Title: Improvements in electrode pitch binders
IPC: C25C3/12
Filed: 1961-07-11
Abstract: A carbon-electrode binder is obtained by heat-treating an aromatic tar obtained from the steam cracking of hydrocarbons whereby volatile constituents are removed from the said tar and the proportion of benzene-insoluble matter in the tar is increased.  The heat-treatment may be carried out at a temperature between 750 DEG  and 900 DEG F., volatile material resulting from the heat-treatment being removed overhead, or the aromatic tar may be heated to a temperature between 700 DEG  and 850 DEG F. under a pressure of from 50 to 1500 p.s.i.g., the volatiles thus formed being flashed off to a lower pressure of from 0 to 80 p.s.i.g.  The binder may include a minor proportion of a lighter hydrocarbon whereby the softening point is adjusted to a desired value, the lighter hydrocarbon may be obtained from the volatile fraction removed during the heat-treating step.

Title: Improvements in or relating to Weft Stop Motions on Looms.
IPC: D03D51/34
Filed: 1967-05-31
Abstract: 1,184,583. Loom stop motions. HEBERLEIN & CO. A.G. 31 May, 1967 [31 May, 1966; 11 May, 1967], No. 25194/67. Heading D1E. A weft stop motion for a loom comprises an electro-mechanical transducer mounted in the shuttle of a loom which is set into vibration by the unwinding of the weft from its spool and applies voltage to an inductive circuit which by an inductive coupling controls a detector circuit on the loom to generate a signal for stopping the loom if the weft breaks. As shown in Fig. 1 a resilient rod 5 engaged and vibrated by the running weft 7 is coupled by member 6 to a piezoelectric crystal 2 which generates a voltage which is applied to an oscillatory circuit (Fig. 2) which is housed in the base 1. This circuit comprises in addition to the piezo-electric crystal 2 a variable capacitance diode 8, a resistance 9, a capacitor 10 and an inductor coil 11. A detector circuit which may be mounted on the sley comprises, Fig. 3, a high-frequency generator 12 which through a resistance 13 causes a resonant circuit 14 to oscillate. An inductor coil 20 of the latter is connected to a demodulator 15 to give a fixed D.C. voltage output U when the shuttle is not in the vicinity of the detector. The impedance of the resonant circuit 8-11 varies in accordance with whether or not the rod 5 and piezoelectric crystal 2 are vibrating and accordingly, as the shuttle passes the detector, a variation in the reaction with detector circuit is obtained giving a variation in the output U which is utilised as a signal to stop the loom when the weft is broken. Instead of the piezoelectric crystal 2 other electro mechanical transducers can be used such as vibrating contacts in a resistance circuit or a magnet vibrating in a coil. Other alternative oscillatory and detector circuits are also described.

Abstract: 383,344. Prepayment mechanism for electricity meters. SOC. DES COMPTEURS DE GEN’VE, Grand Pre, Geneva, Switzerland. Sept. 9, 1931, No. 25289. Convention date, Aug. 14. Addition to 383,343. [Class 27.] Prepaying basic charges.-The friction coupling between the wheels 7, 8, which are fast and loose on the coin-operated shaft, as described in the parent Specification, is provided by a forked blade spring 50 of U-shape. When it is desired that 50 per cent of the value of the coin inserted shall go to paying the basic charge, the spring 50 is placed between the wheels 9, 10 which mesh with the wheels 7, 8 and are connected respectively to the planet pinion and to the sleeve carrying the first sun wheel of the second epicyclic gear. In a modification, Fig. 3, in which the change of the coupling between the gears may be made from the exterior of the apparatus, the pairs of wheels 7, 8 and 9, 10 are frictionally coupled by sleeves 52, 521 and 54, 54<1> slidable but non-rotatable on the shafts 3, 11 and pressed apart into coupling position by springs 53, 55 respectively. The sleeves are embraced by forked levers 56, 561 pivoted together at 57 and controlled by a spring 59 at one end so that the sleeves 52, 52<1> couple the wheels 7, 8 together, the other ends of the levers disengaging the sleeves 54, 54<1> from the wheels 9, 10. When the basic charge is to be 50 per cent of the value of the inserted coins, a cone 60 mounted on the end of a screw 61 is introduced between the ends 58, 58<1> of the levers 56, 561 to move these against the action of the spring 59, thereby disengaging the sleeve 52, 521 and engaging the sleeves 54, 541 with their respective wheels. The screw 61 is accessible from the outside of the meter through an opening closed by a small bolt when the money-box is in position.

Title: Colour stabilization of polymerizable heterocyclic nitrogen compounds
IPC: C08F26/06
Filed: 1963-06-26
Abstract: The invention comprises colour-stabilized compositions containing a polymerizable heterocyclic nitrogen compound containing one or more vinyl groups or alkyl vinyl groups and a stabilizer comprising formaldehyde or a compound which decomposes to liberate formaldehyde on contact with the nitrogen compound. Suitable compounds which liberate formaldehyde are paraformaldehyde, formalin, sodium formaldehyde sulphoxylate and methylol-ureas. The amount of formaldehyde present in the composition is preferably 0.02-15% by weight. Suitable vinyl pyridines for stabilization in this way are for example those of formula <FORM:0967156/C1/1> in which each R is hydrogen or an alkyl, vinyl, a -alkyl vinyl or b -alkylvinyl radical, at least one and not more than 2 of the groups being a vinyl or alkylvinyl group and the number of carbon atoms in any alkyl radical not exceeding 20. Other compounds which may be stabilized are vinylpyrroles, vinylpiperidines, vinylpyrrolidines, vinyl pyrrolidones, vinyl tetrahydropyridines and vinylpyrrolines as well as the a - and b -alkyl analogues of these. The stabilized compositions are obtained by adding the formaldehyde or formaldehyde-liberating compound to the pyridine derivative. A polymerization inhibitor may also be added to the mixture.

Title: Improvements relating to constant voltage rectifiers
IPC: H02M7/06
Filed: 1944-12-18
Abstract: 592,189. Rectifying alternating currents; automatic control systems. JACKSON, H. Dec. 18, 1944, No. 25420. [Classes 38 (ii) and 38 (iv)] A rectifier is supplied from the secondary of a transformer having a primary. connected to the supply in series with a reactor; and a tertiary winding supplied with D.C. saturating current obtained from the output side of the rectifier. By this means the output voltage may be maintained reasonably constant. The transformer and reactor are shown divided into two parts; the transformer primaries 20, 23 being connected in series with inductances 15, 17. Secondaries 21, 24 connected in series, supply a load at 13, 14 through a rectifier bridge 10, and tertiary windings 19, 22 are connected across the rectifier output, in series reversed connection so that the A.C. induced in them cancels out. The,supply voltage divides across , the inductances and primaries, and if the output voltage rises or falls the saturating current in tertiaries 19, 22 rises or falls so that the inductance of the primaries 20, 23 is changed and the voltage across them falls or rises respectively to reduce the variation of the output voltage. This effect may be enhanced by connecting saturating windings, 16, 18 also in series reversed connection, in series with the output. In a modification the transformer primaries are connected in parallel. To increase the controlling effect, a counter e.m.f. battery or a non-linear resistance may be connected in series with the tertiary windings. The Provisional Specification describes a rectifier arrangement in which the transformer primary is connected in parallel with a saturable reactor having a D.C. winding connected across the rectifier output, the two parallel windings being connected in series with another reactor. Also this latter reactor may have a saturating winding carrying the D.C. load current. The transformer and series reactor windings may be divided into two series connected parts, so that the saturating windings may be in series reversed connection to cancel out the induced A.C.
