Title: Improvements in the polymerisation of diolefines
IPC: C08F36/04
Filed: 1930-12-11
Abstract: The polymerization of diolefines by means of alkali or alkaline-earth metals or their alloys with one another in presence of hydrogen is effected in the absence of organic compounds containing oxygen. Organic compounds free from oxygen, such as halogen compounds may be present, and also indifferent gases such as nitrogen or carbon dioxide.  Various pressures may be used, pressures from 0,5 to 50 atmospheres being mentioned. Increasing pressures of hydrogen produce products the solutions of which show decreasing viscosities.  The temperature may be from 0 DEG  to 120 DEG  C.  In examples, butadiene is polymerized with sodium (1) in hydrogen at 2 atmospheres at 60 DEG C., the product being soft; (2) in hydrogen at 4 and 10 atmospheres respectively at 60 DEG  C., the products being a sticky fluid and a liquid respectively; (3) in hydrogen at half an atmosphere at 60 DEG C. yielding a tough rubber-like product; and (4) in presence of a small quantity of vinyl chloride in hydrogen at half an atmosphere at 60 DEG  C. yielding a soft plastic product.

Abstract: 1,173,161. Photo-electric monitoring of crucible wall. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. Aug. 11, 1967 [Aug.24, 1966], No.37985/66. Heading G1A. In an apparatus and a method for indicating excessive melting of the crucible wall in the consumable electrode arc melting of metal, radiation emitted by the wall or by metal liquefied or vaporized during the process is monitored. Radiation from the wall may be segregated mechanically, or at least one wavelength or band of wavelengths may be chosen from the emission spectrum of the wall material. Alternatively the vapour within the crucible may be extracted and fed to an electrical discharge cell the optical radiation from which may be selectively monitored. Radiation from a port 5 viewing the annulus between the charge and the crucible is applied through lenses and slits to a photo-cell 10 which may be a photo-multiplier and the output is fed to a bridge 13 for comparison with a reference voltage, or with a voltage from one or more other spectral lines from the same area selected to compensate for variations which are common to the metal being melted and the crucible metal. The bridge unbalance is measured in a unit 20, and is integrated in a unit 22 for different selectable periods e.g. 1/10, 1 or 10 seconds and an alarm 30, 31, and possibly furnace shut-down equipment are operated if the integrated figure exceeds the corresponding standard injected by unit 26. The beams from viewer 5 may be split by an inclined mirror system, a refractory prism, or a diffraction grating and in the case of the mirrors fed to a pair of photo-multipliers through a respective pair of filters. The Specification describes the melting of titanium in a two stage process, and the use of copper, stainless steel, or aluminium, water-cooled crucibles. An inert gas may be injected in the vicinity of the viewing ports or the ports may be segments of a rotatable window to prevent fogging, and marker elements such as cadmium may be introduced into the wall for recognition by the monitoring system.

As shown, the comparing means comprise a series of comparators 52A-52N which compare each pulse amplitude with different references derived from a voltage divider chain comprising resistors 56a-56n, to provide the digital signals. Each output line of the de-coder 62 includes a respective resistor 64a-64n, the values of these resistors having a linear relationship, a logarithmic relationship, or a relationship corresponding to the voltage-brightness curve of the display tube. Pulses which fall into a first, low amplitude range generate a signal from the de-coder 62 for energizing the blue gun of the colour display, pulses on a middle amplitude range cause the green gun to be energized, and pulses in a high amplitude range cause the red gun to be energized. A colour display tube of the single gun type may alternatively be used. To improve the quality of spot on the display, the transducer, eg a Piezo-electric transducer 80, is energized by the circuit shown in Fig. 3. A first trigger circuit 84 causes energization of the transducer, and after a delay provided by unit 86, a second trigger circuit 85 applies a second energizing pulse to the transducer. This pulse coincides with the second positive oscillatory swing of the transducer output signal and is stated to cause damping of the transducer oscillations and improve the quality of echo pulse.

Abstract: 971,757. Colour television. SONY CORPORATION. Oct. 27, 1961, No. 38610/61. Drawings to Specification. Heading H4F. In a magnetic recording system for N.T.S.C. colour television signals, the Y component signal is recorded on one track with the aid of a first recording head, whilst the I and Q signals are caused to occupy separate frequency bands and are then recorded on another track with the aid of a second recording head. The Y signal is restricted if desired to a bandwidth of 3.0 Mc/s. The Q signal (of 0.5 Mc/s. bandwidth) is amplitude modulated on a 2.0 Mc/s. carrier so as to occupy a band (2.0 Mc/s. Œ 0.5 Mc/s.) located above the band (0-1.5 Mc/s.) allotted to the I signal. Prior to actual recording the signals frequency modulate carrier signals in the conventional manner. During reproduction (by apparatus which is described, but forms no part of the invention), the Y signal is obtained directly from the first head whilst the I and Q signals are obtained from the second head by first separating the I signal from 2.0 Mc/s. carrier and then be demodulating the carrier to obtain the Q signal.
