Title: Quick release system for mounted rollers
Inventor: POTTIER BENOIT
IPC: B65H27/00
Filed: 2000-10-04
Abstract: A quick release mechanism for a roller (6, 7) wherein the roller (6, 7) is mounted in a frame and rotationally driven (for example, a roller (6, 7) carrying a roll of stretch wrapping film (4) in a stretch wrapping head (1)).      The quick release mechanism includes a pair of stub axles (22, 43) which support either end of the roller (6, 7) in the frame. One of the stub axles (22) are fixed within the frame and driven by a motor (8). The connection between this driven stub axle (22) and the roller (6, 7) ensures that no relative rotational movement occurs. The other stub axle (43) is "lockable" in a hole in the frame but is removable therefrom. The connection between the removable stub axle (43) and the roller (6, 7) allows free relative rotational movement. Withdrawal of the removable stub axle (43) from the frame allows the roller (6, 7) to be disconnected from its connection with the driven stub axle (22) and removed from the frame. Refitting of the roller (6, 7) is simply a reversal of this process.
Patent CA-2326705-A1 (CA)
Title: Crank system with sinusoidal piston motion
Inventor: BARSKI WOJCIECH GRZEGORZ
IPC: F02B3/06
Filed: 2000-12-18
Abstract: A crankshaft system for internal combustion engines built for record rotational or racing speeds and power because of a pure sinus piston motion, low friction and small size. The system is based on hypocycloid movement, but with small diameter of (eccentric) circular cam driving one- or double-sided piston. The circular cam performs flat motion: uniform rotation in its own plane plus a straight-line sinusoidal reciprocal movement. It substitutes a connecting rad and drives the piston directly. A piston skirt and wrist pin are absent, the piston itself may be double-sided (boxer), in one piece, and light. Self compensating mechanism maintains high precision of sinus piston motion over the life of the system, compensating for wear and thermal dilation. Full balancing even of one-cylinder engine may be achieved. An engine 90° V2 is inherently fully balanced. Intrinsic lack of forces acting on cylinder walls means high mechanical efficiency -cylinders are subjected only to the piston's rings friction. This makes the system easy to cool, or allows for more power. Very suitable for all supercharged engines and Direct Injection Diesel. Suitable for one-cylinder engines, V2 (especially 90°), V, boxer, X, star or in -line.

Title: Method and apparatus for measuring torque
Inventor: LAMBSON VERNON A
IPC: G01L3/10
Filed: 1999-10-21
Abstract: A method and apparatus for measuring torque of a rotating shaft is provided.  In one embodiment, the apparatus (10) includes a transducer assembly (12) that is attached to a shaft. The transducer assembly includes a first plate member (14), a plurality of webs (18) extending from the first plate member and a second plate member (16) connected to the webs. A plurality of strain gauges are mounted on the transducer assembly at selected locations and in selected patterns. As torque is applied to the shaft, the torsional load from the shaft causes stress in the first plate member, the web members, and the second plate member. The strain gauges measure this stress and generate signals that provide a measure of the stress. The signals transmitted from the sensing circuit are compared with calibration data, and the torque value is inferred. In one embodiment, the strain gauges are arranged in opposing pairs on the transducer assembly and electrically connected as a Wheatstone bridge, so that strain resulting from non-torsional loads is canceled from the measured signal, thereby improving torque measurement accuracy. In another embodiment, the strain gauges are located on thinned regions in the transducer assembly which are fashioned for the purpose of creating areas of localized high stress. In another embodiment, the transducer assembly includes a decoupling aperture. The decoupling aperture miminizes hysteresis due to warping and bending of the transducer assembly.
