Title: Esters of castanospermine in the treatment of cerebral malaria
IPC: A61P33/02
Filed: 1990-10-16
Abstract: Red blood cells which are infected with the parasite P. falciparum cause the cells to become sticky and less deformable. This results in a build-up of cells on the vascular wall and creates occulsions to blood flow which are thought to cause the cerebral, renal and liver complications of P. falciparum infections. Certain esters of castanospermine prevent or reduce the adhesion of falciparum infected blood cells to the vascular endothelial wall and are a useful adjunct in the treatment of malaria.

Patent EP-0572123-A3 (EP)
IPC: G05B19/42
Filed: 1993-04-30
Abstract: For digitising a surface portion of a three-dimensional 
article a light source (14) is provided which 
projects onto the surface portion to be digitised of an 
article (S) a narrow band of light which extends over the 
surface portion. In addition, by effecting relative 
movement between the article and the light source (14) 
the narrow light band is caused to traverse progressively 
over the surface portion from one end thereof to the 
other. A camera (22) comprising a two-dimensional array 
of cells (26) monitors the location of the narrow light 
band at successive localities along its traversed path, 
the cells of the camera being illuminated according to 
the incidence thereon of light reflected from the narrow 
beam, and processor means is provided whereby the 
location of the narrow light band at selected intervals 
in its traverse are converted to digitised coordinate 
axis values, along three axes, said values thus being 
representative of the contour of the surface portion. 
The apparatus may be free-standing, serving to digitise 
the surface of an article, e.g. a shoe bottom, in an 
individual operation, or alternatively may be 
incorporated in a machine for effecting a progressive 
operation, again, e.g. on shoe bottoms. The apparatus 
may also be used for monitoring edges of components and 
for determining the configuration of marginal portions of 
such components, in order to enable the operating path of 
a tool at or adjacent such edge to be automatically 
determined, or may be used in a machine for pulling an 
article over a former e.g. a shoe pulling and lasting 
machine.

Title: Synchronizing asynchronous circuits for testing operations.
Inventor: KROMER STEPHEN C
IPC: G06F11/22
Filed: 1994-08-03
Abstract: An apparatus for synchronizing a plurality of asynchronous circuits during testing operations is provided. The apparatus includes first and second clock inputs, a test mode input, and an output. The apparatus receives a first clock signal from a first clock at the first clock input, and a second clock signal from a second clock at the second clock input. Responsive to the state of a test mode signal at the test mode input, the apparatus generates either the first clock signal or the second clock signal at the output. A first circuit is arranged to be driven by the output of the apparatus, while a second circuit is driven by one of the first or second clocks. Consequently, the first and second circuits are driven by different clocks when the test mode signal is in one state, and driven by the same clock when the test mode signal is in another state. Because the first and second circuits are driven by the same clock during testing operations, the timing of the communications between the circuits is predictable, making it possible to perform certain testing techniques that are not possible when the timing of inter-circuit communication is not predictable.
