Abstract: A new and improved composition and method of determining the specific gravity of an aqueous test sample. The method includes using a test device comprising a carrier matrix incorporating a reagent composition capable of interacting with an aqueous test sample to produce a visually or instrumentally detectable and measurable response that correlates to the specific gravity of the aqueous test sample. The new and improved reagent composition, comprising a molybdate-dye complex indicator, such as a molybdate-pyrocatechol violet complex; a protein, such as albumin; a chelating agent, like tartaric acid; and, if necessary, a suitable buffer, is incorporated into a carrier matrix, like filter paper, to provide increased sensitivity to test sample specifically gravity and improved color differen­tiation between test samples having different specific gravities, thereby affording a more accurate and trustworthy specific gravity assay of an aqueous test sample, such as urine.

Abstract: There are time-division multiplex communication systems in which digital signals which are asynchronous with the pulse frame and consist of successive blocks whose beginnings are marked with sync words are inserted into the pulse frame. The resulting jitter of the sync words ("waiting-time jitter") is reduced by a circuit which derives from the clock of the received sync words a sync signal (SY) that exhibits less jitter than the clock of the received sync words. According to the invention, the circuit contains a measuring device which measures the time intervals (N) between the sync words, a filter (F) which takes the average (N') of the time intervals (N), and a signal generator (S) which forms the sync signal (SY) from said average (N') in such a manner that the pulse period of the sync signal (SY) is equal to said average (N').

Abstract: A series of dual curing dental cements are disclosed which consist of powder and liquid components to be mixed within a preferred powder to liquid range by weight. Mixing is initiated immediately prior to usage following which the mixed material is applied to the tooth surface as required and cured within a few seconds by irradiation with high intensity visible light energy to a tough leathery consistency, thus permitting the bulk placement of other dental restoratives over it without disturbance. The second stage curing, which is chemically initiated, occurs much more slowly between the powder and the liquid and results in a fully set cement which is hard and rigid. 
     These cements are adhesive, both to prepared tooth structure and to composite dental restorative materials bulk placed over them. Thus, they combine the advantages of conventional dental glass ionomer cements with those of a first generation visible light cured cavity liner.

Abstract: A Class-A complementary metal oxide semi-conductor (CMOS) operational amplifier (2) is provided having an improved slew rate. The preferred embodiment of the invention utilizes a CMOS amplifier circuit (4, 12, 22, 32) and an external capacitor (40), which together exhibit relatively poor sourcing of current and hence a relatively low positive slew rate in response to an input signal being more positive than an output signal of the CMOS amplifier circuit (4, 12, 22, 32) by a relatively large amount. The disparity between the input and output signals defines an error signal. The present invention also includes a supplemental output stage (44) communicating with the amplifier circuitry and the external capacitor (40). The supplemental output stage (44) is activated in order to supply additional sourcing current, thereby increasing the positive slew rate, when a relatively large error signal is present and is de-activated otherwise.

Abstract: Implantable electrodes (16) for defibrillation are formed of pluralities of electrode segments (18,20,22). Each of the segments (18,20,22) is relatively long and narrow. The electrode segments (18,20,22) can be parallel and spaced apart from one another a distance (D) at least ten times the nominal width (W), with one end of each segment (18,20,22) mounted to a transverse distal portion (24) of an electrically conductive lead (26) coupling the electrode (16) to a defibrillation pulse generator. Alternatively, segments can branch or radiate outwardly from a common junction. In yet another arrangement, electrode segments are portions of a single conductive path at the distal end of a lead from a pulse generator, arranged in either a spiral configuration or a serpentine configuration which can align electrode segments side by side, parallel and spaced apart. The electrode segments can be formed of composite conductors in the form of titanium ribbons or wires with a sputtered outer layer of platinum, or a silver core in a stainless steel tube, with a platinum layer formed onto the tube. The electrodes are highly compliant yet can provide large effective areas for defibrillation, enabling a transthoracic pulsing arrangement of two electrodes on opposite sides of the heart, implanted subcutaneously outside of the thoracic region.

Abstract: The present invention provides a disk drive apparatus for use in computer systems and especially in computer systems where size and weight are of paramount concern, such as lap top computer systems. The preferred embodiment of the disk drive apparatus includes a 63.5mm (2.5") magnetic disk that preferably provides 20 to 40 megabytes of storage within a foot print area of approximately 71.1 mm (2.8 inches) by approximately 101.6mm (4.0 inches). Further, the disk drive apparatus possesses a height dimension of 16.0mm (0.630 inch) or less. This height dimension is achieved, in part, by providing a low profile spin motor to rotate the magnetic disk. The low profile spin motor uses high energy magnets that are preferably made of a material that includes a rare earth, such as neodymium or samarium. The disk drive apparatus also employs a rotary actuator having a voice coil assembly of reduced height that is achieved by using the housing as a flux return path for magnet fields produced by the voice coil assembly. The present invention also provides an improved ambient filter that reduces the penetration of ambient water vapour into the housing of the disk drive apparatus. An improved desiccant located, at least in part, within the housing is also provided by the present invention.. Additionally, the invention provides a flex circuit having a geometry that results in substantially zero torque applied to the rotary actuator. Also provided is a distributed frame apparatus that, besides connecting the housing to a printed circuit board, also provides side, top and/or bottom mounting capability and shock absorbing capability. The distributed frame also avoids the need for grounding.
