A gasket for a compressed gas cylinder arranged to operate with a gas cylinder having a neck with a top surface around a gas outlet and a side surface extending downwardly from the top surface. The gasket may include an upper portion arranged for positioning on the top surface of the cylinder and for making a seal with the top surface, and a lower portion extending downwardly from the upper portion and around the side surface of the neck of the cylinder, such that the lower portion is arranged to make a seal with the side surface of the gas cylinder. Face and gland seals may be established by the gasket with an opening that receives the gasket and an associated cylinder neck.

A battery pack for powering a cordless power tool. The battery pack includes at least one battery cell operable to supply a discharge current, a switch operable to control the discharge current and a protection device to protect the switch. The protection device is positioned such that the device absorbs a current traveling in a direction opposite to that of the discharge current supplied from the battery cell.

A temperature sensor, particularly a high-temperature sensor, is provided in which an MI line or a heat-decoupling wire is arranged between the measurement resistor (chip) and the supply-line cable. Springs are stuck on the strands of the MI line, whereby the contacting to the measurement resistor is realized, or the heat-decoupling wire is stretched on one side to the end facing the measurement resistor and is connected elastically on the other end to the supply-line cable.

In a magnetically-coupled liquid mixer of the type having a drive mount secured to and extending into a mixing vessel, an external first magnet array adjacent to the drive mount, a stub shaft extending from the drive mount into the vessel and having a first thrust bearing surface, and a driven portion rotatably-mounted on the stub shaft and having a second thrust bearing surface and a second magnet array, the improvement wherein the first and second arrays are positioned with respect to one another such that the first and second thrust bearing surfaces are spaced apart at least in the absence of above-threshold fluid dynamic thrust forces on the driven portion.

A tooth system (1) for a tool (2) for earth moving machinery (3) is disclosed, which tooth system is of the type embodying a holder (4) located on the tool and a front tooth portion (5) that is detachably arranged on and in relation to the holder, which tooth portion is in the form of a replaceable wear and / or replacement part designed for the actual earth moving (W) and embodies a rear leg and the holder embodies a cavity (14) designed to receive the leg in interaction with the tooth portion and thereby achieve a unified joint (A, B, C, D) for assimilation of occurring loads (Fs, Fc, Fp) via a predetermined connection geometry embodying special, opposite, mutually interacting contact surfaces (15) and, at least initially, clearance surfaces (16) that are arranged along the tooth portion and holder. Thus, in accordance with the present invention one has achieved an improved tooth system distinguished by the tooth leg and holder cavity, along at least a front part of said joint (A, B, C, D), to have a multi-armed, preferably cruciform, cross section comprising at least four projection arms (31, 32, 33, 34) and at least four grooves (24, 28, 29, 30) each that interact with each projecting arm, respectively, which projection arms comprise an, essentially, vertically arranged, upper arm (31), an, essentially vertically arranged, lower heel (34) and two, essentially horizontally and laterally arranged, wing portions (32, 33), wherein a tensioning device (41) is arranged in the rear part (19) of the cavity in order to achieve adjustable tensioning that tightens the tooth portion in relation to the holder, essentially axially along the axial symmetry axis Y of the cavity.
