Abstract: There is disclosed a novel process of preparing highly pure monoamido acid by the reaction of a dibasic acid and an amine wherein a large molar excess of dibasic acid is utilized and conveniently recovered for recycle in the process to prepare additional amounts of the said monoamido acid. It has been discovered that amidation of both acid groups of the dibasic acid is held to low levels while efficiency of the reaction is maintained by recycle of unreacted starting acid. The unwanted diamido compound is separated from the desired product by first forming a water soluble salt of the monoamido acid then removing it from the insoluble diamido by-product by conventional means such as filtration. The desired monoamido acid may be recovered by acidification of the salt thereby precipitating the acid for easy recovery from an aqueous medium.

Abstract: The present invention concerns a novel process for using a recently discovered dipeptidylaminopeptidase isolated from the cellular slime mold, Dictyostelium discoideum (dDAP). The claimed process involves immobilizing dDAP onto a support surface so that even numbered, N-terminal dipeptides can be efficiently removed from precursor proteins or polypeptides to yield desired processed proteins or polypeptides. The invention provides a means for reusing dDAP in multiple conversion reaction runs, as the enzyme does not become a part of the substrate/product solution. The claimed process is particularly useful for converting a precursor human proinsulin analog (Met-Arg-Human Proinsulin having Lys at position 28 and Pro at position 29 of the corresponding insulin B-chain; MR-KPB-hPI) to a processed insulin analog (Human Proinsulin having Lys at position 28 and Pro at position 29 of the corresponding insulin B-chain, KPB-hPI).

Abstract: For injection molding of tooth brushes a mold with two relatively movable mold parts (10, 12) defining a mold cavity (14) is used. One of the mold parts (10) has tuft insertion holes (16) therein. After tufts of bristles (18) have been introduced into the tuft insertion holes (16) so that they have an end projecting into the cavity portion (14a), the projecting bristle ends are exposed to heat to form individual knobs of molten bristle material at the end of each tuft. The mold is closed and plasticized molding material is injected into the cavity and around the knobs of molten bristle material. To prevent the bristles of thus embedded tufts from spreading open, the tufts with the knobs formed on their inner ends are pushed deeper into the molded material, simultaneously preventing plasticized molding material from leaking out of the cavity. <IMAGE>

Abstract: A digital video, audio and data distribution system which enables a set-top terminal (STT) associated with a customer's television set or other information presentation device to request interactive digital video, audio and data services from a service provider (SP) through the use of control system messages transmitted via a hi-directional signalling path. The requested interactive service is transmitted from the service provider over a portion of the bandwidth of a broadband transmission network which is dedicated to interactive digital services. A Video Session Connection (VSC) is provided for setting up and maintaining interactive sessions between the set-top terminal and a video service provider during the time the interactive programming is provided to the customer. The set-top terminal and service provider establish the Video Session Connection via a two-way signalling path within the bandwidth of the transmission medium into the customer's home. Applications of the system of the invention include "movie on demand" services where the set-top terminal not only requests a movie to be transmitted from the service provider for immediate transmission, but also the bi-directional command channel permits the set-top terminal to control the video presentation by sending commands such as Play, Pause, Fast-Forward and the like to the Service Provider while the movie is being transmitted. Other applications of the invention include on-line data retrieval services, shop at home services and other services which require the use of an interactive connection.

Abstract: An inspection system for sampling and determining the presence of residues of contaminants within plastic materials to be recycled from used plastic materials such as plastic beverage bottles or plastic food containers includes a chemical sniffing apparatus, or alternatively an optical scanner, for detecting the contaminants as the plastic materials are rapidly moved along a conveyor past a series of stations. Recycled food or beverage bottles are fed through a shredder in-line with the conveyor and the shredded plastic material from the bottles is fed to a washer. The bottles and shredded material may be tested for contaminants at any location in an in-line process. In one exemplary system first the bottles are tested prior to entry into the shredder in order to remove bottles containing gross contaminants. Second the shredded material emerging from the shredder is immediately tested for contaminants at an elevated temperature caused by the shredding process and contaminated materials are separated or sorted out from the uncontaminated material. Third, the materials are again tested for contaminants as they emerge from the washer once again taking advantage of the elevated temperature of the materials which is conducive to the emission of vapors of the contaminants. Contaminated materials are again sorted from the uncontaminated supply of materials to be used for the fabrication of new plastic food or beverage bottles.
