Title: Aromatising unsaturated hydrocarbons
IPC: C07C2/76
Filed: 1976-06-11
Abstract: 1507778 Aromatizing unsaturated hydrocarbons BRITISH PETROLEUM CO Ltd 5 July 1976 [17 July 1975 20 Nov 1975 11 June 1976] 27979/76 27978/76 and 24297/76 Divided out of 1507549 Heading C5E  Aromatic hydrocarbons are produced by subjecting an unsaturated hydrocarbon having at least 6 carbon atoms to aromatization in the presence of a catalyst comprising elemental gallium or a compound of gallium deposited on a support. The unsaturated hydrocarbon starting material may be produced by dimerising a C 3 -C 8  monolefin, which may itself be produced by dehydrogenating a C 3 -C 8  saturated hydrocarbon, each of these reactions being carried out in the presence of the aromatization catalyst containing gallium. The three reactions may be carried out in a single step in one reactor. The catalyst support may be Al 2 O 3 , SiO 2 , activated carbon or refractory gallium oxide. Alumina and silica supports having surface hydroxy groups may have them ion-exchanged with gallium and optionally Al, Fe or Ni.

Abstract: 245,843. Robinson, S. H., Robinson, W. H., and Gough, T. C. Oct. 15, 1924. Power hammers.-In a friction-lift drop hammer of the type in which the gripping-member which presses the suspension strap against the driving-pulley is applied over the top of the pulley centrally of its shaft and is provided with a roller contacting surface working in the groove of the pulley, the gripping-member is pulled down on to the strap by coiled springs applied to rods hanging from the ends of a beam resting against the gripping-member and the latter is lifted to release the strap by a lever disposed above the beam, which lever is connected with devices for automatically releasing and renewing the pressure and for independent foot or hand operation. The lifting-strap a of the hammer x is pressed against the periphery of the pulley c by a segmental block d having rollers on its underside, a beam g resting on the block and urging it downwardly by means of spring-pressed rods g<2>. At the top of its lift the hammer strikes a release lever k connected by an adjustable link j to a lever i shackled at h to the block d whereby the latter is released from the strap allowing the hammer to drop. At the end of its descent the hammer strikes another lever o connected by a link n to the lever k, the block d thereupon gripping the strap against the pulley causing another lift of the hammer. The block d may be released from the strap by a hand or foot lever m connected by a link l to the lever i.

[Class 132 (iii)] A spinning top of the type intended to be set in rotation by hand spins first on that portion of the body opposite to a radial stem 5 and then after the stages shown in Figs. 3-6 spins on its stem (Fig. 7). In one form the top has a body whose outer surface shape is that of a sphere with a stem projecting therefrom and in which the centre of gravity of the top is located at a point which lies upon a continuation of the axis of the stem and which is slightly displaced from the geometrical centre of the spherical outer surface in the direction opposite to that of the stem. In another form the body 1 has an outer surface whose shape is that of a sphere from which a segment has been removed and has a stem projecting perpendicularly from the centre of the circular plane defined by the removed segmental portion and in which the centre of gravity is located as above. The embodiment in Fig. 1 has a cavity 3 which may be covered by a plate 7. The bodies may be solid or made of two shells glued together, the centre of gravity being correctly positioned by suitable proportioning of the stem and removed segment or by inserting a weight or thickening the shell diametrically opposite to the stem 5. Bands of colour may be provided on the body surface to produce colour variation effects as the top is spun and the stem may taper off into a knob at the upper part or can have the form of a cone or truncated cone.

Apparatus for feeding a consumable electrode or filler wire or strip in a welding process, comprises a rotatable circular body 3, an endless resilient band 4 arranged to press the wire or strip 1 into contact with the body over an arc of its periphery, drive means to cause rotation of the body 3 and a guide conduit 6 to receive the wire or strip as it is fed from the diverging surfaces of the band 4 and body 3. The apparatus may include means for detecting a blockage or restriction of the feed comprising a hollow detector conduit, e.g. a spring 2 through which the wire 1 passes, the spring 2 being mounted between insulating blocks 3 and being connected to an electrical contact 4; deflection of the wire into contact with the spring due, e.g. to a blockage completes a circuit from electrical contact 5 which may be employed to cut off the power supply, stop the feed and/or operate a warning signal. Alternatively lateral displacement of the wire or strip towards the wall of the conduit may be used to alter the inductance or capacitance of an electrical circuit in order to produce an electrical signal indicating a restriction to the feed.
