Granted: 1999-12-07
Abstract: Protein expression levels from Bordetella strains, particularly Bordetella pertussis, are altered by genetic modification to a natural Bordetella strain whereby one or more of the natural genes, particularly including the TOX, FHA, CYA and PRN genes, is deleted from the genome of the natural strain and one or more of the natural genes or a genetic mutation thereof, particularly a genetically-detoxified TOX* gene, or a hybrid gene, is inserted into the genome of the natural strain to provide at least two copies of one or more of the natural genes or genetic mutation thereof or hybrid gene, singly or in tandem. The altered genotype Bordetella strain is useful in producing whole-cell or defined component vaccines against Bordetella, particularly whooping cough, which may be employed in combination with other vaccines.

Title: Plate holder for an overground display
Inventor: GILES TREVOR P H
IPC: A47G1/16
Filed: 1992-08-04
Granted: 1995-07-18
Abstract: A plate holder for hanging a plate to a wall for display, comprising a spiderweb-like net and hooks to attach the plate to the net. The net is preferably made of peripheral threads positioned to form a plurality of concentric circles equally spaced and linked together with a set of radial threads positioned in pairs. The net is placed behind the plate and the hooks are positioned to simultaneously engage the plate lip and one of the concentric circles according to size of plate. For a better fitting, the hooks are provided with two snapping recesses, located at different positions on the hooks, for grabbing the net. For smaller plates, the external circles on the net can be cut off. The hooks are made of a material that is not likely to scratch the plates, such as nylon. The plate holder is then fixed to the display site, such as a wall, by a means, such as a conventional painting hook, grabbing one of the threads of the net. This plate holder provides a very reliable means for mounting a plate without damaging it. This plate holder also permits viewing identifications marks on the back of the plates without having to remove it and is adaptable to a multitude of plate sizes.

Abstract: A multipurpose hemofiltration system (10) and method are disclosed for the removal of fluid and/or soluble waste from the blood of a patient. The system (10) and method are equally applicable to adult, pediatric and neonatal patients. The system (10) continuously monitors the weight of infusate in a first reservoir (50) and drained fluid (76) in a second reservoir (74) and compares those weights to corresponding predetermined computed weights. When necessary, the pumping rates of the infusate (52), drained fluid (76) and blood are adjusted in order to achieve a preselected amount of fluid removal from the patient's blood in a preselected time period. Application of this system (10) and method provide repeatable and highly precise results.

Abstract: The link permits communications between cars of a railway or subway trains.   On at least a first one of the cars,    a   multiplexer   multiplexes   digital   signals representative of the status of various systems on the car, and processes them into a first digital trainline signal.  A transmitter includes a modulator which converts the digital trainline  signal  to  a RF  signal,  and the RF  signal  is transmitted,  by an antenna,  through free  space from the first car to a second car.   The second car includes an antenna for receiving the RF signal, and a receiver for de-modulating the signal and converting it to a second digital trainline signal.  A demultiplexer demultiplexes the second digital trainline signal into appropriate formats readable by the train systems on board the second car.   Both the first   and   second   cars   include multiplexers   and demultiplexers,  and  transmitters  and  receivers,  so  that communication is possible between the first car and the second car as well as between the second car and the first car.

Abstract: A method for partitioning programs into multi-procedure modules for efficient compilation.  During interprocedural analysis, a weighted callgraph of the program is constructed in which weights on nodes represent code size of each procedure and weights on edges between the nodes represent execution counts between procedures. A coloured interference graph is built from the analysis information, and is used to induce weighted sub-graphs of the callgraph containing no interferences between procedures in each sub-graph. The procedures from a single sub-graph are combined into one or more modules; procedures with the highest weighted edges between them are combined in a module first until the cumulative node weight of the module reaches a preset limit on memory size.
