Title: Improvements in turbine speed limiting arrangement
Inventor: ALLEN ELY GEORGE
IPC: F01D21/02
Filed: 1959-05-05
Abstract: 881,850. Machinery breaking pieces. GENERAL ELECTRIC CO. May 5, 1959, No. 15351/59. Class 80 (4). [Also in Group XXVI] In a speed limiting arrangement for a turbine rotor having blades extending radially from a hub and so designed that, on attainment of a predetermined high rotational speed, portions of the blade are broken away by centrifugal force, the aerofoil portion of each blade is provided with a stress failure section near the hub so that the,aerofoil portions located radially outwardly of the stress failure section are thrown outwardly before failure occurs in any other part of the rotor, the remaining blade portion having insufficient area to produce a continued acceleration. A hole 28 is drilled near the base of the aerofoil portion 26 of each rotor blade of an air turbine to weaken the blade, the axis of the hole preferable intersecting the radial line extending through the centre of mass of the aerofoil to minimize the effects of the removal of material on blade bending moments and vibration characteristics. In the event of failure of both the normal control and the overspeed control of the air supply to the turbine, a speed is reached at which the blades rupture at the vicinity of the holes 28, so that the parts of the blades beyond this region are thrown from the rotor. The remaining stumps of the blades are sufficiently small to ensure that the speed cannot rise further to produce a catastrophic failure of the rotor. An annular reinforcement 29 prevents the blade fragments from bursting through the turbine casing.

Title: Manufacture of multiconductor electric cables and apparatus for use therein
IPC: G01R31/02
Filed: 1948-06-10
Abstract: 657,313. Detecting faults. WESTERN ELECTRIC CO., Inc. June 10, 1948, No. 15693. Convention date, June 11, 1947. [Class 37] To detect breaks or short-circuits in a pair of twisted insulated wires 11, 12, Fig. 1, the insulation 10 containing moisture, a direct current from G is applied between the two wires for a time sufficient to produce electrolytic polarisation of the insulating material, and after being disconnected the residual polarisation is measured by connecting a voltmeter V. An ammeter A indicates if the wires 11, 12 are in connection, while a reading of e.g. 1¢ volts on V indicates that the wires are intact and that the insulation will be satisfactory when dry ; a lower voltage reading on V will indicate either a break or a short-circuit. If any appreciable current flows from the generator G, a relay opens contacts 21. In a modification, the voltmeter V is replaced by two voltmeters V, Fig. 2, which can be connected across each wire, the switch 16 is adapted to connect the two wires together. In operation, switch 14 is closed, a large deflection on voltmeter 18 indicating a short-circuit; if there is no shortcircuit, switch 14 is opened after e.g. 30 minutes and switches 19, 20 closed; a break in one wire is stated to produce a higher reading in the voltmeter 117 or 217 connected across it; if both voltmeters read high, e.g. 0.5 volts, both wires are stated to be broken; if both voltmeters read low, e.g. 0.2 volts, switch 16 is closed, and no detectable change in readings stated to indicate a short circuit.
