced. A type of  control data to be outputted from a manual controller (200) when control uni ts including direction keys are operated is defined (limited) according to an application program that is recorded in an optical disk (OD) and read by the  entertainment apparatus (12). The manual controller (200) has a setting register for setting such a type of control data. After a type of control da ta is defined in the setting register of the manual controller (200) from the entertainment apparatus (12), a CPU of the manual controller (200) transmits  only control data of the type set in the setting register for each frame of image. By thus limiting types of control data to be transmitted, the time required to perform communications between the entertainment apparatus (12) and the manual controller (200) is shortened.

Patent CA-2387418-A1 (CA)
Title: Digital vcr with non-standard speed playback
Inventor: KANEUCHI TOSHIO
IPC: G11B20/10
Filed: 1995-04-03
Abstract: A digital video cassette recorder records a high definition signal having an MPEG compatible structure, such as a proposed Grand Alliance signal. In the recorded format an advanced television frame occupies ten recorded tracks.      Reproduction at speeds other than the recorded speed is termed "Trick Play". Reproduction in a "Trick Play" mode necessitates a reproducing head crossing a plurality of recorded tracks.      However, since the advanced television signal is structured as groups of pictures comprising one interframe coded frame and a plurality of predicted frames, many of the recorded tracks contain data representing predicted frames. Thus an advanced television signal reproduced in "Trick Play" may represent a jumble of unrelated data segments. Operation in "Trick Play" may be facilitated by the selection of predetermined replay speeds and the allocation of specific locations within each track from which data may be reproduced. These specific track locations are utilized during recording to place advanced television image data for reproduction during "Trick Play" operation. The "Trick Play" image data is also reproduced during normal playback but may not be utilized. The specific track locations are selected to facilitate "Trick Play" operation at a plurality of speeds in both forward and reverse directions. Since the advanced television signal comprises a plurality of predicted frames, transition from "Trick Play" to normal speed replay requires a control function which is responsive to the reproduction, at normal replay speed, of an interframe coded frame. Various methods of reproduced image transition are disclosed for selecting both to and from "Trick Play" reproduction.

Title: Precision servo control system for a pneumatic actuator
Inventor: LIAO CHEN-FU
IPC: F15B15/08
Filed: 2000-10-27
Abstract: A precision servo control system for a pneumatic actuator has a piston (5) positionable over a stroke of the pneumatic actuator (2) using a supply of pressurized gas. A brake (52) and a sensor system (44) are connected to the actuator (2) and to the servo control system. The servo control system operates to initiate the forward thrust from the pressurized gas to move the  piston (5) along the stroke. When a braking point along the stroke is determined, the servo control system initiates a reverse thrust from the pressurized gas while maintaining the forward thrust and simultaneously begi ns to selectively apply the brake (52) to stop the piston within a predetermine d tolerance of a desired stopping position. The precision servo control system  is easily programmable in a manner similar to that of a control system for electrical actuators. The precision servo control system can maintain the predetermined tolerance even under changing loads, long stroke lengths or vertically oriented stroke directions. The precision control servo system preferably utilizes simple directional valves, instead of complex and expensive servo valves, to regulate the pressurized gas. The precision servo  control system achieves positional accuracy to a predetermined tolerance tha t is a fixed value, regardless of the stroke length.
