Granted: 1998-08-11
Abstract: A bottle which may be in a straight-up position for storage and in an inverted position for dispensing of condiments, such as ketchup, mayonnaise, mustard, etc.  The top has a cap which may be removed and replaced by a dispensing nozzle.  The bottom has two parallel ridge members and has a hole in the flat area therebetween that is closable with a tethered plug.  When the bottle is ready to be used for dispensing condiments, the cap is replaced with the dispensing nozzle and the bottle is turned upside down.  At this time, the tethered plug is removed so as to release pressure in the bottle so its contents may escape through the dispensing nozzle.  The bottle is of shape and weight so that when inverted and hung on a stand, it will hang properly perpendicular to the ground.  The bottles are also shaped so that they will nestle against one another with very little clearance.  The bottle can be filled with condiments, inverted for dispensing through the dispensing nozzle, and the plug from the vent hole is removed when the bottle is hung upside down and is used.  At the end of the day, the tethered plug is placed in the vent hole, and the bottles are then placed up so they can be stored in refrigeration units.

Title: System and method for uniformly delivering feed rations to the feed-bunks of animal pens in a feedlot
Inventor: BREWSTER SHERMAN H
IPC: A01K5/02
Filed: 1995-04-04
Granted: 2006-12-19
Abstract: A system and method for uniformly delivering assigned feed rations to the feedbunks associated with animal pens. The system includes a feed delivery vehicle having a feed storage compartment and a scale. The function of the scale is to weigh the amount of feed in the storage compartment at sampled time intervals, and produce a first data signal indicative of the weight of the feed at these sampled time intervals. The vehicle also has a ground speed radar unit which measures the two ground speed of the vehicle at sampled time intervals as the vehicle travels alongside of the feedbunk, and produces a second data signal indicative of the vehicular speed at these sampled time intervals. A computer aboard the vehicle processes the first and second data signals along with information regarding the length of the feedbunk and produces a control signal as the vehicle travels alongside the feedbunk. A feed dispensing mechanism aboard the vehicle, includes an electronically-controlled hydraulic pump that dispenses the assigned amount of feed ration into and along the feedbunk in response to the production of the control signal such that, for each foot travelled by the feed delivery vehicle along the length of the feedbunk, a substantially constant amount of feed is dispensed into the feedbunk as the feed delivery vehicle travels alongside the feedbunk.

Granted: 2000-10-24
Abstract: Thaumatin II or thaumatin I can be obtained through the expression, not of their natural genes, but of artificial, synthetic and substantially optimized genes following specific rules.  Preferably, this expression is carried cut in filamentous fungi, especially GRAS fungi and particularly the species Penicillium roquefortii, Aspergillus niger and the awamori variant of Aspergillus niger.  Preparing substantially optimized artificial genes for filamentous fungi, performed here for the first time in the case of thaumatin, allows for high protein expression, making the process useful for industrial production of this valuable sweetener.  Thaumatins may be obtained extracellularly by using a plasmid with a secretion signal, and also intracellularly.  The latter method can be used in animal feed without prior separation from the fungal mycelium.

Abstract: A recording apparatus is to perform complementary recording in order to eliminate the white streak caused by recording elements becoming incapable of recording while recording an image.  Particularly, in an ink jet recording method for recording an image by discharging ink from nozzles, the white streak caused by nozzles becoming incapable of discharging ink can be eliminated by the performance of a complementary recording in accordance with the present invention.    Preceding printing, abnormal nozzles are detected, and then, data related to such abnormal nozzles are removed.  In accordance with such data, one scan printing is performed.  Preceding the returning operation of the printing head subsequent to the one scan, a sub-scanning feed is performed so that normal nozzles are positioned in a location corresponding to the white streak appearing in the one scan printing.          In this way, while returning the printing head, the printing is performed in accordance with such data related to the abnormal nozzles detected at the time of one scan, hence executing a complementary recording appropriately.

Abstract: A position sensor includes a coil of small diameter litz wire wound around a ferrite rod. The rod is secured in the end of a ceramic support and an end cap is secured on the other end of the rod to form a bobbin section on which the coil is wound. Two palladium silver strips are formed axially along the length of the support extending from the bobbin section to near the base of the support.      Two free ends of the coil are formed into strain relief loops and soldered to the strips. Lead wires of comparatively larger diameter are also soldered to the strips but near the base of the support. The strips establish electrical continuity between the coil and the lead wires while separating the end portions of the coil from the lead wires so as to prevent the lead wires from inducing stress into the relatively fragile coil wires.      The lead wires are threaded through a cylindrical metal housing, and the base of the ceramic support is located into a cylindrical recess in the housing to support and seal the working end of the sensor.

Granted: 2000-06-27
Abstract: A gear mechanism for reducing a rotational speed of a driving gear and transferring the reduced rotational speed to a gear to be driven comprises an arbitrary number of gear teeth attached to the driving gear and smaller than the number of teeth determined by a module and a stopper having a stopper surface which is attached to the driving gear so as to be displaced relative to said gear teeth along the axial direction of the driving gear and which draws a circle identical in size to a circle drawn by a locus of rotation of an addendum of each gear tooth upon rotation of the driving gear and meshes with gear teeth of the driven gear upon disengagement of the gear teeth from the teeth of the driven gear so that the rotation of the driven gear is controlled by the stopper.  Thus, when the gear teeth are in disengagement with the teeth of the driven gear, the stopper is maintained in meshing engagement with the gear teeth of the driven gear so as to prevent the driven gear from rotating.

Abstract: L'invention se rapporte au réceptor humain H4-1BB, qui a été isolé et séquencé. L'ADNc du récepteur humain H4-1BB présente une homologie d'environ 65 % avec l'ADNc de 4-1BB de souris, et a été isolé au moyen de sondes dérivées de l'ADNc de 4-1BB. Une protéine fusionnée permettant de détecter des ligands de membrane cellulaire se liant au récepteur protéique humain H4-1BB a été développée. Elle comprend la partie extracellulaire du récepteur protéique H4-1BB ainsi qu'une protéine de détection (phosphatase alcaline) liée à la partie du récepteur protéique H4-1BB. Des lymphocytes B ayant exprimé un ligand se liant au récepteur protéique H4-1BB peuvent être traités au moyen de cellules qui ont exprimé ledit récepteur protéique, la prolifération des lymphocytes B pouvant ainsi être induite. L'utilisation de l'H4-1BB pour inhiber la liaison ligand/H4-1BB s'applique en pratique à la dépression du système immunitaire au cours d'une transplantation d'un organe. Un anticorps monoclonal dirigé contre H4-1BB peut être utilisé pour accroître la prolifération des lymphocytes-T selon un procédé consistant à traiter des lymphocytes T qui ont exprimé le récepteur protéique H4-1BB avec l'anticorps monoclonal anti H4-1BBL. Des tumeurs transfectées avec le récepteur H4-1BB sont susceptibles de produire des signaux spécifiques d'antigènes ainsi que des signaux co-stimulants, et peuvent être détruites par des lymphocytes-T humains cytotoxiques.
