Title: Method of producing a print forme on a forme cylinder using a laser image-application process
Inventor: GOETTLING JOSEF
IPC: B41F13/10
Filed: 1998-10-09
Abstract: The method includes the steps of mounting a hollow foil body (3) on the forme (2) or forme cylinder (1), either by applying a ready formed hose or by wrapping the forme with a foil sheet. Then, producing an image on the forme by transferring surface elements of the foil hose (3) by heating using a laser beam, and removing the foil body (3) from the forme cylinder (1).  The foil body is in the form of a hose, and the hose is widened by means of heated compressed air for mounting on to the forme cylinder, and is subsequently fastened by stopping the compressed air. The excess hose is cut off, or correct length hose may be used. The compressed air is supplied via blow holes (20) in the forme cylinder, and compressed air may be introduced into the section of hose which is not yet mounted. In another method, an oversize foil tube is placed over the forme cylinder, and is brought by means of pressing rollers into rolling contact with the forme or forme cylinder so that it adheres. Application of the foil body to the forme can be either inside or outside the printing machine. An Independent claim is also given for an apparatus to produce an image on the cylindrical forme.

Title: PET bottle preform injection molding machine employs valved pneumatic piston for ejection and reduced pressure for molding induction, and cooling jacket
Inventor: WEINMANN ROBERT
IPC: B29B11/08
Filed: 1998-10-22
Abstract: The piston (203) opening includes a sliding valve rod (204). There is a passage (202') between air chamber (27) and internal molding volume of the cooling jacket (200). When reduced pressure is applied in the air chamber, the passage communicates it into the molding volume, drawing in the molding. When overpressure is applied to the chamber, the molding is ejected by the piston.  Preferred features: The passage between the interior of the cooling jacket and the air chamber is formed by defined clearance between piston and inner wall of the opening, in which the piston slides axially. On pressure application, the piston slides into the molding chamber, seating on a defined shoulder. This arrangement is further detailed. The valve guide opening (202) is grooved to form a communicating passage. This is opened on reducing the pressure in the air chamber. The valve seat is conical.

Title: Drive for a multi-head embroidery/sewing machine has a common main shaft with an asynchronous motor at each head to drive the shaft with a controlled torque twist on the shaft
Inventor: STEINKI KARL
IPC: D05C3/02
Filed: 1999-03-18
Abstract: The drive for a multi-head embroidery or sewing machine has a common main shaft (2) to power the heads (1). A number of asynchronous motors (3) drive the main shaft (2) with their drive torques distributed along the shaft (2) length.  The drive torques of the asynchronous motors (3) are distributed at equal intervals over the shaft (2) length. An asynchronous motor (3) is fitted to every second, third or fourth embroidery head (1), with the drive torque transmitted to the shaft (2) in the direct vicinity of the head (1). The main shaft (2) forms the rotor of the asynchronous motors (3). A gearing is between an asynchronous motor (3) and the main shaft (2), where the motor torque is transmitted to the shaft (2) by a belt, chain and/or toothed belt. The motors (3) are switched together electrically, and are controlled by an amplifier. The cross section of the main shaft (2) is sufficiently thin so that the torque twist on the shaft (2) between motors (3) does not exceed a permissible value. The asynchronous motors (3) and/or main shaft (2) drive the loopers or shuttles (8) through a gearing (6,7) such as a belt, chain and/or toothed belt. A sensor monitors the drive torque on the main shaft (2) at least at one point, linked to a control to reduce the torque twist on the shaft (2). The main shaft (2) has a number of sections, each for an asynchronous motor (3) and an embroidery head (1). The shaft sections are coupled together, especially by flanges and particularly rigidly screwed together.
