Title: Lockable microelectromechanical actuators using thermoplastic material and methods of operating same
Inventor: WOOD ROBERT L
IPC: H01H61/02
Filed: 2001-03-14
Abstract: Lockable microelectromechanical actuators include a microelectromechanical actuator, a thermoplastic material that is coupled to the microelectromechanical actuator to lock the microelectromechanical actuator, and a heater that melts the thermoplastic material to allow movement of the microelectromechanical actuator. When the thermoplastic material solidifies, movement of the microelectromechanical actuator can be locked, without the need to maintain power, in the form of electrical, magnetic and/or electrostatic energy, to the microelectromechanical actuator, and without the need to rely on mechanical friction to hold the microelectromechanical actuator in place. Thus, the thermoplastic material can act as a glue to hold structures in a particular position without the need for continuous power application. Moreover, it has been found unexpectedly, that the thermoplastic material can solidify rapidly enough to lock the microelectromechanical actuator at or near its most recent position.
Patent CA-2342831-A1 (CA)
Inventor: KUNST LJERKA
IPC: C12N9/10
Filed: 2000-07-21
Abstract: In various aspects, the present invention provides nucleic acid sequence encoding all or part of a new plant long chain fatty acid condensing enzyme (a fatty acid elongase), designated herein as KCS2 (for beta-ketoacyl-coenzyme A  synthase 2). In some embodiments, KCS2 may mediate the biosynthesis of C18, C20, C22 and C24 fatty acids. The activity of the enzyme is typically characterized by two carbon (malonyl-CoA) additions to C16, C18, C20 and C22 moieties (C16-C22 acyl CoA molecules), i.e. condensation of malonyl-CoA with a C16, C18, C20 or C22 acyl-CoA. The fatty acids produced by the enzyme may for example be saturated 18:0, 20:0, 22:0 and 24:0 fatty acids. The invention includes recombinant nucleic acid molecules comprising a heterologous nucleic acid coding sequence encoding the plant long chain fatty acid condensing enzyme.

Title: A friction tiebar clamp
Inventor: GLAESENER PIERRE
IPC: B29C45/67
Filed: 2000-03-15
Abstract: A mechanism (10) for applying a clamping force to a columnar member (20), such as a tiebar, is described. The clamping mechanism includes a compressible member (22) surrounding the columnar member (20) for gripping the columnar member and transmitting a clamping force thereto, which compressible member is slidable along the columnar member. The mechanism further includes a clamping piston (40) for applying a clamping force, which clamping piston (40) has a bore (44) with an engaging surface (46) for receiving and frictionally engaging the compressible member (22). The frictional engagement between the compressible member (22) and the engaging surface (46) prevents any relative sliding movement between the compressible member and the clamping piston. The mechanism still further includes a sliding piston (50) for applying a clamping force and for causing the compressible member (22) to slide along the columnar member from an initial position to a preload position where the compressible member (22) is compressed by contact with the engaging surface (46) as the compressible member moves between the positions. Compression of the compressible member causes it to grip the columnar member and apply an initial clamping force. The main clamping force is applied to the compressible member and hence to the tiebar by moving the clamping piston (40) to a clamping position. A method for applying a clamping force to a mold using the clamp mechanism of the present invention is also described.
