Abstract: The present invention provides grain, seed, feed made from the g rain or seed, petfood made from the grain, and food products made from the grain. The grain may be maize grain with the following characteristics: oil burdened, elevated protein content, and low phytate levels. The combination of oil burdened, protein laden, decreased phytate characteristics in grain makes a grain that provides more calories, protein and phosphorus and other nutrients to the feeding animal. Pet foods, and animal feeds and corn food products made of the present invention will provide increased nutrition because of the increased bioavailability of the components of the grain.

Abstract: The alignment, and positioning of an external device (116) relative to an internal device (128) are indicated on a display (110), and/or by an acoustical signal. In the disclosed application, the external device (116) trans-cutaneously transmits electromagnetic energy to an internal receiver (128) to provide electrical power for an implanted medical device (128). To ensure optimal coupling between the external transmitter (116) and the internal receiver (128), two permanent magnets (125, 126) are disposed at spaced apart positions on the internal receiver (128). The magnetic field strength of the permanent magnets (125, 126) is sensed by a pair of correspondingly spaced apart Hall effect sensors (120, 121) on the external transmitter (116). As the external transmitter (116) is moved about over the internal receiver (128), the signals produced by the Hall effect sensors (120, 121) drive a display (110) of light emitting diodes (LEDs) (112) that indicates when the maximum magnetic field strength is achieved, i.e., when the Hall effect sensors (120, 121) on the external transmitter (116) are each positioned directly opposite the corresponding permanent magnets (125, 126) on the internal receiver (128).

Title: A method of purifying acid leaching solution
Inventor: SUNDKVIST JAN-ERIC
IPC: C22B15/00
Filed: 2000-04-18
Abstract: A method of purifying an acid leaching solution obtained by processing hydrometallurgically material that contains valuable metals and also Fe3+ and Fe2+, and possibly also arsenic in solution. The major part of the Fe3+-content and the arsenic is precipitated out in a first stage, by adding pH-elevating agent to the leaching solution. The precipitate formed in the first precipitation stage is extracted from the solution and removed from the process. The solution is oxidised in a second precipitation stage while adding a further pH-elevating agent for oxidation of Fe2+ and precipitation of resultant Fe3+ and any arsenic still present. The resultant precipitate and any residual solid pH-elevating agent are then extracted from the solution and returned in the process to more acid conditions, and the thus purified solution is then processed to win its valuable metal content in a manner per se. The pH is suitably raised during the first stage to a value in the range of 2.2-2.8, and in the second stage to a value in the range of 3.0-4.5. The oxidising process in the second stage is suitably effected by injecting air into the solution and by preferably using lime or limestone as the pH-elevating agent. Solid material extracted from the second stage is returned beneficially to the first stage. Some of the solid material taken from each precipitation stage can be recycled within respective stages as a nucleating agent.

Title: Reinforced reclosable package seals
Inventor: FORMAN HAROLD M
IPC: B65D33/25
Filed: 2000-07-24
Abstract: Packages having improved openable and resealable interlocking closures and methods and apparatus for making the same from a continuous web of film, the closure having male and female portions and being formed either in line with or transversely to the direction of film flow during package formation at line speed. A converter device adjunct to standard packaging apparatus forms a small amount of the running packaging film into a multilayer strip as an integral part of the film. The converter functions with both horizontal and vertical form/fill/seal wrapping machines and with overwrap packagers, and uses diverse packaging films and film laminations of which the substrates may be non-plastic. The packaging film is fed into the converter where the film is fanfolded to form a stack, the layers of which are heat sealed together forming a multilayered strip in plane with the film. The number of stack folds varies depending on the thermoforming properties and thickness of the particular film being used. The strip is abraded on one surface to selectively remove the thermoplastic coating, the film then passing into the package former where product wrapping takes place in packages having single or double overlap longitudinal package seals, and which places portions of the strip in stacked apposed position. The package ends are sealed and the package resealable locking closure is formed in the strip. The female portion of the locking closure is formed in the package face that includes the overlapped longitudinal package seal which includes multiples of the strip and optional additional layers. In another embodiment the strip is not abraded and the inner and outer parts of the resealable closure are separately formed before package formation takes place. Alternatively to form the strip, layering other than by fanfolding to form a stack may be utilized, as for example heat sealing a strip of heat sealable material to the packaging film. Also optionally formed in the resealable closure are hinges and reinforcing V-notches.

Title: Clamp assembly for pick-up truck topper
Inventor: MORIN YVON
IPC: B60J7/185
Filed: 2000-10-31
Abstract: A clamp assembly for releasably securing a cab or other truck toppers to a pick-up truck box includes a master and slave assemblies mounted to a transverse section of the sidewall of cab and spaced-apart from each other. Each assembly has an engagement member pivotable between an operative position in which the engagement member extends beneath an inwardly extending flange of the sidewall of the truck box and abuts the undersurface of the flange, and an inoperative position in which the engagement member clears the flange. A set of worm and worm gear is provided in the master assembly and a worm gear shaft extends through the master and slave assemblies to drive the rocker members in the pivotal movement. The clamp assembly is operated using a rotating tool from inside of the cab so that unauthorized removal of the cab from the truck is prevented. The use of the clamp assembly not only advantageously reduces the labour required to secure the cab to the truck box but also permits, in a limited extent, a discrepancy between the truck box and the cab in instant deformation.
