Patent GB-558881-A (GB)
Abstract: 558,881. Modified fatty acids and fatty oils. STEVENS, A. H. (American Cyanamid Co.). Oct. 15, 1941, No. 13286. [Class 91] [Also in Group IV] Polyunsaturated higher fatty acids containing at least two and preferably non-conjugated double bonds are isomerised to bring about a substantial content of conjugated double bonds therein by heating an aqueous solution of their soaps and an excess of alkali in a closed chamber at temperatures of about 200‹-250‹ C. and under the corresponding autogenic pressure. The process may be applied directly to oils containing the glycerides of such acids, such as oils of iodine number of at least 110 e.g. vegetable and fish oils. Linseed, soya bean, and cottonseed oil are specified amongst others. The process may be applied to such acids in which a proportion of the double bonds are already in the conjugated position, the products obtained containing an increased proportion thereof e.g. dehydrated castor oil fatty acids. The process is not advantageous with eleostearic acid or oils containing its glycerides, such as tung or oiticica oil. The isomerised fatty acids are liberated from their soaps, such as by acidifying with HCl, and these acids may then be re-esterified with a polyhydric alcohol containing at least three esterifiable hydroxy groups, such as glycerol, pentaerythritol, or dipentaerythritol, to give improved drying oils. The content of polyunsaturated fatty acids in the initial fatty acid mixture, e.g. soya bean fatty acids may be increased by preliminarily separating out the more saturated fatty acids, stearic acid &c. such as by cooling the mixture and filtering off the crystallized saturated acids. The content of conjugated double bond fatty acids may also be increased by vacuum distillation of the isomerised fatty acid mixture to give fractions richer in conjugated acids. In the numerous examples given starting with the fatty acid mixtures specified above, isomerised fatty acid mixtures are obtained containing substantial proportions of 9, 11-octadecadienic acid 1 and 10, 12, 14-octadecatrienic acid. Besides caustic soda and caustic potash, lithium hydroxide is specified for effecting the isomerisation. The isomerised fatty acids may be used for preparing modified alkyd resins by heating mixtures of phthalic anhydride, glycerine and the isomerised acids, the acids specified comprising isomerised linseed fatty acids, isomerised soya bean fatty acids, and isomerised fish oil fatty acids respectively. Specification 561,803 is referred to. Reference has been directed by the Comptroller to Specification 561,803.

Title: Process for producing Carbon Black
IPC: C09C1/50
Filed: 1966-12-20
Abstract: 1,177,756. Carbon black. PHILLIPS PETROLEUM CO. 20 Dec., 1966 [20 Dec., 1965; 27 June, 1966; 29 Sept., 1966], No. 56968/66. Heading C1A. Carbon black may be produced, by partial combustion and/or pyrolysis of a hydrocarbon feedstock, by introducing a first stream of a free oxygen-containing gas into the upstream end portion of a generally cylindrical first zone having a length greater than its diameter, introducing a stream of the feedstock into the first zone and into the free-oxygen-containing gas therein between the point of introduction of the free-oxygen-containing gas, and the downstream end of the first zone; passing the mixture from the first zone to a second generally cylindrical zone having a diameter greater than its length and greater than the diameter of the first zone, the upstream end of the second zone being in open communication with, and axially aligned with the downstream end of the first zone; introducing a second stream of gas containing free oxygen into the periphery of the second zone to establish a mass of gas around the mixture from the first zone; feeding a fuel to the first and/or second zones, and burning the fuel; passing the mixture from the second zone into a generally cylindrical third zone having a length greater than its diameter, and a diameter less than the diameter of the second zone; and separating said carbon black from the gaseous effluent from said third zone, the free oxygen in the first stream constituting 15-70% by volume of the total oxygen contained in the two streams together. Fuel may be introduced into the first zone at a point between the introduction of oxygen-containing gas, and the introduction of feedstock and preferably radially outwards from the axis of the zone. The feedstock may be introduced into the first zone at a point spaced 0À5-1À7 times the diameter of the first zone from the downstream end. The stream of O2-containing gas may be introduced tangentially into the second zone. This stream may be a stream of hot combustion gases, obtained by burning fuel in a gas which provides an excess of O2. The second stream of gas containing O2, i.e. the stream introduced into the second zone-may be introduced by a combustion tunnel in open communication with the second zone. The fuel may be introduced into the gas stream at a point between a point inside the tunnel, not more than 2 tunnel diameters (T.D.), pref. 1-1 T.D., from the outlet, and a point outside the tunnel, but in the second zone, not more than 1 T.D., pref. 0À5 T.D., from the outlet, and ignited when so introduced. The oxygen-containing gas may be air. Apparatus suitable for the process is described herein, but claimed in Specification 1,177,757.

