Title: Method and apparatus for automatically testing the antibiotic sensitivity of a paraffinophilic microorganism
Inventor: FELDER MITCHELL S
IPC: C12Q1/18
Filed: 1996-09-10
Abstract: A method of automatically testing the sensitivity of a paraffinophilic microorganism to different antimicrobial agents and concentrations thereof includes a plurality of receptacles (2-22) each containing an amount of liquid medium, and antimicrobial agent to be tested and the microorganism to be tested. A paraffin containing slide (32-52) is placed in each receptacle (222) after which incubation is effected. A light scatter sensor (62) is employed to automatically and sequentially monitor the extent of microorganism growth on the slides (32-52) and the growth of each slide is employed to determine which antimicrobial agent and which concentration is effective to resist growth of the paraffinophilic microorganism. The slides (32-52) are moved sequentially in operative relationship with the light scatter sensor (62) while resisting rotational movement of the slides. Positive and negative control slides are preferably employed as is a computer (64) in receiving and processing the results of the slide testing. Related apparatus is disclosed.

Patent CA-2237918-A1 (CA)
Inventor: JENNINGS STUART R
IPC: B09C1/00
Filed: 1998-05-19
Abstract: Mine tailings responsible for widespread water and soil degradation are an environmental problem due to the presence of metal sulfides, primarily pyrite, and elevated heavy metal and concentrations, and are often incapable of supporting plants because of salt toxicities, poor texture, and nutrient deficiencies.  Upon exposure to the atmosphere, residual pyrite in tailings oxidizes and generates acid. Once acid is generated, heavy metals present in the tailings are mobilized and released into the environment. Cleaning or reprocessing tailings is used to remove residual pyrite and heavy metals. Successful mineral separation resulted in a small amount of metal sulfide concentrate and a large volume of reprocessed tailings that had a low metal sulfide content. Total metal concentrations were reduced in the cleaned material and elevated in the metal sulfide concentrate when compared to the original, uncleaned tailings.

Inventor: VOLKOVITSKY PETER
IPC: G01N9/24
Filed: 1997-02-07
Abstract: A Multiphoton Densitometer (MP-Densitometer) for remote density measurement uses special multiphoton sources with very low, licen se-exempt activity to measure the density of samples. For gas/oil/water mixture inside 3 inch steel pipes, the measurement precision, using a 2 microCi source, is substantially equivalent to that obtained by a prior-art gamma densitometer using a 30 milliCi source. Using a 1 microCi source the MP Densitometer measures the density, with uncertainty less than 1 %, of fluids inside pipes with a range of diameters up to 10 inches. The invention achieves very low background (orders of magnitude lower than for prior-art gamma densitometers) through selection of densitometer elements, geometry, electronics, and software.  Reduction of system uncertainties, a temperature compensation scheme, active temperature regulation, real-time statistical analysis, and smoothing of the output signal allowed the elimination of temperature effects and pile-up artifacts. With a very low activity source, the MP-Densitometer has an accuracy in density measurements of 1 % for oil/water laminar flow. The uncertainty is 0.5 % for longer measurement tim es on the order of a few minutes.

Title: Process and apparatus for producing metal from metal ores
Inventor: VOSS MANFRED
IPC: C21B5/02
Filed: 1999-02-12
Abstract: The invention concerns a process and en apparatus for producing metal from metal ores, in particular crude or pig iron from iron ore, in which the ore which contains metal oxides is brought into reaction contact with a reducing gas which contains carbon and/or hydrogen (and possibly compounds thereof) and which was previously obtained from solid, carbon-bearing and/or hydrocarbon-bearing substances, It is known that the ore which for the major part comprises metal oxides (being various ones, even in the case of iron) must be subjected to a reduction procedure before the metal can be obtained. Taking the known process as set forth in the opening part of this specification as its basic starting point, the object of the invention is to make plastic waste, including in organically and/or inorganically contaminated form, useable as a supplier for the constituents of the reducing gas. Plastic waste occurs constantly in large amounts and represents a serious disposal problem. It occurs mostly if not exclusively in solid form, either as packaging waste -which is frequently heavily contaminated -, or as offcuts or the like in the course of the production of plastic articles. Accordingly the invention provides that the carbon-bearing and/or hydrocarbon-bearing substances, at least partially comprising plastic material, which in the process of the general kind set forth in the opening part of this specification are supplied to obtain the reducing gas, are injected in comminuted fluidised form as an agglomerate into the air flow in the hearth of the metallurgical shaft or pit furnace, in particular a blast furnace. That is effected by way of lances which project into the shaft furnace and which are connected to a transport conduit. The plastic material to be injected is fed to the lances by way of that transport conduit. In the event that, contrary to expectation, blockages should occur or hot air should blow back out of the blast furnace into the lance and thus into the transport conduit, a plurality of shut-off or check devices are proposed in the transport conduit, so that the transport conduit is not only protected but immediate resumption of overall operation of the installation and injection of the plastic materials occurs. To dissolve blockages of the plastic material in the transport conduit, there are provided a first and third shut-off device, while a second shut-off device is provided to prevent reverse transportation of plastic material or blow-back of the hot gas masses from the blast furnace into the transport conduit. The mode of operation thereof is set forth in greater detail in the claims but in particular also in the specific description.
