Abstract: TITLE            ELASTODYNAMIC TESTING OF ELONGATE COMPRESSIBLE MATERIAL                           INVENTORS     RAYMOND METCALFE RONALD C. WENSEL                            ABSTRACT         This invention provides non-destructive testing of elongate compressible materials, and particularly to determine the elastodynamic properties of a material, and/or to detect defects such as non-uniformities in resilience or hardness, subsurface as well as surface defects such as inclusions, voids, tears, and the like.        The material to be tested is passed between two rollers to compress the material under predetermined operating conditions of substantially constant roller spacing or substantially constant com-pression load.  Measurement of the load or the displacement for the selected operating condition of constant roller spacing or constant load, respectively, provides an indication of elastodynamic properties of the material.  Variations in the measured load or displacement can be utilized to detect defects in the material.        The invention has been found particularly suitable for the testing of material for seals, such as O-rings.

Title: Method and apparatus for extending fly section of crane boom
Inventor: GATTU NARAHARI
IPC: B66C23/68
Filed: 1987-03-06
Granted: 1993-01-12
Abstract: METHOD AND APPARATUS FOR EXTENDING     FLY SECTION OF CRANE BOOM                   Abstract of the Disclosure Method and apparatus for extending a fly section of a telescopic crane boom which fly section does not have its own power unit to effect extension or retraction.  The boom includes a base section, an inner powered section telescoping within the base section, an outer powered section telescoping within the inner section, and a non-self-powered fly section telescoping within the outer section.  To extend the fly section, a load pin connecting the fly section to the outer section is released using a hydraulic cylinder mounted to the base section.  The load pin is locked in the released position by a locking device.          The outer section is then extended, taking the fly section with it.  Upon full extension of the outer section, the inner end of the fly section is latched to the inner section or base section by latch pins actuated by a hydraulic cylinder.  The outer sec-tion is then retracted, exposing the fly section and unlocking the load pin from its released position.  The load pin then simply slides along the bottom of the fly section until, upon full retraction, the load pin snaps into a hole at the inner end of the fly section to prevent relative motion of the fly section and the outer section.  The fly section is then unlatched from the inner section or base section.  At this point the outer sec-tion and inner section may be independently operated, with the fly section in fully extended position.  The fly section is then retracted by basically reversing the procedure.  A circuit is also provided so as to prevent both the load pin and the latch pins from being disengaged simultaneously unless the fly section is fully retracted within the outer section.

Title: Apparatus for gauge distribution in plastic tubing
Inventor: PLANETA MIREK
IPC: B29C48/33
Filed: 1987-06-25
Granted: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE        The apparatus of the invention provides gauge distribution in extruded plastic tubing, so that a more uniform roll thereof is obtained.  The extruded plastic tube, usually blown to increase its diameter and decrease its wall thickness, is collapsed and passed through a diametrical slot in a rotor, which is rotated about a vertical axis so that any non-uniformity in wall thickness of the tube is distributed as much as possible around its periphery.  The upwardly-moving tube passes over a skew member which turns it to move horizontally. Two spaced parallel end rollers are provided between one end of the slot and the rotor periphery, and each engages the tube during a respective 180° of rotation to deliver the tube to a fixed roller on the apparatus frame from whence it passes to the storage roll.  Two deflection rollers are also provided on opposite sides of the slot, and each engages the tube in the rotation of the rotor close to zero and 360° to hold the tube away from the slot and ensure that it does not foul the portion of the tube emerging from the slot.  A dancer roll may be provided to maintain constant tension.  The tube engaging members may be rollers or hollow bars with air issuing apertures in the surfaces over which the tube passes to form a corresponding air cushion between the tube and the member surface.

Granted: 1992-04-21
Abstract: SEMICONDUCTOR DEVICE INCLUDING ALTERNATING ORDERED LAYERS           Abstract Semiconductor devices are described including a structure of alternating first and second layers of Group-IV materials which together form an ordered composite structure having a crystallographic unit cell which differs from the unit cells of both the first and second layer materials. Structures in which both first and second layers are not more than 8 atomic monolayers thick have properties (such as, e.g., electronic or optical properties) which are significantly different from those of previously known Group-IV semiconductor materials and structures. As a result, structures of the invention give rise to novel device applications. In the case of germanium and silicon layer materials, the number of monolayers in first and second layers strongly affects electroabsorption properties. A structure of alternating first layers of 4 atomic monolayers Ge and second layers of 4 atomic monolayers Si is of particular interest for photodetector use on account of strong optical absorption at wavelengths near 1.6 micrometer.

