Granted: 1990-12-18
Abstract: ARTIFICIAL URETHANE ROCK AND METHOD FOR MOULDING          ABSTRACT OF THE INVENTION     A method for producing simulated rocks by spraying a high density polyurethane elastomer in a flexible mold. The method comprising reproducing a rock in molded form, not limited in size. A flexible mold is prepared by applying numerous coats of latex rubber upon the rock exterior in combination with a fabric embedded within the rubber latex layers. A supporting cradle for the latex mold is produced by spraying a low density urethane foam composition over the latex mold. The mold and cradle are stripped from the rock and are sprayed with a two component structural urethane system employing an isocyanate  component and a polyol component with appropriate catalysts, fillers and additives. The structural urethane elastomer is built up to substantial thickness to provide a strong load bearing polyurethane molded rock simulating the original rock surface with curing taking place in a matter of seconds or minutes.          After cooling, the molded urethane rock is removed and the mold may be reused for repeated molding operations.

Title: Process and apparatus for the intermittent straightening of wire
Inventor: DENZLER EMIL
IPC: B21F1/02
Filed: 1988-09-20
Granted: 1992-12-08
Abstract: Abstract of the Disclosure The intermittent straightening of the wire is carried out by means of a fixedly supported straightening rotor, the straightening blocks of which radially deflect the wire advanced by conveying means.  The mass moment of inertia of the straightening rotor is dimensioned to be so small that the straightening rotor can be decelerated and accelerated at least approximately within the same time period as the wire by the conveying means.  For cutting the length, the straightening rotor is braked in synchronism with the wire and thereafter again accelerated.  Thereby, a perfect wire quality is achieved, in particular a uniform elongation approximately constant over the entire length of the wire, without having to move the cutting device at the high wire feeding speed, or without having to move the straightening rotor axially or the straightening blocks radially, in order to avoid heating up and damaging of the arrested wire by the further operating straightening rotor. Different straightening rotors are utilized for different wire types, these rotors being easily exchangeable with their bearings.

Inventor: BLATT JOEL M
IPC: C12Q1/54
Filed: 1988-12-13
Granted: 1993-09-21
Abstract: ABSTRACT OF THE DISCLOSURE An analytical method and test composition for determining whether an analyte is present in a test sample at a predetermined concentration level by measuring or observing a preselected level of indicator response, e.g., color generation. A subtractive reaction is carried out on the test sample prior to the indicator reaction in order to stoichiometrically and specifically consume a predetermined amount of analyte. The resulting indicator reaction generates the preselected level of indicator response only if the analyte is present at the predetermined concentration level or greater. The subtractive reaction is enzymatically specific for the analyte in the reaction mixture and the amount of analyte consumed can be closely controlled by the amount of a regulating coreactant present at initiation. The method enables the determination of analyte without the need for standards or comparators, e.g., color charts, and therefore is self-indicating. In another embodiment, there is provided a method and test composition for improving an otherwise suboptimal assay response due to oversaturation of the response, e.g., color, generated by an indicator reaction.

Title: Servo pattern writing method for a disk storage device
Inventor: MINE SHINGI
IPC: G11B21/08
Filed: 1989-02-03
Granted: 1993-05-04
Abstract: ABSTRACT    The present disclosure teaches a method of writing servo patterns for increased productivity.  The process for writing servo patterns is divided into a pre-operation carried out before disks are installed into a disk device (fixed to the spindle shaft) and a post-operation that is carried out after the installation.  In the pre-operation, patterns written on the recording surface of the disk are two base patterns, namely, (a) a first base pattern arranged on each track center along one radial direction of the disk and (b) a second base pattern arranged along the radial direction at each position corresponding to the position of the sector in a substantially continuous fashion.  Then, the disks are assembled or installed into the disk device together with blank disks.  In the post-operation, the servo patterns are written based on the first and second base patterns.  Here, the expression "substantially continuous fashion" also includes the case where the number of discontinuous portions is smaller than that of the first base pattern even if some discontinuous portions are present in the base pattern, besides the case where the base pattern is completely continuous along the radial direction.
