Abstract: Some embodiments of disclosed pillow comprise a first sleeve within which is retained a plurality of loose pieces of filler material, a second sleeve in which the first sleeve is received, and a unitary piece of foam retained between the first and second sleeves. In some embodiments, the unitary piece of foam comprises viscoelastic foam, and can be elongated to run along a side of the first sleeve, can be substantially flat to cover a face of the first sleeve, or can take other shapes and be located in other positions as desired. Also, in some embodiments the unitary piece of foam is shaped to mate with the first sleeve. Additional unitary pieces of foam can be located adjacent the first sleeve and can be retained between the first and second sleeves to provide pillows having other support and cushioning characteristics.

Abstract: Some embodiments of the disclosed pillows have a sleeve of viscoelastic material within which is received and enclosed a plurality of loose pieces of filler material. The sleeve can have one or more openings shaped and dimensioned to provide ventilation for the interior of the pillow and/or to enable a user to insert and remove an inner sleeve within which the filler material is retained. In some embodiments, the inner sleeve has two or more compartments for holding the same or different filler materials having the same or different densities, thereby providing a pillow adapted for different uses and support characteristics.

Abstract: Non-woven materials from polyolefin-based fibres which have bulk and resilience comparable to polyester fibres are described herein, thus expanding the utility of polyolefin fibres and nonwovens to a plethora of industrial applications which previously excluded products based on polyolefin fibres due to their hitherto inadequate bulk or resilience. Control of polyolefin fibre characteristics such as the fibre/fibre friction, fibre crystallinity, draw ratio, or selection of the spin finish so as to comprise essentially of an aqueous emulsion of polysiloxanes render them suitable for preparing bulky and resilient nonwovens.

Abstract: For a roller blind, particularly for use as a blackout shade, and with a spring-biased roller bar and a blind rolled on the roller bar and having along its lateral edges guide members guided in tracks in guide rails disposed at both sides of the window opening, and a bottom bar, a brake device is provided for retaining the bottom bar in an arbitrary position against the effect of the bias-force by a cord arrangement with a cord which at the bottom of one guide rail is passed through the guide rail, the bottom bar and the other guide rail to a fixture at the top thereof. A friction mechanism acting on the cord two pins is mounted in the bottom bar over which the cord is passed in S-shape. To ensure parallel guidance of the bottom bar in relation to the roller bar the cord arrangement may include two cords mounted in mirror-inversion.
