Title: Exhaust-control device for circuit interrupter
Inventor: SWANSON ROY T
IPC: H01H85/43
Filed: 1988-04-22
Granted: 1992-05-05
Abstract: ABSTRACT            An exhaust-control device is provided to absorb the energy of exhaust gases released during operation of a circuit-interrupting device such as a power fuse or an expulsion fuse.  The exhaust-control device includes  a first heat-absorbing medium through which the exhaust gases pass for reducing the temperature of the exhaust gases below a predeter-mined temperature.  The exhaust-control device further includes a second heat-absorbing medium for receiving the exhaust gases exiting from the first heat-absorbing medium.  The material, quantity, size distribution, and arrangement of the first heat-absorbing medium is selected so that the predetermined temperature of the exhaust gases does not cause signifi-cant melting of the second heat-absorbing medium that is utilized.  In a specific arrangement,  the first heat-absorbing medium is a section of ceramic pellets and the second heat-absorbing medium is a roll of woven copper mesh.

Abstract: L'invention concerne un procédé de cokéfaction de chargesd'hydrocarbures telles que produits lourds de distillation ou résidus. Elle concerne plus particulièrement l'étape subséquente de récupération du coke après qu'il se soit déposé dans le réacteur de cokéfaction. Ce procédé consiste à faire descendre dans le réacteur, à partir d'un tambour sur lequel il est enroulé, un tube flexible de résistance mécanique suffisante dont l'extrémité inférieure est pourvue de moyens d'éjection d'eau vers le bas et/ou latéralement et dont la descente est contrôlée par le dévidement du tambour. On fait passer de l'eau sous pression dans le tube et à travers les moyens d'éjection, dans la direction du coke et on évacue les morceaux de coke qui se sont détachés. Le tambour peut se déplacer latéralement de manière à venir se placer au-dessus de chacun des réacteurs à tour de rôle lorsque deux réacteurs ou plus sont utilisés.

Granted: 1992-09-01
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a method of attaching an optical fiber alignment ferrule to a connector body, the first end of which is lens-shaped.  The body has an indent-ed region in the second end thereof opposite the lens, the indented region being centered on the optical axis of the lens.  The body is mounted in a cavity in an an alignment fixture which also includes a bore that is aligned with the cavity.  The bore is so positioned that when a connector body is mounted in the cavity, the axis of the bore is coaxial with the optical axis of the lens.  A rigid align-ment rod is slidably mounted in the bore so that the rod is capable of only longitudinal movement along its axis. One end of the rod is inserted through the hole in a tubular ferrule.  The rod is advanced toward the connector body until the rod contacts the bottom of the indented region. The ferrule is moved along the rod until it contacts the second surface of the body.  The ferrule is then bonded to the body.

Title: Method of producing stainless molten steel by smelting reduction
Inventor: KAWAKAMI MASAHIRO
IPC: C22C38/18

Granted: 2000-03-07
Abstract: The invention is concerned with a method of producing stainless molten steel by smelting reduction in a smelting reduction furnace provided with a bottom tuyere, a side tuyere and a top lance having a first outlet and a second outlet. The method of the invention comprises the steps of a) reducing raw chromium ore in the furnace by use of carbonaceous material to produce chromium molten metal at the bottom of the furnace and having slag, above the molten metal; b) blowing CO and/or inert gas through the bottom tuyere into the molten metal to cause agitation thereof; c) blowing CO and/or inert gas through the side tuyere into the molten metal so as to contact the agitated molten metal; d) concurrently blowing decarburizing oxygen through the first outlet of the top lance into the molten metal and post-combustion oxygen through the second outlet of the top lance into the slag, so that the molten metal is decarburized; e) reducing chromium material by maintaining a ratio of post-combustion to more than 0.3; f) discharging the slag after completion of reduction; and g) after discharging of the slag, concurrently blowing a decarburizing oxygen diluted with an inert gas through one of the outlets of the top lance into the molten metal and blowing an inert gas through the bottom tuyere into the molten metal so as to agitate forcibly the molten metal. The invention enables one to carry out the smelting reduction at high treatment speed and the smelting reduction and decarburization in the same furnace.

Title: Bromoethylation of aromatic hydrocarbons
Inventor: KNESEL GEORGE A
IPC: B01J27/053
Filed: 1989-08-04
Granted: 1997-04-01
Abstract: An aromatic hydrocarbon is bromoethylated to a 1-bromo-1-arylethane with minimal co-formation of diaryl-alkane by-product by reacting it with hydrogen bromide and acetaldehyde at a temperature in the range of +10°C to -35°C in the presence of at least about one mol of hydro-gen sulfate per mol of the aromatic hydrocarbon and in the absence of more than  bout 15% by weight of water, based on the weight of the hydrogen sulfate.  The process is of particular advantage in the bromoethylation of the less reactive aromatic hydrocarbons, such as isobutylbenzene and other monoalkylaromatic hydrocarbons, which have previously yielded an undesirable amount of diarylalkane when bromoethylated with acetaldehyde.

Title: Anatomically contoured convoluted foam pad
Inventor: GILROY KEITH
IPC: A47C27/14
Filed: 1989-08-31
Granted: 1995-07-18
Abstract: A foam pad containing slits in its upper surface is disclosed.   In its preferred embodiment the pad is adapted to be positioned on a bed in a supporting relationship to a patient.  The pad has head and foot supporting sections, each in the form of a convoluted checkerboard pattern of rows  of peaks separated by depressions.   A torso supporting section is located between the head and foot supporting sections comprising substantially parallel ribs separated by substantially parallel valleys.  The slits are located on the torso supporting section, transverse to the ribs, forming a diamond-shaped  area.    Each  slit  varies  in  depth decreasing from the center of the pad towards the sides of the pad.  Additionally, the overall depth of the slits is progressively shallower towards the head and foot supporting sections of the pad.  In another embodiment, slits of the same configuration are used with a pad having a smooth upper surface which supports at least a portion of a body.  The configuration of the slits cause the pad to be softer permitting the bony prominences of the of the body in contact with the slits, to sink deeper into the pad than other portions of the body.   This substantially reduces the pressure placed on the skin covering  these  bony prominences  thereby helping  to prevent the formation of decubitus ulcers.

Abstract: Single or multiple blood plasma component concentrations are measured by a disposable stick having one or more blood plasma component reactive areas covered by a semipermeable membrane which is permeable by blood plasma or serum components and impermeable by blood cellular and particulate matter. A second overlay may be superposed with the semipermeable membrane over the reactive areas to receive a blood sample and meter and distribute that sample uniformly to the semipermeable membrane which in turn passes the plasma components uniformly to the reactive areas. The overlays are subsequently separable from the reactive area to remove the cellular components and particulate matter and expose the reactive areas for inspection by, for example, color comparison to standardized charts.
