Abstract: 1437150 Hydrocyanation of 3- or 4-pentenenitrile E I DU PONT DE NEMOURS & CO 1 Oct 1974 [2 Oct 1973] 42498/74 Heading C2C 3- or 4-pentenenitrile is hydrocyanated at 0À5-100 atm. in the presence of a zero valent nickel complex selected from Ni(PXYZ) 4 , N-bonded nitrile complexes Ni(PXYZ) 3 R<SP>2</SP>CN and olefin-bonded complexes Ni(PXYZ) 2 A, where X is OR and Y and Z are R or OR, R is C 1 -C 18  alkyl or aryl, R<SP>2</SP> is 2-butenyl, 3-butenyl or a cyano-substituted alkyl radical, A is 3- or 4-pentenenitrile, and the R radicals in the nitrile or olefin complexes are so chosen that the liquid has a cone angle of 130-170 degrees; the mole ratio of mononitrile to nickel complex is between 1 : 5 and 2000 : 1; the catalyst in solution is contacted at 0-100‹ C. with an activated substantially water-free crystalline metal alumino-slilcate zerolite molecular sieve having substantially uniform pores in the range 3Š to 13Š. The zeolite preferably has the formula where M is an alkali or alkaline earth metal, n is the valence of the metal, x is 2-2À5 and y is up to 10; Types 3A, 4A, 5A, 10X and 13X zeolites are suitable. The catalyst may be contacted with the zeolite in the reaction medium or before being introduced thereto; the catalyst solution may be removed from the reactor after use, contacted with the zeolite, and then returned to the hydrocyanation medium. Activition is by heating at 100-350‹ C. optionally under preduced pressure. A promoter, e.g. a salt as listed, or an organoboron compound, may be present. Suitable ligands with the prescribed cone angle are tri-o-tolyl phosphite. tri-(2,5- xylyl)phosphite, tri - (2,4 - xylyl)phosphite, tri - (o - phenylphenyl)phosphite, diphenyl phenyl phosphonite, di-o-tolyl phenyl phosphinite and phenyl diphenyl phosphinite. Other ligands suitable for the complex Ni- (PXYZ 4 ) are triphenyl phosphite, tri-(m- and pmethoxy)phenyl phosphite, tri-m-tolyl phosphite, tri-p-tolyl phosphite, tri-o-tolyl phosphite, and tri-(mamd p-tolyl)phosphite. An excess of ligand over that in the complex is preferably present. In the examples the catalyst was or was of unspecified structure prepared in situ by reduction of nickel chloride with zinc dust in a mixture of 3-pentenenitrile and mixed m and p-tritolyl phosphites; zinc chloride or triphenyl borane was present as promoter. The main product was adiponitrile with a smaller amount of methylglutaronitrile and very little ethylsuccinonitrile. Reference has been directed by the Comptroller to Specifications 1,104,140; 1,146,330; 1,174,716; 1,178,950; 1,377,228 and 1,394,134.

Abstract: 1,179,977. Thyristor firing circuits. BROWN, BOVERI & CO. Ltd. 6 Sept., 1968 [8 Sept., 1967], No. 42514/68. Heading H3T. In a pulse generator having two parallel connected branches, one branch includes a resistor R1 in series with a thyristor T1 and diode D1 inversely connect across the thyristor T1, the other branch includes a resistor R2, diode D2, thyristor T2 and primary winding AB of a pulse transformer for firing a thyristor, and capacitors C1, C2 and a resistor R3 are connected as shown with a resistor R4 connected to a terminal for connection to a voltage U2 higher than that U1 connected to the parallel branches. When thyristor T1 is ON capacitors C1 and C2 charge via T1, R2, inductor La and T1, R3, R4 respectively. Then if T2 is fired ON these capacitors C1 and C2 discharge via T2 and the pulse transformer AB and thyristor T1 turns OFF. The extinction of T1 does not affect the discharging of C2 since capacitor Q discharges via diode D1 and the combined effect of these capacitors Cl, C2 discharging produces a sharply rising firing pulse (Fig. 1, not shown), in the secondary of the pulse transformer AB. Diode D2 isolates the higher voltage U2 from the capacitor C1 and so prevents current flow through the low-resistance path R4, R2, R1 when T1 is ON. The pulse transformers AB have an auxiliary primary winding connected in series with thyristor T1 so that when it is conductive the magnetization of the cores, produced when T2 was conductive, is reversed. The circuit may be used for the simultaneous firing of a plurality of thyristors.

Abstract: 1,143,022. Endless conveyers. RUD KETTENFABRIK RIEGER & DIETZ, K.G. 28 Sept., 1966 [28 Sept., 1965], No. 43291/66. Heading B8A. In an endless chain conveyer, spaced load carrying platforms 31 (not shown in Fig. 8, which shows both plan and elevation of the conveyer chain diagrammatically in the same Figure) are maintained in a horizontal attitude all round the path of the conveyer by providing attitude maintaining chains 52, 53, 56, 57 at each end of the conveyer, in addition to the normal conveying chains 50, 51, there being means to make and break where necessary, along the conveyer path, connections between each platform 31 and the chains 52, 53. These connections are formed by pins 32 the outer end of each of which is engageable, on outward axial movement of the pin 32, with a link of the appropriate chain 52 or 53 as the case may be. The axial movement of the pin is derived from guide rails 39 on the conveyer frame, which engage a roller 38 carried by a member 40 of the pin 32. The platform 31 is connected to the chains 50, 51, by pins 35 which are permanently connected to the chains. The platform is supported by rollers 45, 47 which run on rails 46. One of the chains 52, 53 may be omitted. In a modified conveyer (Figs. 1 and 2, not shown) the only vertical component of movement of the platforms 31 is around return sprockets at each end of the conveyer. In this construction there is a single pair of auxiliary chains extending the whole length of the conveyer instead of the two separate pairs 52, 53 and 56, 57 at respective ends of the conveyer as in Fig. 8. In another modification (Fig. 10, not shown), the conveyer is of right-angled configuration in plan. There is only one conveying chain which extends over the whole path of the conveyer, and this is guided around the right-angled bend in the conveyer path, by rollers (67).

An apparatus for effecting the method comprises two tyre bead support members 48, 74 rotatably mounted on coaxial shafts 44, 70 and axially movable with the shafts towards and away from each other. The shaft 44 mounts, between the members, an X-ray source 121 in a housing 120 movable radially by means of a rack 122 and gear 130. An X-ray detection unit 18 is mounted on a pivoted table 160. A tyre delivered under gravity along a shoot 12 which is elevated from its illustrated retracted position is clamped between the support members and automatically inflated to, for example, 40 p.s.i. by air supplied from take 92. During the inflation, the members are moved apart slightly, and a motor 132 drives the gear 130 to advance the X-ray source radially into the tyre. The unit 18 is now moved by motor 162, synchronoulsy with rotation of the X-ray source by a motor 123, about the tyre while the latter is rotated by a motor driven roller 98, and the image of the tyre wall developed by the unit is amplified and optically transmitted to a television camera (not shown) in the unit. At each end of the arcuate path of the unit 18, the X-rays pass through the rims of the members 48, 74 and the power supplied to the X-ray source may be increased at those end positions in order to provide clearer images. The roller 98 is moved from an initial retracted position into engagement with a supported tyre by appropriate actuation of a ram 106. Coolant conduits 136 and an electric cable 140 pass through hollow shaft 44 to the X-ray source 121. To adapt the apparatus for a tyre having a larger bead diameter an annulus 170 is secured to each of the support members.
