Title: Carbothermic reaction process for making nanophase wc-co powders
Inventor: MCCANDLISH LARRY E
IPC: C01B32/949
Filed: 1992-08-06
Abstract: A new carbothermic reaction process is described for the thermochemical processing of nanophase WC-Co powders. The process permits shorter reaction times, reduced temperatures, and finer microstructures compared to conventional processing methods. The process builds on our experience with spray conversion processing [1], but involves 1) chemical vapor infiltration reaction of the carbon infiltrant and particle substrate to form WC-Co; and 2) removal of any excess (unreacted) carbon by con-trolled gasification. A feature of the carbothermic reaction process is its adaptability to conventional WC-Co processing technolo-gy, as well as to spray conversion processing technology. The resulting powder particles consist of a network of fine grains, (less than 100 nm) of WC and Co with interconnected fine porosity. Powder particles suitable for subsequent handling and consolida-tion are readily produced with diameters greater than 10 microns.

Title: Antitumor vaccines
Inventor: SPITLER LYNN E
IPC: A61K9/127
Filed: 1992-11-25
Abstract: Tumor-associated antigens which caracterize tumors of given histologic types are exemplified by CO-029, which is asso-ciated with tumors of the gastrointestinal tract, colorectum and pancreas, and by GA-733-2, which is associated with tumors of the gastrointestinal tract, prostate, cervix, ovary, bladder, lung, breast, colorectum and pancreas. These antigens, which are broad-ly shared by these tumors, can be synthetically prepared, independent of the tumor itself. These independently prepared antigens are useful as active ingredients in compositions which provide therapeutic protocols to subjects that harbor such tumors or are at risk from such tumors. The vaccine compositions of the invention have enhanced antigenicity by virtue of encapsulation of these antigens in liposomes or covalent coupling of the antigens with liposomes.

Title: Method and apparatus for automatic gain control and dc offset cancellation in quadrature receiver
Inventor: WILSON NATHANIEL B
IPC: H03D3/00
Filed: 1995-04-28
Abstract: An automatic gain control (AGC) and D.C. offset correction method and apparatus for controlling signal power of a received RF signal within a dual mode quadrature receiver is disclosed herein. The AGC apparatus includes an adjustable gain amplifier (18). A quadrature downconverter (20) coupled to the amplifier (18) serves to translate the frequency of the output signal to a baseband frequency which is offset by a predetermined margin from D.C. Two high gain active lowpass filters (76 and 78) provide out-of-band signal rejection for the baseband signals. A D.C. feedthrough suppression loop supresses D.C. offsets produced by a downconverter (20) and the lowpass filters (76 and 78). The AGC apparatus also generates a received power signal based on the power of the output signal. A saturating integrator compares the received power signal to a reference signal and produces the gain control signal by integrating or by refraining from integration based on values of the reference, received power signal, and gain control signals.

Title: Annular Mask Contact Lenses
Inventor: MILLER DAVID
IPC: G02C7/04
Filed: 1994-09-13
Abstract: An annular mask contact lens (10) designed to operate with the normal functioning of the human pupil.  An annular mask (18) forms a small pinhole-like aperture (20) on the contact lens (10) enabling continual focus correction.  The outer diameter of the annular mask (18) allows the wearer to transmit more light energy through the pupil as brightness  levels decrease.  The contact lens (10) may be structured with two separate and distinct optical corrections, both at the small aperture region and in the region beyond the annular mask.  Functional imaging is thus achieved for both bright and dim lighting, and over a wide range of viewing distances.  Cosmetic and peripheral vision enhancement is also provided by the contact lens constructed according to the invention.
