Title: Process for removing heavy metal ions and arsenic from wet-processed phosphoric acid
Inventor: SCHIMMEL GUENTHER
IPC: C01G21/00
Filed: 1983-07-20
Abstract: The disclosure relates to a process for removing heavy metal ions and arsenic from wet-processed phosphoric acid, wherein the crude wet-processed phosphoric acid is treated at temperatures between 10 DEG  and 100 DEG  C. initially with a diorganyldithiosphosphoric acid ester and then with an adsorbent, and the phoshoric acid so purified is separated from the ester and adsorbent. More particularly, the wet-processed phosphoric acid is treated with the diorganyldithiophosphoric acid ester at temperatures higher than 50 DEG  C. and with the adsorbent at temperatures lower than 50 DEG  C.

Title: A method and apparatus for the compensation of echo signals
Inventor: SCHOLLMEIER GERO
IPC: H04B3/23
Filed: 1984-07-27
Abstract: For the compensation of echo signals occuring in the course of the duplex transmission of digital signals by the dual channel system in signal transmission equipment provided with an echo compensator, the equipment is designed so that the clock pulses emitted by a timing generator for the transmission of the digital signals can be shifted in phase by predetermined phase grid steps. When a change in the phase position of the clock pulses takes place within one phase grid step, correction signals are generated, with the phase position that has been accurately set in each case being maintained. These correction signals are subtracted, together with the compensation signals emitted by the echo compensator for the compensation of the echo signals, from the digital signals received together with the echo signals.

Title: Method of making double walled tubular thermal protective coverings
Inventor: WALLACE VOLNEY
IPC: B29D23/00
Filed: 1985-02-26
Abstract: A process or method for making a unique, double walled, tubular device which is divided into a plurality of substantially vertically extending compartments (42) which are adapted to be filled with water. The double walled, tubular device is made from first and second sheets (11 and 16) of thermoplastic material in which each sheet (11 and 16) has been folded back over itself along its longitudinal dimension. Each sheet (11 and 16) is then subjected to heat sealing treatments in which weld lines (41) are formed in the sheets (11 and 16) thereby forming the vertically extending compartments (42) in each sheet (11 and 16). The first and second sheets (11 and 16) are then superimposed one over the other and mutually respective pairs of additional welded lines (40) are formed so as to seal or weld the double layers of the two sheets (11 and 16) together at spaced positions along the longitudinal length of the superimposed sheets (11 and 16). Each of the weldlines (40) of mutually respective pairs thereof are closely spaced, side-by-side of each other. The respective pairs of weld lines (40) are spaced from other pairs such that a plurality of compartments (42) are included in each of the sheets (11 and 16) between the pairs of weld lines (40). The sheets (11 and 16) are cut transversely of their longitudinal dimension between each of the weld lines (40) in the respective pair of weld lines (40) to produce individual units of the unique, double walled, tubular device of the invention.

Title: Method of manufacturing lactulose
Inventor: DORSCHEID MICHAEL
IPC: C07H3/04
Filed: 1989-12-18
Abstract: For the manufacture of lactulose, an alkaline aqueous solution of lactose and borax is prepared and heated at a temperature above 80 DEG C. The lactulose is separated from the resulting conversion products. Apart from the borox, no alkalising material is added to the solution. The conversion is carried out at pH 8.3. In order to maintain the sodium ions in the production cycle, the borox may be manufactured in an aqueous solution of boric acid and already simultaneously with the lactose, while the sodium ions are transferred from the solution of the conversion products in the solution of the boric acid by electrodialysis. Alternatively the sodium ions may also be removed from the solution of the conversion products as readily as possible by means of a weakly acid ion exchanger and only thereafter by means of a more strongly acid ion exchanger. The weakly acid ion exchanger is regenerated with boric acid so that borax is formed again.

Title: Process for Reclaimimg Wafer Substrates
Inventor: LEWIS DAVID JOHN
IPC: B24B37/08
Filed: 2000-11-11
Granted: 2005-01-05
Abstract: A process of reclaiming a semiconductor wafer 10 comprises the steps of a) removing films of foreign matter from the surface of the wafer 10 by etching, b) polishing opposite sides of the wafer 10 between contra-rotating polishing means 26,28 to remove doped and diffused regions in the surface of the wafer substrate, c) rendering matt at least a portion of one only of the polished major surfaces of the wafer, d) cleaning the major surfaces of the wafer; and e) drying the wafer.  The wafer is not damaged because no abrasive grinding is used to remove the doped and diffused regions and the step of rendering matt enables the wafers to be subsequently processed using handling and processing apparatus which relies on a difference in finish to determine the correct side of the wafer to be processed.

Title: Examining a diamond
Inventor: LAWSON SIMON CRAIG
IPC: G01N1/00
Filed: 2002-09-12
Granted: 2005-05-18
Abstract: In order to determine whether a blue-to-green diamond (1) has been artificially irradiated or ion bombarded to change its colour, it is irradiated with light of 633 nm wavelength in order to stimulate the emission of luminescence, and luminescence from about 680 to about 800 nm is detected using a confocal microscope (3) and a spectrometer (8) as the focal plane (9) is scanned vertically through the diamond (1). A rapid decrease in luminescence with increase in depth indicates natural irradiation whilst a more rapid decrease indicates ion bombardment. Alternatively, in order to determine whether a diamond (1) is a natural/synthetic doublet, it is irradiated with radiation of 325 nm wavelength in order to stimulate the emission of luminescence, and luminescence from 330 to 450 nm is detected. An abrupt change in luminescence with increase in depth indicates that the diamond is a natural/synthetic doublet.

Abstract: An automated cleaning system, where dairy cows pass through a foot bath region. The foot bath is periodically changed by implementing an agitation phase where high velocity water jets agitate the waste material in the foot bath and causes these to be discharged, followed by a drain phase where the liquid flows out an outlet. Then, a flushing phase removes the further debris, with the foot bath then being refilled with water and chemical disinfecting liquid for a subsequent cycle where another group of cows would pass through the foot bath region.
