Title: Apparatus for analysing signals comprising excursions from a nominally constant background level
Inventor: GUBISCH ROLAND WERNER
IPC: G01N30/86
Filed: 1967-07-31
Abstract: 1,214,153. Selective signalling. NATIONAL RESEARCH DEVELOPMENT CORP. 31 July, 1968 [31 July, 1967], No. 35130/67. Heading G4H. [Also in Division G1] In a circuit for obtaining a signal free of baseline drift from a signal V, Fig. 3 (e.g. from a chromatogram), having base-line drift, the signal V is differentiated and when the derivative V 1  exceeds a pre-set threshold level found by experiment to be just larger the maximum rate of base-line drift, a signal V 3  is produced which causes the input signal V to be inverted and clamped, V 4 , at its value at that instant, which clamped signal V 4  is added to the input signal V to produce a signal V 5  substantially free of base-line drift. As described, the derivative signal V 1 , produced by a circuit 21, Fig. 2, is rectified, 22, before being applied to a threshold circuit 23 set just higher than the maximum rate of base-line drift, and the output signal V 3  is used to control a circuit which inverts and clamps the input signal V, the output of which, V 4 , is added, 25, to the input signal V to produce the required signal V 5 . The trough in the rectified signal V 2  identifies the peak of the input signal and is particularly useful when two adjacent peaks occur without an intermediate return to the base-line. So that such overlapping peaks may be detected, the output signal V 5  is applied to a threshold circuit 26 the output V 6  from which only falls to a low level when the signal V 5  falls below a threshold level, and this signal V 6  is also applied to the threshold circuit 23 so that its output, having gone high because the derivative signal V 1  has exceeded the maximum rate of base-line drift, remains high until the signal V 5  falls to below its threshold. In a modification (Fig. 5, not shown) a second derivative is used in place of the first derivative. The Specification also outlines a system for digitizing any peaks in the output signal V 5 , using the rectified signal V 2  to identify them, and for integrating the signal V 5  for the duration of signal V 3  to find the area under each peak or multiple peak.

Title: Fluorine-containing silanes and their hydrolysis products
IPC: C07F7/08
Filed: 1954-12-06
Abstract: 760,201. Fluorine-containing silanes and siloxanes. MIDLAND SILICONES, Ltd., [formerly DOW CORNING, Ltd.]. Dec. 6, 1954 [Dec. 21, 1953], No. 35307/54. Class 2 (7). Silanes and mixtures thereof of the general formula: wherein R is a monovalent hydrocarbon radical free from aliphatic unsaturation, one of the X's is fluorine, the other is chlorine or fluorine, Y is a halogen, and n has an average value of 0 to 2 are best prepared by heating vinyl silanes of the formula: with tetrafluoroethylene and/or trifluorochloroethylene under pressure at a temperature of at least 125‹ C. The use of trifluorochloroethylene results in the production of two isomers, the chlorine atom being on the carbon atom two or three removed from the silicon. Suitable vinyl silanes are vinyl tribromo-, vinyl methyl dichloro-, vinyl dimethyl chloro-, vinyl octadecyl dichloro-, vinyl phenyl dibromo-, vinyl benzyl difluoro-, vinyl xenyl dichloro- and vinyl phenyl methyl chloro-silane. Siloxanes are prepared by hydrolysis of the above silanes, using, if desired, a solvent such as benzene, toluene or ether. They may be copolymerized with other siloxanes of the general formula: where R<SP>1</SP> is a non-hydrolysable organic radical and m has an average value of 1 to 3, e.g. by cohydrolysing the corresponding silanes or by catalytic copolymerization of the siloxanes, preferably using acid catalysts. The siloxanes or their copolymers may be obtained in the form of liquids, resins or elastomers by varying the ratio of organic radicals on the silicon atom from 3 to 1. In the examples : (1) Chlorotrifluoroethylene and vinyl methyl dichlorosilane are heated to produce the isomeric (2) The isomeric phenyl derivatives were similarly prepared using phenyl vinyl dichlorosilane. Hydrolysis yielded a viscous liquid polysiloxane having the unit formula: (3) The mixed silanes of Example (1) are also hydrolysed to a viscous liquid polysiloxane. (4) Liquid copolymers are obtained by hydrolysing 45 mol. per cent of dimethyl dichlorosilane, 10 mol. per cent of trimethyl chlorosilane and 45 mol. per cent of the silane of Example (1). Similarly, when 90 mol. per cent of the latter silane is hydrolysed with 10 mol. per cent of trimethyl chlorosilane. (5) A viscous high polymer containing Me 2 Si0 units (90 mol. per cent) and (F 3 ClC 4 H 3 ) MeSiO units (10 mol. per cent) is milled with fumed silica, ferric oxide and tert. butyl perbenzoate and the rubber is vulcanized. (6) The silanes of Example (1) are cohydrolysed with dimethyl- and vinyl methyl dichloro-silanes and the product is compounded into a rubber as in (5). (7) The isomeric silanes: are obtained from chlorotrifluoroethylene and vinyl tribromosilane and are hydrolysed to the siloxane. (8) Tetrafluoroethylene is reacted with vinyl methyl dichlorosilane to give: and the siloxane is prepared by hydrolysis. (9) Vinyl dimethyl fluorosilane is reacted with tetrafluoroethylene giving: and this is hydrolysed to give the disoloxane.

