Title: Crop sensing apparatus
Inventor: GALE GERALD ELLIS
IPC: A01D41/06
Filed: 1991-10-11
Granted: 2001-05-29
Abstract: In a crop stripping apparatus for harvesting grain from standing crop, the height of an overhead hood (18) is adjusted in response to the position of the top of the crop. A sensor housing or nose (34) protrudes forwardly from the hood (18) and has a sloping undersurface (35) which contacts the crop. A pair of cooperating sensors (37) and (38) sense the position of the top of the crop by contact of one or both or neither of the sensors with the top of the crop. The crop slides along the undersurface (35) of the nose (34) with minimum disturbance to the grain heads by the effect of the sensing operation. The nose (34) is mounted in such a manner that the undersurface (35) is maintained at a constant inclination to the ground during vertical movement of the nose (34).

Title: Process for producing metals and metal alloys in a smelt reduction vessel
Inventor: KEOGH JOHN VINCENT
IPC: C21B13/14
Filed: 1991-03-13
Granted: 2003-10-21
Abstract: A process and a smelt reduction vessel (1) for producing metals and metal alloys, in particular iron and iron alloys, from metal oxides and ores in a smelt reduction vessel. The process and the vessel are characterised in that loss of liquid and solids with waste gases (11) from the vessel are minimised by causing the waste gases, oxidising gases (5) and entrained liquid and sol-ids in the space in the vessel that is above the molten metal to rotate about a vertical axis of the vessel thereby forcing liquid and solids outwardly toward the wall of the vessel. This rotational motion may be caused by injecting some or all of the oxidising gases through tuyeres (4) positioned above the bath surface obliquely to a vertical plane through a vertical axis of the vessel. The vessel may have a substantially rotationally symmetrical shape at least in the space above the molten metal (2A).

Title: Hot stamping glass
Inventor: KAMEN MELVIN E
IPC: C09D11/10
Filed: 1993-05-25
Granted: 1998-08-11
Abstract: The present invention provides methods of decorating a glass substrate with hot stamping foil.  The method includes applying a radiation curable adhesive ink to a glass substrate in a predetermined design that leaves some of the glass ink-free. The ink is designed when cured to bond to glass and when heated after curing to adhere to hot stamping foil.  The ink is cured on the substrate by exposing it to radiation, thereby bonding the ink to the glass.   The foil sheet is pressed against the substrate with a compress at a temperature sufficient to cause the foil to adhere to the heated, cured ink design but not to the ink-free areas of the glass.  The foil is peeled away leaving behind a portion adhered to the adhesive ink design.   The substrate does not need further irradiating to complete adherence of the hot stamping foil.

Title: Controlled material flow hydroforming
Inventor: ROPER RALPH E
IPC: B21D26/02
Filed: 1993-07-09
Granted: 1998-04-14
Abstract: A self-contained apparatus for forming metal sheet is adapted for operation within a standard double action press having a base and outer and inner vertically reciprocating slides and includes a basic die mountable to the press and specific tooling replaceably mountable to the basic die. The basic die includes a riser mountable to the outer slide, a manifold mounted atop the base of a tub, and hydraulic cylinder assemblies mounted atop the base and in connection with the manifold and mechanically actuatable by the inner slide for providing pressurized fluid to the specific tooling. The specific tooling includes mating upper and lower dies connected to the riser and manifold, respectively, and movable between open and closed positions. A sheet metal blank positioned upon the lower die is wrapped around the upper die as the upper die is moved down to a closed position by the outer slide, the blank being clamped between the upper and lower dies whereby the periphery of the blank is gripped between a male and female bead mounted all around a part print cavity in the upper and lower dies, respectively. The outer slide then dwells while the inner slide moves down, engaging and actuating the cylinder assemblies, causing hydraulic fluid to be forced into a region between the clamped blank and the lower die, the blank being formed into the part print cavity defined in the upper die. The male bead exerts varying control on the sheet to allow it to stretch across portions of the cavity while flowing into other portions of the cavity. A locking mechanism prevents the bending of the dies and holds the dies in a closed position thereby assisting the engagement of the male bead with the female bead. As a safety feature, the mechanism is configured to automatically open when the die cavity is moved up. The locking mechanism allows the use of high pressures to make large parts, such as car hoods, doors, deck lids, and quarter panels in conventional currently available double action presses.

Granted: 1999-08-24
Abstract: Cette invention offre un processus amélioré de récupération de l'acide citrique d'un liquide contaminé, comme un bouillon de fermentation, par l'addition d'un acide fort ou des sels de ces acides à une solution concentrée d'acide citrique. Le processus prévoit essentiellement une purification en une étape sans les problèmes d'élimination des déchets ou l'important investissement en capital liés aux processus de récupération par extraction au solvant ou à la chaux sulfurique. La récupération peut être davantage améliorée en traitant la solution de réserve restante après la séparation des cristaux d'acide citrique pour obtenir un rendement supplémentaire. L'acide fort privilégié est l'acide sulfurique et le traitement de solution de réserve privilégié est une colonne de résine à exclusion ionique. Même si le processus amélioré est particulièrement avantageux lorsqu'il est utilisé comme un processus de purification en une étape pour l'acide nitrique directement à partir de bouillon de fermentation, il peut également être utilisé conjointement avec les divers liquides contaminés à traiter générés par le processus de récupération par extraction au solvant ou à la chaux sulfurique.
