Title: Preparation of 1-alkenes
IPC: B01J23/02
Filed: 1961-12-28
Abstract: Compounded C5 to C12 1-alkenes are prepared by the homo- and heteropolymerization of 1-alkenes containing less than six carbon atoms using a catalyst composition comprising potassium, rubidium or cesium and/or a hydride and/or an organometallic derivative thereof supported upon a crystalline porous metal silicate at 65 DEG  to 200 DEG  C.  Specified alkenes are propene, 1-butene, isobutene, 1-pentene, 2-methyl-1-butene, 2-methyl-3-butene, combinations of any two of the above or of one of the above with ethene.

The term "porous silicate" is defined as a silicate having a surface area in square metres per gram of about 0,3 and greater.  Specified organo-metallic derivatives are the allyl, cyclohexyl, propyl and amyl derivatives.  Preferred silicates are those of alkali metal and alkalene earth metals having atomic numbers below 57, especially the synthetic silicates obtained by the hydrothermal treatment of silicas, with hydrated metal oxides.  Examples of the supports are talc, clinoenstatite, phenacite, bertrandite, anorthite, wollastonite, pseudo-wollastonite, the celkates, the silones, the microcels, macrocline, mullite, muscovite, orthoclose, willermite, and hernimorphite.

Abstract: 1,149,203. Registering printing plates. TAYLOR WEEKS & PARTNER Ltd. 22 Feb., 1967 [20 Oct., 1966], No. 46930/66. Heading B6C. A method of laying printing plates or blocks on to a backing sheet or a forme comprises placing a layout or copy on a layout board; setting up a backing sheet or forme to receive the plates in such a way that the layout board and the backing sheet are movable into or out of an operative position; obtaining an image of the plate, which is attached to a holder, on a transparent image transfer sheet; superimposing this image on its counterpart on the layout; and with the holder, the plate and the image transfer sheet in correct alignment, transferring the plate from the holder to the backing sheet or forme. Fig. 1 illustrates a layout, indicated generally at L, in position on a layout board 1, the board being enclosed by a metal frame 2 holding a protective cover sheet 2<SP>1</SP>; a backing sheet or forme 3 is mounted by means of a clamp 4 and hinges 5, so as to be movable in and out of contact with the layout board. Fig. 2 illustrates the plate holding and transfer device which consists of two frames 6 and 7 preferably in register by means of hinge 8; " transfer " frame 7 is provided with a sheet of transparent film or tracing material 9; " holder " frame 6 is provided with a sheet of copying material, e.g. carbon paper, to the back of which is adhered a plate, face down. In use, the layout is placed on board 1, secured by adhesive tape and covered with protective sheet 2<SP>1</SP>; each plate is then backed with double-sided contact adhesive, and laid face downwards on the back of copying material held in frame 6; the frames 6 and 7 are closed and turned over so that the plate becomes face up beneath the frames; an image of the plate is transferred to transparent sheet 9 by rubbing; the frames 6, 7 are opened and the transfer frame 7 carrying the image is located exactly over the layout and held by adhesive strips; the frames 6, 7 are then again closed so that the plate is face down over, and in register with, the layout; finally the plate is transferred to the backing sheet 3 by lowering the backing sheet on to the adhesive coating of the plate. Alternatively the cover frame 2 may be lifted into contact with the sheet 3. The plate holding and transfer device may be modified so that the holding frame is of a size to fit within the confines of the transfer frame (Fig. 6, not shown); or may consist of three frames, the two outer frames being hinged to opposite sides of the centre frame and being respectively provided with the holding sheet and a siliconized release sheet, the central frame holding the image transfer sheet (Fig. 8, not shown). A further alternative involves the use of two sheets in the holding frame (Fig. 7, not shown), one a siliconized release sheet and the second a plastic or metal plate-holding sheet, to the second of which sheets the plate is transferred after imaging so that it is held face down prior to transfer to the backing sheet or forme 3.

Abstract: 1,024,877. Sterilizing liquids. ALFALAVAL A.B. Nov. 28, 1963 [Dec. 21, 1962], No. 47016/63. Heading A2D. In the heat-treatment of a liquid, such as the sterilization of milk, by first indirectly preheating it, thereafter heating it to a pre-determined temperature by direct mixing with steam and finally cooling the heattreated liquid to a temperature which is innocuous for the liquid by a rapid pressure drop under evaporation in an exhausted expansion vessel, the liquid is indirectly pre-heated to a constant temperature and the difference between the temperature of the liquid prior to direct mixing with steam and after the pressure drop during evaporation is kept at a pre-determined value by controlling the pressure (vacuum) at which the evaporation occurs, such that the quantity of water withdrawn from the liquid by the evaporation due to the pressure drop is identical with that supplied by the steam as condensate. The liquid may be diverted to a return system as described in Specification 967,125 should the predetermined temperature be not reached.

Abstract: 1,241,173. Roller conveyers. PATERSON HUGHES ENG. CO. Ltd. 18 Sept., 1968 [20 Oct., 1967], No. 47841/67. Heading B8A. [Also in Division F2] A roller assembly for use in a powered roller conveyer comprises a continuously driven spindle 1 which, by means of a slipping friction clutch 4, drives a roller 2 rotatable on the spindle. The clutch comprises shoes 5 pivoted at 6 to a collar or housing 7 fixed to the spindle, the shoes being pressed into contact with the inner surface of the roller 2 by helical springs 9. The pressure exerted by the shoes is predetermined by the choice of the springs 9 and by the location of the springs in one of three sockets 10, 11, 12 of different depths. Suitable selection of spring pressure enables only sufficient torque to be transmitted to the rollers to move the loads carried on the conveyer. The loads may however be held in check at any point required. When a further conveyer, e.g. at right angles to the main conveyer is provided, a part of the load may be brought to rest by a mechanical arm, with the rollers stationary and the clutches slipping, the load then being removed, e.g. to the second conveyer. Idle rollers may be interspersed with rollers having clutches.

Filed: 1971-10-15
Abstract: 1363262 Diffraction gratings XEROX CORP 15 Oct 1971 [15 Oct 1970] 48065/71 Heading G2J A diffraction grating is formed by exposing a uniform coating of photo-resist 15 on a substrate 14 to a pattern of light interference fringes 29, developing the photo-resist to remove unexposed material and then metallizing the resultant ridge bearing surface. The metal coated ridges are then stripped away to leave a grating comprising a periodic array of fine metal strips on the substrate. The metal may be vapour deposited chromium and the substrate a glass plate. To ensure the whole photo-resist surface is exposed the light interference pattern is scanned in orthogonal directions across the surface. This is achieved by two parallel-sided glass plates 35, 36 which are rotated about axes 57, 58 at right angles to each other. The speed of rotation is computed (at 51) to give a uniform time average exposure. The interference light beams 13, 17 are preferably in the blue-violet to Ultraviolet range of wavelengths.
