Patent EP-0289353-A3 (EP)
IPC: C07K1/04
Filed: 1988-04-29
Abstract: A novel method of activation of a protected amino acid using 
Benzotriazolyloxytris(dimethylamino)phosphonium Hexafluorophos­
phate (BOP) as an activator for solid phase peptide synthesis is 
provided. Hydroxybenzotriazole is included in preferred embodi­
ments. An intermediate acyloxyphosphonium salt is formed from the 
protected amino acid and the BOP which immediately reacts with HOBt 
to form an ester without formation of the less reactive symmetrical 
anhydride. A tertiary of quaternary substituted nitrogen compound 
must be used to produce a carboxylate of the protected amino acids 
as it also functions to increase their solubility.

Filed: 1989-08-11
Abstract: In a control system for synchronous rotation of the cutter 
heads in a multi-cutter shield machine, the rotating cutter 
heads are so disposed in generally same planes that the dis­
tance between the centers of the adjoining cutter heads is 
larger than the radius, and smaller than the diameter, of the

motors with a reduction gear, coupled to the respective rotat­
ing cutter heads by means of a pinion and gear. The motor 
rotation is so controlled and the cutter heads are so syn­
chronously rotated, that the angle of deviation between the 
cutter heads is within such an allowable range that the cutter 
heads will not interfere with each other even if there is any 
imbalance in excavating and rotating resistances between the 
cutter heads.

Patent EP-0335613-A3 (EP)
IPC: C08L23/06
Filed: 1989-03-23
Abstract: Porous shaped articles made from a molded composite of ultra high molecular weight polyethylene and polyethylene wax are disclosed. These articles are produced by free-sintering a non intensively mixed blend of UHMW-PE particles and particles of a polyethylene wax. The process involves mixing the UHMW-PE and wax both in powdered form until a heterogeneous mixture is formed, but under conditions which do not lead to any substantial fracturing of the UHMW-PE particles or melting of either component. The heterogeneous mix is then transferred to a press mold to form a shape and pressure is applied sufficient only to maintain the enclosed volume of the shape. The mold is heated to a temperature above the melting point of the UHMW-PE for a period of time to allow the particles to soften, expand, and contact one another at their surfaces. The mixture is then quickly cooled. Porous articles so produced may exhibit stiffness values in excess of about 2000 psi while at the same time showing excellent porosity values of less than about 25 inches water pressure drop.
