Patent AT-E54676-T1 (AT)
Inventor: ANDERSON DIANA MARY
IPC: C22B34/36

Abstract: The scarcity of high grade tungsten ores obliges users to seek to recover it from scrap materials, but drill bits in particular pose especial problems. Existing proposals to use acidic hydrogen peroxide to oxides and solubilize tungsten is extremely inefficient in reagent consumption per unit tungsten recovered. According to the present invention, hydrogen peroxide can be used considerably more efficiently in the extraction of tungsten into an aqueous acidic solution by employing certain promoters which are solid at 50 DEG  C. in the form of fused blocks. These blocks release the promoter slowly into the reaction solution and achieve similar efficiency of use of hydrogen peroxide and acid but at markedly reduced consumption of promoter in comparison with the same promoter added in powder or granular form. Examples of such promoter are hydroxy or amino substituted aromatic carboxylic acids e.g. 2-hydroxybenzoic acid. The promoters can most conveniently be used in a multi-stage tungsten extraction process.

Abstract: A rotary packaging machine advances carton sleeves (2) stepwise through a series of stations at which various operations are performed in relation to the steeves. At certain earlier ones of the stations operations are performed upon the bottoms of the sleeves at a desired common level. At certain later ones of the stations operations are performed upon the tops of the sleeves at a higher desired common level. At one station intermediate the earlier ones and later ones, the sleeves are lowered by an amount dependent upon their heights, so as to bring their tops to that higher desired common level.

Abstract: In oder to improve fixing between an electronic module (140) and the body (120) of a credit card made of plastic material, a housing (122, 134) is provided in the card body with bumps (130, 132) projecting into the housing. The electronic module (140) is pressed against the bumps (130, 132) while being raised to the softening temperature of the material from which the bumps are made. The module is pressed until its contact tabs (148) are level with the face (126) of the body. Fixing is completed by causing a glue to penetrate by capilarity between the bottom (124), the insulating substrate (142) of the electronic module, and the bumps (130, 132). The invention is particularly applicable to prepaid credit cards.

Abstract: A still image pickup camera has a solid state image pickup device (1) comprising an image pickup area (2), a temporary storage area (3), and a horizontal shift register (4). The signal charges in the image pickup area are transferred to the temporary storage area by the transfer pulses (P1) which are given for a vertical blanking period. Clear pulses (CP) which are equivalent to the transfer pulses are given at a desired timing in the interval between the vertical sync signals (VD) so as to enable the photo sensing interval (storage interval) in the image pickup area to be reduced and varied, thereby transferring the signal charges in the image pickup area to the temporary storage area and clearing the image pickup area.

Abstract: Method and apparatus for preventing bed sores in a bedridden patient (348). A low air loss bed is provided including a frame (12), a first set (321) of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame (12), and a second set of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame (12), and all of the air bags are connected to a gas source. The conformation of the air bags is such that, when the first set of air bags is inflated, the patient (348) supported thereon is moved toward the first side of the frame of the low air loss bed and, when the second set of air bags is inflated while the first set of air bags is deflated, the patient is moved toward the second side of the low air loss bed. The conformation of the air bags also retains the patient on the top surface of the air bags when the patient is rolled in one direction or the other. The first and second sets of air bags are mounted on a frame (12) which is itself divided into sets of transversely mounted air bags so that the frame can be contoured to the patient's comfort. Also provided is means for additionally inflating the air bags under those portions of the patient which are heaviest when the frame of the bed is inclined for patient comfort. The method of the present invention comprises inflating a plurality of air bags to a selected pressure for supporting a patient (348) thereon, inflating a first set of air bags to a pressure higher than the selected pressure to cause the patient support thereon to be rolled in a first direction on the air bags, and thereafter deflating the first set of air bags while inflating a second set of air bags to a higher pressure than the selected pressure to cause the patient (348) to be rolled in a second direction on the air bags. A third set of air bags can be provided in which the selected pressure is maintained, thereby substantially immobilizing a portion of the patient's (348) body.

Abstract: The invention relates to a process for dividing up and recovering the individual materials from old cables. For this purpose, the cable mixture is sorted into individual constituents and cut to size, the outer plastic sheath is removed by being slit open, and the individual cores are fed to a disk comminuter. It is essential, at the same time, that the disk comminuter should cut up the individual plastic-sheathed cables or the cable composed of several individual cables into short cable pieces of a length of 3 to 10 mm in a salami-like manner. Because the pieces are very short, the short cable pins are separated from the plastic ring arranged round them on a following vibrating screen.
