US Classification:

563271, 171 38, 99544, 99547

Abstract:

A mechanical harvester for harvesting produce with a core planted in a field is provided. The mechanical harvester includes a chassis, a positioning apparatus, a decoring device, and a transport assembly. The positioning apparatus is connected to the chassis and configured to position the produce in the ground for harvesting and decoring.

International Classification:

A23N 15/04

US Classification:

426231

Abstract:

A system for trimming a lettuce head using a digital imaging system and cutting mechanism. The lettuce head is conveyed between a lower feed conveyor and an upper feed conveyor that is disposed a fixed distance over and substantially aligned with a lower feed conveyor. The digital imaging system is configured to capture an image of the lettuce head and determine a cutting profile using the image. The cutting mechanism is disposed over the lower feed conveyor and includes: a servo motor mechanically coupled to a drive shaft; an armature with a pivot end mounted to the drive shaft and a sweep end disposed a radial distance from the pivot end; a cutting nozzle, mounted to the sweep end of the armature, configured to trim the lettuce head; and servo-control circuitry configured to articulate the cutting nozzle through a cutting arc based on the cutting profile.

US Classification:

435181

Abstract:

Polypeptides such as enzymes and insulin are coupled to polyethylene glycol or polypropropylene glycol having a molecular weight of 500 to 20,000 daltons to provide a physiologically active non-immunogenic water soluble polypeptide composition. The polyethylene glycol or polypropylene glycol protect the polypeptide from loss of activity and the composition can be injected into the mammalian circulatory system with substantially no immunogenic response.

Appl. No.:

5/827349

Inventors:

Frank R. Davis - Montclair NJ

International Classification:

G01N 3106

US Classification:

23232R

Abstract:

Personal dosimeter, which provides great ease in immediately obtaining reading results, includes a plastic tube, open on the bottom, and containing near its top, a well through the bottom of which is inserted a piece of inert wick and a cover made of a soft plastic placed over the top of the tube. When the dosimeter is to be put into use, a predetermined amount of liquid reagent is injected into the well formed near the top, which reactant moves by capillary action into the inert wick where it adsorbs, absorbs or reacts with a toxic substance to be measured by the dosimeter. After the required time period for measuring exposure, the dosimeter is turned over, additional reactant placed in the tube from the bottom and mixed with the reactant therein, the reactant then being used to determine the concentration of the toxic substance.

International Classification:

C07K 1300
C07K 1708

US Classification:

530385

Abstract:

The present invention relates to chemically modified hemoglobin produced by a novel and efficient method in which stroma-free hemoglobin is first effectively deoxygenated and reduced and then conjugated with a polyalkylene oxide such as polyethylene glycol (PEG) under conditions which maintain the structural integrity of the heme oxygen binding site. In specific, preferred embodiments of the invention, the deoxygenation and reduction is performed under an inert atmosphere by the amino acid cysteine. In additional specific, preferred embodiments, the structural integrity of the heme oxygen binding site is maintained by a high anionic concentration in the reaction mixture. In further preferred specific emodiments of the invention, the polyalkylene oxide is polyethylene glycol; in still further preferred specific embodiments of the invention, the polyalkylene oxide is linked to hemoglobin via a urethane (carbamate) linkage. The novel PEG-modified hemoglobin compounds of the invention exhibit superior oxygen transport capabilities, extended half-life, and importantly, low immunogenicity.

International Classification:

A01D 45/00
A01D 61/02

Abstract:

A mechanical harvester for harvesting a produce with a stem/core planted in a field is provided. The mechanical harvester includes a chassis, and a cutting device and a transport assembly connected to the chassis. The cutting device is configured to cut the stem/core of the produce. The transport assembly is configured to transport the produce cut by the cutting device. The transport assembly includes a movable first belt and a movable second belt. The movable first belt includes a first set of produce grippers and the movable second belt includes a second set of produce grippers. When the produce cut by the cutting device is held between the first set and second set of produce grippers, a portion of the first set of produce grippers opposes a portion of the second set of produce grippers. The opposing produce grippers are configured to compress and exert a force on the produce to hold the produce between the movable first and second belts.
