Title: Apparatus and method for depositing particulate material in a composite substrate
Inventor: RIBBLE BRENDON F
IPC: A61F13/49
Filed: 1994-07-12
Abstract: An apparatus and method for forming a discrete layer of particulate material within a composite fibrous web includes a first forming chamber and a supplying mechanism for providing a flow of a selected fibrous material into the first forming chamber. A second forming chamber is selectively located within the first forming chamber to selectively divide the flow of fibrous material. A conveying mechanism transports a particulate material into the second forming chamber. A depositing mechanism is located within the second forming chamber to selectively dispense the particulate material. A foraminous forming layer is movably disposed within the first forming chamber and receives the fibrous material and the particulate material. As the foraminous forming layer moves, a first fibrous layer is formed on the foraminous forming layer, the particulate material is selectively deposited on the first fibrous layer, and a second fibrous layer is formed on the particulate material thereby providing the discrete layer of particulate material within the composite fibrous web. The depositing mechanism can be configured to dispense the particulate material in a selected pattern. The depositing mechanism can also be configured to intermittently dispense the particulate material at spaced apart locations along a length of the composite fibrous web.

Title: Coacervation processes
Inventor: MISTRY KISHOR K
IPC: B01J13/08
Filed: 1993-03-15
Abstract: The invention relates to processes for forming particles which have a core of core material within a shell of polymeric material that has been deposited by coacervation. According to the invention there is provided a dispersion of particles of core material in an aqueous solution of a pH-sensitive polymeric material at a pH  at which the polymeric material is soluble. The polymeric material is deposited as a shell around the core material by insolubilisation of the polymeric material caused by adjusting the pH of the solution to a pH at which the polymeric material is insoluble.  The adjustment of the pH is conducted at a rate that is sufficiently slow and homogeneous throughout the solution so that the polymeric material deposits substantially only as a substantially uniform coacervate around the individual core particles.

Title: Improved storage system for cryogenic fluids
Inventor: GUSTAFSON KEITH W
IPC: F02M37/00
Filed: 1994-09-26
Abstract: A relief valve is provided in the dip tube line that provides a fixed back pressure of 2-3 psi. When the economizer valve on the economizer circuit opens, the back pressure in the dip tube is the head pressure plus the 2-3 psi created by the relief valve. This pressure creates a path of least resistance through the economizer circuit such that the demand of product will draw gas from the gas head via the economizer line until the pressure falls below the valve set at the regulator. Once the pressure falls below the valve set at the regulator, the regulator closes the economizer circuit and liquid will be drawn through the dip tube. Because the relief valve prevents flow back into the tank, an orifice is provided to allow back flow of the cryogen from the withdrawal line to the tank once delivery of product is stopped.

Abstract: The invention relates to a process for removing elemental sulfur which is present in a gas in the form of vapor and/or entrained particles, in which process the gas to be treated is cooled. The gas to be treated is introduced into a heat exchanger at the lower end thereof and with the aid of the temperature and/or the flow velocity of the cooling medium it is ensured that the wall of the heat exchanger has a temperature below the solidification point of sulfur and above the dew point of water, if any, present in the gas. The deposited sulfur is removed under the influence of gravity countercurrent to the gas to be treated. <IMAGE>

The  station track has  an  incoming portion at the location where the car enters the station and an outgoing portion at a location where the car exits the station.  At least one turn-about wheel turns the conveying cable around to allow the one conveying cable to enter and exit the station.  A side  track  is  disposed  between  the  incoming  and outgoing portions of the station track, and a rotary switch,  disposed on the station track,  swivels to optionally direct the car to continue on the station track or to enter the side track.
