Title: Cytotoxic drug therapy
Inventor: BAGSHAWE KENNETH DAWSON
IPC: A61K47/48
Filed: 1993-01-11
Granted: 2002-06-11
Abstract: A compound comprises a target cell-specific portion, such as an antibody specific to tumour cell antigens, and an inactivat-ing portion, such as an enzyme, capable of converting a substance which in its native state is able to inhibit the effect of a cytotox-ic agent into a substance which has less effect against said cytotoxic agent.  The prolonged action of a cytotoxic agent at tumour sites is therefore possible whilst protecting normal tissues from the effects of the cytotoxic agent.

Granted: 1998-01-20
Abstract: A multiprotocol transport network (MPTN) gateway provides transparent interconnection of two or more SPTNs running different transport layer protocols to form an integrated heterogeneous MPTN.  The MPTN gateway of the present invention has no dependencies on the particular transport protocols running on the SPTNs being interconnected as it utilizes a common transport provider (a GatewayServices Protocol Boundary (GSPB)) between the SPTN transport protocols and the gateway components . The MPTN gateway supports connections between end systems across multiple intermediate networks. The MPTN gateway provides automatic routing based on dynamic participation in the routing protocols of the interconnected SPTNs so that any number of gateways may be interconnected and in any topology desired. As the MPTN gateway has a general architecture and acquires routing information automatically, it supports not only other MPTN nodes and gateways but also non-MPTN nodes and gateways.

Title: Bonding material and bonding method for electric element
Inventor: KIMURA YUJI
IPC: H01S5/042
Filed: 1995-07-31
Granted: 2003-03-25
Abstract: A material and method for bonding a semiconductor device to a pedestal, which can obtain satisfactory bonding strength and stable electric contact, are disclosed. On an n-type electrode constituting an ohmic electrode for a semiconductor laser device are formed a N1 layer and an Au-Sn solder layer. Then, the solder layer is melted and bonded to a heat sink provided with Au-plating. The film thickness of the N1 layer is set to approximately 500.ANG. or more. When the solder layer is melted, N1 in the N1 layer diffuses into the solder layer and Sn in the solder layer diffuses into the N1 layer. By this mutual diffusion, bonding strength and wettability between the semiconductor device and pedestal are improved. In addition, by setting the composition ratio of the N1 layer to the Au-Sn solder layer to between about l.3wt% and about lOwt%, the melting point of the mixed alloy is lower, and bonding can be carried out at lower temperatures.        Concurrently, a higher bonding strength can be obtained.

Abstract: L'invention se rapporte à un procédé de fabrication d'un article absorbant (144). Au cours de ce procédé, la vitesse d'une partie (7b) d'une bande (1) à défilement continu comportant une feuille supérieure (121), une feuille inférieure (123), une âme (120) ou tout autre agencement, varie périodiquement, alors qu'une vitesse constante des parties amont (3) et aval (5) de la bande (1) et maintenue. Le procédé consiste à faire passer la bande (1) devant des cylindres de transport rotatifs (13, 15) qui oscillent parallèlement à la bande (1) dans le sens du transport (F) et dans le sens opposé au transport (F). Trois sections (7a, 7b, 7c) de la bande, lors de l'oscillation des cylindres de transport (13, 15), sont maintenues parallèles les unes par rapport aux autres. Un dispositif d'équilibrage du mouvement de translation (77) et des dispositifs d'équilibrage (63, 63') de la rotation permettent l'entraînement des cylindres de transport (13, 15) à des vitesses élevées et à de faibles variations du couple. La contrainte exercée sur la bande (1) reste relativement faible et est limitée aux forces d'inertie qui agissent sur la bande (1).

Granted: 2008-08-12
Abstract: The invention provides a method of replacing the wheels of a railroad car while the railroad car is at rest on rail tracks. Most advantageously, the rail car need not be uncoupled from adjacent cars. The method also has the advantage that rail cars are jacked at the coupler thereby making the method applicable to all types of cars including grain and oil cars which cannot be jacked in their midsections. The method comprises the steps of: releasing the wheel to be replaced from the rail car; transverse insertion of a jack between the rails and the underside of the coupler; actuating the jack to lift the rail car supported upon the underside of the coupler; removing the wheel to be replaced; replacing the wheel; actuating the jack to lower the rail car onto the replaced wheel; securing the replaced wheel to the rail car. The invention also provides a jack for raising and lowering an end of a railroad car having a coupler extending therefrom, the railroad car being at rest on longitudinal rail tracks, the jack being disposed between the rails and the underside of a coupler, the jack comprising: a base supported upon the rails; a cap disposed in parallel above the base; coupler support means for supporting the rail car coupler upon the cap; and lifting means, disposed between the base and cap, for selectively raising and lowering the cap relative to the base between a collapsed position wherein the jack is clear of the rail car to facilitate transverse insertion between the rails and the underside of the coupler, and a maximum lift extended position. Advantageously the coupler support means comprise a travelling table means for shifting the coupler transversely thereby aligning the rail car wheel flanges on the rail head.

Abstract: This invention relates to the use of a eukaryotic or prokaryotic DNA- directed RNA polymerase of a class that synthesizes cellular RNA, in a process for the amplification of a specific nucleic acid sequence or of its complement. It also relates to a new process for amplifying a specific nucleic acid sequence. The process includes one or more reactions which may take place in a single reaction vessel. In one instance, in a first reaction, the process includes providing a first RNA polymerase which uses a DNA first template to synthesize an RNA first template, and, in a second reaction, providing the RNA first template and a number of other reagents such that the reagents use the RNA first template to synthesize a DNA second template and an RNA second template. Thereafter a cycle ensues in which the reagents use the RNA second template to synthesize a DNA third template and multiple copies of the RNA second template. The RNA second template is the specific nucleic acid sequence or its complement. This invention includes a kit containing the reagents of this invention.
