A method of applying a material comprising a fusible polymer comprises the step of: applying a filament of the at least partly molten material comprising a fusible polymer from a discharge opening of a discharge element to a first substrate. The fusible polymer has the following properties: a melting point (DSC, differential scanning calorimetry; 2nd heating at heating rate 5° C./min) within a range from ≥35° C. to ≤150° C.; a glass transition temperature (DMA, dynamic-mechanical analysis to DIN EN ISO 6721-1:2011) within a range from ≥−70° C. to ≤110° C.;
wherein the filament, during the application process, has an application temperature of ≥100° C. above the melting point of the fusible polymer for ≤20 minutes. There are furthermore blocked NCO groups present in the material comprising the fusible polymer.

A method for forming a multilayer plastic sheet material is disclosed, where a first polymer mass is melted under pressure and is passed through an extruder head at a specified discharge rate in the form of a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed. This is passed to two or more rolls of a finishing stand that processes the multilayer plastic strand into a sheet. After the plastic strand in sheet form leaves the extruder head, it is first passed between a top roll and a bottom roll of a roughing stand. The speed of the rolls of the finishing stand and the rolls of the roughing stand is synchronized with the discharge rate of the plastic strand in sheet form from the extruder head, so that the plastic strand is processed without stress.

A casting mold for producing a casting having a front side and a rear side from a curable casting compound, including at least a first mold part shaping the front side and a second mold part shaping the rear side, the mold parts together delimiting a casting cavity. The first mold part has a first metal layer delimiting the casting cavity and the second mold part has a second metal layer delimiting the casting cavity. At least one metal layer is at least partially deformable for the purpose of changing the casting cavity volume. At least one mold part has an areal intermediate layer which is composed of an elastically deformable and compressible material and against which the metal layer of the mold part is movable with build-up of a restoring force on the part of the deforming intermediate layer.

A face shield, patient interface and methods of use thereof are described for improved respiratory therapy of patients. In particular, a face shield is disclosed that acts as a seal when used with a patient interface. The face shield may be manufactured from a low melt temperature hard thermoplastic material. The face shield may be formed initially formed to match the general contours of the face, but not customised to a specific user's face. The face shield may be crosslinked to provide shape memory to the seal and to improve its handling properties and is configured to be thermoformed to a user's face. The face shield may be customised to the patient's facial features to a second customised shape.

A non-conductive rubber hose is provided exhibiting lower conductivity compared to conventional EPDM hose, and reduced stiffness compared to conventional non-conductive thermoplastic hose. The hose is useful for applications such as in hydraulics for boom trucks, and for coolant in plasma cutting tools.

Process for manufacturing an applicator (3) comprising a loading/application part (4), with the succession of steps a/ a mould is provided, b/ thermoplastic elastomer material (M) with a hardness before injection of between 5 Shore A and 70 Shore A and inert gas (G) suitable for a physical foaming process are provided, c/ they are mixed, d/ the mixture is injection-moulded in the mould, e/ after the thermoplastic elastomer material has cooled and physical foaming thereof has been carried out, the filler/application part (4) which has an inner structure (11) with closed cells (11a) and a microporous surface structure (12) is removed, and with the absence of a step of depositing on the microporous surface structure (12) a flock or flock adhesion material.

A vehicle-window glass assembly includes a vehicle-window glass and its injection-molded encapsulation; and an over-molded bolt including a base, a thread rod and an injection-molded part. One end of the thread rod is fixedly connected to the base, and the injection-molded part covers at least a part of the base. The injection-molded encapsulation covers at least a part of the injection-molded part such that the over-molded bolt and the vehicle-window glass are fixed to each other, and a material of the injection-molded part has a tensile strength greater than that of a material of the injection-molded encapsulation. This vehicle-window glass assembly can b e adapted to various vehicle models with a large gap between a surface of a vehicle-window glass and a vehicle-door sheet metal on which the vehicle-window glass requires to be mounted.

The sensor housing of the present invention comprises a body and a gasket providing complete sealing within the body. The body comprises a lateral protrusion defining a first side, a second side generally parallel to the first side, and a third side connecting the first side and the second side. The gasket comprises a first leg portion, a second leg portion and a connecting portion. The first leg portion and the second leg portion extend in opposite directions. The connecting portion extends laterally to form a bridge between the first leg portion and the second leg portion. Further, the connecting portion and the second leg portion enclose the first side and the third side of the lateral protrusion, leaving the second side unenclosed by the gasket. The first leg portion comprises a first protrusion and a second protrusion extending outwardly and laterally in the same direction.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.
