Title: Angle joint
Inventor: RAAK MARTIN
IPC: F16C11/06
Filed: 2002-04-23
Abstract: The invention relates to an angle joint for the articulated connection of two components. Said joint comprises a ball, to which a first fixing element for fixing the ball to a first component is attached, and a ball socket, which at least partially surrounds the ball and has a second fixing element for fixing a second component. The fixing element that is attached to the ball can be rotated about a preferred axis at least within an angular range and pivoted in relation to the second fixing element. The aim of the invention is to produce an angle joint, in which the ball can be mounted easily and securely into the ball socket and which is easy to produce. To achieve this, the invention is provided with a lining part (8) that can be positioned in the ball socket (6) and that has a receiving area (15) for the ball (2), whereby the lining part (8) has at least one sliding surface (23) for bearing the ball (2) in a sliding manner and the lining part (8) is provided with positive-fit elements (25) that are formed thereon in one piece for securing said part in the ball socket (6) and with positive-fit elements (21) that are formed thereon in one piece for securing the ball (2) inside the connecting part (8). The fixing elements for fixing the ball (2) inside the lining part (8) can be configured as self-locking elements.

IPC: H04L12/56
Filed: 2002-07-12
Abstract: A one-to-many wireless telephone communication system includes a transmitting telephone that transmits voice packets in, e.g., CDMA to a base station in an IP-based infrastructure. The base station converts the CDMA packets to IP and sends them through the infrastructure to a communication manager, which copies the packets as many times as necessary for the recipient telephones in the group and sends the IP packets back through the infrastructure using the IP  addresses of the recipients. The base stations receiving the IP packets transform them to voice packets and transmit the voice packets to the recipient telephones, thereby relieving the telephones from having to support IP.

Title: Systeme d'administration de medicament par voie transdermique, a base de strychnine, brucine, securinine et de leurs sels
Inventor: ZHANG XITIAN
IPC: A61K9/70
Filed: 2002-10-18
Abstract: La strychnine, la brucine (A) et la sécurinine (B) constituent un groupe de médicaments naturels pour l'excitation centrale. Etant donnée que leur dose orale ou leur dose injectable est proche de la moitié de la dose léthale, les médicaments, qui possèdent des effets secondaires très toxiques, peuvent être mortels s'ils sont mal utilisés. L'invention concerne l'utilisation d'un système d'administration de médicament en tant que substitut à la forme posologique orale ou injectable, pour une action directe sur le système nerveux local à travers la peau, et la suppression simultanée des effets secondaires toxiques touchant directement le système circulatoire. La dose destinée à être administrée par absorption cutanée est nettement inférieure à celle administrée par voie orale ou par injection, si bien qu'elle est nettement plus sûre et qu'elle n'a pas d'effet durable. Le système d'administration de médicament par voie transdermique est utile pour le traitement de la paralysie induite par le système nerveux central ou périphérique et d'autres affections relatives au système nerveux.

Title: Use of tgf-.beta. antagonists to treat or to prevent chronic transplant rejection
Inventor: LIU MINGYAO
IPC: C07K14/71
Filed: 2003-01-21
Abstract: Effective use of a TGF-.beta. antagonist to treat or to prevent loss of transplant function is described herein. Use of a TGF-.beta. antagonist is demonstrated to effectively prevent loss of organ function in a host due to chronic rejection in which TGF-.beta.-mediated fibroproliferation is a characteristic. Expression in situ of a TGF-.beta. antagonist in the form of a recombinant receptor, i.e., TGF-.beta. type III receptor (TGFBIIIR) showed prevention of bronchiolitis obliterans in comparison to untreated controls in a rat lung transplant model. This provides an effective method for preventing or inhibiting chronic rejection of transplant organs such as lung, kidney, liver and hear in vertebrate hosts including human hosts.

Patent CA-2476956-A1 (CA)
Inventor: ASHDOWN MARTIN LEONARD
IPC: A61P31/14
Filed: 2003-02-18
Abstract: The present inventor has noted that at least two populations of immune cells are produced in response to retroviruses which infect mammals. More particularly, the immune system of a mammal infected with a retrovirus is capable of mounting an immune response against the virus through a group of cells herein generally referred to as "effector cells", however, a second population of cells are also produced which regulate the "effector cells", herein generally referred to as "regulator cells" (or suppressor cells), limiting the mammal's ability to effectively control or eradicate the retroviral infection. Accordingly, the present invention utilizes these observations to provide methods for treating a mammal with a retroviral infection. Furthermore, the present inventor has found that acute phase inflammatory markers can be used to detect and monitor an"effector cell" response to retroviral antigens.

Inventor: MONTGOMERY JAMES P
IPC: H01Q23/00
Filed: 2003-03-17
Abstract: Passive intermodulation interference control circuits constructed from distributed elements of defined length and impedance segments of transmissio n media. The distributed elements can be combined with conventional discrete elements, such as resistors, to create a passive circuit that can be tuned t o have a desired frequency response by selecting the size, length and position of the distributed elements. That is, the complete PIM interference control circuit is typically constructed from a combination of discrete and distributed elements and directly connected to or within the transmission media carrying the analog electromagnetic energy through a continuous extension of the transmission media. As such, the PIM interference control circuit can be located very close to the source of the PIM interference, suc h as the antenna's power divider. When strategically located in this positionk , the PIM circuit controls the intermodulation interference right at the sourc e, before it enters the electronics of the receiver.
