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.

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.

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.
