A novel collapsible plant support includes a collapsible coil adapted to rest on a flat surface. In a particular embodiment, the collapsible plant support includes a plurality of vertical support structures coupled to the collapsible coil so as to provide additional support. In another particular embodiment, a collapsible plant support includes plant receptacle receiving element that supports both a collapsible coil and also a plant receptacle. In a more particular embodiment, the plant receptacle receiving element includes fluid ducts for connecting multiple plant receptacle receiving elements into a fluid network. In another embodiment, the coil is disposed within a helical sleeve coupled to a flexible, cylindrical mesh.

A method for producing a length-adjustable steering shaft having a hollow shaft in which a toothed shaft is received so as to be axially telescopic. The toothed shaft has a toothing with teeth on an external circumference that extend in the axial direction and which engages in a form-fitting manner in an inner toothing of the hollow shaft. A sliding layer of thermoplastic plastics material is at least in portions attached between the inner toothing and the toothing. In order to enable an improved fastening of the sliding layer to the toothing, prior to attaching the sliding layer, form-fitting elements which for forming a form-fitting connection that is effective in the axial direction are brought to engage with the sliding layer are configured in the region of the toothing of the toothed shaft or the inner toothing of the hollow shaft.

In an injection molded polypropylene field joint of an oil or gas pipeline, the three- dimensional geometry of the injection molded/cast coating can have an influence on the stress placed on the line coating during cooling. Specifically, it has been found that molding or casting a coating having circumferential grooves, or other groove geometry, proximal to the interface with the line coating, will reduce line coating failure proximal to the field joint, in particular line coating failure related to the initial spooling/reeling of the pipe.

A method for manufacturing a spline telescopic shaft according to the present disclosure includes a toothless portion forming step of forming a toothless portion in one of an external tooth of a shaft body and an internal tooth of a tubular body, a resin layer forming step of forming a resin layer by arranging one of the shaft body and the tubular body in a mold including a cavity and injecting a resin into the cavity, the cavity being included in a flat receiving surface that faces tooth flanks of one of the external tooth of the shaft body and the internal tooth of the tubular body, and a cooling step of cooling one of the shaft body including the resin layer and the tubular body including the resin layer to form a lubricant reservoir in the resin layer.

The invention relates to a method of manufacturing an air-intake duct (30) with induction noise and radiated noise attenuation that is intended to be connected to an internal combustion engine. The method comprises the steps of: (a): providing a mould (1) comprising two moulding cavities (2), each cavity (2) having at least one groove (4) adapted for moulding a rib (32) and having at least two half-bores (5) adapted for moulding end sleeves (34-36), (b): providing a core (8) adapted to be positioned between the cavities (2), for moulding an air-intake duct (30), (c): positioning a tubular layer (9) of air-porous material on the core (8), (d): positioning the core (8) with the tubular layer (9) between the moulding cavities (2), (e): injecting a thermoplastic material into the, or each, groove (4) and into each half-bore (5) of each cavity (2), in order to overmould ribs (32) and end sleeves (34-36) onto the tubular layer (9) so as to form a duct (30).

A padding device (10a; 10b; 10c; 10d; 10e), for a carrying belt system (100) for a respirator (1000), has a closed pad core shell (20) and a pad core (30) configured in the pad core shell. The padding device is formed by injection molding a hollow profiled section, inserting of a pad core material into the hollow profiled section for forming the pad core in the hollow profiled section, and closing the hollow profiled section (21) for creating the closed pad core shell (20). The padding device (10a; 10b; 10c; 10d; 10e) has a closed pad core shell (20) and a pad core (30) arranged in the pad core shell. The pad core shell is seamless as an injection-molded component in at least some sections. A carrying belt system and a respirator with the carrying belt system are provided with the belt system having the padding device.

Apparatuses and methods for on-line internal siliconing of glass bottles including a baking station for baking the siliconed bottles; wherein a siliconing station includes a support designed to selectively receive one bottle at a time, an injection device facing towards an inlet opening of the bottle, a mobile device for selectively blocking the injector against the inlet opening, a selective feeding device for feeding filtered compressed air and liquid silicone to the injector, the injector provided at the front, towards the support, with a drainage channel communicating with the inlet opening; an emitter to send towards a sensor and through the bottle on the support a beam of electromagnetic radiation; and a control unit to selectively inject into the bottle a mixture of silicone and compressed air and to process a signal emitted by the sensor to control the feeding device and/or a manipulator to discard defective bottles.

A method of protecting a layered coating on a length of pipe for subsea use includes applying an edge finisher to the coating to encase an edge of the coating by fusing the edge finisher with the coating or by moulding the edge finisher at an edge of the coating. Where the coating and the edge finisher are of thermoplastics such as PP, fusing can be achieved by injection moulding the edge finisher or by welding a discrete edge finisher component to the edge of the coating. Mirror welding may be employed for this purpose, with a hot plate being interposed between the edge of the coating and the edge finisher.
