摘要： A reciprocating rotary action actuator consisting of a rotor and stator that can be added to a bi-directional rotary motor or galvanometer scanner, where the stator has a ring magnet and a pair of soft iron pole pieces that concentrate the flux of the ring magnet into a concentric set of narrow, uniformly spaced, axially oriented, magnetic flux fields intersecting the rotor's field of travel. The rotor has small permanent magnets embedded in the periphery of a nonconductive, nonmagnetic rotor core. The rotor magnets have the same number and spacing as the stator's magnetic flux fields. The magnet poles are oriented opposite the flux fields of the stator pole pieces, so that upon rotation, the rotor magnets encounter the stator flux fields at each end of rotor travel, creating an opposing force that reverses the angular direction of the rotor with minimal requirement for actuator current and generation of thermal losses.

摘要： The invention is an improved nursing bottle, providing a new valve within its bottom structure. A flexible disk is disposed within the bottom end cap of the nursing bottle, clamped at its periphery to the periphery of the base when the bottle is assembled. The disk has a ring of slits near its periphery which are closed when pressure inside the bottle equals ambient pressure. The slits are further sealed by contact with the base. Holes, which are sealed closed by contact with the disk, are provided in the base within a central portion which does not contact the slits in the disk. When pressure within the bottle drops, the disk bows upwardly in its center, opening the valve and allowing air to enter the bottle. When pressure within the bottle increases, the valve again closes.

摘要： A laser flashlight employs a laser emitter disposed within a housing for emitting a coherent light along an optical axis toward the light emitting end of the housing. A power supply selectively applies electricity from a battery pack disposed within the housing to the laser emitter. An optical system disposed within the housing intermediate the laser emitter and the light emitting end of the housing includes a laser element pumped by the laser emitter, a frequency/wavelength converter, and a resonator, to form the coherent light into a laser beam. A beam expander receives the laser beam, disperses the laser beam, and transmits the dispersed laser beam from the light emitting end of the housing into the ambient environment. The dispersion of the laser beam is such that the laser beam is safe for the human eye at the light emitting end of the housing.

摘要： A diode-pumped gas laser includes a source of optical diode-pumping light and a gas cell having a first optical window for receiving the diode-pumping light. The gas cell contains a laser gas including a lasing gas comprised of at least one absorbing and lasing atomic or molecular gas. The lasing gas has an optical absorption band which is at least partially overlapped by the bandwidth of the diode-pumping light. The gas laser also includes a gas laser resonator for providing an output laser beam which is emitted from the gas cell via a second optical window. The output laser beam has one or more laser wavelengths. The gas laser may also include diode optics for directing the diode-pumping light through the first optical window and a heat power regulation system for regulating the temperature of the source of optical diode-pumping light.

摘要： A bottom for a paper cup is formed by advancing a punch against a paperboard web to push the web against a cutting edge which cuts out a circular cup bottom blank from the web. The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surface of a sleeve. A reciprocable draw is advanced against a center portion of the blank to push the center portion into a circular opening of the sleeve while maintaining the clamping force, to cause the center portion of the blank to become stretched. The clamping force is then progressively released to permit the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state.
摘要翻译： 纸杯的底部通过将冲头推向纸板网而形成，以将纸幅推向相对于从卷筒纸切出圆形杯底部坯料的切割边缘。 冲头保持在向前状态，以将坯件的外周部分不可移动地抵靠套筒的表面。 相对于坯料的中心部分进行往复式拉伸，以将中心部分推入套筒的圆形开口中同时保持夹紧力，从而使坯料的中心部分变得拉伸。 然后逐渐释放夹紧力，以允许外周部分进入开口并弯曲成形成以大致直角延伸的唇缘。 唇部在形成于拉伸部和开口部的表面之间的间隙内被压缩。 由于坯料的拉伸，唇部中形成的褶只是以非褶皱状态变平的微细褶皱的形式。

摘要： A surgical biopsy instrument for the extraction of at least one tissue sample from a body is disclosed having a piercing needle for penetrating the body. The piercing needle has a distal piercing tip and an open proximal end and a passageway extending therebetween. The piercing needle has at least one tissue receiving port adjacent to the piercing tip, and the tissue receiving port communicates with the passageway for the reception of a tissue sample therein. A cutting member is removably disposed within the passageway of the piercing needle and the cutting member has a proximal end and a distal sampling segment. The distal sampling segment has a distal cutting edge and a bore extending therein. The distal sampling segment is moveable across the tissue receiving port of the piercing needle for the cutting of a tissue sample and the tissue sample is received within the bore of the distal sampling segment. The distal sampling segment is breakable from the elongated cutting member.

摘要： A beverage container has a straw-dispensing mechanism that is disposed within the container to bring the straw into alignment with the orifice in the top of the container. When the orifice is opened, the straw elevates through the orifice to become accessible to the user. In one embodiment, the straw is attached to a buoyant member which urges the straw into contact with a contoured surface on the can lid. In a second embodiment, the straw engages a floating member which is urged against the lid of the container. In a third embodiment, a buoyant member is integrally formed with the straw and is disposed orthogonally within the body of the can. In a fourth embodiment, the floating member includes a surface treated for facilitating the nucleation of CO.sub.2 thereon. In a fifth embodiment, the floating member is provided with a skirt for entrapping a head space gas bubble under the floating member. In a sixth embodiment, the floating member reacts to a change in pressure to disengage from the container wall. In a seventh embodiment, a latch is provided on the floating member for releasing the floating member from engagement with the container walls. In an eighth embodiment, the floating member is provided with a threaded aperture for releasably engaging a threaded member on the bottom of the container. In a ninth embodiment, a straw positioning member is provided with an inertia latch which opens to increase the diameter of the straw positioning member such that it engages the container wall.
