Title: Recovery of isoprene by fractionation and extractive distillation
IPC: C07C7/08
Filed: 1959-06-09
Abstract: Isoprene is separated from hydrocarbon mixtures also containing cyclopentadiene by distilling to obtain a fraction containing isoprene and some cyclopentadiene, extractively distilling to obtain a diolefine concentrate, dimerising the cyclopentadiene and fractionating to recover purified isoprene.  A C4-C9 fraction, e.g. obtained by steam cracking is heat soaked at 180-240 DEG F. for 1-30 hours to dimerise cyclodienes and fractionated to obtain overhead a fraction containing isoprene and 1-3% cyclopentadiene.  This fraction is extractively distilled, e.g. using aqueous acetone or acetonitrile containing 5-15% of water. The diolefine concentrate obtained containing 4-10% of cyclopentadiene is water washed and heat soaked at 150-300 DEG F. to dimerise cyclopentadiene.  The final fractiontion should yield a product containing at least 92% isoprene and less than 1% cyclopentadiene.

Title: Improvements in or relating to magnetic memory stores
Inventor: COOKE PHILIP
IPC: G11C11/06
Filed: 1961-06-02
Abstract: 1,032,921. Circuits employing bi-stable magnetic elements. PLESSEY CO. Ltd. Aug. 24, 1962 [June 2, 1961], No. 19988/61. Heading H3B. A two-core-per-bit word organized memory has two digit drive wires for each core pair, one 5a to drive the first core A 1  to a different state to store a " ONE " and the other 5b to drive the second core B 1  to the corresponding state to store a " ZERO." Each core is also linked by a word bias line 4 and a word drive line 1 which transmits write and read pulses from a core 7 of a matrix of switch cores. A sense winding 6 links corresponding digits of all the words and senses the difference of the outputs of two cores which are read. The sense winding 6 is crossed relative to the digit drive wires 5a and 5b halfway along to reduce the coupling between it and the wires 5a and 5b. The reversal of the output signals from half the cores is compensated in the associated logic. The memory cores are not operated between the two saturated states as the length of the write pulse produced by changing the flux in a switch core 7 by drive currents in windings 9 and 10 overcoming bias current in winding 8 is limited by resistor 3 so that only partial switching takes place. A read pulse is produced by the bias current in winding 8 after removal of the X and Y drive currents in windings 9 and 10. A suitable driving circuit for the switch matrix is also described (Fig. 5, not shown).

Title: Composite moulded articles and processes for making the same
Filed: 1932-07-15
Abstract: To produce composite moulded articles comprising a metallic portion and a portion of polymerized products of vinyl compounds with or without fillers such as cellulose, alkaline earth, metal salts of fatty acids, or natural or artificial acid resins, and also with or without fluxing agents such as carnauba wax, the metallic portion is treated by etching, plating or sizing with a priming agent to cause the vinyl compound to adhere thereto on the application of heat and pressure.  The vinyl compound is applied to the treated metal, with or without the interposition of one or more layers of vinyl-impregnated paper, sufficient heat and pressure applied to cause the compound to flow form the moulded article, and the whole then cooled under pressure.  The metal may also be formed with undercut holes or recesses to interlock with the composition.  As sizing materials for treating the metal, paracumarone resin (a thermoplastic adhesive rubber derivative) and resins of the glypal type may be used.  The invention can be used in making compounds of more than two ingredients, for example a metal or metal foil, a fibrous layer and a vinyl resin. In the latter case a reinforced vinyl resin layer may be moulded round a resin-impregnated core of pulp board or the like.  An automobile steering-wheel may be made by moulding the vinyl compound round a metal skeleton form.  The Specification also covers a composite article comprising an untreated metallic portion and a vinyl resin portion, other than one containing a plasticizer comprising a phenolic compound or an ester or ether of a phenolic compound.  The subject-matter of Specification 372,327 is disclaimed.