Title: Rotary stepped joint for waveguides
IPC: F16C17/04
Filed: 1972-12-15
Abstract: 1382188 Waveguide rotary joints ELETTRONICA ASTER SrL 15 Dec 1972 [13 Sept 1972] 57905/72 Heading H1W The separate steps of a stepped rotary joint each consist of a plate having two parts (e.g. A, B, Figs. 8 and 11) one of which (A) is made of highly conductive material and contains one or more rectangular apertures C defining waveguide sections, and the other (B) of very hard material and containing circular cylindrical apertures (e.g. 39, Fig. 8) for the accommodation of bearing balls. Fig. 7 is an "exploded'' view of a joint comprising three such steps 28, 29, 30. The diameter of the balls 37 is the same as that of the apertures 39, but exceeds the thickness of the plates by a small amount whereby the balls bear on adjacent plates whilst there is no contact between the faces of the plates. Two end plates 27, 31 contain no apertures but are provided with annular rebates which provide bearing surfaces for balls 36 inserted between the end plates and a pair of interfitting casing members 33, 34 Further balls 32 are inserted between the casing and the circumferential surfaces of the plates. The plates 28, 30 may be provided with recesses 40, Figs. 7, 8, which house balls 38. If one end plate is held fixed and the other rotated through a certain angle, the intermediate plates will rotate through smaller angles defining a decreasing series, whereby the waveguide apertures form a stepped helix. The angle of rotation may be restricted to avoid interference between balls in adjacent plates. Alternatively, for the same purpose, balls in adjacent plates may lie on circles of different diameters (see Fig. 3, not shown). In the arrangement shown in Fig. 11, four waveguide paths are provided.

Title: Signal Translating System
IPC: H04N5/92
Filed: 1966-12-29
Abstract: 1,163,836. Television signal recording. RADIO CORPORATION OF AMERICA. 29 Dec., 1966 [4 Jan., 1966], No. 58238/66. Heading H4F. A television signal to be recorded and reproduced by magnetic tape apparatus has the low frequency components reduced, so as to permit the use of low frequency pre-emphasis to improve the signal to noise ratio without exceeding the dynamic range of the recording head, by an arrangement, Fig. la (not shown), in which the signal is gated under the control of waves, Figs. 3b, 3c, alternately at line rate via a direct channel, Fig. 3d, and an inverting channel, Fig. 3e, whereby upon subsequent combination of the channel signals there results a signal, Fig. 3f, 3g or 3h, in which the polarity of the signal for alternate lines is reversed. The gating operation adds a gate pulse component to the combined signal and control of the amplitude of this component permits the signal to be varied over a range as illustrated in Figs. 3f, 3g and 3h. The added gate pulse component may be adjusted in amplitude so that the gate and synchronizing pulse components occupy the non-linear region of the magnetic tape transfer characteristic. A detailed circuit for adding an adjustable gate pulse component is described with reference to Fig. 4 (not shown). The signal shown in Fig. 3(g) may have the sync. tip level corresponding the zero recording head current. Gating waves, Figs. 3b, 3c, are generated by a multivibrator which is triggered by synchronizing pulses separated from the original signal. The transitions in the gating pulses are timed to coincide with the trailing edges of the synchronizing pulses. Alternative time relationships are referred to. In a first reproduction arrangement, Fig. 1b (not shown), antiphase versions of the recorded signal are reproduced, as shown at Figs. 5a and 5b, and these are translated via amplifiers which are biased so as to become transmissive only for signals above sync. tip level. The transmitted signals appear (when inverted) as shown at Figs. 5(c) and 5(d) and are combined to form a composite signal which appears (when inverted) as shown at Fig. 5e and corresponds to the original video signal, Fig. 3(a). In an alternative reproduction arrangement, Fig. 1c (not shown), the biased amplifiers are replaced by gating amplifiers controlling by gating waves obtained from a multivibrator which is synchronized by the reproduced signal. Where there is severe dissimilarity between successive lines, a flicker pattern may be caused to appear in a reproduced image. This may be avoided by resetting the phase of the polarity reversal in the signal (i.e. by resetting the multivibrator which produces the gating waves) at frame rate. The detailed disclosure of the invention is for an arrangement in which the polarity reversal is effected at line rate. The invention may be carried out, however, at any rate substantially less than the highest video frequency.

