Title: Metallurgical dust recycle process.
Inventor: DRINKARD WILLIAM F JR
IPC: C22B3/06
Filed: 1998-04-30
Abstract: A method and apparatus for the treatment and recovery of metal values from metallurgical dust comprising the steps of preliminarily washing of the dust to remove chloride salts (62), leaching the cleaned dust with a nitric acid solution resulting in the substantially complete dissolution of contained zinc, cadmium, copper, magnesium, calcium, manganese and lead values (64), collecting and recycling of exuded nitric acid fumes from the leach (92), removing iron from the resulting leachate as a reusable iron oxide precipitate via pH elevation with basic zinc carbonate (66), electrolytically recovering cadmium, copper, and lead from the iron free leachate (70), evaporating and decomposing the resulting anolyte to obtain oxides of zinc, magnesium, and manganese and anhydrous calcium nitrate (72), followed by calcium nitrate separation (74) and the ammoniacal dissolution (78) and recovery of zinc (84) with subsequent acid leaching (88) and separation of the magnesium and manganese values (90).
Patent MX-9903893-A (MX)
Inventor: CHIHANI THAMI
IPC: A61L15/42
Filed: 1997-10-17
Abstract: The invention relates to an absorption material (50; 60) comprising a carrier material exhibiting a coating (51; 61) of a thermosensitive polymer with a cloud point at a temperature in the vicinity of and somewhat below the body temperature of a healthy human being. The absorption properties of the polymer change at the cloud point, so that the polymer substantially lacks absorption capacity at a first temperature on one side of the cloud point but exhibits good absorption properties at a second temperature on the other side of the cloud point. Furthermore, the invention includes an absorbent article such as a diaper, an incontinence protector, a sanitary napkin, or the like, having an absorption body comprising an absorption material coated with a thermosensitive polymer.

Title: Continuous iron ore melt/purification process
IPC: C21C5/52
Filed: 1968-10-04
Abstract: Continuous process for melting and purifying previously heated and reduced oxydic ores in agglomerated or finely divided form, continuously fed into the arc zone of an electric oven, consists of melting and purifying in separate inter-connected melt, melt-out, purifying and slag settling zones in a single oven. Specif. turbulence and circulation provide a continuous flow from melt, melt-out into purifying zone. Circulation of the flow ensures low metal loss by continuous settling out of metal shot, and by applying a counter flow for the slag, forcing it to flow over the metal in purifying zone to provide additional iron extraction.

Title: Bird shaped diving instructional equipment - has hollow back accommodating pupil who causes unit to tip into diving position by raising arms
IPC: A63B5/10
Filed: 1978-03-10
Abstract: The diving appts. is particularly for teaching children to dive into water, and derives its diving movement from the fact that the pupil displaces his own body weight by making an upwards movement with his arms. This causes the position of the centre of gravity of the rotary part (1) of the equipment to be altered. This is turn causes the appts. to lose its equilibrium and perform the diving movement. No mechanical aid is involved in bringing about the rotary movement of the part (1) into question. The appts. conveniently has the form of a penguin with a hollow back (3) and a plate (9) on which it stands. The rotating part is attached by a rigid shaft (5) to a fixed base part (4) represented by the feet of the "bird".

Title: Microwave oven with outer and inner glass plates in door - having inner glass plate in loose fit to prevent abnormal heating problems
IPC: H05B6/76
Filed: 1983-08-15
Abstract: The oven door, pulled down to gain access to the heating chamber, consists of an outer wall incorporating a glass plate, and overlapping the aperture of the chamber and a smaller inner wall which makes a microwave tight seal with the chamber when closed. The inner wall consists of a metal surround (13), and another glass plate (15) which sits in a groove in the surround. The radius (R1) of the inside corners of the metal surround is greater than the radius (R2) of the corners of the glass plate. This difference allows for differential heating, the use of cheaper glass, less accurate assembly techniques, and also limits possible sparking or abnormal heating due to misalignment of the glass plate.

Patent NL-9100393-A (NL)
IPC: F16K/
Filed: 1991-03-05
Abstract: Valve comprising a valve stem and a valve disc. The peripheral edge of the valve disc in the closed position comes to rest in a sealing manner against the valve seat of the corresponding valve housing. Between this sealing peripheral edge and the valve stem the valve disc is partially made of elastically yielding material. The position of the valve stem guide is such that it is possible to move the valve further in the direction of closure after the peripheral edge rests against the valve seat. This means that a vacuum can be created with the aid of the valve according to the invention. Such a vacuum can be used in filling devices for drinks. The nozzle in this case is made of a relatively flexible material which closes when vacuum is created. In this way after-dripping of drinks in, for example, juice packs can be avoided.
Patent NL-9101898-A (NL)
IPC: A61F11/00
Filed: 1991-11-14
Abstract: A grommet at one side comprises a tubular part (3) which widens out either in a regular trumpet-shaped curve ("monotonic") or by means of one or more "steps" or "bends", with the result that the risk of blockage is considerably reduced and the grommet is less quickly expelled from the eardrum. At the other side the grommet is provided with a flange (2) by means of which the grommet remains hooked behind the eardrum. This flange (2) is so large - either round and the same size as the widely "fanning" top side of the trumpet-shaped top part (3) of the grommet, or provided with one or more symmetrical or asymmetrical projections - that the grommet is held fast by the eardrum for a relatively long time. A recurrence of the fluid accumulation in the tympanic cavity or of an ear infection is consequently less likely to occur. <IMAGE>
