Abstract: A method of making a glass laminated structure comprising retaining first and second glass panels against first and second platens respectively, using differential fluid pressure. The panels are held in spaced, generally parallel relationship and a curable flowable material is introduced into the space between the panels. The flowable material is then cured to provide the glass laminated structure.

Abstract: There is disclosed a positive extraction mechanism for use in a textile molding apparatus preferably of the type having a female mold member and a male mold member. The mold members move into molding relationship with a fabric therebetween to form a cup-like article which is retained by one of the members. The positive extraction mechanism moves into intimate contact with the retaining mold member after the other mold member has been retracted. The extraction mechanism includes a plurality of pins which may be actuated by power means into engagement with the molded cup-like article. Each pin is spring biased away from the molded article so that the spring will retract its associated pin within the extraction mechanism upon removal of the power means. Upon retraction the molded article will leave the positive extraction mechanism. This occurs after the molded article has been carried away from the mold member.

Abstract: A roll of controllable flexure having a cylindrical inner part and a tubular outer part surrounding the inner part and mounted rotatably at both its ends on the inner part. A heating strip is disposed along a generatrix on the inner part. At least one electrical temperature sensor is disposed in the inner part in the immediate vicinity of the heating strip and at least one additional electrical temperature sensor is disposed on the opposite side of the inner part. The two temperature sensors are connected to a temperature difference measuring apparatus and control an electrical regulating circuit to which a power circuit containing the heating strip is connected. The power delivered to the heating strip is so regulated that a preset temperature difference between the heated and unheated sides of the inner part is maintained. The different thermal elongation of the unheated and heated sides of the inner part produces an arching of the inner part which is transmitted to the outer part.