Title: Improvements in or relating to circuit arrangements for production of ultrasonic oscillations
IPC: H02M7/44
Filed: 1963-09-09
Abstract: 1,026,085. Valve oscillating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 9, 1963 [Sept. 12, 1962], No. 35475/63. Heading H3F. [Also in Division G4] The invention relates to a circuit for driving an ultrasonic electromechanical transducer 8, Fig. 1, as shown, comprising a push-pull oscillator 1, 2, in which oscillation is maintained by feedback from the transducer and the frequency of oscillation is determined by the mechanical resonance of the transducer. In such an arrangement the tendency is for the frequency of oscillation to change as the loading on the transducer is varied; in accordance with the invention this is prevented by arranging the output of the oscillator as a bridge circuit whose arms comprise resistors 20, 22, the natural inductance of the energizing winding 6 of the transducer, and a corresponding inductor 21. The feed-back is taken via lead 11 from the common point of resistor 22 and inductor 21. The bridge is arranged to be balanced at frequencies other than that of mechanical resonance of the transducer; to reduce loss to a minimum resistor 20 is made appreciably smaller, and the combination of resistor 22 and inductor 21 considerably greater, than the impedance of the transducer 8. The output transformer 5 is tuned to the resonance frequency of the transducer by means of a capacitor 25 shunting the secondary winding, and the input transformer 12 may be similarly tuned. The transducer 8 comprises a pair of U-shaped members 9, 91 of low-loss piezo-magnetic material, e.g. ferroxcube with interposed bias magnetization plates 10, 10<SP>1</SP> of permanent magnetic material, e.g. ferroxdur. In a modification (Fig. 4, not shown), the inductor 21 is replaced by a resistor and the resistor 22 by a capacitor. The arrangement may also be used for driving a piezo-electric transducer (Fig. 5, not shown), in which case resistor 22 is retained but inductor 21 replaced by a capacitor. In a further modification the output transformer 38 (Fig. 6, not shown), is provided with a tapped secondary winding, the two parts 36, 37 of which form two arms of the bridge; the other arms comprise the inductance of the transducer winding 6 and an inductor 35, feedback being taken across resistor 41 forming the diagonal of the bridge. The preceding circuits have been on the basis that the transducer appears in the circuit as having a series electrical resonance (Fig. 2, not shown); the Specification also describes a modified circuit (Figs. 7, 8, not shown), which is applicable in the case that the transducer appears as a circuit having a parallel electrical resonance.

Title: Improvements in or relating to devices for removing solid matter from smoke
IPC: B01D46/10
Filed: 1953-12-24
Abstract: 759,936. Chimney smoke filters. KERSHAW, W. - Nov. 25, 1954 [Dec. 24, 1953], No. 35829/53. Class 25. [Also in Group XXVIII] A device for removing solid matter from smoke has a passage adapted to communicate at its entrance end with the smoke flue or the like of combustion apparatus the passage having an orifice obturated by a filter adapted to be moved rectilinearly relative to the said orifice whereby the filter forms a moveable partition across the said passage, and means for causing a flow of smoke from the flue through the passage and the filter, which is permeable to gases and vapours but which is adapted to remove solid matter from the smoke passing therethrough. In the smoke filtering device shown in Fig. 1 a fan 26 induces smoke in a chimney 1 to pass via pipe 2 and slag or steel wool filter 5 to a filtering chamber 9. Smoke enters this chamber at orifice 11 and leaves at orifice 24 being forced in its passage therethrough to pass through one run of a continuously moving canvas endless belt 12 and a perforated guide plate 15 the latter being so tensioned by springs 16 that it keeps the moving belt against the orifice 11. The belt is mounted on rollers 13, 14, the former being motor driven and the moving belt is kept clean by a brush 21 and scraper 22 dirt therefrom being deposited in a removable container 10. Smoke leaving the chamber 9 is either passed to the atmosphere through pipe 34, or to the chimney through pipe 35 or to a water washing device 29 through a pipe 28. In a modified form of filtering chamber, Fig. 2, the smoke from the slag or steel wool filter 5 is caused to pass through both rtms of an endless belt 43 and two spring-loaded guide plates 44<SP>1</SP>. The belt is cleaned by brush 45, scraper 46 and a water bath 44. A modified form of slag or steel wool filter is shown in Fig. 3. In this embodiment smoke is extracted from the chimney by a fan 47 and the slag or steel wool 52 is held in a perforate container 53. Smoke from the pipe 51 passes to a filtering chamber such as shown in Figs. 1 and 2 the fan 47 assisting the fan 26 in moving the smoke. The motor driving the fan 26 may be provided with adjustable speed control for varying the rate of flow of the smoke. Solid deposited matter is removed from the slag or steel wool container through a door 7 of the embodiment shown in Fig. 1 and a door 55 of that shown in Fig. 3 whilst the belt 12 is removed for renewal purposes through the bottom of the casing 9 when the container 10 is removed and the belt 43 is removed from its chamber for a similar purpose through a suitable door therein. The slag or steel wool 5, 52 is renewable through doors 4<SP>1</SP> and 54 respectively.