[Also in Division G3] The heating element 7 of a soldering iron is supplied from supply conductors through an S.C.R. 21 and a circuit comprising a rectifier 23 and potentiometer 20, 24, 25, 22 connected in parallel with the S.C.R. 21, the proportions of current passing through the S.C.R. 21 and the parallel circuit being determined by the temperature of the bit which is detected by component 22, the component being a thermistor. The gate of the S.C.R. 21 is connected to the tap of the potentiometer, either directly as shown or via a resistance-capacitance phase shift circuit (Fig. 2, not shown) which enables the circuit to be used over a wide range of voltages. When the iron is cold the thermistor will have a high resistance and the gate electrode of the S.C.R. will be fired in the first half cycle. The iron will therefore be heated by half wave rectified current passing through the S.C.R. until the resistance of thermistor 22 drops whereupon a minute current flows through the parallel circuit, the S.C.R. firing voltage not being reached whilst the tip termperature remains constant. The temperature of the iron is determined by the firing angle which is adjustable by resistor 20. The element 7 comprises a helical coil embedded in insulation 8 produced by depositing an alumina compound on the wire by electrophoresis.

Abstract: 1329630 Fuel injection systems for I.C. engines BENDIX CORP 22 Dec 1971 [28 Dec 1970] 59561/71 Heading G1N In an I.C. engine intermittant fuel injection system, a signal having a magnitude related to intake manifold pressure is compared with a pulse train which has a pulse duration related to engine r.p.m. and a pulse magnitude which varies in a predetermined manner to provide injection valve actuating pulses synchronized with engine rotation and having duration which vary with engine speed and intake manifold pressure. There is shown a system for controlling two groups of injection valves. A signal from an engine speed transducer 3 is applied to a pulse forming network 30 which provides pulse trains TR1, TR2 Á 1  and Á 2  in Fig. 3 to a switching network 20 and a delay pulse network 50. During the period T1 of the pulses TR1, the network 20 allows a charging current I 1 , from circuitry 10, to charge a capacitor C1, in a network 40, and a charging current I 2  to charge a capacitor C2, and during the periods T2 of the pulses TR2, I 2  to charge C1 and I 1  to charge C2 so as to provide capacitor voltages as shown by Á 5  and Á 6  in Fig. 3. The delay pulses P1, P2 cause a delay in charging by current I 1  (portion AB and A<SP>1</SP> B<SP>1</SP>), and I 1  is such that capacitor C1 or C2 is fully charged when the voltage reaches point C or C<SP>1</SP> Current I 2  causes capacitor Cl and C2 to charge in a linear manner (portion DE or D<SP>1</SP> E<SP>1</SP>). A switching network 60 passes the voltage appearing on capacitor C2 during the periods T1 and that appearing on capacitor C1 during the periods T2 to a comparator 80 to which the manifold pressure signal is also applied, which forms a reference voltage (points F and F<SP>1</SP>). Each injection valve actuating pulse in then generated between the portions DF and D<SP>1</SP> F<SP>1</SP>. (Á 8  and Á 9  in Fig.3). As shown in Fig.3, as the engine speed increases for a constant manifold pressure the points D and D<SP>1</SP> approach the points C and C<SP>1</SP> respectively, and it is only when the points D and D<SP>1</SP> are initiated on the portions BC and B<SP>1</SP> C<SP>1</SP> respectively that the injection valve actuation pulse duration increases due to the increased time between the points D and F, and D<SP>1</SP> and F<SP>1</SP> respectively. In actual practice, the manifold pressure would also change and thus vary the positions of points F and F<SP>1</SP> and thereby the injection pulse duration. Fig.7 (not shown), shows details of the circuits 10, 20, 40, 60 and 80. The characteristics of the capacitor voltages may be varied as desired, e.g. the portions BC and B<SP>1</SP> C<SP>1</SP> may be non-linear or the slope of portions DE and D<SP>1</SP> E<SP>1</SP> may be different, Fig.6 (not shown).
