Abstract: 1,224,608. Rolling. UNITED STATES STEEL CORP. 20 March, 1969 [20 March, 1968], No. 14775/69. Heading B3M. An edge-rolling mill stand comprises opposite edge rolls 37 which are moved axially for exchange and each journalled in a chock 34 slidably mounted in housings 22, 22a which are movable relative to the mill centre line and a carrier 74 located between the housings and engagable with the upper ends of the chocks. The stands are used in conjunction with horizontal mills 10, 12, 13 and each mill stand is used with another stand so that four edgerolling rolls are provided between each pair of horizontal mills. The slab S is guided by water cooled guides 18, 19. Hydraulic rams 26 urge the housings together to adjust the pass. Each roll is provided with an hydraulic lifting cylinder 32 whose plunger adjusts the roll axially so that one of the passes 37a, 37b of each roll can be displaced axially when worn. When the rolls are in their upper position a step block 40 is moved under the chock 34 to support it. Lock pins 43 are moved into sockets 42, 42a to lock the chocks in position. The inner wall of each housing has locking plates (50), Fig. 6 (not shown), which are moved by a cylinder (54) into guideways (47), Fig. 5 (not shown), in the chock. The upper end of each roll has a non- circular extension 57 engaged with a vertical movable coupling sleeve 58. The upper end of the sleeve 58 is splined and engages a drive shaft 60 of a drive motor 62. The housings of the adjacent horizontal mills 10, 12, Fig. 7, have cheek plates 72 with tapered sockets 73 to receive lugs 75 of the carrier 74. The lower edge of the carrier is water cooled and acts as an upper guide for the slab S. The carrier 74 can be locked relative to the mills 10, 12 by linkages 77. Each longitudinal side of the carrier has a pair of recesses 85 whose arcs extend through more than 180 degrees. Each recess has a lip 86, Fig. 4, which is engagable with a lip 88 of a ring 87 carried by each of the chocks. The carrier is lifted by a crane 20 with a hook 92 which engages a pin 91 to cause linkage 93, 97 to move locking bars 96 into abutment with the ring 87 when the carrier is lifted. To remove the four rolls of the stands 14, 15 the coupling sleeve 66 is raised, the housings are moved inwards so that the lips overlap and the carrier is lifted to engage the lips and remove the roll assembly from the housing.

Patent GB-616307-A (GB)
Title: Catalytic cracking and catalysts therefor
IPC: B01J35/10
Filed: 1946-05-21
Abstract: A catalyst which may be used in the catalytic cracking of hydrocarbon oils is a synthetic silica-alumina catalyst having between 18 and 38 per cent alumina, an average pore diameter of at least 50 Angstrom units, a surface of at least 400 sq. meters per gm., and a particle density below 0.95.  Such a catalyst may be prepared by treating sodium silicate with sulphuric acid to give a silica sol which eventually settles to a firm hydrogel.  The hydrogel is aged for a time, broken up and leached with acidulated water, and then with aqueous ammonia.  It is then suspended in sufficient aqueous aluminium chloride to yield on precipitation with aqueous ammonia a catalyst containing about 25 per cent alumina, the resulting slurry being filtered and washed free of chloride, dried, and calcined at 565 DEG  C., although calcination before use is not essential. Detailed examples of the preparation of catalysts and of the comparative results of the catalytic cracking of oils using other silica-alumina catalysts and the catalyst described are given.  Among the various factors set out as being concerned in preparing the catalyst, it is stated that it is important to combine the alumina with the silica gel by precipitation in situ and to keep the final pH of precipitation above 6.

Abstract: 1335323 Releasable fastenings STABILUS INDUSTRIE-UND HANDELS GmbH 4 April 1972 [6 April 1971] 15393/72 Heading E2A A lockable lifting device for adjusting the height of chairs and the like comprises a cylindrical container 12 containing a piston rod 1 with a piston 8 and a partition 10 through a passage in which is slidable a push rod 13 displaceable to allow liquid to flow from one side of the partition to the other under the pressure of compressed gas as the position of the rod 1 is adjusted and liquid flows through a bore 15 in the piston 8. The rod 1 has a chamber 6 for compressed gas closed by a floating piston 7. On loading the device, when locked, liquid acting on the piston 7 further compresses the gas and provides a small additional height adjustment and provides a comfortable suspension. Alternatively the rod 1 extends into a container 24 containing compressed gas. The partition may be connected to an end lid 14 by a cylindrical portion through which the rod 13 passes. The rod has a reduced portion 34 to allow liquid flow through a bore 31 and flow is cut off when the reduced portion has passed the bore, thus limiting the movement of the rod.

Cellulose ester and ether solutions, and processes for making filaments therefrom.-Threads of artificial silk are prepared by spinning solutions which contain one or more compounds of cellulose and one or more highly complex compounds obtained by the complete or partial polymerization of unsaturated organic compounds. The complex compounds employed may be derived from acrylic acid esters. The lower polymerization products are preferably employed in the first instance, the polymerization being completed in the threads produced. When a common solvent for the components of the spinning solution is not available, each component may be dissolved in a solvent therefor and the solutions mixed. The example describes a solution or dry spinning containing cellulose acetate, polymerized ethyl acrylate, and methyl acetate, suitable spinning conditions being indicated. Specification 308,284 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the polymerization products may be derived from vinyl esters or ethers, or styrol. It also includes examples in which solutions are described containing (1) cellulose acetate, polymerized vinyl acetate, and acetone; (2) ethyl cellulose, polymerized acrylic acid ester, and acetone; and (3) cellulose acetate dissolved in acetone mixed with metastyrol dissolved in benzene. Each of these solutions is suitable for the manufacture of threads by dry spinning, and suitable spinning conditions are indicated in each case. This subject-matter does not appear in the Specification as accepted.
