Abstract: A dispenser for a fluid material includes a handle portion and a cartridge having the material to be dispensed. The cartridge is easily mounted to the handle portion or removed, whereby the handle portion may be used with a variety of cartridges, each of which may contain a selected material. The handle portion includes a plunger that is moved linearly by actuation of a trigger mechanism, which is engaged by a user's finger. The trigger mechanism is configured to release pressure applied to the plunger quickly upon release of pressure on the trigger and to allow the plunger to move away from the cartridge to ensure release of pressure in the material to be dispensed to prevent dripping.

Abstract: A tubular printing blanket having an axial center has a carrier sleeve layer having a uniform thickness, a compressible layer, a reinforcing layer over the compressible layer, and a print layer disposed over the reinforcing layer. At least one of the reinforcing layer and the compressible layers has a non-uniform thickness so as to be thicker in the axial center. An outer surface of the print layer is convex.

Abstract: A printing blanket includes a carrier sleeve layer having at least one axially convex surface and a print layer disposed over the carrier sleeve layer. A blanket cylinder with a convex outer surface and a convex shim is also provided. An offset printing press is also provided.

Abstract: The present invention relates to a compound having antimicrobial activities. The present invention also provides methods for the production and purification of flocculosin, the antimicrobial compound of the invention, including the steps of cultivating the microorganism Pseudozyma flocculosa. Analogs and derivatives of flocculosin are described herein.

Abstract: A dispenser for a liquid or semi-solid material includes a container having a valve element at one end and a piston at the other. The valve element includes central and annular portions, the annular portion forming a good seal with the interior of the container and the central portion having a plurality of resilient flaps forming a valve. The dispenser is easily assembled because the valve element may be placed in the container without special tools or retaining structure, and the valve element is retained in place by the material. The valve element includes an annular sealing portion that flexes outwardly against the interior wall of the container during dispensing of the material. The central portion having the flaps is relatively thick to provide good restoring power to the flaps, and it is recessed from the front wall of the valve to provide space for the flaps to open when the valve is in contact with the front wall of the container.

Abstract: A printing unit including a rigid cylinder rotatable about an axis of rotation, a plurality of inflatable bladders disposed on a circumferential surface of the cylinder, and a first fluid supply regulation unit configured to supply a first fluid to a first set of inflatable bladders of the plurality of inflatable bladders and to regulate a first fluid pressure inside the first set inflatable bladders. In addition, a method for mounting a sleeve-shaped printing sock onto a blanket cylinder of an offset printing press, in which a set of inflatable bladders disposed at an outer region of the blanket cylinder are at least partially deflated. The sleeve-shaped printing sock is slid over one end of the blanket cylinder so that the printing sock at least partially surrounds a circumference of the blanket cylinder. The set of inflatable bladders are then inflated so that the printing sock fits tightly around the circumference of the blanket cylinder.

Abstract: A hand held hot melt glue gun has an elongate body portion that is easily held in a user's palm for accurate placement of the glue. The body forms a heat chamber that lies in the body parallel to the longitudinal axis of the body. A trigger mechanism operates by motion transverse to the longitudinal axis of the body and includes an arm that extends from the trigger on one side of the heat chamber to an opposite side of the heat chamber to engage a gripper for advancing the glue.

Abstract: A heating system for a hand-held glue gun has a low-mass melting chamber, high-power resistance heating element, and thermostat (24). The heating element is arranged between the chamber and thermostat (24), so that the thermostat's (24) response to the heating element mirrors that of the load in the chamber.

Abstract: The present invention relates to the use of Pseudozyma spp. for the production of recombinant polypeptides, proteins or peptides, by genetically transforming fungi with a plasmids or appropriate DNA expression vector.
