Title: Apparatus and method for hydrolysis of cyanide-containing liquids
Inventor: BELL DAVID H
IPC: C02F9/00
Filed: 1991-10-10
Abstract: The invention provides an apparatus for continuous thermal hydrolysis of cyanide ions and cyanide-containing ions contained in a liquid, comprising an elongated tubular reactor of a size selected to enable the liquid to be retained in the reactor for a predetermined reaction time, a conduit for supplying the liquid to the reactor, means for adding a base to the liquid prior to heating, and means, associated with the conduit, for instantaneously and uniformly heating the liquid to a preselected temperature. The apparatus preferably uses high pressure steam to heat the liquid and appears much less subject to fouling by scale. The invention also provides a continuous process for hydrolyzing a cyanide-containing liquid stream, comprising adjusting the pH of the liquid stream to render the liquid stream strongly basic; rapidly and uniformly heating the liquid stream to a predetermined elevated temperature; feeding the liquid to an elongated substantially vertical tubular reactor; maintaining the liquid in the reactor for a predetermined time to permit substantially complete degradation of cyanide ions and cyanide-containing ions in the liquid. The cyanide-containing liquid may preferably be uniformly and rapidly heated to the desired temperature by injecting steam under pressure into the liquid.

Title: Can crushing utensil
Inventor: FINLEY NEIL M
IPC: B30B9/32
Filed: 1992-08-06
Abstract: A manual beverage can crushing utensil having a base (8), a pivot member (2), a lever (1) pivotally attached to the top of the pivot member, and an upper crushing anvil (3) pivotally attached to the lever outwardly from the pivot member. A link (4) pivotally attached to the pivot member above the lever is also pivotally attached to the top of the upper crushing anvil, thereby maintaining, throughout the crushing stroke, the upper crushing anvil in generally vertical axial alignment with the beverage can, whose rims mate with the undersurface of the upper crushing anvil and with a can-receiving anvil on the base. The undersurface of the upper crushing anvil is at a slight angle to the horizontal at the beginning of the crushing stroke so that initial collapse of the can begins under moderate crushing force and is substantially parallel to the base at the end of the stroke. In one embodiment of the invention the crushing utensil may include a suction mechanism (10) coupled to the base for grippingly adhering the base to a flat support surface. The suction mechanism preferably consists of a suction cup attached to a lever arm pivotably and lockably coupled to a rear portion of the base.

Patent CA-2099435-A1 (CA)
Inventor: HAMEL GERALD
IPC: B23D59/00
Filed: 1993-06-30
Abstract: A board edging infeed optimization system is described for feeding a board into an edging device capable of longitudinally cutting the wane edges of the board.  The infeed system is equipped with a  conveyor which transversely advances the board along a straight path, a conventional optical scanning station,  and a computer which calculates a longitudinal reference datum line and a preferred edging path for the board and places movable positioning pegs at a predetermined distance away from the preferred edging path.  A  novel  mechanism is used to seize and transport the board further along the path by the predetermined  distance  so  that the board's  longitudinal  reference datum line  is placed colinear with the preferred infeed line into the edging device.  The novel mechanism is characterized by the use of rotatable eccentric arm which sequentially advance and retract movable clamping jaws.  After the board is placed along  its  preferred  infeed  line,  grip  rollers  can longitudinally feed  it into the edging device.   If required, friction shoes may be installed directly above the general location of the positioning pegs to ensure that the advancing boards will sequentially come to rest in abutment with the positioning pegs and will not bounce or slide out of position.  The eccentric arm assembly can optionally be provided with fluid operated telescopic arms which can be quickly adjusted to allow the infeed optimization system to selectively feed boards to a plurality of adjacent edging devices.

Filed: 1993-10-19
Abstract: Case for storing and cleaning contact lenses ABSTRACT      A case for storing and cleaning contact lenses comprising a container being filled with suitable cleaning  liquid  and movable  mechanism screwed on top of the container. The contact lenses  are  mounted  at  suitable  locations  of  the  movable mechanism  so  that  they  may be immersed within the cleaning liquid and each lies in between a pair  of  reversely  rotating blade  bearing  means.  These  blade  bearing  means are set in alternate clockwise and anticlockwise rotation when a top  head cover  of  the case is pressed downwards and then returns under the action of a compression spring. This operation  results  in the  above  blades  mildly  sweeping off any proteinic or other remnants from both the inner concave and outer convex  surfaces of the contact lenses.

Title: Particle sizing
Inventor: CANTRILL JAMES E
IPC: C08F2/02
Filed: 1994-06-30
Abstract: PARTICLE SIZING                 ABSTRACT OF THE DISCLOSURE The volume average diameter of relatively large rubber-like composite particles dispersed through out a continuous resin phase may be reduced by subjecting the syrup to a shear field.  The application of a uniform shear field generator to the relatively large rubber-like composite particle syrup is particularly desirable since it gives a high degree of control over the size and distribution of the dispersed rubber-like composite phase.  As a result it is possible to optimize the particle size distribution in an impact modified thermoplastic and obtain better or a better balance of properties.

Abstract: A lens (10) imposed of a single material and having at least one refractive surface (14) on one face and a kinoform (20) on the other face(16). The pure refraction between the surfaces varies dimensionally and in refractive index in response to temperature changes and thereby-changes characteristics, such as the back focal length, of the lens while the kinoform varies differently in response to the same temperature changes. The kinoform power is sufficient to vary the temperature induced characteristic changes of the lens in an opposing sense at a given wavelength and in an amount sufficient to athermalize the optical device. In one embodiment the kinoform power compensates for the combined temperature-induced effects upon the refractive portion and any mount that supports the lens:

Abstract: Sufficiently high blood benzopyrone levels cannot be achieved on oral administration of benzo-pyrone.  From the point of view of pharmacokinetics and chronic application, the use of benzopyrone as an oint-ment is not optimal because the blood levels thus achievable cannot be controlled.        It has now surprisingly been found that benzo-pyrone in a particular formulation as part of a trans-dermal therapeutic system (TDS), after application to the skin, is released to the skin in a constant manner as a function of time and over a longer period owing to the absorption of perspiration, and that constant therapeutically effective blood and tissue levels of benzopyrone are achieved in humans, which levels are a factor of 50 higher than those following the oral ad-ministration of the same doses of benzopyrone.
