Patent EP-0117640-A2 (EP)
Inventor: BREDA SILVANO
IPC: E03C1/10
Filed: 1984-01-27
Abstract: A diverter valve is provided with an integral backflow preventer in the form of a vacuum breaker. In one embodiment, a diverter valve, for example for a bath, comprises a body (38) having a lower opening (40) for connection to a water supply and two outlet openings (42,44). A tube (70) fits into the body (38) and is rotatable to allow a lateral opening (72) in the tube to be selectively aligned with one or other of the outlets (42,44). Water supplied through the inlet (40) flows through an inner tube (66) to a chamber (48) defined between the two tubes (66, 70) and thence through opening (72) in the outer tube (70). When the water supply is cut off, a float valve (106) closes the top of the innertube (66) and the chamber (48) is in communication with the atmosphere through an air port (103) in a cap (80) fixed to the top of the outer tube (70). When water flows through the inlet (40) the valve (106) is raised to open the inner tube (66) and to close the air port (103). An alternative embodiment for use in a bidet is described, and other applications of the valve are mentioned.

Abstract: A method of contransforming appropriate host cells with at least two distinct DNA sequences whose products ineract with each other after production in the host cell. Mouse cell lines engineered by that method to produce at their surface human Class II antigens of the major histocompatibility complex. The mouse cell lines of this invention are cotransformed with at least a DNA sequence encoding the a-chain of the selected human Class II antigen, a DNA sequence encoding the β-chain of that antigen and a DNA sequence encoding a selectable marker. More preferably, the mouse cells are also cotransformed with a DNA sequence encoding the In chain of that antigen. These mouse cells are useful in producing those antigens and in forming hybridomas that are characterized by monoclonal antibodies recognizing allospecific determinants of those antigens. These antibodies are useful in typing and therapeutic processes and compositions.

Abstract: @ During unrodded refueling, the drive rods and the control rods and coolant-displacement rods, attached to the drive rods, are removed from a fuel assembly, preliminary to the transfer of the fuel assembly, and are reinserted in the reactor after a replacement fuel assembly has been positioned in the reactor. Prior to the transfer of a fuel assembly, a lifting rig is secured to the upper-internals support. A lift plate is removably mounted on latches in a lower position of the lifting rig. The latches are released and the lift plate is connected to the drive rods. The lift plate is then raised and removably mounted on latches in an upper position on the lifting rig. In this position, the control rods and coolant-displacement rods are in the guides in the upper internals of the reactor. During the lift-plate raising operation, the loading on the drive rods is monitored and if the loading exceeds a predetermined magnitude, the excess loading is indicated. After the lift plate and the rods suspended from it are positioned on the latches in the upper position, the lifting rig and the upper internals and rods attached to the lift plate are removed from the reactor so that the unrodded transfer of the fuel assemblies may proceed. The replacement of the rods proceeds reversely. In this case, the device which indicates excess loading of a drive rod operates to indicate that the control rod or coolant-displacement rod connected to the drive rod has encountered an obstruction.

Abstract: An electronic device for measuring blood pressure, according to which either systolic pressure may be derived from mean pressure and diastolic pressure, or diastolic pressure may be derived from systolic pressure and mean pressure, whereby the time duration of the application of pressure to the patient's arm may be reduced because the pressure to be applied may only range substantially over between mean pressure and diastolic pressure or between systolic pressure and mean pressure. Additionally proposed is a means for improving the accuracy of the above- mentioned derivation of systolic pressure or diastolic pressure. As a result, considerable reduction in the time duration required for measurement may be reduced without any increase in measurement errors.

Abstract: A method of manufacturing a semiconductor device comprising the steps of forming source and drain regions (40, 42) in a semiconductor substrate (10) in a spaced-apart relation, forming a floating gate (26) such that it overlies a channel region between the source and drain regions with a gate insulating film (16) formed between the floating gate and the channel region and forming a control gate (38) such that it overlies a floating gate (26) with an insulating film formed between the control gate and the floating gate. An oxidation-resistant film pattern (22) is formed over a non-monocrystalline silicon layer (18) so as to have a predetermined opening (20). With the oxidation-resistant film pattern (22) as a mask, the non-monocrystalline silicon layer with the opening is selectively oxidized to form a separation insulating film (24) whereby a floating gate is formed with a part of the non-monocrystalline silicon layer insulatingly separated and a floating gate layer portion (28) adjacent to the separation insulating film is smoothly formed.

Abstract: The method of manufacturing a slide fastener with a separable end stop according to the invention includes: a step which is carried out while separating engaged stringers of continuous length which have space portions disposed at regular intervals in their longitudinal directions and which consists of conveying the separated stringers through an injection molding station; suspending the operation of conveying the stringers in such a manner that one of the space portions is disposed at the injection molding station; and simultaneously injection-molding upper stops and pins which constitute a separable end stop on the stringers at each end of the space portion. The improvement comprises a step, carried out prior to the injection molding step, of independently bending a portion of the tape which constitutes each of the stringers at the space portion within the injection molding station, whereby the respective portions of the stringers on both sides of the space portion are moved toward the center of the injection molding station and whereby end fastener elements at opposite ends of the space portion are respectively retained by stoppers which are made immovable relative to the injection molding station in terms of the moving direction of the stringers, thereby effecting positioning of the stringers. Also disclosed is an apparatus which can be suitably employed to carry out the above-described method.