Patent GB-698291-A (GB)
Title: Method of preparing -a,-a-dialkylaryl carbinols
Filed: 1951-07-02
Abstract: A process of preparing an alcohol of the formula ROH comprises contacting a hydroperoxide of the formula ROOH with an arylsubstituted hydrocarbon of the formula RH in the presence of a heavy metal salt catalyst out of contact with sufficient air to cause oxidation thereof until substantially all the hydroperoxide has reacted, R in each instance being similar or dissimilar radicals of the formula <FORM:0698291/IV (b)/1> where R1 and R2 represent alkyl groups and Ar represents an aryl or substituted aryl radical.  The radical Ar may be an alkylated phenyl, a chlorophenyl a nitrophenyl group or a tolyl group.  The catalysts are organic or inorganic salts of heavy metals, i.e. metals of density greater than four and atomic weight greater than forty, e.g. lead, manganese, iron, zinc and cobalt.  Preferred salts are the resinates, naphthenates, stearates, oleates, cumates and laurates.  The process is usually performed by oxidizing the aryl-dialkylmethane with an oxidizing gas in the absence of heavy metal salts until part of it is oxidized to the corresponding hydroperoxide, and then mixing the hydroperoxide with the hydrocarbon to give a solution containing less than about 30 per cent hydroperoxide in the presence of the heavy metal salt catalyst. The hydroperoxide is preferably added to the mixture at the same rate as it reacts.  The amount of catalyst should be within the range 0.4 to about 20 per cent of the weight of the reaction mixture, and the temperature from 40 DEG  to 70 DEG  C.  In examples: (1) a ,a -dimethylbenzyl hydroperoxide in cumene is added to cobalt naphthenate in cumene in a nitrogen atmosphere, and the catalyst filtered and the product distilled to give a ,a -dimethylbenzyl alcohol.  (2) A dispersion of p-diisopropylbenzene in 2 per cent aqueous sodium hydroxide containing dispersed potassium stearate is contacted with oxygen until the organic layer contained 30 per cent hydroperoxide and 70 per cent p-diisopropylbenzene.  This was then added dropwise to a solution of dehydrated lead-manganese acetate in diisopropylbenzene and the catalyst filtered off and the product distilled to give a ,a -dimethyl-p-isopropylbenzyl alcohol; (3) a mixture of p-cymene and a ,a  - dimethyl - p - methylbenzyl hydroperoxide is dropped into a solution of manganese naphthenate in cymene.  The catalyst was filtered and the product distilled to give a ,a -dimethyl-p-methylbenzyl alcohol.

Title: System for the transmission of electric waves along a dielectric guide
IPC: H04B3/52
Filed: 1933-06-02
Abstract: 420,447. Wired wireless systems. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London.- (Western Electric Co. ; Inc., 195, Broadway, New York, U.S.A.) June 2, 1933, No. 16002. [Class 40 (v)] A carrier-frequency of the order of 1750 megacycles, modulated by signal frequencies extending over a band of 2 megacycles, is transmitted through a " dielectric guide " 11, Fig. 1, which may, for instance, consist of a conduit 6À6 cm. in diameter containing liquid chlor-diphenyl, and extending for five miles in length. Alternatively the " guide " may consist of a core and concentric shells of the same or different dielectrics, such as paraffin wax alone or mixed with mica, rubber with or without zinc oxide, &c. ; also it may have an outer conductive shell and an inner conductive core. The modulated signal energy from the valve 3 is applied to the " guide " across an annular-ring electrode 10 and a central disc electrode 9, and is taken off from annular electrodes 13, 14 at the receiving end and passed through a rectifier 15 and amplifier 17. Fig. 2 shows a modified form of the terminal electrodes 9, 10 to facilitate impedance matching. As shown in Fig. 3, the valvegenerator 35 is housed in a metallic covering 33, which is mechanically attached to the " guide " 30. The valve makes direct contact with the terminal electrodes through its grid 36 and the anode 38. At the receiving end of the "guide", a section 68, Fig. 7 of carborundum or zinc oxide mixed with clay, or other suitable rectifying material may be used as a demodulator or frequency-changer. In a suppressed carrier system, Fig. 8, the " guide " 70 is coupled at 71 to a detector 72, whilst a local oscillator 73 supplies carrier-frequency through a dielectric "guide" 74 having an adjustable iris coupling 75 to regulate the energy level. For two-stage reception a second detector 77 and oscillator 78 are added as shown in Fig. 9. Polarization of the displacement waves " through the "guide" may be effected by suitably orientating the terminal electrodes and the phase of the applied currents. Multiplexing may be effected by separately modulating the carrier wave supplied to each pair of electrodes (Fig. 6 not shown). A filtering effect may be secured by making an abrupt change in the diameter of the guide.
