Patent CA-2479367-A1 (CA)
Inventor: PILPEL EDWARD
IPC: B60G11/02
Filed: 2003-03-18
Abstract: In a method for making a hybrid leaf spring, at least one layer of composite material is molded onto a primary leaf (60) using a mold (62) with an interior cavity (64) having a curvature for receiving the primary leaf at a depressed camber (C2) relative to its initial camber (C1). The depressed camber is between unloaded and curb load cambers of the hybrid leaf spring. The primary leaf and the layer of composite material are positioned in the mold adjacent to one another and with a layer of adhesive therebetween. The layer of adhesive is cured for bonding together the primary leaf and the layer of composite material at the depressed camber so as to generally eliminate bond line shear stress when the camber of the hybrid leaf spring is at the curb height.

Abstract: A no-draft putter club head is formed using an investment casting process, wherein one or more critical surfaces of the club head - i.e., surfaces with contours that affect the visual appearance of the club head when viewed from above - are formed substantially parallel to the draw direction of the mold. The mold includes an internal cavity corresponding to a putter club head shape, wherein the cavity includes a set of surfaces substantially parallel to the draw direction of the mold. This set of surfaces may include, for example, a toe surface, a heel surface, a top rail surface, and/or a hosel surface. A wax material is suitably poured or injected into the mold cavity to form a wax replica of the putter club head shape. The wax replica is then removed from the mold cavity along a line parallel to the draw direction.

Patent CA-2496484-A1 (CA)
Title: Densified heat transfer tube bundle
Inventor: CARTER THOMAS P
IPC: F28D7/08
Filed: 2005-02-10
Abstract: A heat exchanger coil assembly design and method of manufacture increases heat transfer surface area for a given heat exchanger size by increasing the packing density of circuits in the a given coil. The heat exchanger coil assembly preferably increases circuit density uniformly and precisely. This allows the number of circuits in the coil assembly of a heat exchanger to be increased from that which would previously have been considered possible to provide maximum heat transfer surface area for a given heat exchanger size. The coil assembly is made up of arrays of substantially equally spaced apart serpentine circuits located in the coil assembly region of the conduit, with adjacent circuits being arranged in a parallel offset fashion in which adjacent return bends are overlapping. The tubes have an effective diameter of D. Depression areas are provided at the points of overlap to locally reduce the diameter at the overlap. This provides a circuit-to-circuit with a density D/S > 1.0, preferably greater than 1.02, where S is the spacing between adjacent circuits and D is the effective diameter of the tubes. The depression areas provide only a minimal increase in internal fluid pressure drop but result in increased heat transfer surface area since additional circuits can be added in a given size constraint application. The increased pressure drop is more than offset by a resultant decrease in internal fluid pressure drop due to the increase in internal flow area. The inventive coil assembly is useful with various types of heat exchangers.

Title: Wood cutting saw chain and replaceable cutting members
Inventor: SZYMANSKI DAVID
IPC: B27B33/14
Filed: 2005-02-16
Abstract: A quick change cutting link of saw chain for cutting wood comprises a base member adapted to be pivotally connected to other links of the saw chain. The base member comprises a seat surface. A cutting member comprising a cutting edge releasably engages the seat surface of the base member. The cutting member includes sintered and compacted particles of abrasion resistant material. In particular, in one design the base member seat surface has a first taper and the cutting member includes a surface having a second taper. The first and second tapers extend at an angle ranging from about 0.5° to about 45° relative to a direction of chain travel at a close tolerance effective to cause self-locking engagement of the first taper of the seat surface and the second taper of the cutting member surface. The close tolerance is characterized by variation in the angle being not more than about 1° and, in particular, not more than 0.5 °. The invention is also directed to the cutting member itself, including a design in which one of the cutting member and seat surface includes an inverted-L shaped protrusion and the other includes an inverted-L shaped recess for receiving the inverted-L shaped protrusion. The inverted L-shaped protrusion and recess may be designed so as to form a wedge. Also included is wood-cutting saw chain containing the inventive cutting link such as saw chain adapted for use on a chain saw, timber harvester and the like.

Abstract: Compounds, genetic constructs, and cancer treatment methods 035 provided.  Expression vectors were designed to express fusion genes including hIL-2 with 0 FcT- transmembrane anchor derived from 0 subunit of the FC epsilon receptor.  mRN 0nd the IL~2tm fusion protein was expressed in transfected RD995 tumor cells. Expression of the IL~2tm protein on the tumor A511 surface membrane was confirmed by microscopy. RD995 ce11s transfected with IL-2tm or pCMV2b (empty expression vector) were implanted subcutaneously into !3 /HEN mice. Tumors in groups of mice implanted with 106 or 105 RD995 ce11s transfected with IL-2tm grew slower than controls. Without being limited to any one theory, it is believed that selective expression >f cytokines such as IL-2 on the surface >f tumors is likely to stimulate tumor-infiltrating lymphocytes that are primed and already recognize tumor antigens, enhancing tumor recognition 0nd killing, potentially avoiding toxicity associated with known cytokine therapies.

Abstract: The gait monitor system and method provides various basic gait parameters including step count, cadence, and step duration, in addition to its ability to distinguish between normal, limping and shuffling gait modes, as well as determine falls. Moreover, this gait monitor may be provided with additional sensors, e.g. beam break at the beginning and end of a corridor to estimate average walking velocity (with the distance between the beams known or determined); this enables the calculation of additional gait characteristics such as average step length and average stride length. These parameters can additionally be used to detect various gait anomalies and other diagnostic information.
