Patent CA-2258642-C (CA)
Inventor: JENKO EDWARD
IPC: B29C45/27
Filed: 1999-01-05
Granted: 2006-06-06
Abstract: A system for clamping an object, such as a heater, to a cylindrical member, such as a nozzle or a hot runner channel is described. The system has at least one deformable elastic member for applying a clamping force to the object so as to hold the object against an outer surface of the cylindrical member and an annular sleeve for compressing the at least one deformable elastic member and for directing the clamping force radially inwardly toward the cylindrical member. The deformable elastic member, in one embodiment, is formed by a spring member which surrounds the object and the cylindrical member. In an alternative embodiment, the deformable elastic member comprises a plurality of hollow tubes surrounding the object and the cylindrical member, which tubes are hollow, thin walled, and elastic. The annular sleeve is preferably formed from a material having a thermal expansion coefficient less than the thermal expansion coefficient of the material forming the cylindrical member. Thus, as heat is applied, the cylindrical member expands more than the outer sleeve causing compression of the deformable elastic member(s) and direction of the clamping force towards the object to be held against the cylindrical member. A method for using the clamping system of the present invention is also described.

Title: Load roll arrangement
Inventor: DORFEL WALTER
IPC: B65H18/20
Filed: 1997-08-05
Granted: 2004-07-20
Abstract: The invention pertains to a load roll arrangement for loading a winding arrangement with one or several wound rolls on the same axis, during the winding of a web-like material, particularly paper, onto winding cores in a multiple-drum winder wherein support drums form a winding bed, in which the winding arrangement, rotating about its axis, is supported, with a support beam (60), vertically movable dependent upon the wound roll diameter, with a multipart load roll, consisting of a number of load rollers (42), which, individually with respect to the support beam (60), are vertically movable on a mounting arrangement and can be maintained in contact with the wound roll along a nip, with means for the fluid-like, particularly hydraulic, pressing of the load rollers (42) against the winding arrangement, and with an additional adjustment device, by means of which the mounting arrangements (50) of the individual load rollers (42) can be moved to different heights, independently of each other with respect to the support beam (60) according to the specifications of the resulting differences in diameter of the winding cores. In order to apply the rolls in the presence of varying wound roll diameters, due to the additional adjustment arrangement (70) of the invention, it has become possible to bring the load rolls hanging on the support beam at more greatly varying heights, and in this way to adapt the load rolls to a "diameter profile" that results along the winding bed from winding cores that differ from each other.

Granted: 2004-01-06
Abstract: A device for roughening the worn or smooth grip of a golf club or other handled item includes a flat plate member with an aperture therethrough. A plurality of sharp-tipped serrations extend around the periphery of the aperture, with the tips defining a circular line that has a diameter greater than the maximum diameter of a grip at the free end thereof.  Adjacent serrations define a valley therebetween. In use, the plate member is clamped in a bench vise and the grip, still affixed to its golf club, is moved through the serrated aperture with a radially directed force being applied thereto so that the serrations will cut a series of grooves into the material of the grip. Preferably the grip will be rotated and moved reciprocally through the serrated aperture so that a random pattern of grooves is cut into the grip, thereby restoring the grip to a condition that approximates its original textured surface. The device may include a set of transversely extending saw-tooth-like serrations along one transverse edge thereof for roughening the grips or handles of other handled items, including golf clubs.

IPC: E01D11/02
Filed: 1999-06-16
Granted: 2005-06-07
Abstract: The invention concerns a device comprising a collar formed by two shells (10a, 10b),designed to be linked with the load-transmitting element. The cable comprises an assembly of tightly packed strands, perpendicular to the collar, in a matrix filling up the interstices between the strands. Said matrix is, wholly or partly, made of a plastic material capable of creeping when the collar is clamped. The clamping is carried out by using elongated elements (17) transmitting a clamping load to the collar shells. Said elongated elements are stressed so as to present a longitudinal elastic deformation much higher than the maximal compacting of the matrix creep, thereby preventing ill-timed unclamping of the collar.

Granted: 2011-09-20
Abstract: Surfactant protein D (SP-D) is a 43-kDa member of the collectin family of collagenous lectin domain-containing proteins that is er:pressed in epithelial cells of the lung. The SP-D gene was targeted by homologous recombination in embryonic stem cells that were used to produce SP-D (-¦-) mice. The SP-D (-¦-) deficiency caused inflammation, increased oxidant production by isolated alveolar macrophages, abnormal surfactant structure and levels, and decreased SP-A expression. Therefore, disclosed is the SP-D (-¦-) mouse as an excellent model for emphysema. Also included are models for testing emphysema therapies in the mouse model, methods for using SP-D protein or DNA as a treatment for emphysema and pulmonary infections, and diagnosis.

Abstract: A controller for an internal combustion engine detects a demand variable showing a demand from a driver, and controls an intake air volume to the internal combustion engine according to the detected demand variable. When trouble is detected in a system controlling the intake air volume, the controller switches a driving control of a vehicle to a emergency driving mode. In the emergency driving mode, the controller keeps the intake air volume to the internal combustion engine constant. The controller calculates a emergency driving control variable according to the detected demand variable, and controls the driving of the vehicle according to the calculated emergency driving control variable. The emergency driving control variable is a control variable different from the intake air volume. Thus, in the emergency driving mode, the driving of the vehicle can be controlled by the control variable different from the intake air volume, and a better drivability is ensured. -40-
