Title: Packing cases
IPC: B65D6/00
Filed: 1947-05-08
Abstract: 638,915. Packing cases. PARR, D. E., and SPALDING, T. G. R. May 8, 1947, No. 12531. [Class 18] A packing case has a lid 4 which fits flush between the four side walls 2 and bears on a lining 8, the resilience of the lining permitting the clamping of the contents between the top and bottom of the case. The lid is secured by bands or wires passing round the case and fitting in notches in the upper edges of the walls. The notches render pilfering difficult by preventing the sliding out of the walls. Partitions 10 may be fitted to contain bottles. The case walls and lid are of wood or like rigid material.

Title: Electric terminal block assembly
IPC: H01R9/26
Filed: 1959-04-14
Abstract: 886,855. Terminal boards. BUCHANAN ELECTRICAL PRODUCTS CORPORATION. April 14, 1959 [April 22, 1958], No. 12595/59. Class 38 (1). A single or multiple terminal block is built up of an insulating end section 18 and one or more insulating sections 20 which are identical with each other. Each section 20 comprises a barrier wall 120, Fig. 5, from one side of which projects a platform 56 formed with a recess 60, Fig. 8, and a pair of grooves 58 which are inclined away from one another. The grooves 58 co-operate with a terminal retainer 74, Fig. 11, consisting of an apertured plate 82 with inclined side flanges 84 which engage the grooves so as to retain a terminal 72 in assembled relation with the section 20, the head 80 of the terminal being non-rotatably engaged in the recess 60 and the shank 76 projecting through the aperture in plate 82. The platform 56 is undercut at 34 and recessed at 36, the side walls of the recess being grooved at 46. The end section 18 comprises a barrier wall 118 from one side of which projects a foot portion, slotted at 26 to receive a fixing-screw. A further foot portion 36 projects from the opposite side of wall 118 for engagement, preferably frictionally, in the recess 36 of a section 20, the end of the platform 56 thereof abutting the wall 118 and the end of the retainer 74 being frictionally received in a recess 92 in the wall 118. The side of section 20 opposite that containing the platform 56 is constructed similar to the right-hand side of section 18, as shown in Fig. 5, except that the foot 38 is slotted at 42. Such foot may therefore be used either to receive a fixing screw, or to engage the recess 36 of a further section 20. Specification 792,298 is referred to.

Abstract: 889,410. Contacting a gas or vapour with a liquid. LYDERSON, A. L., and GILDE. R. April 11, 1960 [April 13, 1959], No. 12848/60. Class 55 (2). In a column wherein a gas or vapour is contacted with a liquid there are arranged at space intervals banks of vertical filamentous sheets spaced apart to provide passages for the upward flow of gas or vapour, each sheet being provided over its whole or part of its height with transverse corrugations which catch liquid descending the column and dripping from sheets in the bank above. The sheets are supported from beams d and by rods c and some of the transverse filaments of the sheets may be removed as shown at a to improve distribution of liquid over the sheets. Vertical filaments of the sheets may project at the lower edges of the sheets as shown and the corners may be cut off to prevent liquid flowing to the walls of the column. Plates f may be provided on the walls of the column to direct liquid flowing down the walls of the column on to the filamentous sheets.

Title: Mixed organo-metal catalysts and their use in polymerisation processes
IPC: B01J27/06
Filed: 1960-04-11
Abstract: The invention comprises a polymerization catalyst obtainable by reacting a titarium halide with an alkylaluminium halide, and having a debyeogram which shows new lines in addition to some of the lines characteristic of pure crystalline titanium and aluminium trihalides, the catalyst having the composition AlTiIII1-2.5 X5.5-8R0.1-2 (X=halogen, preferably Cl:R= C2-8alkyl).  Such catalyst is prepared as a dispersion in an inert solvent by reacting the titanium and alkylaluminium halides at -20 to +40 DEG C. in an inert solvent and heating the dispersion so obtained for 0.2 to 8 hours at 60-120 DEG C. and optionally washing with inert hydrocarbon followed by heating with an alkylating compound, e.g. Et2AlCl and repeating the washing step.  The catalyst is used to produce isotactic polyolefins from R1CH=CH2, R1 being an aliphatic aromatic cycloaliphatic or mixed radical containing up to 12 carbon atoms, e.g. from propylene, butadiene, pentadiene or isoprene.  Specifications 799,392, 810,023, 810,024, 828,201, 828,791 and 863,416 are referred to.

Title: Improvements relating to the cracking of hydrocarbon oils
Filed: 1934-04-30
Abstract: <PICT:0425726/III/1> In a process for cracking oils in which intermediate and heavy fractions are separated from the crude oil and cracked separately.  Crude oil supplied through a pipe 8 and separated if required from light fractions by preheating in coils 9, 10 and flashing in the upper portion 11 of a tower 1 is fed through a pipe 19 into the intermediary part of the lower portion 18 of the tower, where it is fractionated in counter current with hot vapours from a cracking furnace 5.  A condensate is collected on a pan 28 and led through a pipe 32 into the middle of an evaporating tower 2 where it is further distilled in counter current by hot vapours led through a pipe 7<a> from a vapour phase cracking furnace 6 and soaking drum 7.  A condensate is collected in a pan 36 and constitutes the stock collected in a drum 41 for the cracking furnace 5 the vapours from which are led through a pipe 21 into the bottom of the tower 1.  Tar is withdrawn from the bottom of the evaporator 2 and flashed in a tower 56 and the vapours evolved are led through a pipe 57 into the tower 18, while the vapours evolved in the evaporator 2 are led through a line 44 into a fractionating tower 3, the reflux collecting in the bottom of this tower constituting the stock for the vapour phase cracking zone 6.  Residual oil collecting in the bottom of the tower 18 may be flashed with steam and then withdrawn to storage or directed through lines 70, 72 to mix with residues from the tower 3 or to a tank 73 to serve as a flushing medium to flush out carbon accumulating in the line 7<a>. Final light distillates are recovered through pipes 12, 24, 48 and led through condensers 13, 25, 49 to receivers 14, 26, 50 while a gas oil fraction may be withdrawn from a plate 27 to a receiver 31.  The low temperature cracking zone 5 is operated at about 860 DEG  F. and 200 lbs. per sq. inch while temperature of about 960 DEG  F., is maintained in the zone 6, the cracking per pass in the zones 5, 6, being 8--10 per cent and 13--15 per cent respectively.
