Title: Joystick control for an automatic depth control system and method
Inventor: BUCHL ANDREW F
IPC: A01B63/111
Filed: 2000-07-04
Abstract: An automatic depth control system is disclosed. The system includes a Console and remote Controller mounted in the tractor cab, power beyond Valving, and Depth Sensors, either ground contact or non-ground contact, mounted on the frame of the implement. The depth sensing system is provided to sense the actual penetration of an implement tool by determining the height of the implement frame above the ground. A circuit system is provided to receive the depth signal and to signal power beyond valving that wilt effect hydraulic corrections in order to maintain the select depth penetration. The Console includes an instrument panel having a toggle switch with AUTO, LOCK and MANUAL positions, an LED showing depth of tool penetration and a bargraph depicting variations from a desired depth and flashing lights on the bargraph to show depth corrections in process. The Console also includes a depth window in which no hydraulic correction would be made, a sensitivity switch, depth sensor switches and an UP/REPHASE switch. A remote Controller provides for a five position, mechanical hold toggle switch to provide separate and distinct settings, a rocker switch to vary depth selections in temporary memory, a RUN/HOLD position on existing tool depth penetration, and a SET switch to place settings from temporary to permanent memory. Power beyond valving, incorporating function with either gear, pressure compensated or load sensing hydraulic pumps, is mounted in line with existing hydraulics to provide hydraulic depth selections in either automatic or manual modes. Depth sensors are either potentiometer (ground contact) or ultrasonic transducer (non-ground contact).

Title: Traitement d'une infection par le virus du papillome au moyen de micobacterium
Inventor: JOCHAM DIETER
IPC: A61K35/74
Filed: 1999-04-29
Abstract: Selon cette invention, une maladie causée par le virus du papillome est traitée par l'application à la zone infectée d'une quantité efficace de Mycobacterium. Plus particulièrement, l'infection par le virus du papillome humain provoque Condylomata acuminata. Malgré de nombreux traitements, les patients souffrant de cette maladie ont fait plusieurs rechutes. On a procédé au traitement au BCG, et ce pendant le traitement principal ou dans le cas des patients qui ne réagissaient pas au traitement standard ou faisaient des rechutes. Après un traitement initial au laser, six hommes souffrant de Condylomata acuminata intra-urétral à récurrence rapide ont suivi un traitement au BCG. On a procédé à une application externe et à une instillation interne du BCG par six fois, avec des intervalles d'une semaine. Les études cliniques comprenaient l'examen et l'inspection endoscopique de l'urètre et de la vessie. Trois patients, qui ont suivi une série complète de traitement au BCG, n'ont pas manifesté de rechutes de Condylomata acuminata. Deux autres patients ont suivi une série de traitement secondaire au BCG ; l'un d'eux a fait une rechute. Enfin, un dernier patient a fait une rechute après un traitement interrompu, suite à un oedème pénien. Le taux de récurrence annuel est passé de 3,2 avant le traitement au BCG à 0,75 après le traitement au BCG (p?0,05, test d'égalité de 2 %). En outre, huit hommes ont suivi un traitement au BCG en tant que traitement principal, sans traitement initial au laser, en suivant le même cours de traitement mais utilisant le BCG dans une crème contenant de l'acide salicylique à effet kératolytique. Sur huit patients, six ont été complètement guéris. Manifestement, la réponse immunitaire induite par le BCG réduit le taux de récurrence chez les patients souffrant de Condylomata acuminata.

Abstract: The utility of soybeans having a composition of greater than 40 % of the protein as beta-conglycinin and less than 10 % of the protein as glycinin for making highly functional high beta-conglycinin compositions was discovered.  The discovered ingredients are useful for mimicking the texturizing properties of casein while also maintaining or improving physiological benefits of soy protein ingredients (e.g., cholesterol and triglyceride lowering properties).  The high stability of the high beta-conglycin compositions against protein-protein aggregation reactions is valuable for creating good tasting beverages and beverage mixes. Cheese with good spreadability, gloss and smoothness was made using an enzyme-modified version of the new ingredient composition.  Cheese with good firmness and meltability was also created using a different enzyme-treatment. High beta-conglycinin compositions were found to demonstrate excellent emulsifying and gelling properties in the pH region (5.5-6.2) relevant to meat applications. High beta-conglycinin compositions also have possible use for improving the composition of essential amino acids for infant humans and animals.
