Title: Incontinence pad mfg. appts. - uses heat source and roller pressure to produce layers of varying thickness and absorbency
IPC: A61F13/15
Filed: 1989-10-24
Abstract: Material (5) of constant thickness is absorbent. The bottom layer (6) is of impermeable material while the top player (16) is liquid-impermeable. The absorbent layer is subject to a heat source (7) and to pressure (8) to achieve the required adhesion. Pressure is applied by roller (9) rotating on a shaft (10) which is movable up and down w.r.t. the centre line (11). Opposite this roller is a second roller (12). In the nip between the rollers runs a support layer (13), on top of this a rear layer, then a layer of absorbent material, then the top layer. When the nip is at max. the absorbing layer is at min. (14). When the rollers rotate half a turn the nip is max., thus producing a thicker section (15). A cutter roller (17) has a knife (18), and its circumference is equal to the distance between the thin area (14), thus material is at thinnest section of material length.

Patent NL-9201593-A (NL)
IPC: H04N13/00
Filed: 1992-09-14
Abstract: Known systems based on stereoscopic video coding and video decoding code with inadequate efficiency because the left-hand picture and the right-hand picture are coded and decoded independently of one another by means of the encoders present in the system. As a result of providing one encoder with switching means to which a signal representing the left-hand picture and a signal representing the right-hand picture are fed, said encoder is able to base the prediction either on the left-hand picture or the right-hand picture, and this improves the prediction and, consequently, the efficiency of the coding. As a result of designing the switching means, according to one embodiment, for the adjustment of the ratio of the signal representing the left-hand picture and the signal representing the right-hand picture and for the subsequent addition of the two adjusted signals, a still greater advantage is achieved in the prediction with the correct ratio, and this results in a further improvement in the efficiency of the (total) coding. <IMAGE>
