Patent MX-9800700-A (MX)
Title: Method of purifying gold.
Inventor: HANNA MOURAD MICHAEL
IPC: C22B3/06
Filed: 1998-01-23
Abstract: The present invention is a method of increasing the gold content of metallic gold comprising the step of exposing the metallic gold composition to a leach liquor. The leach liquor is selected to dissolve the impurities from the metallic gold composition without dissolving a significant amount of the gold metal. Preferably, the leach liquor is a solution having a highly acidic dissociation constant, a high oxidative potential and a high tendency to complex cations. The present method preferably includes the steps of roasting the gold in an oxidizing atmosphere or atomization before leaching. The metallic gold composition may be repeatedly roasted and leached until the desired gold purity is obtained.

Title: Sulfonated polymers and method of sulfonating polymers.
Inventor: MYERS DAVID L
IPC: C08J7/14
Filed: 1996-08-29
Abstract: Methods of sulfonating a polymer are provided. One method of sulfonating a polymer includes exposing sulfur dioxide and oxygen to free radical producing energy and contacting the polymer with the product of preceding step. Desirably, the steps of exposing sulfur dioxide and oxygen to free radical producing energy and contacting the polymer with this product are performed in a reduced pressure environment. Another method of sulfonating a polymer includes contacting the polymer with sulfur dioxide and oxygen and exposing the contacted polymer to free radical producing energy. The polymer may be contacted with a mixture of sulfur dioxide and oxygen or the polymer may be separately contacted with sulfur dioxide and oxygen. When the polymer is separately contacted with sulfur dioxide and oxygen, the polymer may first be contacted with sulfur dioxide and then contacted with oxygen. The source of the free radical producing energy may be ultra-violet light, electron beam, noble gas radio frequency (rf) plasma, corona discharge, or gamma radiation.

Title: Storage and handling system for cheeses - allowing handling of spherical cheeses and providing adequate ventilation
IPC: A01J25/16
Filed: 1977-01-26
Abstract: The cheese storage system consists of a series of rectangular frames, each having roughly the dimensions of the conventional storage plank. The floor of the frame consists of (plastics) mesh and the vertical cross-section of the floor is the same shape and diameter as the cheeses being stored. The mesh has 4-100 (pref. 9-64) openings per cm.2. The short sides of the frames are fitted with pins which enable the frames to be mounted in a cheese train. The train of frames moves to the right and at the end passees over a roll. A short lever rigidly attached to the short side of the frame then causes the frame to tilt, rolling the cheeses out. The system enables round cheeses to be stored and handled without change of shape occurring and, since the storage surface is of mesh, there is no need to turn the cheeses, which are adequately ventilated.

Title: Anaerobic treatment of natural organic waste - in digester fed by variable speed controlled bucket elevator
IPC: C12M1/107
Filed: 1978-11-06
Abstract: A plant for the anaerobic treatment of natural waste is based on a digester which receives its feed from a supply tank. The transfer is effected by a bucket elevator with a variable speed which charges the digester through a chute. The continuous feed at an adjustable rate eliminates the sudden rush loads on a digester which may result in an excess of volatile fatty acids and may poison the methane producing bacteria.

IPC: C08F4/02
Filed: 1979-04-01
Abstract: (Co)polymerisation of 1-alkenes (with each other or with ethylene) is carried out using a catalyst system comprising (a) an organometallic cpd. from a gp. I-III metal and (b) a Ti halide component comprising a halogenated Ti cpd., (I), an electron donor (II) and a Mg halide-contg. carrier, such that the atomic ratio Ti:Mg is 1:10, esp. 1:1-1:5. During the polymerisation, the H2 concn. in the gas phase in the reactor is held at 0.5 mol. % w.r.t. total moles in the gas phase. The process gives (co)polymers such as polypropylene, having a board molecular wt. distribution and improved processing proterties, e.g. for injection moulding, extrusion and blow moulding. The polymers have a low halogen content and reduced corrosive action on processing equipment.

Patent NL-8204055-A (NL)
Title: Medical X=ray output servo system - controls output of peak intensity beams of image amplifier and operates only if limits are exceeded (HU 28.10.82)
IPC: H05G1/64
Filed: 1982-10-21
Abstract: The system includes a resistance (R) for monitoring the current of the image amplifier (21) for the display of the X-ray installation (19). Alternatively, the output of photo-electric a cell (22) can be used. A pulse, synchronised to the voltage output of the power supply unit (18), triggers a saw-tooth voltage generator (2). When the sawtooth reaches a preset level, a comparator (3) triggers a multivibrator (4) which generates a pulse of fixed duration. This pulse, applied to a switch (1), samples the current waveform at its peak to tive a shaped sample. If the amplified voltage is less than a limit, set by reference voltage generator (11), a comparator (13) causes a servo-motor (17) to drive a variable auto-transformer in the power supply unit (18) so as to increase the X-ray intensity. Conversely, if it is below a limit set by reference generator (12), the motor (17) reduces the intensity. If the X-ray tube itself contains a device for controlling intensity, the limits (12,13) are set so that the servo system operates only outside the range of this device.

Title: Door hinge with bolt between rolled flaps - has sloping socket edges so that swivelling flap rises spirally and returns automatically
IPC: E05F1/06
Filed: 1983-08-12
Abstract: The flat, swivelling door hinge has flaps linked by a bolt, which is housed in rolled sockets on them. On one flap (1), the tops of the rolled sockets (11) have an edge slope (121), and on the other (2) the bottoms have a corresponding edge slope. Between the non-sloping tops and bottoms there is an interval, corresponding to the pitch. Swivel of one hinge flap, relative to the other, about the bolt (10), results in helical vertical movement of the swivelled flap. On completion of swivel, this flap returns to its original rest position, under gravity.
