Patent GB-2283622-B (GB)
Title: Overvoltage protection circuit
Inventor: MUDD MARK STEPHEN JOHN
IPC: H01L23/62
Filed: 1993-11-03
Granted: 1998-01-14
Abstract: An overvoltage protection circuit employs a series of semiconductor switching elements, each element having a control terminal and two main conduction terminals, in a totem pole configuration and two potential dividers whose tapping points feed, respectively, the control terminals and the main terminal junctions of the switching elements. Both the series of switching elements and the two potential dividers are connected between a reference node (zero volts) and a node to be protected from an electrostatic discharge. The resistive elements of the potential dividers are so arranged that, in the absence of a static discharge, all switching elements are cut off and experience a substantially equal voltage across the respective main terminals. In this way, the circuit may be usefully employed in integrated circuits which are based on a low-voltage integration process but which have also a high-voltage-supply rail (e.g. 30V). The switching elements may be bipolar transistors, and preferably Darlington pairs. <IMAGE>

Title: Ophtalmic lens with anti-toxin agent containing aliphatic polihydroxy-alcohol-fatty-acid-ester
Inventor: BROWN-SKROBOT SUSAN K
IPC: G02B1/14
Filed: 1994-03-02
Abstract: An ophthalmic lens for placement on the anterior surface of the eye is disclosed. The lens has impregnated in it or it has coated on its surface an ester of a polyhydric aliphatic alcohol and a fatty acid in which the alcohol residue has at least one hydroxyl group. The ester is present in an amount which is effective to prevent or decrease the release of bacterial toxins when the lens is exposed to those toxins. The lens is particularly well-suited for a soft hydrogel contact lens, and advantageously eliminates, minimizes or prevents keratitis. Bacterial keratitis is an infection of the cornea of the eye which may occur during extended wear of the lens and may cause ulceration of the cornea.

Patent IT-1212230-B (IT)
Title: Self closing container cover - uses pair of diaphragms carrying opening and valve stem
IPC: B65D/
Filed: 1977-07-08
Granted: 1989-11-22
Abstract: A pair of resilient discs or diaphragms are employed which in the closed position have their convex surfaces facing each other. One of these discs carries the valve opening and the other disc supports the valve stem which projects into and seats the opening in the closed position of the closure. Upon the application of opening pressure to the container contents, the resilient discs move axially of the closure and the convex surfaces change to concave surfaces. The valve stem is drawn away from the opening. The large axial movement of the discs is attained with minimal pressure yet secures a large opening area for dispensing the contents.

Title: Redn. of ferric to ferrous ions in acid ilmenite lixiviation soln. - by electrolysis in cell with liquid-impermeable anion exchange membrane
IPC: C01G/
Filed: 1979-01-11
Granted: 1987-05-05
Abstract: Redn. of Fe-III ions to Fe-II ions in a H2SO4-ilmenite lixiviation soln. (I) is effected by circulating (I) as catholyte through the cathode compartment of an electrolysis cell, sepd. from the anode compartment by a liquid-impermeable anion exchange membrane. A circulating FeSO4 soln. is used an anolyte. Electrolysis is carried out so that the Fe-III ions in the catholyte are reduced to Fe-II ions and pt. of the Fe-II ions in the anolyte are oxidised to Fe-III ions. Little energy is consumed and less FeSO4 waste accumulates, since the Fe can be recovered as metal in a second electrolysis stage. The Fe2(SO4) obtd. is useful in water treatment and in cultivation of land and lagoons.

Date Jun. 6, 1985.Digital signals which are sent each with their own frequency are corrected for frequency-dependent attenuation of the transmitting medium in a filter (5) so as to maintain a desired relationship between the amplitudes of the signals after the filter. Difference circuits (6) which have output signals (US1, US2, US3) control the filter means, obtain signals (Uf0) on their first inputs from a common voltage supply circuit (9) and signals (Uf1, Uf2, Uf3) on their second inputs from a voltage supply circuit (10) for each of the output signals. A decoder (18) sends a control signal (S0, S1, S2, S3) associated with the respective digital signal. The control signals reset switches (17) whereby the voltage supply circuits (9, 10) obtain signals from an amplitude detector (13) corresponding to the respective frequency in the transmitted signal. Each of the output signals (US1, US2, US3) fed to the filter (5) by the difference circuits (6 ) thus corresponds to a digital signal.

A primary group of elements regulate the direction of the material being extracted, moving it outside, towards the aforementioned frame. Another set of similar elements is set near the extension area of the aforementioned primary elements.

IPC: C23C/
Filed: 1976-01-28
Granted: 1981-10-10
Abstract: In applying a molten metal coating to a metal tube or other workpiece, the metal flows over the workpiece from a reservoir and a splash plate, pref. in the form of a tube, is provided to direct the flow around the workpiece. The splash tube is connectd to a reservoir to receive the molten galvanising material from slots or apertures in the reservoir. Molten metal is pumped from a heated kettle into the reservoir and molten metal flows from the bottom of the reservoir over the workpiece as it moves in a straight line beneath the reservoir. To make sure the coating has the required thickness the tube coated with molted metal is fed through a sizing die then exposed to an air knife. Used for galvanising steel tubes, partic. of small dia. Because of the relatively small space between the splash plate and the workpiece longitudinal flow is induced in the molten metal, and controlled in direction by shaping of the splash plate or by inclining the splash plate.

Title: Variable conformation ski
Inventor: TONEL VALERIO
IPC: A63C5/00
Filed: 1989-07-31
Granted: 1992-06-26
Abstract: The present invention concerns a mixed conformation ski. This is composed of a flat ski made of a layer of synthetic material in which is formed, in correspondence with the lower surface in contact with the bed of snow, a channel, while, in correspondence with the upper surface there is at least one longitudinal element. Said longitudinal element is in the zone of the attachments and at least one exterior edge of the ski itself. Advantageously, in addition to this, at least one element totally or partially corresponds with the longitudinal and/or transversal extension of the ski.
