Title: Biomass gasification process and apparatus
Inventor: DAMMANN WILBUR A
IPC: C10L3/00
Filed: 1995-03-09
Abstract: An apparatus for a gasification of a biomass liquid solution includes a reactionchamber having a biomass liquid solution therein. The biomass solution includes at least water and carbon . A pair of spaced apart carbon electrodes are immersed in the solution within the chamber. A direct current electrical supply is connected to the electrodes to form an electrical arc passing from one electrode to the other and thereby oxidizing carbon of one electrode. The oxidized carbon forms a carbon monoxide and hydrogen gas mixture, and carbon released from the biomass solution during oxidation is deposited on the opposite electrode. A switch is interposed between the source of electric power and the electrodes so as to selectively switch the polarity of the electric arc to thereby cause oxidation of the opposite electrode and the deposit of carbon on the previously oxidized electrode while continuing to manufacture COH2 gas. A sensordetects the position of the electric arc, and thereby detects the length of the oxidizing electrode, and is electrically connected to a control unit which will cause the switch to change polarity of the electrodes when the oxidizing electrode reaches a predetermined length. The biomass solution may be formed from a mixture of water with starches, sugars, carbohydrates, alcohols, and the like.

Title: Enlarged cell foam and method of making same
Inventor: SUH KYUNG W
IPC: C08J9/00
Filed: 1993-12-07
Abstract: Disclosed is a process for making a closed-cell, alkenyl aromatic polymer foam structure having enlarged cell size. In the process, an alkenyl aromatic polymer material is heated to form a melt polymer material; a non-waxy cell size enlarging agent is incorporated into the melt polymer material; a blowing agent is incorporated into the melt polymer material at an elevated pressure to form a foamable gel; and the foamable gel is then expanded in a zone of lower pressure to form the foam structure. The enlarging agent is present in an amount sufficient to enlarge the stabilized cell size of the formed foam structure by 20 percent or more over a corresponding foam structure made without the enlarging agent. Further, the enlarging agent is incorporated in a quantity such that the formed foam structure has physical properties similar to the corresponding foam structure. Further, disclosed is a foam structure corresponding to the above.

Patent CA-2159797-A1 (CA)
Title: Compliant lens block and tape
Inventor: KO JOHN H
IPC: C09J7/38
Filed: 1995-10-03
Abstract: The present invention provides a block assembly for mounting an optical lens blank onto a lens processing machine, comprising a compliant lens block with a relatively thin double-sided adhesive tape having dirrerential adhesion. This assembly affords a very cost efficient system for attaching a lens blank to a lens processing machine. In contrast to traditional thick adhesive pads, the tapes of the present invention do not suffer from shear displacements which may cause processing errors or inaccuracies. In addition, the double-sided adhesive tapes of the present invention achieve greater adhesion to the lens block than to the lens. This feature promotes and ensures a "clean" removal of the tape from the lens when the block is deblocked. The present invention also provides a method for mounting an optical lens blank onto a lens processing machine. This method comprises the steps of: disposing a compliant block assembly in close proximity to an optical lens blank (the block assembly comprising a base structure having a compliant receiving surface adapted to conform to a surface on an optical lens blank to be processed in a lens processing machine and a mounting means for mounting the block onto a chuck of a lens processing machine, wherein at least a portion of said compliantreceiving surface is covered with a thin double-sided adhesive tape having differential adhesion); adhesively attaching the optical lens blank to the compliant block by applying the block to the optical lens blank with sufficient pressure to conform the receiving surface to the surface of the optical lens blank while theadhesive tape joins the block and optical lens blank together; and mounting the block and the adhesive tape joined optical lens blank onto the lens processing machine.

Inventor: IGWEMEZIE JUDE O
IPC: E01B9/40
Filed: 1995-11-07
Abstract: Rail fastening devices having opposing longitudinally extending shoulders to accommodate a rail flange with a downwardly facing abutment surface on each shoulder.  A resilient rail clip extends inwardly and bears upwardly on the abutment surface and resiliently on an upper side of the flange to restrain the rail against vertical movement.  An outer portion of the clip extends outwardly and curves laterally outwardly and downwardly toward a lower portio that bears on a bearing surface offset laterally inwardly from the centre of curvature of the outer portion.  This provides improved stress distribution in the clip.  A rail tie plate suitable for attachment to a wood tie, for example, has abutment members upstanding from it to accommodate a rail each with a downward facing surface to react with a rail clip, and a ramp surface that inclines from an outer side of each abutment member upwardly inwardly to an inner side to facilitate mechanized installation of the clip.

Title: Injection molding carbide torpedo
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/27
Filed: 1995-12-18
Abstract: An injection molding torpedo which can itself be injection molded by a M/M process of a carbide alloy to have high resistance to corrosion and wear. The torpedo has a conical front surface which forms a pointed tip and a melt channel extending to an outlet on the conical front surface. The melt channel has a central rear portion extending from an inlet on the surface of the torpedo and a diagonal front portion extending from the rear portion to the outlet. The diagonal front portion of the melt channel is tapered inwardly enough to offset the diagonal at which it extends to allow for free ejection of the molded torpedo from its mold. This requires that the taper be enough that the shortest longitudinal line along the inner surface forming the melt channel does not diverge outwardly anywhere along its length.

Title: Timing recovery in a network-synchronized modem
Inventor: GELBLUM EHUD ALEXANDER
IPC: H04L25/49
Filed: 1996-03-04
Abstract: A timing technique for a Quantization-Level-Sampling (QLS) modem puts timing information in a downstream pulsed signal transmitted from the public switched telephone network (PSTN) to the QLS modem. In response to this timing information, the QLS modem synchronizes to the network sampling clock in the PSTN. In particular, the pulsed signal includes data-bearing samples, which were provided by a far-end QLS modem, and at least one non-user-data-bearing (NUDB) sample in which the level of this NUDB sample periodically alternates. The QLS modem extracts timing information from this periodic alternating signal level to synchronize the QLS modem to the network sampling clock.
