Granted: 2001-10-30
Abstract: A method and apparatus are provided for injecting sealant into a packing assembly chamber surrounding a valve stem 11 of a valve 2 without venting the pressure within the valve 2. A cylindrical body 60 is frictionally welded to the exterior of the valve 2 adjacent the packing assembly chamber. A drill bit is passed into the body 60 and through a set of packing seals 87. An opening is completed into the packing chamber. As the drill bit is withdrawn from the body 60, a second valve 70 is manually "closed" to isolate the packing chamber from the drill bit and prevent. the escape of pressurized fluid when the drill bit is removed from the seals 87. Thereafter, a device for injecting sealant is attached to the body 60 and the valve 70 is "opened" to allow the sealant to flow into the packing chamber.

Title: Cargo loading system
Inventor: RAITH DAVID
IPC: B65G65/32
Filed: 1993-04-07
Granted: 1998-02-03
Abstract: Chip- or plate-like pieces such as wood chips are tightly packed into a ship's hold or other cargo space by directing the material through a pipe to fall by gravity, the pipe guiding the material to rotating paddles.  The paddles engage the pieces of material and propel the pieces away from the paddles along a horizontal path.  The pieces are spread over a wider area, and are given time to fall flat, so the pieces land in the cargo space oriented for dense packing.  The paddles are connected to a center shaft and angle outward to connect to a support ring.          Material is dropped into the center of the support ring to be engaged by the paddles as the assembly rotates.  Material can be limited to the upper, faster, areas of the paddles by a frustoconical diverter disposed centrally of the paddles.  A choke can be used to provide a dense stream of pieces to the paddles; and, the choke may move the stream off center for uneven distribution.

Granted: 1996-12-10
Abstract: A  method   and  apparatus   for   non-contact determination  of  the  moisture  content  in  moving  or stationary mass  of  fibrous products such  as wood  is provided.      The  method  comprises  irradiation  of  a substance with infra-red radiation which is intense enough to  introduce  microstructural  modifications  of  the substance surface.  The moisture content of the substance is  determined  by  analyzing density  of  these  surface modifications.  It has been found, that an optical beam may be used in order to quantify the density of the surface modifications.  The surface is scanned with the optical beam two (2) times.  The first scanning is done prior to the infra-red irradiation; the second scanning is done following the infra-red irradiation.   The invented method  allows  for  non-contact,  rapid  and  continuous in-line measurements of the moisture content.

Abstract: Pressure-compensating pads such as seats or cushions used in wheelchairs, can be filled with a flowable, pressure-compensating composition comprising a major portion of silicone fluid, a minor portion of amide thickener which is essentially insoluble in said silicone fluid and microballoons. The resulting compositions are particularly characterized by their ability to flow in response to a continuously applied pressure, yet to maintain their shape and position in the absence of applied pressure, and are further characterized by stable viscosity at temperatures generally associated with the presence of the human body and excellent fire retardant properties. The composition may also contain flame-retardant.

Abstract: The direct conversion of methane to hythane,  an alternative fuel for internal combustion engines,  is effected  by  subjecting  methane  to  a controlled oxidation with water vapor at a temperature of about 400 to about 500°C and a pressure of about 1 to about 5 atmospheres,  in the presence of a catalyst comprising palladium or a binary alloy thereof with another metal selected  from  the  group  consisting  of  elements belonging to Group IB,  Group IIA,  Group VIII and the lanthanide series of the Periodic Table,  the catalyst being  supported  on  a  porous  carrier.  The  direct conversion of methane to hythane under conditions of low temperature and pressure in accordance with the present invention enables hythane to be produced not only economically and efficiently, but also at or near vehicle fueling sites, thereby eliminating the storage and transportation of dangerously reactive hydrogen for mixing with methane or natural gas.
