Title: Means for extinguishing flames from fluid fuel burners in a drying apparatus
Inventor: HARRIS JOHN WILLIAM
IPC: F23C99/00
Filed: 1958-07-01
Abstract: 886,401. Controlling burners. TIMSONS Ltd. June 25, 1959 [July 1, 1958], No. 21020/58. Class 75(1) In an apparatus for drying thin flexible material such as paper, cloth, film or foil W by means of a gas burner comprising a manifold 2 fed with gas through a valve 6, the burner flame is extinguished when the gas valve 6 is closed, by combustion inhibiting gas e.g. pressure air introduced into the manifold 2 through a valve 13. The air blows out the flame. The gas valve 6 and the air valve 13 are electro-magnetically operated by two switches 8, 15 actuated by two cams 9, 16 on a shaft 10 driven by a speed control mechanism 5 associated with a motor (not shown) driving the paper W through the burner flames. Means may be provided to close the air valve 13 a fractional time after it opens so that only a shot of air is supplied to the burner manifold 2.

Title: A method of recovering substantially pure aromatics from hydrocarbon mixtures containing aromatics
IPC: C07C7/08
Filed: 1965-05-18
Abstract: Aromatics are separated from hydrocarbon mixtures by distilling in a first extractive distillation step operated in such a way as to obtain at least the lowest boiling aromatic in the overhead together with non-aromatics and higher boiling aromatics with solvent substantially free from non-aromatics in the bottoms, distilling said overhead to recover a second overhead containing the lowest boiling aromatic with non-aromatics and a bottoms containing higher boiling non-aromatics and subjecting said second overhead to a second extractive distillation to recover aromatics as bottoms with solvent. The two solvent bottoms may be stripped separately or together. In one embodiment benzene and toluene are taken overhead in the first extractive distillation and toluene is separated in the bottoms in the straight distillation.  This bottoms is also extractively distilled and the solution obtained used as solvent in the first extractive distillation or stripped together with the other solvent bottoms.  Specified solvents are N-methyl-pyrrolidone, sulpholane, polyglycols and ethylene or propylene carbonate any of which may have water added.

Title: Improvements in or relating to high-frequency cables
IPC: H01B11/20
Filed: 1956-07-06
Abstract: 810,679. Electric cables. SIEMENS & HALSKE A.G. July 6, 1956 [July 7, 1955], No. 21086/56. Drawings to Specification. Class 36. In a high-frequency cable having a plurality of unscreened balanced carrier-frequency transmission lines and a plurality of magnetically screened coaxial lines, at least some of which transmit mains-frequency currents along their inner conductors, distortion of the carrier signals due to the coaxial line mains-frequency currents is avoided by arranging that the coaxial line screens shall have substantially constant permeability with respect to magnetization resulting from the mains-frequency currents. Materials having linear magnetization curves over the modulation range, or which can be mechanically pre-treated to obtain this linearity, may be used. Additionally or alternatively the screens may be so arranged as to either operate at low flux densities or to saturate at low levels of induction by providing suitably disposed air gaps, e.g. by using slotted tubes, perforated or slotted iron tapes, or tapes wound on a coarse pitch helix with gaps between turns. Iron powder, either processed to shape or on insulating tape may be used, the iron particles being insulated from each other, and multi-layer screens with paper insulation between layers may be provided, only the outer or inner layer, or layers, being treated or arranged according to the foregoing.

IPC: G01K5/70
Filed: 1969-04-25
Abstract: 1,265,752. Thermometers. WESTON INSTRUMENTS Inc. April 25, 1969 [April 30, 1968], No. 21201/69. Heading G1D. A thermometer comprises a sealed housing 4, 20 supporting a temperature scale 31, a bi-metallic temperature sensitive element 6 coupled to a pointer 36 and oxygen getting material 14 which becomes active as the temperature nears the maximum temperature measurable by the thermometer. The material 14 is in the form of a thin tantalum ribbon and the element 6 comprises a pair of iron base alloy members, one member containing nickel and chromium whilst the other contains chromium. One end of the element 6 is welded to a plug 5 and the other end is welded to a shaft 9 which passes through guides 10-12. A ring 27 presses a transparent cover plate 25 against a gasket 26 to seal the housing 20. The scale 31, marked with the temperature range 200-1200‹ C. on its lower surface, is held in position by a ring 30 and a plane mirror 37 fixed to the housing 20 by lugs 38 enables the scale to be read. On assembly the thermometer is filled with an inert gas such as argon and heated to 1500‹ C. for a sufficient time to anneal the element 6. During this time the tantulum removes any oxygen in the housing to prevent the oxygen affecting the characteristics of the bi-metallic element. To assist calibration of the thermometer the scale may be rotated by rotating the ring 30, the ring then being locked by a screw 35. In a modification, the mirror 37 is dispensed with and the scale is mounted in the housing.

The grid members may alternatively be provided at one end with an apertured longitudinally extending tongue 36, Fig. 4, the apertures 37 of which may receive bendable tabs 35 on the relatively opposite end of an identical adjacent member when the grid members are required to be connected end-to-end to form a transverse member having a ventilation passage as an alternative to the member 12 shown in Fig. 1. Grid members according to the invention are provided with aligned pairs of apertures 27 through the spaced apart webs 13, 13'.

Title: A process and apparatus for de-scaling metals
IPC: B08B3/12
Filed: 1954-07-21
Abstract: Metals to be de-scaled are first treated in a pickling bath and then subjected to sonic or ultrasonic oscillations in a second bath, e.g. a water bath, the oscillations being caused to operate on the metals with such high energy that cavitation takes place. Preferably, a plurality of sound emitters are used and arranged in staggered relationship so that the metal to be de-scaled may be guided between said emitters and thus subjected to oscillations alternately from at least two sides.  A pickling bath of 10 per cent H2SO4 is referred to.

Abstract: 853,952. Variable attenuators and phase shifters. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 8, 1957 [July 11, 1956], No. 21542/57. Class 40(8). A waveguide impedance matching device comprises a first flat resistive strip secured along the waveguide axis, and a terminating plunger, which supports a second resistive strip perpendicular to its surface, and is rotatable and axially movable so that the modulus and argument of the reflection factor are independently adjustable. In a circular-waveguide G, a horizontal strip S1 of mica coated with carbon is symmetrically positioned axially of the guide. A terminating plunger Z is arranged in three sections Z1, Z2 and Z3 and on its terminating surface C carries a second mica strip S2 coated with carbon. The vertically polarized input E (not shown) from B passes the horizontal plate Sl, and if the plate S2 is at an angle a (not shown) to the vertical the component E sin a only is reflected at C and only component E sin<SP>2</SP> a passes plate Sl and provides the reflected wave. The argument of the reflection factor, i.e. the phase difference between E and E sin<SP>2</SP> a is adjustable by axial movement of the piston and the strength of the reflected wave E sin<SP>2</SP> a is adjustable by rotating the plunger and plate S2. The device may be employed in "magic-T" junctions for calibrating unknown impedances.
