Title: Process for the production of storage-proof aqueous sodium peroxomonosulphate solutions
Inventor: BERTSCH-FRANK BIRGIT
IPC: C01B15/08
Filed: 1991-06-28
Abstract: ABSTRACT OF THE DISCLOSURE            Peroxomonosulphate solutions known heretofore have an unsatisfactory storage stability and/or can be used in application technology only with limitations.  According to the present invention storage-proof aqueous sodium peroxomonosulphate solutions containing 5 to 50% by weight of NaHSO5 can be produced economically by partial neutralization of a sulphuric acid and solutions containing Caro's acid when this kind of H2SO4- and H2SO5- containing solution that contains less than 3 parts by weight of hydrogen peroxide per 100 parts by weight of Caro's acid and when the partial neutralization is carried out up to an equivalent ratio of total SO3 to sodium ions in the range of 1:1 to 1:1.3 and the solution is diluted or concentrated as required.

Title: Biologically active reagent, analytical element and methods for use of the reagent
Inventor: SUTTON RICHARD C
IPC: G01N31/22
Filed: 1991-07-03
Abstract: BIOLOGICALLY ACTIVE REAGENT, ANALYTICAL ELEMENT AND METHODS FOR USE OF THE REAGENT     Abstract of the Disclosure Biologically active reagents are prepared from particles of copolymers having polyoxyalkylene side chains, each of which side chains has a molecular weight of at least about 88.  The reagents are prepared by covalently attaching biologically active substances, for example antibodies, to the particles, directly or indirectly through reactive groups on the particle surface.  These reagents are used to advantage in analytical elements and methods for the detection of specific binding ligands (such as immunological species) and immunoassays, and in purification methods as affinity chromatography reagents.  Adsorption of undesirable proteins on the particles of the reagents was considerably reduced because of the specific composition of the particles.

Abstract: ABSTRACT The invention relates to a method of extracting gold from a gold-containing material. The invention provides a process of extracting precious metals from a precious metal-containing material comprising mixing the material in a finely-divided state with an alkaline cyanide solution to form a mixture and recovering the metal from solution by known methods characterized in that said process is carried out in the presence of peroxymonosulfuric acid or salt thereof and, where necessary, adding oxygen or a source thereof to said mixture to provide a dissolved oxygen level of at least about 6ppm. In a preferred embodiment the process is used in conjunction with a carbon-in-pulp plant. In the preferred process ore slurry 2 is passed through a valve means 3a to a wood screen 5 via line 4a. The slurry is separated from waste wood splinters 5a under gravity to a reservoir 6 where it is combined with an alkaline cyanide solution 7 introduced via line 4b and metering pump 8a. The slurry mixture is then introduced into a first leach tank 9a via line 4c, metering pump 8b and valve means 3b. The slurry is then agitated using an agitated drive 11a in the presence of a triple salt which has been introduced via line 4d, metering pump 8c and valve means 3c and also in the presence of activated carbon 12 which can be introduced into any of the tanks, typically 9f and returned into the previous leach tanks and ultimately tank 9a via lines 4e to 4i and pumps 8d to 8h, The mixture is then passed through self cleaning carbon screen 13a to remove loaded carbon 14 to a second leach tank 9b where it is agitated by agitated drive 11b. The mixture is then passed through a second carbon cleaning screen 13b to a third leach tank 9c and subsequently through tanks 9d to 9f, Slurry is also returned into the previous tanks via lines 4e to 4i and pumps 8d to 8h. Air or oxygen can also be introduced into any of the tanks typically tanks 9c or 9d. The triple salt may also be added to any one of tanks 9b to 9f via valve means 3d to 3h. After the slurry/carbon mixture has proceeded through all the tanks, carbon fines 15a are removed using a carbon fine screen 15 to give an end solution 16 which is separated from the tailings 17 by metering pump 8i and valve means 3i. The end solution 16 is then extracted for gold using known methods (Figure 1) WP0254M.DOC
Patent CA-2049190-A1 (CA)
Inventor: KNOTT JACK E
IPC: B32B27/18
Filed: 1991-08-14
Abstract: ABSTRACT  A starch filled, coextruded degradable polyethylene film includes a starch filled inner layer positioned between two outer layers that contain a prodegradant.          The outer layers of the film, which contain no starch, enable the film to retain desirable physical properties similar to conventional polyethylene film.  The prodegradant causes the outer layers of the film to degrade under appropriate conditions exposing the starch filled inner layer.  The starch in the inner layer then serves as a source of nutrients for microorganisms which consume starch, leaving a porous structure that is vulnerable to oxidation, hydrolysis, direct enzyme action or combinations of these processes.

Abstract: Abstract of the Disclosure A temperature-controlled environmental chamber includes a resistance heater powered through a first solid state relay and a refrigeration unit including an electrically powered thermally controlled suction throttling valve connected in the refrigerant line between the evaporator and the inlet of the compressor, and including a bimetal motor and a heating element therefor powered through a second solid state relay.  A thermostat senses the temperature in the chamber and compares it to a set point temperature and outputs a pulse-width modulated control signal indicative of the difference between the two temperatures.  The control signal directly controls the heater relays for substantially continuous variation of the heater between minimum and maximum heating conditions.  The control signal also directly controls the throttling valve relay by controlling the power to its heating element for substantially continuous variation of the valve between maximum and minimum cooling conditions, so that the amount of cooling provided is inversely proportional to the amount of heating provided.
