A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber. A main filter assembly, preferably including filter medium comprising polytetrafluoroethylene (PTFE), is located in the cyclonic chamber so that a suction airstream moving from the main suction opening to the inlet of said suction source by way of the cyclonic airflow chamber passes through the filter medium thereof after said airstream moves in a cyclonic fashion within the cyclonic airflow chamber to remove residual particulates from the suction airstream before it leaves the cyclonic chamber. A HEPA filter can be provided to filter the suction airstream exhausted through the outlet of the suction source prior to the airstream being discharged from the vacuum.

An umbrella frame provides a stable and enduring support for an umbrella canopy while also allowing canopies of varying shapes and sizes to be mounted thereto. The umbrella frame includes a hub assembly, namely, a main hub member mounted about a central pole member of the umbrella frame which offers improved means for attaching brackets thereto which are structured to pivotally receive a plurality of strut members therein, which strut members are, in turn, pivotally secured to a plurality of rib members interconnected with an upper, secondary hub. The main hub member of the present invention preferably includes an upper portion, a lower portion, and a channel having at least one ledge formed therebetween, with a band formed from a flattened strip of metal secured within the channel about the hub member. The channel is formed to have the same general height dimension as the brackets, which are secured to the band and the hub member and are confined within the space defined by the channel so as to prevent rotation or twisting thereof. As such, the present invention provides for an umbrella frame which is more sturdy and durable and yet, which allows the size and shape of the attached canopy to be readily varied.

A range has burner elements which are connected in series with a temperature switch. Upon reaching a predetermined temperatures, the switch opens and power to the burner element is secured. The burner elements are preferably open coil units, but radiant burner elements may employ similar technology with a lower upper threshold than prior art units have used. Lowering the temperature in a cooking utensil below common ignition temperatures while still allowing boiling is an objective of many embodiments.

The present disposable push up bra liner consists of a pair of bra cup pads and a center pad, each having an adhesive side for removably attaching said pad to a bra and an absorptive side composed of four separate layers. The present invention provides a novel and comfortable means for absorbing excessive perspiration around the bra line in order to avoid unsightly stains on the wearer's surrounding clothing and odors. The present invention is simple to use, easy to install, and may be freely disposed of at any point. The disposable bra liner further provides vertical support for a wearer's breasts, essentially converting any conventional bra into a push-up bra.

A replaceable hollow fiber membrane filter device comprising an upper cap, a lower cap, and a cartridge. The cartridge has multiple hollow fiber membrane bundles inside, and an upper and a lower membrane tube covers which are used to fix two ends of hollow fiber membrane bundles. The bottom of each hollow fiber membrane bundle has a lower membrane lagging; the top of each hollow fiber membrane bundle has an upper membrane lagging which extends outward to make a flow way; on the lower membrane tube cover there has multiple slots which conjugate with the fringe of the lower membrane lagging, and on the upper membrane tube cover there has multiple sockets which conjugate with the fringe of the upper membrane lagging, and both are seal-connected by a disassembling structure. The upper end and the lower end of each hollow fiber membrane bundle respectively goes through the upper and the lower membrane lagging, and is mounted inside the upper and the lower membrane tube cover, and seal-connected by disassembling structure. Therefore, the present invention may provide a method of replacement or cleaning single hollow fiber membrane bundle instead of replacing whole filter device, so the cost is down.

The present invention relates to a disposable reaction cuvette segment for use in full automatic chemistry analyzers, which is a curved cuvette segment (1) comprising at least three open-ended cuvettes (11). Connecting webs (12) are arranged on the top surface between every two adjacent cuvettes (11) and on the upper part of the front and back sides of the cuvettes. The lower part of the cuvette (11) is an optical surface (13). Two fixing protrusions (15) of the same height arranged at the same level are provided vertically down on the top of the inner side of the curved cuvette segment (1), and inside each of these protrusions there is set a vertically oriented mounting hole (16) having a round or tapered shape. As compared with the prior art, the present invention has such advantages as simpler structure, accurate positioning and convenience for installing and replacing.

A non-powered roller conveyor for conveying parts along a conveyor path includes a downwardly sloped conveyor support frame with a plurality of rollers rotatably mounted along the frame. The rollers comprise a length of prefabricated roller top conveyor chain mounted along a top surface of the conveyor frame. The conveyor chain includes a plurality of links connected together by pivotal connectors that permit sideways articulation of the links with respect to each other. Transverse rows of rollers are rotatably mounted on the links to permit products to roll along the conveyor. The rollers are easily replaceable when necessary. The conveyor follows a downwardly extending spiral path comprising a series of inclined straight sections interconnected by inclined bend sections. Both the straight and bend sections are inclined so that parts roll along the conveyor path under the influence of gravity.

A travel case for liquid cosmetics, medications and the like includes an interior pocket with a separate transparent plastic pouch for the liquid materials such as cosmetics. Access to the interior of the bag may be effected through a principal access opening in the top of the bag. Access to the interior pocket which holds the pouch may also be effected through an auxiliary opening in the side wall of the bag. The access opening to the pocket within the bag as well as to the interior of the bag are all oriented in the same direction.

A high-speed photographic printer having an imaging active matrix liquid crystal display with a corrective lens arrangement confronting the imaging active matrix liquid crystal display. The high-speed photographic printer includes a light sealable housing, a lens drawer located between the imaging active matrix liquid crystal display, an operating system that perceives RAM as a hard drive, and a light stream having an orange hue that is conventionally provided by a film negative. Image information is provided to the imaging active matrix liquid crystal display. Customer information associated with the image information is imprinted on the photosensitive material adjacent to the image with an optical marker in the light sealable housing. Such imprinted information is sensed down line from the high-speed photographic printer such as at a cutting station.
