Title: Peptides useful for inducing tolerance
Inventor: GEFTER MALCOLM L
IPC: C12N15/12
Filed: 1993-03-25
Granted: 2012-10-16
Abstract: The present invention is based on the discovery that subcutaneous administration of a peptide comprising at least one T  cell epitope of a protein allergen or other protein antigen results in T cell tolerance upon subsequent exposure to the allergen or other antigen. Peptides useful for inducing tolerance in a mammal, such as a human by subcutaneous administration or other routes of administration are within the scope of this invention. Such peptides include peptide X (SEQ ID NO: 7), peptide Y  (SEQ ID NO: 8), peptide Z (SEQ ID NO: 9), peptide A (SEQ ID NO: 10), peptide B  (SEQ ID NO: 11), peptide C (SEQ ID  NO: 12), peptide D (SEQ ID NO: 13), and peptide E (SEQ ID NO: 14), each as shown in the figure. It is preferred that such peptides be administered in soluble form.

Abstract: Embryogenesis from plant microspores can be induced with a 24 h temperature treatment of 32.5°C. Continuous culture at 25°C  results in pollen development. However, in this study, microspore treatment by microtubule inhibitors, at the non-inductive temperature of 25°C, can induce embryogenesis, thus demonstrating that heat shock is not required for embryogenic induction. A great advantage in using microtubule inhibitors is that induction and chromosome doubling can occur simultaneously, thus generating doubled haploids, whereas heat induction generates haploids. Thus, the use of microtubule inhibitors will provide a simple one-step process to simultaneously induce embryogenesis and chromosome doubling for the production of fertile plants, thus providing minimal manipulation which will be very advantageous for genetic studies and plant breeding programs. As noted, heat shock induction induces haploids. Chromosome doubling can be induced by colchicine. However, the application of trifluralin to embryogenic microspore cultures to generate doubled haploid plants results in an improved recovery of fertile doubled haploid plants than previously shown in the prior art.

Abstract: A process of producing an aqueous solution of a sulfonated melamine-formaldehyde resin. The process condensing melamine and formaldehyde or a precursor of formaldehyde (e.g. paraformaldehyde) in an aqueous mixture having a pH in the range of 8-10 to form a reaction mixture containing a condensation product of melamine and formaldehyde.  The condensation product is then reacted in an aqueous mixture having a pH of 8-10, preferably 8-9, with a sulfonating agent to produce a mixture containing a sulfonated condensation product. Finally, polymerizing the said sulfonated condensation product in an aqueous mixture having a pH of 5-7 to form a resin solution. In the process, at least one of the sulfonation step and the polymerizing step is carried out under superatmospheric pressure (generally 35 to 483 kPa (5 to 70 p.s.i.)) and at an elevated temperature of, in the case of the sulfonating step, 100-130 °C for a time of 1/2 to 3 hours or of, in the case of the polymerizing step, 100-150 °C for a time of 15 minutes to three hours. Modification of the basic process involve carrying out the sulfonation of the formaldehyde before the condensation of the melamine and formaldehyde or reacting all of the melamine, formaldehyde or precursor and the sulfonating agent all together under superplasticizer pressure. The resulting aqueous solution, or the dried resin extracted therefrom, has low salt content and is suitable as a superplasticizer for concrete mixes.

Title: Servo plunger mechanism
Inventor: LEIDY D WAYNE
IPC: C03B11/16
Filed: 1996-12-13
Granted: 2002-04-23
Abstract: A plunger mechanism for forming a hollow article of glass in a "narrow neck press and blow" operation which utilizes an electro servo-driven leadscrew to actuate it.  A position sensing resolver is used to determine the position of the plunger over the full range of its stroke, and the position information can be used as feedback to control the position of the plunger prior to contacting a molten gob of glass in a mold chamber.  The depth of the plunger penetration into the molten gob is then controlled by the pressing pressure, which is a function of motor torque and screw mechanics.  It is possible to control the pressure exerted on the molten glass gob by controlling the torque applied by the motor.  A separate gob weight controller is not required because changes in gob weight can be determined by closely monitoring the plunger penetration of the gob.
