Abstract: A process for treating spent potliner material from aluminum reduction cells and recovering useful products. In the process, spent potliner material is introduced into an acid digester containing, for example, sulfuric acid.     A gas component is produced which includes hydrogen fluoride and hydrogen cyanide. A slurry component is produced which includes carbon, silica, alumina, sodium compounds such as sodium sulfate, aluminum compounds such as aluminum sulfate, iron compounds such as iron sulfate, magnesium and calcium compounds such as magnesium and calcium sulfate. The slurry component remains in the digester after the gas component is removed. The gas component is recovered and heated an effective amount to convert or decompose the hydrogen cyanide to a remaining gas component including CO2, H2O, and nitrogen oxides, as well as HF gas. The remaining gas component is directed through a water scrubber in which the HF gas is converted to liquid hydrofluoric acid. The hydrofluoric acid is then admixed with alumina trihydrate to form aluminum fluoride and water. Valuable refractory materials and salts are recovered also.

Abstract: The present invention prevents coolant from leaking out of a valve means (23) alter a supply pump (4) stops supplying the coolant, and diminishes a time-lag between the onset of supplying the coolant and mist generation, when the supply pump (4) starts supplying the coolant again. In the machine tool of this invention, the coolant is supplied from a coolant supply pump (4) into a mist generator (13) provided on the tip of a spindle (8) by way of a coolant supply line (7), and a valve means (23) is provided at an inflow part for coolant of the mist generator (13) to be closed when the coolant pressure within the coolant supply line (7) lowers below a fixed level. A means (2) sucks a fixed amount of coolant in the coolant supply line (7), when the coolant supply pump (4) stops supplying the coolant. On the other hand, the means (2) supplies a fixed amount of coolant into the coolant supply line (7), when the coolant supply pump (4) begins supplying the coolant.

Patent CA-2369812-C (CA)
Inventor: ABBOTT GEOFFREY W
IPC: C12Q1/6883
Filed: 2000-04-14
Granted: 2012-09-18
Abstract: The present invention is directed to genes and gene products related to Min-K which form ion channels and to a process for diagnosis of ion channel disorders, including long QT syndrome (LQT). For example, KCNE2 forms IKr potassium channels and is associated with LQT. LQT is diagnosed in accordance with the present invention by analyzing the DNA sequence of KCNE2 of an individual to be tested and comparing the respective DNA sequence to the known DNA sequence of a normal KCNE2 gene. Alternatively, these MinK-related genes of an individual to be tested can be screened for mutations which cause ion channel disorders, including LQT. Prediction of ion channel disorders, including LQT, will enable practitioners to prevent the disorders using existing medical therapy. This invention is further directed to the discovery that the HERG and KCNE2 (also known as MiRP1) proteins coassemble to form a cardiac IKr potassium channel.

Granted: 2014-08-05
Abstract: Live virus vaccines comprise attenuated viruses, while other vaccines comprise killed viruses or parts thereof. It has now been found that the immune response induced by oral poliovirus vaccine (OPV), which is a live vaccine, is cross-reactive with non-polio enteroviruses. OPV is therefore useful in the prevention of non-polio enterovirus diseases, especially Type 1 diabetes mellitus (IDDM). OPV is also useful in combination with killed/subunit non-polio enterovirus vaccines, whereby it prevents harmful side-effects of the killed/subunit vaccine by shifting the immune response from a harmful Th2-type response to a Th1 type response.

Title: Electrical device for evaporating a volatile liquid
Inventor: RYMER SHAUN
IPC: A01M1/20
Filed: 2000-09-25
Granted: 2008-02-19
Abstract: An electrical device for evaporating a volatile liquid (for example an air freshener) into a room employs a wick (14) which extends upwardly from a container of the volatile liquid. A ring heat (16) is in the vicinity of the end of the wick, and assists the evaporation. Vapour escapes from the device through an aperture (10) above the wick, in a casing. The vapour emission rate is controlled by a user, who operates a control member in the casing, to alter the vertical position of a tubular body (18). Vapour may flow from the wick to the exterior through the tubular body (18), and then through the aperture (10). However in all positions of the tubular body vapour may also flow to the aperture, and thence to the exterior, by an auxiliary route, not through the tubular body. It is found that the provision of this auxiliary route for vapour significantly improves the performance of the device. The tubular body (18) comprises an upper surface (31) comprising a wall (32) and apertures (33). The wall (32) together with the apertures (33) ensures that any unevaporated volatile liquid is directed back towards the heater.

Abstract: In the formation of microstructures, a preformed sheet of photoresist, such as polymethylmethacrylate (PMMA), which is strain free, may be milled down before or after adherence to a substrate to a desired thickness. The photoresist is patterned by exposure through a mask to radiation, such as X-rays, and developed using a developer to remove the photoresist material which has been rendered susceptible to the developer. Micrometal structures may be formed by electroplating metal into the areas from which the photoresist has been removed. The photoresist itself may form useful microstructures, and can be removed from the substrate by utilizing a release layer between the substrate and the preformed sheet which can be removed by a remover which does not affect the photoresist. Multiple layers of patterned photoresist can be built up to allow complex three dimensional microstructures to be formed.
