Title: Pyrogenous residue-novolac fibres
IPC: D01F6/76
Filed: 1973-05-09
Abstract: 1434224 Pyrogenous residue-novolac resin fibres CARBORUNDUM CO 9 May 1973 [15 May 1972] 22114/73 Heading C3R  A fusible fibre comprising a novolac resin and a pyrogenous residue is prepared by forming a melt of the said resin and residue and fiberizing the melt. The fusible fibre can be rendered infusible by curing with formaldehyde preferably in the presence of a catalyst. The pyrogenous residue is a material selected from coal tar pitches, pitches obtained by distillation of oils, petroleum pitches, pyrogenous asphalts and distillation residues having a softening point of from 80-200‹ C., a carbon to hydrogen ratio based on weight per cent of from 18-25 and a beta-resin content greater than 5% wt. The novolac is a condensate of a phenolic compound, preferably phenol, and formaldehyde and contains no methylol groups. The cured fibres may be oxidized by heating in an oxidizing atmosphere, e.g. air, at a temperature of 200- 300‹ C. The preferred novolaks have a number average molecular weight of 500-1200. The fibres preferably comprise up to 40% wt. of novolak. The diameter of the fibres produced can vary from 0À1-300 microns. In the examples continuous drawn filaments and short staple fibres are produced by heating a mixture of a novolak resin and a coal tar pitch which is then fiberized. The resulting fusible filaments and fibres are rendered infusible by curing by immersing them in an aqueous solution of either (1) hydrochloric acid and paraformaldehyde, or (2) ammonium hydroxide and formaldehyde, and then heating, or by flowing HCl and paraformaldehyde gases over the fibres and heating.

IPC: G06G7/184
Filed: 1960-06-24
Abstract: 904,969. Electric analogue calculating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 26, 1961 [June 24, 1960], No. 22247/60. Class 37. [Also in Group XL (c)] A circuit arrangement for integrating alternating electric signals comprises two R/C integrating networks and two transistors of opposite type connected to shunt the capacitors of the two R/C networks on alternate half-cycles of an input signal, the base of each transistor being connected in parallel to the input and means being provided for the voltages across the capacitors to appear at a common output terminal. In Fig. 4 PNP transistor T1 and NPN transistor T2 shunt the capacitors C, C<SP>1</SP>, of the two integrating networks RC, R<SP>1</SP>C<SP>1</SP>. The input to the base of each transistor is via resistor R 2 , R 2 <SP>1</SP>, respectively, from a common input terminal IT. The output for each network is taken from points J1 and J2 via resistors R 3 , R 3 <SP>1</SP> to an output terminal OT2. The mode of operation is such that the positive half-cycles of the input signal turn on transistor T2, thus shunting capacitor C<SP>1</SP>, the voltage across capacitor C appearing at the output terminal OT2 whilst the negative half-cycle of the input signal turns on transistor T1, shunting capacitor C and allowing capacitor C<SP>1</SP> to feed the output terminal OT2. In a modification (Fig. 5, not shown) two emitter followers using transistors of opposite type are used to feed the switching transistors. The arrangement may be used in the stabilization of servo systems which operate in response to integrated sinusoidal error signals.

