A dental measurement instrument having a handle and a measuring gauge extending from one end of the handle. In one embodiment, the measuring gauge has at least two calibrated measurement shafts in fixed spatial relationship with each other, each shaft bearing a plurality of calibration indicia. The calibration indicia on the two shafts are correlated with each other in a specific predetermined mathematical relationship.

An aqueous glittering ink composition whose viscosity ranges from about 1,000 to about 10,000 mPas, (measured by an ELD-type viscometer: 3.degree. R 14 cone, 0.5 rpm, at the temperature of 20.degree. C.) comprising a. aluminum powder pigments whose median diameter is not less than about 15 .mu.m compounded with oleic acid and/or stearic acid; b. synthetic resin emulsions selected from acryl based synthetic resin emulsions, styrene-acryl based synthetic resin emulsions and vinyl acetate based syn...

An irrigation control system having a master control, a plurality of electrical components and at least two coupling devices for connecting one of the electrical components to the master control. The coupling device has a male connector housing and a female connector housing. Each connector housing has first and second ends, with the first ends connected to either the master control or the electrical components. The second end of the male connector housing has a male connector and the second end...

A user wearable device for tracking or reminding the user of time and/or numerical records. In the preferred embodiment, the device takes the form of an attractive bracelet. The bracelet is made of two sets of beads strung together to form the bracelet and at least one charm for removable placement between the beads. The first set of beads has numbers marked thereon while the second set of beads does not have any markings. The two sets of beads are placed in a predetermined alternate fashion alo...

A spinal surgical prosthesis such as an artificial disc having a pair of upper and lower plate members, a flexible disc interposes therebetween and a rigid collar made of a bio-compatible and bio-resorbable material surrounding the flexible disc between the upper and lower plate members. Prior to the resorption of the collar, the collar serves to provide stability to the flexible disc for enhancing osteo-integration of the prosthesis with adjacent vertebrae. Subsequent to the resorption of the r...

An improved air supported impact section for air supported belt conveyors that includes a cushioned pad incorporated into the plenum plate to cushion the impact form and minimize damage to the air supported belt conveyors.

A fluid dispenser includes a housing, a sleeve reservoir and a container. The housing has a nozzle for dispensing the fluid and contains a power source, an infrared sensor, an integrated circuit chip and a pump assembly. The pump assembly includes a motor, at least one gear, a pipe and a helical shaft positioned coaxially within the pipe. The helical shaft is driven rotatingly relative to the pipe. The sleeve reservoir has open upper and lower ends, overflow openings near the upper end and a bal...

A portable kaleidoscope device for viewing kaleidoscopic images of at least one imaging object is provided with a viewing assembly for viewing the imaging object, a fill chamber assembly, a main body connecting said viewing assembly to said fill chamber assembly, and illumination source or black light-generating illumination source disposed in the device for illuminating the imaging object with light of a selected wavelength.

The invention is directed to a scratch ink composition improved in erasability, hiding power and ease of use. The invention relates to a scratch ink composition comprising a flaky pigment having a particle size distribution (as determined with a laser diffraction particle size distribution analyzer) such that the integral fraction of particles not larger than 10 .mu.m in diameter is not more than 30%, a resin component, and a solvent.
