Abstract: The invention relates to a method of sorting cutlery, comprising opto-electronic dynamic recognition and identification of the cutlery. The pieces of cutlery are brought forward in a longitudinal direction one by one behind each other on a moving conveyor belt (12). The movement of the belt is precision linked to a pulsator (13), which emits pulses with a frequency that is directly proportional to the speed of the belt. The pieces of cutlery are brought by the conveyor belt to pass one by one through an optical read-off unit (14) between a light source (32) and a bar (40) of photo-transistors (33) or light-conductors (38) which transmit light to photo-transistors. The bar extends at right angles to the direction of movement of the belt, so that it is partially shaded by the cutlery when this passes, whereupon the photo-transistors in the parts of the bar shaded at any moment are inactivated.

Abstract: The invention relates to a device comprising a mattress support intended to be placed underneath a mattress or the like, to facilitate the care of bedridden patients. The support consists of a number of sections (1), each comprising a rigid board (4) or the like, extending essentially fully across the width of the support, and underneath each such board at least two inflatable cells (13a, 13b), of which at least one is placed on each side of an imaginary center line (14) along the support (21).

Abstract: The invention relates to a device for adjusting the backrest, preferably of vehicle seats. It is characterized by a first plate-shaped portion, which by a belt-like member is connected to a rigid part of one lateral edge of the seat back, and a second plate-shaped portion, which by a belt-like member is connected to a rigid part of the second lateral edge of the seat back. The plate-shaped portions are located with their plane sides facing to each other, and a spring means is provided to stretch the belt-like members between the lateral edges. A holder-on member is located outside the plate-shaped portions and receives a means intended as desired to press the plate-shaped portions into locking engagement with each other and, respectively, with the holder-on member.
