The nonmetal belly section is overlaid and connected on at least a part of the skirt section or the entire skirt section, whereby the nonmetal belly section is connected with subsidiary shoulder section to form an integrated structure.

Abstract: A circuit breaker and/or earthing switch are disclosed wherein a rotatable spindle nut, which is mounted in a spindle housing, displaces a spindle in a translatory manner, thus displacing contact elements of the switching device. The spindle actuates a contact pin that is configured in a contact carrier by a connection yoke that is common to all phases or poles and an isolating bar for each phase or pole.

Abstract: A medical specimen tote assembly containing a coolant. The assembly is configured with wells sized to individually receive and safely support one or more specimen tubes. At least one of the components of the assembly or a portion thereof is formed to contain a temperature-sensitive material that causes the component or portion to change color when a preselected temperature is exceeded. More preferably, the material causes a color change to occur at or near freezing, so as to indicate if the temperature of the component, and therefore specimens contained by the assembly, is near 0° C. or slightly higher.

Abstract: A battery switch has two identical, nested terminals separated by an insulator and having aligned openings for receiving a connecting bolt. The bolt when installed in the openings provides electrical connection between the terminals. Each terminal has a lug for connection to a battery cable or post, an extension portion attached to the lug and a receptacle for receiving the extension portion of the other terminal. The extension is offset from a central plane so the two terminals fit together along the central plane in a low profile configuration. The interfitting extensions and receptacles lock the terminals together.

Abstract: A screw operated electrical contact device having at least one pair of electrical conductors disposed on and projecting evenly above a dielectric surface, an insulation gap separating said conductors from each other, a nut attached to or part of the dielectric surface, having a center axis perpendicular to the surface aligned with the gap, a screw in threaded engagement with the nut, the screw being adapted to be moved along the length of the axis as it is rotated about the axis in the nut, and a contact dimensioned to bridge the gap, mounted fixedly and insulatingly in the screw, adapted to connect the conductors electrically together by exerting simultaneous pressure on both of them as a result of advancement of the contact toward the surface caused by the screw being rotated about the axis.

Abstract: A single pole, single throw switch for flashlights and other low amperage circuits is enclosed in a dielectric housing having an electric circuit contact fixed therein, the switch being selectively actuable by moving a threaded portion of a first electrode into and out of a complementarily threaded portion of a second electrode. Relative motion of the electrodes is achieved by manually rotating a cap-like part of the housing to which the first electrode is fixed. Voltages that can be accommodated by the switch are limited by the associated I.sup.2 R effects of contact resistance during switch actuation. Various components of the switch are fixed in the dielectric housing by friction, tongue and groove fasteners, and screws to facilitate servicing and repair.
