Title: Heat treatment facility for synthetic vitreous silica bodies
Inventor: NICHOLSON ROBERT
IPC: C03B37/012
Filed: 1993-05-13
Abstract: An induction-heated furnace, suitable for heat treatment of synthetic silica bodies, under conditions of high purity, includes a tubular susceptor (1) disposed with its axis vertical and an induction coil (3) for raising the temperature of the susceptor. The susceptor is made from graphite and/or silicon carbide, and is enclosed within a vacuum envelope (2) made from vitreous silica or fused quartz, the envelope being surrounded by the induction coil which is liquid-cooled. The design is such that the vacuum envelope (2) operates at temperatures below those at which either devitrification or sagging of the envelope might occur even when the tubular susceptor (1) is heated to a temperature of 1700 ·C. Thus sintering of a porous synthetic silica body (9) can be carried out under atmospheric or reduced pressure, the furnace including a shaft (7) adapted to support the body to be heated and capable of rotation about and movement along said vertical axis of the tubular susceptor (1).

Title: Method for production of beach-land
Inventor: LENARD FRANK
IPC: E02B3/12
Filed: 1994-11-24
Abstract: Water permeable bags are filled up with sand and placed on the beach, at or near the water's edge, the bag being fabricated, preferably, from a water permeable non-rotting material such as woven plastic or synthetic strips or bands. These types of bags can be recycled from spent animal feed bags which are commonly available in the agricultural industry.  Particularly suitable are spent feed bags, particularly from hogs, chickens or the like, that are commonly available through animal feed suppliers as recycled feed bags.  Preferably, the bags are juxtaposed one against the other and placed with a longitudinal axis orthogonal to the water's edge and along the water's edge or at the water's edge. Bags may be placed on top of a lower row of bags so that an effective barrier is created that is about two bags in width high, or even more.  Wave action during storm conditions having entrained sand from the water body overflows the bags and the velocity of the wave is slowed in behind the barrier and beach accretion occurs.

Title: Improved venturi scrubber and method
Inventor: SCHWAB JAMES J
IPC: B01D47/10
Filed: 1993-06-22
Abstract: A venturi scrubbing system (50) optimized for removing the most optically active sized particles from a gaseous effluent stream is disclosed. Before entering the venturi the effluent stream is subcooled (20) to cause condensation of water vapor and other condensibles, thereby greatly reducing the volume of the effluent stream.