Title: Improvements in or relating to gearing for internal combustion locomotives and other purposes
IPC: F16H63/30
Filed: 1924-09-22
Abstract: 222,153. Magnet - Werk Ges. Eisenach, (Assignees of Mrongovius, E., and Schweter, E.). Sept. 22, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Controlling different functions by same handle or lever.-In an internal-combustion engine locomotive in which the main clutch and the changespeed gear clutches are electromagnetically controlled the large main clutch 20 mav be arranged to slip before the smaller gear clutches when changes of speed are being made, the two sets of clutches being controlled by one handle. The main clutch is operated by a battery 27 through a resistance 32 controlled by the relative positions of a disc 29 and a handle 33. The gear clutches 7 are operated by a battery 39 through contacts 36 on the handle. The disc is retarded by a dash-pot 41 and is connected to the handle by a spring 40. In the position shown the main clutch is engaged and the others are free. To engage the first gear clutch the handle is rotated counterclockwise and so completes the circuit through the first contact 37 and energizes the corresponding gear clutch. The disc 29 has lagged behind the handle due to the action of the dashpot and thus a part of the resistance 32 is temporarily inserted in the circuit of the clutch 20 so that the action of this clutch is weakened and any slipping that occurs takes place in this clutch. The spring 40 then gradually overcomes the dashpot resistance and cuts out the resistance 32. A similar action takes place when the handle 33 is moved further to energize the next and succeeding gear clutches.
Patent GB-1077946-A (GB)
Title: Improvements in and relating to special effects apparatus for television
IPC: H04N9/76
Filed: 1965-05-26
Abstract: 1,077,946. Colour television. COMPAGNIE FRANCAISE DE TELIVISION. May 26, 1965 [May 28, 1964], No. 22463/65. Heading H4F. The invention relates to a fade-over or signal combining apparatus for use with SECAM (R.T.M.) signals in which the luminance components of two signals applied at terminals 101 and 201 are applied through circuits 112, 212 to a first fadeover or combining circuit 5, whilst the subcarrier components are separated by filters 105, 205 and applied through demodulators 106, 206 to a second fade-over or combining circuit 6, a resultant or composite signal being obtained via a circuit 7. The two original signals are synchronized as regards their line and frame blanking, but may not be in phase as regards the line frequency alternation of the two colour signals modulated on each subcarrier. It is the object of the invention automatically to remove any such phase difference. To this end each colour signal channel between filter and demodulator includes a pair of switches 113, 115 and 213, 215 whereby the signal may be sent through a one-line-duration delay circuit 4 instead of a direct non-delay circuit 114, 214. A circuit 107, 207 associated with each channel is driven by line blanking pulses from connection 3 and responds to the normal colour identification signals included in the blanking intervals to produce a square wave signal of half line frequency whose phase indicates the phase of colour alternation. A reference square wave is generated by a circuit 2 in response to local colour control signals obtained from connection 1. This wave is then compared with the waves from circuits 107 and 207 in adders 108 and 208. The square waves are arranged to be of equal amplitude whereby an adder output is zero if the associated colour signal phase is incorrect. The adder outputs are applied through diodes 109, 209 to integrator circuits 110. 111; 210, 211 whose outputs control the switches in the respective channels. The operation is such that the delay circuit 4 is introduced in response to zero output from an adder. Due to the use of a common delay circuit 4, the arrangement may correct the phase of only one colour signal, although the correction may be applied to either signal. A modification, Fig. 2 (not shown), employs a separate delay for each channel so that both signals may be corrected. With this modification, signals for circuits 107 and 207 may be obtained from the outputs of the associated direct and delayed channels to avoid the use of delay elements in the circuits. Where one signal source is synchronized locally and therefore has the correct phase of colour alternation, one half of the arrangement shown in block A, Fig. 1, may be dispensed with.

A process for the pyrolytic production of carbon black from a hydrocarbon feedstock wherein a combustible mixture of fuel and freeoxygen-containing gas is burnt in at least one primary combustion zone 20, 20<SP>1</SP> (Fig. 2) and the combustion mixture then passed tangentially into a further combustion zone 18 and thence into a reaction zone 11 (Fig. 1), is characterized in that at least some of the hydrocarbon feedstock is introduced into the primary combustion zone(s) 20, 20<SP>1</SP> downstream of the fuel and free oxygen-containing gas, the remainder, if any, being introduced into the further combustion zone 18. Fig. 2 is a crosssection taken along the line 2-2 of Fig. 1, and depicts the embodiment wherein the primary combustion zones are two in number, 20, 20<SP>1</SP>, and combustion gases therefrom are fed tangentially into further combustion zone 18 at diametrically opposed areas on the periphery thereof. Into the primary combustion zone(s) are fed (a) free oxygen-containing gas (e.g. air) via conduits 29, 30, emerging through orifices 38, (b) a fuel via conduit 40 and (c) hydrocarbon feedstock via inner conduit 44 which is positioned longitudinally within conduit 40, with its outlet extending beyond the outlet end of conduit 40. Fig. 3, which is an enlarged view, partly in cross-section, of the fuel and hydrocarbon inlets, depicts the embodiment wherein conduit 40 is closed at 48 and the fuel escapes therefrom through radially disposed openings 50, and wherein hydrocarbon feedstock from conduit 44 is sprayed into primary combustion zone(s) 20, 20<SP>1</SP> via nozzle 52. The proportion of the hydrocarbon feedstock fed to the primary combustion zone(s) is preferably 10-100 vol per cent of the total, and where these zones are two in number the feedstock is optionally fed thereto in unequal amounts. The remainder, if any, of the hydrocarbon feedstock is injected axially into the rotating mass of hot combustion gases in further combustion zone 18 through conduit 22 which is surrounded by conduit 24 through which air is optionally passed. Further combustion zone 18 must be generally cylindrical with a diameter greater than its length, and axially aligned cylindrical reaction zone 11 must have a diameter less than its length and less than the diameter of further combustion zone 18, although the downstream end of reaction zone 11 optionally has an enlarged diameter. The helically-flowing mixture in reaction zone 11 is cooled by water introduced through conduits 15, 17 before being passed to carbon black recovery equipment (not shown). The hydrocarbon feedstock may be gaseous, but is preferably liquid, and a number of types are listed. The fuel may be liquid or solid, but is preferably gaseous, e.g. natural gas.
