An air cleaner device for a vehicle is provided with an air cleaner body containing an air cleaner element and a snorkel connected to the air cleaner body to introduce the outside air into the air cleaner body. The snorkel extends forward of the vehicle past a side of a cylinder portion which projects upward from an engine, and a front end of the snorkel opens between right and left seats of the vehicle. With this configuration, even if the air cleaner body of the air cleaner device should be flooded, it is difficult for water to enter into the interior. Further, it is difficult for the air cleaner body to be influenced by heat, and difficult for dust to get into the air cleaner body.

A disposable cushioned aspirator which forms part of a dental or medical aspirating system. The disposable cushioned aspirator appliance described herein is intended principally to be used in dental and medical procedures where body fluids and rinse water is evacuated from the site of a procedure. An elongate tubular element has a connection end and a patient end. The patient end is exteriorly lined with a layer of soft cushioning material such as a soft thermoplastic elastomers, styrene based polymers, rubber or a porous polymer foam material to define an aspirator tip that protects the soft tissues in and around the mouth of a patient. The soft aspirator tip has external longitudinal pressure relief channels and recessed aspiration openings within the channels for control of aspiration characteristics. The aspirator tube is capable of being manually bent to a desired configuration and has an embedded structural member such as wire extending along its length and being pliable to permit bending and yet of sufficient structural integrity to maintain the aspirator in the desired configuration during use.

A conveyor belt hold down for a draper platform comprises a planar portion having a front edge, a rear edge, a left edge, and a right edge, wherein one of the left and the right edges defines a first slot or groove structure, and the other of the left and the right edges defines a first tongue structure, wherein the first tongue structure is configured to be engaged in a second slot or groove structure of a similar hold down disposed immediately adjacent to the first tongue structure, and wherein the first slot or groove structure is configured to receive a second tongue structure of a similar hold down disposed immediately adjacent to the first slot or groove structure.

A method for releasing flowable material via an automated means from a receptacle which has at least one closed end, characterised by the steps of locating the receptacle in a defined position relative to a receptacle opening mechanism, and opening the receptacle with the receptacle opening mechanism, the method characterised in that the receptacle is positioned such that it is opened substantially below the bulk of the material in the receptacle. Also disclosed is a method of releasing flowable material via an automated means from a receptacle which has at least one closed end, characterised by the steps of locating the receptacle in a defined position relative to a receptacle opening mechanism, and opening the receptacle with the receptacle opening mechanism, the method characterised in that the flowable material within the receptacle is fluidised.

Embodiments of the present invention are generally directed to apparatus and methods for a plasma-processing chamber requiring less maintenance and downtime and possessing improved reliability over the prior art. In one embodiment, the apparatus includes a substrate support resting on a ceramic shaft, an inner shaft allowing for electrical connections to the substrate support at atmospheric pressure, an aluminum substrate support resting on but not fixed to a ceramic support structure, sapphire rest points swaged into the substrate support, and a heating element inside the substrate support arranged in an Archimedes spiral to reduce warping of the substrate support and to increase its lifetime. Methods include increasing time between in-situ cleans of the chamber by reducing particle generation from chamber surfaces. Reduced particle generation occurs via temperature control of chamber components and pressurization of non-processing regions of the chamber relative to the processing region with a purge gas.

Extracorporeal cell-based therapeutic devices and delivery systems are disclosed which provide a method for therapeutic delivery of biologically active molecules produced by living cells in response to a dynamic physiologic environment. Exemplary designs are disclosed. In a first exemplary embodiment the device includes long hollow fibers in which a layer of cells are grown within the intraluminal volume or within a double hollow-filled chamber. In another exemplary embodiment the device includes a wafer or a series of wafers forms a substrate onto which cells are grown. The wafer(s) are then inserted into a device. The devices are intended to be extracorporeal. Disclosed is a device for delivering a pre-selected molecule, for example, a hormone, into a mammal's systemic circulation. The device may also deliver a member of different cell products. The device comprises an anchoring element that can be anchored to an inner wall of an extracorporeal tube for blood. The device also comprises a capsule that is held in place within the extracorporeal tube for blood or fluid by an anchor. The device is adapted to secure viable cells which produce and secrete the pre-selected molecule into blood or fluid passing the capsule. The invention also provides a minimally invasive method for percutaneously introducing into a preselected blood vessel or body cavity the device of the invention.
