Abstract: A silica hydrogel is contacted with a hydroxy-containing organic compound which is not completely miscible with water but which is sufficiently miscible with water so as to remove water, and thereafter the organic compound is removed by heating in an inert atmosphere prior to activation by heating in air. The heating in the inert atmosphere allows utilizing preferred organic compounds such as C<sub>5</sub> and C<sub>6</sub> alcohols which are desirable from a commercial standpoint because of the easy separation for recycle. In a preferred embodiment, the hydrogel is aged at a pH of 7 to 9 by means of either adding a base or by utilizing a chromium component containing bound nitrogen.

Abstract: PCT No. PCT/SE87/00616 Sec. 371 Date May 30, 1989 Sec. 102(e) Date May 30, 1989 PCT Filed Dec. 18, 1987 PCT Pub. No. WO88/04589 PCT Pub. Date Jun. 30, 1988.A method and an apparatus for cutting and deburring tubes is disclosed wherein the cutting apparatus includes a cutting device, a double-acting deburring device and two sets of separately actuated carrier jaws for clamping a base tube which is to be cut therein. At least one of the sets of jaws is movable toward and away from the other set of jaws. The method is achieved by feeding a base tube into the pair of separately actuated carrier jaws. The jaws are then closed to clamp the base tube on either side of the cutting device. After the base tube has been cut, the cutoff part of the tube is moved away a predetermined distance to enable the double-acting deburring device to be introduced between the cut ends of the base tube and cutoff part. When the deburring device is in place between the ends, the movement of the cutoff part of the tube is then reversed, whereby it contacts the deburring device which in turn contacts the base tube. Simultaneous deburring of both cut ends takes place, the jaws are unclamped and a new cycle is commenced.

Granted: 1998-04-14
Abstract: This invention relates to a radiating element, such as a microstrip antenna, having a low input impedance and being capable of allowing high RF power to be supplied to the radiating element. The radiating element incorporates impedance transformation capabilities by providing a dielectric member with an electrically conductive ground plane formed on one side of the dielectric member. A metal patch element is formed on the other side of the dielectric member and spaced from the ground plane by the dielectric member. The patch element is capable of radiating RF energy when coupled to a source of RF input energy applied thereto. An impedance transforming section is selectively located within the perimeter of the patch element to give a desired input impedance at a feedpoint of the impedance transformation section.

Title: An apparatus for separating sulphur and soil
Inventor: BRADLEY MAURICE ERNEST
IPC: B09C1/06
Filed: 1991-09-11
Granted: 1999-01-05
Abstract: An  apparatus  for  separating  sulphur  and  soil consisting of a liquid sulphur bath container having an upper compartment, and a lower compartment.   The upper compartment  has  a  bottom  sloping  downwardly  from  a peripheral top edge toward the lower compartment.   The upper compartment has a lower sidewall adjacent the lower compartment  with  a  liquid  aperture  whereby  liquids communicate between the upper compartment and the lower compartment.  A heating element is disposed in the upper compartment to maintain the temperature of a liquid sulphur bath.  Solid phase sulphur contaminants in soil are heated to liquid phase by the liquid sulphur bath.  As sulphur contaminated soil is placed into the liquid sulphur bath, a displacement of liquid sulphur occurs which results in a migration of liquid sulphur through the liquid aperture in the  lower  sidewall  into  the  lower  compartment  and ultimately through the outlet.  A belt conveyor extends parallel to the bottom of the upper compartment and through a slotted opening in the lower sidewall of the upper compartment  below the  liquid  aperture  into  the  lower compartment.   A layer of soil is carried by the belt conveyor  to  a  spillway  positioned  adjacent  the  top peripheral edge of the container.  The belt conveyor is of a filter material such that liquid sulphur passing through the  liquid aperture into the  lower compartment passes through the filter material of the belt conveyor thereby removing sediment from the liquid sulphur.
