An efficiently packaged ready to use intermittent urinary catheter. The catheter is retained within a retention chamber having a profile that mimics the profile of the catheter by sealing the upper and a lower films together along a peripheral seal line. The retention chamber includes an enlarged compartment intermediate axial ends of the catheter in which lubricant is stored.

By intramolecular condensation reaction of 2,15-hexadecanedione in a gaseous phase with a compound of a Group II element of the Periodic Table as a catalyst, 3-methyl-cyclopentadecenones is generated. Magnesium oxide, calcium oxide, or zinc oxide is desirable as the catalyst for the intramolecular condensation reaction. (R)- and (S)-muscone is generated by subjecting 3-methyl-cyclopentadecenones obtained as above to hydrogenation by using a catalyst. Palladium catalyst is desirable as the hydrogenation catalyst. Optically active muscone is generated by separating 3-methyl-cyclopentadecenones into respective components thereof by means of precision distillation and subsequently subjecting the separated 3-methyl-cyclopentadecenones to asymmetric hydrogenation by using an optically active ruthenium complex catalyst. The production methods described above enable easy and economical production of 3-methyl-cyclopentadecenones, (R)-and (S)-muscone, and optically active muscone.

In a cellular communication network having a plurality of access points serving wireless terminals, methods and apparatus for facilitating handoff of a wireless terminal from a first access point to a second access point. In various embodiments, the process includes storing in a memory device at the wireless terminal a cell identifier, wherein the cell identifier includes a special character enabling the cell identifier to identify a plurality of access points to which the wireless terminal can be handed off; and the wireless terminal using the stored address information to determine access points to which a handoff may be implemented. One or more cell identifiers stored in the memory can be used as a neighbor list, which can be used to identify handoff possibilities or topographical adjacencies.

The invention provides an analog quartz timepiece, comprising a housing; one or more hands; a drive movement comprising gears and drive motors associated with the hands for timekeeping; a position sensor comprising a light transmitter and a light receiver positioned to define a reflective area on the dial, where the light transmitter transmits a beam of light to any one of the hands passing through the reflective area and the light receiver receives the light reflected from the passing hand; and a processor programmed to determine a position of the passing hand in the reflective area in correspondence to the reflection of the light from the hand, and to drive the movement to move the hand to a correct time position responsive to the determined position. The invention also relates to a method for providing time-correction of an analog quartz timepiece.

A method is provided to form a boss in a plate such as a bearing retaining plate which will be subject to cyclic fatigue loads. Such loads occur for example when used in a compact vehicular gearbox housing. The method comprises selecting the material of the plate to have a high strain hardening coefficient in excess of 0.35 such as austenitic stainless steel Grade 304 and press forming the boss against a die such that the radius of curvature of the region between the original plate and the wall of the boss complies with the following formula: radius = plate thickness x A In the formula "A" is a value between 0.3 and 0.7. By using the method, the arcuate portion of the boss work hardens under load to produce a region having a high local tensile strength.
