A dental floss holder is in the form of a box (20) with a drawer (22) in it. The bottom of the drawer includes a hub (38) which is spring biased to push a bobbin (24) mounted thereon toward an opposite side of the box. The bias is such that the bobbin drags with a predetermined force on an opposite side of the box to maintain tension in the floss. A result is that the bobbin does not unwind while ...

The dispenser comprises a four-legged wooden block 9 mounting a spindle 4 about which a turntable, for supporting a wool cone, may be operated. The spindle carries a safety screw 1, and a disc 2 to prevent cone wobble. The block carries guide 8 for wool running from the cone. A large or small turntable may be fitted.

Acquisition of CT transmission data and omission data is achieved with the same scanner. Because the transmission and emission date sets are spatially registered, the map of attenuation coefficients described by the reconstructed transmission images can be used for generating a mathematically correct matrix for correction of sequentially or simultaneously aquired SPECT imaging data. The imaging de...

A slip of the driven wheels is converged by causing the torque generated by the engine to be reduced and applying braking force when a slip of the driven wheel becomes large during accelerating. Control of the application of the braking force to the left-hand and right-hand driven wheels is made individually and separately from each other. When such an incident occurs as causing no normal control ...

A traction control system for an automotive vehicle is responsive to an excessive magnitude of wheel slippage to lower driving torque supplied to driving wheels (14) for resuming sufficient level of tire/road traction. The traction control system includes a catalyzer temperature sensor (20) for monitoring a catalyzer in exhaust system of an automotive vehicle, to produce a catalyzer temperature in...
