Title: Polymerisation of unsaturated monomers in solution with
Inventor: SVEN SOLVIK RAGNAR
IPC: C08F36/04
Filed: 1968-10-03
Abstract: A process for preparing polymers of mono- or poly-unsaturated aliphatic, aromatic or cycloaliphatic monomers by polymerising them in a solution of an inert volatile organic solvent of at least 15% solids content at a temperature sufficient to cause polymerisation and a pressure sufficient to keep the solvent in the liquid phase, heating the reaction mixture to a temperature and pressure above the critical part of the solvent and above the melting point of the polymer, rapidly reducing the pressure so that heat generated under isenthalpic conditions evaporates most of the solvent while the polymer remains above its melting point and is heated with agitation to remove the remainder of the solvent.

Patent DE-1938494-A1 (DE)
Title: Tire cord weft removal before entry into nip of - coating calendar
Inventor: ANTON STEINER DIPL-ING
IPC: B29C70/20
Filed: 1969-07-29
Abstract: A comb for the cord spacing is attached at the end of the roll of cord, and this comb is fed forward to the calender together with the leading edge of the cord fabric. Before the nip, the comb is trapped in a two-roll escapement system with stepped rolls, the leading edge of the fabric proceeding through the nip. On the let-off side of the comb trapping rolls is positioned a set of cutting knives, carried on a hinged mounting bracket which, at this point swings down and severs the weft between each cord. Between the knives and the trapped comb, through which the cord is now being drawn by the calender, is a brush and vacuum box to remove all remnants of the weft before the comb is entered. When the roll of cord is run out, the escapement rolls, rotate, rejecting the trapped comb, and a new comb is fed forward with the new roll, when the process repeats itself. The final guide comb may be held with retracting lugs rather than with escapement rolls, and a supplementary insertable comb may be inserted in the cords on the let-off side of the final comb.

Title: Machine for harvesting hay straw or similar crops - consists of tined wheel rotating on vertical axle which slopes forwards towards the ground
Inventor: WEIDTMANN RAINER DIPL ING
IPC: A01D78/10
Filed: 1974-03-02
Abstract: The tine attachments can pivot on a roughly tangential axis. A weight when in a non-operation position counteracts the weight of the tine. Alternatively, a plate spring prevents the tine from flapping back into place while being transported. Alternatively, magnetic attachment pieces or balls and pins hold the tines in a transporting position. The various pieces keep the tines in a high, inward pivoting position, when the wheel is not in operation. When the wheel begins to rotate, the resistance of these mechanical pieces is automatically overcome by centrifugal force, so that the tines assume a working position.
