摘要:
The formation of inactive, insoluble forms of peptide can be minimized or, alternatively, inactive, insoluble forms of peptide compounds, if present, can be converted into more physiologically active, soluble forms by dissolving peptide samples in aqueous base and then acidifying the aqueous mixture to precipitate the peptide in the presence of at least one of a salt and a co-solvent. Preferably, both a salt and co-solvent are present. By carrying out the precipitation relatively rapidly (at least in a first stage of acidifying in which the pH of the alkaline medium is reduced to a pH in the range of 6 to 7.5, after which acidification to a final desired pH, e.g., 3 to 6, can occur more slowly) at relatively low temperature, the dissolution characteristics of the resultant precipitated peptide are even further improved. The process is robust, consistent, and suitable for commercial scale manufacture of peptides.

摘要:
A special angle beam probe for ultrasonic testing includes at least one ultrasonic vibrator fastened in a beam probe housing on a wedge-shaped support body which may be formed of Plexiglass, using damping means. The ultrasonic beam of the vibrator strikes the surface of the test piece at an incidence angle other than 0.degree., as measured from a perpendicular at the surface of the test piece at the point where the beam strikes. The ultrasonic beam furthermore strikes the test piece surface at an oblique angle between 0.degree. and 360.degree. subtended between a principal beam probe axis and the beam, as seen in the direction perpendicular to the beam probe from above. The novelty of the invention is that the special angle beam probe includes a multiplicity of prefabricated beam probe subassemblies. The ultrasonic vibrator of each subassembly is fastened with a predetermined incidence angle within a first beam probe housing. A second beam probe housing contains the test head subassembly and the test head subassembly can be fastened at least at one predetermined oblique angle within the second housing for forming the overall special angle beam probe. In this way a multiplicity of beam probe subassemblies with the same insonification angle form special angle beam probes with different, predetermined oblique angles, by assembling the subassemblies in second test head housings in different oblique angle relationships.

A document processing system for performing multiple document processing tasks while the documents travel in a straight line document path is provided. The document processing system may include a transport system for transporting the documents in a straight line path, a sensing system for sensing the presence of the document, an optical system for projecting the image of the document, a camera module for receiving the projected image and storing it onto film, a film marking system for placing blips on the film adjacent the document image, a film numbering system for placing alphanumeric characters on the film adjacent the document image, an endorsing system for placing a printed endorsement on one side of the document, an electro-optical scanning system for scanning the image of the document processing the signal into a bit mapped image or for use with external communications devices, scanning for bar code symbology, and imprinting characters on the documents.A machine having a transport system to serially move documents in a straight line path and having one or more of the systems is provided and can be serially linked to another like machine so that the exit of a first machine is the inlet to the second machine.
摘要:
A failsafe weld-free method of joining tubular elements provides for connecting a first tubular element to a second tubular element. The assembly includes an insert, with screw threads, inside of the first tube, a connector fitting for mounting to the insert within the first tube by a screw, a second tube is secured to the connector fitting with a fastener through a transverse hole through both the second tube and the connector fitting. When the connector fitting is assembled to the first tubular section and the connecting screw is tightened, a structurally rigid connection is achieved. The second tubular section is positioned over the stepped outside diameter of the connector fitting, aligning the transverse holes. A fastener is installed through the transverse hole. The fastener that secures the connector fitting to the second tubular section is positioned to not allow the screw fastening the connector fitting to the first tubular section to disengage or loosen. The resulting joint is structurally rigid in all planes without a visible fastener on the first tubular section with no distortion to the tubing due to bolt torque.
摘要:
A wheelchair assembly which can be quickly and inexpensively assembled and disassembled is described which is formed of tubular members which are secured only with clamping members to produce a rigid frame wheelchair. No welds are utilized, the clamps being formed of molded composite material, such as a carbon fiber-filled polyamide. Each clamp is formed of complimentary shells formed with semi-cylindrical regions dimensioned to receive, between two mating complimentary members, cross tubes to be secured in pressure fit relationship.
