Abstract: A control system for an in-well pump for recovery of hydrocarbons which are lighter than water. Two electrical probes and a float switch are used to control the automatic raising and lowering of the pump within the well to always maintain its input within the hydrocarbon layer. The pump is also controlled so that it only operates when its input is within the hydrocarbons to assure that it does not pump water and that it is not operated in air.

Abstract: In accordance with the invention, protective coveralls are provided which are easy to put on and take off. The coveralls include a one-piece main suit with arm and leg portions connected to a torso portion having shoulder areas and a neck opening. The main suit includes a slit-like opening extending downwardly from the neck opening adjacent the uppermost area of one shoulder diagonally across the front of the torso portion to the opposite upper leg. A zipper is provided for closing the slit-like opening and an elongate flap is attached to the main suit along and adjacent to the zipper at one side of the opening to cover the zipper. Complementary hook and loop fastening tapes having a width at least 2 cm wide are used for securing the flap to the suit covering the zipper. The coveralls also have an unattached extension of the elongate flap which overlaps further over the opposite side of the opening with the unattached extension being unattached from the main suit along a predominant portion of its length.

Abstract: A novel method for efficiently carrying out pollen-mediated gene transformation of flowering plants is described. Utilizing novel DNA constructs incorporating exogenous DNA fragments coding for specific enzymes, the method can product transformed plants exhibiting novel, useful traits. Confirming hybridization tests have been carried out to identify the exogenous DNA transformed into the plant.

Abstract: A fast packet switching system has an interconnection network associated with a distributed control structure composed of a plurality of processing units (UC1-1 . . . UC3-16) managing the routing at the virtual call level. At least some processing units each associated with a group of network inputs/outputs store bandwidth occupancy data relevant to the interstage links which can be reached from the inputs of the group and are included between the inputs and a central network stage where there is a maximum number of alternative paths or, respectively, bandwidth occupancy data relevant to interstage links which lead to the outputs of the group and are included between the stage and the output, the data being updated whenever a new call is routed.

Abstract: A method for producing anhydrous crystalline fructose by crystallizing from solution is provided. A highly supersaturated aqueous solution of fructose is added to a heel of crystalline fructose and dry seed. The temperature of the solution is then lowered to crystallize fructose from the solution to form a massecuite. The massecuite is divided into a product portion and a heel portion, the product portion being treated to isolated crystalline fructose which is then classified into product cuts on the basis of particle size of the fructose crystals, each product cut having a substantially typical particle size distribution.

Abstract: A process is disclosed for producing high grade synthetic paper containing at least 97 wt. % polyethylene on conventional continuous wet-lay paper-making equipment. In particular, the process comprises preparing a pulp furnish of 97-99.5 wt. % oriented polyethylene fibers and 0.5-3.0 wt. % polyvinyl alcohol fibers and depositing the fibers on the forming screen of a conventional wet-lay paper machine. The resulting waterleaf sheet is then dried on heated PTFE-coated drying cans, using a particular drying profile to reduce sticking and elongation, and then thermally bonded to provide a polyethylene paper having high strength, low defects and excellent uniformity. A process for producing the pulp fibers used in the paper-making process is also disclosed.
