Title: Supported ziegler catalyst components and their use as polymerisation catalysts
IPC: C08F10/02
Filed: 1975-10-07
Abstract: 1525693 Olefin polymerization catalyst component preparation BP CHEMICALS INTERNATIONAL Ltd 7 Oct 1975 [7 Oct 1974] 43344/74 Heading C3P  An improved particle or slurry form of a supported Ziegler catalyst component is obtained  by (i) mixing the support with a transistion metal compound to cause adsorption thereon, (ii) washing the product to remove excess transition metal compound and (iii) finally adding an inert. organic liquid to the washed product and then evaporating at least 50% thereof. The evaporation may be achieved by passing a stream of gas over the surface of or through the mixture of catalyst and organic liquid or by simply distilling. Examples refer to the treatment of cyclohexane slurries of catalyst components, prepared by treating silica with EtMgBr or MgCl 2  followed by Ti(i-OPr) 4 /TiCl 4  in an i-BuOH or i-PrOH cyclohexane mixture, by passage of nitrogen therethrough until dry powders are obtained, which are used for the homopolymerization of ethylene.

Abstract: 945,788. X - ray diffraction apparatus. RIGAKU DENKI CO. Ltd. Dec. 22, 1959, No. 43595/59. Heading H5R. [Also in Division G1] In a goniometer in which X-rays from a source 3 are reflected by a heated crystal 2 and received by a counter tube 4, the goniometer is rotated so that the counter tube traverses to and fro between fixed stops 5, 6; the output of the counter tube is arranged to operate a recording device such as a moving pen, and as the temperature of the crystal, and hence the lattice spacing, changes, the nature of the recording trace made by the pen indicates such changes. As shown, the output of the counter tube 4 is applied to a relay 11 in an automatic recorder 10. The pen of the recorder is reciprocated in synchronism with the goniometer by a motor 7. The recording paper moves in direction Y, and the pen transversely to this direction. The crystal is heated (or cooled) at a uniform rate. As the radiation received by the moving counter tube passes through a maximum, the recording pen leaves the paper if it has been in contact with it, or makes contact if it has been out of contact. Hence a series of lines as shown in Fig. 2(a) is obtained, the varying pattern indicating the change in lattice spacing of the crystal with change in temperature.

Abstract: 1,005,036. Vacuum forming machines. COMET INDUSTRIES Inc. Dec. 12, 1961, No. 44496/61. Heading B5A. A vacuum forming machine has platens 25, 26 movable vertically by power units comprising electric brake and gear motors 37 mounted on the platens themselves and guided by rack bars 23, a carriage 56 which is slidably mounted on a pair of parallel track rods 50, 51, and a clamping frame 73 for securing a plastic sheet 79 to the carriage. The carriage 56 is moved from a position between the platens to a position between ovens 80, 85 by means of a fluid pressure cylinder 91 acting through pivoted levers 92. An oven door 98 is opened and closed by an air cylinder 100. A plurality of electrical stop switches 108 adjustably mounted on bars 107 limit the extent of movement of the platens. In operation, lower platen 26, with a cavity die connected to an airwithdrawal line 48 is in its lower position and upper platen 25 is in its upper position. The carriage 56 and clamping means are in the forward position between the platens. A plastic sheet 79 is mounted in position and clamped by admitting air into cylinders 65 to operate the clamping frame 73. An electrical impulse introduces air into cylinder 91 causing carriage 56 to move into position between the two ovens 80, 85. Another switch closes the oven door 98 and thermostatically controlled heating elements 82 maintain the desired temperature. The plastic sheet is then moved to a position above the cavity die by reverse operation of the above mechanism. The platens are then caused to move towards each other, and a vacuum pump is operated to withdraw air from the cavity. After an interval sufficient to partially rigidify the plastic in its newly formed shape, the platens are separated and the formed plastic article removed manually or by using compressed air.

A refuse disposal plant comprises consecutive conveyers 5, 6, 7, 8 to take the incoming refuse material for a storage pit 2 to a rotary sieve 11, where the fine material is discharged through the mesh and the larger material is discharged through an outlet 11a on to a conveyer 12 and into a rotary furnace 14. The furnace residue is then picked up by an endless conveyer 15, which discharges it on to a conveyer-elevator 16 from which it falls on to a bump sieve 17. The large material is discharged into an outlet 18, where it is subjected to an electromagnetic unit (18a, Fig. 5) and a mechanical crusher (18b, Fig. 5) to facilitate combustion, if it is to be recycled to the incineration furnace. Fine material for the bump sieve 17 is received by an inclined member 20, while the fine material which passes through the sieve 11 falls directly on to an inclined member 23 and together with the material from the inclined member 20 is collected by a conveyer 24, and conveyed by the latter to an elevator 25, to be loaded into silos 26 and there be transformed into humus and used as a fertilizer. Alternatively the material may be totally incinerated and the ashes removed. In this case fine material from the sieve 11 is intercepted by a movable conveyer 27 and fed to the furnace 14.