Granted: 1991-07-16
Abstract: ABSTRACT            Apparatus for distributing the processing of data across a plurality of loci of control which are connected by a mail system.  The apparatus includes a package which contains files of various types and a route specifying the order in which the package is to be circulated among the loci and the processing to be done at each locus.  Each locus includes programs executable by users which can manipulate the contents of the package.  The programs automatically take the type of file being manipulated into account.  The manipulations include modifying the unexecuted portion of the route.  Each locus further includes a process which executes the route as modified, a process which tracks the package and receives control commands, and a process which handles errors detected by the other components or by users.  The tracking processes maintain data bases for locating the package.  When a user or the error handling process enters a control command at one locus, the tracking process at that locus uses the data bases to locate the package and send the control command to the locus currently processing the package.  The route executing process checks with the tracking process and executes any control command before it sends the package to the next locus.

Granted: 1992-11-10
Abstract: ABSTRACT                    A novel assay method is suitable for detecting a polynucleotide in a liquid sample.  The method comprises the steps of:  (a) combining the sample with at least two different probes, being a first probe and a second probe, to form a reaction mixture, each probe comprising a single-stranded polynucleotide which contains a nucleotide sequence complementary to a portion of the target polynucleotide, the probes together forming hybrid molecules by complementary base pairing with the target polynucleotide, neither probe being affixed to a solid carrier, the probes do not hybridize with each other, and the second probe having a detectable label;               (b)  subsequently contacting the reaction mixture with a solid carrier which binds the first probe but not the second probe and not the target polynucleotide; and (c)  subsequently determining if any of the label is bound on the solid carrier.  The method combines the speed and reaction efficiency of solution hybridization assays, and ease of separation of solid carrier hybridization assays.  A kit for use with the above method is also disclosed.  The method and kit of the present invention are also suitable for diagnosis of genetic diseases, e.g. sickle cell anemia, and for cancer diagnosis. For example, the assay method can be used to detect a target polynucleotide in a sample which may also contain a standard polynucleotide, the nucleotide sequences of the two polynucleotides being substantially similar, the standard polynucleotide having a portion A and a portion B, the target polynucleotide having a portion A' and a portion B', the standard and target polynucleotides differing in at least one nucleotide which is located between portions A and B on the standard polynucleotide and between portions A' and B' on the target polynucleotide, the method comprising the steps of:              (a)  severing both the standard and target polynucleotides present into single-stranded segments, such that none of the segments of the standard polynucleotide contains both portions A and B, while at least one of the segments of the target polynucleotide contains both portions A' and B';              (b)  combining the treated sample from step (a) with at least two probes, being a first probe and a second probe, to form a reaction mixture, each probe comprising a single-stranded polynucleotide, the probes being unable to hybridize with each other, the first probe complementary base pairing with portion A, and with portion A', the second probe complementary base pairing with portion B, and with portion B', the two probes together forming hybrid molecules by complementary base pairing with the single-stranded segment of the target polynucleotide which contains both portions A' and B'; and (c)  subsequently determining the presence of hybrid molecules containing both of the probes.

Abstract: ABSTRACT           A method of speech signal processing is disclosed which does not require excessive computation and which operates at low bit rates.  The method comprises filtering blocks of digital samples of speech signals by a linear-prediction inverse filter followed by a shaping filter, the coefficients of which are chosen from a codebook of quantized filter coefficient vectors, to obtain a residual signal subdivided into vectors.  Each vector is classified by an index q depending on a zero-crossing frequen-cy and a r.m.s. value.  Each vector is then normalized first on the basis of a quantized r.m.s. value, and then on the basis of a vector of quantized short-term mean values;the mean-square error occuring in quantizing these vectors with vectors contained in a codebook and forming excitation waveforms is computed.  In this codebook the search is limited to a subset of vectors determined by index q and p of each short-term mean vector.  The coding signal consists of the index of the filter coefficient vector, of indices q, p, of the quantization index m of the r.m.s. value, and of the index of the vector of the excitation waveforms found to generate the minimum weighted mean-square error.
