Patent GB-672101-A (GB)
Title: Polymerization of propylene
IPC: C07C2/18
Filed: 1950-06-02
Abstract: Propylene is intimately contacted with concentrated liquid phosphoric acid under polymerizing conditions, the products continuously led to a separating zone, the separated acid phase returned to the polymerizer, the hydrocarbon phase depropanized and fractionated to separate a product fraction boiling above 350 DEG  F., and an overhead boiling below about 350 DEG  F., which is recycled to the polymerizer, a substantial quantity of propylene polymers boiling below about 350 DEG  F. also being introduced into the polymerizer from an extraneous source.  The boiling range distribution of the product and the C12 to C15 ratio is controlled by varying the amount of extraneous polymers introduced.  This is generally equal to 0.3-0.8 of the amount of propylene charged on a liquid volume basis but may be as low as 0.1.  With a value of 0.5, the C12 to C15 ratio may be increased from 1-2 : 1 to above 5 : 1.  Such polymers yield alkyl aryl sulphonate detergents of high quality.  Propylene feed gas, after purifying and drying, is fed in part to a first polymerizer containing solid phosphoric acid catalyst at about 300-500 DEG  F., and above 200 p.s.i.g., the product being depropanized and topped to obtain a polymer fraction boiling below about 350 DEG  F.  This is passed with the rest of the propylene feed to a second polymerizer containing 103-115 per cent phosphoric acid, calculated as ortho acid, at below about 325 DEG , preferably 200-325 DEG  F., and above 200 p.s.i.g.  The hydrocarbon phase of the product passes to the same topping still as the first polymerizer product.  A bottoms fraction boiling above 350 DEG  F. passes to a rerun still where overhead of 350-500 DEG  F. is recovered as product while part of the bottoms may be returned to the first polymerizer.  Examples illustrate the increase in C12 to C15 ratio and reduction of heavy polymer formation by addition of extraneous light polymer.

Title: Delay line
Inventor: FREEDMAN NIGEL JOHN
IPC: H03H9/36
Filed: 1967-03-29
Abstract: 1,134,293. Electromechanical delay lines. MULLARD Ltd. 29 March, 1967, No. 14224/67. Heading H3U. [Also in Division H1] A single-port delay line comprises a single crystal of ferrimagnetic material which forms the dielectric of a coaxial transmission line and, at the same time, functions as a transducer and propagation medium for elastic waves. The crystal 3 may be of yttrium iron garnet (YIG) and is arranged to fill the space between the conductors of a coaxial line which is terminated in a resistive or reactive matched load 5. A further section of the line is occupied by an element 4 made of polycrystalline YIG, the total length of the YIG elements 3, 4 being L. A constant and spatially uniform external magnetic field Hext is applied to the YIG elements in the longitudinal direction of the line. Fig. 2 shows the non-uniform intensity of the resultant internal field which rises to a maximum at the central point of the elements 3, 4 and falls to a minimum value at either end (the graph shows the left-hand half only). The YIG elements 3, 4 are matched to the input section 6 and to the termination 5 respectively by dielectric members 7, 8 which may be tapered in the usual manner. An electromagnetic (e-m.) wave from the input section 6 propagates from left to right in the single crystal 3 and is transformed into a spin wave at the transverse plane where the internal field reaches a value Ht known as the turning value. The spin wave propagates from right to left and is converted to an elastic wave at the plane where the internal field has dropped to a value He known as the crossover value. The elastic wave continues to propagate to the left and is reflected by the polished end-face 9 of the crystal 3. The reverse transformations take place and a delayed e-m. wave appears at the section 6 which thus forms both input and output port. The delay may be altered by adjustment of the field to shift the planes defined by Ht and Hc. The delay path may be increased by providing a further elastic-wave propagation element to the left of the crystal 3. This must be made of a non-magnetic material of low acoustic loss, e.g. lithium niobate or sapphire. A square, instead of circular, section crystal 3 may be used.
