Abstract: In regards to the traditional badminton racket, it is known that the racket is difficult to transport since the shaft is lengthy and obtrusive. In many cases, a separate bag is needed to protect the racket while in transit from one location to the next. In this invention, the badminton racket shaft is replaced with a folding shaft to allow the badminton racket to fit into smaller spaces. The shaft will consist of two segments, supported on the interior with an elastic material to keep both segments connected. Before use, a sturdy fastening mechanism will lock the two segments together longitudinally in order to form one shaft. An additional support will slide to cover the shaft joint and lock both shaft segments in place.

Title: Continuous neat polymerization and ambient grinding methods of polyolefin drag reducing agents
Inventor: CALLAWAY MIKE
IPC: C08F2/00
Filed: 2003-11-03
Abstract: A process for continuously producing a polymer drag reducing agent (DRA) is described. The process concerns mixing a monomer and a catalyst in at least one continuously stirred tank reactor (CSTR) to form a mixture. The mixture is continuously injected into a volume continuously formed by a thermoplastic material, such as polyethylene. The thermoplastic material is periodically sealed off to form a temporary container or bag. The monomer is permitted to polymerize in the temporary container to form polymer. In one non-limiting embodiment, the polymerization in the bag takes place within an inert, circulating fluid that accelerates heat transfer. The polymer and the temporary container are then ground together, preferably at non-cryogenic temperatures, to produce a particulate polymer drag reducing agent. In one preferred, non-limiting embodiment, the grinding or pulverizing occurs in the presence of at least one solid organic grinding aid. Finally, the particulate polymer drag reducing agent may be combined with a dispersing fluid.
Patent CA-2514807-A1 (CA)
Inventor: HIROHARA YOKO
IPC: A61B3/103
Filed: 2004-01-29
Abstract: It is possible to estimate optical characteristic according to a pupil diameter in daily life of an examinee, correction data near to the optimal prescription value, eyesight, and sensitivity. A calculation section receives measurement data indicating refractive power distribution of an eye to be examined and pupil data on the eye and calculates lower order and higher order aberrations according to the measurement data and the pupil data (S101 to 105). For example, a pupil edge is detected from the anterior ocular segment image and a pupil diameter is calculated. By using this pupil diameter, lower order and higher order aberrations are calculated. According to the lower order and higher order aberrations obtained, the calculation section performs simulation of a retina image by using high contrast or low contrast target and estimates the eyesight by comparing the result to a template and/or obtains sensitivity (S107). Alternatively, according to the lower order and the higher order aberrations obtained, the calculation section calculates an evaluation parameter indicating the quality of visibility by the eye to be examined such as the Strehl ratio, the phase shift (PTF), and the visibility by comparison of the retina image simulation with the template. According to the evaluation parameter calculated, the calculation section changes the lower order aberration amount so as to calculate appropriate correction data for the eye to be examined (S107). The calculation section outputs data such as the eyesight, sensitivity, correction data, and the simulation result to a memory or a display section (S109).

Patent CA-2535224-A1 (CA)
Inventor: SHELTON FREDERICK E IV
IPC: A61B17/28
Filed: 2006-02-03
Abstract: A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A  traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.
