摘要： The ear plug (40) includes an elongate body with a rounded tip portion and of an elastic material enveloped by a deep-drawn sheath (41) of thin flexible plastics film material. Rearwardly the plug preferably has a neck portion from which the sheath projects in the form of a stiffer collar or flange. Production of the ear plug includes deep-drawing a thermoplastic film or foil into a sheath with desired thickness distribution, and filling the sheath with elastic material (53). Filling may take place simultaneously with deep-drawing, the body of elastic material constituting a die for deep-drawing in a forming hole (45), or after the deep-drawing. In the latter case, an elastic die body is used to advantage, the shape of which generally corresponds to that of the finished plug, for deep-drawing in a forming hole suited to the die body.

摘要： An ear-plug comprising a plug-like body of fine glass wool and a surrounding casing of thin polyethylene film having low friction vis-a-vis the auditory canal. The glass wool is exposed at the surface of the expanded end of the ear-plug not to be inserted into the auditory canal. The ear-plug is fixed as to shape by means of a circumferential heat weld in the polyethylene film located where the expanded part of the ear-plug begins.

摘要： Two, endless, perforated steel belts are mounted one above the other to travel about spaced rolls, and between a pair of spaced, parallel, stationary side walls, so that confronting portions of the belts form two sides of an elongate, rectangular channel. Granules of thermoplastic material are continuously fed into one end of the channel in a quantity sufficient to completely fill the channel. The moving belts convey the granules first past a heating zone, where steam is introduced through the perforated belts to cause the granules to expand, and then past a cooling zone, where the granules are sintered to form a solid, rectangular block which is discharged continuously from the opposite end of the channel and onto a surface where it is severed into individual blocks. The diameters of the holes in the belts range from 0.5 to 0.8 mm., and the number of holes ranges from 20,000 to 30,000 per square meter of belt.

摘要： An attachment device in the form of a bearing housing (10) and an arm (38) projecting out through an opening (44) in the housing. The arm is supported in a bearing support (42) in the housing and serves to carry, at the end opposite the housing, an ear muff to move with a rocking motion between a stationary rest position and a position wherein the earmuff exerts a pressure around the wearer's ear. A separate spring component (44), preferably annular in form, is rotatably supported in and prestressed to bear against, on one side, an adjustable spring support (48), which is located inside the housing and remains stationary during the rocking motion, and, on the opposite side, the end (52) of the arm (38) located inside the housing. By this arrangement there is exerted on the said end of the arm a controlled force directed away from the spring support (48) for the purpose of stabilizing the arm in its two positions. The spring support may consist of a rocker, the position of that part (56) of the rocker in which the spring component is supported being adjustable against an adjusting means (16) with respect to the nearer end of the arm to permit alteration of the prestressing of the spring component. The adjusting means consists of a cover (16) with an annular collar (30) of thickness varying along the extent thereof. The collar rests against the inside of the ring flange (32) of a base (12), which is rotatable with respect to the said adjusting cover.

摘要： A tubular filter which is primarily intended for filtration of liquid flowing substantially radially towards the interior of the filter. The filter comprises two layers (10, 11) of mineral wool. An interior layer (10) has the fibres oriented substantially concentrically to the tube axis and an outer filter layer (11) of mineral wool has the fibres oriented substantially radially to the tube axis. The material of the tubular filter must be arranged so that its density increases from the outer portion of the tubular filter towards its inner portion.

摘要： The invention relates to a method and an apparatus for compressing voluminous material easy to compress and for storing and transporting the material in said compressed state. According to the invention, thus, there are provided a bottom and two opposed vertical walls capable to approach each other for compressing the material between the walls. When the material has been compressed to the desired volume the material is transferred to a storage or transport crate, which is located with its floor beneath the bottom and with its sides outside of and adjacent the walls. When the material is being discharged between the walls, it expands and presses against the side of the crate and an end side connected to the crate whereby the crate is moved with the material while being successively filled. When the material is being compressed it is pressed downward by a belt acting from above on the material.
