Title: Method of storing a quantity of data in a target memory location and storage system
Inventor: POCKRANDT WOLFGANG
IPC: G11C16/10
Filed: 2001-12-06
Abstract: The invention relates to a method for storing a volume of data in a target memory area according to which the volume of data is firstly saved in a non- volatile buffer memory area (10). It is then verified if the data has been successfully saved in the non-volatile buffer memory area (10). If the verification step yields a positive result, the target memory area (12), in which the predetermined volume of data should be stored, is erased. After erasing the target memory area (12), the data is transmitted from the non- volatile buffer memory area (10) into the target memory area (12). In order to terminate the memory cycle, the non-volatile buffer memory area (10) is eras ed whereby making it available for a new memory process. This results in accomplishing a reliable and uncomplicated transmission of information from a source memory (20) into the target memory (12).

Title: Automated continuous haulage system
Inventor: KANARAT AMNART
IPC: G01S17/931
Filed: 2001-10-09
Abstract: The present invention relates to an automated continuous haulage apparatus and method designed for use in underground environments. Each mobile bridge carrier (10) contains distance measurement (70) and angular position (74) means for determining the mobile bridge carrier's (10) position and the angular position of attached piggyback conveyors (30). Means for determining the ceiling height (76) are utilized to adjust the height of the piggyback conveyors (30). On each mobile bridge carrier (10), input from the various sensors is received by an electronic controller (80) that calculates the position and orientation of the bridge carrier (10) and attached piggyback conveyors (30). The controller then plans an optimal path of movement for the bridge carrier (10) and computes the rate of movement for each independently operated track assembly on the bridge carrier such that the bridge carrier (10) and piggyback conveyors (30) arrive as close as possible to the planned path.

Title: Surgical tool mechanism
Inventor: YOUNG MICHAEL JOHN RADLEY
IPC: A61B17/32
Filed: 2001-10-17
Abstract: The mechanism is applicable to a surgical tool which has a jaw (57) pivotably mounted to a distal end of a longitudinally extending support (58). The jaw is operated by action on a rearwardly facing cam follower (52, 53) by a lobe (51) on the distal end of an actuating tube (50). Rotation of the actuating tube (50) causes pivoting of the jaw (57) into and out of operative relationship with another jaw member (21) of the tool. The mechanism may be applied to any manipulative or gripping type of surgical implement, but is particularly applicable to ultrasonic tools adapted for cutting and/or coagulating.

Patent CA-2433535-A1 (CA)
Inventor: HORSLEY DAVID
IPC: A01K67/027
Filed: 2002-01-02
Abstract: Disclosed are methods of inducing or modelling the pathological state of an aggregating disease protein (ADP - e.g. tau protein) which is associated with a disease state in which the ADP aggregates pathologically (e.g. Alzheimer's disease) through an induced conformational polymerisation interaction, the method being characterised by the step of providing a membrane-localisable fusion protein comprising (i) an aggregating portion, which is derived from the ADP, or from a protein which initiates pathological aggregation of the ADP, (ii) a heterologous membrane-localising portion. Membrane-localisation of the ADP-based fusion protein is believed to cause the high-affinity capture site of the ADP protein to become exposed such that aggregation of further ADP, which may be native or heterologous to the system, to be promoted. The method can be carried out in vitro, or in cell- and animal-models, and may be used to screen for modulators of the aggregation process by monitoring aggregation e.g. by monitoring the production of the ADP-related degradation products resulting from the aggregation. Also provided are materials, processes for use in or with the methods.

Title: Corona-virus-like particles comprising functionally deleted genomes
Inventor: HAIJEMA BERT JAN
IPC: A61K35/76
Filed: 2002-05-17
Abstract: The invention relates to the field of coronaviruses and diagnosis, therapeut ic use and vaccines derived thereof. The invention provides replicative coronaviruses and replicative virus-like particles (VLPs) from which large parts of their genome are (at least functionally) deleted without abolishing their replicative capacities. Said deletion is preferably resulting in at least a functional deletion in that the corresponding gene is not or only partly expressed whereby the resulting gene product is dysfunctional or at least functionally distinct from a corresponding wild-type gene product. One striking result seen with VLPs provided with deletions as provided herein is that said deleted VLP, albeit capable of replication in vitro and in vivo, a re in general well attenuated, in that they do not cause disease in the target host, making them very suitable for therapeutic use, said as a delivery vehicle for genes and other cargo (whereby specific targeting may be provide d as well when desired), and for use as a vaccine, being attenuated while carrying important immunogenic determinants that help elicit an immune response.
