A novel tensioner for use with flexible drives, such as serpentine accessory belts on automobiles includes a tensioner arm to spindle pivot design which employs a frustoconical bushing between an inner pivot surface of the tensioner arm and a spindle shaft. The frustoconical design of the bushing resists off axis movement of the tensioner arm and a wear take up mechanism biases the bushing into contact with the inner pivot surface to compensate for normal wear of the bushing and/or pivot surface. A thrust plate is mounted to the end of the spindle shaft and rides in a thrust washer, the thrust plate and thrust washer being held captive in the tensioner arm such that the tensioner arm can pivot about the bushing and the spindle and the thrust plate and thrust washer assist in inhibiting off-axis movement of the tensioner arm. In one embodiment, the biasing force which biases the bushing against the inner pivot surface of the tensioner arm can be varied to change the amount of dampening of the tensioner.

A dispensing device for viscous pastes, for multiple users, which deploys a plurality of color coded caps for their personal identification and use. The device is screwed onto a squeezable tube of paste (for example, toothpaste), and, as the tube is squeezed, the paste flows through the device, past caps in a "closed" position, and out of a desired number of caps in an "open" position, in order to dispense paste. The caps' conduits are of a predetermined circumference for dispensing the desired amount of the paste. A smaller circumference is more economical, as less paste would flow out of such a conduit. This would be especially useful when the users are children. Threaded or friction-fitting cap tops may be attached to the device. If attached by friction-fitting, the cap tops form orbital lips to ensure a tight frictional fit to the cap necks. Connecting bands link the dispensing cap tops to the device, so that the tops won't be lost. The device can be attached to various sized squeezable tubes by a threaded connector cap. The diameter and thread gauge of the connector cap is of a predetermined diameter and gauge, for matching diameters and thread gauges of squeezable tubes. The device is preferably composed of plastic material, which is easily cleanable, sanitary, as well as inexpensive to manufacture.
