Title: Process for high extraction of zinc from zinc ferrites
Inventor: ROSATO LUCY
IPC: C22B3/08
Filed: 1993-08-24
Abstract: Abstract of the Disclosure:          A process  for high extraction of  zinc  from calcine containing zinc oxide and zinc ferrite, comprises the steps of leaching such calcine with a sulphuric acid bearing solution in a neutral leach stage followed by a low acid leach stage with a first solid-liquid separation stage between the neutral and low acid leach stages to dissolve the zinc oxide while leaving the zinc ferrite substantially undissolved, separating a residue containing the zinc ferrite in a second solid-liquid separation stage following the low acid leach stage,  leaching the zinc ferrite with a sulphuric acid bearing solution at an initial acid concentration of 50-60 g/l and a temperature of 90°C up to boiling to simultaneously dissolve the zinc ferrite and precipitate the iron content of the ferrite as a jarosite by the addition of ammonia or other alkali ions to the leaching solution, separating a residue containing jarosite  in  a  third  solid-liquid  separation  stage, neutralizing  the  overflow  of  the  third  solid-liquid separation stage to a pH of about 1.4-1.8 with neutral leach underflow from the first solid-liquid separation stage or calcine at a temperature of at least 75°C to further precipitate  iron as  jarosite  and reduce  the soluble  iron  concentration  to  less  than  4  g/l,  and recycling  the  content  of   the  neutralization/iron precipitation stage to the low acid leach stage.
Patent CA-2107508-A1 (CA)
Inventor: DANIEL WADE K
IPC: B65D51/16
Filed: 1993-10-01
Abstract: The present invention provides a package such as a cylindrical can for containing a particulate product, such as roast and ground coffee,  under  pressure.   The  package  automatically  releases  the pressure upon opening while preventing the escape of the particulate product.  The package is made from a container having a closed top, a closed bottom, and an enclosed body between the top and the bottom. The package includes a venting member disposed within the container near the top.  One end of the venting member abuts against the body of the container along its perimeter and another end abuts against the top of the container along its perimeter.  The package further includes a channel  between the venting member and the container. When the container is initially opened with a can opener, the top of the  container  is  punctured  in  an  area  above  the  channel.  The pressure is then released from the container into the channel and out of the  package  while  the  particulate  product  is  prevented  from escaping.

Title: Method and apparatus for communication between equipment units
Inventor: TANAKA SHIGEO
IPC: H04N5/00
Filed: 1993-10-05
Abstract: ABSTRACT OF THE DISCLOSURE A communication method and apparatus simplifying received data processing and eliminating use of high-speed processing equipment.  In the first communication apparatus according to this invention, received data of different types are stored in respective buffers, so that the received data need not be read out immediately but may be read only when required, thereby eliminating use of high-speed processing apparatus.  Additionally, received data need not be sorted after being read from the buffers, thereby simplifying the processing of the system.  In the first communication method according to this invention, if a command and a request are the same in operand, the operand of the request is not sent, thereby reducing an amount of data to be transmitted.  In the second communication method according to this invention, communication is always performed in the unlocked state, so that no unlocking instruction is required to change states from locked to unlocked, thereby further reducing an amount of data to be transmitted.

Title: Brain cooling device and method for performing the same
Inventor: KLATZ RONALD M
IPC: A61F7/02
Filed: 1992-05-19
Abstract: This invention discloses a device and a method for resuscitating the brain as result of ischemic and anoxic injuries whereby the patient survives neurologically intact. The device includes a head enveloping helmet (30) and neck supporting back plate (50) with interconnected hollow cavities to allow chilled fluid from an activated coolant source (62) to pass therethrough and subsequently chill the brain and upper spinal column. Once chilled, the brain's metabolism is slowed whereby resuscitation efforts can continue while neurologic damage is minimized. The method includes placing and adjusting the helmet (30) on the patient's head, placing the back plate (50) under the patient's neck and into abutment with the helmet (30), connecting the helmet to the coolant source (62) and activating the coolant source (62).

Title: Plural-mode stacked resonator filter
Inventor: FIEDZIUSZKO SLAWOMIR J
IPC: H01P11/00
Filed: 1993-10-28
Abstract: A filter for an electromagnetic signal is formed of a set of planar resonators, preferably of superconductor material, interspersed among a set of electrically conductive sheets, outermost ones of the sheets serving as ground planes, and the inner ones of the sheets having irises for coupling electromagnetic power between the resonators. The resonators and the sheets have a planar shape, are parallel to each other, and are stacked one upon the other. Dielectric material insulates and serves to support the resonators and the sheets in their respective locations. There are at least two resonators in the set of resonators, and at least one inner sheet of the set of sheets. A first coupling element serves to couple an electromagnetic signal to a resonator of the filter, and a second coupling element serves to extract an electromagnetic signal, preferably from another of the resonators. The first coupling element excites in a first of the resonators a first mode of electromagnetic vibration in a plane defined by the axis and a point of coupling of the first coupling element. Each of the resonators, in a preferred embodiment of the invention, is provided with a perturbation, such as a notch or a tab in a peripheral portion of the resonator, distant from the plane and from a coupling point for inducing a second mode of electromagnetic vibration perpendicular to the first mode, thereby to provide the function of a multiple pole filter with half the number of resonators,

Inventor: ARAGONES JUAN LUIS BOUSO
IPC: C22B15/00
Filed: 1994-01-07
Abstract: Process for biolixiviating minerals from copper sulfides and also from their flotation concentrates, characterized by the use of biolixiviation through indirect contact as well as separation and improvement of the chemical and biological steps of the biolixiviation process.  In the chemical step, a low concentration of ferric sulfate is used as the lixiviating agent.  In the biological step, bacterial films of Thiobacillus ferrooxidans attached to an inert solid are used to regenerate the lixiviating agent by converting the ferrous ion into ferric ion through oxidation.  The regenerated agent is then recycled to the lixiviation reactor.  The biolixiviation process permits complete extraction of the copper contained in the ore and results in a lixiviation liquor which contains all the copper charge and a low concentration of ferric sulfate similar to the low concentration of ferric sulfate used initially.  The copper obtained can be treated without difficulty by means of extraction with solvents and electrolysis in order to obtain cathode copper.

Abstract: Methods are disclosed for the production of anti-self antibodies and antibody fragments, being antibodies or fragments of a particular species of mammal which bind self-antigens of that species. Methods comprise providing a library of replicable genetic display packages (rgdps), such as filamentous phage, each rgdp displaying at its surface a member of a specific binding pair which is an antibody or antibody fragment, and each rgdp containing nucleic acid sequence derived from a species of mammal. The nucleic acid sequence in each rgdp encodes a polypeptide chain which is a component part of the sbp member displayed at the surface of that rgdp. Anti-self antibody fragments are selected by binding with a self antigen from the said species of mammal. The displayed antibody fragments may be scFv, Fd, Fab or any other fragment which has the capability of binding antigen. Nucleic acid libraries used may be derived from a rearranged V-gene sequences of unimmunised mammal. Synthetic or artificial libraries are described and shown to be useful.
