Title: Compounds and pharmaceutical compositions for the treatment and prophylaxis of bacterial infections
Inventor: HULTGREN SCOTT
IPC: A61P31/04
Filed: 1994-11-18
Abstract: Novel methods for the treatment and/or prophylaxis of diseases caused by tissue-adhering bacteria are disclosed. By interacting with periplasmic molecular chaperones it is achieved that the assembly of pili is prevented or inhibited and thereby the infectivity of the bacteria is diminished. Also disclosed are methods for screening for drugs as well as methods for the de novo design of such drugs, methods which rely on novel computer drug modelling methods involving an approximative calculation of binding free energy between macromolecules. Finally, novel pyranosides which are believed to be capable of interacting with periplasmic molecular chaperones are also disclosed.

Title: Device for transmission of one-way torque
Inventor: HODSON PETER DAVID
IPC: A61M15/00
Filed: 1994-11-21
Abstract: A device for the transmission of one-way torque comprising an outer annular  member (2) having a plurality of radially inwardly projecting teeth (4) each comprising a driving surface (6) and a cam surface (8),  and a shaft (10) concentrically mounted with respect to the outer annular member (2) and comprising a plurality of drive elements (16) each having a driving surface (18) and a cam surface (22).  Rotation of the shaft (10) or outer annular member (2) in its driving direction causes engagement  of a driving surface of at least one drive element  with a driving surface of at least one tooth thereby resulting in joint rotation of the shaft (10) and outer annular member (2). Rotation of the shaft (10) or outer annular member in its non-driving direction causes engagement of the cam surface of at least one drive element with the cam surface of at least one tooth (4) resulting in additional relative movement, substantially radially between the drive element and tooth, thereby preventing rotational movement being transmitted between the shaft (10) and the outer annular member (2).

Patent CA-2197339-A1 (CA)
Title: A gripping device
Inventor: KIRK IAN ALISTAIR
IPC: F16B7/14
Filed: 1995-08-10
Abstract: A gripping device is described which has an inner member and an outer member.  The inner member has a split which define a first end and a second end. A selectively operable device is also included to keep the first and second ends apart to permit the device to be placed around an object and to permit the first and second ends to move toward each other so that the inner member grips the object. At least part of an outer face of the inner member interfits with at least a part of an inner face of the outer member in a manner such that when a load is applied to the outer member, the inner face of the outer member acts upon the inner member to cause compression of the inner member thereby increasing the grip of the inner member on the object. The device is then locked in position on the object and when the load is removed the action of the outer member on the inner member is reduced thereby decreasing the grip of the inner member on the object and unlocking the device from the object.
