Title: Absorbent composites and absorbent articles containing same
Inventor: BYERLY SHANNON KATHLEEN
IPC: A41B/
Filed: 1991-12-16
Granted: 2002-05-28
Abstract: Reducing leakage in disposable diapers having a relatively high loading of superabsorbent materials requires a proper balancing of three properties of the superabsorbent material: the total absorbent capacity, the resistance to deformation when partially saturated, and the ability to wick fluids away from the insult area.     Absorbent articles with superabsorbent material/fluff composites, which contain high loadings of superabsorbent material having the proper balance of properties, can be made to be substantially thinner while providing leakage performance equivalent to bulkier conventional articles containing greater amounts of fluff,

Title: Apparatus for measuring heating temperature in high electric field of microwaves
Inventor: KONDOH ISAO
IPC: G01J1/02
Filed: 1992-01-07
Granted: 1999-07-27
Abstract: A microwave heating apparatus comprises a heating chamber for supporting an object to be heated, a microwave generator for generating microwave energy inside the heating chamber to heat the object, and an infrared radiation thermometer disposed outside the heating chamber.          A probe is disposed inside the heating chamber; the probe being formed of a microwave transparent material.  A fiber cable has a first end connected to the probe and a second end connected to the thermometer.  A lens is fixed in the probe in alignment with the fiber cable, for collecting infrared rays radiated from the object to be heated in the heating chamber and for transmitting the collected infrared rays into the fiber cable.  The collected infrared rays are transmitted through the fiber cable to the thermometer disposed outside the heating chamber, so as to measure an infrared radiation temperature of the object.  Optionally, a purge gas supply source can be disposed outside the heating chamber, with a gas purge conduit connecting the purge gas supply source to the probe.  A purge gas channel formed in the probe and operably connected with the gas purge conduit can release purge gas from the supply source toward the object, so that infrared rays are collected by the lens, while water vapor and/or a decomposition gas generated from the object is removed by purge gas.

Abstract: A composite brake drum particularly adapted for motor vehicle applications.  The brake drum includes a reinforcement assembly embedded within the cylindrical portion of the drum.          The reinforcement assembly is preferably made from steel wire stock and includes a plurality of circular rings or loops spaced axially within the brake drum cylindrical portion.  Axially extending locator wires are mechanically fastened to the reinforcing loops and serve to locate the loops.  End portions on the locator wires contact only one of the mold halves forming the mold cavity and enable the device to be essentially self-locating without crossing the parting line of the mold.  The end portion of the locator wires contacting the radially outer side of the mold cavity is formed with a spring bar to enable the locator wires to move outward as the reinforcing loops are thermally expanded during the casting process.  By not crossing the parting line, the position of the loops is maintained within acceptable tolerance limits from the finished friction surface of the drum.  The composite brake drum is fabricated by pouring molten iron into the mold and then performing finish machining operations.

Abstract: A method is disclosed for extracting data words from a binary serial bit stream having a fixed bit rate and consisting of fixed length words of n bits each, where n is an integer, each word is preceded by a start bit and followed by one or more stop bits. First a predetermined identifiable,transition is detected in said bit stream preceding each data word. A clock signal (DCLK) consisting of n clock pulses is generated in response to each detection of the predetermined transition in coincidence with the bits the data word following the predetermined transition. A data ready signal (DR) is generated after the passage of n bits to delineate the word boundary, and the data words are extracted from the bit stream using the thus generated clock pulses and the data ready signal.

Abstract: A process and apparatus for prechilling tap water by using a heat exchanger to provide a path of flow for the warm tap water fed into an ice maker machine and another path for the cold waste water ejected by the machine by means of which heat can be transferred through walls separating the fluids. The prechilling is achieved by using an insulated, elongated casing having top and bottom ends forming there between a closed reservoir housing the heat exchanger made of copper tubing or the like. The heat exchanger is in the form of a coil followed by a substantially straight tube within and surrounded by the coil's turns. A heat-insulating hollow member, which is closed at one end, is spaced from the straight tube to be surrounded by the turns and to form between that hollow member and the straight tube an elongated chamber whose bottom is open to the interior of the reservoir.

Abstract: Une fixation pour planche à neige comprenant une base destinée à contenir le pied, un coussinet de cou-de-pied destiné a couvrir le haut du pied, un support arrière articulé destiné à couvrir l'arrière du talon et de la jambe. Le coussinet de coude-pied est relié a la base par des câbles de tension passant dans les cotés de la base et étant finalement attachés sur le support arrière. Le support arrière est maintenu à la verticale par un levier a ressort. Lorsque le levier est tiré, le support arrière peut se rabattre vers l'arrière, dégageant l'espace arrière et relâchant la tension dans les câbles, ce qui permet un accès facile du pied. Ramener le support arrière à la verticale a pour effet de rétablir la tension des câbles pour maintenir le pied fermement en place grâce aux effets combinés du support arrière et du coussinet de cou-de-pied. Lorsqu'un pied n'est pas dans la fixation, le support arrière peut se replier sur la base afin d'occuper moins d'espace de rangement.
