Title: Cleaning and finishing a ceramic mold
Inventor: CIMA MICHAEL J
IPC: B29C33/56
Filed: 1993-11-22
Granted: 2006-11-21
Abstract: A technique for removing loose powder from the interior surfaces of a ceramic mold made using layer manufacturing processes, such as three-dimensional printing processes. The interior of a mold can be filled with water which is boiled and the particles are entrained in the flow caused by the boiling liquid. Alternatively, fine particles are introduced into the mold and agitated in the mold to dislodge the particles and the powder so that they can be poured out of the mold. Such technique tends also to remove the surface finish of the mold. Any of the particles which remain can be dissolved in a liquid and removed in the liquid from the mold. Further, the surface finish of the mold can be improved by casting a slip of fine particles on to the surface to form a generally level, and preferably non-conformal, coating on the surfaces.

Abstract: A novel isolated Borrielia burgdorferi sensu lato surface antigen is characterized by a relative molecular mass of 39.5 kDa. This antigen is expressed in vitro by spirochetes of a B. burgdorferi sensu lato strain. This antigen induces antibodies which kill spirochetes of a B. burgdorferi sensu lato strain by ADCK in vitro. Novel Borrelia cassette string protein or fragments thereof are also useful, as is the P39.5 protein in diagnosing Lyme disease and in compositions for treatment o r prophylaxis thereof.

Abstract: Tat-inhibitory oligocarbamate derivatives of the formula I (see formula I) and analogs thereof, and the biologically and pharmaceutically acceptable salts thereof exhibit advantageous properties, including specific binding to TAR RNA with high affinities, and stability of the resultant oligocarbamate-RNA complexes to proteolytic digestion. Site-specific photocrosslinking experiments using a photoactive analog (4- thio-uracil) containing TAR RNA indicate that these oligocarbamates interact with RNA in the major groove. These oligocarbamates are thus capable of competing with the TAR RNA-binding domain of Tat protein and thus are useful as a therapeut ic agents in the treatment of AIDS.

Abstract: A rotatable connection system for boom sections has been invented. With the invention, boom sections can be added to a boom being constructed in either a horizontal layout configuration or in a vertical configuration, such as adding a boom section onto a hanging luffing jib boom butt. With the invention, a horizontally orientated boom section can be added to a hanging boom. The coupler of the female connection is placed in the socket of the male connector and the retainer is put in place to keep the male and female connectors coupled. The assembly is then boomed up, the weight of the new section being carried by the coupler. The new section is free to rotate until it also is hanging nearly vertically. The section is then swung into an aligned position and lower connector pins can be inserted to secure the bottom connectors. This method of adding sections and booming up is continued until the desired luffing jib boom length is assembled.

Title: Dual band direct conversion receiver
Inventor: MCKINNEY JOHN K
IPC: H04B1/38
Filed: 2000-04-26
Granted: 2005-10-18
Abstract: A receiver (100) provides dual band features by providing two signal paths (106, 108) off an antenna (102), one for UHF operation (106) and one for VHF operation (108). The two signals paths (106, 108) feed into a single broadband input (124) of a direct conversion receiver (114). The UHF path (106) utilizes UHF front end circuitry (110) while the VHF path (108) is implemented with a loading/isolator circuit (120) and a matching circuit (122). The loading/isolator circuit (120) loads the antenna (102) and isolates UHF signals while the matching circuit (122) provides a match between the loading isolator circuit (120) an the direct conversion receiver (114). Selectable matching circuitry (126, 128) and selectable VCO circuitry (132, 134) configures the direct conversion receiver for the UHF or VHF mode of operation.

Abstract: A method and an apparatus for optimizing the combustion air system in a power boiler or chemical recovery boiler by improving fluid flow and gas mixing are disclosed, whereby one can increase boiler capacity and combustion uniformity and reduce particulate and gaseous emissions. The method involves interlacing of the secondary and, where applicable, the tertiary air supply through opposing air ports on all four walls of the boiler, and is implemented by alternately opening wide or partially closing a port damper on one side, while partially closing or opening wide a port damper on the opposite side, such that a 70-100% open damper on one side opposes a partially closed (10-40% open) damper on the other and vice versa in an alternating fashion, along opposing walls. In a preferred embodiment, the optimization is further enhanced by balancing primary air flow, achieved by adjusting port dampers and windbox pressures so that the primary air flow is evenly distributed between opposite walls, between all four walls of the boiler and between individual airports on each wall. Windbox pressure and other key measurements of boiler operation ensure proper balancing and an adequate interlacing of air flows at the primary, secondary and tertiary elevations, respectively.

Abstract: Ce système permet d'augmenter la capacité d'un réseau AMCR comprenant plusieurs sites de cellules (4110, 4120, 4130) et consiste à définir un groupe de fréquences (F1, F2) disponibles et à attribuer une de ces fréquences disponibles (F1, F2) à chacun des sites de cellule (4110, 4120, 4130), de manière à minimiser le nombre de sites voisins auxquels une même fréquence disponible (F1, F2) est attribuée. En déployant différentes fréquences (F1, F2) dans les sites de cellules (4110, 4120, 4130), on réduit la quantité d'interférences provoquées par les sites voisins, ce qui permet alors d'augmenter la capacité de chaque site (4110, 4120, 4130) fonctionnant selon une seule fréquence (F1 ou F2), pour autant qu'il reste une puissance suffisante pour atteindre les unités mobiles (4200) fonctionnant dans le site (4110, 4120, 4130). Ce système permet d'obtenir des bénéfices maximaux lorsque les sites de cellules (4110, 4120, 4130) sont situés à proximité les uns des autres et que l'exposant de propagation est faible (par exemple 10-20 dB/décade)

Abstract: Described herein is a method for reassembling variable length packets from fixed length cells. When a variable length packet, for example, an Internet Protocol (IP) packet, is transmitted between routers over a link which transmits data as fixed length cells, for example, an asynchronous transfer mode (ATM) link, the packet must be segmented into compatible fixed length cells. The receiving router must reassemble the original packet from the cells as they arrive. A packet buffer free pool (300) is provided which is maintained as a linked list, known as a 'free list', and which comprises a plurality of buffer elements (302, 304, 306, 308, 310, 312, 314, 316, 318, 320, 322, 324, 326, 328, 330, 332, 334, 336, 338, 340). When a first cell for a given packet arrives, a buffer element (302) is taken from the head of the free list and allocated to that packet. The packet data from the first and subsequent cells is copied into the allocated buffer element and each time the buffer element is moved to the end of the free list. Upon the arrival of the last cell for the given packet, the complete packet is processed. Failed reassemblies are automatically abandoned as the buffer element is reused when it reaches the head of the free list. This technique is relevant to protection against "denial of service" attacks upon computer networks.
