Abstract: A surgical instrument, in particular for percutaneous disectomy, includes a hollow elongate blunt needle (16) having a port (48) in its wall adjacent its tip (46). A hollow tubular cutting member (42) is situated within the needle and has an outwardly flared cutting edge (44). The interior of the cutting member (42) is connected, in use, to a source of suction and it is positioned within the needle such that the cutting edge contacts the internal surface of the needle. The interior of the needle communicates with the interior of the cutting member adjacent the port (48). The wall of the cutting member (42) is spaced from the wall of the needle (16). In use, the annular space defined between the needle (16) and the cutting member is slid longitudinally to sever tissue which is sucked in through the port (48), which tissue is then removed through the interior of the cutting member by suction and/or irrigating fluid.

Abstract: 57 A method of making a hearing aid begins with an impression of the ear concha (4) and canal (6). A wax coating is applied over the surface of the impression to fill in depressions created by skin pores, A base plate (10) is shaped to the bottom portion of the mould. A top portion (12) of the mould is then formed over the remainder of the ear impression. The mould is then cut open to remove the original ear cast. 
     After resealing of this opening, a top opening Is cut. This opening is preferably formed by cutting off the extended portion (6a) impression of the ear canal, The mould is filled with a hardenable acrylic material until it is full: the hardening of the material is carefully timed so that only the mould has permanentaly formed. The remainder of the acrylic hardening material is then poured out, and the ear hearing aid is removed.

Abstract: A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample and a first member of a specific binding pair with an end portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The first member of a specific binding pair is capable of binding the analyte. The strip contains a second member of a specific binding pair integral therewith for concentrating and non-diffusively binding the first sbp member at a small situs on the strip separated from the end portion of the strip. The detectible signal is produced in relation to the presence of the analyte in the test solution. The test solution passes through the situs as the test solution traverses the bibulous material. After the test solution has been allowed to traverse at least a portion of the strip, the strip is contacted with a developer solution containing members of a signal producing system in a manner that provides contact of the developer solution with the small situs following its contact with the test solution. The strip is then contacted with any remaining members of the signal producing system. The detectible signal produced at the situs is then compared with the signal detectible at a portion of the strip other than the situs to determine the analyte in the sample. In one embodiment of the invention the signal produced at the small situs has a sharp-edged distinctive pattern that provides a sharp contrast to the signal produced at adjacent sites on the strip when analyte is present in the test solution.

Abstract: A coating is formed on a substrate by sputter ion plating wherein a DC glow discharge is generated under soft vacuum conditions in the presence of the substrate and of a cathode constituted by the coating material thereby to release material at the cathode by ion bombardment, which released material diffuses to the substrate to form the coating thereon, and wherein a potential is applied to the substrate during coating. 
     The coating material comprises a MCrAlSi allow (where M is a single metal or combination of metals selected from the group consisting of nickel, cobalt and iron) and the potential is in the form of an AC bias in order to control the properties of the coating. It is thereby possible to coat uniformly subtrates having sharp edges such as aerofoil components. Moreover, the coatings are found to possess outstanding corrosion resistance properties.

Abstract: A user connected by telephone to a central telephone exchange can inform an automatic switching communications device directly of his own telephone number by dialing on his telephone set, which determines the corresponding address and all other possible characteristics from an on-line directory. The available taxis are entered in a stand-by memory. The taxis in first place in the stand-by memory is provided with the assigned address by the switching communications device via radio. The total area serviced by the device for the switching communications exchange of the taxis, can be partitioned into individual sectors, whereby each sector then corresponds to its own stand-by memory. Therefore, a very quick and efficient switching communications exchange is possible without a large expenditure for personnel.
