Title: Expanding the t cell repertoire to include subdominant epitopes by vaccination with antigens delivered as protein fragments or peptide cocktails
Inventor: DIETRICH JES
IPC: A61K39/02
Filed: 2007-06-26
Abstract: The present invention teaches a convenient way of inducing a broad recognition of dominant and subdominant responses to epitopes of any given antigen of importance for prophylaxis or treatment of a chronic disease by immunizing with pools of overlapping fragments (synthetic peptides e.g. 10-30 mers with 2-20 aa overlap) of the desired antigen in appropriate adjuvants. The T cell repertoire is primed to include not only the immunodominant epitope recognized when the intact molecule is used for immunization and induced by the chronic infection itself, but induce a much broader and balanced response to a number of the subdominant epitopes as well. The resulting T-cell response to subdominant epitopes is important for protection against chronic diseases that on their own induces a response focused only towards immunodominant epitopes. The major advantage of the present invention is that it requires no prior knowledge of the precise localisation and identity of the subdominant epitopes and their recognition in a human population, but expands the T-cell repertoire and thereby the total number of epitopes recognized by specific T cells primed by vaccination from a few immunodominant epitopes to multiple of epitopes of vaccine relevance. For chronic disease controlled by humoral immunity the T helper cell response primed by the peptide mix may conveniently be boosted by the full size protein for maximum induction of an antibody response as well.

Title: Elevator car brake with shoes actuated by springs coupled to gear drive assembly
Inventor: GLASER WALTER
IPC: F16D65/28
Filed: 2009-04-20
Abstract: An elevator car braking apparatus includes a gear drive assembly for compressing one or more springs which are coupled by a cam follower to one or a pair of brake shoes. When the springs are released from a compressed state, the brake shoes engage and grip hoisting ropes, part of the hoisting apparatus or the car guide rails, within a predetermined time from the start of a brake application cycle. During a brake application cycle, the springs move the cam follower along cam surfaces shaped and disposed to cause the cam follower to move at least one of the brake shoes toward the other brake shoe.  The gear assembly includes clutch means for disengaging from and engaging with a gear or axle of the gear assembly during decompression and compression of the springs, respectively. A  resilient material in the braking apparatus initially accelerates movement of the cam follower when the springs begin to decompress, and may protect gears of the gear assembly from damage at the end of a brake release cycle.

Inventor: JIN XIAOMING
IPC: A61K6/893
Filed: 2007-06-14
Abstract: This invention relates to photopolymerizable & photocleavable resin monomers and resin composite compositions, which feature by its unique balanced overall performance including very low polymerization shrinkage and very low shrinkage stress as well. The photoreactive moiety incorporated into such new resin's main frame enable to make the resin and/or the cured resin networks that are based upon such resin photocleavable. Thus the polymerization rate of free radical reaction for (meth)acrylate-based resin systems should be substantially reduced since it alter the network formation process and consequently allow the shrinkage stress getting relief significantly. In addition, it is expected that radically polymerizable resin systems containing such P&P resin would find wide range application in microelectronic, special coating and restorative dentistry where the dimensional stability and contraction stress within cured materials are critical to the total performance.
