Patent CA-2160993-A1 (CA)
Inventor: DESHPANDE RAVINDRA
IPC: C01B33/16
Filed: 1994-04-28
Abstract: This invention provides an extremely porous xerogel dried at vacuum to below-supercritical pressures but having the properties of aerogels which are typically dried at supercritical pressures. This is done by reacting the internal pore surface of the wet gel (e.g. alkoxide-derived silica gel) with an organic surface modification agent (e.g. trimethychloro-silane in benzene) in order to change the contact angle of the fluid meniscus in the pores during drying. Shrinkage of the gel (which is normally prevented by the use of high autoclave pressures, such that the pore fluid is at temperature and pressure above its critical value) is avoided even at vacuum or ambient pressures. The figure 4 shows a change in sample weight and sample length during drying for surface modified, ambient pressure gel processed in accordance with the invention, illustrating the initial shrinkage followed by expansion of the gel during the final stages of drying. The extremely low density finely pored gel products have useful insulating and other properties.

Title: Monogenous preparations of cytotoxic conjugates
Inventor: SOSNOWSKI BARBARA A
IPC: C12N15/09
Filed: 1994-07-27
Abstract: Monogenous preparations of conjugates of fibroblast growth factors (FGF) with cytotoxic agents are provided. Substantially all of the cytotoxic conjugates in the resulting monogenous preparation contain the same molar ratio of cytotoxic agent to polypeptide reactive with an FGF receptor. The conjugates are produced by chemical conjugation and also by expression of DNA encoding the conjugate to produce fusion proteins. The chemical conjugates are prepared by reacting FGF, which has at least one of the reactive cysteines replaced or deleted, with purified mono-derivatized saporin or with saporin that has been modified at or near one terminus by addition of a cysteine residue or replacement of a residue with cysteine. The resulting preparations are substantially monogenous. Fusion proteins are produced by expressing DNA constructs encoding muteins of an FGF in which one or more of any reactive cysteines have been deleted or replaced linked to DNA encoding a cytotoxic agent are also provided. The DNA constructs are expressed in host cells to produce monogenous preparations of cytotoxic FGF, conjugates. In embodiments in which the FGF portion of the conjugate has been modified so that there are no cysteines available for reaction, the resulting compositions are free of aggregates. The monogenous preparations of conjugates provided herein are potent cytocidal agent to cells bearing the FGF receptor.

Title: Automatic exposure single frame imaging systems
Inventor: WANG YNJIUN P
IPC: G06K7/10
Filed: 1995-07-26
Abstract: An automatic exposure imaging system (Fig. 2) operating on a single frame image capture basis is adapted for single chip CMOS type construction. For reading dataforms, such as two-dimensional bar codes and matrix codes, the system can provide automatic gain control (60), automatic exposure control (64), automatic focus sensing (62) and single frame imaging and decoding, with reduced power consumption.  A fixed focus distance sensor element array assembly (21b) and optical distance sensing enable automatic initiation of exposure when the image is in-focus (Fig. 4). Exposure provided by image illuminators (50, 54) is automatically controlled by sensing of the cumulative level of reflected light during the exposure period (Fig. 6). Alternatively, exposure time is determined from a look-up table (82a), based upon the level of light reflected during an initial illumination period of fixed duration (Fig. 7). Automatic system turn-off or re-reading can be provided, depending upon whether a dataform is successfully decoded (Fig. 6 and 7). Power use is reduced by terminating the reading of sensor elements upon successful decoding. A complete, light-weight, hand-held reader (10) is described, including provison for transmission of decoded dataform information and a wide range of additional capabilities via plug-in cards (34, 36). Related methods are also described.

Patent CA-2182374-A1 (CA)
Title: Variable referenced control system for remotely operated vehicles
Inventor: THORNBERG CHRISTOPHER ALLEN
IPC: G05D1/00
Filed: 1995-02-22
Abstract: A frame of reference is selected, and con-trol inputs provided by a vehicle operator are trans-formed to account for the orientation of a remotely operated vehicle with respect to the selected frame of reference such that the remotely operated vehi-cle responds to the control inputs with respect to the selected frame of reference. An earth frame of refer-ence may be selected based on a fixed true heading, e.g., North, or based on the initial orientation of the vehicle operator. Alternatively, a vehicle frame of reference may be selected which provides a fixed frame of reference with respect to the vehicle and a variable frame of reference with respect to the vehi-cle operator. A vehicle operator frame of reference may also be selected based on the orientation of the vehicle operator with respect to earth, and control commands are transformed based on changes in both the operator orientation with respect to the earth ref-erence and the remotely operated vehicle orientation with respect to the earth reference, which provides a fixed frame of reference with respect to the vehicle operator and a variable frame of reference with re-spect to the vehicle. The remotely operated vehicle heading transformation may be based on a selected forward, fixed or variable point on the vehicle re-lated to a vehicle center of gravity a forward part of the vehicle, the location of a sensor on the ve-hicle, or some other arbitrary reference location on the vehicle.
