Filed: 1926-10-15
Abstract: 260,972. Metropolitan-Vickers Electrical Co., Ltd.., (Assignees of Allen, R. C.). Nov. 4, 1925, [Convention date]. Mounting and supporting.-One portion of a turbine casing is constrained so that it cannot move relatively to the foundation, remaining portions of the casing being supported on curved bearing surfaces so as to move readily upon expansion or contraction. A dowel pin 22 engaging a recess 14 in the sole plate 10 holds one end of a turbine casing in a fixed position, and maintains the longitudinal axis central at that end. At the other end of the sole plate a key 16 engages a slot in the turbine casing, allowing free longitudinal movement but maintaining the longitudinal axis central. The casing is supported at the corners on members 11 having spherical bearing surfaces allowing free expansion away from the dowel 22. For supporting a double-flow turbine, the dowel pin may be located in the centre of the sole plate, and the supports 11 extend upwards as far as the level of the turbine axis. In a modification, Figs. 8 and 9, one end of the turbine is anchored by a pin 43 held by a plate 42 bolted to the sole plate, while the other end is constrained to move in a small arc by a pin 48 carried by a pivoted link 47.

Title: Improvements in or relating to electric band-stop filters
Inventor: ROSEWAY WALTER NORMAN
IPC: H03H9/54
Filed: 1955-09-14
Abstract: 772,217. Bandstop filters. STANDARD TELEPHONES & CABLES, Ltd. Sept. 14, 1955, No. 26272/55. Class 40 (8). A bandstop filter having an extremely narrow stop-band comprises a bandpass filter section 5, Fig. 1, and a bandstop filter section 6 connected in parallel to produce a network having no significant attenuation at any frequency, a sharply resonant electromechanical device being connected in the bandpass filter section 5 in such a manner as to introduce a narrow stop-band into its attenuation characteristic. The bandpass and bandpass filters are conventional T- networks and have attenuation characteristics 24, 25, Fig. 5. A piezo-electric crystal 27, Fig. 7, preferably having a resonant frequency (not shown on Fig. 5) coinciding with one of the peak attenuation frequencies P1, P2 of the bandstop filter 6, is incorporated in the shunt arm of the bandpass filter 5 (shown in detail in Fig. 7), the shunt capacity of the crystal being compensated by adjustment of the value of the shunt capacitor C6. The sharpness of the attenuation peak introduced by the crystal depends upon the impedance presented by the bandpass filter to the crystal and this impedance may be increased by inserting on either side of the shunt arm impedance-transforming networks theoretically consisting of three capacitors C9, C10, C11, Fig. 10, whose values are given in terms of the series capacitor C1, Fig. 7, and the chosen transformation ratio 1: k<SP>2</SP>. The impedances of the elements L2, L6 in the shunt arm are then multiplied by k<SP>2</SP>. Since k is positive C11 is negative and is obtained by appropriate reduction of the value of the shunt capacitor to give the capacitor C12 of Fig. 11. The modified circuit is completed by the addition of the piezo-electric crystal (not shown in Fig. 11) in parallel with C12, the shunt capacity of the crystal being compensated as before by adjustment of C12. The maximum value of k obtainable is that for which the adjusted value of C12 is reduced to zero. In order to reduce the value of k the crystal may be replaced by a number of crystals in parallel, such an arrangement having a lower impedance than a single crystal. When the crystal has unwanted resonances which lie within the chosen band-width of the bandstop filter 6 it is replaced by two crystals 42, 43, Fig. 14, in series, each having half the impedance of the crystal 27 and a principal resonance at the same frequency. Unwanted resonances occur in general at different frequencies within the band-width. If each crystal is shunted by a resistor 44 or 45 equal to the impedance of its shunt capacity at resonance it can be shown that the impedance of the two crystals together will not fall below half the image impedance of the filter at the unwanted frequencies. Hence no attenuation peaks occur within the chosen band-width. The piezoelectric crystal may be replaced by a magnetostrictive or electromagnetic resonator.

Title: Improvements in or relating to composite electric conductors
IPC: B29C48/05
Filed: 1927-10-06
Abstract: 303,561. Beatty. W. E., (Bell Telephone Laboratories. Inc.). Oct. 6. 1927. Drawings to Specification. Loaded cables; processes for making.-Relates to the construction of a loaded signalling cable in which a tape of magnetic material, preferably an alloy of nickel or iron, is wound on a copper core. The wound core is heat-treated to develop its desirable properties, but. it is found that the tape adheres to the core with resulting undesirable effects. According to the invention, the adhesion is prevented by applying a thin layer of a metal, such as nickel or other metal having its melting point well above the annealing temperature of the magnetic material, to the surface of the copper conductor prior to the application of the magnetic wrapping. The separating metal is preferably applied to the copper conductor by spraying with a Schoop's pistol, but it may be applied by other means. The magnetic tape is wound on to the coated core and the composite conductor is heat-treated. The same method may be applied to a stranded cable by spraying the metal on to the flat surface of a copper strip which is afterwards wound on to a copper core with the sprayed surface outwards. The magnetic tape is applied over the coated strands.

Title: A process for transforming hydrocarbon oils into other hydrocarbons having a lesser number of carbon atoms in the molecule
IPC: B01J23/24
Filed: 1945-10-11
Abstract: Hydrocarbon oils, for example crude oils, low temperature tar oils, and shale oils, are converted into aromatic hydrocarbons and gas rich in ethylene by contacting them in vapour state, substantially unmixed with free oxygen, with a mixture of at least two of the following three oxides, viz: molybdic, chromic, and ferric oxides, activated with vanadium pentoxide, at about 800-1100 DEG  F. to dehydrogenate the hydrocarbons, the unsaturated aliphatic hydrocarbons in the product then being hydrogenated to yield olefins and paraffins. Preferably equal weights of the three oxides are used, but variations up to 10 per cent more or less of each are permissible.  Vanadium pentoxide is equivalent to about 2-10 per cent of the weight of the other oxides.  The hydrogenation is effected by passing the products with steam over a mixture of 90-98 per cent iron and 2-10 per cent copper in finely-divided form at about 1000-1400 DEG  F.  Suitable apparatus comprising a converter with lower and upper sets of tubes for the two stages is described in U.S.A.  Specification 1,752,692. The hydrocarbons are passed in vapour or liquid phase into the lower tubes containing the oxide mixture yielding about 80 per cent aromatic hydrocarbons, and the remainder unsaturated aliphatics. Superheated steam is injected with the products into the upper tubes containing the metals.  The products may be quenched with oil or water, fractionated, and the overhead condensed to give a motor fuel containing benzene, toluene, and xylene, and a gas which is about 40-45 per cent ethylene.
