Title: Method and apparatus for non-invasively evaluating endothelial activity in a patient
Inventor: SCHNALL ROBERT P
IPC: A61B5/026
Filed: 2001-10-22
Abstract: A method and apparatus for non-invasively evaluating endothelial activity in a patient, particularly for indicating the presence of an endothelial dysfunction condition, by applying an occluding pressure to a predetermined part of an arm or leg of the patient to occlude arterial blood flow therein;  maintaining the occluding pressure for a predetermined time period; removing the occluding pressure after the elapse of the predetermined time period to restore arterial blood flow; monitoring a digit of the arm or leg by a digit-probe for changes in the peripheral arterial tone therein before and after the application of the occluding pressure to the arm or leg of the patient; and utilizing any detected changes in the peripheral arterial tone for evaluating endothelial activity in the patient. Particularly important advantages are provided when the occluding cuff is applied to the digit of the patient receiving the monitoring digit-probe, on the proximal side thereof with respect to the patient's heart, and also when a reference digit-probe is applied to another digit, not influenced by the occluding pressure, to compensate for shifts inherent to vascular beds.

Title: Immunomodulatory peptides derived from heat shock proteins and uses thereof
Inventor: ALBANI SALVATORE
IPC: A61K45/00
Filed: 2001-10-31
Abstract: A method of modulating an immune response in a subject is disclosed. The invention is based on the discovery that an effective therapeutic strategy for ameliorating the inflammation-related symptoms of an immune-mediated disease, such as arthritis, can be achieved by modulation of the underlying immune response itself, rather than by merely addressing the resulting inflammation.  This strategy can be used to regulate the inflammatory response and is applicable to a variety of contexts in which immune modulation is desired, such as mucosal tolerization, DNA vaccination, anergy induction, active immunization, and ex vivo modulation of antigen-specific T cells. In one embodiment, the method comprises administering to the subject a bacterial dnaJ  peptide or a human homolog or a non-homologous human isoform thereof.

Title: Alveoles de balle de golf a evidement sous-jacent
Inventor: KENNEDY THOMAS J III
IPC: A63B37/00
Filed: 2001-12-06
Abstract: L'invention concerne une nouvelle configuration d'au moins certaines des alvéoles de la surface d'une balle (2) de golf, caractérisée par des parties (16) évidées par-dessous la surface concave (10) de la balle. Les alvéoles (4) à évidement sous-jacent présentent un premier diamètre à la surface de la balle, et, au-dessous de la surface, un deuxième diamètre supérieur au premier diamètre. De cette manière, une partie de la surface (2a) de la balle surplombe une partie annulaire de l'alvéole, sur le pourtour de celle-ci. Les parties (16) ainsi évidées produisent une turbulence supplémentaire à la surface de la balle (2) lorsque celle-ci traverse l'air, qui améliore l'efficacité aérodynamique des alvéoles de manière à réduire la résistance de frottement et à accroître la distance parcourue par la balle frappée.

Inventor: MIGLIORI LUCIANO
IPC: B25B5/06
Filed: 2003-06-27
Abstract: A clamping device for work pieces; the device comprises a box-shaped body having un longitudinal axis, at least one movable gripping member, and control means for moving the gripping member between an advanced and a retracted position.        The gripping member is operatively connected to the control means by an articulated system having an L-shaped lever, and a toggle lever device; an arm of the L-shaped lever defines a first connecting rod pivotally supported by a first pivotal axis and connected to the clamping member by a first articulation axis. A second connecting rod is pivotally supported by the box-shaped body to rotate according to a second pivotal axis, and in turn is connected to the clamping member by a second articulation axis. The two connecting rods are of different lengths, and the pivotal axes or articulation axes, lie in a plane passing through a reference line which forms an angle with respect to the longitudinal axis of the box-shaped body.

Title: Methods for the treatment of hiv and other viruses
Inventor: HARRIS MICHAEL F
IPC: A61P31/18
Filed: 2002-03-25
Abstract: A treatment for the persons infected with viruses such as HIV. The method takes advantage of the anesthetic membrane effect brought about by certain gases under pressure. A patient infected with HIV, for example, is placed in a pressurized chamber and exposed to one or more gases under pressure. In this environment, molecules or compounds bind to specific attachment sites on surfaces of host cells and on the virus. These attachment sites are the same sites that are required by the virus to attach to host cells during the virus's replication process. The result is that viruses are prevented from replicating. In the case of HIV, without replication, the virus is also prevented from mutating. This deleterious effect on the virus allows the body's immune system to reconstitute itself in numbers sufficient to cause clinical remission. The present method generally comprises the steps of selecting the gases, pressures and duration to be used inside a pressurized chamber, and exposing the patient to the selected conditions.

Title: Natural gas liquefaction
Inventor: WILKINSON JOHN D
IPC: F25J3/02
Filed: 2002-06-04
Abstract: A process for liquefying natural gas (50) in conjunction with producing a liquid stream containing predominantly hydrocarbons heavier than methane (41 ) is disclosed. In the process, the natural gas stream to be liquefied (31) is partially cooled, expanded to an intermediate pressure (14,15), and supplied to a distillation column (19). The bottom product (41) from this distillatio n column preferentially contains the majority of any hydrocarbons heavier than methane that would otherwise reduce the purity of the liquefied natural gas (50). The residual gas stream (37) from the distillation column (19) is compressed (16) to a higher intermediate pressure, cooled under pressure (60 ) to condense it, and then expanded (61) to low pressure to form the liquefied natural gas stream.

IPC: B65H20/16
Filed: 2003-11-27
Abstract: Flat objects (10) are packaged with a packaging material (1), which is supplied as a quasi-endless web. For this purpose, the packaging material (1) is gripped at one of its surfaces by gripping elements (6) spaced at intervals. During conveyance of the pack- aging material (1) by the gripping elements (6) the distances between the gripping ele- ments (6) are reduced and the packaging material (1) is made to buckle between the gripping elements to one side such forming a string of bags (1'). During further con- veyance these bags (1') are charged with the flat objects (10), are severed from the string of bags, and are sealed. The packaging material is supplied, e.g. with its width aligned essentially horizontally, is gripped from above by the gripping elements (6), buckles downwards by gravity, and the bags are charged from above. The formation of the string of bags is very simple, and for adjusting the bag depth the only measure needed is a corresponding adjustment of the original distance between the gripping elements (6). Buffering the bags prior to being charged or to being sealed is also very easy.
