Abstract: Catalysts for the preparation of higher alcohols, aldehydes and ketones from lower alcohols in the vapour phase comprise a mixture of a hydrogenating or dehydrogenating metal with a dehydrating oxide or basic salt.  Hydrogenating or dehydrogenating catalysts mentioned are silver, copper, cobalt, iron and nickel; as dehydrating catalysts, the oxides of aluminium, iron, thorium, tungsten, and titanium are specified.  The mixed catalysts employed in the processes of the examples comprise alumina and silver, copper and kaolin, and thoria with copper and nickel.ALSO:Higher alcohols, aldehydes and ketones are prepared by passing the vapours of lower alcohols over heated catalysts comprising a mixture of a hydrogenating or dehydrogenating metal with a dehydrating oxide or basic salt.  Starting from single alcohols it is possible to obtain products having twice the number of carbon atoms, whilst a mixture of different alcohols gives rise to products whose number of carbon atoms equals that of the starting materials.  Hydrogenating or dehydrogenating catalysts mentioned are silver, copper, cobalt, iron and nickel; as dehydrating catalysts, the oxides of aluminium, iron, thorium, tungsten and titanium are specified.  The aldehydes or ketones resulting from the dehydrogenation of the original alcohols, together with the unaltered portion of the original alcohols, may be reintroduced into the process, or circulated through a second system containing the same catalyst.  Examples are given of the preparation of (1) 2-methylpentanol-1 from propyl alcohol using a mixture of alumina and silver; propionic aldehyde is also formed and is recirculated over the catalyst; (2) methylisobutyl ketone and carbinol from isopropyl alcohol over a mixture of thoria, copper and nickel; (3) methylpropyl ketone and methylisobutyl ketone, together with the corresponding alcohols and some butyl aldehyde, from a mixture of ethyl and isopropyl alcohols over copper and kaolin; acetaldehyde and acetone formed as intermediate products are mixed with the starting materials and passed through another tube containing the same catalyst.

Abstract: 1502151 Optical read-out beam aligner; automatic control of position PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Feb 1975 [13 Feb 1974] 5489/75 Headings G2J and G3R In a device for reading optical information on tracks 2 of a disc 1 such as that disclosed in Specification No 1452329, the fine adjustment of the position of the read-out spot V in the tangential and radial directions relative to the track are effected by way of a beam deflector 12 comprising a plano-concave lens 13 and a plano-convex lens 14. The lenses 13 or 14 are independently rotatably moved about axes (in the plane of Fig. 4 and perpendicular to the plane passing through their centres of curvature M13, M14). That is, the relative positions of the lenses 13, 14 determine the orientation of the exit beam. Each lens 13 or 14 is attached to a pair of rods 40 and 42 or 44 and 45 (45), Fig. 6 (not shown), arranged so that rotatable movement by one lens produces read-out spot movement in the radial direction, and rotatable movement by the other produces spot movement in the tangential direction. The lens movement is effected by way of filament windings, Figs. 5 and 6 (not shown) attached to the lenses which are positioned between the poles of a permanent magnet. When a signal (Sr, St) proportional to the tracking error is fed to the filament the lenses are rotatably moved in response. Radiation from a laser 6 in the form of a read spot and two additional spots projected on to the edges of the track, is directed as shown via a semireflector 7, a lens 10, a semi-reflector 20, a reflector 11, a lens 16, the beam deflector 12 and a lens 15 on to the optical information track. The reflected light is directed back as shown on to a set of photodetectors 21a, 21b, 21c supplying a signal processing circuit which provides the tracking error signals Sr, St and the information signal Si. A further beam 31 (dotted lines) may be used to detect focusing errors. The further beam 31 is derived from the main beam 30 and passing it via a slit 17 and directing it on to the tracking surface to be reflected back, as shown, on to two further photo-diodes 18, 19. If the system is "in focus" the photo-cells 18, 19 would be identically illuminated and would therefore have equal outputs.

Abstract: 1,225,014. Heating reaction vessels with nuclear reactor coolant. KERNFORSCHUNG SANLAGE JULICH G.m.b.H. 17 Feb., 1968 [17 Feb., 1967], No. 5717/68. Heading B1X. (Also in Division C1] Energy from a nuclear reactor is stored in the form of a chemical substance whose production requires a supply of water vapour by circulating a coolant from a nuclear reactor through an evaporator and one or more chemical reaction vessels to heat the or one of said vessels to a temperature between 400 and 600C, supplying water vapour from the evaporator to the vessel so heated, and effecting a chemical reaction therein to produce the desired chemical substance. As shown coolant is passed via piping 10 through reaction vessels 2, 3, 4 and an evaporator 5, the heat transferred thereto and the temperatures achieved being controlled by appropriate throttling of the coolant flow. As described the vessel 2 which is heated to 400 to 600C contains a metal oxide such as CaO or MgO in granule form and is supplied with CO and with water vapour from evaporator 5 via pipe 6 to form hydrogen which is extracted via conduit 8. By means of conduits 12, 13 the metal carbonate by-product is driven into vessel 3, which is heated to 700 to 800C for CaCO 3  or to 900 to 1000C for MgCO 3 , to decompose it to the metal oxide which is driven back into vessel 2, while a part of the CO 2  produced is passed via conduit 9 to a vessel 4 which is heated to 900 to 1000C and contains crushed coke so that CO is formed and this is returned via conduit 7 to the vessel 2. Instead of coke, vessel 4 may contain as reductant a hydrocarbon, while instead of using three separate vessels the chemical reactions may be effected in suitably connected separate zones within a single container. In an alternative arrangement, vessels 2 and 3 each act in turn as hydrogen-producing and carbonate decomposing vessels, the evaporator being connected to them alternately with suitable control of the sequence of heating of the two vessels.

Abstract: 837,113. Extruding. LOEWY ENGINEERING CO. Ltd. Feb. 19, 1958 [Feb. 21, 1957; Sept. 25, 1957], Nos. 5893/57 and 30094/57. Class 83 (4). A pull-out device for pulling extruded strands S issuing from an extrusion press comprises a gripper head 20 having a plurality of contiguous gripper plates 41, 42 with apertures 43, 44 movable into alignment for receiving the strands, and means for relatively rotating adjacent plates to bring the apertures out of alignment and cause them to crimp and grip the strands, Fig. 2a (not shown). The head 20 passes through a tunnel exit 25 in the press bolster up to the surface 30 of the die backing ring 28 which has passages 29 for the extruded strands; the head is connected by a tube 21 to a carriage movable along a run-out table. The gripper plates 41, 42 are mounted on an arbor 55 backed by a spring-loaded sleeve 57 and have lugs 53 engaging respectively in oppositelyinclined helical grooves 51, 52 in a housing 32. When the head is in the extreme right-hand position spring 62 has been compressed and the apertures 43, 44 are in alignment to receive the strands S whose passage through the apertures is signalled to the operator by their engagement with signalling blades 71. These blades may operate an interlock in the drive of the pull-out device. The head 20 then moves to the left, whereupon spring 62 expands, causing relative axial movement between the lugs 53 and helical grooves 51, 52. This effects a slight rotation of the plates 41, 42 in opposite directions, causing their apertures to grip the strands. The strands are released by pulling on an operating- rod 63 which may be actuated manually or by a stop on the machine. Only one set of gripper plates need be rotated whilst the other set remain stationary. In another embodiment, Fig. 3, the gripper plates are rotated by cam grooves in an operating head remote from the plates.
