Title: Inflatable support
Inventor: TEASDALE BARRY CHARLES
IPC: A47C27/18
Filed: 1998-05-19
Abstract: An inflatable support (e.g. a mattress or seat cushion) comprises a plurality of elongate inflatable cells (12) containing a solid deformable material such as resilient foam, beads or fibres. Typically, the cells are inflated and deflated periodically by means of a pump (P). The solid within the cells reduces the volume of air within the cells, and thus a pressure pump of a lower rating for supplying pressurised air can be used.          Moreover, if the supply of pressurised air should fail for any reason a patient on the mattress will still be supported by the deformable material within the cell.

Title: Electrically-operated injection molding machine and injection molding method using the relevant machine
Inventor: TANIGUCHI YOSHIYA
IPC: B29C45/77
Filed: 1998-07-06
Abstract: An apparatus has servo motors used for driving sources in processes of weighing blended resin, of injecting weighed resin into a die cavity, of opening and closing dies, of gate cutting after filling weighed resin into the die cavity, of ejecting the molding after forming, and of removing the molding.    According to this configuration, because all the motions of injection operation are controlled by servo motors, the timing, injection speed, pressurizing speed, pressurizing pressure, and all others can be freely controlled, and not only the transferability of fine protrusions and recessions formed on the inner surface of the die cavity can be remarkably improved, but also the cycles can be increased because complex motions can be carried out by servo motors.     In particular, because servo motors are used for driving sources of ejection of molding after forming and removal of molding, there is no variation in repetitive response accuracy in motion, product removal timing by the product removing equipment can be reduced to 0.01 second or less, and ultimately higher cycle is able to be achieved.

Title: Video data editing apparatus and computer-readable recording medium storing an editing program
Inventor: NAKATANI TOKUO
IPC: G11B27/10
Filed: 1998-09-17
Abstract: During video editing, video data is recorded in continuous areas of at least a predetermined length on an optical disc to ensure that the display of video images is uninterrupted. A first segment, out of a plurality of segments recorded on an optical disc, whose consecutive area on the optical disc is shorter than the predetermined length is detected. Re-encoded data that is to be reproduced either immediately before or immediately after the detected first segment is recorded next to the first segment. If the combined continuous area of the first segment and the re-encoded data is still below a predetermined length, the segment that is to be reproduced on the other side of the re-encoded data to the first segment is recorded on the optical disc so as to be positioned on the other side of the re-encoded data, thereby increasing the continuous length of the recording area beyond the predetermined length.

Abstract: A process for recovering quantities of carbonyl compound material from spent solvent-in-water emulsions derived from paint overspray treatment and capture systems in which the spent solvent-in-water emulsion is removed from the paint overspray treatment and capture system and fed into a reaction vessel. The reaction vessel employed includes an outer housing defining a reaction chamber and a plurality of mixing blades movably positioned in the reaction chamber.  The surface area of the mixing blades are maintained at a temperature sufficient to generate volatilized carbonyl compound. The interior of the reaction vessel is maintained under a vacuum. The spent solvent-in-water emulsion is processed in the reaction vessel for an interval sufficient to generate volatilized carbonyl compound. The generated volatilized carbonyl compound material is removed from the reaction vessel for recycle and reuse and the residual solid material remaining in the reaction vessel after generation of the volatilized carbonyl compound material is removed. The spent solvent-in-water emulsion which can be treated by the solvent recovery process of the present invention contains carbonyl compounds selected from the group consisting of secondary alcohol esters, secondary alcohol ester derivatives, and mixtures thereof and has a boiling point of at least 150 ~C, a vapor pressure between about 0.5 Torr at 20 ~C. The spent solvent-in-water emulsion processed by the carbonyl recovery method can either be previously dewatered to produce a spent solvent-in-water emulsion material with little or no water remaining or can be processed with most or all of the water portion of the emulsion present. In such instances, the water portion may be con-generated with the carbonyl compound.

Abstract: An air supported conveyor,  particularly adapted for conveying articles such as baggage or packages at a high rate of speed includes a plenum chamber and a belt support containing  a  plurality  of  orifices.    Air  or  another pressurized  fluid is  supplied to the plenum chamber  to provide a clearance or air bearing between the belt and the support  during  belt  travel.    The  belt  support  has  a generally  flat  center  section  with  outer  sections  that curve or angle upwardly.   Guides are mounted adjacent the angled outer sections.   Disposed along the length of the belt and between an underside of each guide and the angled outer belt sections are elongated members.  Each elongated member in conjunction with each guide underside and belt support acts as a belt edge guide by forming a recess which receives the belt edges during belt travel.   Each recess directs air from the belt underside up and around the belt side edge, across the upper surface of the belt and out a slot egress.   The recess assists in creating a pressure against  the  upper  surface  of  the  belt  in  the  guide underside vicinity, thereby minimizing or eliminating belt contact with the guide underside and potential belt wear or damage with high speed belt travel.

Title: Production of synthesis gas by mixed conducting membranes
Inventor: NATARAJ SHANKAR
IPC: C01B13/02
Filed: 1998-12-16
Abstract: Hydrocarbon feedstocks are converted into synthesis gas in a two-stage process comprising an initial steam reforming step followed by final conversion to synthesis gas in a mixed conducting membrane reactor. The steam reforming step converts a portion of the methane into synthesis gas and converts essentially all of the hydrocarbons heavier than methane into methane, hydrogen, and carbon oxides. The steam reforming step produces an intermediate feed stream containing methane, hydrogen, carbon oxides, and steam which can be processed without operating problems in a mixed conducting membrane reactor. The steam reforming and mixed conducting membrane reactors can be heat-integrated for maximum operating efficiency and produce synthesis gas with compositions suitable for a variety of final products.
