Patent CA-2181178-A1 (CA)
Inventor: ANDREASCH WOLFGANG
IPC: G02B7/02
Filed: 1995-11-10
Abstract: A mechanical fastening system for (micro-)optical elements (3) is presented which for their part are mounted in an individual module in the form of a rectangular parallelepiped (2). Standard components (1) of this type are initially mounted on a stool-like frame, which can for example be in the form of a "tripod" (5) or a "ball leg" (47-49). The frame has a platform (6) from which at least 3 legs can be offset in such a way that they form either spherical segments (40-42) or limbs (7-9) which for their part merge into offset foot areas (10-12). The offsetting carried out creates hinges (13-18, 43-45) which have a flexural characteristic. Further variants provide for "ball-joints" (25-27, 25a-27b) instead of (linear) hinges. The production of a corresponding basic structure (5') for a fastening system based on the object of the invention can be achieved by laser beam cutting or punching a steel sheet.    Reinforcement plates can be applied to the surface in the area of the limb (7-9). Side bracing profile pairs (40a, 40b; 41a, 41b; 42a, 42b) can be fitted in the peripheral area (46a-46c) of the spherical segment (40-42) as well. It is also possible to base the construction on thicker sheets when producing the basic structure (5'), and to then subject these to subtractive material machining processes. The proposed fastening system enables uni- or multi-dimensional layouts to be created using automatic placing and fastening technologies.

Title: Myoblast therapy for mammalian diseases
Inventor: LAW PETER K
IPC: A61K35/34
Filed: 1995-12-13
Abstract: Compositions and methods of treating mammalian diseases using myoblasts, and/or their physical, genetic, chemical derivatives. Myogenic cells that are normal, or genetically or phenotypically altered are cultured and transplanted into malfunctioning and/or degenerative tissues or organs to alleviate conditions that are hereditary, degenerative, debilitating, undesirable, and/or fatal. Treatment of these conditions is not limited to the usage of mechanical, electrical or physical properties of these myogenic cells, but includes the usage of biochemicals secreted/released by the latter. The present invention discloses the use of normal myoblasts to deliver the complete normal genome to effect genetic repair, or to augment the size, or the function of tissues or organs. Certain conditions may be better served with genetically altered myogenic cells derived from gene transduction, whereas others may be better served with cytoclimes converter cells. Endogenous biochemical(s) are used to control cell fusion of myoblasts among themselves or with other cell types. An automated cell processor within a cell bank which enables the manufacture, at a single run, of unprecedented large quantities (greater than 100 billion) of normal or genotypically or phenotypically altered myogenic cells is also disclosed.
