A switch unit having a combined switch function and locking function for controlling industrial tools, both the locking function and the switch function being achieved magnetically.

A structure and method for forming a U-clip assembly made of a plurality of U-clips arrayed in a continuous abutting relation, each U-clip having first and second slots defined in its crown portion with first and second soft metal wires positioned, respectively, in such first and second slots, such soft metal wire forming a shallow U shape between adjacent crown portions, such first and second soft metal wires being compressed within their slots to expand within such slots for contacting and urging against the sides and bottom of each slot and being retained therein, such soft metal wire and its shallow U shape between adjacent crown portions allowing the U-clip assembly to maintain a non-curved shape and to be substantially flat in configuration.

Multiplexed electrospray deposition apparatus capable of delivering picoliter volumes of one or more substances is disclosed. The apparatus may include a unitary planar dispenser etched from a silicon wafer through microfabrication or micromachining technology. The apparatus may be used as a deposition tool for making protein microarrays in a noncontact mode. Upon application of potential difference in the range of 7-9 kV, the substances may be dispensed directly, not through a collimating mask, onto a substrate with microhydrogel features functionalized with an anchoring agent.

This invention relates to a cylindrical holder member for a bi-directional bulged rupture disc. The support body of the holder has a rim that supports the rupture disc with the concave surface of the disc facing the holder. The support body is provided with a unitary one-piece, centrally creased cutting element that is of generally V-shaped configuration in plan view. The cutting element has a pair of elongated converging leg components with each leg component being connected to and supported by the interior wall surface of the holder body, with each leg component having an arcuate cutting edge. The cutting edges of the leg components merge at the crease in the cutting element to define a central cutting edge peak section. The cutting element is positioned in the holder with the cutting edge peak section extending beyond the rim of the support body into the concave area of the disc. The V-shaped cutting element functions to provide for a fuller and more rapid opening of the disc upon reversal and engagement with the cutting element as compared with prior reverse buckling disc three-knife blade cutter units. The invention has especial utility in food, beverage, and pharmaceutical applications requiring sanitary pressure relief rupture disc structure.

A winder apparatus for winding webs of material into rolls includes a conveyor, and a winding turret with a plurality of rotatably driven winding spindles thereon. The winding turret indexes the winding spindles relative to the apparatus conveyor, with each spindle moved to a transfer position wherein a web of material is transferred from the conveyor onto the spindle to initiate roll formation. A rotatably driven transfer brush assembly is positionable in operative association with the conveyor and the spindle in the winding position to facilitate efficient and consistent transfer of a web from the conveyor onto the spindle for roll formation.

A clutch assembly for a UV module shutter, comprises a shutter shaft, a shutter drive arm, a clutch plate, at least one ball, a clutch thrust washer, and a spring assembly. The shutter shaft has a flange, the flange having a plurality of radially positioned flange detents. The shutter drive arm includes a drive pin, a drive arm cavity, and a receiver slot opening into the drive arm cavity, the drive pin disposable in a drive slot of a shutter end cap. The clutch plate may be disposed in the clutch plate cavity, may have a tab disposed in the receiver slot and a plurality of clutch plate detents. Each of the ball(s) may extend from one of the flange detents and may be partially disposable in one of the clutch plate detents. The spring assembly may exert a bias against the clutch plate and the thrust washer. The shutter shaft may extend through the shutter drive arm, the clutch plate, and the clutch thrust washer.

An apparatus and method for forming a rod member used to manufacture cigarette filter elements, involve an insertion device for inserting objects into and along the rod member formed from a continuous filter material supply. The insertion device includes an insertion member adjacent to the filter material supply and defining a series of receptacles about a periphery thereof. The insertion member rotates in a first rotational direction to receive the objects in the receptacles at a first rotational position and to insert the objects from the receptacles into the rod member at a second rotational position. A cleaning element is adjacent to the insertion member between the second and first rotational positions in the first rotational direction, and engages each of the receptacles upon rotation of the insertion member between the second and first rotational positions to remove residual material from the receptacles prior to the first rotational position.

Disclosed is apparatus for collecting a breath sample from a human subject, the apparatus comprising at least a mask portion which, in use, is positioned over the subject's mouth and nostrils so as to collect breath exhaled from the subject, the apparatus further comprising movement detection means for detecting movement of the mask portion, and an alarm signal generator, which alarm signal generator generates an alarm signal if the subject's head is outside a predetermined range of acceptable orientations during collection of a breath sample, but only after the subject's head has been outside the predetermined range of acceptable orientations for a defined or measurable period of time.

The invention includes an apparatus and method for selecting a desirable magnitude of a magnetic memory cell write current. The method includes determining a minimal magnitude of write current for writing to the magnetic memory cell, determining a maximal magnitude of write current for writing to the magnetic memory cell, and calculating the selected magnitude of magnetic memory cell write current based on the minimal magnitude of write current and the maximal magnitude of write current.
