Abstract:
A dynamic phase adjustment circuit that includes a multi-tap delay line that receives a clock input signal. The multi-tap delay line includes an initial portion that is adjustable, and final portion after the adjustable portion. A number of registers receive the same data. However, the clock signal that causes the registers to sample is received from a corresponding delay element in the final portion of the multi-tap delay line. An edge detect and data decision circuit receives the sampled data values from each of the registers. Sampling resolution is improved over the PLL-based dynamic phase adjustment circuit since the clock signal is delayed using delay elements, which can be made with relatively small delays. Furthermore, the circuit does not contain excessive circuit elements thereby allowing the dynamic phase adjustment circuit to be contained in a small area.

Abstract:
A roller structure for a rotary machine has a plate that is removably engagable with the outer casing of such rotary machines, a shaft portion attached to the plate and insertable through the outer casing, a bearing mounted for rotation upon the shaft portion, and a selected plurality of shims having different thicknesses engagable upon the shaft portion to adjust the position of the bearing with respect to an inner casing of the rotary machine.
Abstract:
Apparatus for establishing a "home" position for a load element driven axially along the lead screw. A position sensor includes a first sensor element attached for axial travel with the load element and a second sensor element attached for rotation with the lead screw. The pair of sensor elements is operatively aligned at a predetermined relative axial and rotational position establishing the "home" position.
Abstract:
An oral care composition having a first phase of clinically efficacious 2,4,4′-trichloro 2′-hydroxydiphenyl ether admixed in a first orally acceptable aqueous vehicle, and a second phase having a stannous salt (such as stannous fluoride) admixed in a second orally acceptable aqueous vehicle. The second phase has no less than 10 molar percent of soluble stannous ion respective to a mathematical sum of moles of the soluble stannous ion and moles of the stannous salt in the second phase. In one embodiment, the two phases are provided in a dual-tube toothpaste oral care kit.
Abstract:
Oral care compositions containing a stannous salt and sodium tripolyphosphate are provided where stannous tripolyphosphate ionic intermediates comprise less than about 1% of the compositions Tetrasodium pyrophosphate, a methylvinyl ether-maleic anhydride copolymer and/or a silica oral polishing agent may be added for further efficacy. In a single phase blend, the oral care composition may be effectively limited to comprise less than about 10% water. In a dual-phase blend a mixture having the stannous salt in a first phase and the sodium tripolyphosphate in a second phase may be generated from a dual chamber storage tube (with each phase provided from a separate chamber) immediately prior to dental care usage.
