Title: High productivity, continuous fermentation process for carotenoid-producing microorganisms
Inventor: BAILEY RICHARD B
IPC: C12P23/00
Filed: 1991-05-14
Abstract: A high productivity method for efficiently fermenting heterotrophic algae. The method includes diluting the fermentation broth.  Additionally, a carbon source for the growth of the microorganisms is limited in a manner designed to restrict the growth rate to a level less than the maximum rate. The method is especially useful in the fermentation of Neospongiococcum algae. In preferred embodiments, the temperature of the fermentation broth is maintained from 30 ·C to about 38 ·C and the pH of the fermentation broth is maintained from about pH 5.5 to about pH 6.5. Using this method, volumetric productivity has been increased to at least about 20 mg total xanthophylls per liter per hour.

Patent CA-2098987-A1 (CA)
Inventor: HARPER JOHN
IPC: H04L45/28
Filed: 1992-01-08
Abstract: A technique for logically connecting local area networks (LANs) that may be separated by wide area networks containing routers and other network components. A logical link is formed between two bridge-like devices called tunnelers, such that, once a tunnel has been established between two LANs, other devices on the LANs can communicate as if the tunnel were a bridge. The tunneling mechanism of the invention requires that each LAN or extended LAN have only one active tunneler at any particular time, referred to      as the designated tunneler, and each of the tunnelers is configured to have knowledge of the identities of the other tunnelers. A tunnel is established after a successful exchange of messages between two tunnelers, and then traffic may be forwarded through the tunnel in a transparent manner. The tunneling mechanism permits messages to be forwarded between LANs separated by a wide area network containing routers. Moreover, the mechanism permits filtering of traffic, such that only selected types of traffic, or messages for selected destinations or from selected sources, are forwarded through tunnels. The tunneling mechanism inherently precludes the formation of closed communication loops. An alternate embodiment of the invention optimizes the configuration process for particular network topologies.

Abstract: A mechanism for mounting an axle to a vehicle, and including a power output shaft drivingly coupled with a generally cylindrical coupler which is drivingly coupled with a first sleeve.  A first axle is coupled for rotation with the first sleeve, and a first ground engaging wheel is coupled for rotation with the first axle and is thereby operatively driven by the output shaft.  A first axle housing rotatably supporting the first axle is generally rigidly and releasably fixed to the frame of the vehicle.  A first sprocket is fixed for rotation with the first sleeve, and a chain operatively extends between the first sprocket and a second sprocket which is fixed for rotation with a second sleeve.  The second sleeve is operatively coupled with a second axle rotatably supported by a second axle housing, and therefore a second ground engaging wheel is driven with the first ground engaging wheel. An adjustable tensioning mechanism includes a bolt and nut for shifting the second axle housing with respect to the first axle housing to thereby adjust the tension in the chain.

Abstract: A stuffed mailing envelope is formed from webs of paper. A plurality of insert sheets are constructed from webs of insert paper by variably imaging the insert webs, and then intelligently aligning them and cutting them into aligned sheets, and then folding the aligned sheets to produce a formed insert. A plurality of interconnected envelope blanks are formed from an envelope web of paper, and a plurality of insert sheets (including the formed insert) are collected and placed on each of the envelope blanks while they are interconnected in web form. Then, while conveying the interconnected envelope blanks in web form, the blanks are severed from each other and are formed around the inserts to produce a final mailing envelope containing a plurality of insert sheets. The envelope blank typically has two parallel minor flaps and two parallel major flaps. The envelope is formed by sequentially plough folding over the minor flaps, severing the leading interconnected blank from the next blank so that the major flaps are free, changing the direction of conveyance, applying adhesive to the major flaps, and plough folding the major flaps so that the adhesive comes into contact with the minor flaps and the other major flap.

Abstract: In a switching system, a data bus which interconnects circuit modules, a switching network module and a control module for transporting packets between the interconnected modules. A bus interface (16) is connected to the data bus (13) for receiving a copy of every packet on the data bus. An error detector (18) determines whether the received packet contains an error, and produces an error detect signal and an error check result if the received packet is determined as having an error. In response to the error detect signal, the received packet, the error check result and time-of-day data are stored into a register (19) and transferred to one of the storage locations of a memory (20) to keep a list of error records. A maintenance station (22) reads stored error records from the memory for identifying the source of errors.

Abstract: A method of electronically measuring parameters of an beam in a raster scan system includes the steps of, choosing a predetermined pixel to be calibrated, moving a grid adjacent this pixel, strobing the beam, incrementally moving the beam toward an axis of the grid, and integrating the signal resulting from the beam as the beam moves toward the axis. The steps of strobing the beam, incrementally moving the beam, and integrating the signal are repeated until the beam crosses the axis. The value of the accumulated signals, provided for example by a charge amplifier, is used to determine the relative position of the axis of the grid. The value of the accumulated signals associated with another axis is also determined. The relative positions of the two axes determine the relative location of the grid. If the grid location is known, the location of an associated substrate which is typically adjacent the grid is also known.

Abstract: When printing images as ordinary prints on a photosensitive material, index prints are also automatically printed of a same size as the ordinary prints for higher work efficiency.  At a projection exposure stage, exposure of a film is effected to obtain ordinary prints using a light source, a lens and a shutter.  Also data of images on the film is read by an optical reader and converted into digital signals.  Index prints are then exposed by a PLZT print head which is controlled based on the digital signals.
