Title: Pop-up handle assembly
Inventor: LARSEN MARVIN L
IPC: E05B5/04
Filed: 1987-03-19
Granted: 1991-06-25
Abstract: ABSTRACT    A pop-up handle assembly having a base with a mounting panel and a tubular housing and a handle with a tubular stem axially movable within a hollow sleeve rotatable within the tubular housing. The handle mounts a key-plug which is depressable to release a lock pin carried by the tubular stem from engagement with a shoulder in the tubular housing whereby the handle pops-up to an operative position under the urging of a  spring.  The key-plug is rotatable between locked and unlocked positions and into an unlocked position can be depressed to release the handle for movement without the use of a key.  The handle assembly has provision for pop-up of the handle from the inner side thereof to free the handle for rotation regardless of whether the key-plug is either locked or unlocked.

Abstract: RESIN-IMMOBILIZED BIOCIDES               Abstract of the Disclosure For providing biocides in concentrated, immobilized form to an end use resin composition containing a primary thermoplastic resin with which the primary resin is incompatible at high concentrations, solid biocide resin concentrates are provided which immobilize high concentrations of biocide.  The solid biocide resin concentrates may contain an alloy of two thermoplastic resins, one of which is substantially identical to the primary resin and one of which enables incorporation and immobilization of high concentrations of biocide in the solid biocide resin concentrates.  The solid biocide resin concentrate may contain, in whole or in part, a thermoplastic copolymer having mer units such as are present in the primary resin in addition to dissimilar mer units which enhance compatibility of the biocide with the copolymer.  OBPA-containing solid resin concentrates for adding to an end use resin composition in which polyethylene is the primary resin may contain polyethylene plus a second thermoplastic resin in which OBPA is generally compatible and/or a copolymer containing both ethylene and acrylic acid mer units and/or a terpolymer containing ethylene, vinyl acetate and carbon monoxide mer units.  Ethylene/acrylic copolymers and ethylene/ vinyl acetate/carbon monoxide terpolymers are each useful for forming solid biocide resin concentrates that are miscible with a wide variety of thermoplastic resins.

Granted: 1995-01-10
Abstract: A magnetic disc apparatus wherein off-track quantities are stored with regard to reference servo tracks formed circularly in divided data areas on a magnetic disc and, at the time to displace a magnetic head, the head is shifted an extent of the stored off-track quantity after being once positioned by a head position detector.  Gradients of the off-track quantities to tracks at individual temperatures in the apparatus are previously stored and, after the actual temperature is detected by means of a temperature sensor, the off-track quantity relative to the reference servo track is corrected in accordance with the gradient of the off-track quantity to the relevant track at the detected temperature, whereby just tracking is achieved.  The magnetic head can be positioned exactly with respect to a desired data track while the head displacement time is shortened.  Furthermore, data can be written in the entire length of each circular data track to enhance the effi-ciency of utilizing the magnetic disc, and high-precision tracking is attainable with the off-track quantity reduced to zero in any data track.

Abstract: The method of manufacturing an absorbent pad for utilization as a diaper or an adult incontinent brief, wherein a pair of continuous bands of adhesive are applied to the backing sheet of the pad, prior to assembly thereof. The nozzles eject adhesive onto a moving web comprising the backing sheet.  The nozzles are shifted sideways during their extrusion of adhesive, from a first location to a second location, thus generating a pair of non-linear bands of adhesive on the backing sheet.  The nozzles are again shifted from their second location to their original first location upon receipt of proper signals from a control mechanism.  The elastic band is not shifted when the nozzles are, thus effectuating securement of the elastic bands only on the portions of the backing sheets where the adhesive was applied at the first location.

Abstract: The present invention relates to a method which may decarbu-rize high Cr molten metal for a short period of time under an atmospheric pressure, while checking loss of Cr by its oxidation.          A basic feature of the invention is to blow from the furnace top lance a decarburizing O2 diluted by an inert gas into the high Cr molten metal supported in a container as well as blow the inert gas from bottom tuyeres so as to forcibly agitate the molten metal.  Another feature of the invention is to control a slag amount during the above decarburizion blowing so as to check the Cr oxidation loss. A further object of the invention is to carry out a denitrification in the above decarburization, thereby to produce low N molten metal while checking the loss by Cr oxidat-ion.

Title: Codecs with suppression of multiple encoding/decodings across a connection
Inventor: GAY STEVEN LESLIE
IPC: H04B14/04
Filed: 1989-03-09
Granted: 1997-10-28
Abstract: In a private telecommunications network, a plurality of digital PBXs are interconnected via pairs of codecs. The codecs of each pair, or "tandem", are each operative to encode 64 kilobit/second (kbps) mu-law speech so as to compress it to 16 kbps speech for transmission to the other codec in the tandem.The latter is operative to thereafter decompress the 16 kbps speech back to 64 kbps. Each codec has a second mode of operation in which, rather than decode the encoded speech, it preserves the bits thereof in its own output signal. The codec transitions to this mode whenever it recognizes the presence of another codec on its high-bit-rate side of the connection. As a result, only one encoding/decoding cycle is performed across the connection, thereby minimizing the speech-coding-induced distortion and delay therein. The mechanism enabling a codec to communicate its presence to another codec on its high-bit-rate side of the connection is based on the transmission of predetermined synchronization patterns inserted in the signals it outputs in that direction. In a second embodiment, codecs of the above-described type are used in a cellular mobile radio telecommunications system.

Abstract: ABSTRACT    A speed reducer comprised of a casing obtained in a single block, which comprises a broad opening through which it is possible to mount the different internal elements, among which there is a flange which permits the assembly of a bottom shaft with its pinion and meshing, resting at one end of the bearings and at the other on a bridge.  It also includes some coaxial shafts resting on the flange and on bearings.  The shaft is the one that is coupled to the motor outlet, while the shaft protrudes through the opposite part and constitutes the structure for effecting the transmission. The special distribution of the described internal elements permits that none of the gearing is overhanging; in other words, all the shafts have two supports with bearing, determining a greater balance and greater resistance of the unit.

Title: Data demodulation system
Inventor: RIGGLE CHARLES M
IPC: G11B20/10
Filed: 1989-05-11
Granted: 1993-01-26
Abstract: (83-496) ABSTRACT      A data demodulator assigns a binary value to the signal recorded in a transition cell based on the amplitude of the signal in the transition cell, the amplitudes of the signal in adjacent transition cells and system experience in categorizing how recording non-linearities and system no se effect the signals.  The recorded analog signal in the transition cell for which a binary value is to be determined, and the recorded analog signal in a selected number of transition cells adjacent to that cell are each sampled a selected number of times.  The amplitude of each of the signal samples is then converted to a digital signal symbol.          Portions of the digital signal symbol are concatenated to form an interpretation vector.  The vector is then used to enter a stored look-up table, addressing a particular memory location, and the binary value stored in that location is assigned to the transition cell.  The look-up table is created based on system experience and the demodulating of known signals.  The assigned values for a number of cells may be combined to form a code word which may be decoded using soft decoding techniques.  Thus corrections may be made to the estimate assigned to a particular cell using parody checks of other known decoding techniques.
