Patent GB-1454491-A (GB)
IPC: G21C17/017
Filed: 1964-12-16
Abstract: 1454491 Inspecting for leaks and defects FOSTER WHEELER Ltd 4 March 1966 [16 Dec 1964] 51212/64 Heading G1S [Also in Division F2] A testing and/or repairing tool for use within the headers of heat exchangers, the heat exchange surface of which comprises tubes that have their ends fixed in tube holes in the longitudinal walls of one or more elongated headers extending perpendicularly to the tubes, comprises a working tool head carrying a testing and/or repairing device and being pivotally mounted on a boom so as to be capable of being swung in line with the boom during its insertion through an access hold in the end of a header by control means operable from outside the header, manipulating means extending along the boom for bringing the testing and/or repairing device into working relationship with a tube hole in the header longitudinal wall and which are also operable from outside the header. Such a tool has the advantage of only requiring relatively small holes in the header and also the surrounding shell, when present, with the result that the header and the shell do not have to be made much stronger in the regions of these holes. In the case of heat exchangers used in nuclear installations, the tool operator can be positioned away from the header and be shielded at least to some extent from any radio-activity. The tool may include an introscope arranged to view in the region of the tool head so that the operator can look for leaks and watch the operation of the tool head. The tool head is movable both along and around the header so that it can be brought to work on the end of any of the tubes connected to the header. It is also movable radially of the boom towards and away from the end of a tube. It may have mounted on it a number of devices to effect different operations on a tube. Thus, initially a locating plug may be fitted to the head for setting up the tool for a particular leaking tube. Next a reaming tool may be fitted to form a good seating for a plug. Finally a pneumatic hammer may be fitted to drive a plug  into the tube by repeated blows. The boom member has a support at one end which is fixed to the outside of the header or shell and a locating boss at the other end which is inserted into a corresponding hole in the end of the header opposite that through which the tool is inserted. Defective tubes can be located by pressurizing a liquid such as water within the shell and watching for drops to appear at the holes in the header. Alternatively, the shell can be pressurized with argon or other gas or vapour and the working head fitted with a suitable detector probe. Weld defects can be located by means of an ultrasonic probe.

Abstract: 1,245,714. Plate vibrators. STANDARD TELEPHONES & CABLES Ltd. 30 Oct., 1969, No. 53192/69. Heading G5J. [Also in Divisions H1 and H3-H5] A tone generator, e.g. for use in a telephone dialling system, comprises an electrically sustained vibratory reed 3 formed in part out of or mounted on a leaf spring 1, the vibration of the reed being normally suppressed by a damper 10 held in contact with the reed but excited when the leaf spring is snapped from one bowed state to another to remove the reed from the damper. In Fig. 2a, the leaf spring is snapped over by means of a push-button 9 acting on the spring via a resilient linkage 11; a return spring 8 acts in the opposite direction. In Fig. 3, integral portions 12, 13 and 14, 15 of the leaf spring perform respectively the functions of a return spring and a resilient linkage. A five-layer piezo-electric element, of which the vibratory reed tongue constitutes the central layer, has inner layers adjacent the reed tongue comprising lead zirconate titanate bonded to the tongue and outer metal layers forming the electrodes. Alternatively, in a seven-layer structure a metal-piezo-electric ceramic-metal sandwich may be bunded to each side of the reed tongue. The outer electrode layers are of graded composition varying from a Ni-Cr alloy to gold with the alloy adjacent the ceramic to enable the making of soldered connections. The transistor oscillator circuit by which the vibration of the reed is sustained comprises a two-transistor amplifier network, Fig. 4 (not shown), with integrating circuits (R1, C1 and R2, C2) ensuring adequate phase-shift in the feedback loop and also serving to suppress overtone frequencies. An additional emitterfollower stage may be included, Fig. 5 (not shown). A telephone dialling system may include two assemblies of tone generators, each assembly corresponding to a high frequency or a low frequency band having four reeds, the reeds in each assembly being connected in parallel in a common amplifier circuit.

Simple carbonitrides and oxycarbonitrides of Group VA transition metals, and solid solutions of carbonitrides or oxycarbonitrides of a Group VA metal and at least one of a Group IV A , VA or VI A  metal, or a Group IV A  and VIA metal are prepared by heating an appropriate nitride, oxynitride or solid solutions thereof at a temperature of from 800‹ to 1000‹ C. in an atmosphere containing a hydrocarbon, e.g. methane, hydrogen to prevent the cracking of the hydrocarbon and, where necessary to prevent complete carbidation, a free nitrogen providing gas e.g. nitrogen itself or ammonia. The composition of the product may be controlled by the temperature or the proportion of nitrogen in the atmosphere. The starting nitride or oxynitride may be prepared by the reaction of ammonia or nitrogen at 700‹ to 1000‹ C. with a hydrated or calcined oxide, an organic or mineral salt of the transition metal to obtain the simple oxynitride or with a coprecipitate of hydrated oxides or mixed crystalline complex of the transition metals to obtain a mixed nitride or oxynitride.
