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 ...

In the manufacture of PVC cellular plastic, a liquid plastic mixture is admixed with fibres in an amount of at most 1 percent by weight fibres, preferably carbon fibres having a length of about 1 cm, which fibres are distributed in the expanded cellular plastic isotropically with respect to both position and alignment. The cellular plastic is effective to dampen electromagnetic radiation within th...

A tap outlet (18) in a floor (12) of a vessel (10) has a shallow aperture (30) circumscribed by two drip lines (32, 34). The second drip line (34) circumscribes the first drip line (32) and is substantially coplanar with the first drip line. The two drip lines are connected one to the other by an annular hollow surface (38, 40).

Objects of thermoplastic polymer foam such as, e.g., sheeting of polyolefins such as polyethylene, are treated at elevated temperatures effective to rapidly purge the foam of a substantial portion of the residual blowing agent. Significant economies are achieved by reducing the amounts of residual blowing agents (such as flammable, toxic or environmentally hazardous gases) to levels presenting no ...

A cable television transaction terminal comprises a keyboard for entry of selection and field completion data and a teletext screen generator for actuating a visual display of teletext screens comprising selection items or completion fields. Each screen is uniquely identified and stored in terminal memory prior to display with an associated key template for defining selection and field completion ...

(57) In the manufacture of PVC cellular plastic, a liquid plastic mixture is admixed with fibres in an amount of at most 1 percent by weight fibres, preferably carbon fibres having a length of about I cm, which fibres are distributed in the expanded cellular plastic isotropically with respect to both position and alignment. The cellular plastic is effective to dampen electromagnetic radiation with...

DENTAL ADHESIVE COMPOSITION This invention provides dental adhesive compositions consisting essentially of (a) an aliphatic amine salt of a polymerizable phosphoric ester, as represented by the formula where R and R' are specific radicals; (b) at least one radical-polymerizable unsaturated monomer; and (c) a radical polymerization initiator. These compositions are useful in bonding living dental t...

Material and process for rectifying a bone defect by filling in with bone tissue using a bioreactive granulate inducing osteostimulation, the particles of this granulate being disintegrated from within, dissolved and replaced by bone tissue, the granulate containing 40 to 55 % of SiO2, 10 to 32 % of Na2O, 0 to 12 % P2O5 and 10 to 32 % of CaO, and having a particle size of between 280 and 425  mu m...

The fuel injection device for an internal combustion engine includes a fuel pressurisation chamber and a fuel chamber which are coupled to each other by a solenoid valve. The timing of fuel injection and the amount of fuel to be injected are controlled by selectively opening and closing the solenoid valve. Valve opening delay times of the solenoid valve are measured, and averaged when the rotation...

The fuel injection system has a reference mode operating during starting. This provides a programmed amount of fuel without any risk of excessive exhaust emission. The programmed mode operates until the processor detects normal running. The fuel injection operates via a solenoid valve (20) which opens during the pressure pulses of the mechanical fuel pump. The starting mode operates as a series of...
