Granted: 2009-06-23
Abstract: A livestock feeder (50) includes a gravity pulled, fold-down grill (56,57) on both sides of a main frame (51) that can hold a supply of livestock feed such as a hay bale (82) therein. The fold-down grills face each other and fold down on a hay bale positioned on the floor (60) of the feeder as the hay bale is consumed by livestock such as a horse. Grill spacer bars (65, 101) are positioned apart from each other to allow only the muzzle of the feeding animal to reach there through and grasp the hay. The feeder also includes a pair of pivot arms (96-99) at the base of each grill to pivot the grill toward the floor of the feeder. Each pivot arm extends from a rotatable member (69-72) connected to the frame. The rotatable members and grill are lifted to hang the grill on a pair of latches (75-78) that lock the grill in a locked upright position for loading of another bale on the feeder floor through an end gate (58,59) that is rotatably connected to the main frame. The end gate can include spacer bars (105,109) to allow livestock to reach and feed there through.

Abstract: The invention relates to a method and apparatus for thermographically separating lumpy feedstock, and may be used for dressing ferrous and non-ferrous metal ores, mining chemical feedstock, secondary raw material and technogenic waste using an ultrahigh frequency electromagnetic field (UHF). Said radiation frequency is selected in such a way that the electromagnetic wave penetration depth dependent of lump material properties is greater than the lump maximum linear dimension at the peak attenuation of the electromagnetic wave. UHF electromagnetic radiation energy absorbed by the lump material initiates the heating of the components thereof, wherein the component exhibiting a greater electrical conductivity absorbs the greater amount of UHF energy than the component exhibiting a lower electric conductivity during the same time, whereby the heating temperatures of the useful component and the barren stock measured after irradiation are different.

A control nut is rotatably mounted on the frame, the control nut having a screw passage therethrough, the screw passage being positioned to receive the corkscrew and configured to mate with the configuration of the corkscrew whereby, upon longitudinal movement of the corkscrew in the screw passage, rotational movement is imparted to the corkscrew. Actuator means is operatively connected to the carrier for reciprocating the carrier. The apparatus includes first restraint means independent of the control nut for restraining rotation of the corkscrew with respect to the carrier, second restraint means for restraining rotation of the control nut with respect to the frame and latch means for releasably latching the control nut to the frame to restrain relative movement therebetween in the longitudinal direction with respect to the longitudinal axis of the corkscrew.  The first and/or second restrain means comprises a detent on the part whose rotation is to be restrained and a recess for receiving the detent when rotation of the part is to be restrained.

Abstract: L'invention concerne un procédé et un dispositif pour l'amélioration de l'accommodation cornéenne, visant à régler le problème de la presbytie. Des mesures de topologie cornéenne/sclérale en accommodation et hors accommodation indiquent la faculté d'accommodation cornéenne nominale. On peut ainsi déterminer une faculté d'accommodation souhaitée pour améliorer l'état de presbytie, ce qui permet d'envisager une intervention biomécanique sélective dans la structure cornéenne, en dehors de la zone optique, pour l'établissement de régions infléchies, lesquelles tendent à améliorer l'accommodation cornéenne sur présentation d'un stimulus d'accommodation. On peut procéder par exemple à une ablation de surface cornéenne, à une ablation intrastromale, à une kératoplastie conductrice, à une kératoplastie thermique laser et à la pose d'implants en milieu cornéen et/ou scléral. L'invention concerne également un dispositif de mesure de topologie amélioré à champ de vision amélioré qui présente aussi d'autres attributs.
